Two new reports find considerable potential in energy efficiency for significant reductions in US greenhouse gas emissions, and that cost savings should far outweigh the price of implementation.
According to a recent report by McKinsey & Company, a comprehensive national approach to energy efficiency would lead to energy savings of $1.2 trillion by 2020. Identifying energy efficiency as "an emissions-free energy resource," the report forecasts an abatement of greenhouse gas (GHG) emissions of 1.1 gigatons per year, "the equivalent of taking the entire U.S. fleet of passenger vehicles and light trucks off the roads." The McKinsey report found that these savings could be accomplished with a ten-year investment of $520 billion.
