Rio 2016 Reveals Olympic Medals, Celebrating Nature and Sustainability

u_vlupbP

With 52 days until the world’s best athletes go into battle in the Olympic Games, Rio 2016 and the Brazilian Mint have unveiled the medals they will be competing with each other to win.

International Olympic Committee (IOC) president Thomas Bach, who was present at the launch event in Barra Olympic Park, said: “Today marks the start of the final countdown to the first Olympic Games to be staged in South America.”

Bearing a design that celebrates the relationship between the strengths of Olympic heroes and the forces of nature, the 500g gold, silver and bronze medals have been made with sustainability at their heart.

The athletes who top the podium in Rio will receive medals made from gold that has been extracted without the use of mercury and which was produced according to strict sustainability criteria, from the initial mining all the way through to the design of the end product.

The silver and bronze medals have been produced using 30 per cent recycled materials. Half of the plastic in the ribbons which will be used to hang the medals around athletes’ necks comes from recycled plastic bottles. The rounded cases that hold the medals were made from freijó wood certified by the Forest Stewardship Council (FSC).

A total of 2,488 medals have been produced: 812 gold, 812 silver and 864 bronze.

For the first time, the medals are slightly thicker at their central point compared with their edges. The name of the event for which the medal was won is engraved by laser along the outside edge.

The designs feature laurel leaves – a symbol of victory in ancient Greece, in the form of the wreaths awarded to competition winners – surrounding the Rio 2016 Olympic logo. The laurel leaves represent the link between the force of nature and Olympians.

According to Olympic Games tradition, the other side of the medals features an image of Nike, the Greek goddess of victory with the Panathinaiko Stadium and the Acropolis in the background.

The Paralympic Games medals, which feature a special innovation, have also been revealed. They have a tiny device inside which makes a noise when the medal is shaken, allowing visually impaired athletes to know if they are gold, silver or bronze (gold has the loudest noise, bronze the quietest).

Also revealed at the event on Tuesday (14 June) at the Future Arena, were the podiums (above), which are made from organic materials and celebrate the tropical nature of Brazil. The podiums have been designed to be reused as furniture after the Games. Also in line with Rio 2016’s commitment to sustainability, the medal trays that the presenters will use are made of certified Curupixá wood.

The uniforms that will be worn by the medal presenters were also unveiled at the event. Inspired by the natural beauty of Rio and by Brazilian culture and fashion, the uniforms were designed by Rio-based stylist Andrea Marques, who won a competition curated by Paulo Borges, the creative director of São Paulo Fashion Week.

“The main idea is that the clothes portray Rio de Janeiro as a welcoming city,” said Marques.

The American Highway: a New Source of Solar Energy

Route 66 crosses 3,940 km of the continental USA, stretching from California to Illinois, and for one ambitious startup, this famous road is an ideal source of clean energy.

Based in Idaho, Solar Roadways was founded in 2006 by husband and wife team Julie and Scott Brusaw, who have spent more than a decade working on technology that replaces traditional carriageway surfaces with solar panels.

Their project involves paving a section of the highway, once dubbed ‘the main street of America’, with these large, thick hexagon-shaped installations, built to hold up under all weather, and strong enough to handle a load capacity of 110,000 kg.

Amongst the solar panels’ innovative features is their capability to heat a road to keep its surface free of ice and snow.

The location for the initiative is near the Route 66 Welcome Centre in Conway, Missouri and the project is supported by the state’s Department of Transportation.

Solar Roadways believe their technology is sturdy, durable, efficient, and they foresee the application as a smart grid (an electricity supply network that can sensor usage and respond to needs as required).

Built to last an estimated 20 years, the panels are intended to duplicate the performance characteristics of highway asphalt, concerning being able to maintain traction for any number of vehicles and sustain high-impact incidence.

Prototype panels have the texture to stop a vehicle travelling at 129 kms an hour on a wet surface within an acceptable distance. Unlike asphalt or bitumen, the panels do not soften under high temperature.

The Brusaws are convinced that Solar Roadways is the ideal solution to the energy needs of the USA. If rolled out across the country in all possible configurations from roads to exterior parking lots, they believe that the panels would create 13,385 billion kWh of electricity – far more than the country uses in a year.

Estimates of how much energy a single panel generates is contingent on a number of factors including the season of the year, actual geographic location, and microclimatic factors.

The stakeholders hope to realise funding of the project with a combination of government grants and crowdsourcing.

The technology, which has been criticised as expensive and a poor performer compared to other solar technologies, has a brief but notable recent history.

In 2014, a 70 metre ‘solar’ bike path became operable in The Netherlands and reports indicate that it has successfully generated 3,000 kWh in six months.

In February, the French government announced a plan to power street lighting for a township 5,000 using solar panel paving technology laid out over 1 km of road.

This would be the pilot project that would ultimately see 1,000 km of the country’s roads using the technology over the next five years.

