Iowa Utility to Build a 310-Megawatt Wind Power Plant

MidAmerican Energy Company, Iowa’s largest utility, announced last week its intention to construct a 310-megawatt wind power facility in northwest or north-central Iowa. The project will consist of up to 200 wind turbines and will rival in capacity the largest existing U.S. wind power plant: the 300-megawatt Stateline Wind Energy Center, located along the border of Oregon and Washington. Although MidAmerican expects the first turbines to come online in 2004, and the entire project to be complete by 2006, the company has not yet selected a location for the project.

Rosebud Sioux Tribe Installs a 750-Kilowatt Wind Turbine

The Rosebud Sioux Indian Tribe installed a 750-kilowatt wind turbine on its reservation last week, completing a project that began eight years ago with wind resource monitoring. With half of the project funded by a DOE Cooperative Grant, the Rosebud Tribe financed the remainder of the project by obtaining the first-ever loan for a tribal wind energy project from the U.S. Department of Agriculture’s Rural Utility Service. The project will supply power to the reservation and will also sell power to the Basin Electric Power Cooperative. “Green tags” from the project are also being sold through NativeEnergy, LLC.

The Rosebud Sioux Tribe is located in south-central South Dakota. DOE estimates that the 24 reservations in the northern Great Plains have a wind energy potential greater than 300 gigawatts. [sorry this link is no longer available]

Clif Bar Inc., a maker of all-natural energy and nutrition foods, is the latest buyer of green tags from NativeEnergy. Clif Bar is buying enough green tags to displace about 2,000 tons of carbon dioxide emissions. [sorry this link is no longer available]


Solar Power Installations Continue Apace in California

California continues to maintain a rapid pace for solar power installations, judging by recent announcements from Shell Solar and PowerLight Corporation. In March, the two companies announced a total of nearly 800 kilowatts of new solar energy installations.

PowerLight Corporation dedicated two solar electric systems in Vallejo: a 108-kilowatt system on Vallejo City Hall and a 224-kilowatt system on the John F. Kennedy Public Library. The company also dedicated a 231-kilowatt system installed on the roof of OK Produce’s distribution facility in Fresno. [sorry this link is no longer available]
The Shell Solar announcements include a 150-kilowatt system at Salina Valley Memorial Hospital in Monterey County, a 73-kilowatt system in Los Angeles, and a 1.76-kilowatt system that will help monitor the California Condor at the Hopper Mountain National Wildlife Refuge in Southern California.

European Wave and Tidal Energy Projects Face Setbacks

Two European projects to demonstrate wave and tidal energy production — one in Denmark and one in Norway — have recently encountered setbacks and delays.

In Denmark, a wave energy system called the Wave Dragon was damaged during its deployment over the weekend, when high winds caused the installation team to stop work, apparently before the mooring system was fully installed. The ensuing storm caused damage to the prototype, but it remains afloat. [sorry this link is no longer available]

The Wave Dragon is an offshore floating device that captures ocean waves in an elevated reservoir, then converts that reservoir’s stored energy into electricity by running the water through a hydroelectric turbine as it is returned to the ocean. http://www.wavedragon.net/technology/principles.htm

In Norway, a tidal energy test program has been “considerably extended” for reasons that were not disclosed by the developer, Hammerfest Strom AS. The company originally planned to install its prototype, which resembles a wind turbine, in a narrow strait in Kvalsundet in northern Norway. Although the prototype has been built, its installation in the strait has been delayed indefinitely. [sorry this link is no longer available]

Britain is also supporting wave and tidal energy projects. In January, the United Kingdom’s Energy Minister, Brian Wilson, awarded 3.7 million pounds (nearly 6 million U.S. dollars) to two companies: Wavegen and Tidal Hydraulic Generators Ltd. [sorry this link is no longer available]


University of Idaho Sweeps SAE Clean Snowmobile Challenge

The University of Idaho took first place in the Society of Automotive Engineers’ (SAE) Clean Snowmobile Challenge, held last week at Michigan Technological University (MTU). The annual event marked its fourth year of challenging university students to produce a snowmobile that is clea
ner, more fuel efficient, and quieter than existing models, while still being fun to ride. The University of Idaho took first place in the event’s major categories — emissions, noise, and fuel economy — while also performing well in the performance categories. The team used a BMW four-stroke motorcycle engine to achieve its impressive win. See the SAE press release at: [sorry this link is no longer available]

The SAE Clean Snowmobile Challenge holds particular significance in light of last week’s decision by the National Park Service (NPS) to limit snowmobile use in Yellowstone and Grand Teton National Parks and in the John D. Rockefeller, Jr. Memorial Parkway, which connects the two. By the winter of 2004, all snowmobiles entering those parks must use the best available technology, effectively banning the use of snowmobiles with two-stroke engines in the parks. [sorry this link is no longer available]
Considered impractical just a few years ago — when the SAE Clean Snowmobile Challenge began — snowmobiles with four-stroke engines are now being produced by several manufacturers. In fact, Yamaha Motor Corporation, U.S.A. recently introduced a four-stroke model that won SnowGoer Magazine’s 2003 Sled of the Year award. http://www.yamaha-motor.com/news/dynamicnews.asp?aID=196&LID=6
