Farms: On Earth Day, world turns attention to renewable energy

Wednesday marked Earth Day, and the focus around the world is on renewable sources of energy. One of Germanys biggest energy companies, RWE, is about to invest $650 million to build wind farms in Poland. Poland now relies overwhelmingly on coal to produce its electricity, but has launched a major new initiative to power itself using so-called lean energy sources. Olav Kjorven, director for the United Nations Development Programs Bureau for Development Policy, joins Martin Savidge to discuss how sustainable development can be encouraged in very poor countries and how, given the current global economic crisis, to counter those who say these its simply too costly to go green.
