The Application of Solar energy Solar energy is radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies such as solar heating, photovoltaics, solar thermal energy, solar architecture and artificial photosynthesis. The Solar energy as a kind of natural energy, with abundant and nonpolluting, shows its unique advantages and has been internationally recognized as one of the most competitive energy future. The application of solar energy has huge impacts on society. The application of solar energy has a long history. Thousands of years ago in china, people used a concave mirror to convergent sunlight flame ignited moxa, which is a great progress in human history.
