Worldwide industrial energy consumption is expected to increase 42% from 2007 to 2035, with 95% of growth in developing nations. China has surpassed the US as the largest energy consumer, accounting for 20.3% of global demand compared to 19% for the US. Existing smart energy monitoring solutions have shortcuts like lack of context awareness, complex implementation scenarios, and difficult interaction. The IoT is proposed as an alternative approach using technologies like sensing, data transmission, analytics, and context-aware decision making to create an energy monitoring system called ENEMON that can be used in various scenarios like home monitoring and controlling, industrial monitoring, and smart metering.
