If you live in an off grid home on a river, a River Turbine could be your key to 24/7 power production - without having to worry about shade or night time, as you would with solar. Idenergie River Turbines can be placed in as low as 2 feet of water. If the river has a nice steady current, it can generate up to 12kWh of power daily - which could power most of your off grid needs!
