Edit:
Do the downvoters really think the above scenario is acceptable? Being limited on where you can go, what chargers you can use and the increased time to go places?
Sorry but that's a ridiculous comparison, I just want to be able to drive to places my current gasoline vehicle can travel to, but in an electric car. Also there are large numbers of people out west camping, climbing, skiing, etc on all sorts of remote backcountry roads far from services. Its the reason many of us live out here.
In Utah and Wyoming you can be on the interstate and still be far from a gas station[1]. I don't think most people who don't live out west are aware of how remote parts of this country truly are.

A single wind turbine can contain 3.6 tons of copper[1], so using your source for uranium used by a nuclear power plant in one year. Just seven and a half wind turbines use as much copper as a nuclear power plant uses uranium in one year.
If you replaced the ~100GW of nuclear power capacity in the United States you would need about 360,000 tons of copper. It would take the current US nuclear fleet ~133 years to use the equivalent amount of uranium. The above also assumes that wind turbines runs at 100% capacity which we all know they won't. So your going to need an additional 2 - 4 times more turbines and copper to replace the current US nuclear fleet.
> Furthermore copper concentrations are typically around 100 times higher than uranium concentrations, which means you need far more uranium ore than copper ore to produce the same weight of metal. Copper has been extracted with relative ease for thousands of years.
Also copper concentrations in typical copper ore is not 100 time greater than uranium concentrations. Copper concentrations are about 0.6%[2] and uranium is 0.1% - 0.2%[3].

Mining is not besides the point, mining is a potential major bottleneck for renewables and has huge environmental costs that should be discussed. Also Tesla is trying to reduce the ecological and human costs of producing battery metals by bringing production/mining to North America, and switching to battery chemistries that don't use cobalt. However those non cobalt battery chemistries use lots of nickel. Also it is becoming extremely difficult to start a mine in the United States. Polymet has been trying to get their copper/nickel mine permitted for over a decade, if you include exploration, which started in the 80's, this project has been going on for decades. Starting a new mine is a very slow process and as the whole world switches to clean energy, demand will surge and new mines will be needed.
> You seem to imply that a scale change is needed on the mining front to bootstrap renewables. I doubt that that's as big of a deal that you seem to imply.
There is plenty of research, articles and information about the incoming surge in demand for metals due to the switch to clean technologies. For example this report from the world bank says that production of some metals would need to increase by nearly 500%[1]

Nothing wrong with pointing out issues/costs with nuclear, in fact it's good to point out the issues with nuclear so it can be properly weighed. I'm just trying to point out issues/costs of only using renewables, so we can weigh those as well.
> Nuclear being too expensive is the main point of this article. That seems upsetting to a lot of nuclear proponents. But I don't see a lot of arguments to counter that core point.
I think your missing the point. If you ran your entire grid on just solar and wind, no nuclear, or coal or natural gas peaker plants, you'll find that wind and solar is no longer cheap, and is much less resilient to exceptional circumstances.
> I don't get your argument about mining.
My point about mining is, our current course to fighting climate change relies entirely on mining, were making the switch from the Oil and Gas industry to the Mining industry for our energy and transportation markets. This change is going to have huge impacts on the world, mines are quite capable polluters of the local environment, setting up mines in developed countries can take a decade or more, which is the same problem nuclear plants face. Mining is also quite controversial for many good reasons, so there is significant push back from locals and environmental groups whenever and wherever a mine is proposed. All of this means a huge portion on mining takes places in countries with lax environmental and or human rights standards, which just exacerbates the problems.

