Gas-powered politics

America's fracking revolution has made the US the world's largest oil and gas producer and that's had political consequences the world over. Manuela Saragosa speaks to Meghan O Sullivan, professor at Harvard Kennedy School and author of Windfall: How the New Energy Abundance Upends Global Politics and Strengthens America’s Power. Morena Skalamera, assistant professor of Russian Studies at Leiden Univesrity, talks about the effect on the giant Russian gas producer Gazprom; and we hear too from Trevor Sikorsi, head of natural gas and carbon research at the consultancy Energy Aspects.
