On a conservative estimate, food-price rises may reduce the spending power of the urban poor and country people who buy their own food by 20% (in some regions, prices are rising by far more).
The resulting estimate for wind speed in a particular location can then be converted into an estimate of electricity generation using a power curve, based on the capabilities of specific turbines.
通过建立在特定涡轮机上的功率曲线，这种特定位置风速的预估结果，就可以被转化成电流产生量的评估值。

The most obvious method to estimatepower usage is to use CPU load as an indicator.
