The United States is in the throes of two unfolding energy revolutions. And partisans, convinced that only their side holds the key to American prosperity, security, and safety, are battling over which one should prevail. Oil and gas production, after decades in decline, are being propelled upward by new technologies and high prices, prompting enthusiasts to predict an economic renaissance and impending energy independence. On the other side of the fight, more efficient cars and trucks are increasingly dominating the road and costs for renewable energy have plummeted, leading many to herald a starkly different future that moves beyond fossil fuels and saves the planet. Both unfolding revolutions in American energy offer big opportunities for the country to strengthen its economy, bolster its security, and protect the environment. Speakers: Michael Levi, Meghan L.
