Hawaii mandates solar hot water heaters

Hawaii has become the first state in the nation to require that all new homes come equipped with solar water heaters. The new law will apply to homes built after January 1, 2010, and add about $5,000 to a home’s cost. Solar water heaters pay for themselves in a few years because they cut average electricity costs by 30-35%. Israel and Spain also require solar heating in all new homes.
