Report: EU Renewables Beat Coal Power for the First Time

New EU renewables generation increased sharply in 2017, but the lion’s share of these gains were shouldered by the UK and Germany, demonstrating the “uneven” nature of energy sector decarbonisation across Europe.

That was the main conclusion of a new analysis by think tank Sandbag, which details how new wind, solar and biomass generation rose 12 per cent last year to overtake coal power generation for the first time across the EU.

The study said the performance underscored the “incredible progress” from five years’ ago when coal generation’s share of the power mix was twice that from the three main renewables technologies.

At the same time, however, renewables growth in the EU has become even more uneven, with the UK and Germany together contributing 56 per cent of clean power increases over the past three years.

Wind in particular has played a key role in the renewables’ upsurge, achieving a 19 per cent increase in electricity generation due to good wind conditions and “significant” investment in wind farms, the think tank explained. But despite its rapidly declining costs, new solar generation increased by a “surprisingly low” 14 per cent last year.

Overall, the UK alone increased its share of wind, solar, and biomass generation by 20 percentage points from eight per cent in 2010 to 28 per cent in 2017, an achievement only bettered by Denmark, which saw its renewables capacity surge from 32 per cent to 74 per cent over the same period.

And while Germany has also played a significant role in EU renewables growth in recent years, it did not manage the same speed of increase as the UK, with renewables expanding from 13 per cent in 2010 to 30 per cent in 2017

Dave Jones, report author and Sandbag’s European power and coal analyst, said the study gave a “very mixed picture” of the EU’s progress on renewables, and he called for a 35 per cent EU renewables target for 2030 – as the European Parliament recently backed – in order to hasten the phase out of coal power.

“EU renewables has been increasingly reliant on the success story of wind in Germany, the UK, and Denmark, which has been inspiring,” said Jones. “But other countries need to do more. Solar deployment is surprisingly low, and needs to respond to the massive falls in costs.”

The report also demonstrates the UK’s progress on energy efficiency, noting the UK reduced its electricity demand by two per cent last year – the only EU member to see its demand fall – while still growing its economy. Moreover, the UK has also sharply reduced the proportion of power derived from coal generation from 28 per cent in 2010 to seven per cent last year, according to the study.

In contrast, however, the EU as a whole saw its power consumption rise for the third year running, and while some countries in Western Europe are moving to phase out coal, Eastern Europe is generally struggling to do so. Overall, the report adds, emissions from the EU’s power sector remained unchanged last year.

Jones said countries needed to “reassess their efforts” on energy efficiency, and move faster to retire coal plants in order to meet climate targets. “We need a fast and complete coal phase-out in Europe: the thought of charging electric cars in the 2030’s with coal just doesn’t compute,” he said.

Also commenting on the study, ECIU analyst Dr Jonathan Marshall said the findings showed that gas was not needed in the move from coal to renewables, as increasing gas power capacity in the UK risks locking in high carbon infrastructure “for years to come”.

He also welcomed the UK’s progress on energy efficiency. “However, there remains a gap in efficiency policy looking ahead, with progress on low-carbon homes stalling and confusion over the future of appliance standards post-Brexit,” said Marshall. “By addressing these as soon as possible, the UK can ensure it remains at the front of the pack.”

It seems the deep decarbonisation of the power sector across the EU is technically and economically feasible, but only if leading countries remain fully committed to their renewables programmes and the rest of the bloc quickly follows suit.

Donald Trump Says US Could Re-enter Paris Climate Deal

Donald Trump has said the United States could re-enter the Paris climate change agreement – and that he would have taken a “tougher stand” in Brexit negotiations than Theresa May.

The US president said his country could join the international accord if it had a “completely different deal” but called the existing agreement a “terrible deal” and a “disaster” for the US.

The US president met with global condemnation when he announced in June 2017 that the US was pulling out of the climate agreement. The landmark treaty was signed by 195 nations after intense negotiations in 2015, with countries making voluntary pledges to cut carbon emissions in an attempt to restrict an increase in global temperatures to less than 2C this century.

Trump said in the ITV interview that he was a “believer in clean air and clean water” but the Paris agreement would have been a disaster for the US. However, despite initially saying he was “completely out” of the accord, Trump said there could be a way back for the US.

