據能源之聲5月21日消息稱,分析顯示,今年前三個月,可再生能源發電量占英國總發電量的40%以上,首次超過化石燃料。
風力發電場在電力結構中與天然氣競爭榜首,發電量占總發電量的30.5%,僅次于化石燃料,后者在1月至3月間占總發電量的30.6%。
今年2月,英國遭遇了有記錄以來最潮濕、風力最強的嚴重冬季風暴,這是有記錄以來的第一個月,全國風力發電場的發電量超過了燃氣發電站。
倫敦帝國理工學院學者為Drax Electric Insights做的分析還顯示,自3月底開始的限電令,導致工作日的用電量下降了13%。
工業、辦公室、學校中機械、電腦、燈和加熱器的使用減少,以及電軌、有軌電車、地鐵服務的減少導致工作日電力需求降至1982年以來的最低水平。
該研究稱,盡管由于人們白天呆在家里,家庭用電量有所增加,但對于工作日的電力需求來說,這“就像度過了一個月的星期天”,而在周末,電網的用電量甚至更少。
禁令對碳排放產生了影響,英國電力生產的排放量比去年同期下降了35%。
與去年同期相比,暴風雨條件下創紀錄的風力發電量使化石燃料發電量下降了25%。
與2019年第一季度相比,每單位發電量的排放量下降了20%。
這一趨勢將持續下去,今年將有更多大型海上風力發電場投入使用。

Renewable energy powers 40% of UK as it outstrips oil and gas for first time, analysis shows
Renewables generated more than 40% of Britain’s power in the first three months of the year – overtaking fossil fuels for the first time, analysis shows.
Wind farms were vying for top spot with gas in the electricity mix, generating 30.5% of power, just behind fossil fuels which contributed 30.6% between January and March.
Severe winter storms in the wettest and windiest February since records began helped make it first month on record when more electricity was produced by wind farms than gas-fired power stations across the country.
Analysis by academics from Imperial College London for Drax Electric Insights also shows that weekday power consumption fell by 13% as a result of the lockdown which began in late March.
A lack of machinery, computers, lights and heaters being used in industry, offices and schools, and a reduction in electric rail, tram and Tube services led to weekday electricity demand falling to its lowest levels since 1982.
Although domestic power use increased due to people being at home in the day, it is “like living through a month of Sundays” for weekday power demand, while weekends have seen even less electricity needed on the grid, the study said.
The lockdown has seen an impact on carbon pollution, with emissions from British power production falling 35% on the same period last year.
Record levels of wind power in the stormy conditions helped push down electricity generation from fossil fuels 25% compared with the same period last year.
Emissions per unit of power produced were down 20% on the first quarter of 2019.
The trend is set to continue, with more large offshore wind farms coming online this year.
