Off-grid officially since March 4, 2011.
Since 1980 I had a desire of being able to power my home independently from commercial power. Between 2009 and early 2011 I had been extremely close to achieving that goal. I had been hesitant to cut the cord though. A perfect storm of bureaucracy in the local electric co-operative finally convinced me. I have not regretted shutting it off.

From way back when I found the pictures on the left. In 1980, while in college I became interested in solar power. I constructed a panel from 36 Radio Shack 1 amp cells that the local store had to call most of the other stores in the state. The cost was around 10 dollars per cell. I fiberglassed a plywood board and used silicone caulk to place the cells on the fiberglass. There was a lot of heat stresses and at the time I didnt really understand all the "right" ways to do it. It worked for about a year. I kept a plexiglass cover on them when I wasnt around. Even with that I accidentally left the cover off one day and some pea size hail obliterated it. I ran one light bulb and an Ten-Tec Argonaut 509 off of it.
This wind generator is located in Ashmore, IL.