“First of all, it was a terrible deal for the US. If they made a good deal there’s always a chance we’d get back. But it was a terrible deal for the US. It was unfair to the US,” he said.

“I believe in clean air. I believe in crystal-clear, beautiful … I believe in just having good cleanliness in all. Now, with that being said, if somebody said go back into the Paris accord, it would have to be a completely different deal because we had a horrible deal.

“As usual, they took advantage of the US. We were in a terrible deal. Would I go back in? Yeah, I’d go back in. I like, as you know, I like Emmanuel [Macron]. I would love to, but it’s got to be a good deal for the US.”

Asked if he believed in climate change, Trump said: “There is a cooling, and there’s a heating. I mean look, it used to not be climate change, it used to be global warming. That wasn’t working too well because it was getting too cold all over the place. The ice caps were going to melt, they were going to be gone by now, but now they’re setting records. They’re at a record level.”

The start of 2018 brought significantly positive developments for the Madrid-based Fotowatio Renewable Ventures, as it reported major developments from renewable energy markets in Mexico and Chile.

Chile recently held an auction for the supply of 2,200 gigawatt-hours (GWh) of electricity from renewable energy projects. Fotowatio secured rights to develop 25% of this capacity, or 540 GWh. The project is likely to have solar as well as wind energy technology, making it a hybrid renewable energy project.

The project is expected to be located in northern Chile and, once commissioned, will generate enough electricity to power 224,000 households and offset 221,400 tonnes of carbon dioxide emissions. This is the first project for FRV in Chile, which already has renewable energy assets in Brazil, Mexico and Uruguay.

The project will also be FRV’s first hybrid renewable energy project. The company already has substantial experience in the solar power technology and is now looking to diversify into wind energy development as well. “Solar and wind technologies have many similarities and a high degree of maturity, which is allowing us to lead the transition to clean energy throughout the world. At FRV, we understand wind power as the natural progression of our consolidated experience in the solar energy sector, and we will continue to bet on it,” Andrea Fontana, Managing Director of Wind Energy division of FRV noted.

FRV also reported that it reached financial closure for its first solar power project in Mexico. The company secured funding from KfW, Bancomext, and ING for the 342 MW (DC) Potosí Solar Farm. The company had secured this project in an auction held by the National Center for Energy Control (CENACE) in September 2016. The project has a power purchase agreement with CFE Suministro Basico.

Construction on the project is yet to begin, but it is expected to be operational by 2019. Once commissioned, the project is expected to fulfill power needs of 150,000 Mexican households and offset 600,000 tonnes of carbon dioxide emissions every year.

Fotowatio Renewable Ventures was founded in 2006 and attracted equity funding from the likes of General Electric Energy Financial Services (GE EFS) and Grupo Corporativo Landon. The company was acquired by Abdul Latif Jameel Global Energy DMCC in 2015. FRV currently operates projects in five continents.

ECOHEALTH – In which Way Have We Disturbed Balance in Nature?

Foto-ilustracija: Pixabay
Photo-illustration: Pixabay

The occurrence of a type of pollution entails the disturbance of the natural balance in other parts of the ecosystem, affecting all human beings, since pollution does not know national and regional borders, nor racial, gender, and class differences. Despite the availability of a large amount of data and information, we are often not sufficiently aware of the exposure to environmental hazards, or we are unable to measure the concentration of pollutants in real time, nor to evaluate their final health effects.

However, if EcoHealth is viewed as the overall result of evolution, the relationship of previous generations to the environment, current population health is also subject to change. It is necessary to work on the development of people’s awareness that any positive change in our daily activities contributes to the improvement of the situation and that after decades of permanent irresponsible behaviour towards nature and environment in which we live, we need time for the efforts invested to become visible.

In order to combat environmental impact, urban communities should be equipped with the necessary financial, scientific and technical means for anticipating, preventing and mitigating environmental impacts on human health. Creating conditions that favour EcoHealth is multisectoral responsibility. The community, as a primary public health actor, should take the lead in establishing partnerships between institutions such as the Public Health Institute and Environmental Protection Agency, the civil sector, and be the leading promoter of EcoHealth among the population, as it is a key criterion of sustainable development.

