目前，生活于地球这颗行星上的人数已超过60亿，到本世纪中期，大有达到百亿之势，维持人类日常生活、文化，需消费大量的能源。但过度的能源消耗在促进人类发展的同时，会使地球环境恶化，甚至成为威胁人类生存的因素。因此，为了今后人类的可持续发展，由传统的矿物燃料向太阳能、水能、风能之类的绿色可再生能源的转变是能源发展的必然趋势。At present, the number of people living on the planet earth has exceeded 6 billion, and by the middle of this century, it will reach 10 billion. To maintain human daily life and culture requires a large amount of energy consumption. However, while excessive energy consumption promotes human development, it will deteriorate the earth's environment and even become a factor that threatens human survival. Therefore, for the sustainable development of mankind in the future, the transformation from traditional fossil fuels to green renewable energy such as solar energy, water energy, and wind energy is an inevitable trend of energy development.
近年来，由于农村在养殖种植方面获得大力发展，随之产生的大量养殖种植的废料，该废料能够产生大量的沼气，采用沼气来发电，实现能源的循环利用，但是由于沼气发电因季节和时间的不同，产生沼气量会有所不同，不能够实现持续有效的利用，达到稳定的电能需求。同样的问题也出现在太阳能、风能和水能的利用上。In recent years, due to the vigorous development of farming and planting in rural areas, a large amount of farming and planting waste has been produced. The waste can generate a large amount of biogas, and use biogas to generate electricity to achieve energy recycling. The amount of biogas produced will be different, which cannot achieve continuous and effective utilization and stable power demand. The same problem also arises in the use of solar, wind and hydro energy.
