You know I read a long time ago of a town that was helped by government to install solar and wind power systems personally. This private 'power grid' was then pushed onto the national power grid during the hours it was not being used. For example, while the people were out at work, all the power that was collected was pushed onto the grid, then when they needed the power from the national grid, it was taken with the power credit offset against the cost. Sound like a great idea.....I would buy into something like that for sure!