This Farm of the Future Uses No Soil and 95% Less Water

index

There’s a revolution happening in the way food is grown around the world. Vertical farming stacks crops on top of one another in a climate controlled, indoor facility, and utilizes advanced technology to produce food in the most environmentally friendly way the world has ever seen.

At AeroFarms in Newark, New Jersey, crops are stacked more than 30 feet high in a 30,000 square foot space that was formerly a laser tag arena. They use aeroponic technology, which involves misting the roots of the plants, using an astonishing 95% less water than more conventional farming methods. David Rosenberg, CEO of AeroFarms told Seeker, “Typically, in indoor growing, the roots sit in water, and one tries to oxygenate the water. Our key inventor realized that if we mist nutrition to the root structure, then the roots have a better oxygenation.”

AeroFarms doesn’t use any pesticides or herbicides either. The plants are grown in a reusable cloth made from recycled plastic, so no soil is needed to grow them. They also use a system of specialized LED lighting instead of natural sunlight, reducing their energy footprint even further. “A lot of people say ‘Sunless? Wait. Plants need sun.’ In fact the plants don’t need yellow spectrum. So we’re able to reduce our energy footprint by doing things like reducing certain types of spectrum,” Rosenberg said.

Dickson Despommier, an ecologist from Columbia University, was one of the first advocates of vertical farming. In 1999, he proposed that vertical farming could help feed our ever-growing, overpopulated cities, while using less water than current farming methods and reducing the need to transport food long-distances. Despommier likely never imagined his idea would be taking shape on a global level, just 17 years later.

There are now vertical farms in Canada, Panama, the U.K. and all around the U.S. AeroFarms is currently building another vertical farm facility in an old steel mill that’s larger than a football field. They expect it will grow up to 2 million pounds of greens every year.
Rosenberg believes that vertical farming is truly the way of the future. “It’s a tough business, but it’s one that’s going to stay and it’s going to have a bigger and bigger impact.”

If You’re After Off-Grid Luxury, this New Houseboat May Float Your Boat

waterlovt-houseboat-8

A new floating home combines the United Arab Emirates’ (UAE’s) penchant for the finer things in life with Dutch maritime engineering expertise. The Waterlovt is aimed at providing its owners with all the bells and whistles of a luxury apartment, the serenity and freedom of a waterborne lifestyle and the autonomy of off-grid living.

The idea for the Waterlovt was conceived just over a year ago by Dutch entrepreneur Berend Lens van Rijn while he was was in the costly process of finding an apartment to rent. “That was when I started thinking about luxury living on the water and also when I decided to introduce this idea in Abu Dhabi,” explains Lens van Rijn.

Lens van Rijn describes the Waterlovt as “taking the concept of a houseboat to a whole new level” and says it is designed to change how people can live on the water. There’s no engine on board, so it needs to be towed into position, but it’s unlikely these are the sort of digs you’re going to want to be moving around a great deal. As well as providing plush living quarters, the Waterlovt is built with circular principles in mind, using modular components and natural materials that can be easily recycled, and can be kitted out to operate entirely self sufficiently.

The craft is based on a barge structure and can be tailored to the requirements and desires of the customer. To begin, there there are four variants. The Waterlovt 90 measures 22 x 8.9 m (72 x 29 ft) and has an internal area of 90 sq m (969 sq ft), accommodating two bedrooms. The Waterlovt 120 also houses two bedrooms, but is a little larger at 26.8 x 8.9 m (88 x 29 ft) and with 120 sq m (1,292 sq ft) of internal space.

Different solar power systems can be installed, depending on what is required. These include a system that allows the Waterlovt to be off-grid during the day only, or a system with battery packs and a stand-by whisper generator that allows for fully self-sufficient 24-hour operation. All the units are supplied with a connection that allows them to be hooked up to a mainland power supply.

The off-grid credentials of the Waterlovt can be furthered with a desalination system that processes seawater using double-membrane reverse osmosis and ultraviolet sterilization to make it safe to drink. The system can produce 30 l (6.6 gal) of drinkable water an hour and has a storage capacity of 300 l (66 gal). In addition, a sewage treatment unit can be installed to make wastewater safe to discharge into open water, and a digester can be installed to generate power using organic waste.

There are a variety of features that are aimed at helping to keep the Waterlovt temperate, including smart glass that darkens in sunlight, air conditioning that is adapted for the area in which the Waterlovt will be located and designed to work optimally in combination with solar power and battery packs, and a floor with ventilation and heat ducts that provide cooling and heating capabilities.

Lighting controls and a power supply monitor are also installed, with additional home automation features able to be added as required. Entertainment systems including home cinema, satellite TV and audio systems with streaming music services can be customized and fitted as the customer requires.

The Waterlovts are said to be manufactured to the highest industry safety standards for houseboats in the Netherlands. Safety features include automatic leak detection that is linked to the pumps and detection alarms for smoke and carbon monoxide.

