Spanish-German wind giant Siemens Gamesa has been awarded a firm order for 60 of its SG 14-222 DD offshore wind turbines, which will be installed at the 882-MW Moray West offshore wind farm in Scotland. It will be the first installation of the world’s most powerful wind turbine, which has 14.7 megawatts (MW) of capacity.…

Italian startup Energy Dome has now begun to commercialize the world’s first CO2 Battery, which was launched earlier this month in Sardinia, Italy. The battery uses carbon dioxide to store renewable energy on the grid, and Energy Dome says the technology can be quickly deployed anywhere in the world. June 28 update: Energy Dome…

Stockholm-based wind farm and solar developer OX2 has applied for a permit to build a massive 5.5 gigawatt (GW) offshore wind farm in the Baltic Sea. If approved, it will be the largest single offshore wind farm in the world. World’s largest single offshore wind farm Ørsted’s Hornsea in the North Sea has 7.5…

The US Supreme Court, in a 6-3 ruling this morning, “sharply curtailed” the Environmental Protection Agency’s (EPA’s) options to regulate greenhouse gas emissions from existing power plants – the second-largest source of emissions in the US. Greenhouse gas emissions cause climate change. What the ruling said In 2007, the Supreme Court recognized EPA’s authority…

Rhode Island has passed a law requiring all of the state’s electricity to be offset by renewable energy by 2033 – the fastest timeline of any state in the US.

Danish wind turbine maker Vestas has installed the first wind turbine at Japan’s Akita Noshiro offshore wind farm. Akita Noshiro will feature 33 V117-4.2 megawatt (MW) wind turbines. Japan already operates several demonstration offshore wind turbines, but Akita Noshiro is its first commercial offshore wind farm. Akita Noshiro offshore wind turbine. Photo: Vestas Twenty wind…

For the first time ever, wind and solar produced 17.96% more electricity in the month of April than nuclear power plants.  Further, electrical generation by clean energy – which included biomass, geothermal, and hydropower and was driven by strong solar and wind growth – accounted for almost 30% of total US electrical generation in…

Finnish startup Polar Night Energy and local Finnish utility Vatajankoski have together built the world’s first commercial sand-based, high-temperature heat storage system that can be powered by solar and wind. Sand-filled energy storage in Finland Polar Night Energy’s heat storage system is a 23-foot-tall steel container filled with 100 tons of sand. (Polar Night…

Eleven US East Coast states have already committed to procuring nearly 40 gigawatts (GW) of offshore wind power. But increasingly powerful Atlantic hurricanes will be a threat to those future offshore wind farms. A team of scientists investigated how to make offshore wind turbines more resilient – they found that when they turned an offshore…
