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.

It depends on the jurisdiction, but in most cases if you have a salaried position with say 3 weeks of PTO but you only take 2 weeks of it. The employer is usually required to pay you over and above your salary for working during your “vacation time”.

If there’s an unlimited PTO policy, they don’t have an obligation to pay you extra for working during vacation time.

It’s a lie.

By making it “unlimited” they don’t need to pay you out of you don’t use all of PTO days.

If you use it more than they think you’ve earned you get terminated.

Employees end up afraid of taking their PTO days and typically end up taking even less time off than if they knew there was a expectation of 3 weeks or whatever.

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.

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.

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.

Your math checks out.

Charging a 600 mi battery in 9 minutes would require a charging station that can output somewhere north of 1.2 MW.

We need major upgrades to the electrical grid as well as doubling our electricity generation capacity for charging stations and vehicles like that to be common place.

It’s not like the country was massively relying on nuclear energy at any point in time really.

Germany’s 17 nuclear reactors were generating almost 30% of its electricity a decade ago before they started phasing them out. It was their second largest source of electricity after coal.

Despite having built literally 100s of solar and wind farms in the past decade they still had to increase their coal output by 40 TWh to make up for the gap. A nuclear reactor generates a fuck ton of electricity.

And for what? Statically speaking 800x more people are killed in coal mining accidents per TWh generated than are killed by all nuclear power accidents combined. They phased out their largest source of carbonless electricity and the decision likely killed more people than would have died even if there was a nuclear accident.

I remember a time when ads weren’t crazy intrusive. They weren’t being shoved into every os and app and website.

There wasn’t 20 of them on every page, and advertisers weren’t trying to harvest my data to the point where they knew every last detail of my personal life.

And I didn’t mind having them in order to have “free” content. But they got greedy and now I’ll block them in every chance I get.

Maybe forcing ads into everything isn’t the answer.

I feel genuinely bad for any democrat supporter with an ear injury right now.

You’re not wrong.

Wholesale prices do bounce around significantly in a day, occasionally even going negative. And some miners do shutdown for brief periods during high demand due to a high electricity price. Some miners aren’t buying electricity from the grid, and have their own generation sources with different economic inputs. And there’s lots of day to day volatility in mining rates that has nothing to do with economics.

There’s no formula or methodology that could tell you how much energy is being wasted at any given moment. That impossible. There’s no way of knowing how many miners are operating globally at any given point in time. We can’t even reliably tell which country a block was mined in. We can only make reasonable estimates of global averages over the last few weeks.

You can get closer with more detailed modelling, but the equation I gave using global averages for bitcoin and electricity prices in the last few weeks will get you to an accurate estimate.

Yes somewhat… the formula has several factors that are constantly in flux, Bitcoin mining is a random process the value can be off entirely by chance. But it’s designed to self-adjust over the long run towards that formula, individual fluctuations cancel out in the long run.

For electricity price specifically, wholesale prices of electricity tend to be fairly close everywhere bitcoin is mined. Bitcoin mining is more profitable where electricity is the cheapest and is uneconomic in places where the price of electricity is above average. So it only happens where the wholesale price is globally competitive.
