介绍： 一个国家可以靠可再生能源独自生存吗？

 国际能源机构称，世界正处于第一次全球能源危机之中。自 2020 年夏天以来，天然气价格几乎上涨了五倍，而主要原因是俄罗斯入侵乌克兰。莫斯科切断了对反对战争的欧洲国家的天然气供应，导致各地的批发价格飙升。

许多国家转而使用煤炭作为发电站的燃料，这也导致煤炭价格在去年上涨了两倍。但是，煤炭不仅价格昂贵，而且是污染最严重的化石燃料。这种情况加速了对可再生能源的推动，但它们能否提供一个国家所需的全部电力--以及提供能源安全呢？

Can a country live on renewable energy alone?

 The International Energy Agency says that the world is in the middle of the first global energy crisis. The price of natural gas has increased almost five-fold since the summer of 2020, and the main cause is Russia’s invasion of Ukraine. Moscow has cut supplies of gas to European countries that oppose the war, causing the wholesale price to shoot up everywhere.

Many countries have turned to coal to fuel their power stations, also causing prices to triple in the last year. But as well as being expensive, coal is also the most polluting fossil fuel. The situation has accelerated the push towards renewables, but can they provide the all the power needed by a country – as well as providing energy security? So this week on the Inquiry, we ask: can a country live on renewable energy alone?
