Or maybe not. LCD's use less energy than do CRT's of comparable size. But properties are replacing much smaller CRT's (20-27 inch) with larger LCD's (32-37 inch). The size increase serves to negate any savings of energy and, indeed, the larger-sized LCD's may use more energy than the smaller CRT's. http://www.sierraclub.org/howgreen/screen/answer.asp
