He's not the only one.
Aww, libertarians, how cute. The magic of "everything will sort itself out if you just don't look at it funny"
Yes, renewable energy shouldn't get subsidies, once it establishes itself. But you need to invest into new tech before it can stand on it's own. You also need to realize the difference between subsidies and a government choosing to actively phase out dirty energy like coal, gas, oil. Free market would dictate that the best offer would win but what is best right now might not be best in the future.
"No regulations" is the same hilarious talking point libertarians are so rightfully mocked for. No regulations won't stop a company from dumping toxic sludge into rivers or filling the air with pollutants. No regulations won't stop a company from using asbestos to line everything.
Real conservatism means finding the pentagon toilet seats that cost 500$ and making sure you get cheaper toilet seats from now on and only as many as you need. Real conservatism means cutting redundant programs but not cutting every safety net a citizen has and let him fend for himself.
That being said, i only found libertarian talking points on that site you provided and i am not going to spend hours looking up absolutely everything about them. If you have in mind a specific proposition they are supporting, we can discuss it.
