the easiest way to do lots of wind would be to have EDF as a monopoly provider and investing in a coherent national plan to put as many wind farms as possible, finding the least objectionable sites to do so, and imposing, at the same time, that the manufacturers put their factories in France as a quid proquo for getting large guaranteed orders over the next several years.

Barring that, public support via (i) feed-in tariffs and (ii) consistent and stable permitting procedures are enough, in nomal times, for the industry.

In today's market, if funding is still an issue, then a public entity to provide funding to banks (which would keep project risk) would certainly help and would be very simple to set up - that entity would simply take bank risk (which we're doing by the shitload already anyway) and the banks could continue their business or wind risk assessment normally.

In the long run, we're all dead. John Maynard Keynes
