Interesting, but I am not sure how useful it is if referred to the whole world.
There seem two distinct steps in the trace, perhaps exaggerated by the scale being logarithmic, but if real what happened there? They are around 2005 and 2012.
I wonder if the cost is falling too? It may do, in some countries, but could be affected by more than ordinary technical and commercial considerations and likely to become more affected still.
