I have asked our sustainability expert Franz Nahrada for more comprehensive reporting on this, but I would like to point our readers to a site I have just discovered, New Rules, which reports on advances and obstacles to electricity users and local communities generating their own power (and hence also sharing or selling it). I have added the particular pages that are of interest in a delicious tag on P2P Energy. The site shows in details what local, state, regional and federal measures are being taken to advance this agenda (in the U.S.).
