Algae Offer Great Potential for Energy Production

The idea that algae can be used for the production of green energy is not new, and numerous universities have presented their concepts of facilities that generate electricity using these organisms.

Among them are researchers from Concordia University in Canada, who recently published their work in the scientific journal Energies. In this study, scientists describe how they managed to produce electricity from the photosynthesis process of algae, since photosynthesis produces oxygen and electrons.

The scientists’ idea is to “capture” electrons and thereby generate electrical energy. For this purpose, they created small energy cells in which they placed algae dissolved in a specialized suspension.

Properly configured, these cells can generate enough energy to power low and ultra-low-power devices such as IoT sensors.

However, although the amount of electricity obtained from algae is currently small, this method gives hope that soon we could have large-scale generators producing significant amounts of electrical energy from algae.

In addition to being widely available and practically free, this method of obtaining electricity offers another advantage over other renewable energy sources because it absorbs carbon dioxide.

“This technology is more than zero-carbon technology – it is a negative-emission technology because it absorbs carbon dioxide from the atmosphere and produces electricity. Its only by-product is water,” says one of the study’s authors, Dr. Kirankumar Kuruvinashetti.

They Produce Electricity Even at Night

Despite their lower intensity, algae can generate electricity even without direct sunlight, explains co-author Dilipan Panersalvem.

“Just like humans, algae breathe continuously – they take in carbon dioxide and release oxygen. Because of their ability to photosynthesize, they also release electrons during respiration. The production of electrical energy does not stop; electrons are continuously collected,” says Panersalvem.

He believes that with enough research and development, including AI-assisted integration technologies, this technology has the potential to be a sustainable, affordable, and clean energy source in the future.

What Happens When the Lifespan of Solar Panels Ends? Is There a Reason for Concern?

New technologies bring hope for a better and safer future, but at the same time, they also bring anxiety – what negative consequences might they leave behind? Electric vehicles, for example, are criticized because of the energy storage batteries and the lithium required for their production. When it comes to solar panels, which offer us a clean energy source, there is debate about what happens when they become waste. How much will they pollute the environment? Can they be recycled?

Reflecting on this topic, I found an article with conclusions I would like to share.

Numerous and powerful industries are involved in the energy transition. Humanity is filled with both good and evil. Evil includes the desire for power, greed, and recklessness. Although we should be more united than ever in transitioning to a green and sustainable way of life, it cannot be overlooked that some don’t find this to be in their interest. In terms of energy transition and ecology in general, it is essential to highlight the concept of greenwashing, which powerful industries use daily. Therefore, those who harbor distrust towards green technologies cannot be blamed.

Greenwashing is a broad term. In the context of green technologies, this could be explained by companies presenting their products as environmentally sustainable, which they indeed are to some extent. However, they hide that these technologies are not 100 per cent ecological. This is precisely the example I mentioned at the beginning. While electric vehicles are presented as non-polluting because they do not use fossil fuels, producing their batteries requires lithium mining, which is not widely discussed.

Returning to the initial topic, solar panels could similarly be questioned. Although they help reduce carbon dioxide emissions and other pollutants, how much do we know about their different characteristics? What is required for their production, how much emission is released during the process, and what happens when their lifespan ends? Can they be recycled, or do they cause more environmental pollution after their lifespan than the benefits they provided during their operation?

The article I mentioned points out several arguments in favor of solar panels. Firstly, this industry is still relatively young and has room to develop to become more sustainable, and the recycling sector is improving on a daily basis. Besides room for improvement, there is also time for improvement because the lifespan of this technology is up to 30 years. Considering this, solar panels are long-lasting. They are not like phones, which are sold in large quantities and are often replaced every two years.

The second point discussed in the article is the material from which solar panels are made. It is stated that over 70 per cent of the material is glass, which has a well-developed recycling capability – in other words, it is recyclable. Although it has its specificities, like any object and technology where certain materials are adapted and improved, the current development of glass recycling infrastructure optimistically suggests that the process for recycling this glass will also develop. The other materials are metals, such as aluminum and copper wires, which also have good recycling potential and can be reused in this industry. Even if some older models of solar panels contain hazardous materials, such as lead, they appear in small quantities. Additionally, these hazardous materials are not released during the operation of the panels. If solar panels are correctly managed after their lifespan, they will not end up in the environment.

There are also companies dedicated explicitly to recycling solar panels, which means that work on this matter is already well underway.

The final argument presented compares fossil fuels and solar energy in the context of which option has a greater negative impact. Even if solar panels as waste create some negative environmental impact, they are still a cleaner solution than fossil fuels. From coal, oil, and natural gas mining to pipeline and tanker transport, spills can occur due to the pollution generated during use. There is also coal ash, which could be considered waste after the coal’s life cycle and is very harmful.

Ultimately, fossil fuels are a limited resource. Therefore, finding alternative solutions and giving them a chance to develop as effectively as possible is necessary.

If we go back to the initial issue of lithium mining to produce batteries for renewable energy storage, it should be noted that this matter is already being addressed. We are finding new materials that could replace the use of lithium and be more sustainable.

Eurostat released the publication ‘Sustainable development in the European Union – monitoring report on progress towards the SDGs in an EU context – 2024 edition’. This publication provides readers with a statistical overview of the EU’s progress towards its Sustainable Development Goals (SDGs).

