彭博商业周刊:如果全世界都能够使用页岩气,我们的清洁天然气供应量能够增加百分之四十七,既降低温室气体排放,也可降低能源价格.
清洁能源来之不易
If all the world's theoretically recoverable shale 1 gas could be developed, our supply of clean-burning natural gas would expand 47 percent—lowering both greenhouse gas emissions 2 and energy prices.
Bloomberg Businessweek says the hitch 3 is that the process for extracting shale gas, called hydraulic 4 fracking, sucks up as much as 25 million liters of water for each well.
A report from the Washington-based World Resources Institute shows that roughly 38 percent of the world's shale gas and oil lies buried beneath water-stressed regions. This means that extraction efforts will be difficult and expensive, as well as economically and environmentally risky 5.
The situation is especially true in China.