Towards Clean and Smart Mobility

image_xlarge

Transport plays a critical role in the way we live. Our food, clothes and household waste all need to be transported, contributing to our economy and quality of life. But the increasing use of planes, cars and other fossil-fuel dependent modes of transport is causing more pollution, putting at risk our environment and health. The European Environment Agency’s (EEA) Signals 2016 explores how Europe’s carbon-dependent transport sector can be turned into a clean and smart mobility system.

EEA Signals 2016 – Towards green and smart mobility goes beyond the data and statistics on transport, giving an in-depth explanation of the key facts and trends, the environmental challenges facing transport, and the green choices we have to ensure cleaner modes of moving around.

Transport underpins our modern society and economy. At the same time, it is responsible for a quarter of the EU’s greenhouse gas emissions, and causes air pollution, noise pollution and habitat fragmentation.

The European Union has already taken measures to mitigate the effects of transport pollution, and it has launched work on ambitious plans to create a low-carbon economy by 2050. These plans include making sure transport plays its part in reducing emissions.

“The EU’s transport sector depends on oil for 94 % of its fuel. It is clear that decarbonising Europe’s transport sector will take time. It requires a combination of measures, including better urban planning, technological improvements, and a wider use of alternative fuels. But it can be done and we know how we can make it happen. Cleaner and smarter transport can actually meet Europe’s need for mobility and at the same time deliver many public health benefits, including cleaner air, fewer accidents, less congestion and less noise pollution,” says EEA Executive Director Hans Bruyninckx.

Signals 2016 includes articles focusing on the state of Europe’s transport sector, its impact on public health, the issue of food miles, aviation and shipping, plus an interview on how cities can plan for smart mobility and climate change.

The EEA publishes Signals annually in an easy-to-read format exploring key issues of interest to the environmental debate and the wider public.

Renewable Energy in Eastern Ukraine: For the children of the Town of Bryanka, the answer was blowing in the wind

Photo-illustration: Pixabay

Power outages are common in rural areas of Eastern Ukraine partly due to the worn out power lines infrastructure and also because of harsh weather conditions in the winter and autumn. For a hospital power outages are not just a matter of inconvenience. The lack of a reliable energy supply can and does have a drastic impact on a doctor’s ability to save children’s lives.

Years of mining have turned the town of Bryanka in Eastern Ukraine into an environmental hotspot leaving a heavy footprint not only on the environment through increased greenhouse gas emissions and local air, water, and land pollution but also negatively impacting people’s lives. Coal dust stirred during the mining process and from transport of coal can cause severe respiratory problems to people and in some extreme cases can even lead to death. The recent economic crisis has affected Ukraine more strongly than other countries and it aggravates the situation. High levels of unemployment, low incomes, decreased life expectancy, and the growth of infant mortality rate and proliferation of communicable diseases are just a few challenges that Bryanka residents face as a result. Women and children are particularly prone to suffer from negative health due to living in areas affected by mining.

There was an urgent need for solution to the problem of power outages at Bryanka children’s hospital. Since the hospital is a public organization it has been constantly underfunded meaning that the solution had to be cost-effective, environmentally-friendly and sustainable at the same time.

“We wanted to buy a diesel electric-power generator but had to give up this idea,” says Elena Zhevaga , the hospital’s supply manager. “This is a children’s hospital. We couldn’t have the constant smell and noise here. Besides, the exhaust from the diesel electric-power generator is harmful and it releases CO2 into the air – and we have enough of that anyway here,” she adds.

The environmental NGO “Zeleny Svit” (Green World) has turned to UNDP GEF Small Grants Programme for the solution to the problem of preventing power outages while at the same time providing a source of clean, affordable, and reliable energy for the hospital.

The solution was to power the hospital using wind energy. It was a joint decision of the hospital, the mayor’s office, and the NGO ‘Zeleny Svit’ to purchase and install a 5 KwH wind power generator capable of producing up to 5 KwH of energy, enough to keep the hospital running for 5 hours in the event of a power failure.

The Small Grants Programme supported the initiative with 50 000 USD because it was not only helping people of Bryanka but it was providing global environmental benefits by reducing carbon dioxide emissions through the use of wind energy. In the broader scheme of things, the Small Grants Programme project helped to raise people’s awareness about climate change and demonstrated local solutions for global challenges. The GEF Small Grant Programme has been deeply committed to promote environmental protection and support initiatives of non-governmental and community based organizations, demonstrating that community action can respond to people’s needs and promote global environmental benefits at the same time.

This grass-roots initiative was also supported by the Lugansk state environmental department because it contributed to local environmental strategies and demonstrated an integrated approach to ecology, economy and health care.

The solution to the environmental and economical problems at the Byyanka Children’s hospital was always there – blowing in the wind.

