bullet points from the article:
- Renewables’ share of the global power generation mix is forecast to rise from 29 percent in 2022 to 35 percent in 2025.
- China will account for more than 45 percent of the growth in renewables, followed by the European Union with 15 percent and the United States with 6 percent.
- Nuclear output will also increase as France completes scheduled maintenance on its nuclear fleet, while new plants come online in Asia.
- At the same time, global electricity generation from both natural gas and coal is expected to remain flat over the next three years.
- Still, while coal generation is expected to decline in Europe and the Americas, growth in Asia could partially offset this drop.
​
Two caveats mentioned:
If China's economy bounces back, they could use more coal.
The other is bottlenecks like Germany reactivating coal power due to the war in Ukrain.

This is great news. I am constantly surprised at how fast and accepted clean energy is. I don't know of a single nation that opposes it. And everyone seems to race on adoption.
I expect big things by 2050.
Go, humans, go!

You are aware that Donald Trump was President of the US only 2 1/2 years ago right?
I am happy for the success, however I am still very mindful of conservative and capitalist (Oil & legacy auto) opposition.
The economics are clear, but there are plenty of people and organizations that are doing a lot to slow the progress.

Sure, but as a general view, it seems clean energy is getting support overall. It was only a few decades that some nations wouldn't even have any plans for clean energy at all. There will always be some groups with business incentive to go another direction, but it wouldn't, for example, be the stance o f the US government to say 'the heck with clear energy!' over the span of a decade.
It is my ignorance talking, but I was very pleasantly surprised that even China, India, and African countries are onboard. Maybe I shouldn't have been surprised. Maybe articles from decades ago made me doubt 'emerging global economies' would be in on this 'new green pipe dream'.
Exciting times we live in. Heck, I personally know an older neighbor that finally bought a sun-powered light for the front of their house and he can't stop being gobsmacked at the whole thing. "Free light?! No wires?!".
It hits differently just reading about something as opposed of trying it and seeing it for yourself.
Another guy said their next car they'll buy (in half a decade or so) will be electric. That was never thought of to some people just a few short years ago.
Things are happening and happening quickly. I am glad this is a global phenomena as well. Tech progress is becoming more and more ubiquitous. There was a time where the difference in tech between nations was generational. Now the majority of the planet has electricity and half have access to the internet. That is absolutely insane to me.
I talked to people that are now grandparents and some even still middle-aged that told me they remember growing up without electricity at all. Now they all have social media accounts and streaming Netflix shows. One lady showed me how her dishwasher 'talks' to her through her phone telling her it is time to empty the dishes.
That's wild. And all that is within one lifetime or less.

I was on two waiting lists for EV trucks but decided against it for now. I’m going to wait till they iron out the bugs and come down in price more. And every other week there seems to be a better cheaper battery technology coming down the pike so that makes me want to wait too.
Semifreak t1_j7z455j wrote
Yup, plus where you live still matters in these early stages (for charging).
I read one analyst that expect EVs to reach price parity with ICE in 2025 and the following year EVs would be cheaper than ICE cars.
Even if that prediction is off by a few years, that is still relatively soon.
Heck, NASA and others are experimenting with e-planes now! That's something I haven't even considered. But I guess if you have the density/weight of batteries right, planes can be an option.
Maybe in 100 years there will be no fossil powered vehicles or transport of any type. It is certainly not crazy to entertain such thought seeing what is possible today.
Man, I wish the show Tomorrows World was still on. Check out their episode predicting the future. They nailed it! And the future isn't just constrained to today, so some of the things that are slightly off (but we still have similar ideas to it today) might be possible in the coming years and decades.
Here's the episode for fun. I LOVE seeing old predictions about the future:

That was in 1989 predicting the home of 2020. Imagine what things will be like in another 40 years!

I put panels on my house in 2017 so what does who POTUS was at the time change about that. Not like it was criminalized.

Stop, no one is opposed to solar and wind just the lies told on how it will replace oil and gas all by itself anytime soon. Nuclear solar wind and hydro is the future in every state,

Wouldn’t we want to see these declining steeply to have much optimism for 2050?

The IEA has long history of greatly underestimating the adoption of renewables. To the point where I question if the Oil lobby influences their reports. Every single year they revise their estimates and they're always an underestimate. We are currently way above their best case predictions from 5 or 10 years ago. For some reason they always try to model the growth as a linear graph when it has clearly been following an S curve for quite some time now.
goodsam2 t1_j7vltou wrote
Today we are past their best scenarios in like 50 years. The report is honestly baffling. it's also been like that for a decade.

The article includes this quote.
>“For many years the IEA earned the reputation of vastly underestimating renewable energy growth,” he said, “so there might be a tendency to bend over backwards and err on the side of exuberant optimism.”
Did they give inflated electrons this time? The report itself says
>Our outlook for 2023 to 2025 shows that renewable power generation is set to increase more than all other sources combined, with an annualised growth of over 9%.
I get confused at that point not knowing if they mean any of three things.
9% growth in energy output annually
9% growth of installation of equipment compared to the previous year
9% growth of equipment from the previous accumulated
Anyway, hope they have vastly underestimated as usual. Every time I look into their assumptions they did a significant bias toward minimal growth.
Yesterday I looked at their projections for our mining and minerals needs for example and they were so pessimistic and already demonstrably wrong.
Semifreak t1_j7veuip wrote
That's just 3 years. I'm wondering about what will happen in 30 years. And even 30 years is not really that long.
The speed of progress is astonishing. So much will change and happen in 2050 it is ridiculous...ridiculously awesome, that is!