The Eurostat monitoring report shows that, based on the assessment of the past five years of available data, the EU made progress towards most of the SDGs, while it fell slightly behind in a few goals.

The EU has made very significant progress in terms of reduced inequalities (SDG 10) and decent work and economic growth (SDG 8) with several indicators reaching record values. Significant progress has also been made in terms of no poverty (SDG 1).

There were good achievements concerning the goals on sustainable agriculture (SDG 2), innovation and infrastructure (SDG 9), sustainable consumption and production (SDG 12), life below water (SDG 14), quality education (SDG 4) and gender equality (SDG 5).

Meanwhile, the goals on peace, justice and strong institutions (SDG 16), sustainable cities and communities (SDG 11), global partnerships (SDG 17) made moderate progress in the EU. This was also the case for SDG 13, climate action.

More:

Regarding the goal on clean water and sanitation (SDG 6), several indicators show positive developments, but others show no progress or even movement away.

For affordable and clean energy (SDG 7), a slight movement away was observed in terms of energy affordability and the EU’s energy import dependency due to the negative impact of Russia’s war of aggression against Ukraine and the consequent energy crisis in the EU.

The goal on health and well-being (SDG 3) was affected by the setbacks of the COVID-19 pandemic that are now fully visible in the available data.

The goal on life on land (SDG 15) is characterised by several unsustainable trends in the areas of biodiversity and land degradation, leading to a moderately unfavourable assessment of the EU’s progress in this area over the short-term period assessed.

The EU SDGs indicators set is structured along 17 goals, with 102 indicators, reviewed every year, aligned but not identical to the UN SDG indicators used as the basis for monitoring progress towards the SDGs in an EU context. Many of the indicators are also used to monitor existing policies as the 8th Environment Action Programme and the European Pillar of Social Rights Action Plan.

The European Union launched the European Green Deal, paving the way for a comprehensive approach to green in all sectoral policies. The Green Deal was extended to the Western Balkans in the form of the Green Agenda, which was adopted by all the countries of the region. The Deal’s priorities are decarbonization, the  fight against pollution, biodiversity, circular economy, and food systems.

The EU provides support in various forms – technical assistance to ministries when drafting laws and policies, investments, especially in wastewater treatment plants and waste centers and assistance with policy dialogues, including attracting public attention through various public events and the media. The Green Agenda for Serbia project successfully supports green innovations pilot projects.

We spoke with Antoine Avignon, Programme Manager for Environment and Climate Changes at the EU Delegation to the Republic of Serbia, about how they support the processes of green transition, whether we are doing enough on implementing mechanisms to reduce harmful gas emissions, the legal framework for the adoption of the National Energy Climate Plan in Serbia (NECP) and facilitating education and the development of awareness about environmental protection.

IN FOCUS:

Q: In what other ways does the EU Delegation support implementing the green transition in Serbia?

A: The very process of European integration is a process through which Serbia becomes green. To help Serbia become green, the European Union has invested 582 million euros in environmental protection. Thanks to our projects related to gas pipelines, there will be less harmful emissions and less polluted air. The EU supports Serbia in achieving its own environmental protection and climate action goals to gradually raise them to the EU level while boosting the awareness of individuals, the private sector, and the media. The most important results of this support to Serbia are constructing wastewater treatment plants in Subotica, Šabac, Leskovac, Kula, Vrbas, Raška, Niš, Kraljevo, Brusand Blac. The support also includes renovating the water supply system in Požarevac, Inđija, and Petrovac na Mlavi. Also, a water supply system was built from the ground up in Veliko Gradište. The EU financed the ash disposal system and the installation of the filtration system at the Nikola Tesla TPP. Equipment for monitoring the emission of harmful substances has also been installed in TENT A and B and Kolubara TPP. Regional landfills were built in Pirot, Užice, Sremska Mitrovica, Šabac and Subotica. A medical waste management system has also been developed. The first regional sanitary landfill in Duboko was opened thanks to EU assistance. It now serves nine municipalities in western Serbia and stores 80,000 tons of waste annually. The EU financed the flood defense system in Šabac with 10 million euros. In Subotica, the Delegation funded the construction of a modern Regional Waste Management Centre with 20.3 million euros.

Q: Is enough being done to implement mechanisms to reduce harmful gases in Serbia? How are we progressing towards reducing greenhouse gas emissions by 50 per cent by 2030?

A: The data on the emission of harmful gases show that the biggest source of sulfur and nitrogen oxides and suspended particles is fuel combustion, which happens during electricity and heat production. At the same time, road traffic contributes to emissions to a lesser extent. The EU also financed the installation of 28 measuring stations and instruments for automatic monitoring of air quality. In February 2020, when air pollution in Serbia was above permissible limits for days, the EU supported Serbia in taking action and addressing this issue to prove how the European integration process can be helpful by offering expertise, examples of good practices, and investments. The emission of particles into the air above Obrenovac and its surroundings has been reduced by as much as six times.

Q: The Rulebook on the Detailed Content and guidelines for Determining the National Goals of the Integrated National Energy and Climate Plan (NECP) was approved. Is there a sound legal framework and legislative system for adopting the NECP?

