This document discusses next generation energy management and sustainability. It notes that while energy demand is rising significantly by 2050, carbon emissions must be curbed to avoid dramatic climate change. This creates conflicts around resource access and control. The document advocates that energy efficiency is crucial and more cost effective than increasing supply. It also notes that smart grids and smart buildings can interact to optimize efficiency across energy generation, transmission, distribution and usage. Technology is presented as an enabler to achieve sustainability goals through solutions like demand response, distributed energy resources and energy management systems.
