Item #d89jul35

The following constitute a special section in Science, 244(4902), Apr. 21, 1989.

Item #d89jul36

"Photovoltaics Today and Tomorrow," H.M. Hubbard (Solar Energy Res. Inst., Golden CO 80401), 297-304.

Presents the evolution and status of photovoltaic (PV) technology. Explains significant advances in the development of low-cost PV materials coupled with innovative device designs that result in efficiencies ranging from 22.8% to 31%. Advances in marketing and distribution in the next two decades should make it possible for PV electrical systems to become one of the world's preferred technologies for generating electrical energy.

Item #d89jul37

"Changing Prospects for Natural Gas in the United States," W.M. Burnett (Gas Res. Inst., 8600 West Byrn Mawr Ave., Chicago IL 60631), 305-310.

Natural gas has emerged as one of the primary options for providing environmentally clean energy because it has a large resource base, it is the cleanest burning fossil fuel and it can be used efficiently. New engine, combustion and energy conversion technologies are emerging that will result in the use of natural gas for electric generation, emissions reduction, transportation, and residential and commercial cooling.

Item #d89jul38

"Improving the Efficiency of Electricity Use in Manufacturing," M. Ross (Phys. Dept., Univ. Michigan, Ann Arbor MI 48109), 311-317.

Analyzes the recent history of energy use by manufacturers and discusses future energy use. Adoption of new technologies for increasing the efficiency of electricity use is likely to continue to be as important as new modes of electrification. This implies that effective electric energy efficiency will be stable, but the outcome depends on electricity pricing and private as well as public policies.

Item #d89jul39

"Improved and Safer Nuclear Power," J.J. Taylor (Nuclear Power Div., EPRI, Palo Alto CA 94303), 318-325.

Summarizes the recent issues facing nuclear power development, emerging design features, and the current progress of three reactor systems of primary interest in the United States--those cooled by ordinary (light) water, by liquid metal and by gas. Modular design concepts and design standardization are also used to reduce construction time and engineering costs, thus making nuclear power competitive with alternate methods.
