Efficiency is frequently described as the “low-hanging fruit” for cutting greenhouse gas emissions and reducing fossil fuel consumption. Energy efficiency improvements can meet a substantial portion of new U.S. energy demand and are relatively easy, cheap, and within the scope of current technology. A number of states have already adopted an “energy efficiency resource standard,” or EERS requiring utilities to reduce electricity demand, and these standards are already creating electricity savings. New legislation proposed in Congress by Rep. Edward Markey (D-MA) would build on these successes by enacting a federal EERS that would reduce national energy demand, save businesses and households money, and reduce global warming pollution.