Photo-illustration: Unsplash (Thomas Reaubourg)

A: The Law on Energy lays a good foundation for the drafting and adopting the NECP. We provided technical assistance over four years to prepare and develop the first NECP that covers the period until 2030. This is a highly demanding and challenging process for countries that rely on fossil fuels and traditional inefficient energy use. Serbia has numerous other opportunities, technologies, and policies at its disposal that could diversify energy sources, bring additional renewable energy, and reduce consumption. It is essential to point out that the lower ambitions of the Serbian NECP are to achieve climate neutrality by 2050 and even by 2030 in terms of renewable energy sources and energy efficiency. We are following this process. We will help Serbia increase its targets during the implementation and reporting of the NECP in the coming years. Next year, Serbia should finalize and adopt the NECP, following the energy and climate goals of the Energy Community covering the period until 2030, considering the recommendations of the Energy Community Secretariat and the energy sector.

Photo-illustration: Pixabay

The Council formally adopted the – first of its kind – regulation on nature restoration. This law aims to put measures in place to restore at least 20 per cent of the EU’s land and sea areas by 2030, and all ecosystems in need of restoration by 2050.

It sets specific, legally binding targets and obligations for nature restoration in each of the listed ecosystems – from terrestrial to marine, freshwater and urban ecosystems.

The regulation aims to mitigate climate change and the effects of natural disasters. It will help the EU to fulfil its international environmental commitments, and to restore European nature.

The new rules will help to restore degraded ecosystems across member states’ land and sea habitats, achieve the EU’s overarching objectives on climate mitigation and adaptation, and enhance food security.

The regulation requires member states to establish and implement measures to jointly restore, as an EU target, at least 20 per cent of the EU’s land and sea areas by 2030.

The regulation covers a range of terrestrial, coastal and freshwater, forest, agricultural and urban ecosystems, including wetlands, grasslands, forests, rivers and lakes, as well as marine ecosystems, including seagrass and sponge and coral beds.

More:

Until 2030, member states will prioritize Natura 2000 sites when implementing the restoration measures.

In recent decades, the abundance and diversity of wild insect pollinators in Europe have declined dramatically. To address this, the regulation introduces specific requirements for measures to reverse the decline of pollinator populations by 2030 at the latest.

The regulation sets out specific requirements for different types of ecosystems, including agricultural land, forests and urban ecosystems.

Member states will put in place measures aiming to restore drained peatlands and help plant at least three billion additional trees by 2030 at the EU level. In order to turn at least 25 000 km of rivers into free-flowing rivers by 2030, member states will take measures to remove man-made barriers to the connectivity of surface waters.

Under the new rules, member states must plan ahead and submit national restoration plans to the Commission, showing how they will deliver on the targets. They must also monitor and report on their progress, based on EU-wide biodiversity indicators.

The regulation will now be published in the EU’s Official Journal and enter into force. It will become directly applicable in all member states.

By 2033, the Commission will review the application of the regulation and its impacts on the agricultural, fisheries and forestry sectors, as well as its wider socio-economic effects.

ACEA takes note that the European Commission has decided to impose provisional countervailing duties on imports of electric cars manufactured in China, based on initial findings of an anti-subsidy investigation initiated last year.

ACEA has consistently affirmed that free and fair trade is essential in creating a globally competitive European automotive industry, while healthy competition drives innovation and choice for consumers.

Free and fair trade means guaranteeing a level playing field for all competitors, but it is just one important part of the global competitiveness puzzle.

More:

“What the European automotive sector needs above all else to be globally competitive is a robust industrial strategy for electromobility,” stated ACEA Director General, Sigrid de Vries. “This means ensuring access to critical materials and affordable energy, a coherent regulatory framework, sufficient charging and hydrogen refilling infrastructure, market incentives, and so much more.”

The investigation will continue for several months until the Commission decides whether to propose definitive anti-subsidy measures. Member states will then vote on such a proposal.

Soil Monitoring Law: EU on the Pathway to Gealthy Soils by 2050

The general approach reached by the Council today aims to make soil health monitoring obligatory, provides guiding principles for sustainable soil management and addresses situations where soil contamination poses unacceptable health and environment risks.

Healthy soils are the foundation for 95 per cent of the food we eat, host more than 25 per cent of the biodiversity in the world and are the largest terrestrial carbon pool on the planet. Yet, soil is a limited resource and over 60 per cent of soils in the EU are not in a good condition.

‘’Humans and our ecosystems depend on soil as a source of food, clean water, and habitat. But it is a non-renewable resource which needs to be protected and restored. Today, we are taking an important step towards healthy soils in the EU by 2050’’, Alain Maron, minister of the Government of the Brussels-Capital Region, responsible for climate change, environment, energy and participatory democracy.

Comprehensive monitoring framework

Member states, supported by the Commission, will first monitor and then assess the health of all soils in their territory, so that sustainable soil management practices and other appropriate measures can be taken by authorities and landowners across the EU. Member states will determine sampling points for monitoring, on the basis of an EU common methodology.

The general approach includes additional flexibilities to member states regarding soil measurements, including the possibility to use existing data and monitoring systems. It also sets out the minimum quality requirements for laboratories analysing soil samples to ensure the comparability of soil measurements.

More:

Assessment of soil health

The general approach shares the Commission proposal’s ambition on assessment of soil health, maintaining the concept of soil descriptors (physical, chemical and biological parameters). In order to adapt to local circumstances, a more flexible double-value system was agreed in the Council to assess soil health:

  • non-binding sustainable target values at EU level to reflect the long-term objectives
  • operational trigger values, set at member states level for each soil descriptor, in order to prioritise and gradually implement measures leading to a healthy soil status

Sustainable soil management

According to the general approach, member states will define practices on sustainable soil management within five years of the directive entering into force, taking into account the guiding sustainable soil management principles set out in the directive.

