A Learning Investment-based Analysis of the Economic Potential for Offshore Wind: The Case of the United States

This report finds that an investment between $18.5 and $52 billion from 2014 to 2030 may be sufficient to enable offshore wind in the United States to compete with conventional and alternative renewable energy sources. Additionally, the investment would produce only modest increases in the average consumer’s monthly bill – in the range of $0.25 to $2.08 if the cost is spread across all electricity consumers in the United States, and between $0.51 and $4.29 if the cost is confined to only those states where offshore wind would be deployed, primarily in the Atlantic coast and Great Lakes region.

This report was prepared by The Brattle Group for the Center for American Progress, the US Offshore Wind Coalition, the Clean Energy States Alliance, and the Sierra Club.
