Think about converting your water heater to solar energy. A water heater can represent upwards of thirty-five percent of a single home's energy use. While these costs may be lower upfront than the full power ones, solar water heaters can save you money sooner.
A solar powered fan for your attic is a good choice if switching completely to solar power is not feasible. The fan will have a temperature sensitive gauge and switch itself on when necessary. This will remove heat and lower the cost of cooling. It's also solar powered, so you don't have to pay to power it.
Solar Energy in our Atmosphere notes.
Consider your home's outside design when thinking about solar energy. Having solar-powered pathway lights installed outside is an easy way to use solar energy at home. If you're building a home, positioning it so that it can take advantage of the sun's rays is also beneficial. Well-oriented homes filter in winter sun rays in the south-facing windows and that can reduce heating bills.
