Renewables Soar, But Fossil Fuels Continue To Rise as Global Electricity Demand Hits Record Levels (energyinst.org) 37
In a year when average air temperatures consistently breached the 1.5C warming threshold, global COâ-equivalent emissions from energy rose by 1%, marking yet another record, the fourth in as many years. From a report: Wind and solar energy alone expanded by an impressive 16% in 2024, nine times faster than total energy demand. Yet this growth did not fully counterbalance rising demand elsewhere, with total fossil fuel use growing by just over 1%, highlighting a transition defined as much by disorder as by progress.
Crude oil demand in OECD countries remained flat, following a slight decline in the previous year. In contrast, non-OECD countries, where much of the world's energy demand growth is concentrated and fossil fuels continue to play a dominant role, saw oil demand rise by 1%. Notably, Chinese crude oil demand fell in 2024 by 1.2%, indicating that 2023 may have reached a peak. Elsewhere, global natural gas demand rebounded, rising by 2.5% as gas markets rebalanced after the 2023 slump. India's demand for coal rose 4% in 2024 and now equals that of the CIS, Southern and Central America, North America, and Europe combined.

Fission on a large scale is too risky. During a big war many of those nuke plants will get either bombed into radioactive dust/rivers or neglected, triggering a nuclear winter, killing off 95% of humanity.
It's not the full solution. I hope fusion pan's out. Stellerators have Yuuuuge potential on paper. (I expect computing power will eventually make Tokomaks obsolete compared to stellerators.)

"Nuclear Power will solve the climate crisis, and it doesn't need a breakthrough or a TED talk, all it needs is a building permit" - Sabine Hossenfelder.
How does that deserve getting moderated as trolling?
I've seen people do the math and nuclear power with low cost thermal or pumped hydro storage could provide all the energy we need while taking our CO2 emissions so close to zero that it could be lost in a rounding error. It should be clear that's hardly likely to happen. As competitive nuclear fission is on costs compared to fossil fuels there's plenty of places on Earth were hydro, geothermal, onshore wind, and a little bit of natural gas would bring lo

You Because nothing gets built with only a building permit. The comment is just an underhanded punch using the largely discredited notion that regulation is what's preventing nuclear power plants from being built in the United States. I don't know if that is why it was moderated, but it is certainly one reason it should be.

Of course there's more to the process than just a permit but there will be no new nuclear power plants so long as governments refuse to issue permits. There's been bans on new nuclear in the USA from state governments in California, Illinois, and New York. There may be others but these are likely the most notable as these states have relatively large populations and therefore the most demand for energy in the USA, and is likely comparable to the energy demand of many nations. I recall Illinois and New Yo

A different outcome than overtaking both nuclear and coal in the USA [eia.gov]? Are you trolling, because why would anybody want that?
Re: (Score:2)
We'd want a different outcome because the increasing reliance on renewable energy and "peaker" natural gas to cover for the inherent intermittency of renewable energy means higher prices. Because the single cycle turbines used for "peaker" power are 1/3rd as efficient as combined cycle "base load" combined cycle we can see the same amount of natural gas fuel burned with renewable energy as without. That means not only higher costs for energy but no real reductions in CO2 emissions to show for it. We'd ge

Well, the world largely forgot how to build nuclear power plants since new construction came to a near stop for decades. Most of the people with the required experience are retired, senile, or dead.
Which means actually building nuclear power plants requires recreating an industry that didn't work very well the first time around. We are talking decades before it will scale. You can do a math model for how long it will take with a bunch of assumptions. Many of which will turn out to be optimistic because starting with pessimistic ones brings you to the obvious conclusion that it will take too long, cost too much and is too uncertain of success. Especially when there are viable alternatives immediately a

I so wish this nonsense would die.
The hottest part of the day isn't noon, it is about 4:00 PM when solar power output is beginning to wane. The outdoor temperature is starting to decline as sunset gets closer but that can still be many hours until the outdoor temperature is low enough that air conditioning needs has reached it's minimum in the time just before the sun rises again.

What I see as a better plan is to leave the expensive rooftop solar PV out of this and just go with a Tesla Powerwall
I didn't know Tesla Powerwalls were a budget item, I thought they were pretty pricey. Especially compared to a few solar panels.
Your overall point that we are going to need storage to make full use of solar is correct. Solar does not peak at the hottest part of the day. So if we have enough solar to handle air conditioning, we will have excess solar at other times. We need to be able to store it to dispatch when needed.

I can always tell someone with a lot of spare money / privilege because they talk about building new this, or wanting to ignore how we're meeting base load. They're also the people that assume people will buy new electric cars, or that delivery services will all be like the Amazon Rivian or USPS duckbill, brand spanking new.

Petroleum oil is a fossil fuel because the word "fossil" is derived from a word meaning "dug up". Something is a fossil by being pulled from the Earth. The meaning of the word "fossil" has evolved some over time but the original meaning of something being dug up never really went away. For something to be a fossil doesn't necessarily mean it has a biological origin, it can mean something with an origin in the Earth. There's evidence that plenty of fossil fuels do not have a biologic origin: https://en. [wikipedia.org]
