This YouTube video by Tony Seba is stating that utility scale batteries of 2% disrupt 90% of fossil fuel peaker plants. This video has a lot of graphs showing the trends. https://youtu.be/AV3MweskE0w The amount of utility scale batteries needed to replace much of the peaker plants is just a small percentage. 200 mile range EVs

From FB reply I’ve read there is research about feeding seaweed to livestock to reduce methane. The livestock industry has had manure digesters that produce enough power to run the dairy farms, and this is a mature technology. They could also run the farm equipment using compressed methane AKA natural gas. In any case the

Here’s a TED read. It’s extremely important that the world cut CO2 equivalent emissions in half by 2030 and continue dropping after that. For the US it’s now at about 51 gigatons per year, and this needs to drop by half to 25 gigatons per year. The electricity sector needs to decarbonize in order to

From TSLA group – about hydrogen from my blog previous to this one. Nick Carrière Said, “…fundamental flaws with hydrogen vehicles…” Well, first off ‘converting to AC for a motor’ is necessary for battery EVs, too. But the losses are only a few percent either way. Said, “Total energy losses are several times higher…” That

Which pollutes more? This video shows how much the oil and gasoline industry pollutes. https://youtu.be/1oVrIHcdxjA
From my FB reply to many negative comments by this hypercritic. Ned Goldston *No* EV owner needs to have a solar panel system to charge their EV with green electricity. In California there are no coal power plants and the natural gas plants are being replaced with peak shaving utility scale batteries. At times of

My replies to article cited by an “electrical engineer with 34 yrs experience”. https://returntonow.net/2021/02/09/the-spiraling-environmental-costs-of-lithium-batteries-could-rival-fossil-fuel/ << Ned Goldston Thanks for the link to the article. The article is written with false information (e.g. li-Ion batteries cannot be recycled), the reference used is at least 8 years out of date, and the most telling is the last

Cathie Wood talks about EVs at about the 20 minute mark in this YouTube video. The first part is economics. She talks about digital wallets. She thinks 200 million digital wallets in the US, and it will put financial institutions in harm’s way. As part of automation, she talks about autonomous ride hailing. She says

This setup just charges the battery as long as the resistor is connected to the field coil. There is no regulation of the charge and it can overcharge the battery. To properly regulate the charging, the alternator should have a regulator instead of the resistor. The regulator will shut off the charging when the battery
