This means that the world's cleanest form of energy, hydrogen, may be more easily and cheaply produced. Splitting H2O Physicists at the University of Houston have discovered a low-cost, efficient, and easily available catalyst that can split water into hydrogen and oxygen. The catalyst is far more efficient than other options that have previously been employed, and because it is grown from ferrous metaphosphate on a conductive nickel foam platform, it is both more durable and cheaper to produce. “Cost-wise, it is much lower and performance-wise, much better,” lead author and Anderson professor of physics Zhifeng Ren, M.D. told the University of Houston News.
Breaking water down into its components — oxygen and hydrogen — is theoretically simple, but practically complex. The world spent less money to add more renewable energy than ever in 2016. A new study tracking global investment in renewable energy found that investors spent less money in 2016 to add more renewable energy capacity than in any previous year.
In total, investors only spent about $241.6 billion in renewable energy investments in 2016, down 23 percent from 2015. But they got a lot of bang for their buck. According to the collaborative report from the UN, the Frankfurt School, and Bloomberg New Energy Finance, investments in “wind, solar, biomass, and waste-to-energy, geothermal, small hydro, and marine sources [like wave and tidal energy]” resulted in the addition of 138.5 GW of energy capacity in 2016. Marine power: can UK companies rule the waves? “In two weeks we face the full brunt of the South Westerlies and we’ll see what the sea is going to do to us.”
Simon Gillett has a habit of talking about the device his company, Wave-tricity, has created as an extension of himself. This must be a nerve-wracking time. The Ocean Wave Rower, launched into West Wales’s Milford Haven estuary in March, is undergoing a period of initial testing before it gets towed out to the open seas. It’s an attempt to crack one of the toughest engineering problems in renewable energy: how to extract usable energy from the ocean waves, and do it affordably.
Embedded fuel cells power smartphones for a week… and could run the world. People love their smartphones but hate poor battery life.
We love having access to the world’s information at our fingertips but tire of the need to constantly plug in to the world’s electricity grid. The recharging model of batteries fails us — the marketplace is ready for a new approach to portable power. We may be entering the early days of refueling products to gain longer performance and freedom from cords and electric sockets.
Beyond powering our devices 10 times longer than batteries, this refueling model of personal power systems might also set the stage for a “leapfrog” energy scenario that brings billions of people into the age of electricity by delivering clean fuels to retail shelves. Refueling versus recharging In January of this year, social media spread viral stories about a CES demonstration of an iPhone that could hold its power for a week, and shared images of a hydrogen-fueled drone that could fly six times longer than a battery-operated version. Scientists Accidentally Discover Efficient Process to Turn CO2 Into Ethanol. Scientists at the Oak Ridge National Laboratory in Tennessee have discovered a chemical reaction to turn CO2 into ethanol, potentially creating a new technology to help avert climate change.
Their findings were published in the journal ChemistrySelect. [Go here for a new in-depth interview about the findings with one of the lead researchers.] The researchers were attempting to find a series of chemical reactions that could turn CO2 into a useful fuel, when they realized the first step in their process managed to do it all by itself. The reaction turns CO2 into ethanol, which could in turn be used to power generators and vehicles. Poo power: Dutch dairy industry launches €150m biogas project. The air smells fruity, slightly alcoholic.
Against the strong hum of machinery, 175 cows are eating hay. As their dung drops to the slatted floor, a machine sweeps it through and it runs underneath the barn to a futuristic dome outside. The Heegs’ 75-hectare family farm in remote Friesland, in the north-west of the Netherlands, where cows outnumber people almost two to one, marks the start of a national experiment to encourage farms to turn their manure into biogas. The process is simple: the dung is broken down by bacteria into biogas in an anaerobic digester. Other machines then extract nitrates and phosphates to make fertiliser, leaving organic matter, which is spread on the Heegs’ farm. Masterminded by FrieslandCampina, the country’s largest dairy collective which buys milk from 13,500 of the Netherlands’ 17,000 dairy farmers, the project has established an initial target of getting 1,000 large farms across the country to make power from cow manure within four years. A Fossil Free Tomorrow: LA Takes Steps Towards 100% Clean Energy.
In Brief The LA City Council has adopted a measure that instructs its power utility managers to collaborate with local stakeholders to find the best way towards a 100% clean energy portfolio.
Running on 100% clean energy is all the rage right now, with major cities pledging to completely phase out fossil fuels in their energy mix. This movement has gotten so big that a whole country, Costa Rica, ran completely on renewables for almost 300 days. Now, the city of Los Angeles is taking a step towards that fossil fuel-free future. Inhabitat - Green Design, Innovation, Architecture, Green Building. As many nations are discussing the best methods to reduce reliance on fossil fuels and slow down global warming, a few countries are lightyears ahead of the game.
Costa Rica has achieved 99 percent renewable energy use this year, showing the rest of us it’s possible to use sustainable and readily available energy sources if we want it badly enough. Costa Rica’s lush jungles and waterfalls make hydropower one of the most accessible natural energy resources in the country, yet geothermal plants are catching up quickly, and officials hope to continue to build this and other industries.
The Battery Miracle Will Transform Both Transportation And Power Generation. Low-cost, high-performance electric batteries are a game changer for the two key clean energy sectors: power generation and transportation.
