I lived for 25 years, off the grid on solar power til my house burned down. I could do it, but a lotta people frankly, are just too stupid. They cant remember to turn off the TV or the lites. They cant remember to check the battery bank, or reduce consumption during the low lite time of the year.
Short Mountain in Tenn does it, but they are a *commune* and have the people who are enthusiastic about solar power to keep an eye on the system. They use one central main kitchen & lounge so that all the 'homes' need is a bedroom lamp.
If you want to move twards a sustainable global system, the nuclear family home is going to have to be abandoned. You need the energy efficiency of communes. I'm all for the various pilot projects, but the investment per capita needed for a solar nuclear family home is way beyond the average global family income. Its only when you move up an order of magnitude to the village or communal house scale that it becomes affordable in anything other than the richest economies.
