On the Roof: Why Solar Hot Water is Sexy

In tomorrow's Wall Street Journal, my job drives me to the roof -- no, not to jump -- but to explain the merits of a solar hot water system.

It's simple, and can get you out of roughly two-thirds of your hot water bill. Plus, the tax incentives to install one are pretty sweet -- cutting costs nearly in half in some cases.

Everyone thinks of electricity when they think of solar. But this is an easy and cheaper way to start cutting your energy costs. That's sexy in my book.
