Eleven new wind turbines have been added at the La Ventosa wind power complex in Juchitán de Zaragoza, Oaxaca, Mexico, raising the total capacity to 102 MW. Iberdrola, owner of the wind farm, has utilized Gamesa technology exclusively at all of its installations in Mexico. In this instance, 2-MW G80 wind turbines, standing 78-meters (256-feet) […]

The controversial federal production tax credit (PTC) bestowed on new wind farms of $0.023/kWh for the first 10 years of their operation expired on Tuesday, but the impact of that policy lapse isn’t immediately clear. Originally enacted in 1992, the federal renewable electricity PTC has been renewed and expanded numerous times—most recently by the American […]

A land of lakes and rivers, Quebec benefits today from an abundance of clean and green energy, vastly generated by means of hydro power, which is increasingly complemented by the province’s eastern wind energy farms. Download a pdf of this report.

MidAmerican Energy Co. is already the top ranked, rate-regulated utility owner of wind generation in the U.S. and with 448 new wind turbines being added in Iowa—the largest wind expansion in the state’s history—its hold on that position will be further strengthened. In November, the company announced it had reached an agreement with Highland Wind […]

New research conducted by Massachusetts Institute of Technology and Santa Fe Institute researchers finds that the number of energy patents is increasing faster than patents overall. However, the trend lines

Recently, the variable generation (VG) industry has been strongly promoted in China to advance sustainable energy development, especially for wind power and solar photovoltaic (PV) power, which have entered

America is blessed with long coastlines and relatively deep waters. But ironically, this has been a disadvantage to the U.S. offshore wind industry. Compared to more than 1,000 turbines that are already

Germany’s levy to promote renewables under the 2008 Renewable Energy Act (EEG) will climb to €0.624/kWh in 2014—a 20% increase that represents nearly a fifth of residential electricity bills. The measure

Up to 18% of the world’s electricity could be generated with wind energy by 2050, but the massive jump from 2.6% today would require the nearly 300 GW of current wind capacity worldwide to increase eight- to

Legislative efforts to establish a federal renewable electricity standard (RES) kicked up last week with the separate introduction of two bills by Senate Democrats. Sens. Tom Udall (D-N.M.), Mark Udall (D-Colo.), and Ben Cardin (D-Md.) on Oct. 29 introduced the Renewable Electricity Standard Act of 2013 (S.1595), a bill that would create a national standard of 25% renewable energy […]

A new study from Stanford University suggests that, if the overall amounts of fuel and electricity required to build and operate energy storage technologies are factored in, grid-scale batteries make sense for

A tremendous amount of offshore wind capacity—from 100 MW to 13,000 MW—is expected to play a major role in Germany’s transition to sourcing 80% of its power from renewables by 2050. However, Energiewende

Norwegian energy company Statoil last week canceled its $120 million project to put four 3-MW wind turbines on floating spar-buoy structures 12 miles offshore of Maine’s Boothbay Harbor. The Maine Public Utilities Commission (MPUC) had in January 2013 approved terms of Statoil’s proposed Hywind Maine project, and the Bureau of Ocean Energy Management last year […]

Greenhouse gas (GHG) emissions from power plants plunged 10% in 2012 largely due to the coal-to-gas switch and a slight decrease in power production, the Environmental Protection Agency (EPA) said on Wednesday. Earlier this week, the Energy Information Administration (EIA) reported similar findings. The EPA’s 2012 data from its GHG Reporting Program, which collects annual […]

A federation of Germany’s biggest companies last week called for urgent reforms to the country’s renewable energy strategy within the first 100 days of Chancellor Angela Merkel’s newly elected government, including abolishing feed-in-tariffs (FITs) that they say have sent power prices in the country soaring. Key points of the 19-page reform proposal submitted by the […]

California’s drive to add flexibility to its grid in response to expanding renewable generation took another step forward in September as NRG Energy commissioned two new fast-start units at its El Segundo Energy Center near Los Angeles. The two units, with a combined 550 MW capacity, represent the second Siemens Flex-Plant to go into commercial […]

A prototype 100-kW floating wind turbine that has been tested off Nagasaki near Japan’s Kabashima Island since May 2012 is slated to be replaced by a full-scale, grid-connected 2-MW wind turbine this fall

POWER Associate Editor Sonal Patel reported on Sept. 12 that “nearly 100 renewable energy and environmental groups and businesses have asked the Energy Information Administration (EIA) to reevaluate renewable energy forecasts, alleging the agency’s projections don’t reflect ‘the current status and recent, real-world growth rates of renewables.’” The EIA forecasts are presented in its Annual […]

Much attention has been devoted recently to the increased cycling that is necessary in fossil plants as more renewable capacity is added to the grid, but data on the precise impacts has been slight. Now, a new study from the National Renewable Energy Laboratory (NREL) aims to correct that. The key findings: While cycling would increase […]

Nearly 100 renewable energy and environmental groups and businesses have asked the Energy Information Administration (EIA) to reevaluate renewable energy forecasts, alleging the agency’s projections don’t reflect “the current status and recent, real-world growth rates of renewables.” In a Sept. 10 letter to EIA Administrator Adam Sieminski, the coalition says the agency’s estimates in past […]

Dominion Virginia Power is the provisional winner of the Interior Department’s second competitive lease sale of federal land off the coast of Virginia to develop an offshore wind farm. The company bid $1.6 million to win the lease for 112,800 acres. In a statement on Wednesday, the Dominion subsidiary said it will use the land […]

The $2.9 billion London Array—the world’s biggest offshore wind farm—opened this July in the Outer Thames Estuary about 12 miles off the coasts of Kent and Essex. The 175-turbine installation is arranged

When Gary Leonard, General Electric’s global technology director for aero-thermal and mechanical systems technologies, spoke with POWER Contributing Editor Mark Axford at this year’s Gulf Coast Power

A new report from the National Renewable Energy Laboratory (NREL) suggests wind and solar generation could become cost-effective without federal subsidies if they are sited in the most productive locations. “It is too early to say how strong the post-2025 market for renewables will be or whether it will be primarily market-driven or policy-driven. In […]

Europe’s third-largest power provider on Tuesday announced it would take offline 3.1 GW of natural gas and coal power plants in Germany and the Netherlands, citing a “continuing boom in solar energy.” Echoing several European utilities, Germany-based RWE has underscored the declining profitability of fossil fuel–fired plants that it says is pegged to fundamental changes […]

Wind power installations in 2012 represented a 43% majority of all new power capacity additions in the U.S. and accounted for $25 billion in U.S. investment, two new reports from the Department of Energy show. The Lawrence Berkeley National Laboratory (LBNL) released the “2012 Wind Technologies Market Report,” which details the latest trends in the […]

The Bureau of Ocean Energy Management (BOEM) will hold its second competitive lease sale for renewable energy on the U.S. Outer Continental Shelf (OCS) offshore Virginia this September.

An updated energy flow chart released by the Lawrence Livermore National Laboratory (LLNL) that visually depicts the relative size of primary energy resources and end uses in the U.S., with fuels compared on a common energy unit basis, shows the nation consumed more natural gas and renewables but less coal in 2012.

The U.S. Energy Information Administration’s (EIA’s) International Energy Outlook 2013 (IEO2013) released today projects that renewable energy and nuclear power will each increase 2.5% per year through 2040, but fossil fuels will continue to supply almost 80% of world energy use by 2040.
