日本是化石能源资源极为贫乏的国家，2011年“3.11”大地震引发的严重核泄漏事故，又导致绝大多数的核电站目前处于停堆状态。日本的能源供应正面临前所未有的压力，可以说进一步开发利用可再生能源成为日本21世纪应对能源问题的“终极”手段。通过对日本政府和产业界在光伏电池、海流发电、超导、热泵等四大新能源技术领域的投入进行重点考察，全面分析日本上述四大新能源技术的发展现状、技术流派和应用前景，以期为同样面临能源与环境两大问题的我国相关部门提供有益参考。%Japan is an island country extremely lacking in fossil fuel resources. The large“3.11”Earthquake in 2011 triggered a serious nuclear accident, for which the most nuclear power plants were shutdown even now. Japan’s energy supply is facing unprecedented pressure, so further developing the renewable energy has become“ultimate”means to deal with energy issues for Japan in the 21st century. This paper focuses on the efforts of the Japanese government and industry in the ifeld of four new energy technologies including solar power, ocean current power generation, superconducting, heat pumps, and analyzes the development status, technical category and application prospects of four new energy technologies, hoping to provide useful information for China’s relevant departments in the process of resolving energy and environment problems.
