Hi. Fellow Ohio permie here. We should hang out sometime.
I think that individual solutions are different from mass solutions. An individual solution is something like a woodstove, while a mass solution is something like using all the waste heat from the Perry nuclear plant to heat homes.
Even on an individual level, you has to ask whether you want your solution to be scalable or not. Personally, I am plan to build a net zero energy house (tons of insulation), and utilize nut shells as a primary heat source. This requires a few acres of nut trees. Not so scalable, but I think it will work for me.
