Energy: Planning solar´s future: Solar power struggles for economic viability; its proponents see it as an important, if small, complement to traditional sources

Examines the budgetary and developmental targets of various solar-electric technologies-namely, wind, photovoltaic, solar-thermal, ocean-thermal, and satellite power generation-in comparison with other technologies that are expected to contribute significantly, in the long term, to the generation of electric power. The present status and problems of some of the solar-electric technologies are also addressed.