I'm hoping we get inexpensive A SMB reactors, or supercritical geothermal borehole tech going.

Now we're talking!
Maybe even break the fusion power challenges. Re0designing much more efficient experimental tools for research from medicine to space studies. Way better batteries, too.
The sky's the limit!
Rofel_Wodring t1_j7zlah5 wrote
Expect commercially viable fusion at the end of this decade. Maybe not an actual plant that provides your home power (though there will definitely be viable near-term plans to do so) but unless I've been the wrongest I've been about anything in my life this decade will be the last decade of that stupid nuclear fusion joke.
Semifreak t1_j818tqo wrote
Things are certainly looking up. MIT will run a test in 2025 with their 'mini' sized reactor (tiny magnets). ITER in 2035. And there is a third company using plasma instead of magnets I read about but I forget when their test run will be.
Of course it will be decades till actual homes run on actual fusion plants power after a successful 'proof of concept' from at least ITER or maybe MIT, but at least we can know for sure if fusion is doable or not in just a decade or so.
Also, 'decades' is not a long time, really. Nuclear power plants were first suggested in 1941 and the first commercial one started in 1957. I think even skeptics don't have a problem imagining fusion power would be real by 2100. The question is how soon can we get it working- if we can, just to keep an open mind. After all, everything is vaporware till it happens.
Let's just hope governments can streamline the paperwork and fix the crazy, crazy, 'over head' and 'manager' costs to speed things up.There is a SINGLE public toilet in San Fran that is costing 1.7 million USD to build. California's high speed rail costs as much as the International Space Station (which costs its weight in gold due to the cost of delivering something to space).
Today, building a nuclear power plant to take up to 7 years or more and that is because all of the red tapes and permits...
But maybe the public will get excited for fusion once it is proven commercially feasible and pressure lawmakers to get it rolled out faster. After all, it seems the talk about favoring clean energy is growing by the year.

the IEA and any other energy outlook has historically always underestimated renewables, I would confidently bet you that by 2025 we'd be in a much better state than that
goodsam2 t1_j7vmqrq wrote
I mean growth stopped, renewables are cheaper than starting new plants.
Then renewables replace retiring Fossil fuel plants.
Then renewables accelerate retirement plans for fossil fuels.
Also natural gas and renewables work well together in a brief period because if the sun and wind stop you can add natural gas easily.
DGrey10 t1_j7uyurj wrote
The problem is that total use is increasing. So flat gas and coal absolute use is a reduction in the percent of the electric generation mix. But it means the C emissions haven't changed, they just aren't getting worse.
dontpet t1_j7vt9uc wrote
This is what a tipping point looks like at the top. If renewables continue in their growth pattern we will be pushing down fossil fuel growth very soon if not already.

Three years is pretty short though. For Germany, I expect the energy consumption to rise due to heat pumps replacing gas /oil heating and electric cars replacing ice engines.
I don't think we can increase renewable energy generation fast enough to cover those as well as the existing generation in the next few years, but it's still a overall emissions reduction.
Rofel_Wodring t1_j7zlts4 wrote
Electricity consumption, yes. Energy consumption?
I think people would be appalled to learn how much energy gets wasted on things like legacy HVAC and cheap housing. Let me put it this way: energy efficiently management is sort of a scam in the area I live, but the legacy HVAC is so wasteful and suboptimized that even a charlatan can bring results.

Personally I don't think any level of just emissions reduction will dodge catostrophic climate change at this point. It's just not plausible that at this level of rapid change, warming and ice melt that reducing emissions by 2050 or such would be really anywhere near enough.
At best you have to pull CO2 out of the atmosphere and at worst you will have to employ some level of solar blocking to reduce heat build-up. It's a long term Co2 build-up and the CO2 doesn't go away quickly, so emissions reductions are just bets that we can limit warming. They aren't guarantees of anything and that's kind of the problem. The upside is solar blocking would lower heat immediately so it would be a good way to combat the core problem, which is heat, vs trying to only attack it from the insulating gas angle.
To me ice melt and changing climate happening well before models predicted means it's already too late for just emissions reduction. You certain still need emissions reduction, but betting the planets future on such a passive plan with no proof our modeling is accurate enough to make such a bet AND when we have other options to limit warming just seems dumb.

Too late for what? It’s only too late if humanity stops working on the solve.
Is it going to get worse before it gets better? Yeah I’m with you there, it probably will.
So what can we do? Work harder at turning it around and not let up or just give up and die?
You think people are passively saying ‘well this one band aid is obviously enough, good job’ there are tons of sectors looking for ways to forestall disaster and we need all of the fixes in the toolbox.
Emission reduction is a requirement because you can’t clean up the mess if the hose is still spraying everywhere while you are trying to mop it up. There are also lots of ideas for cleaning up the mess as well which are all great, and we can work on all phases of the project at the same time!
It may take centuries to undo what we’ve done in the last 100 years but we are actually starting to believe we can turn things around, and with constant applied pressure to a large enough lever you can move the world.
But would you kindly get off the wrong side of the lever? It works better with us all pushing over here instead of undermining those who are attacking the problem from all sides.
