“We built a small data centre in Exmouth leisure centre. Most normal data centres waste the heat that the computers generate. We capture ours and we give it for free to the swimming pool to heat the pool,” Bjornsgaard told BBC Radio 4’s Today programme.

The technique works for the data centre and the pool – the heat from the computers warms the water and the transfer of heat into the pool cools the computers.

“It’s great for them – they get to reduce the cost of heating the pool and reduce the amount of carbon they use, and good for us because we can offer cheaper computer services because we don’t have the cooling costs,” Bjornsgaard said. “We built a small data centre in Exmouth leisure centre.

Domestic appliances including fridges and freezers, cookers, washing machines and dryers, dishwashers, TVs and electronic displays, and lighting, come with energy efficiency ratings. These labels have been recently updated ranging from A, the most efficient, to G, the least efficient (A+s has been removed). The labels also show the energy consumption of the appliances and, where relevant, water consumption.

When homes are sold they are given an ‘energy performance certificate’  that shows how well the place is insulated and how efficient is its in terms of the energy used. The certificate may also point out where improvements could be made. A second certificate records the ‘environmental impact (CO2) rating’ and measures the carbon footprint for the unit. Both range from A, being the most efficient, to G, least efficient.

Saving water and saving energy often go hand in hand. Showering less often (swop for a daily wash) saves both water and energy used heating the water. Ditto if you wash your clothes less often. 

As our hot water tank is upstairs and the kitchen sink down stairs, we realised that to get hot water from the kitchen tap we were drawing an extra 5 litres of water. By heating water for washing up in the kettle we have saved both water and electricity. (One kettle provides for one washing up cycle).
