Yes, we are talking about base load. We have about a football field's worth of spent fuel sitting in casks and pools. That's not per reactor; that's in total in the US since we started running nuclear power stations. In fast neutron reactors, this could power all of the US electrical needs for 150 years without requiring any new sources of uranium (no mines, no seawater extraction, nothing!) AND would eliminate the need for 100,000+ year geological storage.
Far more compact than batteries, wouldn't compete with other large scale transitions that need batteries like electric cars, and would work even during either a week-long blizzard, tornado, or hurricane.
Batteries offset the power needs from dusk to dawn, but most solar farms do not build capacity for extended (multi-day to week) outages. A single tornado let alone a hurricane could wipe out gigawatts of solar or wind capacity. Containment domes on nuclear reactors by contrast wouldn't even blink at these kinds of natural disasters.
We need solar. We need wind. We need geothermal. We need hydro. And we need nuclear to completely eliminate most fossil fuels from our energy cycle. We need some of all. Diversification in energy sources is a good thing.
I strongly disagree that everyone needs the same solution. Some nations are extremely rich in wind while others are mostly devoid of it. Nations like Iceland have a ridiculous surplus of energy due to geothermal resources. Some nations have easy access to hydro while most don't. New Zealand could probably power twenty New Zealands on wind alone. Even in the US we see this in play. The South/Southeast have little to no wind resources at all but are VERY sensitive to severe weather events that would tear apart large solar arrays leaving millions without power for fall too long. In the North and center of the US, wind power is almost a no-brainer. High, consistent winds across the plains could offset many other forms of electricity generation, especially away from large bodies of water. Geography strongly guides which solutions are available.
The US produces over 37 billion metric tons of CO₂, making the U.S. responsible for 14% of global emissions on its own. Regardless of what other nations do (and I hope they continue toward de-carbonization), the US must take an aggressive role in reducing its own fossil fuel emissions within its borders, since those are the only emissions we can directly control. Diplomacy and economic incentives can only go so far across international borders, but building an maintaining ties overseas is obviously of great importance for that reason. None of this "America First" crap.
As for domestic production of electricity, we are already out of sync with countries like Iran, regardless of what Israel does or does not do. We have 93 nuclear power plants. Iran has 1. The nuclear power (and weapon) genie is already out of the lamp. Everyone knows how to make a nuclear plant today. That said, Israel (and Iran) have other options like PV and especially solar thermal. They exist in a region where thermal masses could be used to great effect without concern of Plutonium proliferation.
We absolutely, positively do NOT need every nation to get their power from the same sources. We only need them to get that power from sources other than fossil fuels.
