More humans than ever before live in cities. Technology is now being rolled out across the world’s urban areas, making day-to-day city living more pleasant, more efficient and more sustainable. For example, traffic flows are being improved by sensors that detect snarl-ups, allowing a central computer to coordinate traffic lights and even change the direction of a highway during rush hour – saving commuters time and lowering the pollution caused by stop-start congestion. Smart energy meters are allowing the power companies to provide the energy we need from the best sources, at the right times of day. But what we’re already seeing is just the beginning. By using computing, automation and big data, the cities of tomorrow will be transformed by practical, disruptive solutions, helping us tackle the energy challenge and achieve a lower carbon future. But there’s a flip side to letting technology take over the way our cities are run. Automation opens up systems like traffic, communications and power to hackers a
