What if we don't need 'miracle technologies' to solve the climate problem? What if the technologies we need are already available? And what if we can use those existing technologies to ensure reliable electricity, heat supplies, and energy security? In a revised and updated edition of his award-winning climate bestseller, No Miracles Needed, the world's premier thinker on energy futures and 'one of the world's 100 most influential people in climate policy', Mark Z. Jacobson reveals how nations, communities, and individuals can solve the climate crisis most effectively, while simultaneously eliminating air pollution and providing energy security. Mark explains how existing technologies can harness, store, and transmit energy from wind, water, and solar sources to ensure reliable electricity and heat supplies. It includes new, cutting-edge technologies, additional new real-life case-studies about the solutions, and additional references. Written for everyone who cares about the future of our planet, this book advises individuals, policymakers, communities, and nations about what they can do to solve the problems identified, and the economic, health, and climate benefits of the solutions.
