一种方法是海水蒸馏，通过加热卤水可以得到浓缩的水蒸气，这种方法每淡化1立方米的海水需要10千瓦时的电量。
Some employ distillation, which needs about 10 kilowatt-hours (kWh) of energy per cubic metre of seawater processed. Brine is heated, and the resulting water vapour is condensed.
当这一车型的16千瓦时的电池组用尽时，它会自动切换到燃气发动机——这一转换过程非常平滑(在行驶中几乎无法察觉)。
When the car's 16-kilowatt-hour battery pack becomes depleted, the car automatically switches to a gas engine-a transition that is remarkably smooth (it's nearly impossible to discern on the road).
但是健康饮食和电费单不同，这不仅仅是像减少千瓦时用电一样食用更少的盐或糖那么简单。
But a healthy diet isn't like an electricity bill; it's not as simple as using less salt or sugar as though you were cutting down on your kilowatt hours.
每千瓦时电能的生产都会排放一定量的 CO2。
The electricity production process will typically result in a certain amount of CO2 emission per KWH generated.

It's not as simple as using less salt or sugar as though you were cutting down on your kilowatt hours.
因为氢生产是一种能量密集型工序，从甲烷获取氢每千瓦时将产生更多的二氧化碳。
The production of hydrogen from methane in converters will generate higher CO2 emissions per kilowatt hour since [hydrogen production] is an energy-intensive process.
平均来说，一个普通四口之家每月用电量为800千瓦时，而大部分住宅屋顶太阳能电池板的发电量低于10千瓦。
A typical family of four people USES, on average, 800 Kwh per month and most residential rooftop units are of under 10kw capacity.
电度表电度表记录系统中某一点的总电力输出，通常以千瓦时为记录单位。
Watt-Hour Meter A watt-hour meter records the total power output at a specific point in a system. Typical recording increment is in kW-hours.
每个模块有自己独特的电子管理系统以优化其充电和放电速率。结果显示，该公司称，一个模块可以在短短30分钟内从没电状态到充满电，并能在短短六分钟内放完全部6.2千瓦时电能。
The result, says the company, is that a module can be charged from flat in as little as 30 minutes and is able to discharge its full 6.2 kilowatt-hours in just six minutes.
