为缓解能源供应紧张的矛盾 ,各国科学家都在努力研究 ,积极寻找新能源。本世纪 ,波能、可燃冰、煤成气、微生物、绿藻将成为人类广泛应用的新能源。波能　即海洋波浪能。这是一种取之不尽、用之不竭的无污染再生能源。据科学家推测 ,地球上海洋波浪蕴藏的电能高达 90万亿千瓦。 To alleviate the contradiction between the tight supply of energy, scientists from all over the world are trying their best to find new sources of energy. This century, wave energy, combustible ice, coal gas, microorganisms, green algae will become a widely used new energy sources. Wave energy is the ocean wave energy. This is an inexhaustible source of non-polluting renewable energy. According to scientists speculation, the earth’s ocean waves contain up to 90 trillion kilowatts of energy.
