TOH projects, such as the one in 2007 in Austin, have incorporated tankless (or instantaneous), indirect, and solar hot-water systems—all proven technologies that can save money over their lifetimes when matched to a household's needs. But even basic water heaters sold today are much more efficient than older ones. Homeowners with one that's more than 10 years old should consider replacing it; a new one could even pay back with a rebate from the power company or the government.
"We've showcased a lot of energy-saving technologies over the years, and we'll keep on doing so, because we need them more than ever."
