Smart city projects are what people hear about most and they get a lot of attention, among others because smart city applications are close to the daily lives of residents. Another reason why smart cities are often mentioned is that de facto smart city projects account for a big portion of Internet of Things deployments. Think about smart waste management (often a local matter), smart parking and environment monitoring. In recent years, there has been a growing environmental movement around the world as we seek to avoid a climate catastrophe. One of the main questions in this arena is how to create renewable energy in the most efficient and cost effective way. For many in the Smart Energy industry, Smart, or Internet of Things devices could be the answer.
