Mark Gilbert for Bloomberg: The U.K. government is mulling whether to support a 1.3 billion pound ($1.6 billion) proposal to build a tidal lagoon in South Wales. It should stop dithering and subsidize the project to help meet the country's green energy goals, produce cheaper power, and establish Britain as the world leader in technology that harnesses the power of the tides to generate electricity.
The U.K. lost its energy independence in 2004, and now depends upon imports to meet about half of its energy needs. And while the contribution from renewable energy sources has climbed to a bit less than 10 percent from about 1 percent at the start of the last decade, the U.K. commitment to reduce carbon emissions to 57 percent of their 1990 levels by 2030 means even less electricity needs to come from coal-fired power plants.

Sue Holmes for Phys.org: People think of corrosion as rust on cars or oxidation that blackens silver, but it also harms critical electronics and connections in solar panels, lowering the amount of electricity produced.
"It's challenging to predict and even more challenging to design ways to reduce it because it's highly dependent on material and environmental conditions," said Eric Schindelholz, a Sandia National Laboratories materials reliability researcher who studies corrosion and how it affects photovoltaic (PV) system performance.
Sandia researchers from different departments collaborate to accelerate corrosion under controlled conditions and use what they learn to help industry develop longer-lasting PV panels and increase reliability. For example, work by Olga Lavrova of Sandia's Photovoltaic and Distributed Systems Integration department demonstrated, for the first time, a link between corrosion and the risk of arc faults in PV systems' electrical connections. Research by Erik Spoerke of Sandia's Electronic, Optical and Nano Materials department focuses on developing new nanocomposite films that could dramatically increase reliability. Cont'd...

John Anderson for NewAtlas: A behemoth V164 offshore wind turbine from Danish company MHI Vestas Offshore Wind has produced almost 216,000 kWh over a 24-hour period during tests at its site near Østerild, Denmark in December. In doing so, the 9 MW prototype – a reworked version of the V164-8.0 MW, which was initially developed in 2012 and launched two years later – takes the energy generation record for a commercially available offshore wind turbine.
Since its launch in 2014, the Usain Bolt of wind turbines is essentially in competition with itself, largely due to its superior size over the competition. The V164 stands at 722 feet (220 m) at full height, with 38-ton blades that are 263 feet (80 m) in length for a total sweep area of 227,377 square feet (21,124 square meters) – larger than the giant London Eye Ferris wheel.
