The digital revolution sweeping the energy sector would seem poised to help reduce the greenhouse gas emissions that cause climate change. Progress in artificial intelligence and computing power, the plunging cost of sensors and other digital equipment, and rising connectivity could all make it easier to use clean energy sources and cut wasteful energy use.

Yes, but: Digitalization is a double-edged sword. Unless policymakers around the world act quickly, it could make the global energy system dirtier. Policies such as carbon pricing are needed to steer the energy industry toward digital technologies that reduce emissions rather than raise them.
