Digital technologies are everywhere, affecting the way we live, work, travel and play. Digitalization is helping improve the safety, productivity, accessibility and sustainability of energy systems around the world. But it is also raising new security and privacy risks, while disrupting markets, businesses and workers. Digitalization & Energy is the International Energy Agency’s first comprehensive effort to depict how digitalization could transform the world’s energy systems. The report examines the impact of digital technologies on energy demand sectors, looks at how energy suppliers can use digital tools to improve operations, and explores the transformational potential of digitalization to help create a highly interconnected energy system. This report seeks to provide greater clarity to decision makers in government and industry on what digitalization means for energy, shining a light on its enormous potential and most pressing challenges. It also lays out no-regret recommendations to help steer the world towards a more secure, sustainable and smarter energy future.
