Wind energy is now competitive with conventional power plants, while rising gas and coal prices and the steady decline in renewable-energy costs imply that, within a few years, fossil fuels will be even less attractive. Moreover, revenues from “home-grown” energy tend to remain where they are generated, while the import bill for fossil fuels would be eliminated.
过去10年的应用已经表明，可再生能源产量增长反而会滩低它的成本。风能现在已经可以和传统电厂发电一较高下，而燃气煤炭价格攀升及可再生能源成本不断下降意味着在若干年内，化石燃料的吸引力将会进一步减弱。此外，“土生土长”的能源收入更能造福本地经济，而化石燃料的进口法案将被逐步取消。
