トレンド 1990 - 2020 - TWh





2020年には世界の電力消費量は1.1%落ち込みました。2019年の減速はあったものの、これは2009年以降初めて の落ち込みであり、2009-2018年の期間には安定した伸びがあったのとは対照的です。 世界の電力消費量の29%を占める中国は、COVID-19危機から迅速な回復を見せ、電力消費量は2020年に3.1%の伸びを記録しました(2019年は4.5%の伸び、2000-2018年の期間は年間平均+10%の伸び)。 他の国々では、COVID-19が電力需要にはるかに強い影響を与えました。特に一部のOECD諸国では、既に下降トレンドを持っていましたが、工業および商業の分野での需要が低下しました。電力消費量は、アメリカ合衆国(-3.9%。2年連続の低下)、欧州連合(-4.3%。ドイツ、フランス、イタリア、スペインで急減)、英国、日本、韓国、カナダでも落ち込みました。電力消費量は、2000年以降電力需要が急増したものの2018年に減速していたインドでも低下しました。また、ロシア、ラテンアメリカ(特にブラジルとメキシコ)、アフリカ(主として南アフリカとアルジェリア)でも減少しました。中東では横ばいになりました(イランで伸び、他の国々で落ち込み)。

According to Ireland's Environmental Protection Agency, the country's greenhouse gas (GHG) emissions decreased by 3.6% in 2020 to 58 MtCO2eq. The decrease in emissions is reflected in most sectors with the exception of increases in residential, agriculture  and public services. In the energy sector, GHG emissions fell by 7.9% (-0.74 MtCO2eq), as peat-fired power generation halved and renewable power generation increased noticeably (+15% from wind), covering 42% of the Irish power mix. Residential emissions grew by 9% (+0.59 MtCO2eq), as a result of colder temperatures, historic low oil prices (impacting heating choices), and home working. Emissions from transports fell by nearly 16% (-1.9 MtCO2eq) due to transport restrictions. Overall, Ireland's GHG emissions are still only 7% below 2005 level. The country committed under an EU agreement known as the Effort Sharing Decision to cut GHG emissions by 20% between 2005 and 2020.



According to the Global Wind Energy Council (GWEC), 6.1 GW of offshore wind capacity was installed in 2020 (down from 6.2 GW in 2019), including 3 GW in China, 1.5 GW in the Netherlands, and 0.7 GW in Belgium. More than 35 GW of offshore wind capacity is currently operational, with 29% of the total in the UK, 28% in China and 22% in Germany.



South Africa’s total greenhouse gas emissions excluding FOLU (forestry and other land use) increased by 14% between 2000 and 2017 to 513 MtCO2eq, according to the country’s 7th National Greenhouse Gas (GHG) Inventory Report. The energy sector is the largest contributor to emissions excluding FOLU (80%) and is responsible for 97% of the increase over 2000-2017. Energy industries were responsible for 61% of emissions from the energy sector in 2017. This was followed by transport (13%), other sectors (9%) and manufacturing industries and construction (7%).



According to the Turkish Electricity Transmission Corporation (TEIAŞ), installed wind capacity in Turkey reached the 10 GW threshold in early August 2021. Most of the capacity is located in the Izmir province (1.7 GW), followed by Balıkesir (1,300 MW), Çanakkale (850 MW), Manisa (750 MW), and Istanbul (420 MW). Wind represented 10% of the installed capacity connected to the transmission network (10,010 MW out of 98,800 MW) and over half (51.9 GW) was considered "clean" electricity. In the first half of 2021, wind power accounted for around 9% of the power generation, replacing nearly US$1bn in gas imports.
