A path to sustainable energy by 2030.

by Mark Z. Jacobson and Mark A. Delucchi Executive Summary The plan below demonstrates how the world can feasibly produce 100% of its energy by 2030 from sources with near-zero lifetime (including construction, operation and decommissioning) emissions of greenhouse gases and air pollutants. Only technologies available and scalable today are included. These include wind, water, and solar (WWS) for power, and battery and fuel cell vehicles (including airplanes) powered by WWS electricity and hydrogen split from water, respectively, for transportation. The obstacles to a clean-energy future are largely political, not technical.