Land take mitigation

While maintaining the aspirational long-term objective to have no net land take by 2050, the general approach is centred on tackling soil sealing and soil destruction, as the most visible, the most impactful and the easiest to monitor aspects of land take.

It sets out mitigation principles to be taken into account in member states’ land use planning, which are sufficiently flexible to respect member states’ spatial planning decisions, including on housing and energy transition measures.

Contaminated sites

According to the proposed directive, member states will identify all potentially contaminated sites, then map them in a public register.

The general approach introduces a risk-based and stepwise approach. This will allow member states to prioritise measures, taking into account the potential risks, socio-economic context and the current and planned land use. To help identify potentially contaminated sites, ministers agreed on establishing national lists of potentially contaminating activities.

Once a contaminated site has been identified, it will be investigated, and any unacceptable risks for human health and the environment will be addressed.

Next steps

The general approach reached by the Council will allow its rotating presidency to start talks with the European Parliament on the final shape of the text. Negotiations are expected to start under the new legislative cycle.

Increasing Energy Investment in Africa is Vital for the Continent’s Sustainable Economic Growth

Photo-illustration: Pixabay

Meeting growing energy demand in Africa requires a surge of spending on clean energy projects, with swift action to tackle financial barriers so investment can reach the levels that are needed, according to a new report from the International Energy Agency (IEA).

The report, Clean Energy Investment for Development in Africa, supports a flagship initiative launched today by Italy’s G7 Presidency at the Leaders’ Summit in Apulia. Called Energy for Growth in Africa, it aims to help foster a strong pipeline of bankable clean energy projects in Africa and to improve access to financing so the projects can come to fruition, with an emphasis on technical assistance and capacity building.

The IEA will be the initiative’s key knowledge partner, working alongside the United Nations Development Programme, which will focus on implementation. Energy for Growth in Africa – which will complement existing initiatives among G7 members, including the Partnership for Global Infrastructure and Investment (PGII), Global Gateway, and Just Energy Transition Partnerships – will initially collaborate with the Republic of Congo, Côte d’Ivoire, Ethiopia, Kenya, Mozambique, Nigeria and South Africa.

Clean Energy Investment for Development in Africa lays out the opportunities and challenges of accelerating the sustainable development of Africa’s energy infrastructure. Despite the continent’s immense energy resources, it currently attracts only around 3 per cent of global spending on energy. About 600 million Africans still lack access to electricity, and more than 1 billion cook their meals over open fires and traditional stoves using wood, charcoal, kerosene, coal or animal waste.

More:

According to the report, meeting Africa’s rising energy needs, as well as the energy access, climate and development goals set by governments in the region, requires annual energy investment to more than double to over 240 billion dollars by 2030, with around three-quarters going to clean energy. The report outlines key target areas for investment, including energy access, the power sector and emerging industries, such as critical minerals and the manufacturing of clean energy technologies.

It also highlights strategies to boost financing for energy investments in Africa, which remains difficult due to higher perceived risks and elevated borrowing costs compared with other parts of the world. In emerging and developing economies, the cost of capital can be two to three times higher than in advanced economies. The report emphasises that concessional finance is therefore key, especially to unleash more funding from the private sector. Africa’s energy systems require, on average, 30 billion dollars in concessional finance annually to 2030 to help realise the three-fold increase in private sector investment needed over the same period, according to the IEA analysis.

“The lack of energy access in Africa is a great injustice, but increased spending on impactful projects could quickly turn the tide,” IEA Executive Director Fatih Birol said. “Our new report outlines the immediate investment priorities and the financing mechanisms needed to rapidly make these projects a reality. We are pleased this issue is high on the G7 agenda and stand ready to work closely with our partners in Africa and beyond to turn promises into action, including through the G7’s Energy for Growth in Africa initiative.”

The IEA has been working on energy and climate issues in Africa for decades. It now has five Association countries in Africa – Egypt, Kenya, Morocco, Senegal and South Africa – and collaborates with many more on a wide range of energy issues. In May, the IEA and its partners hosted the first ever high-level Summit on Clean Cooking in Africa, mobilising 2.2 billion dollars in financial pledges from governments and the private sector in an effort to make 2024 a turning point on clean cooking access.

The companies B2 Nova Sun, B2 Sunspot, and Elektroprivreda Srbije, a joint stock company, signed electricity purchase and balance responsibility contracts for two solar power plants. B2 Nova Sun – Nova Crnja in Banat and B2 Sunspot – Kikinda are the first solar power plants with whom EPS signed these contracts based on auctions conducted by the Ministry of Mining and Energy. Both solar power plants signed 15-year agreements on the purchase of electricity and the assumption of balance responsibility in trial and permanent operation.

“The purchase and balancing price is determined by market principles. This energy will provide additional security for the operation of our power system and supply for citizens and businesses. It will be sufficient to supply about 10,000 households”, said David Žarković, Executive Director for Energy Portfolio Management at EPS JSC.

