Assuming complete success for the UK’s scheme, offshore wind power could produce more than 10% of the country’s electricity in 2020 and reduce its CO2 emissions by up to 22Mt, or 5%, per year. But the cost would also be phenomenal.
如果英国的安排获得十足的成功，那么离岸风能可以在2020年产出该国电力总量的10%，降低二氧化碳排放量22百万吨或5%。但成本也颇为壮观。英国每年至少得付出80亿美元用于补贴这一效率先天不足的技术。
