The International Energy Agency has even predicted that global energy use will increase by 30 percent over the next two and a half decades.

國際能源署預估全球能源用量於未來 25 年內將提高 30%。

With crude oil, the source of so much volatility around the world, there is no question that the future of energy will be based on countries dedicated to alternative, renewable sources.

天然能源在全球消耗速度極快，未來能源無庸置疑地將依賴國家投入研發替代的新興能源。

So, which countries are the most energy efficient?

那麼，哪些國家是最節能的呢？

Well, the American Council for an Energy-Efficient Economy has ranked the world's 16 largest economies, which account for nearly three-quarters of global electricity consumption.

美國節能經濟理事會（ACEEE）公布世界前 16 大經濟體這些經濟體用電量佔將近四分之三的全球用電量。

This is based on 31 metrics, spanning energy use in buildings, industry, and transportation.

這項排行榜主要考量 31 項標準，例如建築、工業、交通的用電情況。

It includes things like the country's national energy savings goals, vehicle fuel economy standards, and energy consumed per foot of floor space.

考察內容包含國家節能目標、交通工具能源經濟標準以及每層樓以面積計算的用電情況。

The United States ranks among the least efficient, at number thirteen.

美國居於排行榜尾端，是第 13 名。

But across the board, Germany saw the greatest energy efficiency, scoring well in all metrics, but especially industry.

但隔海的德國則是最節能的國家，在考察項目中屢獲佳績，尤其是工業。

According to the report, German industry and manufacturing is the second most fuel efficient in the world, with plans to far surpass the current leader, Australia, by 2020.

該報導指出，德國的工業與製造業是世界節能第二名，根據他們的計畫，很有可能在 2020 年超越當今節能第一名的澳洲。

Part of the reason Germany is doing so well is a national policy dedicated to lowering energy use known as Energy Transition.

德國表現優異有一部分原因是致力於降低能源用量的國家政策，稱為「能源轉型」。

The goal of this program is to stop using coal and other non-renewable energy sources like oil. Clearly, it's been working so far.

這項計畫的目標是停止使用煤炭和其他像是石油等不可再生能源。很顯然地，目前為止成效不錯。

In 2014, Germany accounted for half of the new wind farms in the EU, and has been leading the world in energy efficiency.

2014 年，德國擁有的風力發電裝置量佔歐盟一半，並居於世界節能領先地位。

In an extremely close second place overall, Italy actually surpasses Germany in transportation.

排名緊追在後的義大利其實在交通工具方面勝過德國。

Although they tie with the UK for vehicle fuel efficiency, at nearly 40 miles per gallon on average, Italians also travel the least per capita.

雖然在交通工具節能方面與英國不相上下，平均達1加侖行駛 40 英哩，然而義大利平均每人旅遊所消耗的能源是最低的。

This low impact, high efficiency makes Italy a world leader in transit energy.

這樣的低消耗高效能讓義大利成為能源轉型的龍頭。

Additionally, Italy tends to prioritize its rail system over its roads, leading to more people taking the train, and thereby saving considerable energy.

此外，義大利傾向鐵路優先於公路，因此搭火車的人越多，從而省下相當數量的能源。

Still, Italy continues to primarily use fossil fuels, and actually scores the worst in terms of commercial building energy efficiency.

不過，義大利仍大量使用化石燃料，事實上在商業建築節能方面分數最低。

When it comes to buildings, China takes the lead.

提到建築，中國則居於首位。

Their polluting past and wide range of energy inefficiency may hold them back,

他們過去的污染以及大量不節能的情況可能導致他們排名落後，

but China's residential buildings use less energy per square foot than any other country in the report.

但該報導指出中國的居家住宅每平方英尺使用的能源較其他國家低。

This is partially due to the fact that energy intensity is one of the country's top priorities.

雖然在交通工具節能方面與英國不相上下，平均達1加侖行駛40英哩（１加侖=3.785412公升；40英哩= 64.37376公里）

And despite being known for wastefulness, between 1980 and 2010, energy consumption increased five times, while the economy grew 18 times.

然而義大利平均每人旅遊所消耗的能源是最低的。這樣的低消耗高效能

Between Germany, Italy, and China, emerging countries can look at their journeys towards energy efficiency and fine-tune their own programs for maximum output.

讓義大利成為能源轉型的龍頭。此外，義大利傾向鐵路優先於公路

Still, every country surveyed has a long way to go, and plenty of areas to improve.

因此搭火車的人越多，從而省下相當數量的能源

Hopefully, 2016 will see even greater use of renewable and alternative energies.

不過，義大利仍大量使用化石燃料，事實上

But while the world's biggest economies are focusing on energy efficiency, other are battling energy poverty.

在商業建築節能方面分數最低

It's getting dark out and this facility has no power. Rachel is about to see a client who could give birth at any moment. So Rachel basically has to do whatever she can just to make it work.

每平方英尺使用的能源較其他國家低。這可能是因為
