Not just the outlay for hardware and software but what the day-to-day costs really are. If you assume a 20 hour a week habit and using $0.11 a KWH. Actually playing costs Geoff $30.83 a year. If Geoff turns his PC off when he is not using it he could save $66 dollars a year. Turn off your PC when you aren’t using it. The environment will thank you and so will your wallet.
