We had a wind generator but the last 60 mph wind took it out. In 15 years, the only other maintenance we did was to replace the blades after another wind storm and keep water in the batteries. We'll repair this one and though we love it - we won't be adding much wind in the future.

We have solar pannels on the Electrak and plan on adding more "dedicated" units as time and money allow. The cost of the panels has gone down dramatically and we've installed reflective material on one of the buildings to park the E-Trak next to to reflect more light in the evening. The tractor is stored indoors in an un-heated building over winter and that's just as well since the batteries are so cold they won't do much anyway.

 

The Premo-Power is Hydro-Power. A manual about it is available online at smallHydroPower.com and we plan on making our own system by floating a barrel with the generator inside so it floats with the water depth. Larger water wheels can also be made from recycled barrels like the old days systems.

And finally, as the back-up to the back-up system is a generator unit - store bought and modified to also heat water from the exhaust.