San Francisco Just Took a Huge Step Towards Becoming a Zero-Waste City

Photo: Pixabay
Photo: Pixabay

Back in 2002, San Francisco adopted a “Zero-Waste” scheme. The scheme hopes to make San Francisco the first city of its size to achieve zero waste by 2020. They’ve made some pretty huge steps so far: they created a public campaign pushing people to reduce their waste, to reuse what they consume, and to recycle and compost anything that is no longer usable. They banned the sale of plastic bottles on public property back in 2014. They added a cigarette tax that funds cigarette butt clean-up. They required supermarkets to charge for plastic bags. They made recycling and composting a requirement for residents. And they require new buildings to have water bottle-filling stations.

But the latest step may be the best and most ambitious: two weeks ago they banned the sale of styrofoam.

There are many cities which have already instituted restrictions on the use of polystyrene foam (known commonly by the brand name “Styrofoam,”) but San Francisco’s ban is the strictest yet.

Styrofoam is an effective food-storage material — it’s a good insulator, and it keeps food clean. But it takes centuries to break down in landfills, and while it can be recycled, facilities aren’t usually able to handle the sheer amount of it being used and discarded. And it’s a problem for marine life, too.

Allison Chan, a manager at the Save the Bay organization in Oakland, told the website TakePart: “The main challenge posed by Styrofoam is that it breaks into tiny little pieces, especially outside in the sun when it photodegrades. It looks more and more like food and makes [hungry predators who then eat the foam] feel full and really, they’re malnourished and they can die from that condition.”

Whether San Francisco meets its goal remains to be seen. The goal of zero-waste by 2020 was made intentionally difficult by the city, in order to give local legislators a sense of urgency. But regardless of whether the goal is met or not, it’s just another example of the world moving in the right direction when it comes to climate change: it comes on the heels of the landmark agreement between the US, Mexico, and Canada to get 50% of their energy from renewable resources by 2030, and a half a year after the first-of-its-kind worldwide climate agreement in Paris.

Plenty of other cities are making strides towards reducing their waste and becoming more sustainable, but it’s great to see the city by the Bay leading the way.

Tackling Plastic pollution Should Begin at the Source

mlvg

Marine Litter Vital Graphics, highlights why it is important to act now if we want to avoid living in a sea of plastic by mid-century. Though short-term fixes do exist, any lasting solution to the problem of plastic pollution must include tackling it as its source.

Marine Litter Vital Graphics, co-authored by the United Nationals Environment Programme (UNEP), and Grid Arendal underscores the need to take a hard look at how we produce and use plastic.

The world population in 1950 was 2.5 billion and global production of plastic was 1.5 million tonnes. Today there are more than 7 billion people in the world and plastic production exceeds 300 million tonnes annually. Marine Litter Vital Graphics report states that if the trend continues, by 2050 we will accumulate another 33 billion tonnes of plastic.

To adequately address this issue, we need “upstream” governance actions that can help reduce the amount of plastic that enters the environment. Recycling is one example, but that captures only a small portion of waste plastic. Other actions include putting in place financial disincentives to produce and use of plastic materials. Marine plastic pollution is already harming marine life and threatening biodiversity. There is an urgent need to reverse this trend to avoid further damage.

Marine Litter Vital Graphics follows a UNEP report that looked at how large plastic debris and “microplastics” are omnipresent from the Arctic to the Antarctic. It advocates for taking preventative action to safeguard our planet and oceans.

IHS Names SMA, SolarEdge, Schneider Electric, Sungrow, Huawei and ABB as Leaders in PV Inverter Supplier Scorecard

solar_sma_pv_inverter

SMA, SolarEdge, Schneider Electric, Sungrow, Huawei and ABB were all identified as solar photovoltaic (PV) inverter industry leaders with above average scores for both market presence and market momentum, according to an industry review scorecard from IHS Inc. (Englewood, CO, U.S.).

SMA Solar Technology AG (Niestetal, Germany) scored the highest on market presence, receiving maximum scores in nearly all categories, due to its complete product portfolio, strong position in all major regions, strong brand and continued position as the world’s largest supplier in revenue terms.

ABB and Sungrow also scored highly in market presence, recording consistently elevated scores for all categories.

“IHS has evaluated each of the biggest suppliers based on nine different metrics to arrive at overall scores for market presence and market momentum,” said Sam Wilkinson, senior manager, solar research at IHS Technology.

“This diverse group of companies has effectively overcome challenges, to position themselves at the forefront of the market.”

Among the solar PV inverter industry leaders, one of the highest scores for market momentum was awarded to Huawei, because of the speed it has gained global market share, and the high proportion of the company’s revenues that are spent on research and development.

Although it was not categorized as a leader due to a relatively low score for market presence, General Electric recorded the highest market momentum score – largely because of the rapid gains it has recently made in global market share and by securing a strong position in the North America utility-scale market.

