海洋能源是海水本身所具有的自然能量,是一种可再生的能源,包括海水运动的动能(波浪能、潮汐能、海流和潮流能),海水的热能(温差能),海水的化学能(盐度差能)等。目前,海洋能源作为新能源和可再生能源的复合能源,受到人们的关注,越来越多的国家正把海洋能源的开发利用列为八十年代海洋开发的重要课题。为了开发利用海洋能源,许多专家学者对世界海洋能源的蕴藏量进行了估算。表1列出 Marine energy is the natural energy possessed by seawater itself. It is a kind of renewable energy, including the kinetic energy (wave energy, tidal energy, ocean current and tidal energy) of seawater movement, the thermal energy of seawater (temperature difference energy), the chemical energy of seawater Salinity difference energy) and so on. At present, as a composite energy source of new energy and renewable energy, marine energy has drawn people’s attention. More and more countries are making the development and utilization of marine energy an important issue in marine development in the 1980s. In order to develop and utilize marine energy, many experts and scholars have estimated the world’s marine energy reserves. Table 1 lists
