Ian Johnson for Independent: A record-breaking solar panel that can convert more than a quarter of the sunlight it receives into electricity has been developed by researchers in Japan.
Tracking is still relatively young -- the majority of deployments have really been in just the past few years -- but it's growing up fast.
Space-based solar power (SBSP) --- in which satellites in Earth orbit capture the Sun's radiation, convert it to electricity and then transmit it back to Earth in the form of either microwaves or lasers --- would arguably do more to positively impact the lives of everyday Americans and fellow citizens of the world than almost anything the new President could champion.

Solar projects can be a great investment for many businesses and offer a solid ROI, but it takes time and energy to put together a project that works for all the interested parties-the customer, the bank, and the installer.
Steve Dent¬ for engadget: ¬ A five kilowatt rooftop solar installation¬ now costs¬ just $12,500 on average after tax credits, and pretty soon, installing one might soon be a matter of¬ re-tiling your roof. Whether it's right for you, however, depends in large part on how much sun your house gets. That's where Google's Project Sunroof comes in -- launched just two years ago, it has now surveyed over 60 million US buildings in 50 states. That means there's a good chance you can see the electricity production potential in your city, neighborhood and even specific house. Google calculates the amount of sunlight on your roof based on "3D modeling of your roof and nearby trees," weather patterns, the position of the sun in the sky during the year and shade from buildings, trees and other obstructions. That info is then converted to energy production "using industry standard models for solar installation performance," Google says. ¬ Cont'd...
University of Cambridge via Biomass Magazine: ¬ Dr Moritz Kuehnel, from the Department of Chemistry at the University of Cambridge, joint lead author on a new research paper published in Nature Energy, says: "Lignocellulose is nature's equivalent to armoured concrete. It consists of strong, highly crystalline cellulose fibres, that are interwoven with lignin and hemicellulose which act as a glue. This rigid structure has evolved to give plants and trees mechanical stability and protect them from degradation, and makes chemical utilisation of lignocellulose so challenging." The new technology relies on a simple photocatalytic conversion process. Catalytic nanoparticles are added to alkaline water in which the biomass is suspended. This is then placed in front of a light in the lab which mimics solar light. The solution is ideal for absorbing this light and converting the biomass into gaseous hydrogen which can then be collected from the headspace. The hydrogen is free of fuel-cell inhibitors, such as carbon monoxide, which allows it to be used for power. ¬ Full Article:
Diane Cardwell for The New York Times: ¬ Brooklyn is known the world over for things small-batch and local, like designer clogs, craft bourbon and artisanal sauerkraut. ¬ Now, it is trying to add electricity to the list. In a promising experiment in an affluent swath of the borough, dozens of solar-panel arrays spread across rowhouse rooftops are wired into a growing network. Called the Brooklyn Microgrid, the project is signing up residents and businesses to a virtual trading platform that will allow solar-energy producers to sell excess-electricity credits from their systems to buyers in the group, who may live as close as next door. The project is still in its early stages - it has just 50 participants thus far - but its implications could be far reaching. ¬ Cont'd...
Due to extreme weather, high solar radiation, high UV index and the salinity of certain areas, the Atacama Desert in Chile presents conditions that contribute to the early degradation of instrumentation, communication and energy systems.
Depending on the size of your solar system and the amount of solar you produce each month, you can greatly reduce your monthly electric bills, and even profit from it.
Sami Grover for TreeHugger: Offshore wind energy has been growing like crazy in the last few decades—so much so that there's even talk of serious talk of multi-gigawatt offshore wind farms in the US in the not too distant future. But offshore wind has so far been limited to areas where the seafloor is relatively shallow, and where it's easy to build foundations for these gigantic turbines. Floating wind turbines are different. Instead of using fixed foundations, they are anchored to the sea floor using cables. And that means they can be located in deeper waters, opening up many more areas where wind conditions are favorable and concerns about views and/or bird migration routes are less relevant. Alongside opening up new areas for development, the other major advantage of floating turbines—once they are being developed at scale—could also be reduced costs. Cont'd...
Phys.org: A major roadblock to the mass use of solar energy are photovoltaic (PV) solar cells. This is because the cost, inefficiency and negative environmental impact that the manufacturing of these cells outweighs any potential savings provided by the resulting solar energy. If, however, cost could be were minimised, then solar power would be more able to compete with traditional fossil fuel-based methods for generating energy. To overcome this hurdle, the EU-funded SOLNOWAT project has developed an innovative dry process for manufacturing PV solar cells. PV cells are typically created via a wet chemical process that etches away layers of silicon from a crystalline wafer, leaving behind the solar cell. The SOLNOWAT process replaces the expensive and inefficient wet chemical process with the use of atmospheric pressure dry etching technology – a process that cuts costs and speeds up production. Because less silicon is removed during dry etching, the resulting cells are darker, making them very efficient at absorbing light. In fact, they are so efficient that they have been classified as having zero global warming potential. Cont'd...
Ikea, one of the leading retailers of finished goods in the world, has installed a 1.125 MW solar array on their new facility in Renton Washington. It is the latest Ikea in the US to be powered by the sun and the largest roof top install in Washington State.
Iowa, South Dakota, Kansas, Oklahoma and North Dakota all sourced more than 20 percent of their electricity generation from wind power during 2016, according to new data from the U.S. Energy Information Administration (EIA). It shows wind supplied over 5.5 percent of electricity nationwide, up from 4.7 percent in 2015. With 99 percent of wind turbines located in rural areas, wind power's steady growth as a share of the nation's electricity supply has been accompanied by a surge of investment in rural America. The industry invested over $13.8 billion in new turbines last year, according to the American Wind Energy Association (AWEA), in addition to operating a fleet now over 52,000 turbines. Full AWEA Press Release:
The installed 840 floating PV panels have a total peak capacity of 220 kilowatts and is expected to generate 332 megawatts per hour in its first year - equivalent to the annual consumption of around 100 homes.
