But look at the capital expenditure of doing it vs the running cost
saving. Waiting till the old bulbs blow might even be worthwhile!

And how the MTBF of your hard drive, computer and stereo bits falls
under the influence of power cycling. There use to be a general
statement about HDD's maybe 5 years ago that said if you leave them on 8
hours a day you might as well leave them on 24 hours.

Other big savers are;

- Lower your hot water service temperature
- Use full washing and dishwashing loads
- Lower you thermostat in winter and wear a sweater/coat
- Check central heating/cooling units for gaps/holes in the ducting and
fix. Also check window and door openings
- Shorten freezer/fridge opening times
- Let your cooking "coast" (unpowered) for the last few minutes on the
hotplate

There are obviously a host of others but these would be the biggest.

A HWS is about 1500W and some central heating is about 4500W.
