Sign of the times: Hawaii is now requiring all new homes to be outfitted with solar water heaters. The new law passed by Republican Governor Linda Lingle prohibits issuing building permits for single-family homes that do not have solar water heaters, with exemptions for homes in low-light regions. How long before other sunny states follow suit?
We'd most definitely consider investing in one of these systems except their prices is still cost prohibitive for renters like ourselves. Hopefully in due time the market, demand and maybe even state subsidies will bring solar heating into the realm of reason for moderate income households. In the meantime, we'll stick with using less water in the tub and decreasing the temp (easy anyhow, since it's been so warm).
