use electrical stoves

t is estimated that 50% of the tyres on the road are under-inflated, which increases resistance and raises your fuel consumption. Driving with soft tyres can add up to 2% to your fuel bills, the RAC says. So keep your tyres inflated to the correct level. See your car's manual for the recommended pressure, check your tyres once a week and use the air pump at your local garage.

Air conditioning uses up to 25% more fuel, according to the National Energy Foundation, so don't use it unnecessarily. Switch it off and open your air vents instead, or just have the window down. But if you're travelling at more than 60mph and it's too hot, you're better off having the air-con on instead of keeping the windows down. Open windows increase drag, which at high speeds can cost you more in fuel than having the air-con on.

2. Maintain your motor

Inefficient, under-serviced engines can reduce fuel economy by 10% or more. So have your car serviced regularly. Dirty air filters can seriously reduce your fuel economy, according to the RAC. So change them regularly. They are inexpensive and easy to change if you have your car's handbook. Similarly, have the oil in your car changed regularly. Having clean oil reduces the wear caused by friction of moving engine parts, and helps improve fuel consumption.

Make sure your petrol cap fits tightly – petrol will evaporate if the cap is not airtight.
