Efficient Use of Electricity

Advanced technologies offer an opportunity to meet the world's future energy needs while minimizing the environmental impact. Both suppliers and consumers of electricity can benefit from the savings

By Amory B. Lovins, Arnold P. Fickett and Clark W. Gellings

Energy for Buildings and Homes

New technologies-superwindows, compact fluorescent lights and automated-control systems-combined with other strategies, such as shade trees and light -colored buildings, could reduce building energy bills by half

By Arthur H. Rosenfeld and Rick Bevington

Energy for Industry

Industrial processes consume two fifths of the developed world's energy. Efficiency improvements have steadily cut that share and promise to continue

By Daniel Steinmeyer and Marc H. Ross

Energy for Motor Vehicles

They consume a growing share of the world's oil supply and are also major polluters. Efficient designs, alternative fuels and rational transportation systems can help solve the problem

By Deborah L. Bleviss and Peter Walzer

Energy for the Developing World

By mixing efficient end-use technologies with modest increases in generating capacity, developing countries can affordably obtain the energy they need without ruining the environment

By Amulya K. N. Reddy and Jos Goldemberg

Energy for the Soviet Union, Eastern Europe and China

Economic reforms and new technology may allow the centrally planned economies and the emerging democracies to develop without further harm to the environment

By Alexei A. Makarov, William U. Chandler and Zhou Dadi

Energy from Fossil Fuels

Until other energy sources supplant coal, oil and natural gas, the technological challenge is clear: extract maximum energy from the old standbys while minimizing harm to the environment

By Manoj K. Sanghvi, Roddie R. Judkins and William Fulkerson

Energy from Nuclear Power

Atomic energy's vast potential can be harnessed only if issues of safety, waste and nuclear-weapon proliferation are addressed by a globally administered institution

By Wolf Hfele

Energy from the Sun

Various forms of solar energy, including wind and biomass, offer environmentally benign ways to generate electricity and make fuels. Some technologies will be cost-competitive before the year 2000

By Carl J. Weinberg and Robert H. Williams