WASTE

Photo-illustration: Pixabay

According to estimates, between 6 and 9 percent of municipal solid waste is recycled, and the composition of the waste deposited in landfills is diversified, which additionally increases its impacts on health and the environment.

Waste of organic origin makes the substances prone to decomposition and decay − which generates waste gases (hydrogen sulphide, methane, and mercaptans), recognizable by their characteristic scents spreading from bins and containers. In this fraction of waste can be found causes of tuberculosis, hepatitis, typhus, paratyphoid and dysentery, staphylococci, streptococci and many other germs, as well as bacteria that persist in the garbage for a long time, because they are favourable to the poor base environment created by mixing with ash from the replace.

Inorganic components of municipal as well as industrial waste can contain various toxic substances (heavy metals, pesticides, phenols, dioxins, etc.), which easily reach the soil and watercourses.

In populated areas without an adequately established waste management system, intestinal infections, infectious diseases, and parasites are more frequent. Garbage is the ideal environment for the reproduction of insects and rodents, carriers and agents of animal diseases, which are used in human nutrition.

Although medical waste accounts for about 20 percent of the total generated waste, due to the cause of infectious diseases and toxic substances it can contain, as well as resistant microorganisms, the importance of proper waste treatment is rapidly increasing. This waste can cause poisoning and lead to a series of injuries in people who come into contact with it in any way.

RADIOACTIVITY

Since the Republic of Serbia does not have any nuclear power plant, radioactivity is somewhat less considered as a factor of environmental pollution. But nuclear waste can transmit radioactivity up to 250 years after disposal, and take into account that there is not one designated landfill in Serbia, it is assumed that certain quantities of radioactive waste are inadequately disposed of. Radioactivity as a result of NATO bombing is a topic of numerous research in our country. In the wider public, the relationship between radioactivity and cancer is of great interest, because our country is at an insane second place in Europe in the number of malignant diseases.

Although this pollutant is often neglected, the impact of noise in urban areas is increasing. Its most common contaminants are traffic and industry, and it affects psychophysical health by causing nervousness, fatigue, insomnia and hearing impairment. Throughout Europe, prohibition of the broadcasting of loud music in the bars is being introduced, as well as sound isolation along the roads passing through settlements, and this practice is slowly being established in our country.

Springfield Properties Promises EV Charging as Standard for New Homes

Scottish housebuilder Springfield Homes has become one of the first firms in the UK to promise to include electric vehicle (EV) charging points in all its new developments.

Springfield announced late last week that 7kW cabling for EV charging will be installed as standard in all its new homes, starting with its £1bn, 3,000-home development Bertha Park in Perth.

Innes Smith, Springfield chief executive, said the company expected the widespread shift to eEVs would happen before 2032, when the Scottish government has promised to phase out the sale of all new petrol and diesel vehicles.

“One of our values as a company, is to include everything a customer needs in their new home, so, with this is mind, we wanted to make it as easy as possible for our customers to go electric,” Smith added.

The move makes Springfield Properties one of the first developers in the UK to incorporate EV charging as standard in all its new-build homes. The firm already offers solar panels as an “optional extra” for homeowners.

Scotland’s transport minister Humza Yousaf said the installations of charging points will help reduce barriers to EV ownership.

“With Scotland already leading the way with sales of electric and alternative fuelled vehicles rising faster than the rest of the UK, this is another positive step by industry in support of our vision to phase out the need for new petrol and diesel cars and vans by 2032,” he added.

Danish offshore wind company Ørsted has begun construction on the 1.2 gigawatt Hornsea Project One offshore wind farm which, upon completion, will be the largest offshore wind farm in the world.

Late last week, Ørsted — formerly DONG Energy — announced that the first of 174 monopiles had been installed 120 kilometers off the coast of Yorkshire, England, measuring 65 meters long and weighing approximately 800 tonnes. When complete in 2020, the Hornsea Project One offshore wind farm will amount to 1.2 GW (gigawatts) and will generate enough electricity to provide for the equivalent of 1 million UK homes.

“After years of planning it is fantastic to see the initial stages of offshore construction begin. My thanks to the teams working day and night on this significant milestone,” said Duncan Clark, programme director for the project.

