Electric Cars Are Cleaner Even When Powered by Coal

Electric cars are better for the environment than traditional gasoline
models, and that benefit will grow as power generators shift away from coal.

電動車比起傳統燃油車對於環境更為友善，而且隨著發電廠逐漸擺脫燃煤，益處
會更大。

That’s the conclusion of research by BloombergNEF, which found carbon
dioxide emissions from battery-powered vehicles were about 40 percent lower
than for internal combustion engines last year. The difference was biggest in
Britain and the U.K., which have large renewables industries. It still held
in China, which is more reliant on coal to make electricity.

以上這是BNEF(彭博社新能源財經) 研究的結論，這項研究顯示去年電動車的CO2
排放量比起燃油車要低了約40%。在擁有大量再生能源的大不列顛(Britain) 與
英國(U.K.) 差異最大。這種狀況同樣發生在更依賴燃煤發電的中國。

The report adds clarity to the debate about the lifetime emissions of
electric vehicles, which while they don’t pollute on the road do consume
electricity that is often generated using fossil fuels. BNEF’s research
assumes that electric cars will become cleaner in the coming years as
utilities close coal plants and draw more energy from wind and solar farms, a
process well underway almost everywhere except Southeast Asia.

儘管電動車不會在道路上排放廢氣，但會消耗通常由化石燃料所產生的電力，而
這報告使得有關於電動車生命週期內排放的此種論戰更加清晰。BNEF 的研究推測
電動車未來數年會變得越來越清潔，因為公營事業正在關閉燃煤電廠並從風能與
太陽能中取得更多能源，除了在東南亞之外，幾乎所有地方都在進行中。

“When an internal combustion vehicle rolls off the line its emissions per km
are set, but for an EV they keep falling every year as the grid gets cleaner,
” Colin McKerracher, a transport analyst at BNEF said.

BNEF 的分析師Colin McKerracher 表示，"當燃油車下了產線後，每公里的排放
量就是那樣不會變了，但對電動車而言，隨著電網變的更加清潔，他們的排放量
每年都在下降中。

The chart above shows BNEF’s forecasts for how much the gap will grow, with
China expected to make rapid progress as its renewables industry takes a
bigger share of the power generation market in the coming years.

上圖顯示了BNEF 對於燃油車與各國電動車排放差距將會擴大多少的預測，隨著
中國可再生能源將在當地電力市場中佔據更大的比例，中國有望在此面向有快速
的發展。

The widespread adoption of renewables will decrease average emissions by as
much as 90 percent in the U.K. and over a third in Japan out to 2040,
according to BNEF.

根據BNEF 的說法，到了2040年，可再生能源的廣泛採用將使英國的平均排放量
減少多達90%、日本的平均排放量減少三分之一以上。

The global share of zero-carbon electricity generation is set to increase
from 38 percent last year to 63 percent by 2040, according to projections
from BNEF. While technological improvements will see related emissions from
combustion engines falling by about 1.9 percent a year through to 2040,
pollution from electric vehicles will fall anywhere from 3 percent and 10
percent annually. That’s largely because of grid decarbonization but also
reduced electricity consumption, BNEF says.

根據BNEF 的預測，到了2040年，無碳發電的比例將從去年的38% 上升至63%。而
技術進步可使內燃機的相關排放每年減少1.9%，但電動車的汙染每年將會下降
3 ~ 10%。這主要是因為電網逐漸擺脫化石燃料，但也是因為技術發展減少了電
動車的電力消耗。
