The absence of "regular" human activities has dramatically affected our environment for the better. In this book, Bob McDonald turns his focus to global energy sources, and shows how the global shutdowns may have been exactly what we needed to show us that a greener future is achievable. This is an exploration of the incredible technologies that our species can use to get out of the mess we've made for ourselves. It is a work of immense optimism, to counteract the sense of doom that hangs over most discussions of the environment. Green technology is one of the fastest growing sectors of the economy, and will only continue to skyrocket as current products improve their performance and new products emerge. A new green age is upon us--let this book be your guide to the future.
