Clean Energy coming of age

I have looking for a good picture that shows the relative cost of Clean Energy vs other Energy sources over time. I finally found one from Hudson Energy, that is just great. In the diagram below, you can see the relative costs as well as their growth in utilisation over time. It is just the US market, however due to relative price parity across markets, I will assume that the diagrams of cost at least are similar across the rest of the globe.

It basically shows that Wind and Solar will be very similar in cost to other energy sources within the next decade.
