NEW YORK (AP) — Companies that generate electric power with anything other than coal — and companies that produce cleaner fuels or efficiency technologies — are likely to benefit from the Obama Administration’s new proposed limits on carbon dioxide emissions from power plants.

The biggest U.S. natural gas producer, Exxon Mobil, will likely see higher demand for its fuel, which emits half the carbon dioxide as coal. The biggest nuclear power generator, Exelon, and biggest wind farm operator, Next Era Energy, may fetch higher prices for their carbon-free power. Companies that sell wind turbines, solar panels, or energy efficiency technology — such as General Electric, Siemens, First Solar and SunPower — may also come out winners.
