I have had a look at folding and dont mean to be tight, but if my cpu is running at 70-100% surely this is going to cost me quite alot more than if it's sat idle! Is it you lot are rich or am i missing something?

yup, it will cost you more as the CPU will consume more energy.

Nice explanation here;

But please note that CPU power consumption has been dropping a lot the last few years and continues to do so. As the size of the core is reduced (and things like like dual core is introduced i guess?*) you shorten the difference between idle and 100% cpu load in power consumption.

Also running on laptops (even at full speed) with mobile processors consume very little power. My laptop - when running at maximum performance - consumes a total of 25W, for all components in total, as opposed to 6W in extreme idle.

Edit: *) When thinking pr. processor.
