	Laptop Computers: How Much Energy Do They Use, and How Much Can We Save? (*.pdf File Size: 931776 bytes) -- Posted 2/6/2004 NRDC and Ecos Consulting assessed the approximate energy efficiency differences between laptop and desktop computers to determine how much energy the U.S. might save by switching to more efficient designs. Also discussed are ways to characterize computer efficiency on a component basis and system basis. The report concludes with recommendations for future policy and research activities.
	NRDC Project on Power Supply Efficiency (*.pdf File Size: 1164421 bytes) -- Posted 8/11/2003 An ECOS Consulting report on hidden opportunities for energy savings in power supplies conducted for the Natural Resources Defense Council.
	CEC Project on Power Supply Efficiency in the Active Mode -- Posted 8/7/2003 The California Energy Commission, through its Public Interest Energy Research (PIER) program, has awarded funding to a collaborative effort to improve internal and external power supply efficiency. This collaborative effort includes Ecos Consulting, Electricity Innovation Institute (E2I), and EPRI Solutions Inc.. The goals of the project are to establish a consensus test method, refine estimates of energy use and savings opportunities, build relationships with industry, establish a national design competition, and make policy recommendations for the state of California.
