据阿纳多卢新闻4月24日消息称，总部位于伦敦的智库Carbon Tracker上周五发布的一份新报告称，过去几年，太阳能和风能的成本大幅下降，开启了一种能源储备，以目前的技术，这些能源可以满足全球100倍的需求，而且与化石燃料相比，大多数能源已经很经济。
这份题为《天空的极限》的报告发现，自2010年以来，太阳能的成本每年平均下降18%，这极大地释放了太阳能的经济潜力。在这个规模下，太阳能的发展速度比以往任何一种能源技术都要快，在过去10年里，平均每年增长39%，每两年几乎增加一倍的产能。
风能的发展轨迹与此类似，在过去十年中，风能的产能每年增长17%。
以目前的技术，全世界每年仅从太阳能中就有可能捕获超过580万太瓦时的电力，而从陆地和海上风能中则有90万太瓦时的电力。
报告称，该国每年总发电潜力为6700万太瓦时，已经是2019年全球6.5万亿千瓦时能源消耗的100倍。
然而，全世界只使用了0.01%的太阳能和0.16%的风能。
-到2050年，化石电力将成为历史
报告称，随着成本下降推动效率和进步，如更好的电池板和更高的涡轮机，从而进一步降低成本，金融市场正在意识到这一机遇。
报告称，去年，清洁能源公司通过公开募股筹集的资金首次超过化石燃料公司。

Solar, wind can meet world energy demand 100 times over
Huge declines in the cost of solar and wind power over the last years unlocked an energy reserve that can meet world demand 100 times over with the current technology and most is already economic compared to fossil fuels, according to London-based think-tank Carbon Tracker's new report published Friday.
The report, entitled The Sky's the Limit, found that the solar power's economic potential has been unleashed by a dramatic drop in costs by an average of 18% every year since 2010. The solar power is growing faster than any previous energy technology at this size with an average annual rise of 39% in the last decade by nearly doubling capacity every 2 years.
Wind, following a similar trajectory, saw annually 17% capacity increase over the last decade.
The world has the potential to capture more than 5,8 million terawvatthours of electricity annually from solar alone while 900,000 teravathours from onshore and offshore wind with the current technology.
The total potential to generate 6,7 million terawatthours of electricity annually is already 100 times over the world's 65,000 terawatthours of energy consumption in 2019, the report said.
However, the world uses only 0.01% of the potential of solar and 0.16% of wind energy.
- Fossil electricity to be a thing of past by 2050
As the falling costs are driving efficiencies and advances such as better panels and higher turbines which reduce costs further, financial markets are waking up to the opportunity, said in the report.
Last year, clean energy companies raised more money through public offerings than fossil fuel companies for the first time, the report said.
