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.
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.
The battery's chemistry isn't important to the end user. Price, capacity, longevity, and charge time is. If we assume CATL inflates their stats by the amount that's standard for their market, we can infer their new battery is almost as good as Tesla's old battery in terms of mechanical utility to the end user - their only hope of competing is to win big on price.
I hope they can win that competition. I'd love to see GM produce an EV that's almost as good as a Tesla and a lot cheaper.
Avoiding GM and using the most current tech are both bad ideas, for the same reason: Tesla is owned by a horrible person.
After subtracting the expected quantity of deception in Chinese advertising, this new battery tech from China is still not as good as what Tesla has already been making for the last several years.
Wait a minute, companies that run charging stations now want local businesses to pay them for the privilege of installing one of their chargers? Instead of the company selling the recharging to EV owners paying the local business rent for use of their real estate?
Right? Venus, Earth, and Mars should all be pretty similar. Mercury should be about the size of the moon or a little bigger. Jupiter doesn't need to be fuck off huge, but at least a bit bigger than Saturn.
