The World Saw a Record 9.6% Growth In Renewables In 2022 (electrek.co) 133
By the end of 2022, global renewable generation capacity amounted to 3,372 gigawatts (GW), growing the stock of renewable power by 295 GW or 9.6%, according to the International Renewable Energy Agency (IRENA). Renewables produced an overwhelming 83% of all power capacity added last year. Electrek reports: Renewable Capacity Statistics 2023, released today by IRENA, shows that renewable energy continues to grow at record levels despite global uncertainties, confirming the downward trend of fossil fuels. While many countries increased their renewable capacity in 2022, the significant growth of renewables is concentrated in Asia, the US, and Europe. IRENA reports that almost half of all new capacity in 2022 was added in Asia, resulting in a total of 1.63 terawatts (TW) of renewable capacity by 2022. China was the largest contributor, adding 141 GW to Asia's new capacity.
Renewables in Europe and North America grew by 57.3 GW and 29.1 GW, respectively. Africa saw an increase of 2.7 GW, slightly above 2021. Oceania continued its double-digit growth with an expansion of 5.2 GW, and South America had a capacity expansion of 18.2 GW. The Middle East recorded its highest increase in renewables on record, with 3.2 GW of new capacity added in 2022, an increase of 12.8%. Although hydropower accounted for the largest share of the global total renewable generation capacity with 1,250 GW, solar and wind continued to dominate new generating capacity. Together, both technologies contributed 90% to the share of all new renewable capacity in 2022. Solar led with a 22% (191 GW) increase, followed by wind, which increased its generating capacity by 9% (75 GW).

As far as coal in the US, that is already down 60% for electricity, and the technology for steelmaking is shifting slowly way from it.

Can I see your numbers? The way I figure it, total worldwide primary energy usage is about 600 ExaJoules. Of course, if we move to electricity in transportation and industrial processes, the increased efficiency will bring that requirement down to about 400 Exajoules. 400 Exajoules per year works out to an average constant rate of about 12.68 TeraWatts So, if renewables are really up to 3.372 TeraWatts, they have about 9.3 TeraWatts to go. Even if it stays at just adding 300 GW per year, instead of increasing year after year, then they could theoretically reach full replacement in about 31 years. Now, that is longer than the replacement period, so the rate does need to increase, but it's doing so year after year. If it gets to a little over 600 GW per year, then complete replacement becomes basically inevitable.

I think the message is that building EVs that weighs 2tons is a bad idea itself. Is it better than building combustion-based cars? Maybe... It basically mainly depends on the battery size, and the number of kms you use it for. For instance, an EV with a 60kWh is better than a combustion engine car at ~65000 kms (source [ademe.fr]).
At the root of the problem is that when driving alone in a car (most home-work commutes are solo-drivers), 95% of the energy used is used to move the weight of the car.
If you take an electric bike for instance, 90% of the energy used is used to move the commuter.
And don't start with anecdotical situations "but I live in the country", "but I am a farmer", "but but but". Of course this solution is not for everyone, but most people (especially in Europe, and I guess even in US big cities) are less than 10-15kms away from their work.

It's not so much about construction costs, but about environmental impact, and in the context of the study, about CO2eq emissions.
To sum it up:
- an EV with a 22kWh battery is better CO2eq-wise after ~20k kms => works for a lot of city people, or people who already have 2 cars for instance
- an EV with a 60kWh battery is better CO2eq-wise after ~65k kms => it will break even, but people need to ask themselves if they really need that battery size. If not, you can build 3 EVs with the same material (battery I mean), so the overall impact is a lot less. Again, some people might need it, just not everyone, everywhere
- an EV with a 100kWh battery is better CO2eq-wise after ~100k kms => we start to reach a point where you will might need to replace/recycle the battery depending on your mileage/year. Many people like to switch cars after 100k kms, because they want the latest shiny stuff. Another good way to avoid CO2 emissions altogether is to use your stuff (car, smartphone, computer) longer.
So yeah, an EV is good. An EV with a small battery is better.

