About 90% of conventional grid electricity in the United States derives from non-renewable energy sources, namely: coal (45%), natural gas (23%), and nuclear (20%) [1]. In varying degrees, non-renewable energy resources impact the environment, public health and economic productivity due to the effects of mining and drilling, transportation, combustion, and resulting pollution and waste streams [2]. By comparison, wind is both renewable and clean.
Investment in wind projects leads to economic benefits and work for wind turbine manufacturers, landowners, construction companies and workers, local businesses which support construction and operations, and the municipalities where facilities are built. In addition, the final delivered price of wind energy is competitive with other sources and helps stabilize electricity rates through fixed long-term contracts.
