新能源有核能、太阳能、风能、生物质能、地热能、潮汐能等许多种。新能源的共同特点是比较干净,除核裂变燃料外,几乎是永远用不完的。由于煤、石油、天然气等常规能源具有污染环境和不可再生的缺点,因此,人类越来越重视新能源的开发和利用。 New energy sources include nuclear energy, solar energy, wind energy, biomass energy, geothermal energy and tidal energy. The common feature of new energy is relatively clean, except for nuclear fission fuel, almost never use up. As conventional energy sources such as coal, petroleum and natural gas have the disadvantage of polluting the environment and being non-renewable, people pay more and more attention to the development and utilization of new energy sources.