“Onshore, we are continuing to construct the East Coast Hub which will serve as an operations and maintenance base for our existing wind farms in the area and both Hornsea Project One, and Project Two which we took a final investment decision on last year. These wind farms will not only greatly contribute to the UK’s goal of decarbonising our energy system, they are also bringing jobs and investment to Grimsby and the North East.”

The monopiles are being installed by offshore marine engineering company GeoSea, using the installation vessel Innovation, which is able to carry four monopiles at a time. Innovation will complete the installation of all the monopiles, and then begin work on installing some of the transition pieces, and will be joined in March by offshore wind farm installation company A2Sea’s vessel Sea Installer. Back in July of 2017, GeoSea acquired full ownership of A2Sea from DONG Energy and Siemens.

Innovation is a self-elevating vessel which can extend four legs down to the ocean floor and jack itself up to act as a stationary offshore installation platform. The vessel has a capacity of 31,400 tonnes and can accommodate 100 people onboard.

Global Solar To Hit 106 Gigawatts Of New Installations In 2018, Predicts EnergyTrend

Photo: Pixabay
Photo-illustration: Pixabay

EnergyTrend, a division of TrendForce, has predicted that strong momentum in China and rebounding demand in Europe will push the global solar market to install 106 gigawatts in 2018.

According to EnergyTrend’s latest report, both China and Europe will help push the global solar market along steady growth patterns in 2018, continuing a record-breaking year of solar installations in 2017. China officially installed a total of 52.83 GW (gigawatts) worth of solar in 2017, breaking all records as well as analyst predictions. We don’t have confirmed figures for total solar in 2017, but EnergyTrend expects it will reach over 100 GW for the first time (as does most everyone). EnergyTrend is reporting, however, that in addition to China’s 52.83 GW, the United States installed 12 GW, India 9.26 GW GW, and Japan 6.09.

Looking forward, EnergyTrend expects that solar will again tip the 100 GW mark and top out at around 106 GW, again being driven by “explosive demand in China.”

EnergyTrend expects that the Chinese solar market will be driven primarily by supportive policy and production capacity expansion. Specifically, Feed-in Tariff (FiT) adjustments expected this year will constrict ground-mounted solar PV, allowing distributed solar and Poverty Alleviation projects more room to grow. Adjustments to the FiT will result in two installation rushes by June 30th and December 30th in 2018 in an effort to apply for higher subsidies.

Interestingly, EnergyTrend analyst Rhea Tsao expects that China’s solar market will actually slow a little between 2018 and 2020, but this will be offset globally by a rebound in the European market which will emerge as one of the leading drivers of growth in 2018 and beyond, helping to keep the global market around the 100 GW mark. EnergyTrend points to large-scale ground-mounted power plants expected in France, the Netherlands, and Spain by the end of this year, and the end of the EU Minimal Import Price (MIP) measurement, “making Europe a highly competitive market.”

The world can expect more record-breaking bids for solar and wind energy projects this year as Saudi Arabia plans to hold at least two rounds of auction for solar and wind energy projects under its National Renewable Energy Program (NREP).

Saudi Arabia’s Renewable Energy Project Development Office (REPDO) recently announced plans to auction off 3.25 gigawatts of solar power and 800 megawatts of wind energy capacity this year.

The allocation of projects will be spread over two auction rounds. The first auction, planned in the first quarter, will feature 250 megawatts of solar power capacity. The second auction will see 3 gigawatts of solar power and 800 megawatts of wind energy capacity allocated.

Saudi Arabia issued tenders for 400 megawatts of wind energy and 300 megawatts of solar power capacity last year and attracted highly competitive bids. 25 companies qualified for the wind energy project planned in the Al Jouf region. Masdar, EDF, Acciona, GE, Enel, ENGIE, Marubeni, Siemens, ACWA Power, Vestas, and Goldwind are some of the heavyweights that submitted bids in the wind energy tender.

REPDO shortlisted bids from 27 companies for the solar power project in April last year. Subsequently, it trimmed the list to just 8 companies by October. This list included the Masdar Group, which quoted the world’s lowest-ever solar power tariff of ¢1.78/kWh. However, only two companies made it to the final round of selection — ACWA Power and Marubeni Corporation, along with their partner companies in project development.

