Our current electricity system is in trouble.
Under investment in research and development has left us with grid infrastructures which are crumbling.
To fix this we need to start rolling out smart meters, smart grids, super grids and market based demand response - this will more closely align the electricity demand curve, with the supply curve (which is now becoming less controllable with the advent of renewables).
Automated demand response programs are our best hope for successful DR programs. That and intelligent appliances which can adjust their behaviour based on information feeds from utilities about the state of the current (no pun) market.
