This doesn't surprise me. It also will drastically increase demand for copper.I have seen people talking about it but not policy making people, simply critical thinkers and they all say it's impossible unless there's a massive overhaul in electricity infrastructure both in delivery capacity and production which sound like a colosale task.
Oh my gosh, yes. Lots. I think you can almost see the eyes glaze over as people try to figure the impact of EVs that might be able to be bi-directional, absorbing energy when the price is low (or demand is low), and returning to the grid when the opposite is true. That's without getting into microgrids, home batteries, etc.I have always wondered if anybody has estimated future use vs planned generation and transmission needs based on the new vision.

The tax breaks are what stuck us with the dependence on fossil fuels. Other than road taxes, the only tax on fossil fuels I am aware of is Texas, which taxes every teaspoon of crude. Are there taxes on coal and natural gas?That be nice... I wrote that because of the EV argument treads over the years and apparently according to the research of some individual the electricity is supposed to get cheaper (I don't doubt they actually found that information) as the years comes despite a aging infrastructure, growth in population and increase in demand. So because of that I don't believe it one bit, electricity will become more expensive it simply has too and they will tax the fossil fuel to keep electricity cheaper then fuel to sell their EV mandate.
I was talking about the future, it will come, that's what they are doing in Canada and other part of the world.The tax breaks are what stuck us with the dependence on fossil fuels.

Around here, transmission lines are copper clad steel above ground, aluminum underground. I ran across an article years ago that one of my college buddies, John Stovall, was Engineer In Charge of the "first commercial superconducting power line." If anybody could do it, John was the guy. He was scary smart. That was years ago and nothing ever came of it, so that technology is still waiting in the wings. Superconducting DC transmission lines would make wind power practical.As the voltage goes up, aluminum becomes the preferred conductor, so probably not much in reality. Copper is 58% more conductive by density, but weighs 3.3 times as much. For home use, where there are lots of little connections to make, copper is more resistant to installer errors, and less prone to thermal expansion damage that leads to loose connections and fires.

I've been asking my question for years yet most answers are actually the same expense writeoffs which every other business gets.The tax breaks are what stuck us with the dependence on fossil fuels.

Entire California water districts with abundant water were without residential meters… friends both in Sacramento and South Lake Tahoe were on such flat rate systems…The only person who said this was Lewis Strauss, head of the Atomic Energy Commission, who wasn't an engineer. His analogy was to water which he said was too cheap to meter. I'm not sure where that came from since I've always had a water meter.
You have never heard of an oil depletion allowance? It allows the oil companies to deduct the value of the oil they pump from their bottom line.What tax breaks?

There's been a superconducting feeder in operation at Fermi labs for forty five years or so, but I think that the trick isn't the lines, it is finding a superconducting material that doesn't need to be at -452F.Around here, transmission lines are copper clad steel above ground, aluminum underground.

Redesigning the grid for distributed generation will certainly be expensive. I just saw an article that Switzerland (?) is experimenting with lining the space between rails with solar panels. Uploading the power to the rail lines would be convenient, but trains don't use that much power. I doubt rail lines could handle megawatts, particularly at their low voltages.
The math in the prior post was for equal amperage, so apples to apples. I think that the larger diameter of the aluminum is a little misleading due to the lower density, which means a larger diameter to get enough material to conduct the same current with the same resistance.View attachment 4007319
Copper may weigh more, but that difference becomes less when you need twice or more aluminum to provide the same amount of power.
Aren't a lot of EV's leased? So the guy who leased it would be thinking about his net electricity cost, rather than the car's battery life.As for using your EV or house batteries to feed the grid in times of high demand/low supply, the additional charge/discharge cycles will wear them out faster. Maybe the compensation from the utility company will offset the cost of replacing the batteries, in the case of an older EV they might not be worth replacing. Win for the EV makers...
I had to think about this for a while. (I also deleted a previous reply.)You have never heard of an oil depletion allowance? It allows the oil companies to deduct the value of the oil they pump from their bottom line.
It depends a lot. Older grid batteries were, and are, using lithium ion batteries (e.g. Tesla), just like phones and laptops. Newer grid scale batteries are more commonly lithium iron phosphate batteries, also used now in many EVs, e.g. BYD, Tesla, and a few others.I expect grid batteries to be a different chemistry than EV batteries. There are cheaper and more durable batteries not used for EVs because of weight and energy density considerations. A substation could just add an acre.
Agreed, as aluminum conductors weigh approximately 3 times less for the same conductor size vs copper.There's been a superconducting feeder in operation at Fermi labs for forty five years or so, but I think that the trick isn't the lines, it is finding a superconducting material that doesn't need to be at -452F.
