But this problem wouldn't occur with solar energy right??,(reply>), @Roxor128 ohhhh thankss for the knowledge,(reply>), Happens with solar, too. Can be fixed with batteries. If you've got the money for a big enough solar array and battery bank, you can run your house with no grid draw and have your grid connection as an income source, rather than an expense.<br><br>There is one case where it doesn't happen with solar, and that's a molten-salt solar-thermal power plant. Those store the sun's heat in molten salt for generation after the sun goes down.
