How the 2018 summer heatwave impacted the nation’s energy use

We look back at how the 2018 summer heatwave impacted the UK’s energy consumption.

This summer was constantly compared to the blistering heatwave of 1976 – in fact, it came so close that it was widely reported as the joint hottest summer since then.

Met Office data reveals that 1976 was the hottest summer on average, though only by a small margin (0.33oC). Despite this, when looking at the average temperatures throughout June, July and August, 2018 still appears more frequently in the top three hottest months than 1976.

June 2018: 2nd hottest June on record
July 2018: 2nd hottest July on record
August 2018: 25th hottest August on record

June 1976: 3rd hottest June on record
July 1976: 5th hottest July on record
August 1976: 5th hottest August on record

Using this year’s scorcher as an example, investigators have researched how our behavior during the summer heatwave has impacted the nation’s energy consumption at home.

BBQs:
In July, John Lewis reported their sales of BBQs had increased by 67%. By barbecuing more than usual this summer, estimators think as a nation, we used 430,920,000 kWh less energy than we would have if we used conventional hobs and ovens. This saves enough to power 130,006 average-sized homes for a year.

Electric Fans:
While our appetite for al fresco dining may have reduced our energy use, the cost of keeping cool this summer soared. Research reveals that internet searches for “fans” rose by 140% in 2018 and sales doubled compared to summer last year. What’s more, four in five fan owners were found to switch it on at night, in the hope to keep cool and get some sleep.

By correlating demand with Met Office weather data, Estimators think the total energy consumed by leaving fans on overnight this summer was 723,672,000 kWh. That’s equivalent to powering a whopping 233,443 homes with electricity for a year (or the same as half the size of Cardiff).

Fans are by far the more purse-friendly method of keeping cool though – depending on wattage, sleeping with your fan on every night for a week costs up to £0.98, whereas aircon could set you back £10.85 a week.

Being outdoors:
With the hot weather and lower than average rainfall for the most part of summer, even those not actively looking to save money and energy likely did so by spending more time outdoors. A study found that 23% of us were encouraged by the hot weather to spend more on outdoor activities and experiences, getting away from televisions and games consoles at home.
