Low oil prices are sending shockwaves through the global economy, and longtime industry observer Dieter Helm explains how this and other shifts are the harbingers of a coming energy revolution and how the fossil fuel age will come to an end. Surveying recent surges in technological innovations, Helm's provocative new book documents how the global move toward the internet-of-things will inexorably reduce the demand for oil, gas, and renewables--and prove more effective than current efforts to avert climate change.
