Renewable generation capacity increased by 152 GW or 8.3% during 2015, the highest annual growth rate on record, according to new data released by the International Renewable Energy Agency. Renewable Capacity Statistics 2016 finds that as of the end of 2015, 1,985 GW of renewable generation capacity existed globally.
With stronger wind speeds available offshore than on land, wind developers are eager to take advantage of them. However, pile-driven foundations conventionally used to support turbines in shallow waters do not hold up as well in deep waters. Designing a foundation reliable enough to withstand the rugged offshore conditions has been a challenge for the
Wind turbine towers are set to reach heights of up to 170m with new construction techniques and materials, according to wind power engineering specialists K2 Management. Tower heights have grown steadily over the last decade as operators seek stronger wind speeds higher up in the atmosphere.
Siemens was recently awarded an order for the delivery, installation, and commissioning of 12 direct-drive wind turbines for Les Gourlous wind farm in France. The SWT-3.2-113 turbines will have a total capacity of 38.4 MW and will supply about 35,000 households with clean energy. Siemens will be providing long-term service for the new wind farm
ACCIONA Windpower installs more than 1,000-MW of wind-power capacity using concrete-tower technology
ACCIONA Windpower (AWP), the ACCIONA Group subsidiary dedicated to the design, manufacture, and commercialization of wind turbines, has hit a new milestone in the wind industry. The company has installed more than 1,000 MW (1 GW) of wind-power capacity using concrete-tower technology. ACCIONA Windpower’s unique concrete-tower technology enables higher hub heights for better energy production, and
The Lake Erie Energy Development Corporation (LEEDCo) recently began a comprehensive geotechnical investigation of the soils under Lake Erie where they plan to install six Mono Bucket foundations for the Icebreaker offshore wind project. LEEDCo will test the soil and collect samples at each of the six locations, the same type of tests that are

The Sandia Wake Imaging System (SWIS) was deployed for a full-scale field demonstration at the Sandia Scaled Wind Farm Technology (SWiFT) Facility in Lubbock, Texas over the first three weeks of July 2015. The successful field-demonstration was
Major wind-power siting issues haven’t changed a lot over the last few years. Fundamental issues are interwoven with economic, political, environmental, and social complexities. Technological advancements have occurred, but wind power is still more expensive and less reliable than fossil fuel alternatives, according to Jay Maki, a Business Development lead at Land Solutions in Canada.
With the installation of exactly 100 turbines in the period from January 2015 to June 2015, Senvion is now the second largest manufacturer of wind turbines in Germany to date in 2015. The company has installed wind turbines in Germany with a total capacity of over 285 MW in the first six months of this
Editor’s Note: In Dr. Frank Marlowe’s recent article for Broadcast Wind, he discusses the importance of accurately defining potential interference to electromagnetic transmissions caused by the construction of a wind farm. By being proactive and performing a pre-construction impact analysis, a wind farm developer may be able to avoid costly claims for remediation after the fact. His article
