據彭博新聞社2023年1月29日報道，彭博新能源財經（BNEF）在其《2023年能源轉型投資趨勢》報告中表示，2022年全球對清潔能源轉型的投資達到1.1萬億美元，大致相當于對化石燃料生產的投資。2022年以前用于轉向可再生電力、電動汽車和氫氣等新能源的支出從未超過1萬億美元。

雖然這一數字比2021年增長了31%，但仍然只是削減溫室氣體排放和應對全球變暖所需的投資的一小部分。BNEF估計，在本十年的剩余時間里，每年在轉型方面的投資必須增加兩倍，才能讓世界有機會在2050年前實現凈零排放。

太陽能發電和風力發電在2022年的綠色投資中占比最大，達到4950億美元，比前一年增長17%。電動汽車投資緊隨其后，投資金額為4660億美元，而且全球電動汽車投資的增長速度要快得多，達到54%。全球能源轉型投資的近一半(5460億美元)在全球能源消費最大國，而美國以1410億美元位居第二。如果歐盟作為一個單一實體計算，歐盟將以1800億美元的投資排名第二。

據BNEF稱，這1.1萬億美元的綠色投資包括投資部署清潔能源技術的資金。這還不包括去年全球用于擴大和加強電網的2740億美元，投資清潔能源供應鏈和制造業的790億美元，以及清潔技術公司籌集的1190億美元股權融資。加在一起，用于轉型的綠色投資總額將上升到約1.6萬億美元。

清潔能源投資基本上與化石燃料投資掛鉤，這一點值得注意，因為在2022年，對老舊、污染能源的投資有所上升。根據BNEF公布的數據，在高油價的推動下，全球對該行業的投資大幅攀升了2140億美元。

$1 Trillion Green Investment Matches Fossil Fuels For First Time

Global investments in the clean energy transition hit $1.1 trillion in 2022, roughly equal to the amount invested in fossil fuel production, the research firm said in its “Energy Transition Investment Trends 2023” report. Never before has the amount spent on switching to renewable power, electric cars and new energy sources like hydrogen topped $1 trillion.

While the amount represents a 31% jump from 2021, it’s still just a fraction of what’s needed to slash greenhouse gas emissions and fight global warming. BNEF estimates annual investments in the transition must triple for the rest of this decade to give the world a shot at reaching net-zero emissions by 2050.

Solar and wind power accounted for the biggest chunk of 2022 investments, reaching $495 billion, a 17% increase from the previous year. But electric vehicles came in close behind, with $466 billion, and the amount invested in them worldwide is growing far faster, at 54%. Nearly half of all global energy transition investments — $546 billion — were in the global larggest consumer, while the US came in second at $141 billion. (Had BNEF counted the European Union as a single entity, it would have ranked second, with $180 billion.)

The $1.1 trillion covers money invested in deploying clean-energy technologies, according to BNEF. It does not include $274 billion spent worldwide last year on expanding and strengthening power grids, $79 billion invested in clean-energy supply chains and manufacturing or $119 billion in equity financing raised by clean-tech companies. Added together, the amount invested in the transition rises to about $1.6 trillion.

That clean power investments essentially tied those in fossil fuels is notable considering investments in those older, polluting energy sources rose in 2022. Driven by high fuel prices, worldwide investment in the sector climbed a substantial $214 billion, according to BNEF.
