Richard Heinberg of the Post Carbon Institute interviewed Lester Brown on his latest version of "Plan B: 4.0". Lester confirmed in his interview what Johann Hari said in Democracy Now: that local, grassroots environmental campaigns have successfully stopped the development of new coal-fired power plants in the US, just as Climate Camp did in the UK. Furthermore, he said that older plants are being converted to cleaner fuels or shut down because of direct action and public pressure. Interestingly, Lester said that in 2009, more money was invested globally in renewable energy sources such as wind, solar and geothermal than was invested in fossil fuel production, a first in modern history.