The solar and wind energy projects offered last year, and the projects to be auction in this year’s auctions, are expected to be commissioned by 2020 as Saudi Arabia has set a target to have 3.45 gigawatts of renewable energy by that time. The country also has a 2030 target to have 9.5 gigawatts renewable energy capacity.

German Luxury Carmakers May Be Looking to Reverse Engineer Tesla’s Model 3

According to a report from Fred Lambert at Electrek, a pair of Tesla Model 3 vehicles have been spotted heading toward Germany, where a team from the competition may attempt to reverse engineer them. While Tesla has certainly struggled to meet the astronomical demand for their latest release, reviews have been lauding the company’s offering, going as far as to say that “the Model 3 has no competition.”

It looks as if some German carmakers are trying to change that.

Pictures of the cars were discovered on Facebook with the hashtag “Leipzig,” possibly indicating that the vehicles are headed to BMW. The luxury carmaker is slated to have an electric vehicle to rival Tesla’s that will be available in the near future. Sleuths also noticed a delivery sticker that could also indicate a stop in Stuttgart, the home of Mercedes-Benz and Porsche.

As of this writing, Tesla CEO Elon Musk has made no public statement on whether foreign competitors are trying to reverse engineer his products, and perhaps for good reason. He certainly is a busy man.

Musk’s companies are doing their best to completely disrupt the fields in which they are situated. SpaceX is shaping the future of the spaceflight industry in much the same way that Tesla is dictating what the electric vehicle landscape could look like in the years to come. It’d be no surprise if the competition is eager to see how Tesla works its magic.

While it is clear that Tesla has earned its spot as an industry leader, the emergence of greater numbers of competitors will push the company toward even greater heights. When the Tesla can no longer focus on pioneering tech, perfecting it will become the new name of the game.

We will likely see a lot more disruption from Tesla as it continues to unveil new technologies and prepare the world for the next era of transportation. Competitors are aware that they are behind the curve, and the path toward catching up could make this new era all the richer.

2017 Was the Hottest Year on Record for Oceans

Photo-illustration: Pixabay
Photo-illustration: Pixabay

Last year wasn’t just one of the hottest years on Earth’s surface, as it was the hottest year on record for the global ocean, according to a new study from the Institute of Atmospheric Physics (IAP)/Chinese Academy of Science.

Researchers Lijing Cheng and Jiang Zhu found that the top 2,000 meters of ocean waters are hotter than ever recorded, at 19.19 × 10^22 J. Heat energy is measured in Joules (J).

That’s quite the jump from 2015, the previous record-breaking year for ocean heat, which was recorded at 17.68 × 10^22 J.

“For comparison,” the study states, “total electricity generation in China in 2016 was 0.00216 × 10^22 J, which is 699 times smaller than the increase in ocean heat in 2017.”

Ocean heat in 2016 was cooler than both 2015 and 2017 due to a large El Ninõ event that year, which takes heat out of the ocean. As thermal sciences professor Dr. John Abraham explained in the Guardian, “During an El Niño, the Pacific Ocean tends to have very warm waters at the surface, which causes heat loss to the atmosphere (so the ocean cools and the atmosphere warms). Conversely, during a La Niña, the reverse process occurs.”

Despite the 2016 drop, the last five years were still the five warmest years in the ocean on record.

The study, published Friday in the journal Advances in Atmospheric Sciences, determined that the increase in ocean heat content for 2017 occurred in most regions of the world, with the Atlantic and Southern oceans showing more warming than Pacific and Indian oceans.

The research highlights how measuring ocean heat is key to tracking the impacts of climate change:

“Owing to its large heat capacity, the ocean accumulates the warming derived from human activities; indeed, more than 90 percent of Earth’s residual heat related to global warming is absorbed by the ocean. As such, the global ocean heat content record robustly represents the signature of global warming and is impacted less by weather-related noise and climate variability such as El Niño and La Niña events. The year 2016 was cooler than both 2015 and 2017 owing to the huge El Niño, which took some of the heat out of the ocean. According to the IAP ocean analysis, the last five years have been the five warmest years in the ocean.

Measurements of ocean heating are a more reliable indicator than atmospheric measurements for tracking the vital signs of the health of the planet.”

