Clean energy incentives in the new spending package signed this week will trim America’s emissions of heat-trapping gases by about 1.1 billion tons by 2030, a new Department of Energy analysis shows. The first official federal calculations say that between the bill just signed and last year’s infrastructure spending law, the U.S. by the end of the decade will be producing about 1.26 billion tons less carbon pollution than it would have without the laws. That saving is equivalent to about the annual greenhouse gas emissions of every home in the US. The Energy Department analysis finds that with the new law by 2030, U.S. greenhouse gas emissions should be about 40% lower than 2005 levels, which is still not at the U.S. announced target of cutting carbon pollution between 50% and 52% by the end of the decade. …Most of the projected emissions reductions come in promoting… solar and wind power and electric vehicles.