They enable much greater adoption and penetration of both renewable energy and electric vehicles — not just electric cars but electric buses and electric planes. Since lithium-ion batteries have only just crossed the key price point for enabling widespread usage in both sectors — $300 per kilowatt-hour — we are really just at the beginning of the battery-driven clean energy revolution. Bloomberg New Energy Finance (BNEF) projects that over the next 25 years, small-scale battery storage will become a $250 billion market.
They “expect total behind-the-meter energy storage to rise dramatically from around 400 MWh in today to nearly 760 GWh in 2040″ — nearly a 2,000-fold increase! BNEF makes the case we’ve crossed a similar tipping point for electric car batteries in this new chart: Also, it’s not just cars that are going electric. A Quarter Of The World's Power Now Comes From Renewables. In Brief Renewable energy now accounts for a quarter of the world's power, according to a new global report by REN21.
The Rise of Renewables The days of fossil fuels may finally be numbered. A new report states that renewable energy now accounts for a quarter of the world’s power. REN21 published a global status report for renewables, highlighting that renewable energy was already supplying about 23.7% of global electricity by the end of 2015. Renewable energy surges to record levels around the world. Image copyright Getty Images New solar, wind and hydropower sources were added in 2015 at the fastest rate the world has yet seen, a study says.
Investments in renewables during the year were more than double the amount spent on new coal and gas-fired power plants, the Renewables Global Status Report found. For the first time, emerging economies spent more than the rich on renewable power and fuels. Berkeley Lab research on how lithium-rich cathodes work is leading to 50% higher capacity lithium ion batteries. In the quest for a radically better lithium-ion battery, a promising direction is the so-called “lithium-rich” cathode, in which the cathode contains a higher proportion of lithium than normal. While it has the potential to have far higher energy density, scientists have lacked a clear picture of the chemical processes, especially the role of oxygen. Now researchers at the Department of Energy’s (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab) report a major advance in understanding how oxygen oxidation creates extra capacity in such cathodes, opening the door to batteries with far higher energy density, meaning your phone or electric vehicle will be able to run for much longer between charges.
Why cheap green energy could derail the renewable revolution. Rolf Schulten/Bloomberg via Getty Images By Michael Le Page “Germany had so much renewable energy on Sunday that it had to pay people to use electricity.” That was the striking headline on the Quartz news site last week. Excess electricity can overload a grid, so to even things out some big consumers were paid to up their energy use. Why clean energy is now expanding even when fossil fuels are cheap.

Makawanpur village illuminated with wind-solar energy - The Himalayan Times. A wind-solar energy project being run in Phaparbari village of Makawanpur district.
Photo: RSS MAKAWANPUR: Chatur Bahadur Ghalani of Bhorleni, Phaparbari VDC-3 in Makawanpur district had never believed that electricity could be generated from other sources besides water and sun. When his house and the entire village were illuminated by the electricity generated from wind which often blows severely from dawn to dusk across the village, Ghalani now does not believe his eyes. The Wind-Solar Hybrid Energy Project, installed by the Alternative Energy Promotion Centre (AEPC) in Bhorleni in the district, produces 25 kilowatt of energy -10 kilowatt from wind and 15 kilowatts solar, adequate enough to illuminate the village.
As many as 131 households in Bhorleni are not only happy but also consider themselves lucky to access electricity round the clock at time when the country is reeling under the power outage up to 14 hours a day. Recommended Stories: Scientists combine coal waste and algae to create a new super-clean fuel. Scientists have discovered a new, clean-burning fuel made from unlikely ingredients: coal dust and algae. Coalgae is easy to produce, low in cost, burns without smoke, and researchers believe it can be make a major dent in crude oil imports. It also provides a market for reusing the 50-million to 60-million tonnes of coal dust produced annually as a byproduct of the coal mining industry. Uruguay makes dramatic shift to nearly 95% electricity from clean energy. As the world gathers in Paris for the daunting task of switching from fossil fuels to renewable energy, one small country on the other side of the Atlantic is making that transition look childishly simple and affordable.
In less than 10 years, Uruguay has slashed its carbon footprint without government subsidies or higher consumer costs, according to the country’s head of climate change policy, Ramón Méndez. In fact, he says that now that renewables provide 94.5% of the country’s electricity, prices are lower than in the past relative to inflation. Global Development Professionals Network. 1.

Scientists seek to harvest electricity from algae in green-energy effort. Storing solar, wind, and water energy underground could replace burning fuel. Using wind, water, and solar electricity for everything, instead of burning fuel, with resulting improved energy efficiency, means you need much less energy (credit: The Solutions Project/data: Stanford University) Stanford and UC Berkeley researchers have a solution to the problem of storing energy from wind, water and solar power overnight (or in inclement weather): store it underground.
The system could result in a reliable, affordable national grid, replacing fossil fuel, they believe. This could be the biggest sign yet that the battery revolution is here. The California Inland Empire Utility Agency’s solar panels, located at three of the Agency’s recycled water facilities and IERCF, generate 3.5 MW of clean solar power and will reduce electrical costs at its facilities — the single largest component of IEUA’s operating budget. The solar project is funded in part under the State’s Innovative California Solar Initiative. The world's first solar-powered bike path is generating more energy than expected. It’s been one year since an innovative solar-paneled bike path was laid in Krommenie, Netherlands, and the results have even surprised the designers.
