The owls may indeed not be what they seem but still serve an imperative function: they remind us to look into the darkness.
Re: Electric cars
It's not the concept of an electric car that angers me, it's the idea of some politico trying to dictate my choices. We all have seen examples of how that goes. Legislating how things are to be is not always the most prudent way of going about things.

True. Sometimes however the sheep do need to be led about more than usual.

Re: Electric cars
I wonder how many politicains drive EVs?

Re: Electric cars
Well, with our electrical grid, pushing for total EV transportation is crazy......the grid can't handle it.

Maybe, maybe not. Seems that the grid is routinely mismanaged and also has not been updated forever. Maybe some of the infrastructure money will help. In any case, self-reliance is the ticket - your own solar panels and batteries for charging.

Where did you get your solar panels and batteries. Harbor freight used to have some solar panels. I don't know about the batteries. Are the batteries just lead acid storage batteries.

My son bought them. I'll have to ask. Battery that he has now is a fairly higher end lead acid battery. I'm looking at this system to run small stuff up at the house in PA. I'll know more in a few months after we move beyond the basic test stage, e.g, how well does the system charge and how long does the battery hold per whatever. Buying more batteries probably.....if it runs the lights in the shed and the stuff in the basement crawl space....

‘No way to charge this battery’: Tesla owner left stranded on Christmas Eve when his Model S died in the cold — here's why EVs can struggle when temperatures plunge
https://news.yahoo.com/no-way-charge-ba ... 00238.html
Range reduction
There’s a term called range anxiety, which refers to the fear that an EV might not have enough battery charge to reach its destination. To resolve the issue, manufacturers are now making EVs with longer ranges.
But you still want to be cautious when the weather gets cold.
According to AAA, cold temperatures can substantially reduce the range of electric car batteries.
The organization found that at 20°F (-6.7°C), the average driving range of EVs fell by 12% if a car’s cabin heater was not turned on. The driving range would be reduced by 41% if the heater was on full blast.
“This means for every 100 miles of combined urban/highway driving, the range at 20°F would be reduced to 59 miles,” AAA said in the study.
“When colder temperatures hit, AAA urges electric vehicle owners to be aware of a reduction in range and the need to charge more often to minimize the chance of being stranded by a dead battery.”
Longer charging time
Cold temperatures can not only reduce an EV’s range, but also affect its charging time.
This is because the electrochemical reactions inside the battery are slower at lower temperatures. And EVs’ battery management systems also limit the charging rate to avoid damage to the battery.
A study by the Idaho National Laboratory found that when the temperature drops to 32 °F (0°C), an EV battery took in 36% less energy than when the battery was charged for the same amount of time at 77°F (25°C).
“This indicates that the performance of [Direct Current Fast Charger] can largely vary across the United States due to the variation in regional climate,” the study said.
Tips for the winter
Simply put, batteries don’t like cold temperatures.
Anna Stefanopoulou, director of the University of Michigan’s Energy Institute, points out that batteries “are like humans” and “are weak when they are cold.”
“Our recent work shows that at low temperatures, you cannot charge,” she adds.
“At cold temperatures, it is important to have plenty of energy left so you can start. Don’t think that being near an outlet to charge will get you out of trouble.”
So if possible, park your EV in a garage. Always keep an eye on the battery level and plan to charge before it gets too low.
If you want to go on a long road trip in freezing weather, it’s important to plan ahead. Because cold temperatures can reduce an EV’s range and increase its charging time, you might want to plan for more frequent stops and find more charging stations along the way.
“As long as drivers understand that there are limitations when operating electric vehicles in more extreme climates, they are less likely to be caught off guard by an unexpected drop in driving range,” said Greg Brannon, AAA’s director of automotive engineering.

That's true for conventional batteries as well; apparently they are looking at lithium ferrophosphate for new batteries.

A garage....what a concept. Whatever will they think of next!

Re: Electric cars
Add the cost of building a garage to house the EV through the winter. Make sure the garage is at least 50 feet away from your home so that if and when the battery catches fire while charging, your home may be spared.
If you agree with the Progressives, it's freedom of speech. If you disagree, it's hate speech. There are no alternatives.
Re: Electric cars
cold temps only reduce your battery by 12 percent. Turn your heat off and save 29 percent.

Re: Electric cars
I’ve noticed nearly daily reports in the local (NY - NJ) News about fires being caused by lithium (only?) batteries on those skooters being parked/stored inside people’s homes/apartments/apartment buildings, which seems to have become an ever-increasing danger .
Would electric battery-powered cars parked in a home’s integral garage require their being parked outside , thus having them offered—up (out) to the local criminal ilk?

Well let’s see, risk my EV burning down the house or risk my EV getting stolen? Or driving a gas guzzler I can safely park in the garage. This is going to be a tough one