Elektroprivreda Srbije is a reliable partner for all companies that have decided to increase the share of energy from renewable sources in Serbia’s energy mix through market premiums auctions. With the investors who participated in the auctions and other independent producers in Serbia, we already have more than one GW of installed capacity from renewable sources, more than 10 per cent of Serbia’s production capacity. With slightly more than 30 per cent of EPS production from the hydro sector, we are already rapidly approaching 50 per cent production from renewable energy sources.

IN FOCUS:

The solar power plant B2 Sunspot is located in the non-building area of the city of Kikinda, at the location of the former landfill. This makes this project exceptional because it is the first power plant in the region to be built on a reclaimed old landfill, which is given a new use with this investment. The planned connection power of this power plant is 7 MW. The solar power plant B2 Nova Sun, with a connection power of 9.9 MW, is being built on a plot in the industrial part of Nova Crnja, right next to the former Sugar Factory. This investment completes the Municipal Plan on the Promotion of Renewable Energy Sources.

Miloš Kostić, director of the companies B2 Nova Sun and B2 Sunspot, says that the electricity purchase contracts with Elektroprivreda Srbije are a continuation of the previously signed market premium contracts also concluded with this joint-stock company. A price of 89.7 euros per MWh was accepted for both solar power plants. Both power plants have obtained building permits and signed turnkey construction contracts with the company MT-KOMEX. All the necessary equipment has been purchased for both power plants, and construction is underway.

“In Nova Crnja, the works are slowly coming to an end, and when it comes to the power plant in Kikinda, it is estimated that 40 per cent of the works have been completed”,  Kostić said, adding that the solar power plant in Kikinda is expected to be connected to the grid at the beginning of May.

The total annual production of these two solar power plants will be 25,000 MWh. The power plants were financed partly from investors’ funds, while the other part was financed from loans from two banks. Kostić pointed out that despite the large number of requests and interests of other investors, obtaining all necessary permits went as expected, stressing that all procedures were started on time. He adds that they are continuing their investments in this way; last year, they put into operation the Delasol power plant in Lapovo, with a capacity of 9.9 MW. This is the natural follow-up of the company – as a domestic investor, to increase the share of renewable sources in the energy sector of the Republic of Serbia.

Development of Environmental Protection

Humanity’s contemplation about its negative impact on nature has left a written trace dating back several centuries. Yet, at that time, there was not enough knowledge about the extent to which such an attitude towards the environment could lead. More serious environmental awareness and protection development required humanity to realize another important moment – humans are not alone on this planet. This was the moment when man’s consciousness became imbued with concern for other beings, thus abandoning the exclusive concern for the survival of the human species. Even today, we can’t say with certainty that that moment has been fully experienced, but we can confirm that the 1960s marked the beginning of humanity’s progress from anthropocentrism to ecocentrism. There are countless ups and downs in the human relationship with nature that have been recorded from that time to date. Below, we present some of the moments that were significant for the development of environmental protection for all living beings.

The founding of the WWF and the revolutionary Silent Spring

The early 1960s saw the formation of the World Fund for Nature (WWF) as an international non-governmental organization that aimed to provide financial resources to help protect the natural environment and biodiversity threatened by human development and activities. According to many, an American zoologist and biologist, Rachel Carson, occupied a special place in the silent birth of the environmental revolution, who expressed her love for nature through writing. Although books from the earlier decades were also notable, the one that made the strongest impact was 1962’s Silent Spring. The author showed courage to write about a topic beyond her time, thus pointing out the dangers of DDT (a type of insecticide) in the living world.

Her work later led to a ban on using this insecticide in the United States for agricultural purposes. Still, more importantly, it raised awareness and instilled courage to protect nature from pollutants. Another important moment in this decade, in terms of the conservation of the living world, happened in 1964 when the International Union for Conservation of Nature (IUCN) was founded, known for the Red List of Endangered Species it publishes, which contains the most comprehensive information on status and risk from the extinction of species.

Stockholm Declaration and Earth Day

The first observance of Earth Day on April 22, 1970, opened the door for important events in the next decade. On that day, approximately 20 million people in the United States participated in events that took place in tens of thousands of locations across the country. Twenty years later, Earth Day officially became a global day, when on April 22, 1990, about 200 million participants in more than 140 countries worldwide took part in marking this day. Two years later, the first global conference was held in Stockholm with the issue of the environment as the main topic – the United Nations Conference on the Human Environment. Several important decisions were made at this event – the famous Stockholm Declaration and the Environmental Action Plan were adopted. The declaration laid down 26 principles for preserving and improving the environment, focusing on the need for international cooperation in this matter. As a result of the Stockholm Conference, the United Nations Environment Program (UNEP) was established, which, thanks to its long-standing work with governments, civil society, the private sector, and other UN bodies, is dedicated to resolving the most urgent environmental problems.

Although the Club of Rome, an international organization made up of experts from various fields, was formed in 1968 to study and promote sustainable development policy, it is listed chronologically in this part of the article. Namely, in 1972, the Club of Rome published its famous report called The Limits to Growth, which analyzed current trends and gave projections related to population growth while also presenting worrying information that indicated that the planet Earth, with its organized resource capacity, would not be able to keep up with such human population growth and needs for using resources. The report could be described as a catalyst for developing awareness about the need to apply sustainable development principles.