Similarly, Enphase scored highly for market momentum, but its market presence score was restricted by its limited regional presence, a low score for financials, and its limited product portfolio, relative to other suppliers. Both companies were named within a group of “Challengers” in the scorecard report.

The IHS PV Inverter Supplier Scorecard addresses a need for a holistic review of the PV inverter supplier base – one that does not rely simply on megawatt or revenue market share, IHS notes.

The results reward companies that are well established in a wide range of markets, with strong brands and strong financial results, and that are well positioned for growth in the future.

A Thirst for Power: The Water-Energy Nexus

index

We all know that when you mix water and electricity, the results are shocking, but there’s an important connection between the two that goes beyond the potential for bathroom tragedy.

But here’s what’s really shocking: water and energy are connected and highly interdependent. Simply put, we need water for our energy systems and we need energy systems for our water. Here are some quick facts to prove it:
• Ninety percent of global electricity is generated by boiling water to create steam that spins turbines. It’s water-intense!
• In the United States, more freshwater (41 percent) is used to cool power plants than for any other use.
• About 8 percent of global energy generation is used for pumping, treating, and transporting water.
• By 2035, global energy consumption is expected to increase by 50 percent, increasing water consumption by 85 percent.

Natural gas, coal, crude oil, photovoltaics, wind – every type of energy requires a different amount of water to generate power. But here’s the thing: fossil fuel power plants are super thirsty. For example, according to the Union of Concerned Scientists, “a typical coal plant with a once-through cooling system withdraws between 70 and 180 billion gallons of water per year and consumes 0.36 to 1.1 billion gallons of that water.” To give some perspective, the water withdrawn is enough to fill between 105,991 and 272,549 Olympic-sized swimming pools – every year. And there are thousands of coal plants around the world.

By comparison, wind energy requires virtually no water to operate, and only minimal water for manufacturing and site development. In fact, a new report found that solar photovoltaic systems and wind turbines consume about 0.1 – 14 percent of the water (to generate 1 MWh) that a coal plant would over their respective lifetimes.

Renewable energy offers a double whammy of climate solutions. Reducing our dependence on dirty energy will significantly reduce the greenhouse gases we put into our atmosphere from the power sector. Clean energy technologies also tend to use a tiny fraction of the water dirty energy does – allowing us to better cope with climate impacts we’re already experiencing, like drought.

In fact, in 2014, wind energy alone saved drought-stricken California 2.5 billion gallons of water.

Another way to think about the energy impact of water is as its carbon footprint. Water supply and disposal systems require vast amounts of energy to operate, and most of our energy systems still rely on conventional dirty sources.

In fact, according to River Network, the carbon emissions generated from the energy needed to move, treat, and heat water in the US is about 290 million metric tons a year, or the combined annual greenhouse gas emissions of Alaska, Delaware, Hawaii, Idaho, Maine, Nebraska, Nevada, New Hampshire, Oregon, Rhode Island, and Vermont.

As we continue to move away from dirty fossil fuels, our water systems will become less and less carbon-intense. It’s a no-brainer: using less water and producing less carbon is better for our planet and for people.

Helping to Deliver Egypt’s Renewable Energy Vision

PV-755x336

Egypt has set ambitious targets for the roll-out and expansion of renewable generation and transmission infrastructure over the next few years. And ABB is in an excellent position to help the country achieve its ambitions to transform its energy market.

Over the past few years, Egypt has emerged as a regional leader in harnessing wind energy for electricity generation. This has been driven by a national strategy, initiated by Egypt’s New and Renewable Energy Authority (NREA) in February 2008, to diversify electricity generation, rationalize the use of energy and expand renewable energy sources. Renewable energy is seen as a key way of transforming the country’s key development pillars of power, health, infrastructure, education, and people.

The stated aim of the NREA strategy is to raise the contribution of renewable energy sources to 20 percent of total electricity generation by 2020. Of this, grid-connected wind power will account for some 12 percent of total electricity generation (7.2 GW total capacity), with hydropower and solar energy also providing significant contributions.

Demand for electricity is growing rapidly in Egypt; at an estimated additional 1,500 to 2,000 MW per year, as a result of rapid urbanization and economic growth. Recently, Egypt has suffered severe power shortages and rolling blackouts, so the need for alternative energy options is a pressing one.

However, there is a lot of work still to do to meet the 2020 renewable energy goal. Egypt’s total installed wind generation capacity at the end of 2015 was 810 MW or one percent of the country’s total electricity generation.

The country is recognized as having some of the world’s best wind resources, especially in the Gulf of Suez area and along the east and west banks of the Nile.

Egypt’s best-developed wind region so far is the Zafarana district, with average wind speeds of around nine meters a second.

