In addition, the development of renewable energy resources is widely supported by the public and our customers.”Rick Walker, director, Renewable Energy Business Development, AEP Energy Services, Inc., Dallas, TX “Our customers wanted this wind program and it was our job to deliver it. It has turned out to be a huge source of community pride. The turbines are a visible landmark showing the Moorhead Community’s commitment to a better world for our children.”Christopher Reed, Moorhead Public Service, Moorhead, Minnesota “Wind is a homegrown energy that we can harvest right along side our corn or soybeans or other crops. We can use the energy in our local communities or we can export it to other markets. We need to look carefully at wind energy as a source of economic growth for our region”David Benson, Farmer and County Commissioner, Nobles County, Minnesota “In evaluating the potential of wind energy generation, Native Americans realize that wind power is not only consistent with our cultural values and spiritual beliefs, but can also be a means of achieving Native sustainable homeland economies.”Ronald Neiss, Rosebud Utility Commission President, Rosebud Sioux Reservation, South Dakota KotzebueKotzebueElectric Association, Electric Association, AlaskaAlaskaBrad Reeve, General Manager, Kotzebue Electric Association“It is becoming clear that wind energy will play a major role in the national generation mix. In Kotzebue, Alaska, wind energy provides between 5%-7% of the total energy needs and we plan to add more. There are potentially 70 to 90 communities that could reduce their energy costs by adding wind energy. This makes it extremely important for utilities to learn all they can about wind’s ability to provide safe, reliable, cost-effective electricity to their members.” KotzebueKotzebue, Alaska, Alaska• Application: Village power system• 11 MW diesel power plant• Operating with 10 turbines since 1999• 2MW average load, min load 700kW.
