I think a lot of it has been driven indirectly by vehicle regulation. The past few years have seen several major countries establish end-dates for gasoline powered vehicles. This has spurred development of battery technology - very important for wind and solar - and also sent a market signal about the future role that fossil fuels play in global society. Even if a country hasn't explicitly banned fossil fuels yet for electricity generation, the writing is on the wall and it's only a matter of time. Investors and corporations are seeing that renewables are an inevitable future, and adjusting their strategies accordingly.
