Environmental Impacts of Wind Power
Summary
The document examines the environmental footprint of wind power, noting that while it is a clean energy source, it has specific impacts on land use, wildlife, and local communities. It highlights that land-based facilities in the US use between 30 and 141 acres per megawatt, though permanent disturbance is less than 1 acre per megawatt. Wildlife impacts, particularly bird and bat collisions, are described as relatively low and manageable through better siting and operational adjustments. Public health concerns regarding sound and vibration have not been found to have adverse effects in studies from Canada and Australia. Finally, the document notes that wind power's life-cycle global warming emissions (0.02 to 0.04 pounds of CO2e/kWh) are significantly lower than those of natural gas or coal.
Key insights
- Land use for large wind facilities in the United States ranges from 30 to 141 acres per megawatt of capacity, but permanent disturbance is limited to less than 1 acre per megawatt, with temporary construction disturbance under 3.5 acres per megawatt.
- While wind turbines cause bird and bat deaths through collisions, air pressure changes, and habitat disruption, a National Wind Coordinating Committee review concluded these impacts are relatively low and do not threaten species populations.
- Government and industry studies in Australia and Canada indicate that sound and vibration issues associated with wind turbines do not adversely affect public health.
- Wind power has significantly lower life-cycle global warming emissions than fossil fuels, with estimates between 0.02 and 0.04 pounds of CO2 equivalent per kilowatt-hour, compared to 0.6 to 2 pounds for natural gas and 1.4 to 3.6 pounds for coal.