Two more important events that marked the 1970s are the Convention on International Trade in Endangered Species of Wild Flora and Fauna (CITES) from 1973 and the Convention on Transboundary Air Pollution (CLRTAP) from 1979. The CITES convention was signed by 184 countries and was adopted to ensure that international trade in plants and animals did not threaten their survival in the wild. The main reason for the CLRTAP Convention was people’s growing dissatisfaction due to the harmful effects of acid rain in Europe. As the first regional convention related to environmental protection, it entered into force in 1983 to reduce pollution from the biggest polluters in Europe and North America. Since its adoption, it has been expanded with several Protocols specifically targeting pollutants such as nitrogen oxide, ammonia, toxic heavy metals, sulfur, and others. Over the years, the Convention has seen significant success in reducing pollutant levels. Official data collated by the United Nations Economic Commission for Europe (UNECE) show that between 1990 and 2006, carbon dioxide levels fell by 70 per cent in the European Union and by 36 per cent in the United States, while in the same period, the PM 10 particle levels were reduced by 28 per cent in the European Union.

Can Floating Solar Power Plants Cover the Entire Energy Consumption of a Country?

Certain countries have huge potential when it comes to floating solar power plants, and new research shows that some of them could be entirely dependent on this energy source.

Researchers from Bangor and Lancaster Universities and the UK’s Centre for Ecology and Hydrology wanted to calculate the global potential for building floating solar power plants with a low carbon footprint.

Their study, published in Nature Water, included nearly 68,000 lakes and reservoirs worldwide suitable for installing floating solar panels because they are located near populated areas, are not in protected areas and meet other sustainability criteria.

Taking into account all factors such as altitude, latitude and season, the scientists calculated that the potential for annual electricity production from floating solar farms is 1,302 terawatt-hours per year, which is around four times the UK’s total annual electricity demand.

More:

The research also found that Papua New Guinea, Ethiopia and Rwanda could cover their electricity needs from floating solar power plants. At the same time, Bolivia and Tonga would come very close, with an estimated 87 and 92 per cent, respectively.

In Europe, Finland could cover 17 per cent of its electricity demand this way, Denmark 7 per cent, and Great Britain only 1 per cent.

Experts estimate that floating solar power plants have several advantages compared to ground and roof ones.

In addition to preventing excessive water evaporation on hot days, floating solar panels limit light flow and thus reduce algae blooms. Another benefit of floating solar plants is the fact that they free up land for other purposes. On the other hand, water cools the solar panels, allowing them to function more efficiently.

However, many scientists agree that more research is needed on the environmental impacts of floating solar power plants.

Progress on Basic Energy Access Reverses for First Time in a Decade

A new report by the International Energy Agency (IEA), the International Renewable Energy Agency (IRENA), the United Nations Statistics Division (UNSD), the World Bank, and the World Health Organization (WHO), released today, finds that the world remains off course to achieve the Sustainable Development Goal (SDG) 7 for energy by 2030.

SDG 7 is to ensure access to affordable, reliable, sustainable and modern energy. The goal includes reaching universal access to electricity and clean cooking, doubling historic levels of efficiency improvements, and substantially increasing the share of renewables in the global energy mix. Attaining this goal will have a deep impact on people’s health and well-being, helping to protect them from environmental and social risks such as air pollution, and expanding access to primary health care and services.

The 2024 edition of Tracking SDG 7: The Energy Progress Report warns that current efforts are not enough to achieve the SDG 7 on time. There has been some progress on specific elements of the SDG 7 agenda – for example, the increased rate of renewables deployment in the power sector – but progress is insufficient to reach the targets set forth in the SDGs.

The latest report confirms that the number of people without access to electricity increased for the first time in over a decade, as population grew – mostly in Sub-Saharan Africa – at a higher rate than that of new electricity connections, leaving 685 million people without electricity in 2022, 10 million more than in 2021. A combination of factors contributed to this including the global energy crisis, inflation, growing debt distress in many low-income countries, and increased geopolitical tensions. However, promising trends in the rollout of decentralised energy solutions, largely based on renewable energy, are helping accelerate progress, particularly in rural areas where eight in ten people without access live today.

Meanwhile, 2.1 billion people still live without access to clean cooking fuels and technologies, with the number remaining largely flat last year. This carries with it huge implications for health, gender equality, and the environment, contributing to 3.2 million premature deaths each year. Renewed political momentum within the context of G7, G20, and new financial commitments made at the Summit on Clean Cooking in Africa are buoying prospects for stronger progress later this decade. Still, efforts remain insufficient to reach universal access to electricity or clean cooking by 2030.

Other parts of the SDG 7 agenda have fared better recently. Renewable energy has seen robust growth over the past two years, and energy efficiency improvements is gradually improving after a drop-off during the pandemic, albeit still not enough to meet the SDG 7 target. New global targets pledged by over 130 countries in the UAE Consensus reinforce the objectives of SDG 7 by aiming to triple renewable generating capacity and double the rate of energy efficiency. Immediate concrete actions are required to fulfil these targets, especially in addressing the large disparity in clean energy investment, of which 80 percent remains concentrated in just 25 countries in 2022.

