Every year the cost of power generation projects are changing in function of technological changes, changes in prices of supplies or due to economies of scale.
NREL has recently publish the 2016 version of the Baseline of Cost and Performance of most technologies used nowadays for power generation showing the flat trend of prices for conventional energy and the impressive decline in prices that have renewable energies, especially Solar PV with Capital Costs of up to 0.9 [MM USD / MW] for PV at utility scale.
I’m excited to think that the day has come when renewable energy is economically competitive with traditional energies and has reached the point where they no longer need subsidies to displace old and polluting forms of energy production.
Clearly the future is greener…
