Indeed, politicians in the employ of the (traditional) energy sector have gone from mocking renewable projects and decrying them for "requiring subsidies" to demanding their curtailment because they do not.
Alberta's government (whose premier is a former oil&gas industry lobbyist) enacted a "moritorium" on new renewables projects a couple years ago because it had the most active investment in that sector in the country (most sunny days, and very windy). After the moritorium was lifted draconian regulations were placed on potential new sites.
This was done under the cover of "protecting farmland", but this is in a province with a massive abandoned oil well contamination issue, which the private sector got away with and continues to get away with.
And then today/yesterday it came out that the government had hidden the results of public "consultations" on these matters because it was not favourable to them.
The problem with oil&gas is it is prone to the development of parasitical/highway-man type relationships, and all sorts of people get rich quick by inserting themselves in the flow and they will not give up this position without a dirty, dirty fight.
