人类目前开发利用的主要能源为化石能源,包括石油、天然气和煤炭三种。随着我国经济的迅猛发展和人民生活水平的不断提高,化石能源的消费快速攀升,能源短缺已成为中国经济发展的瓶颈。而且随着石油、天然气和煤炭的大量使用,造成严重的环境污染,威胁着城市化进展和人民健康。生物能源是通过绿色植物、藻类和光合细菌的光合作用,捕获太阳能,经代谢转换,贮存于生物质中的能量,是太阳能的有机贮存,是可再生能源的重要组成部分。
The main energy sources currently used for human development are fossil fuels, including petroleum, natural gas and coal. With the rapid economic development in our country and the continuous improvement of people’s living standards, the consumption of fossil fuels has rapidly risen. The energy shortage has become the bottleneck of China’s economic development. And with the heavy use of oil, natural gas and coal, it causes serious environmental pollution and threatens the progress of urbanization and people’s health. Bioenergy is the energy storage of solar energy through the photosynthesis of green plants, algae and photosynthetic bacteria. It is the organic storage of solar energy and an important part of renewable energy.
