Dr. Rajeev Shah is the president of the Rockefeller Foundation and, as world leaders gather for the United Nations General Assembly, he argues that nothing matters more to individual well-being than energy, which is what leaders need to focus on. As he writes: "Electrifying the world could produce the largest development gains since the 1990s. Electrification is about more than progress for individuals; it makes the world safer and more secure. High energy prices are straining livelihoods at a moment when coups, migration and unrest are destabilizing regions. And because the countries where energy access is lowest are projected to produce as much as 75 percent of greenhouse gas emissions by 2050, connecting people there to clean energy can help prevent climate catastrophe for us all."
