I think part of the desire for renewables is the desire to be free of the monthly utility bills; in my case ,the government allows me to use a large enough land area that wind-driven generators, biomass gas converters, alcohol stills, solar panels, and low-head hydroelectric turbines COULD provide ALL the energy my family could use. Of course, the initial costs of construction of all these things would be many times more than the cost of purchased energy.
I say , allows me to use, BECAUSE, if I do not pay property taxes every six months on the land and improvements like buildings and energy gathering devices, the gov't will send a man with a gun toi take it away from me. (This is why property taxes are a great evil;I pay tax on my earnings,tax again on my purchases, and yet more tax for permission to keep my purchases.)
