Discusses the feasibility of utilizing continuous sources of of energy, particularly solar and wind energy. Outlines an energy plan for Denmark, which would supply all of Denmark's energy needs by the year 2050. (MLH)

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)

Presents the position that the federal government will have to take a direct hand in holding down demand for energy while promoting new sources of supply. Increased consumption and the dim short-term prospects for major alternatives to oil are cited as major problems. (GS)

Shortcomings of the usual definition of energy efficiency are identified. Suggestions are general for better use of fossil fuels. Studies done by the American Physics Society (APS) are discussed and recommendations made for an improved definition of energy efficiency are described. (Author/EB)

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)

Summarizes factors that will create severe energy shortages by 1980. Indicates that conservation is not enough, and the quickest path toward relief is the expansion of surface mining of low-sulfur coal in the Rocky Mountain states. (GS)

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…

Discusses noneconomic factors limiting the total power that can be extracted from the wind. These factors are examined with a macroscopic approach. Some general conclusions are also reached regarding the sites that would have to be utilized and the usable wind energy potentials. (HM)

Recaps government action in the areas of land use, strip mining, and drinking water legislation. Outlines the potential conflict between the development of energy resources and environmental values. (GS)

Summarizes the criticisms of the Office of Science and Technology (OSTP) review committee. Emphasizes research deficiencies in most of the major energy programs. (MA)

Considers our scientific knowledge of environmental matters inadequate. New efforts related to solar energy, energy conservation, environmental determination, water quality, and chemical pollutants are suggested. (HM)

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)
