目前,人们获得的绝大多数能源是矿物燃料,如煤、石油等。70年代初的石油危机,已使人们意识到能源重要性。而石油、煤这些自然资源是有限的,随着不断的开采将日益减少,而且燃烧利用这些能源会造成环境污染,使温室效应、环境污染日趋严重。当今世界节约能源,保护环境的呼声越来越高,运用自然可再生能源的需求也逐步增加,太阳能是一种无污染,取之不尽,用之不竭的环保能源。我们可通过高科技手段将太阳能转变为电能,并加以高效利
At present, most of the energy people get is fossil fuels, such as coal, oil and so on. The oil crisis of the early 1970s has made people aware of the importance of energy. However, the natural resources such as oil and coal are limited, and their production will decrease with continuous exploitation. Combustion and utilization of these energies will cause environmental pollution and make the greenhouse effect and environmental pollution worsen. In today’s world, the voice of saving energy and protecting the environment is getting louder and louder, and the demand for using natural renewable energy is also gradually increasing. Solar energy is an inexhaustible and environmentally friendly energy source that is pollution-free and inexhaustible. We can convert solar energy into electricity by high-tech means and make it more efficient and cost-effective
