One transmission line's ups and downs
Wyoming – The Obama Administration says it wants to see 25 percent of the country's electricity coming from renewable sources by 2025. But to boost renewable energy's share of total energy consumption - we have to figure out how to move it from here to there. For the most part, the places in the country that are the best sources of wind and solar energy aren't close to the places that use the most electricity. And wind and solar power are intermittent - generated when the wind is blowing and the sun is shining. That calls for a different kind of transmission system than the U.S. currently has. And that's a big challenge. Wyoming Public Radio's Molly Messick explains why - with this story of one transmission line's ups and downs.
