When I first read the titile, I thought that the US is going to have to build A LOT to triple global production. Then it occured to me that the author means the US is pledging to make deals and agreements which enable other countries to build their own. Sometimes I think the US thinks too much of itself and that's also very much part of American branding.

Where are my renewable bros at? Tell me this is bad.

The time from inception to going online for a new Nuclear reactor is in the range of 15-25 years. Of course we could attempt to shorten that, but that would probably mean compromising on safety

It also takes 20years for a tree to grow, so I guess we should stop planting trees too. Good logic.

The rest of what you are saying is ignorant at best. "Global construction capacity" is constrained to current levels. How convenient that we can only build exactly the number of nuclear reactors we are currently building. But we can build an unlimited amount of solar panels, wind turbines and "hyrdo."

How long do you think it takes to "build hydro?" If you ignore any and all environmental costs of flooding valleys, then sure I guess you could do it pretty quickly, you'd probably have to relocate hundreds of thousands of people, but sure that sounds more feasible then building a nuclear reactor.

Current Nuclear energy production is non-renewably because of cold-war era treaties against enrichment and breeder reactors. The timeline for nuclear fuel to run out if you allow breeders, is after the sun burns out. So that's a non-issue. Not to mention other theoretical sources of nuclear fuel that we don't bother even looking at because it's cheaper to burn more coal.

If you read my comment, I specifically add a caveat for hydro.

In terms of solar and wind, of course we cannot just build unlimited amounts, but we can ramp up capacity a lot more easily and quickly than with nuclear, because it's a lot simpler and faster to build (especially solar). Imagine if we increase construction capacity by 10x tomorrow; we would still need to wait for 15 to 25 years to see any impact with nuclear, while solar and wind would go online next year.

Of course, ramping up production brings an increased risk of manufacturing faults and construction errors in all cases. But I would argue that any nuclear accident is a lot more undesirable than some solar or wind power going offline.

In terms of nuclear fuel, these alternative technologies may exist. But again, the time to market, and the fact that we are introducing a new technology into our vastly expanding production capacity just brings even more risk and uncertainty, which is completely unnecessary when extremely save and reliable, well tested alternatives exist (solar and wind).

So what I am arguing is that we focus our limited resources and money (the latter being the key factor in our economy, unfortunately) on the things that have the largest impact in the shortest amount of time, and that is solar and wind (and to an extent hydro).

And again, all that analysis is graciously disregarding the very real risks of nuclear power (instability, war, proliferation).

I disagree. I think that people make fewer mistakes in each repetition, the more times they repeat an action.

Right now nobody has mastered the building of nuclear plants. As a civilization, we’re on the equivalent of our third day on the new job. If we committed to tripling world supply, that would lead to us mastering it. We’d be at the equivalent of having been at the job for a couple years.

What does "mastering it" really mean? Usually a big part is learning from mistakes. Which I do not think is something you want to do with nuclear power.

But here is the thing. There is no resource constraint between building nuclear power and building solar or wind, or even hydro. They use difference resources, they require different sectors of the economy to realize, and they require different engineering. They don't compete with each other except in the minds of people who favor one over the other for some reason.

Nuclear competes with fossil fuels, that's it. So do renewables, but on a much more limited basis. They do not compete iwth each other. No individual or government is ever looking at a choice between Wind power and Nuclear power and choosing one over the other.

Except for funding, obviously.

And as I said, the main point is we need clean, renewable energy as soon as possible, which only solar and wind (and to some extent hydro) can provide.
