"[1] we should keep rolling out renewables as fast as we can. But [2] we should also fix the unnecessarily difficult regulatory environment for advanced nuclear"

[1]: sit on hands and watch existing markets follow their current trajectories. Odds of success: excellent. [2]: make a major change in the existing political economy of energy, beating all the entrenched interests who will oppose it. Odds of success: ___________.

Costa Rica, Iceland, and Uruguay run almost entirely on renewables. Other countries are catching up quickly.

I said wind and solar, not "renewables." Countries with large hydro and geothermal resources can easily run on those, because they're always available.

We really need two different words: one for hydro/geothermal which are steady supplies but geographically limited, and another for wind/solar, which can be installed anywhere but are unpredictable and require massive storage or fossil/nuclear backup. The use of the same word for both has been a constant source of misleading rhetoric.

Iceland is a tiny country with lots of geothermal energy. Comparing that directly to the US, makes zero sense.
