Energy: the solar prospect

Book ·
OSTI ID:7218953
About one-fifth of all energy used around the world now comes from solar resources--wind power; water power; biomass; and direct sunlight. According to Mr. Hayes, such renewable energy sources could provide 40 percent of the global energy budget by the year 2000; by 2025, humanity could obtain 75 percent of its energy from solar resources. Such a transition would not be cheap, but Mr. Hayes feels that if this timetable is not met, it will be because of political obstacles, since technology has already been proven for all the options. Transitions must take place, he says, with oil-based societies, foundations anchored in the Middle East and the price of oil out of reach of Third World countries. He then surveys briefly the other energy sources and cites their finiteness, environmental impacts, pointing out especially the hurdles that fusion must cross before the year 2025. Discussed in depth are solar heating and cooling, electricity from the Sun, utilizing the wind and falling water, power from biomass, heat storage in rocks or water, the hydrogen economy, pumped-hydro storage. Finally, energy conservation measures are pointed out and energy-use transitions needed in our buildings environment, transportation systems, and food consumption patterns are discussed, along with decentralized power systems for bridging the gap as we are weaned off oil and natural gas.
