Proposes that human comfort could be provided in otherwise chilly surroundings by filling the occupied space with electromagnetic energy of cm wavelength. Considerable energy savings could be realized from the resultant ability to lower interior temperatures and maintain comfort in the building. (Author/RE)

The energy required to build and install solar space- and water-heating equipment is compared to the energy saved under two solar growth paths corresponding to high and low rates of solar technology implementation. (Author/RE)

Basic concepts of thermochemical hydrogen generation processes are summarized. Criteria for screening and selecting processes are described. (RH)

Analyzes problems of providing sufficient electrical power in terms of inefficiency of industry and of the conflict between need for power and need for environmental quality. Suggests ways of slowing the growth in demand, and indicates needed research into energy production. (EB)

Municipal solid waste disposal is becoming complex as costs, wastes, and environmental restrictions increase. Recovery and recycling of materials presents problems of financing, ownership, and operation, technology, and marketing. Energy and materials recovery offers long-term economic and environmental incentives in terms of growing shortages and…

An industrial development involves the conversion of biomass, through fermentation, to useful chemical products and the gasification of municiple wastes to produce steam for electricity generation. These gases may also serve as chemical feedstocks. (Author/MA)

Advocates the development of a hydrogen fuel economy as an alternative to the predominately electric economy based upon nuclear plants and depleting fossil fuel supplies. Evaluates the economic and environmental benefits of hydrogen energy delivery systems in the residential and transportation sectors. (JR)

Discusses Britain's energy policies and changing energy sources since World War II. North Sea natural gas and oil should prevent shortages in the near future. Planning is complicated by Britain's entry into the European Common Market, questionable progress in nuclear production, and the uncertain availability of Middle Eastern oil. (JR)

Government support of coal liquefaction Research and Development has created the conditions that make possible the development of needed technology. With the proper government incentives, pioneer plants will lead to lower costs, and this, plus rising prices, will create the conditions necessary to develop a multi-plant industry. (Author/MA)

The development of fuels from biomass can lead naturally to dispersed facilities that incorporate food or materials production (or both) with fuel production. The author analyzes possible systems based on sugarcane, corn, and guayule. (Author/MA)

Describes recent research that has made solar energy economically competitive with other energy sources. Includes solar energy building architecture, storage systems, and economic production data. (MLH)

American industry in the 19th century switched from wood to coal as its primary energy resource. The history of this switch is reviewed, along with the history of preceding similar trends in Europe and later trends in the switch from coal to oil and gas. (Author/MA)

The water consumption requirements for a variety of energy options are presented, and comparative judgments drawn. Attention is focused on problems resulting from synthetic, gaseous, and liquid fuel production. Scenarios describing possible future levels of coal and electricity use are analyzed. They point to the importance of water supply…
