Renewable energy refers to energy generated from natural resources such as sunlight, wind, rain, tides, and geothermal heat which are naturally replenished. Wind power is growing at a rate of 30% annually with a worldwide installed capacity of 121,000 MW in 2008. In 2009, the U.S. broke all the records by installing nearly 10,000 MW of new generating capacity (enough to power 2.4 million homes). These new projects place wind power neck and neck with natural gas as the leading source of new electricity generation in the U.S. Together, these two sources account for about 80% of the new capacity added in the country last year. While most of these projects are large, utility scale projects, small on-site or community renewable energy projects are significantly on the rise. In fact, community wind is one of the fastest growing sectors in the wind industry today. In November of 2009, of the nearly 32,000 MW of installed wind capacity in the U.S., just over 1,400 MW were community owned.
