U.S. Energy Secretary Steven Chu announced that 31 tribal energy projects would receive federal funds during the next two years as part of a partnership with tribal nations.
The Energy Department said the projects would help tribal groups advance clean energy technologies while promoting economic development.
"Tribal nations are well-positioned to take advantage of the benefits of clean energy and energy-efficient technologies," Chu said in a statement.
Around $2 million of the funding targets improvements in the energy efficiency of buildings. Another $2 million focuses on developing the workforce needed for clean-energy development. The remaining funds would help reduce tribal heating and cooling costs by at least 30 percent.
"Projects such as these will save energy and money, create long-term, clean-energy jobs and spur economic development in tribal communities nationwide," Chu said.
