America’s big shift to green energy has a woolly mammoth problem

Transmission lines in the US need to be increased threefold, but faces pushback from fossil conservation and green groups

America’s renewable energy drive needs more than a million miles of new transition lines but emerging resistance includes opponents worried about building them in one of the country’s richest areas of ice-age fossils.

The Greenlink West project would build a 470-mile-long transmission line bringing clean electricity north to Reno in Nevada, but it cuts through an area containing everything from woolly mammoth tusks to giant sloths to ancient camels.
