CNN is notorious for stretching the truth in pursuit of the class interest of their owners.
AFAIK, the oil companies need a large volume of gas that's free from oxygen. I wonder how energy intensive this "carbon capture" tech is compared to capturing the 78% nitrogen that makes up our atmosphere? This implementation of the technology might be worse for the environment than doing nothing.

A lot of the electricity probably came from burning natural gas at the power plant, and then some of that (~5%) gets lost in transmission. If we assume the natural gas plant is 60% efficient at turning gas into electricity, then an electric heating element in a hot water tank at your house would be about 55% efficient.
A typical gas furnace is about 80% efficient at turning gas into hot fluid, and a good one can reach 95% efficiency.
Depending on the fuel mix of your local grid, there's a good chance that burning natural gas at home will result in less pollution than using electric resistance heaters, either for heating water or the air inside your home during winter. Places like Washington state that generate most of their electricity from hydroelectric power plants will be exceptions.
However, heat pumps can be higher than 100% efficiency. They don't use electricity to generate heat, they just move heat from one place to another. You'll produce fewer emissions overall by using an HVAC heat pump to heat your house, and a heat pump water tank for hot water. Even if you live in a place like Canada, you can reduce emissions by installing a dual-fuel system that will use electricity to run the heat pump weather permitting, and fall back to using gas when the outdoor temperature goes too far negative.
Using heat pumps to move heat from outside, to inside your house, to inside your hot water tank is more efficient than using gas to heat your home and water, even when the electricity to run the heat pump is generated by burning natural gas.

USA already spends more on healthcare than Europe does, they just get worse results and less healthcare per dollar. The US would be able to afford to spend even more on weapons if they got their shit together and de-privitized their healthcare system.

You're not wrong, but that's just growing pains that every technologically capable species goes through. Like every other kind of alien, we have less than 1,000 years to figure out how to move our industry and other energy use and generation off-world before we cook ourselves.

if defederation from the largest instance is equivalent to death for a smaller instance, then the moderators of that largest instance are in a unique position of responsibility and power and should be held to a higher standard

Ideologically, I love it, but I have to wonder - how do the economics of sourcing hydrogen from the electrolysis of water compare to sourcing it from fossil hydrocarbons?
If they compare favorably, then using the hydrogen for chemistry is exciting, but the ramifications of its potential use as a portable fuel is revolutionary (in the sense of making and destroying nation states).

there's no feedback mechanism that will result in the promotion of instances with better moderation
the federation system is inherently unstable - there's a positive feedback loop where the instance with the most users attracts the most new users. new users have no to way to gauge the quality of moderation of an instance, and neither do disgruntled current users. additionally, members of smaller instances are less visible, which is an incentive to join a larger instance.
"what instance?" is a rhetorical question, and the only possible answer is "never heard of it." because there is no means by which a user could have become aware of other instances, regardless of the quality of those other instance's moderation

Avocados and logging also don't need to worry about getting shut down by the law like the cocaine and heroin business does.
Legalize the coke and dope, and the incentive to resort to violence to avoid criminal penalties goes away.

what instance? never heard of it.

Not the first time they've supported a spammer, and their post history is full of Hail Corporate bullshit.
With this person as a mod, the spam is coming from inside the house.

Trades.
If you live in USA, then the Inflation Reduction Act is about to create a bunch of new jobs in heat pumps and solar panels installation. Consider pursuing HVAC or electrician certifications. Solar panel installers also need analytical number crunchers for site assessment.

Back in the day it was the best at what it did, but there's less demand these days for that kind of old fashioned search.
Its still better than the competition at finding the URL of a corporate or government entity. Its still helpful for searching other websites for particular content - for example, the wikis for some games have an obtuse layout and unhelpful search function, and google can be the best way to find a particular page in that wiki.
Before ChatGPT existed, and before the enshitifaction of Reddit reached the critical level its at today, google searching site:reddit.com was pretty good at finding organic human conversations that provide actual answers to your questions.
Today however, ChatGPT is better at providing useful answers to whatever questions you may have. And Bing is better at image search.

This vane engine is sexy and it knows it.
I've recently noticed that downvotes don't stick for the community Greentext@sh.itjust.works. Bug or design choice? Is there a work around? My account is with lemmy.world - do I need to log into a different instance to have full downvote capability? SOLVED - they banned me for downvoting their fascist frogs
