Presents in tabular form our energy choices including method, description, state of technology, difficulties, current capabilities, probable potential, relative cost, and availability. (GS)

The author describes a 1934 visit to the Berkeley radiation laboratory. The state of physics at that time and the life of persons doing basic physics research in radiation are discussed. (JP)

Proposes a method of collecting solar energy by using available plastics for Fresnel lenses to focus heat onto a converter where thermal dissociation of water would produce hydrogen. The hydrogen would be used as an efficient non-polluting fuel. Cost estimates are included. (AL)

Suggests a system for collecting and storing solar energy to be used as the heat source for conventional thermal powerstations. Considers the environmental and demographic impact of such systems in the desert areas of the southwest U. S. (AL)

The goals of solar photovoltaic technology in contributing to America's future energy needs are presented in this study conducted by the American Physical Society. Although the time needed for photovoltaics to become popular is several decades away, according to the author, short-range applications are given. (Author/SA)
