Report  Calls Energy Efficiency an "Invisible" Energy Boom (From: eere news) 
Energy  efficiency has met three-quarters of the U.S. demand for new energy services  since 1970, but it goes relatively unnoticed amid a focus on energy production,  according to a new report from the American Council for an Energy Efficient  Economy (ACEEE). The report notes that the U.S. economy uses half as much energy  per unit of economic output than it did back in 1970, making energy efficiency  the "fastest-growing success story of the last 50 years."
 
The  report focuses specifically on 2004, when roughly $300 billion was invested in  energy efficiency in the United States, supporting 1.6 million jobs. That  investment was triple the amount invested in the energy supply infrastructure,  and it generated 1.7 quadrillion Btu, or quads, of energy savings. For  comparison, the United States currently consumes about 100 quads of energy. The  2004 savings were roughly equal to the combined energy output of 40 mid-sized  coal-fired power plants. Nearly 60% of total energy efficiency investments were  made in buildings, including homes, commercial buildings, and energy efficient  devices, while about a quarter of the investments went toward industrial energy  efficiency improvements. Only 11% of the investments went towards improving the  fuel economy of cars, trucks, aircraft, and other forms of transportation,  despite the fact that the transportation sector consumes 28% of the U.S. energy  supply.
 
The  ACEEE report also finds plenty of room for improvement, noting that the United  States can reduce energy consumption by an additional 25%-30% over the next  quarter century through cost-effective energy efficiency measures. In an  environment of accelerated market transformation and rapid growth in energy  efficiency, the total annual investments in energy efficiency could approach  $400 billion by 2030, according to the report.