As part of its drive to harness renewable energy sources, the NREA is also driving the unbundling and liberalization of Egypt’s energy market, and the transformation of the Egyptian Electricity Transmission Company (EECT) into an independent operator, with a massive program to expand and improve transmission infrastructure.

This and other aspects were recently discussed at the Roundtable, Egypt’s Renewables Strategy (hosted by Open Chance and Andrews Kurth in collaboration with NREA and organized by MEED – Middle East Business Intelligence) in which I participated in Cairo on May 31.

ABB stands ready to help the NREA and EECT to meet these ambitious targets, driven by local support from our entire organization. ABB is well positioned to support Egypt in the planning, development, construction and grid integration of wind power plants.

ABB is one of the few vendors that have been involved in the commercialization of wind power since its earliest days. As the largest supplier of electrical components, systems and services to the wind power industry, we have decades of experience and have installed more equipment in wind farms than any other supplier.

ABB’s capability runs right through the value chain, from consultancy at the very beginning of a project to create the optimum layout for a wind plant, through creating the ideal electrical drivetrain package for the wind turbines to controlling and automation the wind plant operation, collecting the power generated and integrating it into the local grid.

Solar Power Boosts Food Production & Fights Poverty

newsroom_solarpumping_2

We all know that solar power offers myriad health and environmental benefits over traditional energy sources — including reduced emissions and improved air quality — but the social benefits it offers are perhaps less well known. A new paper from IRENA, launched in June at InterSolar Europe in Munich, highlights the way solar technology is being used to power food production and empower communities to escape poverty.

For example, Solar Pumping for Irrigation: Improving livelihoods and sustainability, details how solar technology is being used to improve farming efficiency and agricultural output, highlighting successful examples from across Africa and Asia.

According to the United Nations, more than 40% of the world’s population makes a living in the agriculture sector — many of whom live in poverty. Socio-economic development is strongly linked to agricultural productivity, and as climate change continues to disrupt rainfall patterns, developing irrigation is becoming a vital tool to combat poverty. Given that only 5% of sub-Saharan African farmland irrigated, and that the continent is home to one of the fastest growing populations on the planet, the need to produce more food and energy is becoming critical.

Some countries are now exploring solar-based solutions (e.g. water pumps powered by solar panels), which provide reliable, cost-effective, and environmentally sustainable energy for decentralized irrigation services. These solutions are even cost-competitive with diesel powered pumps in many cases.

For example, Solar Pumping for Irrigation highlights a case in India, where diesel-powered water pumps on salt-pan farms were replaced with solar-powered pumps. The change resulted in a life-changing 161% increase in annual monetary savings for the farmers, in addition to reduced air pollution and CO2 emissions.

Solar-pumps and other solar technologies are proven to positively affect the lives of both men and women. For example, the installation of three solar-powered drip-irrigation systems in the Kalale district of northern Benin helped a co-operative of 35-45 women free themselves from four hours of labor a day. The increased time and more reliable income from the irrigation system, helps the women to feed, educate, and provide medical care for their families.

Water, energy, and food are intimately interlinked. Within this nexus, actions taken in any areas affects the others. In Solar Pumping for Irrigation, IRENA calls for a holistic approach with regards to policy, which recommends to:
• foster innovation and flexibility when delivering solar pumping solutions;
• take into account target groups and the long-term sustainability of markets when considering financial instruments to support solar pumping;
• focus on after-sales support and capacity building: providing support for regular operation and maintenance;
• package energy and water-efficient solutions in water-stressed areas;
• assess the direct and indirect impacts on water resources;
• monitor performance and gather data;
• consider the influence of availability and cost of energy on the choice of crops grown;
• and adopt an integrated approach to programme design: solar pumps can also bring electricity to poorly connected communities and contribute to the achievement of multiple Sustainable Development Goals.

World’s First 24/7 Solar Power Plant Powers 75,000 Homes

Photo: Pixabay
Photo: Pixabay

SolarReserve’s Crescent Dunes Project in Tonopah, Nevada is quietly providing clean, green solar energy to 75,000 homes in the Silver State even when the sun isn’t shining.

Crescent Dunes is the first utility-scale facility in the world to use molten salt for power energy storage capabilities, a technology also known as concentrated solar.

With a concentrated solar plant such as Crescent Dunes—including other plants like it around the world—more than 10,000 movable mirrors, or heliostats, reflect solar energy to a central, 640-foot tower that heats up salt to 1,050 degrees Fahrenheit.

This salt is used for two purposes, as SolarReserve points out on its website. First, it retains very high levels of heat, making it like a thermal battery that can be used night and day, whether or not the sun is out. Second, when electricity is needed on the grid, the molten salt gets dispatched through a heat exchanger to create super-heated steam to power a traditional steam turbine.

This process is similar to a conventional fossil fuel or nuclear power plant except with zero carbon emissions or hazardous waste and without any fuel costs, the California-based solar company says.

