Well, let me clarify my statement. At this point, I'd expect large solar and wind plants to be competitive with fossil fuels. The problem would be with storing power, so that it will be consistent. My previous post was referring to individuals, rather than businesses. For a homeowner to install a PV system, based on your link, it would cost around $18,000. You wouldn't break even on it for 20 years, and that's assuming that you're still tied to the grid. Once renewables are both cheaper than fossil fuels, and in reach for the average person, mass adoption will quickly follow.
