    Though a lot of the green crowd have been big proponents of solar cells, solar cells are pretty nasty beasts containing gallium, tellurium, and other heavy metals and nasty components . . . manufactuering them also produces a significant amount of nasty byproducts and waste.

    One things that I've never seen is the lifetime and disposal costs of solar cells . . . that never seems to be factored into the so called "solar renewable energy" equation.
