摘要

直到20世纪中叶,人们都坚信下个世纪将是可再生能源和核能的时代。然而,目前,全世界都依赖化石燃料来满足他们的能源需求。环境污染和全球变暖是与使用化石燃料发电有关的主要问题。根据《2016年美国能源信息工业展望》报告,煤炭、天然气和石油占全球发电量的67.2%,而可再生能源仅占21.9%。这一份额仅占全球电力需求的五分之一。根据国际能源署2016年中期可再生能源市场报告,2014年全球海洋发电能力仅为539兆瓦,要达到640兆瓦的水平,需要2021年。海洋覆盖了地球表面积的70%,是最大的热能收集器。最近的一项研究表明,全球海洋能源的开发能力约为337吉瓦,这一潜力可产生超过885太瓦时的电力。

Ocean Energy
Until the middle of 20th century, there was a strong conviction that the next century would be the age of renewable and nuclear energy resources. However, at present, the whole world is dependent on fossil fuels to satisfy their energy need. Environmental pollution and global warming are the main issues associated with the use of fossil fuels for electricity generation. As per the report of US Energy Information IE Outlook 2016, coal, natural gas, and petroleum share nearly 67.2% of global electricity generation whereas renewable energy shares only 21.9%. This share is only one-fifth of the global electricity demand. According to the IEA 2016 Medium Term Renewable Energy Market Report, worldwide power production capacity of marine was only 539 MW in 2014, and to reach at a level of 640 MW, it will take 2021. The oceans cover about 70% of the Earth and acts as the largest thermal energy collector. A recent study reveals that global development capability of ocean energy is approximated to be 337 GW, and more than 885 TWH of electricity can be produced from this potential.