Abraham, who was not involved in the study, described the findings as “truly astonishing” and noted that the consequences of ocean heating could include declining oxygen levels in the oceans, coral bleaching, and the melting of sea ice and ice shelves that cause sea level rise.

“The consequences of this year-after-year-after-year warming have real impacts on humans,” Abraham said. “Fortunately, we know why the oceans are warming (because of human greenhouse gases), and we can do something about it. We can take action to reduce the heating of our planet by using energy more wisely and increasing the use of clean and renewable energy (like wind and solar power).”

The Chinese study underscores that how the oceans’ health—and the health of its creatures—are greatly impacted by human activities.

A separate paper published in Science this week showed that the millions of tons of plastic that we leach into our seas each year are literally poisoning and killing coral reefs.

“The likelihood of disease increases from 4 percent to 89 percent when corals are in contact with plastic,” the researchers reported.

The researchers estimated that more than 11 billion plastic items are currently littered in coral reefs in the Asia-Pacific region alone. If plastic consumption does not change, the total number could rise to 15.7 billion items by 2025.

“Plastic is one of the biggest threats in the ocean at the moment, I would say, apart from climate change,” Dr. Joleah Lamb of Cornell University said.

Macron: France Will Shut All Coal-Fired Power Stations by 2021

France will shut down all of its coal-fired power plants by 2021, President Emmanuel Macron announced at the World Economic Forum in Davos, Switzerland.

The deadline is two years ahead of his predecessor Francois Hollande’s goal of shutting down France’s coal-powered plants by 2023.

France only produces around 1 percent of its energy from coal-fired stations, as the country is 99 percent dependent on hydrocarbon imports. However, the move from the world’s fifth largest economy shows it is determined to be a leader on climate issues and sends a signal to other nations.

During his speech to politicians and business leaders on Wednesday, the French president said he wanted to “make France a model in the fight against climate change.”

Macron’s “Make Our Planet Great Again” program casts environmental protection as a pillar in reforming the country’s economy.

“That is a huge advantage in terms of attractiveness and competitiveness,” he said. “Talent will come where it is good to live. We can create a lot of jobs with such a strategy.”

Last month, the French parliament passed a law banning the exploration and production of all oil and natural gas by 2040 within mainland France and all overseas territories. France also plans to ban the sale of diesel and petrol engine cars by 2040.

At Davos, Macron stressed that warming needs to be kept within the 2 degrees Celsius limit set at the Paris climate agreement.

“On climate change, we’re losing the battle,” he said, adding that the world needs concrete action and results by 2020.

Macron’s climate policies are in stark contrast to President Donald Trump’s push for fossil fuels.

Scientists Investigated Wind Farm Noise For 3 Years. Here’s What They Found

Photo-illustration: Pixabay

Scientists in Germany have been studying the effects of wind farm noise on nearby residents and have discovered that not everyone is annoyed by the wind farms, but that those who are can sometimes bring the problem on by themselves with critical attitudes towards the wind farm.

Environmental psychologists at Martin Luther University Halle-Wittenberg (MLU) in Germany, working with UL DEWI (UL International GmbH), investigated a wind farm and nearby residents in northern Germany from 2012 to 2014. Nearly a third of residents reported no annoyance or only slight annoyance at the noise of the wind turbines, and only one in ten people experienced symptoms of stress as a result of the nearby wind farm — symptoms such as irritability or difficulty falling asleep.

The fascinating part of this study, however, was the width and breadth of the aspects of wind farm noise that they investigated.

For example, the environmental psychologists discovered that having an existing critical attitude toward a wind farm can stimulate the experience of stress. According to the study, nearly 10% of nearby residents surveyed experienced symptoms of stress at least once a month. “Symptoms include problems falling asleep, disturbed sleep in general, a negative mood, and strong irritability,” explained Dr Johannes Pohl from MLU.

Conversely, nearly 16% of those surveyed said they suffered similar symptoms as a result of road noise. Interestingly, when psychologists re-surveyed nearby residents two years later, those suffering from at least one symptom of stress had fallen to only 6.8%.

