可再生能源消費(fèi)量正以驚人的速度增長

盡管全球主要能源消費(fèi)出現(xiàn)了自二戰(zhàn)以來的最大降幅，但2020年全球可再生能源消費(fèi)增長了9.7%

據(jù)油價(jià)網(wǎng)8月27日?qǐng)?bào)道，疫情大流行初期，世界能源消耗大幅下降。除了一種能源以外，所有主要能源生產(chǎn)都出現(xiàn)了下降。盡管全球主要能源消費(fèi)出現(xiàn)二戰(zhàn)以來最大降幅，但2020年全球可再生能源消費(fèi)增長9.7%。考慮到疫情對(duì)能源總需求的重大影響，這一數(shù)字令人矚目。

2021年，所有類別的能源趨勢(shì)都出現(xiàn)反彈。但可再生能源再次領(lǐng)先。從2020年到2021年，全球可再生能源消費(fèi)增長了15%。

過去十年來，全球可再生能源消費(fèi)以指數(shù)級(jí)增長，平均年增長率為12.6%。可再生能源是全球唯一在今年和過去十年以兩位數(shù)增長的能源。

2010年，全世界消耗了10.5艾焦耳的可再生能源。2021年，達(dá)到了39.9艾焦耳。2021年可再生能源消費(fèi)增長5.1艾焦耳，創(chuàng)下一年來的新高，創(chuàng)下可再生能源消費(fèi)歷史新高。

《評(píng)論》報(bào)告稱，水力發(fā)電作為一個(gè)單獨(dú)的類別，在全球范圍內(nèi)的增長速度遠(yuǎn)遠(yuǎn)低于太陽能等現(xiàn)代可再生能源。2021年全球水電消耗為40.3艾焦耳，但仍高于風(fēng)能和太陽能。然而，水電10年平均年增長率要低得多，只有1.5%。

2021，在全球范圍內(nèi)，水力發(fā)電占世界主要能源消耗的6.8%，略高于風(fēng)能和太陽能等現(xiàn)代可再生能源的6.7%。但現(xiàn)代可再生能源在今年的總消耗量將最終超過水力發(fā)電。

在可再生能源類別中，風(fēng)能（49.0%）和太陽能（27.2%）占了大部分的消費(fèi)。雖然風(fēng)能消耗保持著相對(duì)于太陽能消耗的健康領(lǐng)先，但十年來太陽能消耗的增長速度繼續(xù)是風(fēng)能增長速度的兩倍多。

累計(jì)來看，2021年前10大消費(fèi)國占全球可再生能源消費(fèi)量的75.9%。

但這是世界面臨的挑戰(zhàn)。在全球可再生能源消耗增加5.1艾焦耳的背景情況下，2021年全球能源需求增加了31.3艾焦耳——是原來的6倍多。根據(jù)目前的趨勢(shì)，可再生能源的增長需要10年以上才能趕上全球能源需求的增長。

Global Renewable Energy Consumption Is Soaring

●Renewable energy consumption is growing at a blistering rate.

●Despite the largest decline in primary global energy consumption since World War II, global renewable energy consumption grew by 9.7% in 2020.

During the early stages on the Covid-19 pandemic, the world’s energy consumption plunged. All major categories of energy production declined, except for one. Despite the largest decline in primary global energy consumption since World War II, global renewable energy consumption grew by 9.7% in 2020. That was remarkable given how significantly the pandemic impacted total energy demand.

Energy trends in all categories bounced back in 2021. But renewables once again led the pack. From 2020 to 2021, global renewable energy consumption grew by a whopping 15%.

Over the past decade, global renewable energy consumption has grown exponentially, at an average annual rate of 12.6%. Renewables were the only category of energy that grew globally at double digits over the year and the past decade.

For perspective, in 2010 the world consumed 10.5 exajoules of renewable energy. In 2021, that had reached 39.9 exajoules. The 5.1 exajoule increase in renewable consumption in 2021 was a record increase for one year, and it set a new all-time high for renewable energy consumption in a year.

Hydroelectricity, which the Review reports as a separate category is growing globally at a much slower rate than modern renewables like solar power. Global hydropower consumption in 2021 was 40.3 exajoules, which is still more than wind and solar. However, the 10-year average annual growth rate for hydropower is much lower at only 1.5%.

Globally, hydroelectricity represented 6.8% of the world’s primary energy consumption in 2021, just barely ahead of the 6.7% for modern renewables like wind and solar power. But modern renewables will finally overtake hydroelectricity in overall consumption this year.

Within the Renewable Power category, wind (49.0%) and solar (27.2%) accounted for most of the consumption. Although wind consumption maintains a healthy lead over solar consumption, the ten-year growth rate in solar power consumption continues to be more than double the growth rate of wind power.

Cumulatively, the Top 10 consumers accounted for 75.9% of the world’s renewable energy consumption in 2021.

But here is the challenge the world faces. Against the backdrop of the 5.1 exajoule global increase in renewable energy consumption, global energy demand increased by 31.3 exajoules in 2021 — over six times as much. based on the current trends it would take over a decade before renewable growth can match global energy demand growth.
