According to that graph, onshore wind has been cheaper than fossil fuels since 1995. What will be different about the next 20 years that this price difference will suddenly cause a huge surge in adoption, when it has already been cheaper for decades without making a huge impact?
I can't answer that and aslo I know people who are "deeper into this", this being energy economics, that can't agree either.
The fact is that the bids for offshore wind has been going down for a while now.
