Conservation of energy is becoming a major concern. Author describes many uses of energy in homes, offices and other places which can be modified. (PS)

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 various ways in which the demand for energy could be decreased, focusing not so much on discouraging demand by increasing prices, as on reducing energy consumption by improving efficiency of energy utilization in buildings and in industry. (JR)

More intensive and varied use of the oceans and their resources requires a more comprehensive legal regime than previously. Three years of preparatory work have been completed for the Law of the Sea Conference. It appears that the coastal nations will gain some form of jurisdiction over fisheries and mineral resources off their shores. (RH)

Discusses problems facing the world with increasing demands for food, energy, raw materials and goods, and at the same time confronted with a population explosion. Views the future of the United States optimistically when compared to less developed countries. (JR)

Summarizes the argument between the advocates of stream straightening for flood control, drainage, and navigation, and those concerned with the maintenance of ecological communities and the aesthetic values of natural" streams. (AL)

Describes the effects of one particular case of stream channelization. (AL)

Questions the feasibility of, and validity of the concepts behind, some of the new procedures proposed by the Water Resources Council. Concludes that the proposed procedures, if accepted in their present form, will bias water resource management in favor of development and against the preservation of the natural environment. (JR)

Analyzes several reasons for conservation of natural resources. Environmentalists and profit-making groups should decide together what needs preservation. Author points out that everything rare is not worth preservation. Priorities for preserving the environment are discussed. (PS)

Fuel cells have several advantages over conventional ways of producing power. A brief explanation of operating principles, structure, and economic considerations is presented. (PS)

Discussed in this editorial is the need for a broad and detailed government policy on energy use. Oil companies can not be given complete responsibility to demonstrate usage of different energy sources. The government should construct plants because energy is connected with national security. (PS)

The combined-cycle system is currently regarded as a useful procedure for producing electricity. This system can burn natural gas and oil distillates in addition to coal. In the future when natural gas stocks will be low, coal may become an important fuel for such systems. Considerable effort must be made for research on coal gasification and…

Article provides an account of alternatives for solving energy shortage problems in future years. A national policy is needed. More concerted effort should be made to develop technologies for conversion of energy from conventional and non-conventional resources so that energy is cheaper, available for use and without environmental hazards. (PS)

A case history of a power plant proposal for Cayuga Lake, New York, illustrates problems of discussion-making on the use of natural resources. Discusses the motives of special interest groups, and the roles of citizens and scientists. Proposes principles of resoruce management. (EB)
