Electrical Energy - Essay Example This have made the technologists to search for more energy efficient practices and hence could achieve major break through in energy efficiency as it is reported that the efficiency have really doubled since 1954. The reports available show that the fuel mix has more or less remained constant since 1980 (Lave, 291). According to the reports of U.S. Department of energy, half the quantity f electricity generated is from coal, nuclear plants account for 20 percent of the generated electricity, while hydroelectric plants contributes 7 percent and finally renewable energy and petroleum products account for 2 percent each.
