Because the money for politics is in oil. Renewables are investing any dollar they have into building more. Oil has a lot of money that is best invested in politics thus creating the political will.

Don't worry too much, the return on investment of renewables is much better than politics. Politics can put a few brakes on, but that only slows things a little, it won't stop it. (and politics is not set - there are plenty of forces opposing oil - they are not in power now but they are still powerful and are likely to gain power again as the tides switch)
