    energy comes to us from the sun in two main forms: heat and light. solar thermal technologies use water or air to trap the sun's heat. on a small scale, this kind of solar power is already being used to heat homes, offices, and factories. on a large scale, it could be used to drive huge electricity-generating power plants.
    太阳产生‘热能’和‘光能’两大能源。太阳热能技术运用水或空气来捕捉太阳的热能。在小规模应用上,这种太阳能目前已经用于为居室、办公室以及工厂供暖;在大规模应用上,这种太阳能可用于为大型发电厂提供电力。
