There is a world of difference between your neighbor who went to Woodstock, and folks who are growing commercially. Even with that said, many people are now getting into cogeneration, and multiple power inputs tied to the same off grid network (solar, wind, water turbines, backup dino sources). Alternative power has come a long way.Looks like something some potheads would do. I'd think any self-respecting pothead would only be using offgrid solar. Nasty ole dino juice is just not prog.
