Today petroleum provides around 40% of the world's energy needs, mostly fuelling automobiles. Coal is still used, mostly in pover stations, to cover one-quarter of our energy needs, but it is the least efficient, unhealthiest and most environmentally damaging fossil fuel. Natural gas reserves could plug some of the gap from oil, but reserves of that will not last into the 22nd century either. Most experts predict we will exhaust easily accessible reserves within 50 years. We could fast reach an energy crisis. We need to rapidly develop sustainable solutions to fuel our future. Less-polluting renewable energy sources offer a more practical long-term energy solution. They may benefit the world’s poor too. “Renewable” refers to the fact that these resources are not used faster than they can be replaced.

Hydroelectric power is now the most common form of renewable energy, supplying around 20% of world electricity. China's three gorges Dam, which has just been completed, is the largest ever. At five times the size of the US’s Hoover Dam, its 26 turbines will generate the equivalent energy of 18 coal-fired power stations. It will satisfy 3% of China's entire electricity demand.

In 2003, the first commercial power station to harness tidal currents in the open sea opened in Norway. It is designed like windmill, but others take the form of turbines. 

As prices fall, wind power has become the fastest growing type of electricity generation – quadrupling worldwide between 1999 and 2005. Modern wind farms consist of turbines that generate electricity. Though it will be more expensive, there is more than enough wind to provide the world's entire energy needs. Wind farms come in onshore and offshore forms. They can often end up at spots of natural beauty, and are often unpopular with residents. And turbines are not totally benign – they can interfere with radar and leave a significant ecological footprint, altering climate and lilling sea birds. Migrating birds may have more luck avoiding them. Scotland is building europe’s largest wind farm, which wil power 200,000 homes. The UK's goal is to generate onefifth of power from renewable sources, mainly wind, by 2020. But this may cause problems, because wind is unreliable.

译文：

今天，石油公司提供了世界能源需求的40％左右，主要是加油汽车。仍然使用煤炭，主要是在摊铺站，以满足我们四分之一的能源需求，但它是化石燃料效率最低，不健康和最具环境破坏性的化石燃料。天然气储量可能堵塞石油的一些差距，但储量不会持续到二十二世纪。大多数专家预测，我们将在五十年内排除容易获取的储备。我们可以快速实现能源危机。我们需要快速开发可持续解决方案来推动我们的未来。污染较少的可再生能源提供更实际的长期能源解决方案。他们也可能惠及世界的穷人。 “可再生能源”是指这些资源的使用速度比可以更换的速度更快。 

水力发电现在是最常见的可再生能源，占世界电力的20％左右。中国刚刚完成的三峡大坝是有史以来最大的。美国胡佛水坝的五倍，其26台风机将产生18个燃煤发电站的能源。将满足中国全部电力需求的3％。 

2003年，在挪威开放的第一个开放海域潮汐潮的商业发电站开通。它被设计成风车，而其他则采用涡轮机的形式。 

随着价格的下降，风电已成为发展最快的发电类型，1999年至2005年间全球增长了四倍。现代风电场由发电的涡轮机组成。虽然这将是更昂贵的，但足够的风力来提供世界的整个能源需求。风电场进入陆上和海上形式。他们经常可以在自然之美的地方结束，往往不受居民的欢迎。涡轮机不是完全良性的-它们可以干扰雷达并留下重要的生态足迹，改变气候和养殖海鸟。迁徙鸟可能会有更多的运气避免他们。苏格兰正在建设欧洲最大的风力发电场，将为20万个家庭提供动力。英国的目标是到2020年，从可再生能源（主要是风力）产生一次电力。但这可能会导致问题，因为风是不可靠的。
