Many of us are constantly looking for ways to save money: using fuel-efficient cars, clipping coupons, buying energy-efficient appliances, eating at home, and other changes. What many of us overlook, however, is the vast amount of money we could save by using solar energy in our homes. There are three main ways to use solar energy at home. First is solar electricity, in which a solar panel system provides the electricity to run the entire household. Second is passive solar power, which directly uses the heat from the sun. Last is the use of independent solar appliances that include their own solar panels.