Sure, but environmental impact is a type of cost, just like monetary cost, which is amortized over the average longevity of a vehicle.
Whether or how many times it gets sold is immaterial. Nobody takes a still-working car to the junkyard after 100k km (62k miles). (Or if they are, fixing that would be a super-easy way to reduce the amortized pollution of car construction.)
Toyota has taken this argument to somewhat of an extreme by arguing that we should not be building EV's until the battery supply is large enough for all cars - instead, you fractionally electrify a larger number of hybrids, which increases utilization of the batteries that are available. Mathematically this does make sense. If you have only enough batteries for 200 miles of range, you can either make 1 EV with 200 mile range and 9 gas cars, or 10 hybrids with 20 miles of electric range each. The 10 hybrids will fully utilize their batteries regularly, whereas most of the batteries in the single 200 mile EV are just dead weight on most days.

It is a bit more complicated than that.
First there is the season distribution: 2/3 of the energy produced by solar panels is produced during spring-summer (because longer days and better light conditions, i.e., less clouds). Which leaves only 1/3 for autumn/winter. Here is a source [thesolarnerd.com], you can find plenty others.
Guess what: we need more energy in winter, because this is when people turn their heater on. And as we push more and more for heat pumps, which is a good thing as it can be powered without burning fossil fuels, we need more and more electricity in winter. As we transition to EV, it will also lead to more electricity needed in winter for that: for instance, I am using my bike a lot to commute in spring/summer/even autumn, but I use my EV more in winter because of the weather conditions.
Secondly, there is the time of day distribution: in winter there are usually two power spikes (here is the data for France for instance [rte-france.com], I don't really expect it to be different in most modern countries as it is based on pretty standard human behavior). One between 6-9am, because people wake up, heat their house, turn their TV/other stuff on, etc... And then another one between 6-9pm, when people go home, heat their house again, turn on their appliances, etc... At those hours, solar panel produce next to nothing.
Of course, that problem (the one about time of day distribution) could be slightly fixed by adding storage capacity, but your post didn't mention that.
Thus the answer by a past president from France regarding solar panels, during a series of questions by the National Assembly around the loss of energy generation independance: "the problem with solar panels is that they produce a lot of electricity when you don't need it".

True enough, however peak energy demand is in Winter for most, if not all, of northern hemisphere. So generally speaking (at least for 87% of the population by raw estimates), winter is still gonna be a problem.
If you wanted to refute my point though, you could have linked this study [carbonbrief.org] from 2017, saying that peak demand might shift to summer for some European countries. However, the devil is in the details: in that scenario, the peak would happen in summer (because of climate change), but we would still need roughly the same amount of energy in winter, because those winters would be as cold, if not with colder episodes. So at that point, solar panels would become a way to smooth the load in summer, but still not provide a reliable solution for winters.

I can also provide a link. [eia.gov] Here's a quote from that which gives a more general perspective than your link, at least for the US:
Total U.S. hourly electricity load is generally highest in the summer months when demand peaks in the afternoon as households and businesses are using air conditioning on hot days. During the winter months, hourly electricity load is less variable but peaks in both the morning and the evening.
Note, overall for the US, electricity usage peaks in the summer, and that peak is in the afternoon when solar is available. The double daily peak is in the winter, but is lower than the summer peak. So even though solar won't contribute that much to the daily peak requirements in the winter, it's still useful for trimming the yearly peaks.
Now I'm not saying that solar is the economical solution to provide all the power needed, since you would have to greatly overprovision solar and add a lot of storage, but it can contribute to the overall goal of getting off of fossil fuels.

Considering how prices are set in the electricity market, if this is capacity, given the current price schemes, I'd expect that growth to be actually higher.

It all depends on the type of renewable energy, where it is located, and what it is for.
Offshore wind is now exceeding 50% capacity factor, rivalling nuclear in Europe.
Some renewable energy is also not supposed to have a high capacity factor. They are currently looking at building new hydro in Scotland, designed to time-shift very large amounts of energy via pumped storage. In other words it's only supposed to work half the time.

50% capacity nuclear capacity factor is for France because they have low demand in the summer. Most others run at around 70-80%.
Solar is around 15-20% capacity factor and onshore wind 25%. I can't find the European share of offshore vs onshore but in Germany and France the vast majority is onshore, for example ~8 vs 56GW: https://www.cleanenergywire.or... [cleanenergywire.org]

I thought France was keeping the lights on in Germany all summer, because the Germans foolishly tried to replace coal and nuclear with renewables. Guess not.
The actual reason for the abysmal capacity factor is that French plants are old and need a lot of maintenance. Even excluding them, nuclear capacity factor in Europe is only about 75%. It's just not very reliable.

