After a description of the current constraints on energy growth, the author concludes that solar energy is by far the most attractive energy source. The constraints described fall into the following categories: heat limits, pollution, material constraints, financial constraints, and political limits. (BM)

This paper, one of a series published by the Worldwatch Institute to identify and focus attention on global problems, is adapted from the author's book, "Rays of Hope: The Transition to a Post-Petroleum World." The author examines the current energy problems of the world, and determines that the energy patterns of the past are not the prologue to…

This publication proposes a timetable for converting the world economy to solar energy. The contents include: (1) A solar-powered world by 2025; (2) Heating and cooling; (3) Renewable fuels; (4) Electricity; (5) Getting there from here; and (6) Notes. Numerous facts are presented within these sections. International solar research programs are…

A discussion of a global timetable for conversion to solar energy uses which includes examinations of intermediate energy sources like ethanol, wind, and methane is given. (MDR)

This publication is the sixth in a series of papers on global environmental issues. This paper evaluates the future of nuclear power, subjecting it to several tests: (1) economics; (2) safety; (3) adequacy of fuel supplies; (4) environmental impact; and (5) both national and international security. Section headings include: (1) The nuclear fuel…

Focusing on the need for energy to sustain economic development on a long-term basis, the document examines energy options of the post-petroleum era in developing nations. Nuclear power and solar power are the most important among proposed alternative energy sources. Limited applicability of nuclear technology to the Third World is discussed.…
