> Right now it looks like it's just adding more power on top of traditional carbon emitting sources.
Here is what the IEA observes on 2022:
>In a year marked by energy price shocks, rising inflation, and disruptions to traditional fuel trade flows, global growth in emissions was lower than feared, despite gas-to-coal switching in many countries. Increased deployment of clean energy technologies such as renewables, electric vehicles, and heat pumps helped prevent an additional 550 Mt in CO2 emissions. Industrial production curtailment, particularly in China and Europe, also averted additional emissions.
Or in other words: we are not "just" adding power on top of traditional carbon emitting sources. Rather, the deployment of low-carbon sources has reached a point, where we are very close to a balancing point at which those low-carbon additions cover the increment in global energy consumption completely.
More observations from the IEA:
>A strong expansion of renewables limited the rebound in coal power emissions. Renewables met 90% of last year’s global growth in electricity generation. Solar PV and wind generation each increased by around 275 TWh, a new annual record.
>China’s emissions were relatively flat in 2022, declining by 23 Mt or 0.2%.
>The European Union saw a 2.5% or 70 Mt reduction in CO2 emissions despite oil and gas market disruptions, hydro shortfalls due to drought, and numerous nuclear plants going offline.
>US emissions grew by 0.8% or 36 Mt. The buildings sector saw the highest emissions growth, driven by extreme temperatures. The main emissions reductions came from electricity and heat generation, thanks to unprecedented increases in solar PV and wind, as well as coal-to-gas switching. While many other countries reduced their natural gas use, the United States saw an increase of 89 Mt in CO2 emissions from gas, as it was called upon to meet peak electricity demand during summer heat waves.
>Emissions from Asia’s emerging market and developing economies, excluding China, grew more than those from any other region in 2022, increasing by 4.2% or 206 Mt CO2.

That's not my argument. Mine is clearly our current economic and government systems are failing to slow climate change. Technology wont save us from civilization collapse alone.
It will require drastic changes now. WW2 levels of international effort in a very short amount of time.
We already had issues with farming in a huge number of significant regions last year. If that continues we will end up seeing the largest famine in human history in a decade or two.
El nino is coming this summer and it'll supercharge the warming we already see.

As the war on drugs showed us, there’s a very wide gap between laws and their enforcement.

They’re a massive portion compare to a few years ago. What do you expect?

It’s a huge, long term investment. We’ve only seriously been doing this shit for about a decade.
Carbon emissions being high currently is obviously concerning, but it really doesn’t belong in a conversation about renewable power and I caution you against the conflation since deniers are liable to use it in bad faith. “Look! See! Doesn’t work! No better!”

This is solar road ways all over again.
What's wrong with taking a rest every 2-3 hours at a rest station and charging for 15-30 minutes? You wont fully charge but you dont need to fully charge.

It hasn't happened to any significant degree yet. The tiny fraction that do exist have historically been recycled for metals and low grade glass at a loss or landfilled.
Recycling supply chains are being built and most of the world now has recycling mandates where manufacturers or importers need to have a plan in place before sale. The glass can be used circularly, silver and bismuth/lead are reusable. The silicon is downcycled to steel alloying or similar industrial use. There has been lab scale amorphous PV built from only decomissioned monocrystalline PV -- it worked but has not been commercialised.

Not a CEO, but a senior manager at a cable company I worked for - we had a sales team of contract workers that were let go one night with no warning. The term he used to me was we were going to "gas them". Nothing like a nice holocaust metaphor.

Yes they can be recycled but it isn't done on a large scale yet because arent may panels that have reached end of life yet.

Gas needs gas to get to the gas station. Build wires to gas stations once and get electricity for years without gas or semis or trains or refineries that all cost money to run. Its simple really, fewer moving parts, less cost.

It's actually a really good idea. I think the best way to electrify the roads would be via overhead cables that the cars could connect to. Then, to further optimize things, we could combine cars together into one really long car. We could call this thing a "bus", give it a planned route with a bunch of stops for people to get on/off, and move a whole bunch of people that way.
But since everything's moving in a predictable path, we may as well replace the wheels with rails. We could even go crazy sci-fi and build a series of underground tunnels to get them out of everyone's way and make things a lot faster and safer. Let me know what you think of such a system. I think we should call it the Hyperbus.

None of that matters since emmisions literally hit record highs last year. So clearly we are failing.
The time for incremental changes was 2 decades ago. We can't afford to do this slowly anymore.
