By replacing oil heating with natural gas, you can cut 35% of your CO2 emissions; by switching from electric to natural gas heating, you can cut them by 60%.

56

Turning down the heat by 2-3°C at night while you are sleeping saves you up to 10% of your heat consumption.

57

Fine-tune your heating system. By keeping your furnace clean, lubricated and properly adjusted, you can save up to 5% in heating costs.

Buy a programmable thermostat, which can regulate different temperatures at different times of day – and if you already have one, use it. These thermostats reduce energy use by 5-30%.

59

Every time you lower the temperature in your home by 1°C, your energy consumption drops by 5%. 

60

Sealing your windows and doors properly will drastically improve your household fuel efficiency. Sealing air leaks and adding insulation can reduce your annual energy bill by 10%.

61

Double-glazed windows lose only half the heat of single-glazed windows. If everyone in the UK fitted double-glazing, nearly five million tonnes of CO2 would be saved – the equivalent of 800,000 households' total emissions.

62

Radiators fitted to exterior walls can lose up to 70% of their heat to your bricks and mortar. Insulating panels reflect heat away from the wall and into your home where it belongs. Fitting radiator panels will save around 80kg of CO2 a year and cut heating costs.

63

If everyone in the UK put an insulation jacket on their hot water tank, CO2 emissions would be cut by 740,000 tonnes. This would shave £89 million off their combined annual energy bill.

64

About 42% of your household energy costs go towards just two things: heating and cooling. By replacing old heating and cooling systems with newer, efficient models, you can cut your annual energy costs by 20%.årligt. Ordentlig isolering ville reducere CO₂-udledningen betydeligt og skære op til 20% af varmeregningen.
