U.S. Energy Secretary Steven Chu announced that 32 projects in 14 states would share $38 million over the next three years to develop geothermal energy technologies.
The International Energy Agency this summer recommended that governments introduce incentives that would encourage the commercial development of geothermal technologies and payments to third parties that introduce alternative energy to the grid.
Another $150 million in loan guarantees was awarded to Massachusetts solar energy company 1366 Technologies Inc. to develop a silicon-based wafer that Chu said could significantly reduce the costs of solar manufacturing.
Twenty states will share $43 million over the next five years to develop 41 wind energy systems, the Energy Department said.
"Through these awards, the Department of Energy is developing the critical technology and knowledge base necessary to responsibly develop this resource, enhance our energy security and create new clean energy jobs," Chu said.
U.S. President Barack Obama outlined a goal of generating 80 percent of the nation's electricity through clean energy resources by 2035.
