风能和太阳能正在破坏电力系统,但这并不是政府停止支持可再生能源的理由。在光伏电池和风力发电机发明近150年后,它们的发电量仍只占全球总量的7%,而现在正发生着一些翻天覆地的变化。十多年前他们还是次要的能源系统,但现在它们的增长速度超过其他任何能源,并且下降的成本也使得其竞争力能够与化石燃料相抗衡。石油公司BP预计,未来20年内可再生能源将占全球能源供应增长的一半。现在是时候认为世界正在进入一个清洁、廉价和电力无限供应的时
Wind and solar are damaging the power system, but this is not the reason the government stopped backing renewable energy sources. Nearly 150 years after the invention of photovoltaic cells and wind turbines, they still generate only about 7% of the world’s electricity, and some radical changes are taking place. They were still secondary energy systems more than a decade ago, but now they are growing faster than any other energy source and the declining cost makes it competitive with fossil fuels. BP, an oil company, predicts that renewable energy will account for half of the global energy supply growth in the next 20 years. Now is the time to think that the world is entering a clean, cheap and unlimited supply of electricity
