Solar and Wind power was completely blocked up by conservative governments all over the globe for the past 50 years. Consider Reagan, who removed solar panels from the roof of the white house just a few years after they were installed and not long after multiple oil supply crises in the 70s. Even if the solar panels being installed in the first place was only symbolic, removing them was also purposefully symbolic.

America at least had a great chance to invest in nuclear energy and completely end dependence on the middle east for it's energy, but it chose Reagan instead.
