ABSTRACT
Energy is a critical foundation for economic growth and social progress. As economy advances and human society requires more energy, the lack of fossil energy and its pollution on the environment has given rise to the ever-serious contradiction among energy providing, environment protection and economic development. Renewable energy, with the availability of its renewability and non-pollution, will grow to be an effective and practical choice to guarantee the future development of the world. Currently, China’s solar energy is mainly intended for urban and rural domestic energy use and the power supply for remote areas. The solar water heater, passive sunshine house, solar furnace and photovoltaic cell all experience various levels of development. The employment of biomass energy in China includes biological chemical transition, the biomass gasification, biomass liquefaction and direct burning.
