The ACEEE report, The Size of the U.S. Energy Efficiency Market:Generating a More Complete Picture, further suggests the US cancost-effectively reduce energy consumption by an additional 25% to30% or more in the next 20 to 25 years. The report was preparedwith support from the Civil Society Institute along with theKendall Foundation and the North American Insulation ManufacturersAssociation.

Describing the contributions of efficiency as "often unnoticed"and "invisible," the report notes that the "nation is not aware ofthe role that energy efficiency has played in satisfying ourgrowing energy-service demands." Since 1970, energy efficiency hasmet about three-fourths of the demand for new energy-relatedservices while conventional energy supply has covered onlyone-fourth of this demand.

It adds, "Efficiency can make an even larger contributiontowards stabilizing energy prices and reducing greenhouse gasemissions--should we choose to fully develop it." Total investmentsin more energy efficiency technologies could increase the annualenergy efficiency market by nearly $400 billion by 2030, resultingin an annual efficiency market of more than $700 billion and totaladditional investments from now until 2030 of nearly $7trillion.
