Here’s the world’s most powerful wind turbine

by Ben Schiller, Fast Company In the world of offshore wind energy, bigger is normally better. Larger wind turbines reach higher in the air, where the wind is stronger. Bulkier blades capture more wind. And bigger turbines mean you need fewer, and so are more economical because developers need to drill fewer pilings into the […]

CSU gets ‘overwhelming’ response to request for renewable energy projects

by Jacy Marmaduke, Coloradoan Colorado State University officials are wading through about 75 proposed projects to help the school reach 100 percent renewable energy by 2030.

2018 Solar cost reductions will offset impact of new tariffs on panel prices

by Rocky Mountain Institute Boulder, Colorado, January 23, 2018–Rocky Mountain Institute and 35 solar energy industry leaders committed to develop an ultra-low-cost solar product able to operate in a variety of environments at fully installed costs as low as $0.50/Wp. Participants at the Rocky Mountain Institute-hosted event, representing at least 15 gigawatts of solar capacity—equivalent to […]

Crescent Dunes Solar Energy Facility

24-hour solar energy: molten salt makes it possible, and prices are falling fast

by Robert Dieterich, InsideClimate News The first thing you see of the Crescent Dunes Solar Energy Facility, and you can be miles away, is a light so bright you can’t look directly at it. This sits atop a 640-foot cement tower, rising from the flat, empty Nevada desert around the halfway point on the highway […]

Oil giants see a future in offshore wind power. Their suppliers are investing, too.

by Lyndsey Gilpin, Insideclimate News Transporting an offshore wind array from the factory floor to the ocean floor is no easy feat. Giant, specialized marine vessels must carry the blades and turbines—which sit atop rigs hundreds of feet tall—out miles from shore. Steel or concrete foundations are built to hold them in place, and underwater […]

World’s largest offshore wind farm could send power to five countries

by Lorraine Chow, EcoWatch The Netherlands, famous for its iconic windmills, is planning to build the largest offshore windfarm on Earth by 2027. The vision is so massive that the developers will have to construct a 2.3-square-mile artificial island in the North Sea to support the 10,000-turbine complex. The proposed wind farm, spearheaded by Dutch […]
