In January of 2016, in collaboration with his coauthor, Leah Y. Parks, he will publish a new and important book about our energy future: All-Electric America: A Climate Solution and the Hopeful Future. The book is scathing but optimistic, and manages to be bold while remaining pragmatic. Drawing on their combined years of experience, Freeman and Parks make the case for addressing the dangers of climate change with some concrete steps to counter our current downward spiral. Mr. Freeman argues that we will soon be able to power all of our energy needs with electricity generated completely by renewable energy as well as with increased energy efficiency in heating, cooling, lighting, transportation and our electric grid. The authors point out that:
Transforming our entire energy infrastructure to run on renewable energy by the year 2050 will require a larger effort than solely switching out our current electricity capacity. Investments in coal mining, oil and gas drilling and building new large coal, gas, and nuclear plants will give way to a massive increase in the construction of solar and wind power plants.
