I admire your optimism :-) but I'm not 100% sure that is true. If there wasn't a political drive behind this, wouldn't it have been easier to burn coal for the next 100 years?
There are lots of examples of innovations changing entire industries without a political drive being behind it. The day someone discovers a clean energy method that is easily cheaper than fossil fuels will be able to cash in because the market will switch to it quite handily, regardless of politics. The only political drive I really worry over with things like this is cronyism that prevents innovations in an effort to maintain status quo.
This is already happening. Rooftop solar is disturbing monopoly utilities who are trying to stop it from disrupting them by slapping charges on customers who use it, or refusing to allow them to connect.
In the UK, a government with ties to fossil fuel industry (where the money is centralised and easy to syphon into bribes and kickbacks) is sabotaging wind power in favour of fracking.
Abbot in Australia etc.
The technology is already there, it's all about the politics now.
