I'd like to send this letter by lopressor 25mg One of the biggest contributors to slowing emissions in the United States, for example, is the meteoric rise of shale gas as an electricity source. For every bit of electricity it produces, natural gas emits about half as much carbon dioxide as does coal, the fuel that U.S. shale gas is largely supplanting. Yet the rise of shale gas isn’t due to some anti–global warming Manhattan Project. It’s the culmination of two forces: innovative and dogged oil companies out to make a fortune, and federal research spending designed to boost domestic fossil fuel supplies and reduce imports from the Middle East.
