When can we get some of those EVs and stop pretending that Tesla is a legitimate automobile company?
The sun is the biggest source of Energy on Earth. There’s no point trying to find an alternative energy source, because even if it existed, it would probably be much more expensive than getting energy directly from the sun.
and since all energy comes from the sun anyways, accessing it in the most direct way possible is obviously both most efficient and also least complicated. and that is why we have photoelectric machines, aka. PV panels.
Idk man. Cloud and air efficiency seems higher, even with the added propeler and magnetism step in there. Then again lost panel energy goes into air.
The growth of atmospheric CO2 is still accelerating. There has been zero evidence that this has changed.
Yes, renewables. But for every solar panel installed, our civilization’s lust for energy means that most of that added solar power is consumed without any appreciable commensurate decline in fossil fuel consumption.
Wondering if you read the linked article which presents evidence that this has changed?
Yes, the atmospheric CO2 is still rising due to emissions from previous decades.
The decline mentioned in the title is the current emmisions. The article goes on to explain it like this:
Locally, Europe and America have lowered their emmisions in the recent years, but global emmisions have still rised due to China emitting even more.
This June however, China’s emmisions have also decreased, so it might be a sign of a peak being reached.
Energy consumption is still increasing, but renewable sources provide enough for that, and it’s economical the best option, so the rising demand does not cause more emmisions.
Personally, I’m afraid it is too soon to tell. I also wonder where all the drilled oil and mined coal goes, because if there is an actual decline in fossil fuel usage, we’d be hearing from the oil companies and experience lower gas prices etc. Any fossil that is mined or pumped up is going to get burned, so I’d really like to see a decline in fossil extractions before celebrating.
Also, in order to address the atmospheric CO2 levels, we need something entirely different. Forests and CO2 capture etc., which have a long way to go still.

Tell me you don’t understand atmospheric CO2 without saying you don’t understand it.
Atmospheric CO2 represents the immediate, real-time, zero-delay composition of the atmosphere. As in, the current value is what currently exists.
And an acceleration curve in that value means that CO2 production is still increasing. if the curve is curving up, more CO2 is being released today than had been released yesterday.

Once that curve points downwards over more than a year or so, then I will become cautiously optimistic. Until then, I will not submit myself to counterproductive hopium.
Shout out to every “EVs are bad actually” person for being a dumbass who can’t sort out their priorities.
No, EVs in general aren’t a bad idea. But, to my knowledge, they have a lot of problems that no one is even getting close to solving on a global basis. There’s recycling of and mining for components, preferably in a sustainable way and without child workers. Also, EVs are still expensive as fuck compared to ICE vehicles, especially on the used market. And if you’re buying used, then the battery doesn’t even have full capacity anymore. And even IF you can get it switched by a mechanic (if you can even find one willing to do that), that is just even more money you have to spend upfront.
Granted, most of that might change over time, but for most people atm it’s just not feasible to buy an EV.
