Annual energy output

By 1830, Mr Ridley estimates, Britain was consuming coal with an annual energy output equivalent to 15m acres of forest, about three times the size of Wales.

里德利估计，至1830年止，英国每年消耗的煤炭能源总量相当于1500万英亩的森林，相当于威尔士的三倍大小。

Targets include increasing the renewable share of energy output to 20% by 2020, and ensuring that 10% of annual greenhouse gas emissions are "sequestered by forests" before 2030.

这些目标包括，可再生能源产量占总能源的份额将在2020年增至20%；在2030年前，确保每年10%的温室气体排放“被森林吸收”。

Beginning this year, the energy consumption per unit of output for all regions and major industries will be made public on an annual basis.

从今年开始，每年都要公布各地区和主要行业的单位产值能源消耗情况。
