Cost & Carbon

Speed rules, but let's not go broke or melt the ice caps in the process, eh?

Based on our numbers, at the US average of 4.4 hours a day of intense gaming, plus everything else you do on your machine, a typical rig might use 1400 kilowatt-hours of electricity a year (550W GPU), or about $200 in energy bills at typical US prices.  In addition, depending on how dirty your local utility is, your rig could easily be spewing 1500 pounds of the greenhouse gas CO2 into the atmosphere at the same time.    That's the middle of the range.  How bad can it get ...?  ... Over $1000/year and 5000 pounds of CO2!

Here's a table with some more scenarios.   Bottom line.  Save energy: save money and save the earth and game another day.

40 cents/kWh??  Yeah, really.  In many areas, electricity prices increase in a stairstep fashion as consumption rises.
Your gaming rig could put your bills over the top!
