It's important to understand that not only the opinion changes, but the situation in itself. Producing renewables is now much cheaper than a few years ago. Production processes are getting more efficient, thus less co2 intensive and energy conversion rates are getting better. A few years ago it maybe was not clear that people had a legitimate interest in renewables. The producing companies probably do not care about the environment outside of laws, but if the request for renewables is high enough, a market can emerge and prosper. This is very hard to predict even for smart economy people unlike me.
