We use almost exclusively electrical energy in our facilities to do all of our powering. Most facilities around do that. Not too many are self-sustaining, although I have this dream that one day we can co-digest anaerobic sludge from the waste water treatment plant, and sludge from our SSO facility at our waste water treatment plant in either Clarkson or Lakeview, and produce enough power so that you have an off-loop plant treating waste. I think that would be cool, but most of our energy uses electricity.
