I saw something a while back that worked out that leaving a computer on sleep overnight used about the same energy as 30 seconds car travel at 40mph. Can't remember where and the figure was probably way out.
Anyone with a mild obsession for energy consumption want to work out some handy conversions between (say) leaving Apple laptops/desktops on sleep [1], boiling full kettles for just one cup of tea, leaving car engines idling, hoovering, and leaving the freezer open by mistake?

[1] I presume there's a difference?

I read somewhere (can't find it now) that the Mini uses 2-3W - 'fraid I can't be any more mildly obsessive :-).

If you accept 2.5W and you assume a car at steady 40mph eats 10KW (13.4HP), then a mini sleeping overnight (8 hours) is more like 7.2 second's travel. 72,000 Joules. That's £0.0004 at 5.6p per KWH At that price, your personal daily share of the world's sunlight is worth about £30,000.
