"Oil wells go dry and coal seams run out, but for the first time since the Industrial Revolution began we are investing in energy sources that can last forever." –Lester R. Brown, Plan B 4.0: Mobilizing to Save Civilization.
Need data? Sometimes numbers can tell a story. Here are some of the figures from the behind-the-scenes research for the latest book from Earth Policy Institute, Plan B 3.0: Mobilizing to Save Civilization, by Lester R. Brown. Complete data sets and charts are now available.
