Save energy by not turning clocks back in October, says expert |
Prof Aoife Foley says it would remain light for part of energy peak between 5pm and 7pm, reducing household bills
Households could save more than £400 a year on energy bills if clocks are not put back at the end of October, according to an expert, who said it would help people with the cost of living crisis and reduce pressure on the National Grid this winter.
Evening energy demand peaks between 5pm and 7pm during winter, when the sun has already set after daylight savings time (DST). If clocks didn’t go back, it would remain light for at least part of this time, reducing carbon emissions and energy demand.
Prof Aoife Foley, a clean energy expert at Queen’s University Belfast, said: “By simply forgoing the winter DST in October, we save energy because it is brighter in the evening during winter, so we reduce commercial and residential electrical demand as people leave work earlier, and go home earlier, meaning less lighting and heating is needed.”
This would help the government tackle the “energy war” in Europe resulting from the Ukraine invasion, she said. “Dependent on weather conditions this winter it is very likely we may need to start rationing energy very seriously to avoid bigger energy issues in December and January when gas reserves start to run low,” she said.
Foley’s calculations suggest that households could save £1.20 a day and more than £400 a year on electricity bills if clocks are not put back at the end of October, although exact amounts depend on tariffs.
There has long been debate over whether to scrap DST, which was introduced in 1916 to reduce energy demand during the war by prolonging evening daylight in summer. It still benefits some farmers, but is less popular among people who would prefer more light later in the day in winter, and is thought to cause sleep disturbance. It was originally proposed in 1907 by William Willett, a builder and the great, great-grandfather of Coldplay’s Chris Martin, who is well known for the song Clocks.
The European parliament voted to scrap the hour change in 2019, and a poll showed that most EU citizens agreed. But the change has yet to be implemented and no longer applies to the UK after Brexit.
Foley did not include gas savings or electricity and gas in the commercial or industrial sectors in her calculations, but she said these would offer “even more significant energy, cost and emissions reductions”, flattening the evening peak on energy demand by up to 10%.
Some critics of scrapping daylight savings are concerned about road traffic collisions, but Foley’s research suggested most road deaths occur in good visibility during the day and outside built-up areas, and usually on a Friday, Saturday, Sunday and Monday, with speed, tiredness and alcohol the main factors.
