Many liberal and libertarian thinkers have criticized NEPA and expressed support for the bill, saying it would speed up clean energy. The free-market R Street Institute, for instance, has found 40 percent of the active NEPA reviews at the Department of Energy are for clean energy projects, compared to 15 percent for fossil fuels. The liberal columnist Ezra Klein, writing for the New York Times, said that the bedrock environmental law is one of many “checks on development that have done a lot of good over the years but are doing a lot of harm now.”
