Sens. Mark Udall, D-Colo., and Tom Udall, D-N.M., are trying again on legislation to force utilities to get a quarter of their power from renewable sources by 2025.
"A national [renewable-energy standard] will get America running on homegrown clean energy, create almost 300,000 new jobs, and help revitalize our rural communities—all while fighting global warming," Tom Udall said in a statement.
Mark Udall was among the leaders who helped push for Colorado's first-in-the-nation renewable standard in 2004.
This isn't the first drive for such legislation on the federal level by the two senators, who are cousins. The Hill notes they've been advocating for the standard since 2002, although previous attempts failed.
