The U.S. Department of Energy (DOE) is quitting the hydropower and geothermal power research business -- if Congress will let it. Declaring them mature technologies" that need no further funding, the Bush administration in its FY 2007 budget request eliminates hydropower and geothermal research. "What we do well is research and funding of new, novel technologies," says Craig Stevens, chief spokesman for the DOE. "I'm just astonished the department would zero out these very small existing budgets for geothermal and hydro," says V. John White, executive director of the Center for Energy Efficiency and Renewable Technologies. "These are very important resources for our energy future that could replace the need for a lot of coal-fired power plants." Indeed, the costs of lost opportunities from dropping such research could be enormous in the long run. Geothermal holds vast potential -- at least 30,000 megawatts of identified resources developable by 2050. Meanwhile, the more than 5,400 potential "small hydro" power projects could produce about 20,000 megawatts of power, a DOE study in January found. And most would require no new dams at all, shunting a portion of a small river's flow to one side to make electricity. Others would add turbines to dams that don't have them yet. Together, high-tech hydropower and geothermal resources could contribute at least enough power to replace more than 100 medium-size coal-fired power plants with emissions-free electricity.
