The cheapest power is the power you do not use
Every unit you save is a unit you never have to buy, generate or store. That is why efficiency comes before solar in any good plan.
Lighting
- Replace old bulbs with LED lamps, which give the same light for much less power and last far longer.
- Use daylight where you can, with light-coloured walls that reflect it.
- Switch off lights in empty rooms, or fit simple timers or sensors in corridors and security areas.
Cooling
- Use ceiling or standing fans first. They use a fraction of the power of an air conditioner.
- If you need air conditioning, choose an efficient model sized to the room, and keep doors and windows closed while it runs.
- Shade and a reflective roof reduce how hard it must work.
Other big users
- Refrigerators: keep the back ventilated and the door seals tight.
- Water heating: heat only what you need, or use a solar heater.
- Standby power: switch devices off at the socket when not in use.
Do the sums
Compare the price of an efficient appliance with its running cost over its life. A product that costs a little more but uses much less often wins in the long run.