“The whole project cost slightly under $1 billion and SolarReserve holds a 25-year contract to supply power to NV Energy for $135 per megawatt hour,” OilPrice.com observed. “The tower produces 110 megawatts of energy for 12 hours a day according to the company, which works out to roughly 1 million megawatts per year. This in turn implies a gross [return on assets] of ~13.5 percent—not bad as investments go.”

The method is different compared to photovoltaic technology, which harnesses the sun’s rays on panels that convert sunlight into electricity. While photovoltaic arrays have many benefits and the technology has been well-tested and proven, its biggest problem is when the sun is not out.

As EcoWatch mentioned previously, a solar system’s peak generation hours do not coincide with the utility’s peak load hours after 5 p.m., meaning power companies turn to high-carbon peaking turbines in the evenings, thus decreasing the environmental benefits of solar panels.

“The plant is noteworthy for what it accomplishes—it is the first truly 24-7 solar plant in the world. For many applications that is a very big deal,” OilPrice.com adds about the Crescent Dunes project. “Having to build a second power plant to back up a solar array is not an ideal solution to say the least. Thermal solar resolves that issue all while letting facilities like SolarReserve’s store 1,100 megawatt-hours of energy.”

Residential or grid-scale battery systems, such as the ones manufactured by Tesla, are an another emerging solution to solar storage issues but the technology is relatively new.

Solar thermal plants are setting up in sun-spoiled deserts around the world. The Ivanpah Solar Electric Generating System in the California Mojave Desert is the largest concentrated solar plant in the U.S., spanning 3,500 acres and has 377 megawatts of net generating capacity. The facility, however, is experiencing widely reported “engineering hiccups,” including a fire that broke out in May.

Dubai’s massive Mohammed bin Rashid Al Maktoum Solar Park is another notable concentrated solar plant that will hold the distinction of being the world’s largest once it’s operational in April 2017. The facility aims to produce 1,000 megawatts by 2020 and 5,000 megawatts by 2030. The solar park also broke the record of having the world’s cheapest solar on May 1 when five international companies bid as little as 2.99 cents per kilowatt-hour to develop the plant’s latest phase of work.

Besides Crescent Dunes, SolarReserve is developing two other concentrated solar plants. The venture is building the Redstone Solar Thermal Power Project in the town of Postmasburg in South Africa, which will be the first concentrated solar plant in Africa. The other is the Copiapó Solar Energy Project in Chile which will combine both concentrated solar and photovoltaics, making it the first facility of its kind in the South American country.

Đukanović with KfW delegation: German bank said it would support road infrastructure

1_3

German Development Bank KfW invested resources that were used for priority development areas in Montenegro, said Prime Minister Milo Đukanović at the meeting with a delegation of this bank, lead by a member of a Steering Committee Roland Siler.

According to Siler, we are witness to Montenegro’s strong development in the ten years since regaining independence.

“I am pleased with our cooperation so far, in areas of energetics, water management, and possibly road infrastructure”, he said.

Đukanović said that the cooperation is successful, underscoring its value in projects of energetics, infrastructure, traffic and banking.

“I am certain that KfW bank will continue to contribute to economic growth of Montenegro. Its support is especially important in projects of infrastructure, as they are a precondition for developing tourism”, he said.

Đukanović and Siler welcomed the signing of contract on grant for resources from EU – Western Balkan investment framework, between KfW, Ministry of Economy and CGES, as well as the first contract on donation that was granted to Montenegro at Vienna Summit last year.

Here Is Why Google Is Buying a Crazy Amount of Clean Energy

Google just closed on a deal to buy a significant amount of clean energy from two new wind farms that will be built in Norway and Sweden to help power its data centers in Europe.

With this latest deal, Google now has purchased over 2.5 gigawatts of clean energy from around the world to help power its infrastructure that runs its computing services like search, advertising, and cloud computing. That’s the same amount of energy as that produced by two large nuclear plants.

Google GOOG -0.68% has a goal to power all of its operations with clean energy. The search engine giant did its first clean energy deal (called a power purchase agreement) back in 2010 with a wind farm in Iowa.

A big energy customer like Google can help a wind or solar farm get built by committing to buy the power in the planning process. Google has played an important role as an early and large customer willing to purchase major amounts of clean energy.

The two new wind farms announced on Wednesday will be constructed over the coming year near Stavanger, Norway and near Mariestad and Töreboda in Sweden. Together, the two wind farms will use 72 turbines and produce 236 megawatts of clean energy, or about a quarter of the capacity of a large gas or coal plant.

Google isn’t the only Internet giant that’s been focused on using clean energy for its data centers. Apple AAPL -0.94% , Facebook FB -0.17% , Microsoft MSFT 0.02% , Amazon AMZN -0.27% , and others have increasingly been buying wind and solar power to run buildings and data centers.