If we forgo nuclear power the only other currently viable carbon free, stable, energy source is hydro power, which has huge environmental costs and immense public resentment/push back. For example look at the James bay hydro project[1]. 11,500 km2 of land flooded, intense protest from the Cree and other first nations as well as conservation groups, increases in mercury levels in fish populations, etc. Expanding hydro power enough to handle base load energy use is unlikely, due to the above costs and push back.
So if we can't expand hydro or nuclear then we have to go all in on wind and solar plus grid storage. We could use pumped hydro but that brings about many of the same costs/problems as hydro power. That leaves us with over building wind and solar, and adding huge amounts of transmission lines and batteries to account for the variability. Add in the switch from ICE cars to electric and the amount of new metals needed is going to be immense.
I've also noticed that every time a new transmission line or mine is purposed in the United States their is immense push back from environmental and conservation groups, and from the public as a whole. For examples of this look at the fight over adding new transmissions lines in southern Wisconsin[2] or the intense opposition to mining the Duluth complex[3] in northern Minnesota[4]. The Duluth complex is the largest untapped copper and nickel resource in the world and Polymet has been trying to get permits for well over a decade to mine. Copper and nickel are greatly needed for renewable energy and batteries, and it could still be another 4 or 5 years if it ever happens.
Not using nuclear energy is just going to massively exacerbate the transmission line and mining problems as well as increase the prices of renewable energy. Wind and solar is "cheap" because we don't factor in the added transmission lines, and natural gas peaker planets needed to currently make it happen. Also many of the groups pushing for wind and solar + batteries also happen to be against adding additional mines and transmission lines required to make it happen, and honestly you cant really blame them, mines can pollute local water supplies and transmission lines are ugly.
All and all a balanced approach is probably the cheapest and most viable path forward, solar, wind, hydro, nuclear, grid storage all working together on the grid.

It's not 1000 5MW plants vs 1 5GW plant, each SMR plant would have dozens of smaller cores. Most of the plans I see are in the 300MW - 1100MW range.
> Everyone agrees. But our goal with electricity isn't to make plants, it's to make watt-hours of electricity.
If the goal is to create carbon free electricity then making as many carbon free power plants is exactly how you'd get more watt-hours.
If you said something like "mass manufacturing wont make them cheap enough to be economical", that seems believable, but I'm not sure how you can blanket declare it wont make them any cheaper.
But for me the biggest issue is, if fighting climate change is so important, why wouldn't we try everything possible? Why do so many people insist on only renewables?
forecast.weather.gov doesn't show longer than 7 day forecasts because forecasts beyond 7 days are not very accurate[1]. So why show something that has a 50% chance of being wrong?
The majority of the data available to download is superfluous to most people hence why only a subset is shown on any weather app or website including forecast.weather.gov or Accuweather or whatever.
> It’s reasonable to separate providing data to providing data to the public
The NWS actually does provide visualizations for most of their data, and at this point I feel you don't know much about weather data/forecasting and are just looking to argue online. I provided a bunch of links below that allow curious people to look through American model data without having to use a company or having to program their own software. This list doesn't even include free to use apps/sites made by companies. American weather data is easy to access and view for free, Where as European model data is harder to access because you have to pay for it.

Yeah probably true, I didn't post a source because I thought it was common knowledge which in retrospect I'm not sure why I thought that.
And I'm glad you enjoyed the links, when I first started looking into the raw NOAA data and PRISM[1] data it took a bit to figure out what to do with it. But I've found the GDAL library helpful for parsing various weather data formats, and there are a lot of them[2].

So you admit that forecast.weather.gov is usable to the general public, but because it "doesn't maximize views" its some how invalidated? You said above that the public shouldn't need to use an intermediary to get a weather forecast and that's exactly what forecast.weather.gov is. And not only that but its faster and better than the for profit apps such as Accuweather, Weather.com, Weather Underground, etc.
> This isn’t some major expense, even 3% of their budget spent on communicating with the general public would easily cover several clean apps etc. Instead, it’s clear their largely a giant subsidy for private profit. Other government agencies charge for this kind of large scale data access by private companies to lower costs to taxpayers by removing subsidies.
3% of a multi billion dollar budget is a lot of money also why would they waste money on a "several clean apps" as you put it when they already have a working weather forecasting app and that money could be used to address issues like the bandwidth one described in the article above, or updating weather models? It sounds like you just want a fancy new app even though they already have a working one.
Huh? Did you even look at the links I provided above? They are literally what your talking about. One is a free government run website that any person can use to get a weather forecast, the other is a free government run website where any person can download raw weather data and use any way they like. So no intermediates or companies required.
And if your not able to use the raw data go to the NWS site which displays it in human friendly form: https://www.weather.gov/
Although I agree I like NWS way more than Accuweather or weather.com, etc, and I would be sad if NWS were forced to take it down.

Edit: Also, one of the main reasons vaccines were able to get through trials so quickly is precisely because countries like the United States, Brazil, the UK, etc did so poorly handling the pandemic. Doing phase 3 drug trials in a country that successfully dealt with SARS-COV-2 such as Australia would take significantly longer.
