When Americans think about increased energy efficiency, they conceive of it in terms of individuals buying CFL bulbs or energy-efficient appliances. But a new report from the American Council for an Energy-Efficient Economy (ACEEE) urges that equal attention be paid to large-scale energy efficiency savings that could cut U.S. energy consumption over 50 percent, save consumers more than $300 to $400 billion per year, and add almost two million jobs by 2050.
