Saving Energy Facts
How expensive is energy?
- Energy costs have risen seven times faster than household income since 2004
- A typical home now pays £1,400 a year for energy (2013)
- Nearly 25% of homes can't afford enough energy to keep healthy
How much can we save from better efficiency?
Energy consumption for heating has reduced by 20% in last 10 years due to improved insulation and more efficient boilers (Ofgem-2013)
- Cavity wall insulation reduces wall heat loss by up to 53% saving £140 (EST)
- Loft insulation can reduce roof heat loss by up to 94% saving £170 (EST)
- Solid wall insulation reduces wall heat loss by 85% saving up to £490 (EST)
- Double glazing reduces window heat loss by 74% saving up to £170 (EST)
- A new gas boiler is about 25% more efficient than a 20 year old boiler saving up to £270 a year
- A 6W LED light replaces a 60W tungsten bulb saving 90% on lighting costs
How much can we save from changing our habits?
Simple things can add up to significant amounts of energy and hundreds of pounds saved. Try:
- Switching things off when they're not is use
- Closing curtains at night when the heating is on
- Cooking with the lids on saucepans
- Using a microwave rather than a cooker
- Taking a shower rather than a bath
In many cases a knowledge of the amount of energy actually consumed by an appliance, particularly on standby, is all that may be needed to encourage you to switch things off.
Here is a typical selection of household equipment that tends to left on 24 hours a day but won't be harmed by switching off:
- Wireless broadband router 13.5Watts= 118kWh/yr= £24/yr
- Satellite/Cable TV box 40.0Watts= 350kWhr/yr=£70/yr
- Mobile phone/laptop charger 15.0Watts= 131kWh/yr= £26/yr
- 42inch Plasma TV 21.0Watts= 184 kWh/yr= £37/yr
(These are all based on standby or their lowest state of activity and assume 24hr a day in this state with electricity at 20p/kWh.)
