As the Canadian comment process finishes, as an American incandescent ban largely finishes on January 1, and as the EU review process also seems to have concluded in its first phase, some concluding remarks to the last series of posts seems apt.

The coming of solar grid parity offers an opportunity for millions of Americans to go solar affordably. But it also means a potential transformation, a democratization of an electricity system long dominated by centrally-controlled utilities and centralized ownership and production of electricity. When solar can undercut grid electricity prices, it may also undercut this 20th century system of centralized ownership, bringing economic sunshine and self-reliance to communities along with solar electricity.
