Solar wind combo

It's estimated that 18,000 of the 250,000 residents of the Navajo Reservation don't have electric power. Distributed, off-grid solar-wind generators, which are owned by the rural utility and rented by residents, have been installed at about 200 homes in a program that was started in 2000. Some of the early systems ran into trouble when people tried charging them with diesel generators, but the Johnson family has not had any major problems with theirs.
