Don’t Forget Solar Thermal Power
It is easy to get all excited about making electricity with solar panels, but electricity isn’t the only thing the sun can do. It makes heat. Using a solar water heater is a whole lot simpler and cheaper than making enough electricity to run an electric water heater. Online, you can find plans to build a unit that fits into a window that will help heat your house. With a solar oven, you can even cook a meal. With a magnifying glass you can start a campfire with the sun’s heat.
Don’t overlook solar thermal power. Even my cat knows how to harness the sun’s heat on a cool morning.
