That's wildly inefficient at scale (and that's if it can be done reliably). Check my numbers here—should be correct but I'd appreciate pushback—estimating 50% of annual U.S. usage in panels vs nuclear plants: https://imgur.com/a/zeHo21R . Even if we want 50% of our power nationwide to come from solar power, based on your 60 acre model that's still 6,429 of these installations or 385,753 acres (and that's with a gener…

First 385,753 acres is trivial in the US. The federal government for example manages 640,000,000 acres in the US, it’s a big freaking country. We where doing above ground nuclear testing because we just had that much unused space. As to output per day real world capacity factors for grid solar vary by location but tend to ~30% here’s a 29.7%. https://en.wikipedia.org/wiki/Mount_Signal_Solar So if a 400W panel average…

> By comparison at 2.9kWh per day panel * 2000 * 640 = 3,712,000 kWh per day from solar.

How is being less efficient by ~10,000,000 kWh per day preferred? That's a significant difference in output. You seem fixated on price and are ignoring the reality that solar panels inconsistently generate that amount of energy whereas nuclear is more stable. If climate change is literally going to destroy the world, then cost should be of less concern than "can it give us the power we need while reducing emissions?"

> Try and hit 100% with nuclear and your stuck with sub 50% capacity factors or your need a lot of grid storage both of which dramatically increases the price.

Can you share what led you to this 50% capacity number?

First intermittency is just a cost of battery question, because cost of one type or another is the only meaningful metric. Hell if land use bothers you we can put panels on rooftops, parking lots, between highways etc. It’s wasteful but plenty of people are doing it.

Also, 13,968,000 kWh per day * 70% capacity factor = 9,777,600 kWh so solar only needs 3x to 4x the land. Except, nuclear reactors need land near large bodies of water making that land far more valuable. So because you can’t put a nuclear reactor on the ultra cheap land viable for solar panels Nuclear actually ends up with higher land costs.

Germany. Seriously, I don't know of any other country with such a combination of industry, education, social security, and absence of natural disasters as well as poisonous animals.

With relatively subdued salary levels compared to tax and cost of living, I’m not sure Germany is the best answer.

Isn't it among the best in the EU?

It's not a matter of technical feasibility (i.e., you could do it, but is it the best. most stable way), it's what is the goal. All of those batteries require fossil fuels to be produced, as do the solar panels. Favoring the model where you have to produce more (meaning more fossil fuels) is the antithesis to the greater point.

The more efficient option—even if more expensive—should be preferred. You may end up getting similar results, but the overall impact of trying to make solar panels play catch-up is more destructive in the long run. And they don't even catch up. By your own math, even at 70% capacity a reactor is 3x as powerful.

And re: the water requirements, those would also be a factor in hydroelectric so it's a moot point (assuming you see hydroelectric as a supplemental form of power to solar).

I've yet to do research into inputs of manufacturing a plant vs solar/wind/etc. so can't give specifics but just in the abstract what you've described sounds more wasteful (and that's if it can be done—there is far less ambiguity with the nuclear option).

The only necessary CO2 release from batteries is based on the current state of our global economy. Reduction in the amount fossil fuels used in the grid and mining equipment directly reduces the use of fossil fuels manufacturing batteries and solar panels all the way down to zero.

As part of being massively more expensive, Nuclear actually involves significantly more indirect fossil fuel usage due to those costs. For example all a nuclear power plants requires onsite fossil fuel generators which need to be run regularly: http://aa-powersystems.com/wp-content/uploads/3061871_OE_Bro... Yet those generators are left off of assessments of CO2 releases associated with nuclear power plants. Similarly the centrifuges reacquired to manufacture nuclear fuel require vast amounts of electricity to manufacture and run. The nameplate generation from Nuclear further ignores those ongoing energy costs.

If Canada started producing 10x per person it would be the worlds second largest emitter. So yeah, it would matter. Pretending this is exclusively China’s problem when the rest of the world produces 3/4 of global emissions and a significant percentage of China’s emissions are a result of demand from the West, is simply nonsensical. We will not get out of this by focusing on spinning stats or trying to focus attention…

There is an inconvenient truth we all avoid when we throw out climate change. There is nothing you can do to stop climate change. If you stopped all Canadians from producing any greenhouse gases the wildfires will continue and no one will have noticed. When two countries are producing the vast majority you are at their mercy. If Canada wants to bully, bribe or shame a country into submission it has to get bigger and…

Here come the 'China bad' bots without a hint of self awareness about the emissions/capita of almost every single western country, let alone the disasters like Gulf of Mexico on fucking fire right now.

The comments I usually reply to are doing the exact same thing - jingoistic, borderline fascist comments but from the other side (which happens to be what this website's general population is aligned with).

At this point I don't really care that this forum remains an echo chamber - so you won't see me post these comments anymore.

And yet we'll continue to treat climate change as an inconvenience that can be addressed in 20 years, when - to quote Alex Steffen - we're not yet ready for what's already happened. https://alexsteffen.substack.com/p/were-not-yet-ready-for-wh...

Meanwhile some EU nations are opposing the classification of nuclear energy as green for ESG purposes.. https://www.reuters.com/business/energy/germany-four-others-...

Spain, Denmark, Austria, Luxemburg.

Spain/Germany: https://www.siemensgamesa.com/en-int

Denmark: Much Wind and other 'greenery'

Austria: Water, never did nukes, has one complete NPP without the hot-stuff as museeum now.

Luxemburg: yawn?

This is even more hilarious: Germany oppose nuclear, which is the greenest energy source in terme of emissions, but managed to get funding to use "green" gas: https://ec.europa.eu/commission/presscorner/detail/en/ip_21_...

It’s fine. They are going to get vegan gas from Greenpeace. I wish I were joking.

You mean like this?