That too but you can see the French use massively less energy during the summers, and not just this one. Compare 2021 or something: https://www.rte-france.com/en/... [rte-france.com]
All European plants are very old, but 75% includes refueling, maintenance and and ramping down with demand. Seems reasonably reliable.

It is true that Germany uses bit more coal and exported a lot to compensate for the failure of the nuclear industry in France, but one has to put this into perspective: In 2022 Germany produces 213 TWh from fossil fuels vs 243 TWh from renewables. So renewables was more. And production from fossil fuels is also was not nearly on the same level as in the past (e.g. 259 TWh in 2018, 275 TWh in 2017, 292 TWh in 2026...).

Reduction of CO2 emissions linked to fossil fuels burning in Germany can be directly linked to a decline of their heavy industries (shutdown because of high energy prices).

Yes yes, none of it was to compensate for a lack of baseload since they for once couldn't rely on France imports.

Except we are not talking about GDP here, which can be inflated through a number of way.
We are talking about how high energy prices and material shortages, which hampered industrial production and construction [destatis.de], caused a reduction of CO2 emissions in Germany in 2022 (high prices pushed down emissions from industry and construction [cleanenergywire.org]).
From an economic standpoint, and a long-term vision though, industries facing shortages and being forced to close down is not a good thing. It only means you are decreasing your CO2 emissions by destroying jobs, and losing parts of you industry. Same thing as being happy about the fact that when you are dead, you are not emitting CO2 anymore...
If you talk with actual germans working in those industries, or in construction, they are actually worried and their future doesn't look so bright.
To sum it up, it's too bad that the decline of Germany CO2 emissions had to be at the expense of their industry and construction sector. Wouldn't it be wonderful if we had a source of low-carbon electricity, that we know of since ~1960, and which could provide the kind of baseload needed by the industry sector? I know, fairy tales.
Also in the past, Germany always did export more electricity to France than vice versa. I checked all years going back to 2015.
You mean, except in 2020, when it imported 10tWh from France, and 2021 when it imported ~5tWh [reuters.com] (here is another source [fraunhofer.de]) ? Saying that you checked is not enough, you need to actually do it, and not just come up with fake numbers.
That should make people put into perspective the assertions you like to throw around, not based on any actual facts.

And to think they could have invested in both renewables AND nuclear, so that they would have been able to only emit ~40gCO2eq/kWh like in France, instead of the ~450gCO2eq/kWh like they do now with "all" their renewable capacity.
It is sad to see that Germany is one of the biggest CO2 emitter in Europe, despite its efforts since 20-30 years. So much CO2 emissions could have been avoided if they had gone the science path, instead of the philosophical one.

It's the electricity economy (Score:2)
I don't know about your country, in mine, the price for electricity is set by the most expensive power plant that is used. That means that if you have 4 power plants and need the power of 3, the 3 cheapest ones get to deliver, the fourth does not, but the price that all the 3 get is set by the most expensive one of those three.
Now let's take a look at the price of power generation. And especially what changed last year.
Gas used to be a fairly cheap power provider. That changed dramatically last year as probably everyone noticed. Gas jumped from one of the cheapest forms of power to the most expensive one. And took that spot from exactly these contenders: Renewables.
Solar and wind are clean and nice and all, but they are one thing not: Cheap to produce. And they also have another not so great disadvantage for a producer: You can't just switch that plant on and off however you want. They are great basic load providers but very poor peak load providers. In that pricing model, though, they would have been the peak providers, because at times of low consumption, they'd be pushed out the top end of the power delivery system, being too expensive for their electricity to be required. But you can only produce power with wind if it's blowing and sun if it's shining, it's not like you can switch wind and sun on and off as you please.
That changed big time with gas prices hitting the ceiling last year. Suddenly, they were basic providers. With gas being the peak load. Which is actually not that bad at all, gas turbines can very easily be throttled as demand dictates. Not only that, but suddenly you got more money for your wind power than you minimally needed to run them, so suddenly building those wind power plants because interesting even without subsidies.
