Average laptop power supply is about 90w. An ultra-powerful laptop, like my i7 hexacore, comes with a 240w power supply.

If you run it at full power, 24x7, with an average power cost of 12 cents per kWh, I think you might end up spending $50 bucks a year. You’re not going to do anywhere near that.
