How to be energy-wise in summer

Here are some low-effort, high-impact ways to work with your energy this summer:

1. Be the biggest ‘fan’ of keeping cool:

We all know fans are great at keeping you cool, and bonus, they use less energy than an air conditioning system! 

However, fans don’t actually lower the room temperature; they create a cooling airflow that helps evaporate moisture from your skin. To chill the breeze even more, try a couple of frozen water bottles in front of the fan - it will create a DIY mist-like effect. 

In the evening, you can effectively push warm air out of your home by creating a home-made crosswind. Place a fan facing out of an open window and another facing inwards - this should help draw warm air out whilst also circulating cooler air into the room. 

Top tip: Give your fan regular cleanings and clear any dust from its blades, air inlets, and vents. Make sure to unplug it first!

2. Shade from the rays:

During the daytime, we recommend keeping your blinds and/or curtains closed during the hottest periods. This will keep the room cooler and allow fans to work more efficiently. 

In the evening and/or morning, try opening windows at opposite ends of your home (when the air is cooler). This can help let refreshing air flow through your property.

3. Ditch the tumble dryer:

Tumble dryers are one of the most expensive appliances in our homes, so any excuse to cut them out for a few months is great for our wallets (and the planet!).

Hang clothes outdoors or on drying racks indoors (they'll dry faster if hung in direct sunlight!).

4. Keep in the chill:

Fridges and freezers work harder to stay cool in the summer, but there are a few things you can do to help them out:

• Give your fridge door seal a quick inspection for any warps or tears that might break the suction. While you're at it, wipe away any hidden grime to ensure a perfectly airtight snap every time you close the door.

  
  

• Try to avoid leaving the door open longer than you need - this lets warm air into the fridge, making it work harder to maintain its set temperature. 

  
  

• With BBQ season in full swing, it can be tempting to cram your fridge full of yummy food, but crowding the shelves can prevent cold air from circulating. Take a bit of time to clear out your fridge and make sure things are evenly spaced.

5. Give your cooling system a cleanup:

Just like heating systems, air conditioning systems need regular maintenance to ensure they can cool homes properly. This includes making sure the condensing unit is clear of debris, ensuring the coils are clean and cleaning/changing any air filters. If you’re unsure, check your AC user guide or seek help from a professional. 

Portable AC units are also effective, but pricey to run. According to the Energy Saving Trust, they cost nearly 20 times as much to run all day compared to a standard fan. To maximise the chill without the high bill, make sure you keep the filters and coils clean (turn it off at the wall first!), and switch it off when you’re not in the room. 

Top Tip: Close doors and windows when using air-con to speed up air cooling. 

Bonus: Make sure you choose the right air conditioning unit for your room size!

6. Turning the heat down for your bills:

Ditching your oven in favour of lower-wattage countertop appliances like air fryers, slow cookers and microwaves will save you money and keep your kitchen cooler.

Top tip: For extra savings, fire up the BBQ and enjoy cooking al fresco!
