I ordered this new book and recommend it highly. It actually shows you how to measure the amount of energy that your car really needs!! (as opposed to how much gas it eats). It also shows you how to measure the difference of energy used at low speeds and high speeds, lets you calculate the engine’s energy efficiency, and how your car’s energy compares to other things like energy in your home. It also discusses wind and solar energy, as well as electric and hybrid cars along as well as Vehicle to Grid (V2G) technology. This book is awesome!
