Natural gas is the cleanest-burning fossil fuel; efficient use of natural gas can result in substantially lower emissions of global warming pollution than many alternatives. But this doesn't mean we need to drill more natural gas in wild places.

This 2007 study by McKinsey and Company, co-sponsored by NRDC, concludes that the United States can significantly reduce greenhouse gas emissions at marginal costs - provided strong, concerted action is taken quickly.

NRDC outlines six energy-sector opportunities that can help America reduce global warming pollution.

This series of papers by NRDC efficiency experts measures the energy use of commonly owned electronics, including televisions, cell phones and cable boxes, to see how much energy could be saved through product innovation. Each paper presents energy saving options and recommendations.
