可再生能源首次超过油气为英国提供40％的电力

据能源之声5月21日消息称，分析显示，今年前三个月，可再生能源发电量占英国总发电量的40%以上，首次超过化石燃料。

风力发电场在电力结构中与天然气竞争榜首，发电量占总发电量的30.5%，仅次于化石燃料，后者在1月至3月间占总发电量的30.6%。

今年2月，英国遭遇了有记录以来最潮湿、风力最强的严重冬季风暴，这是有记录以来的第一个月，全国风力发电场的发电量超过了燃气发电站。

伦敦帝国理工学院学者为Drax Electric Insights做的分析还显示，自3月底开始的限电令，导致工作日的用电量下降了13%。

工业、办公室、学校中机械、电脑、灯和加热器的使用减少，以及电轨、有轨电车、地铁服务的减少导致工作日电力需求降至1982年以来的最低水平。

该研究称，尽管由于人们白天呆在家里，家庭用电量有所增加，但对于工作日的电力需求来说，这“就像度过了一个月的星期天”，而在周末，电网的用电量甚至更少。

禁令对碳排放产生了影响，英国电力生产的排放量比去年同期下降了35%。

与去年同期相比，暴风雨条件下创纪录的风力发电量使化石燃料发电量下降了25%。

与2019年第一季度相比，每单位发电量的排放量下降了20%。

这一趋势将持续下去，今年将有更多大型海上风力发电场投入使用。

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.
