While that sounds impressive, it depends on a massive 68% increase in the price of fossil-fuel-produced electricity by 2030. And Copenhagen is not alone in making such assumptions; the United Kingdom’s Department of Energy & Climate Change estimates a 51% price increase by 2030.
尽管听起来非常诱人，但这取决于到2030年化石燃料发电电价是否会大涨68%。并不只有哥本哈根做出这样的假设；英国能源与气候变化部预测到2030年化石燃料发电电价会出现51%的涨幅。
