The Department of the Interior expects to approve seven major, renewable-energy transmission projects on western federal lands by the end of next year, part of the administration's effort to step up use of wind and solar power. Finding sites for new grid infrastructure has been a major obstacle to the Obama administration's plans to expand renewable-energy production. Many people and local governments oppose placing transmission projects, which help channel electricity generated by renewable-energy sources to consumers, in their backyards, citing environmental, safety and other concerns.
