在一年中，平均每个家庭耗费的燃气大约为2万个字(千瓦小时)。

In a year, the average home USES about 20, 000 units (kilowatt hours) of energy via gas use.

这种速度突增的动力来自一组电池，该电池组储有42千瓦小时的电能。

The power for these bursts of speed comes from a battery packet with a storage capacity of 42 kilowatt hours.

该计划为参加者提供太阳能电力的55至65美分每千瓦小时的设置率。

The program offers participants a set rate of between 55 and 65 cents a kilowatt hour for solar electricity.

最新估计表明，贫困户每天最初用电量为5小时内30-200瓦（W），相当于每年55-360千瓦小时（kWh）。

Recent estimates indicate that poor households, once electrified, would initially consume about 30-200 W during 5 hours per day, corresponding to 55–360 kWh per year.
