Thirsty Clean Energy May Add to Water Stressed World, Newscientist, July 19th, 2013
對(duì)清潔能源的需求可能會(huì)給水資源增加壓力，新科學(xué)家科技雜志，2013年7月19日
As the world gets hotter and drier thanks to our predilection for burning fossil fuels.
由于我們對(duì)燃燒化石燃料的偏愛，世界變得越來(lái)越炎熱，越來(lái)越干燥。
The choices we make balancing power and water are already becoming an urgent issue in the fight against climate change, says Amanda Fencl of the Stockholm Environment Institute.
斯德哥爾摩環(huán)境研究所的阿曼達(dá)·芬斯?fàn)栒f(shuō)，我們保證水電平衡的這一選擇在應(yīng)對(duì)氣候變化的角度上已經(jīng)成為了一個(gè)緊迫的問(wèn)題。
While cutting emissions is necessary to curb global warming, some renewable and clean energy sources use more water than fossil fuel-powered plants,
美國(guó)能源部發(fā)布的一份報(bào)告指出，雖然削減溫室氣體排放是遏制全球變暖所必備的條件，但一些可再生能源和清潔能源比化石燃料發(fā)電廠需要更多的水資源。
finds a report released by the US Department of Energy - DoE) that looked at how resilient the US's power infrastructure is to climate change.
這份報(bào)告對(duì)美國(guó)電力基礎(chǔ)設(shè)施是否能面臨氣候變化的考驗(yàn)進(jìn)行了探討。
The biggest users of water in the US are power plants, particularly the fossil fuel and nuclear plants that together generate almost 90 per cent of the nation's energy.
在美國(guó)，水資源使用大戶是發(fā)電廠，尤其是化石燃料發(fā)電廠和核電廠為美國(guó)創(chuàng)造了90%的能源。
Nearly half the water the US consumes is used to cool these plants and drive their turbines. But some renewable and clean energy sources also need a lot of water, says the DoE report.
美國(guó)所消耗的水資源中，有將近一半的水資源是用于冷卻這些發(fā)電設(shè)備和驅(qū)動(dòng)渦輪機(jī)的。但是，美國(guó)能源部的報(bào)告指出，一些可再生能源和清潔能源也需要大量的水資源。
The main consumer is hydropower, which requires large reservoirs of water to generate electricity.
消耗的主力軍是水力發(fā)電，這就需要儲(chǔ)蓄大量的水來(lái)發(fā)電。
Other technologies use it indirectly, to irrigate biofuel crops, for example, or cool and wash solar panels.
其他的技術(shù)可以使用水資源來(lái)灌溉生物燃料作物，例如冷卻和清洗太陽(yáng)能電池板。
Currently renewable and clean energy technologies only make up a small proportion of the US's energy mix-for example, hydroelectric provides 7 per cent of the county's power,
目前，可再生能源和清潔能源僅僅占據(jù)了美國(guó)能源結(jié)構(gòu)的一小部分，例如，水力發(fā)電提供了7%的國(guó)家能源，
and solar less than 1 per cent-but if the US is going to meet its target of reducing carbon emissions by 80 per cent by 2050, renewables and clean energy will need to feature more heavily in future.Thank you.
而太陽(yáng)能提供的能源不超過(guò)1%，但如果美國(guó)要滿足到2050年，碳排放量減少80%的目標(biāo)，可再生能源和清潔能源需要在未來(lái)發(fā)揮更大的作用。謝謝。
