With the technology that we have this is quite possible. Only, too many people are getting rich keeping that umbilical cord attached to your house.
40 years ago I personally knew a man in Ohio who attempted just that. He had his own wind generator. He had a pit filled with rocks that he heated by sunlight in the summertime which kept him warm in the wintertime. He had many other energy saving devices. Dayton Power and Light made life very nasty for him.
There are many cases where Amish people are forced to hookup to power companies.
Back in South Dakota in the 40s the government forced people, through REA, to have every farm and ranch hooked up to electricity. Some of those ranchers were forced to pay 50 miles of power lines and step up transformers. My father installed Windcharger unit to electrify the ranches. The government changed enough laws so that now the rancher and farmer has to have that power line hooked up to their property.
Right now, for me, I live in a small town in Kentucky. Right off the bat, I can't put up a clothesline to dry our clothes. Do you realize how much power storage it would take just to run a dryer? And that is just the beginning. I can't have a garden so we have to have refrigeration for a lot of food that we didn't need energy for when I was a kid out on the farm in South Dakota.
Then there is the case of those people in Kentucky who wanted to live the life that Gore has proposed for us. They bought a lot of land and were in the process of building shelters and such. The Child Protection Service took their kids away because they didn't have several things, one of which was electricity.
So technically it could be doable but first of all you would have to slightly lower your living standards and then fight the government. I have better things to do with my life so I give in.
I think Kano has the real answer.
