The 2007 U.S. Department of Energy (DOE) Annual Report on the development and trends of wind power reports that the cost of wind power is nearly very competitive with those of conventional power technologies. And this does not account for the environmental and health benefits of using a non-polluting source of energy. It is expected that over time, wind energy cost will decrease as most conventional generation technology costs continue to increase. Since 2002, the cost of turbines has been on the rise because of increase cost of input material, energy prices, and in some cases, shortages in certain turbine components13. Large-scale wind farms can be installed for between $1,000 and $2,000 per kilowatt. The cost of electricity produced from wind farms can be attributed to the annual capacity factor, location, wind quality, and installation and maintenance costs. The cost per kilowatt for small-scale wind turbines is still relatively high, with costs up to $3,000 per kilowatt. However, the cost per kW decreases as the size of the turbine increases. Wind availability at a site also influences cost. Wind turbines installed in very windy locations generates less expensive electricity than the same unit installed in a less windy location. It is therefore important to assess wind speeds at the potential site during the planning stage
