For all you naysayers (like us) who doubted that solar energy would ever become a mainstream phenomenon, we offer two words: Home Depot.
The home-improvement empire has partnered with BP Solar to provide solar-power systems, according to Treehugger, with services that include free home consultation, installation and follow-up inspection. The Home Depot solar page also links to a national database of state incentives for renewable energy and a special calculator so you can estimate your potential savings. (We also had our doubts about this whole Internet thing.)
