To see an interview of Lester Brown by Richard Heinberg of the Post Carbon Institute, see http://www.postcarbon.org/video/83004-post-carbon-exchange-1-richard-heinberg In this premier Post Carbon Exchange, Post Carbon Institute Senior Fellow Richard Heinberg talks with Lester Brown, Founder of the Earth Policy Institute, about hopeful developments in alternative energy, as well as the importance of Brown’s updated path toward a sustainable future, “Plan B 4.0”.

Here are some highlights from the accompanying data on three types of solar energy: solar photovoltaics (PVs), concentrated solar thermal power (CSP), and solar water and space heating.
