可再生能源消耗在10年内增加两倍
原标题:可再生能源消耗在10年内增加两倍
中国石化新闻网讯 据俄罗斯油气网8月30日消息称,可再生能源是2020年与全球能源消耗下降趋势相反的一类。
尽管全球主要能源消费下降了4.5%——这是二战以来的最大降幅,但2020年全球可再生能源消费增长了9.7%。这与前一年的12.2%的速度相比略有下降,但考虑到疫情对能源总需求的严重影响,这是值得非常了不起的。
可再生能源是过去十年全球唯一以两位数增长的能源类别。相比之下,2010年,全球可再生能源消耗量为9.6艾焦。到2020年,这个数字增加了两倍,达到31.7艾焦。
上述可再生能源类别包括风能、太阳能、生物燃料、地热能和生物质能发电。英国石油公司的报告进一步将可再生能源消费细分为电力生产(即不含生物燃料),占所有可再生能源消费的88%。
在可再生能源类别中,风能(50.6%)和太阳能(27.2%)占了大部分消费。尽管风能的消费量保持着相对于太阳能消费量的健康领先地位,但太阳能消费量的增长速度几乎是风能的两倍,并有可能在本十年取代风能成为可再生能源的主要来源。
尽管可再生能源的增长速度迅猛,但重要的是要记住,全球能源消费总量正在增长。尽管全球可再生能源消耗在过去十年中增加了约 21 艾焦,但总体能源消耗却增加了 51 艾焦。
化石燃料消耗的增加是这一增长的主要组成部分,在过去十年中,每种化石燃料的消耗都有所增加(尽管煤炭的增长接近于零)。
因此,虽然可再生能源有助于减少二氧化碳排放的增长,但全球碳排放由于化石燃料消费的总体增长率而增长。
然而,由于2020年总体能源消费的下降,可再生能源消费的增长确实快于总体能源消费。反过来,全球二氧化碳排放量在2020年大幅下降了6.3%。

Renewable energy consumption has tripled in 10 years
Renewable energy was the one category that bucked the global trend of declining energy consumption in 2020.
Despite the 4.5% decline of primary global energy consumption - the largest since World War II - global renewable energy consumption grew by 9.7% in 2020. That was a slight decline from its 12.2% pace the year before, but it’s remarkable given how significantly the pandemic impacted total energy demand.
Renewables were the only category of energy that grew globally at double digits over the past decade. For perspective, in 2010 the world consumed 9.6 exajoules of renewable energy. In 2020, that had tripled to 31.7 exajoules.
The renewables category above consists of wind power, solar power, biofuels, geothermal energy, and power produced from biomass. The BP report further breaks down renewable energy consumption into just power production (i.e., without biofuels), and that accounts for 88% of all renewable energy consumption.
Within the Renewable Power category, wind (50.6%) and solar (27.2%) accounted for most of the consumption. Although wind consumption maintains a healthy lead over solar consumption, solar power consumption continues to grow at nearly double the rate of wind power, and is likely to overtake it as the leading source of renewable power this decade.
Despite the blistering growth rate of renewables, it’s important to keep in mind that overall global energy consumption is growing. Even though global renewable energy consumption has increased by about 21 exajoules in the past decade, overall energy consumption has increased by 51 exajoules.
Increased fossil fuel consumption made up most of this growth, with every category of fossil fuels showing increased consumption over the decade (although coal’s growth was close to zero).
Thus, while renewables have helped reduce the growth of carbon dioxide emissions, global carbon emissions have grown due to the overall growth rate of fossil fuel consumption.
However, because of the decline in overall energy consumption in 2020, renewable consumption did grow faster than overall energy consumption. In turn, global carbon dioxide emissions decreased by a whopping 6.3% in 2020.
