Solar Water Heating : This can save your household up to 35% of its energy use and up to 80 tons of carbon dioxide from entering our environment over the life of the system. There is a federal tax credit and many states offer additional tax credits, as well. Solar water heating systems actually pay for themselves and then make money! Every day 5,000 times more energy shines down on Earth from the Sun than it takes to power the entire US! Harness some of that to lessen energy costs.
