The deadly Camp fire where 86 people died was caused by a broken hook that was badly worn. PG&E was convicted of crimes for this and others. The company had to go bankrupt to protect its finances.

2021-12-27 13 Battery Factories To Be Built In US
There will be (at least) 13 new battery factories to be built in the US by 2025. They forgot to count Tesla’s GF Texas battery manufacturing plant.

The biggest problem is to get the raw materials. That is establishing the supply chains for lithium, nickel, cobalt graphite, to name a few. And for LFP cells they will need iron and phosphate. One article said that Morocco has 70% of the world’s reserves of phosphate.
2021-12-27 OMG! China To Install 1200GW Solar & Wind By 2026!!
OMG! China is expected to install 1200 GW of solar and wind by 2026! To give you an idea of how huge an amount that is, the total electric generation for the United States is about 1200 GW! That is an enormous amount!
Quote from article:
<< China is expected to install 1,200 GW of total wind and solar capacity by 2026, according to a new report released this week from the International Energy Agency (IEA). That’s four years earlier than the country’s current target of 2030. >>

There is *one* thing you should learn:

All of Trump’s lawyers and all of his men
Couldn’t put Trumpty back on his throne again.

2021-12-26 Death Of California Rooftop Solar?
This guy goes over the changes when NEM 3.0 takes effect in 2022. The smaller bill with lower solar power will be at a disadvantage and there will be a disincentive to get rooftop solar. In other words the owner will save minimal or no money over the lifetime of the system. Also the solar installation will require purchasing a battery storage. The only ones who will save a decent amount will be those whose bills are $200(?) or more.
Another video about this, he basically reads an article from ?? He talks about California imposing an 8% solar tax.
2021-12-26 Space Based Solar Arrays
My comment from JHAT of this date with subject of space based solar power stations
I pose the question: Should we (humans) collect solar power and beam it down to Earth by microwave or laser?
The answer, and I quote, is “No. Don’t be ridiculous.”
Are you serious? Who in their right mind would attempt to sling that much hardware into space and waste all that much energy to accomplish something that would be thousands of times easier.
That something is simply putting a square mile or more sheet of metallized plastic, rolled up, into orbit, and unfurl it in space to become a mirror. Leave all the solar panels here on Earth where the light from the mirror will be directed. This would allow the solar array to be illuminated in the direct sunlight by day and by the mirror at night.
This mirror could be made mostly of metallized plastic, with structural members made of tubes of metallized plastic that once in orbit are inflated with dry air to become stiff enough to support nearly no weight. The structure would be ultra light and a huge amount could be deployed from a single launch.
If you really think about it, it would be absurd to do it any other way. By the time a kilowatt of sunlight hits the solar panel in the sky, gets converted to microwaves, reaches Earth, and gets converted to electricity, there would be less than a hundred watts left, probably closer to 50 watts.
And there is no worry about frying anything with microwaves. Just freaking out nocturnal animals like owls. 😱😂
Thanks, Dave. Am I the only one who has proposed this system? There must be some other “best scientific minds” that have rationally thought about this!
2021-12-24 Renewables Vs Fossil Fuels: VALCOE
Engineering with Rosie dives into the VALCOE – value adjusted levelized cost of energy. This is adjusted for time of use – most solar is available only during daylight hours.
She uses a car race analogy to compare the solar, onshore wind, coal and gas. Solar and wind win the race.
One thing I didn’t understand was the graphs showed gas combined cycle, but she talked about gas peaking plants, which are a completely different VALCOE.
She used several charts from Lazard, version 15. They’re very informative.
She said that solar is not available after the sun sets. This is not true for one type of solar: where the Sun heats fluid that is stored hot for use after dark to generate power.
She showed the ‘duck curve’ of South Australia electric load and how at times there was negative load, the electricity generation exceeded the load. If the hydrogen generation projects had been completed, this would not have happened since excess generation would not have to be curtailed, but instead used to generate green hydrogen.
2021-12-24 Small Scale Solar: Calif Leads with 10+ GW
California leads with more than 10 GW, many times that of second place. Texas and Florida are adding a lot more. The incentives are important! They don’t say, but I assume that this includes ‘behind the meter’ rooftop solar.
2021-12-24 3 Solar Farms In Riverside Co. On Federal Land
The Biden administration is approving 3 large solar PV farm projects on BLM lands in Riverside County, California. These utility scale projects total nearly 1 Gigawatt capacity. Up to 25 more will be built in other states.