The world’s largest Internet companies are looking to clean power as a way to lower their carbon emissions, control (or even lower) their energy costs, and adopt more environmental practices. Data centers, which are filled with always-on computers, consume a lot of energy, or about 2% of the electricity in the United States.

Apple has also aggressively been working with solar companies to build large solar farms to power its infrastructure. The iPhone maker has solar farms, or is building solar farms, to power its operations in North Carolina, Nevada, Arizona, and California.

In addition to clean energy, Internet giants are also making sure that their data centers are using energy as efficiently as possible. Part of that is because the more energy used, the bigger the energy bill is for these companies.

The big players like Google and Apple are adopting energy software, using outside air for cooling data centers (instead of power hungry air conditioners), and using servers that can power down when not in use. A report released this week found that the biggest Internet companies are actually doing a pretty good job making their data centers as efficient as possible.

The weird, secret history of the electric car and why it disappeared

Ferdinand Porsche might have founded his famous car company in 1948, but he designed his very first car all the way back in 1898, when he was just 22 years old.

Officially the 1898 Egger-Lohner electric vehicle, C.2 Phaeton, Porsche’s first car is more affectionately known as the P1. Incredibly, it didn’t need a single drop of gas — the P1 was powered by a small electric motor.

The first practical electric car was invented in 1884. In fact, by 1900, more than a third of all vehicles on the road were electric. (Gas-powered cars made up just 22%, and the rest were steam-powered.)

Just like today’s electric cars, the electric cars of a century ago had some major advantages over early gas-powered vehicles.

Early gas cars were clunky, loud, and dirty. Worse, drivers had to physically wrestle with the car to get it to move — every gear shift or hand-cranked start-up involved essentially arm-wrestling an ornery, hateful robot.

Electric cars, on the other hand, were easy to start, easy to drive, and quiet. They weren’t exactly fast or long-range vehicles (they only went about 20 miles an hour), but this wasn’t a problem in cities, where cars were primarily used. Plus the roads outside the city were pretty bad, and no one wanted to drive out there anyway.

Today, Texas is known for its gigantic crude oil production — but back around the turn of the century, we were just really starting to drill, baby, drill. Then, on Jan. 10, 1901, the Lucas No. 1 well in Spindletop blew its top, dramatically ushering in an era of cheap, readily available gasoline for America.

In 1908, Henry Ford dealt a second blow to electric cars when he unveiled the gas-powered Ford Model T.

Largely thanks to Ford’s use of an assembly line, the Model T was much cheaper than any other cars out there, costing only about a third as much as a comparable electric car.
Plus, with the advent of the highway system, people wanted fast, cheap, powerful cars that they could use anywhere.

It’s hard to imagine now, but at the time we also just didn’t have the infrastructure to support electric cars. Today, you can get electricity pretty much anywhere. Before 1910, however, a lot of urban homes weren’t wired for electricity, meaning people couldn’t charge their cars at home. And electric cars certainly weren’t an option for anyone living in a rural area where electricity wasn’t even a thing.

Electric cars were cleaner and easier to operate, and were therefore often marketed specifically toward women — gaining a reputation as being a woman’s car.

Anyway, between weird marketing stigmatization, the low cost of crude oil, the much more affordable Model T, and the introduction of the highway system, by the 1930s, electric cars were pretty much gone.

Today, though, the advantages to electric cars are largely the same — and a lot of the disadvantages are a thing of the past.

Electric cars of today are still cleaner and quieter than gasoline-powered vehicles, and we’re quickly solving a lot of the issues like cost and driving range.

Electric cars have historically been more expensive, but both Tesla and Chevy have announced they’ll be producing electric cars in the actually-kind-of-affordable $30,000 range. Plus we’ve learned that while gasoline has been cheap, our exuberance for burning it and other fossil fuels has been writing the entire planet a massive bill — to the tune of over $1.9 trillion a year by 2100.

That just leaves infrastructure for charging electric cars, which, it turns out, has been growing up right under our noses.

We’re still lacking a lot of the infrastructure we’ll need to make electric cars truly ubiquitous, but it’s slowly starting to appear.

Tesla has been building a gigantic network of Superchargers, and ChargePoint claims to have more than 28,000 chargers ready for public use. Many non-car-related businesses like Walgreens are starting to provide charging stations in order to entice customers as well.
There are even services that let people with charging points at their homes rent them out to other electric car owners. One company, Fisker, even had an idea for a hybrid car that could charge via solar panels on the roof, meaning even needing to find a charging station may one day be a thing of the past.
118 years after Ferdinand Porsche designed the P1, Porsche announced an electric car of its own: the Mission E. Originally just a concept car, Porsche has finally decided to put it into production.

Electric cars aren’t a new fad — they’re intimately tied to the very history of automobiles.

While there are some things they’ll never do quite as well as gas-powered cars — like revving your engine before a big race — it’s awesome to see that we might finally be entering an era where gas and electric cars are sharing the road again.
