How Today's Technology Can Save Our Climate and Clean Our Air

by Mark Z. Jacobson, with a foreword by Bill McKibben. 

The first edition of this book, No Miracles Needed, was a Cambridge University Press' "Book of the Year" (link)

This new edition was published on January 22, 2026 and is now available from Cambridge University Press (link) or Amazon (link) or Barnes & Noble (link). For additional questions, please contact Matt Lloyd at Cambridge mlloyd@cambridge.org.

The world needs to switch away from using fossil fuels to using renewable sources of energy as soon as possible. Failure to do so will lead to accelerated and catastrophic climate damage, loss of biodiversity, and economic, social, and political instability. This book describes how to solve the climate crisis, and at the same time eliminate air pollution and safely secure energy supplies for all - without using miracle technologies. It explains how to use existing and known technologies to harness, store, and transmit energy from wind, water, and solar sources to ensure reliable electricity and heat supplies worldwide. It also discusses which technologies are not needed but are currently being pursued, including fossil gas, carbon capture, synthetic direct air carbon capture, blue hydrogen, bioenergy, and nuclear energy. Written for everyone, Still No Miracles Needed advises individuals, communities, and nations on what they can do to solve the problems, and discusses the economic, health, climate, and land benefits of the solutions.