Key findings of the report:

  • 2022 saw a reversal in progress, with the number of people living without electricity growing for the first time in over a decade. Today, 685 million people live without access – 10 million more than in 2021. In 2022, 570 million people in sub-Saharan Africa are living without electricity, accounting for more than 80 percent of the global population without access. The access deficit in the region has seen an uptick relative to 2010 levels.
  • The world remains off track to achieve universal access to clean cooking by 2030. Up to 2.1 billion people still use polluting fuels and technologies for cooking, largely in Sub-Saharan Africa and Asia. The traditional use of biomass also means households spend up to 40 hours a week gathering firewood and cooking, which makes it difficult for women to pursue employment or participate in local decision-making bodies and for children to go to school.
  • Household air pollution created by using polluting fuels and technologies for cooking results in 3.2 million premature deaths each year.
  • Renewable electricity consumption grew more than 6 percent year-on-year in 2021, bringing the share of renewables in global electricity consumption to 28.2 percent.
  • Installed renewable energy-generating capacity per capita reached a new record in 2022 at 424 watts per capita globally. However considerable disparities exist. Developed countries (at 1,073 watts per capita) have 3.7 times more capacity installed than developing countries (at 293 watts per capita).
  • The rate of energy intensity improvement saw a slight advance of 0.8 percent in 2021 compared with 0.6 percent a year earlier. However, this remains well below the long-term average. The slow progress in 2021 occurred amidst the robust economic recovery after the COVID-19 pandemic, which saw the largest annual rise in energy consumption in 50 years. Average annual improvements through 2030 must now accelerate to over 3.8 percent to meet the SDG 7.3 target.
  • International public financial flows in support of clean energy in developing countries rebounded in 2022, to USD 15.4 billion, a 25 per cent increase over 2021. However, it is still around half of the 2016 peak of USD 28.5 billion.
  • By 2030, under current policies there are still 660 million people lacking electricity access and around 1.8 billion without access to clean cooking technologies and fuels. Progress in energy efficiency rates also lags, reaching just 2.3 percent, well below the level needed to reach the SDG 7 target.

Do You Know What a Digital Carbon Footprint is and How to Reduce It?

Clicking, liking, sharing, scrolling – the Internet has given us the world in the palm of our hands and practically “infected” us with these online activities that most of us cannot imagine a day without.

However, no matter how benign our online time seems, its background hides a real ecological threat exacerbating the climate crisis by the minute.

Each of our clicks travels through a complex Internet infrastructure that consumes a staggering amount of electricity, and since electricity is primarily derived from fossil fuels, the longer we surf the Internet, the larger our digital carbon footprint.

Data centers are the biggest electricity consumers, as they store and process a vast amount of data. These centers have numerous servers and supporting equipment that consumes electricity at the speed of light, and their carbon footprint has never been higher.

In addition to requiring a continuous supply of electricity derived from fossil fuels, data centers heat up quickly, so they also need constant cooling.

This means that additional energy is used to power cooling devices, while some data centers use water for cooling. One study found that many data centers in the US are located in drought-prone areas, but that doesn’t stop them from drawing huge amounts of precious water.

Although the story of the unsustainability of data centers continues, we have to ask ourselves what we can do to reduce our digital carbon footprint.

Some data centers have turned to green technologies and circular economy, so they use energy from renewable sources, hand over waste heat to heating plants for heating local communities and implement a number of other innovative solutions that improve their sustainability.

While these are great examples of how data centers can become greener while maintaining maximum operational efficiency, they are not enough to reduce the digital carbon footprint so that it is no longer a threat to the environment.

Each of us should do our part to reduce our digital footprint, and spending less time online is one of the easiest ways to achieve this.

Unfortunately, many of us find it challenging to carry out this digital detox as our jobs, education, and socializing have largely moved into the digital world.

This is why it is necessary to implement sustainable practices into our daily use of the Internet, like deleting old emails as one way to reduce the storage of unnecessary data in data centers and thus our digital carbon footprint (something I will do as soon as I finish writing this blog).

Smart use of digital devices is another way to reduce electricity consumption, as well as recycling old devices or buying ones that are more energy efficient.

However, I don’t think we should feel guilty for deciding to unwind after a busy day with a good old social media scroll. We should be aware of the problem of digital carbon footprint, not to give up all the pleasures that the Internet provides but so that we can make smart decisions every day.

Solving environment-related problems and protecting the environment are still the top priorities and challenges for both people living in the Republic of Serbia and state institutions. In 2023, the Ministry of Environmental Protection, together with local governments and partners, worked on solving these problems, primarily those related to improving air quality, waste management, and protecting natural habitats.

The 2022-2023 Air Protection Program in the Republic of Serbia determined the total costs related to its implementation, which are approximately 2.6 billion euros. This program was adopted in December 2022, together with the Action Plan covering the period from 2022 to 2026. It will cost around 2.1 billion euros to implement.

In February 2023, the Ministry launched a competition to replace boilers and individual fire pits, while in September of the same year, it launched another public call for the replacement of boilers in heating plants and public institutions, to which it allocated additional financial resources. According to the Minister of Environmental Protection, Irena Vujović, a total of 27 cities and municipalities benefitted from the first tender. In contrast, funds for projects in 12 local governments were provided via the second tender.

“With the implementation of the projects from the second tender, coal and fuel oil boilers in 14 elementary schools, two preschools, two municipal administration buildings, three health centers and one cultural centre will be replaced by boilers that use more environmentally friendly energy sources“, specified the Minister.

