The Obama administration proposed on Tuesday the first ever standards to cut carbon dioxide emissions from new power plants, a move likely to be hotly contested by Republicans and industry in an election year. The Environmental Protection Agency proposed the long-delayed rules that limit emissions from all new US power stations, which would effectively bar the building of any new coal plants.
While the rules do not dictate which fuels a plant can burn, they would require any new coal plants essentially to halve carbon dioxide emissions to match those of efficient gas plants. "We're putting in place a standard that relies on the use of clean, American made technology to tackle a challenge that we can't leave to our kids and grandkids," EPA Administrator Lisa Jackson said in a release.
Republicans have already turned to the courts to forestall other EPA measures they say will drive up power costs for homeowners and businesses that are struggling to recover from the weak economy. Some Democrats from energy-intensive states are also likely to oppose the rules. The EPA's overall clean-air efforts have divided the power industry between companies that have moved toward cleaner energy, such as Exelon and NextEra, and those that generate most of their power from coal, such as Southern Co and American Electric Power.
Under the rules, coal plants could add equipment to capture and bury underground for permanent storage their carbon emissions. The rules would likely give any new coal plants time to get those systems running, by requiring that they average the emissions cuts over decades.
Supporters of the rules argue that the industry has been moving away from coal and towards natural gas because of low prices and abundant supply. The portion of US electricity fired by coal has slipped from about 50 percent to 45 percent in the last few years.
