Schmitz, an Iowa State graduate student of civil, construction and environmental engineering, and Sri Sritharan, Iowa State’s Wilson Engineering Professor and leader of the ‘s College of Engineering’s Wind Energy Initiative, were trying to answer some basic questions about using concrete panels and columns to build wind turbine towers using prefabricated, easily transportable components.
Wind energy capacity is growing rapidly in the cold climates of the world. According to the latest forecasts, between 45 and 50 gigawatts of wind energy will be built in cold climates by 2017, which would mean an increase of as much as 72 per cent since the end of 2012 and investments amounting to approximately EUR 75 billion.
The National Nuclear Security Administration (NNSA) has awarded a contract to Siemens Government Technologies, Inc. (Siemens) to construct the federal government’s largest wind farm. The Pantex wind farm is expected to save an average of $2.9 million annually over the 20-year contract term. The installation will consist of five 2.3 megawatt turbines located on 1,500 acres of government-owned property east of the Pantex plant in Amarillo.
Awareness is growing in the wind industry about the severe impact that erosion on the leading edge of wind blades can have on turbine output. Erosion can lead to a significant loss in annual energy production, costing owners and operators thousands of dollars. Blade repair and protection can help provide significant annual energy production improvements, reduce costly downtime, and protect the integrity of the blade.
Researchers from the U.S. Department of Energy’s (DOE) SLAC National Accelerator Laboratory and Stanford University have designed a low-cost, long-life battery that could enable solar and wind energy to become major suppliers to the electrical grid.
D.C.’s Union Station Now Powered by 100 Percent Wind Energy Provided by Washington Gas Energy Services
Union Station will transition to 100 percent wind power for its electricity load of 18,943,964 kilowatt hours annually. This is equivalent to avoiding the consumption of more than 1,400,000 gallons of gasoline or taking more than 2,700 cars off the road for one year. The world’s fastest-growing energy resource, wind power displaces conventional power, reduces carbon dioxide and helps eliminate air pollution.
The Small Wind Turbine (SWT) industry is maturing, signaled by the expanded role of SWT certification, the existence of hundreds of manufacturers located around the world, the expansion of dealer networks, and the growing number of national and regional industry associations. The number of applications is also growing, including applications in telecommunications, defense, and other sectors that involve producing power in remote locations. According to a new report from Navigant Research, annual global installations of SWTs will roughly double in the next five years, growing from 86 megawatts in 2012 to 172 MW in 2018 and representing $3.3 billion in revenues.
Between midnight Monday and midnight Tuesday, the 1.1 million homes and businesses powered by PSE received 23.5 percent of their electricity from the utility’s three Eastern Washington wind farms.

The Makamaka`ole seabird mitigation project is part of an extensive program undertaken by the company to provide conservation benefits to mitigate potential impacts of the Kaheawa Wind projects several miles away. As part of the company’s innovative Habitat Conservation Plan for its two Kaheawa Wind projects on Maui, First Wind is constructing two fenced enclosures to protect the federally endangered Hawaiian Petrel and threatened Newell’s Shearwater, two native Hawaiian seabirds. The enclosures are located about ten miles west of Wailuku.
The New Jersey Energy Link will be an offshore electrical transmission cable, buried under the ocean, linking energy resources and users in northern, central and southern New Jersey. The cable will span the length of New Jersey and when complete could carry 3,000MW of electricity. The New Jersey Energy Link is expected to be built in three phases over a decade. The New Jersey Energy Link is expected to begin construction in 2016 and the first phase to be in service in 2019.
“The completion of the Pinyon Pines Wind I and Pinyon Pines Wind II projects bring MidAmerican Wind’s renewable energy portfolio to 381 megawatts,” said Tom Budler, president of MidAmerican Wind. “We are pleased to have met our timeline for building the two projects and placing them in-service before year-end 2012.”
