The energy efficiency standards in the bipartisan Senate energy bill will save so much energy in the coming years that by 2010, the electricity savings will total 12 GWh and will reduce peak electric demand by the output of 12 new 300-MW power plants. By 2020, the savings will total 66 GWh and reduce peak demand by the output of 75 new 300-MW plants. By 2030, the savings will equal 96 GWh and reduce peak demand by the output of 108 new 300-MW plants.
