They're not, of course. They're an easy thing that everybody can do. And if everybody does it (switch to low-energy lightbulbs) then it makes a big difference.
Reducing your home heating bill isn't quite as straightforward. But it has the potential to make a much bigger impact than changing lightbulbs - both on your own fuel bills and on your carbon footprint.
I made a list of ways you can reduce your home heating bill, and none of them involve turning the heating off and shivering:
- Add to your loft insulation
- Make sure you have cavity wall insulation
- Install double or even triple glazing
- Exclude draughts
- Close curtains when it gets dark.
- Make sure the curtains have thermal lining
- Put foil behind radiators
- Turn off radiators in unused rooms
- Use timers to make sure the heating is only on when it needs to be
- Wear a jumper
- Turn down your heating thermostat
If you can think of any other things I could add to the list, do let me know. Notice that turning down your thermostat is last on the list. Once you've made your house more insulated and draught-proof you'll want to turn your thermostat down anyway because you'll be far too warm.
I tried to pick one of these things for March's challenge, then I thought - let's do them all. So that's this month's challenge. Every time you do one of the things on the list, vote in the poll. Even if it only makes a 5% difference in your home heating usage, that will swamp any saving you could make in lighting, appliances, leaving gadgets on standby, or any other single part of your domestic energy budget.
