The power for these bursts of speed comes from a battery packet with a storage capacity of 42 kilowatt hours.(這種速度突增的動(dòng)力來(lái)自一組電池，該電池組儲(chǔ)有42千瓦小時(shí)的電能。)

Instead of needing 6.7 kilowatt-hours to produce 100 pounds of ice, the new machine will use 3.58 kilowatt-hours.(用6.7度電生產(chǎn)100磅冰（約45公斤）的事情即將成為歷史，新的機(jī)器做到同樣的事僅僅需要3.8度電。)

Electrical production more than doubled to 621 million kilowatt hours.(電力生產(chǎn)增加了一倍多，達(dá)到6.21億千瓦小時(shí)。)

The amount per kilowatt varies by state, so be sure to talk to your local utility about the details.(每一千瓦的電在不同地區(qū)的數(shù)目是不一樣的，所以，必須保證事先和你當(dāng)?shù)氐牟块T談好具體細(xì)節(jié)。)

Each flywheel can store a 15-minute, 100-kilowatt charge and can discharge 150, 000 times over 20 years.(每個(gè)飛輪能存儲(chǔ)15分鐘的100千瓦電量，而且能在20年間放電15萬(wàn)次。)

It's not as simple as using less salt or sugar as though you were cutting down on your kilowatt hours.(但是健康飲食和電費(fèi)單不同，這不僅僅是像減少千瓦時(shí)用電一樣食用更少的鹽或糖那么簡(jiǎn)單。)

The 9.2 kilowatt photovoltaic panels on the roof also provide energy for the home.(千瓦光伏的屋頂太陽(yáng)能板也為住宅提供能源。)

“But then the kettle drum comes in,” demanding a sudden power surge of 1-kilowatt.(但隨著引入定音鼓，需要1千瓦的電涌。)

Whole Foods has since installed two 400-kilowatt fuel cells and plans more, but not everywhere.(WholeFoods之后又安裝了兩臺(tái)400千瓦的燃料電池，還計(jì)劃安裝更多的，但不是所有的商店都要安裝。)

For one kilowatt-hour of electricity, which is four million joules, I pay only a lousy ten cents.(為一千瓦時(shí)電，就是四百萬(wàn)焦耳，我只花區(qū)區(qū)10美分。)
