Thread: fusion vs.wind vs.solar
They all power any harvester or factory. However, the Potential Energy of a power supply determines how many power units you get per unit of resource. For 500 and below, it's 1-for-1 (deposit one unit of power, one unit of the resource is removed from your inventory). At around 750 I think it hits 2-for-1 (deposit two units of power, one unit is removed from your inventory). I think it caps out at 4-for-1 at around 950 PE.
Wind tends to have lower PE than solar, which tends to have lower PE than radioactive. Plus, all power generators (wind, solar, ion fusion) cost the same 60 credits per hour to run, but the fusion can have an extraction rate up to 14 units/minutes.
So from a cost standpoint, getting a fusion generator is the best route to go. The harvester extracts more power than solar or wind, and tends to have better Potential Energy. Of course, they go for about around 80-100k to purchase, so you may have to stick to the lower generators until you make some cash.
If you're just purchasing energy off the bazaar or from a resource vendor, look for the highest PE you can get.
