DesertDrifter -- in the musing re renewable, was thinking ahead, as the whole electric power setup continues to evolve in coming years -- there are significant advances well on the way in both the efficiency and cost of solar panels, and the capacity, reliablity/durability and cost of both battery and capacitor storage -- as well as in terms of using solar in single, integrated units/panels to directly split water to produce H2 for storage (H2 storage another area of rapid progress) for use in e.g. fuel cells, which in their own turn continue to become more efficient and reliable/durable and less expensive
I believe that within if not 10 then 20 years, there could and likely will be millions of homes/smaller structures, with or without growrooms, very nicely and cost-effectively entirely powered and heated by on-site direct solar-to-H2 to H2 storage to fuel-cell setups, with enough H2 left over for back-up/supplemental heat, cooking, and a fireplace or two (and fuel for any new, or vintage hot-rod, piston-engined vehicles [which, properly set up, run very well on {>130 octane RON http://en.wikipedia.org/wiki/Octane_rating } H2]) -- ideally with also a solid layer of solar to electricity to electricity storage integrated into the on-site system (and/or maybe even some small-scale on-site wind power, the electricity from which could be used/stored directly and/or used for supplemental H2 production, as needed, if they ever manage to get that cost-effectively figured out) -- with one end result being that any connection to either the electrical grid or the natgas grid would be strictly optional
