In a word, yes. The price of solar energy has been dropping steadily for 30 years – by about 50% every decade – and we could likely accelerate that decline further with sufficiently large investments in research and development.
那么我们究竟能不能在未来20至40年间实现这一科技奇迹呢？总而言之，可以！太阳能的价格将在未来30年内稳步下降——大概每10年下降50%——而如果有足够大量的资金投入研究的话，我们可以进一步加快下降的速度。
