How renewables will change electricity markets in the next five years

How renewables will change electricity markets in the next five years | Sustain Our Earth | Scoop.it

Photovoltaic (PV) cells, onshore wind turbines, internet technologies, and storage technologies have the potential to fundamentally change electricity markets in the years ahead. Photovoltaic cells are the most disruptive energy technology as they allow consumers of all sizes to produce power by themselves—new actors in the power market can begin operating with a new bottom-up control logic. Unsubsidised PV markets may start to take off in 2013, fuelling substantial growth where PV power is getting cheaper than grid or diesel backup electricity for commercial consumers.