“Many residents get used to the noise from the wind farm or they have resigned themselves to it,” added Pohl. “A good one-fourth of those affected close their windows at night so that they are no longer disturbed by the noise,”

Further, those who showed the most signs of stress at the wind farm were those who already had a very critical attitude towards the wind farm and showed very little desire to learn how to cope with the stress.

Another interesting discovery was that the weather impacts the noise from the turbines — and not by making them go faster. When it is more humid or when there is frost, the noise from the wind turbines is more perceptible. “The wind and the movement of the rotor blades can cause amplitude modulation, in other words an irregular pulsating of the volume,” said Pohl. “These irregularities are what annoy some of the residents, something which they perceive to be irregular humming or swooshing.”

The study also determined that the best way to prevent future such issues was to address residents’ concerns and problems during the planning phase of wind farm development. “The way the residents experience the planning and construction phase is a decisive indicator of how strongly or weakly they will be impaired in the long run by the wind farm,” Pohl concluded.

EIA Expects Wind Energy To Surpass Hydro In 2019

Photo-illustration: Pixabay

The US Energy Information Administration has this week predicted that electricity generated from wind energy will surpass that from hydroelectricity, the previously-dominant renewable energy source in the US.

According to the latest Short-Term Energy Outlook published this week by the Energy Information Administration (EIA), this is due to a lack of new hydro plants coming online in the next two years plus continued wind installations. Specifically, the EIA explains that increases in hydroelectric generation in 2018 and 2019 will largely rely on precipitation and water runoff, and although weather patterns will also affect wind electricity generation, the EIA’s forecast for wind is more dependent on the capacity and timing of new wind farms coming online.

Both technologies will follow natural seasonal patterns — hydropower will peak in spring when precipitation and snowpack melt increases water runoff, while wind energy will peak in spring and fall. For hydropower specifically, the EIA expects hydropower generation to be down slightly in 2018 and 2019 after a relatively wet 2017. In 2017, hydropower provided 7.4% of total utility-scale generation, but that figure will drop in 2018 to 6.5%, and 6.6% in 2019.

Conversely, the EIA expects continued new wind capacity to come online during 2018 and 2019, with 8.3 GW (gigawatts) added in 2018 and 8 GW added in 2019, which will increase wind’s contribution to the utility-scale energy mix by 9% by the end of 2018 and by 8% by the end of 2019. In the end, the EIA expects wind to account for 6.4% of total utility-scale generation in 2018, and 6.9% in 2019, the point at which it exceeds hydropower.

San Diego Padres Building MLB’s Largest Solar Power System

 

The San Diego Padres are building the largest solar plant in all of Major League Baseball (MLB).

According to CNBC.com, Petco Park, the Padres home stadium, will build a 336,520 watt system. The plant will be formed from 716 high efficiency 470W SunPower modules, CNBC added. Sullivan Solar Power will build the system, which is expected to be completed in March, ahead of the 2018 MLB season. The system will generate more than 12 million kilowatt-hours (kWh) over the next 25 years.

Currently, the top five solar-powered MLB ballparks include AT&T Park (San Franciso Giants) Chase Field (Arizona Diamondbacks), Safeco Field (Seattle Mariners), Kaufman Stadium (KC Royals), and Busch Stadium (St. Louis Cardinals), according to PV Magazine.

The project will cost $1 million. However, with tax credits and lower electricity costs thrown into the mix, its estimated the new solar farm will save $4.1 million overall according to SportTechie.com.

San Diego is targeting for 100% renewables by 2035, and with the Padres getting aboard the solar energy train, other companies could well be inspired to make the switch soon.

“We are leading by example for the country to see that solar power is the future, today. We are determined to be a leader in creating a clean energy future,” added San Diego Mayor Kevin Faulconer on the cities new high profiled solar farm.

President and Founder of Sullivan Solar Power Daniel Sullivan said in a statement that he is delighted to see the Padres moving toward solar, proving that the world does not need fossil fuels in powering its requirements.

“I founded Sullivan Solar Power 14 years ago to create a case study in San Diego, proving we have the technology, financing, and skill to fundamentally change the way we generate electricity — this project highlights that we are leading the solar energy revolution,” added Sullivan.

