作者简介

The sun is the one energy source that　sustains and links all life.     Ancient societies paid homage to the sun as　a symbol of truth, justice and equality, as thefountainhead of wisdom, compassion and　enlightenment, as the healer of physical and　spiritual maladies, and, above all, as the source　of fertility, growth, renewal and peace with nature.     Solar energy takes many different forms. The　heat of the atmosphere, derived from absorbed solar　energy, powers the winds and the cycle of　evaporation and precipitation. Wind energy can be　harnessed with turbines, just as running water from　rain and melting snow is the energy source for　hydroelectric power. The wind blowing across　oceans and lakes transfers some of its energy to the　water below to form waves which, like the tides,may generate power.     The energy in biomass is derived from plants　and photosynthetic micro-organisms, which use the　energy of sunlight to synthesize organic compounds　whose chemical energy is released when they are　burned. Even the energy in fossil fuels is actually　solar energy that was first stored as Chemical energy　in biomass and then transformed into coal, oil or　gas over millions of years.     Today renewable solar energy is recognized by　many populations as being in harmony with their　cultural traditions because of its peaceful and　environmentally friendly associations. By reuniting　science and culture, and by making effective use of　what might be termed "the ultural tools of solar　technology", sustainable solar energy seems poised　to become the principal nergy of the future. The　efficient and economical use of solar energy derived　from the biomass, from wind and ocean power,from small hydroelectric facilities, from thermal,geothermal sources, and from photovoltaic and non　 nuclear hydrogen energy may well enable the　world to satisfy most of its energy requirements.
