Charity Engine is one of the greenest computing resources on the planet. We only use spare processing power from PCs that are already switched on for other work.
But even more impactfully: 75% of a computer's lifetime energy cost comes from manufacturing, not running it.
That means the greenest computing service is the one uses servers built for other purposes.
And it means the greenest thing you can do with your PC is make the most of it – and that's exactly what Charity Engine does, by putting your idle time to work for great causes.
