低碳能源变得非常便宜的情况,或许不太可能发生。乍看之下,现在的迹象似乎很有希望——丹麦、德国和葡萄牙都曾宣布在某个时点实现了全电网由可再生能源供电,但要宣告胜利还为时尚早。我们是否会停止使用化石能源呢?这个问题很重要,因为化石能源是气候变化的最大致成因素。尽管找到更好的办法来生产水泥、防止森林砍伐甚至减少牛羊肠胃胀气都不错,但我们大幅削减温室气体排放的唯一希望,是找到更清洁的发电方法 。
Low-carbon energy has become very cheap, and perhaps less likely to happen. At first glance, the signs now seem promising: Denmark, Germany and Portugal both announced at some point that the entire grid would be powered by renewable energy sources, but it is still too early to declare victory. Will we stop using fossil fuels? This issue is important because fossil fuels are the biggest contributor to climate change. Despite finding better ways to produce cement, prevent deforestation and even reduce flatulence in cattle and sheep, the only hope we can slash greenhouse gas emissions is to find cleaner ways of generating electricity.
