他表示，只有当电价高于1.3至1.5元每千瓦时，才有可能盈利。
而排放硫、汞和煤灰的煤炭，其每千瓦时产能所造成的死亡人数仍将远远高于核能。
Coal, with its emissions of sulphur, mercury and soot, will continue to kill far more people per kilowatt hour than nuclear does.
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.
在之后的5年内每年攀升500亿瓦并帮助企业优化生产线，这样太阳能发电的价格将下降到6美分每千瓦时。
In the next five years, annual construction would rise to 5 GW apiece, helping firms optimize production lines. As a result, solar electricity would fall toward six cents per kWh.
据传，雷诺-尼桑已经将每千瓦时成本控制在400美元以下，因此，如果能继续按此趋势，他们的汽车将会有更大的竞争力。
According to industry rumours, Renault-Nissan has got its costs down to below $400 per kwh, so if it can continue this progress its cars will become much more competitive.
得益于性能更佳的涡轮和更大的发电量，自1990年以来，风力发电每千瓦时的成本从8 - 10美分下降下3.5 -4美分。
The cost of wind-power generation has come down from 8-10 cents to 3.5-4 cents per kWh since 1990 because of better turbines and higher volumes.
而中国的太阳能发电价格，在不考虑土地成本的情况下已降到了每千瓦时1元以下，其中光伏发电的价格已经降到0.73元。
While China's solar power price, in not consider land costs have fallen to every KWH 1 yuan, of which (pv) power prices have fallen to 0.73 yuan.
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。
