The U.S. Department of Energy has announced plans to provide $28 million in grants to seven proposed offshore wind projects, a financial commitment the Obama administration hopes will provide a boost to a green energy sector that has yet to gain a foothold in American waters. Each of the seven projects — located in Maine, New Jersey, Virginia, Texas, Ohio, and Oregon — will receive $4 million during the engineering, design, and permitting phases. Eventually, if Congress approves, three of the projects could each receive up to $47 million over four years for later phases, including siting, construction, and installation. In contrast to Europe, where offshore wind projects are growing, no offshore wind projects are currently being built in the U.S., although two projects have been approved in Massachusetts and Rhode Island. The American Wind Energy Association (AWEA) is urging lawmakers to extend the Production Tax Credit, a 2.2-cent per kilowatt-hour incentive that has helped the land-based wind sector to surge past 50,000 megawatts but is set to expire at the end of the year.
