Quantifying the health and environmental benefits of wind power to natural gas

► This study compares the benefits of wind energy with natural gas. ► The Altamont Pass windfarm will avoid $560 million to $4.38 billion in externalities. ► The Sawtooth wind farm will produce about $18 million to $104 million in human health and climate benefits. ► Natural gas prices rise by 1.5-11.8 cents/kWh if they include the cost of such externalities.
