Background

This test is being conducted as part of the DOE's Small Wind Turbine Field Verification Program. The primary purpose of this program is to provide consumers, manufacturers, and host site organizations with an independent assessment of the performance and reliability of small wind turbines manufactured in the United States. As part of the DOE/GO Field Verification Program, each turbine must pass a suite of IEC tests, including duration, system safety and function, power performance, and noise tests.

The Bergey Excel test turbine, located at the National Wind Technology Center (NWTC), is owned by AWS Scientific, Inc. This turbine was erected at the NWTC in October 1999 and tested to determine power performance characteristics. In March 2002, the original blades were replaced with a new set of blades, and this second test was conducted.

Renewable Energy 101

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable. The usage of renewable energy sources is very important when considering the sustainability of the existing energy usage of the world. While there is currently an abundance of non-renewable energy sources, such as nuclear fuels, these energy sources are depleting. In addition to being a non-renewable supply, the non-renewable energy sources release emissions into the air, which has an adverse effect on the environment.
