About

More so than ever before, the United States is powered by a diverse mix of energy sources. The interactive diagrams that follow explore the past, present and future of this complex system. The first maps out the composition of our primary sources of energy — from crude oil to solar power — and their different uses. The second visualization explains how those energy sources have diversified since the 1700s. The final diagram shifts to a global view, to show how — despite growing domestic energy production — rising demand overseas is intensifying competition for all types of energy.
