Modern society is dependent on flexible electrical energy, available on demand and at an affordable cost. Most of our electrical energy is produced by converting the carbon stored in coal or natural gas into heat energy and then via a turbine into mechanical energy. But as we increase the amount of less-dispatchable renewable energy into our electrical systems we have to be much smarter about the way we use energy.
