Whoever wrote that article is playing fast and loose with the definition of exponential.
Here’s the actual data of global electricity source on a log scale for the past ~15 years
Notice that the line for both wind and solar is inflecting to the right. If it was exponential it would be straight.
The time between each doubling of output is increasing.
It’s close, but not enough to be exponential growth.
It was exponential for a while but it’s slowing down in the last decade or two.
Such bullsh*t.
“Dear Doctors… You should perform abortions when it’s medically necessary… oh and if we don’t agree it was medically necessary (yet) you lose your license and possibly face criminal charges. - Sincerely Florida”
It’s not an exponential curve. It’s slower than that.
It’s more than linear; we are adding more capacity each year than the year before. But added capacity per year as a percentage of the previous years total is a decreasing.
If it was exponential the growth would be a straight(ish) line when plotted on a logarithmic scale… it’s not. On a log scale the line inflects.
Such an incredibly misleading article.
1 GW of nuclear capacity generates several times more electricity than 1 GW of PV capacity.
Nuclear power plants run at almost full capacity pretty much 24/7/365. With the occasional shutdown every few years for maintenance and to replace the fuel rods.
PVs only generate electricity during the day, and only hit their maximum capacity under ideal conditions. The average output of PVs is 15-25% of their capacity.
Globally we generate more electricity from nuclear than we do from all PVs together.
At the typical sizes we’re building them you need dozens of PV farms to match the energy output of a single nuclear reactor.
Yea basically. Creative accounting abuses of RECs are rampant. There’s no tangible product or service delivered when you buy a REC so there’s nothing stopping a bad actor from selling the same “REC” to more than one buyer.
But more importantly, RECs don’t work to reduce GHG emissions even if they’re purchased and sold in good faith. RECs don’t change anything, that’s the problem. They don’t reduce electricity usage, or change the grid mix. All RECs do is give a company the ability to claim that it was magically someone else’s electricity that resulted in fossil fuels being burned and not their’s. Companies that buy RECs are paying to shift the blame onto companies that didn’t.
Back when solar and wind was more expensive than fossil fuels it may have made sense to offer companies the option of paying extra to get “green” power that otherwise wouldn’t have made financial sense. But now that wind and solar are cheaper than coal and nat gas, utility providers will buy all available green power regardless of RECs.
The bottleneck to building more renewable power isn’t money. Companies paying for RECs aren’t making that happen any faster, they’re just Greenwashing their ESG reporting.
RECs and similar market based methods for Scope 2 accounting are complete bullshit and need to be removed from the GHG protocol.
It’s not driving a transition to renewables just literally just giving companies permission to claim their emissions are lower without actually changing anything.
I read in a firefighter’s thread that the trick is to use a low pressure spray directly on the battery compartment. (It was a thread about Tesla cars not semis though so that might not apply)
The reason was you can’t actually put the fire out, it’s self oxidizing (it can literally burn underwater) so you basically need to wait till it burns itself out. Fortunately batteries only hold something like 1/10th the energy of gasoline and can’t release that energy as quickly so a fine light spray is enough to keep it from getting hot enough to catch anything else on fire including batteries in the surrounding battery modules.
Takes a long time, like hours to get it to a point they can move the vehicle and literally a couple weeks before the reaction completely fizzles out. They have special lots they tow them to where the car can fizzle itself out without damaging anything surrounding it.
I can understand debating whether an intersex or transgender athlete should be allowed to compete in the women’s division at the Olympic / world championship level.
But ffs do we really need to make a federal case about it in high school sports?
This isn’t about athletic performance.
We can’t have solar or winds farms because it might ruin our “pristine viewscapes”… but open pit mining of the most polluting fossil fuel we’ve ever had by a foreign billionaire is totally fine.
Your hypocrisy is showing Danielle.
Tesla’s biggest issue is Musk.
Tesla held a commanding lead over the other automakers in the self-driving segment a few years ago. Now they’ve all mostly caught up thanks to Musk’s unhinged firings. Tesla lost some of its best talent for no other reason than not wanting to work for an egomaniacal billionaire nut job.
Tesla needs to fire Musk before he runs it into the ground just like he’s done to Twitter.
Genuinely curious, what new features did that updated firmware have that were valuable to you?
“Green Hydrogen” is made by using electricity to split water into hydrogen and oxygen. There’re no carbon emissions in that process, but to be truly “green” the electricity must come from a carbon free source like wind, solar, nuclear, or hydroelectric.
The process of electricity to hydrogen to compressed hydrogen to fuel cell to electricity is about half as energy efficient as electricity to li ion battery to electricity. As a form of electricity storage green hydrogen is significantly less efficient than batteries.
Green hydrogen only makes sense as a fuel in situations where batteries are not feasible.
And right now making green hydrogen at all does not make sense because if you build a new low carbon source of electricity it will make a larger impact if you use it to displace fossil fuel based electricity generation rather than using it to create green hydrogen.
Hold a gun to someone’s head and they’ll do pretty much anything you say because they believe their life depends on it.
Morman’s preach that your eternal life depends on being part of their group. So for a transgender person who’s been brainwashed by the church, it’s like having a gun to your head. They don’t want to be in a group that hates them, but they’re afraid “god” will kill them of they leave the group.
They live in terror of being excommunicated (kicked out of the church) because they’ve been convinced that is equivalent to death. The amount of power that gives church leaders over the lives of the followers is staggering, and of course ridiculously abused.
Amazing. I heard she also held the record for the youngest person alive at one time.
There is no year 0 AD. It goes for 1 BC to 1 AD.
What deference would it make if they did?
Moving sheep from on pasture land to another doesn’t change the emissions from these sheep.
The question is what happened to the land these sheep use to be on.
The thing I’m noting is not the part about Harris’s rising approval, but that it has increased the percentage of Trump supporters who are say they are “extremely motivated to vote” to 72%.
Approval ratings don’t matter if one side has a larger percentage of its voters actually voting.
Canada’s population is expected to grow by 500~3000 people daily for the next few years.
Building 5000 units Canada wide is not going to even make a dent in the housing market much less destroy it.
There will definitely be someone trying to take his place.
But I’m old enough to remember the last 7 republican presidents and presidential nominees. None of them were like Trump.
They weren’t convicted felons, or impeached twice, or telling bold provably false lies daily. They didn’t double down on their lies when called out on it.
Some of them couldn’t find a coherent sentence without two hands and a flashlight but went on to be elected for two terms, while still managing not to recommend injecting bleach as a treatment for any medical condition.
Trump has something no Republican candidate in my lifetime (and probably ever) has, blind loyalty in the face of utterly ridiculous behaviour.
It is, but lead based chemistries tend to wear out and need replacing a lot sooner than lithium ion.
You’re core idea is correct though, there’s a lot of battery techs that are cheaper / better when size and weight are irrelevant.
