Energy intensity is closely linked to reducing greenhouse gases because most of China's power comes from burning fossil fuels, like coal, which release carbon.

因为中国大部分电力来源于燃烧煤等会导致碳排放的矿物燃料，因此能源强度与减少温室气体排放量密切相关。

Reducing emissions has become a fiercely-contested issue because ofthe cost of easing use of oil, gas and coal, the cheap and abundantfossil fuels that meet most of the world's energy needs.

由于减少使用石油、天然气和煤这些廉价丰富的化石燃料，以满足世界能源需求的成本可观，减排已成了激烈争议的问题。

By reducing energy intensity alone, China can save 620 million tons of standard coal in the five-year period, equivalent to cutting 1.5 billion tons of carbon dioxide emissions.

仅通过降低能耗一项，中国5年内可以节省能源6 . 2亿吨标准煤，相当于少排放15亿吨二氧化碳。

Due to costs associated with reducing sulfur emissions resulting from stricter pollution regulations, subbituminous coal is actually more economical for energy generation.
