Public Underestimates Savings of Energy Efficiency

Most of us know we should rein in our energy use. But to be successful, it’d help if we knew the best way to do it. So scientists asked more than 500 people, “What’s the most effective thing you can do to conserve energy?” The results were illuminating.

很多人都知道應(yīng)該嚴(yán)格控制能源消耗，而掌握最佳的管控方法則能幫助我們成功做到這一點(diǎn)。為此科學(xué)家們?cè)儐?wèn)了500多人：“你認(rèn)為最有效的節(jié)能方式是什么？”結(jié)果非常具有啟發(fā)性。

More than half the participants focused on conservation by curtailment: switching off the lights, changing thermostat settings and driving less. Only 12 percent went for efficiency: using compact fluorescent bulbs, insulating the house or driving a hybrid car. But scientists say that it’s actually these moves that yield the bigger energy savings. The results appear in the Proceedings of the National Academy of Sciences.

超過(guò)半數(shù)的受訪者認(rèn)為減少使用是節(jié)能重點(diǎn)——例如關(guān)燈、調(diào)節(jié)溫度器設(shè)置以及少開(kāi)車(chē)。僅有百分之十二的受訪者關(guān)注到能效問(wèn)題——例如使用節(jié)能燈泡、房子隔溫以及駕駛混合動(dòng)力汽車(chē)。但科學(xué)家表示，實(shí)際上后者能節(jié)省更多的能源。這項(xiàng)研究成果已在《美國(guó)科學(xué)院學(xué)報(bào)》上刊登了出來(lái)。

The study authors think that a big factor is that curtailment is easier to imagine doing—while efforts to improve efficiency would involve, for example, doing research about new appliances or cars, and spending money up front to buy them.

研究報(bào)告的作者認(rèn)為，問(wèn)題的關(guān)鍵在于人們更容易想到減少使用能源，而提高能效則涉及到研發(fā)新電器和新汽車(chē)等行為，而且購(gòu)買(mǎi)這些新產(chǎn)品還得先花錢(qián)。

But if people knew more about the actual energy requirements of their activities versus the savings available through efficiency, they might be spurred to act. To quote physicist and energy expert Arthur Rosenfeld: “Energy efficiency is like a Saudi Arabia under our cities.”

但假如人們進(jìn)一步了解他們?nèi)粘；顒?dòng)的實(shí)際能耗，以及通過(guò)提高效率能節(jié)省的能源的話,，他們就會(huì)迫不及待行動(dòng)起來(lái)了。引用物理學(xué)家和能源學(xué)家阿瑟·羅森菲爾德的一句話：“能源效率就好似藏在我們腳下的一個(gè)沙特阿拉伯。”
