In mid-December, the U.S. Interior Department announced plans to auction off more than 79,000 maritime acres off the coast of Maryland for wind energy development. Two leases in 2013 generated more than $5 million in bids from investors, but the industry faces an uncertain future as the private sector takes the lead in renewable energy development.

The Interior Department's Bureau of Ocean Energy Management said the wind energy potential off the Maryland coast may be significant.  More than 79,000 acres will be put on the auction block for wind energy developers next year, and the BOEM estimates the area could support more than 850 megawatts of power if the region is developed fully.

Wind is a premier source of renewable energy in the United States, beating out hydroelectric power as the primary alternative resource for consumers. While renewable energy still pales in comparison to fossil fuels, wind capacity inland has increased from 1.5 gigawatts in 1992 to 45 GW by the end of 2011, providing more than 3 percent of total electricity generation.

While there are no commercial wind energy developments offshore, that's about to change. In 2013, two lease sales for acreage in the Atlantic Ocean generated $5.4 million in bids from wind energy developers. Deepwater Wind New England, which bet $3.8 million on the wind potential offshore Rhode Island and Massachusetts, said nearly 350,000 utility customers will be getting their annual energy needs met by wind by 2018.

For Maryland, state Gov. Martin O'Malley said wind energy was about more than just moving away from fossil fuels.

"The development of offshore wind will drive economic development in Maryland, create high-quality, family-supporting jobs for Maryland residents and play a major role in reducing emissions and protecting the environment," he said.

But the sector faces an uncertain future. The implementation in 1992 of a wind energy production tax credit helped provide a solid foundation under the sector. The tax credit, however, has often found itself on the chopping block of lawmakers debating future budgetary policies. The incentive barely survived last year's budget imbroglio, and faces an uncertain future before it expires again by the end of this year.

Supporters of the fossil fuel industry say wind energy is a "boutique" energy resource that's expensive even with the federal government's tax credit. The wind industry, meanwhile, credits the tax incentive for a robust year, one in which 68.3 MW of wind power was made available during the third quarter. The latest budget deal, proposed by Rep. Paul Ryan, R-Wisc., and Sen. Patty Murray, D-Wash., left the wind tax credit on the cutting room floor. Without the federal incentive, next year's wind energy auction off Maryland's shore may be the bellwether for the sector in the United States.