Professional sports have taken to more sustainable development efforts in recent years. From Green Super Bowls, solar-friendly World Cup venues, to the NHL’s release of its carbon neutral energy plan in 2014, It’s a trend which will continue to move forward with momentum.

Unilever has this week struck a partnership agreement with Indonesia’s state-owned palm oil plantation firm PT Perkebunan Nusantara (PTPN) that will see the two work together to support local mills and farmers in producing palm oil that aligns with zero deforestation standards.

The memorandum of understanding, which was announced yesterday, will help accelerate production standards in the country in accordance with NDPE policies – no deforestation, no development on peat, and no exploitation of people and communities.

As part of the partnership, Unilever will support PTPN’s mills and supplying farmer base in their efforts to obtain sustainability certification through a combination of resources, funding, and technical expertise. Unilever said it would help ensure farmers are better positioned to enter the palm oil supply chain and enable them to increase their productivity and yield.

Marc Engel, chief supply chain officer at Unilever, said the firm’s ambition was to make sustainable palm oil “mainstream”, having worked hard in recent years on developing its approach to the issue.

“We are involved in various partnerships to help smallholder farmers improve their yields while protecting the environment and local communities,” he said in a statement. “The MoU with PTPN is the first time we can apply the produce-protect model at scale – our partnership will have a positive impact in Indonesia from an environmental, social and economic perspective which makes it unique to the industry.”

PTPN said the agreement provided an important incentive for smallholder farmers to adopt sustainable agricultural practices, as it provided a strong business case for embracing environmentally friendly palm oil production.

Erwan Pelawi, operating managing director at PTPN’s holding company, explained that the firm had an extensive network of smallholder farmers, with 61 per cent of the area it manages made up of palm oil plantations.

“We are committed to continuing sustainable palm oil management,” Pelawi said. “The MoU with Unilever is expected to improve the quality of how smallholder farmers manage palm oil cultivation and will also accelerate the process of sustainable palm oil certification which will in turn provide better benefits for the welfare of oil palm farmers in Indonesia.”

Separately yesterday, Unilever joined 60 other international companies including Tesco, McDonalds, and Marks & Spencer in signalling support for the ‘Cerrado Manifesto’ – a pledge to end the clearance of native vegetation in the Brazillian Cerrado region.

It also follows Unilever CEO Paul Polman’s call earlier this week for the wider global consumer goods industry to take more concerted action to reduce plastic packaging waste, an issue over which he said the sector was at a “critical juncture”.

Cal Poly, part of the California State University system, has this week dedicated a 4.5 megawatt solar farm that will serve to provide 25% of the university’s electricity needs, result in millions worth of savings, and provide on-site experience for its students.

The new 4.5 MW (megawatt) single-axis solar farm was dedicated on Wednesday at a ceremony at the 18.5-acre site, which is made up of over 16,000 solar panels that will generate more than 11 million kWh per year, enough to provide the equivalent electricity necessary to power more than 1,000 homes, but which will actually serve approximately 25% of Cal Poly’s needs.

Cal Poly is a nationally ranked, four-year, comprehensive polytechnic public university located in San Luis Obispo, California, and has made a name for itself through its Learn by Doing approach to study. With the advent of its new solar farm, students will now be able to experience hands-on experience with the solar farm. The university also designed a solar engineering and microgrid laboratory in the Electric Engineering building so that students can conduct experiments with solar technology.

“We applaud Cal Poly’s creativity in leveraging the system to inspire research in sustainability for years to come,” said Matt Walz, CEO of REC Solar, which was contracted to design, construct, and maintain the solar facility. “REC Solar is privileged to be a part of the university’s sustainability journey.”

REC Solar is a Duke Energy-owned company and leading provider of solar solutions for educational institutions and has more than 100 completed solar projects that together generate more than 30 MW. To bring the whole thing full circle, REC Solar was also founded by Cal Poly graduates. The company is also partnering with Cal Poly to provide funds for students and faculty involvement in the project, design a curriculum that meets Cal Poly’s sustainability learning objectives and serves to educate further renewable energy professionals, and will also be collaborating on applied research.

“This is a huge step toward our goal of climate neutrality, and we are very excited about using this new facility to support students’ hands-on learning,” said Dennis Elliot, the university’s director of energy, utilities and sustainability.
