Abstract
Amory Lovins of Rocky Mountain Institute in Snowmans, Colorado reported at the Dahlen workshop on 'Limiting the Greenhouse Effect: Options for Controlling Atmospheric CO{sub 2} Accumulation' that his institute has identified 50 energy-saving technologies that, if implemented worldwide, would cut global energy use in half. In the three sectors of energy use, lighting, motors, and appliances, the possibility of saving two-thirds of the total U.S. demand for electricity exists now according to Lovins. Compact fluorescent tubes could save 10% electricity, new electronic speed control systems, new materials and designs, new drive trains, and new bearings for electric motors could save nearly 60% of the electricity used by motors, and better insulation could make refrigerators (the most energy consumptive appliance except space and water heaters) as much as 90% more efficient. Price seems to be the overall barrier to realizing these energy savings. Some incentives for energy savings are being offered by utilities, and with massive energy efficiency, the global warming might be mitigated.
