MIT and the IEA both have newly released reports exploring the potential for and impact of a major expansion in global usage of natural gas, given the current re-evaluation of global supplies. The IEA takes a more conventional approach, assessing the impact on the penetration of vehicles burning gas as their fuel. Earlier post.)
The decrease was driven by the economic downturn, combined with a significant switch from coal to natural gas as a source of electricity generation, according to the EIA. The EIA projects that fuel switching in the electric power sector and declines in industrial use will lead to a 7.9% Natural Gas.
Rice University researchers have determined a more effective way to use natural gas to reduce climate-warming emissions would be in the replacement of existing coal-fired power plants and fuel-oil furnaces rather than burning it in cars and buses.
In the United States, emissions associated with the consumption of petroleum fuels—motor gasoline, distillate, jet fuel, and more—have consistently made up the largest portion of CO 2 emissions.
