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

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。)

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.(每個飛輪能存儲15分鐘的100千瓦電量，而且能在20年間放電15萬次。)

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單不同，這不僅僅是像減少千瓦時用電一樣食用更少的鹽或糖那么簡單。)

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400千瓦的燃料電池，還計劃安裝更多的，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.(為一千瓦時電，就是四百萬焦耳，我只花區(qū)區(qū)10美分。)
