Summer Energy Consumption

As you may know, it was recently Summer Solstice, also known as the longest day of the year. On 21 June, the earth witnessed 16 hours and 38 minutes of daylight, more than usual. This implies that summer is well and truly underway – we can now enjoy the brighter evenings. But, does this mean at a cost?

The irony: cooling makes the planet hotter.

On average during the summer, we spend around £50 per month on energy usage in our homes – in comparison to £120 in January. This highlights how people tend to enjoy the weather in different environments and do not rely on electricity in their homes for entertainment or comfort. This leads us to wonder… can we get this cost even lower?

The Environmental Impact Assessment (EIA) expects that during the months of June through to August 2019, it is predicted that energy consumption will total about 9% lower than summer 2018. The usage will also be about 3% lower than the average of the previous 10 summers.

However, there is a rising demand for air conditioning and refrigeration which threatens to make the planet hotter. As a result, over the next 15 years, according to the EU, the energy used to cool buildings across Europe is likely to increase by 72%, while the energy used for heating them will fall by 30%.

Cooling technology is part of our energy footprint and we rely on it. It is believed that by mid-century, people will use more energy for cooling than heating. Air conditioning, using fans and refrigeration usage can cost your business, school or home more than necessary if your energy efficiency plan isn’t up to scratch.

How can I reduce my summer bills?

Not only will reducing your consumption save money, but it will help the environment. After all, the importance of green credentials has never been greater. Here are some of our tips to help you cut your costs:

  • Realistically, there is no need to have the heating on, at all. Summer is all about wearing less and leaving the windows open. Although, if you find that your building is chilly in the mornings, find ways that heat is leaving your building, i.e. through cracks in the walls, and fix them. Equally, using an automatic thermostat on a timer will emit your preferred temperature.


  • On the other hand, when buildings are too hot… use a handheld or table fan. Fans use a lot less energy than air conditioning systems. This means that more money can be saved.


  • Draw the curtains and blinds to help keep out the sun’s warmth. This prevents homes, buildings and classrooms from being over heated.


  • Making sure that air conditioning units are running efficiently is another way to help conserve energy during the summer months. If you are to use air con, make sure that the system is working properly. The most important maintenance task that will ensure the efficiency, is to routinely replace or clean its filters. Cleaning or replacing filters is an easy task that only takes a few minutes to complete, where a clean filter can make an air conditioning unit 5-15% more efficient than a dirty one.


  • Lighting in offices create further heat, so try and use natural light if possible. If not, and your workplace is still using incandescent light bulbs, consider replacing them with energy efficient bulbs. These types of bulbs can give out brighter light but can use up to 70% less energy than a normal incandescent bulb! They also tend to have a better life span, meaning bulbs will not need to be replaced as often.


  • Using a smart meter is a useful device which allows you to get smart with your energy. Trimming your energy bills is now easier than ever as the software sends automatic readings to your energy supplier. This allows your industry to keep track of exactly how much gas and electricity you’re using, so that bills are more accurate. Similarly, a smart meter tracks what appliances you are using the most, suggesting how to reduce this.
