@HALLish-jl5mo You cannot predict grid demand 20 years out, and maintenance is difficult to judge more than a year into the future, not to mention most nuclear reactors needs several hours to change their output, and only in emergencies can they dramatically lower it, due to the risks involved (damaging parts of the plant, risking increased service costs). Demand usually follows the weather to an extent, so you are also at the whim of the weather with any grid.
I have worked with wind turbines and had to deal with wind limits and clouds etc. limiting my work. I can confidently say that they can predict it with a precision of about 90% 3 days out and 70-80% up to a week in advance, and mind you as the date comes closer the accuracy increases, so last minute changes to prepare storage or get standby plants ready is possible, there will always be 3 days notice minimum, usually 7 days.
A nuclear reactor in itself cannot shut down it's output as quickly as a wind turbine can, I have shut down hundreds of turbines manually, it takes about 5-15 seconds to disconnect from the grid from the time I start turning the switches and pushing the buttons, hence why a wind farm can go from full production to zero in a matter of fractions of a minute if the grid is saturated, and they can start up in a couple minutes once the demand increases.
What we need anyways is storage, as we are not burning simple carbon or hydrocarbons, we can't adjust the output on a second or millisecond basis.
I really hope some giant battery storage systems comes online soon, and some giant thermal storage for district heating (like in my city, we have the second largest thermal storage in the world), industrial heating and in the future even thermal storage for seasonal electric storage (at the penalty of more losses due to thermal to electric conversion).

Running out of charge? You can always charge at home, so it is not an issue unless you live in an appartment building with no chargers at the parking lots.
The maintenance on solar is ridiculously low, and they do in fact live their full livespans, I do not know where that came from?
Wind turbines last a long time, I have personally visited some that are 17 years old and look well (drone inspection work, so I got full coverage)
Gasoline and Ethanol are incredibly inefficient, you waste more than 80% of the energy while converting it to mechanical work, and even more when including the extraction costs, refining costs and transport. Barely 10% of the energy contained and used to make it is delivered to the wheels.
Not to mention, oil will keep getting more expensive as cheap sourves dwindle, soon only dictatorships will have oil for you, unless you want to buy expensive oil.
EVs, Solar, Wind, Geothermal, heat pumps and energy storage is the future. Not fossil fuels.

And how much mining do you think it takes to produce the 7,000 to 10,000 gallons of fossil fuels needed for a ICE car?
The metals in batteries and the drive train in EVs are recyclable to 95-99%, meaning once the batteries are in the economy circulating, very little will have to be mined when the market is saturared.
Renewables are not the issue here, the issue is electric grid planning, in Germany they say "things have been cost cut until they crumble", so Germany js hardly a good example of what every transition will be like! It is a cationairy talenof what happens when you FORCE the transition to be cost constrained to an extreme, OFC there will be issues if you do that.
Nuclear is good and needed, BUT, it is slow to build and extremly expensive, it should be built and planned carefully. What we need is more fudning for energy storage, and a stricter control on volatile market prices of electricity, the speculative nature is hurting the economy for the benefit of a few rich companies who can sit on their hands and not fix the issues.
We do not strictly need fossil fuels, not in infrastructure, not in mining or in factories. We have the tech already, we just need to give insentices and penalites to push them to change. Corporations do not care, they are ONLY driven by money.
