例如，法国兰斯潮汐电站已经运转了50多年，每年发电约54万太瓦时。
For example, the Rance Tidal Power Station in France has been there for over 50 years, producing around 540, 000TWh of electricity each year.
根据国际可再生能源机构（IRENA）的数据，我们只需利用2%的海岸线，就能每年生产4383太瓦时的海洋电力，足以满足全世界4%的电力需求。
According to the IRENA (the International Renewable Energy Agency) , by just using 2% of our coastlines, we can produce 4,383 TWh of ocean power each year, enough to meet 4% of the world's electricity needs.
2005年结束的时候年均发电量是120太瓦时左右。
At the end of 2005 the average annual production capacity was about 120 TWh.
既便如此，对去年高达337.6太瓦时的总需求来说，这只是杯水车薪。
Even so, it will make only a small contribution to total demand, which last year amounted to 337.6TWh.