IN FOCUS:

To improve air quality and combat climate change, on June 1, the Government adopted the  Low Carbon Development Strategy of the Republic of Serbia  for the period from 2023 to 2030 with projections until 2050. Adopting this Strategy is prescribed by the Law on Climate Change to determine strategic directions of action and public policies for reducing greenhouse gas emissions in the entire economy. In late 2023, the Government also adopted the Program for Adaptation to Changed Climate Conditions from 2023 to 2030, which prescribes the process of adaptation to such conditions systematically and based on scientifically based results on climate change in Serbia. The Program includes an analysis of eight-month climate changes and future climate change scenarios. The Action Plan covering the period from 2024 to 2026 was adopted under the Program’s auspices, which contains 25 measures, as well as the financial, institutional and time frame for their implementation and monitoring.

As another measure to improve air quality, the Government passed the Regulation on the subsidized purchase of electric and hybrid vehicles, and the Ministry subsequently allocated subsidies in March.

Unregulated landfills are a challenge and problem that people across Serbia live with daily. To solve this problem, 30 local governments proposed projects to prevent illegal waste dumping in 2023 and subsequently received funding. The action lasted until September 15, and as a result, more than 170 such locations were cleaned.

Also, in 2023, unsanitary landfills in Ruma, Požega and Zrenjanin were closed and rehabilitated.

In July, the contract for constructing the state-of-the-art regional waste management center called Eco Tamnava, located in the village of Kalenić in the Ub municipality, was signed, followed by construction in October. After the project is finished, the problem with waste management in 15 locations will be systematically solved. Transfer stations, recycling centers, a biological waste treatment plant, and other supporting infrastructure will be built as part of the project.

A vital planning document, the Sludge Management Programme in the Republic of Serbia, was adopted for the first time in Serbia last year. It covers the period from 2023 to 2032 and aims to establish a safe, sustainable, and cost-effective sludge management system for municipal wastewater treatment plants.

Regarding the construction of the missing sewage grid, relevant work was carried out last year in Niš, Pećinci, Gornji Milanovac, Boljevac and Raška. The construction of approximately 140 kilometers of the sewage grid is expected to be finished by the end of 2024 and 2025, respectively, depending on the location.

Latest analysis from SolarPower Europe reveals that, in 2023, Europe installed 17.2 GWh of new battery energy storage systems (BESS); a 94 per cent increase compared to 2022. This marks the third consecutive year of doubling the annual market.

By the end of 2023, Europe’s total operating BESS fleet reached around 36 GWh. The residential segment accounted for 63 per cent of this capacity, followed by large-scale battery systems (21 per cent), and commercial & industrial systems (nine per cent).

Germany led the market with 34 per cent of the European market share in 2023, followed by Italy (22 per cent), and the United Kingdom (15 per cent).

Although deployment is expected to continue to grow in 2024, projections still fall short of the estimated 200 GW of battery power capacity needed by 2030 to unlock the EU’s solar potential. Battery storage faces obstacles across Europe, including missing targets, insufficient market signals, double taxation, and restrictive grid policies for hybrid renewable installations.

More:

“Growing battery storage and flexibility represents a fundamental shift from our current grid-centric view of the market. It impacts not only the way we plan infrastructure and the way we operate the system, but also the markets we engage with. The new Electricity Market Design (EMD) legislation lays the groundwork for a more robust energy policy. We need to urgently implement these measures and call on the European Commission to report on the EMD implementation ahead of the first Energy Council in 2025”, said Walburga Hemetsberger, CEO of SolarPower Europe.

In tandem with solar PV, growth was predominantly propelled by home batteries. In the wake of the energy crisis, European citizens turned to batteries to build their energy self-sufficiency. The residential segment led deployment with 70 per cent of the annually installed BESS capacity, followed by large-scale battery systems at 21 per cent, and commercial & industrial systems at 9 per cent.

2023 marks the third consecutive year of doubling the annual market, with total battery storage capacity reaching 35.9 GWh by the end of 2023.

UNESCO Launches New Initiatives for “Greening Education”

On World Environment Day, UNESCO unveils new tools for greening schools and curricula, highlighting the need to empower young people to play a concrete role in tackling the climate crisis.

Greening schools and curricula is one of the best levers to tackle climate disruption in the long-term. It’s time to mainstream environmental education across school subjects, at all levels of education with an action-oriented approach that helps young people understand their power to make a difference.

A UNESCO analysis of 100 national curriculum frameworks in 2021 revealed that nearly half (47 per cent) do not mention climate disruption. Only 23 per cent of teachers felt able to properly address climate action in their classrooms and 70 per cent of  young people surveyed could not explain climate disruption, and expressed concerns about the way in which it is currently taught.

More:

Following this analysis, Audrey Azoulay, Director-General of UNESCO, made environmental education a priority in terms of the support which the Organization provides to its Member States. UNESCO has been leading the Greening Education Partnership, that more than 80 Member States have now joined and enables collaboration between more than 1,300 organizations, including UN agencies, civil society and youth organizations, as well as the private sector. This community provides countries with essential tools for strengthening the role of education in tackling climate disruption.

If significant progress has been made over the past three years by UNESCO Member States to integrate environmental topics across curricula, a new report co-published by the Organization cautions that formal education has focused too much on imparting knowledge about environmental issues, rather than driving action, and is failing to show learners the role they can play in tackling the climate crisis. The report argues that sustainable development education must also focus on first-hand experiences which are more likely to lead to change.
