Now offshore wind is not only far cheaper than new nuclear but competitive with gas

EnergyDesk, 11 Sep 2017 © Greenpeace / Bas Beentjes Energy from offshore wind just got a lot cheaper. The cost of subsidies for new offshore wind farms has halved to £57.50 per megawatt hour (MWh) since the last government auction in 2015, after two developers – Denmark’s Dong Energy and Spain’s EDP – bid aggressively for subsidy contracts to build …

South Australia’s “baseload” wind supply

By Giles Parkinson, Reneweconomy, on 5 September 2017 I’m sure that people in South Australia can confirm that it has been windy over the last few days. What might surprise them is how wind has dominated the state’s electricity supply – and how consistent its output has been. This graph below comes from Dylan McConnell at Melbourne’s Climate and Energy College and …

NREL confirms wind and solar are cheapest generation

Clean Technica, 25 Aug 2017 The United States Energy Department’s National Renewable Energy Laboratory has updated its analysis of electricity generation technology costs, and it’s good news again for wind and solar, which come out cheapest alongside natural gas. The National Renewable Energy Laboratory (NREL) has released its 2017 Annual Technology Baseline (ATB), the third edition of its highly respected analysis of …

Denmark Just Generated 140% of Its Electricity Demand From Wind Power, sold the excess to Germany, Norway and Sweden

Eugene Suslo/Shutterstock.com Science Alert, 15 July 2017 On a particularly windy day last week, Denmark’s wind farms produced between 116 and 140 percent of the national electricity requirements, and they weren’t even operating at their full 4.8GW capacity at the time. Eighty percent of the excess was shared by Germany and Norway, and Sweden got 20 percent of the spoils, …

Super-Colossal Wind Turbines May Be on the Horizon

Super-Colossal Wind Turbines May Be on the Horizon – Aug.03.2017 In 2000, there were just a handful of utility-scale turbines. Today, more than 52,000 generate about 6 percent of the nation’s electricity. The growth of wind power is accelerating (see graph below); it accounts for more than two-thirds of all the renewable energy capacity installed in America since 2008. And …

NREL reports on ways to cut the cost of wind energy in half

From the beginning of a press release announcing a new NREL report. It’s headlined “New Lab Report: How to Cut the Cost of Wind Energy in Half,” and the news for natural gas is all downhill from there. Produced by the Energy Department’s National Renewable Energy Laboratory, the report notes that wind is already inching into a competitive position in some …

Increasing droughts, lower crop yields (just 40% already in Utah and forecast to go to 10%), and increased stress and conflict

A new study by MIT climate scientists, economists, and agriculture experts finds that certain hotspots in the country will experience severe reductions in crop yields by 2050, due to climate change’s impact on irrigation. The most adversely affected region, according to the researchers, will be the Southwest. Already a water-stressed part of the country, this region is projected to experience …

It’s always windy somewhere: Europe seeks to balance renewables. Harnessing wind in the Balkans and Scandinavia would get there

Ars Technica, By John Timmer, 18 July 2017 Renewable power sources’ intermittency could eventually cause problems as our electric grids become increasingly reliant on them. While it’s always sunny somewhere, and always windy somewhere (often somewhere else), relying on weather variations for generating consistent power means integrating power sources across a large geographic region. Many countries, including several leaders in …

World’s largest wind turbine will be as tall as a skyscraper and bend with storm winds like the palm trees that inspired them

By Annie Sneed in Scientific American, on June 26, 2017 Credit: Wolfgang Kaehler Getty Images Wind energy is soaring in the U.S.; the nation’s renewable energy capacity has more than tripled in the past nine years, and wind and solar power are largely responsible. Now businesses want to harness even more wind energy, at a cheaper price—and one of the best ways …
