How to save energy in summer

1. Let the light in 

Make the most of natural daylight by opening blinds fully during the day and turning off indoor lights when possible. You could even rearrange your workspace or living area to maximise the use of sunlit spaces – especially if you’re working from home. This is great for your circadian rhythm too. 

Fans use significantly less energy than air conditioners – usually under 0.01 kWh compared to up to 3 kWh – making them a more energy-efficient and cost-effective way to cool down. For that reason, resist the temptation to air conditioning unless you really need to. To eliminate your energy consumption here completely, try these low-energy cooling tricks instead: 

• Close curtains during the hottest part of the day to keep out direct sun. 

• Open windows in the early morning or late evening to let cooler air flow through. 

• Use lightweight bedding and breathable fabrics to reduce the need for artificial cooling overnight. 

3. Fresh air > fuel 

Electric bikes and scooters are everywhere now – and for good reason. They’re quick, convenient and far better for the planet than jumping in the car. Not only does this cut emissions and reduce fuel costs, it can actually be quicker for local errands. Plus, with drier weather and longer evenings, summer is the perfect time to adopt this healthy habit. 

If you’re heading further afield, consider trains, coaches or electric vehicles where possible. Fewer car journeys mean fewer emissions and less air pollution, which is particularly important during hotter months. 

4. Check your fridge and freezer settings 

Fridges and freezers often work harder in warm weather, especially if they’re placed in hot kitchens or opened frequently. You can reduce the strain by: 

• Keeping them well-stocked (even if just with bottles of water) to retain cool air. 

• Making sure seals are tight and airflow isn’t blocked. 

• Defrosting regularly to keep them running efficiently. 

5. Cut down on cooking energy 

Oven use can heat up your home and demand more from your fridge. Lighter summer meals like salads, stir fries or one-pan dishes can help reduce your energy use, whilst making the most of seasonal produce. Batch cooking and using microwaves or air fryers instead of the oven are other great ways to keep energy use down and still eat well. 

6. Make use of the sunshine 

Summer is ideal for air drying clothes, which can help you avoid the tumble dryer altogether for weeks at a time. What’s more, according to the Energy Saving Trust, drying clothes on racks inside or outside could save up to £55 per year! A portable dehumidifier is also a great option. 

If you’ve got solar panels, try shifting your usage to the sunniest parts of the day. For example, running dishwashers or washing machines mid-morning when solar generation is at its peak.
