Saving energy

In the UK, home energy contributes around 22% of the average carbon footprint, with over half of this coming from our heating systems. This means we can significantly cut our carbon footprint through a few simple home energy efficiency improvements.

The Energy Savings Trust has developed a tool to calculate how much CO2 and money you can save by applying some of these measures. Examples of 11 easy, effective, cost-saving actions are listed here, with figures based on a three-bedroom, semi-detached, gas-heated house.
