Chevron Won’t Cut Oil & Gas Business For Renewables | OilPrice.com

This is a good thing. Without oil and gas the EV evolution will NOT happen. This fact came straight from the mouth of Elon Musk.

Probably a good thing there will be diversity in the market but they better be careful their shareholders don't revolt:

"At Chevron, 61 percent of shareholders backed a proposal at the annual general meeting last month that the company cut its so-called Scope 3 emissions, the ones generated by the use of its products, rebuffing the board, which had urged shareholders to reject it."

This part makes you wonder what's going to happen to oil prices down the road:

"Shell, for example, affirmed earlier this year its oil production peaked in 2019. BP looks to slash oil and gas production by 40 percent by 2030, while Eni sees its oil production peaking in 2025."

The next couple decades are going to be very interesting.

Solar cells that make use of wasted light

Solar cells need enhancing in efficiency and longevity.

I remember Tesla and maybe others trying for solar on their experimental cars.
Didn't work in garages and throughput to weight was not good.
Maybe as they get the efficiencies up on solar this will change, but not soon.
Maybe give away solar panels with each new car

Aptera still is, If they ever get it into production
Sunny day it is supposed to charge up to 40 miles.
Drag coefficient is .13
Crash tests and other testing still need to need completed, Interesting look to its 3 wheel design body work. Inside the cabin is somewhat Tesla like.
Not sure it would be confidence inspiring driving it in a wind storm.

20 years from now the world of EVS may be in a very different place.

Chinese steel futures rise; coking coal, coke log weekly gains

Their EV efforts are driving their steel industry as they build out to meet the world's demand for EVs.
.

You are convinced that Chinese steel is going for EVs and industry?

Do you talk with any in our military? Are you aware of their military build up? They are building the world's largest army, navy and air force. My guess is their military expansion need is equal to or greater than their EV driven steel needs.

EVs require little steel but their factories, rail, ships and delivery trucks require steel. EV sales will enable China to develop other technologies and objectives in a top down manner I expect but that's a subject for a different forum.

Tesla's new motors are revolutionary in their energy efficiency. I wonder if the technology is applicable to generators? Whatever you use to turn the generator shaft, a 2% increase in efficiency means heat dissipation is reduced and the equipment will run longer.

I thought gas generators were illegal in California. I thought I read all generators had to be battery powered.

You guys need to read more credible sources. See my sig quote, below.

A car with solar panels on it is a long way off. Panel efficiency is far below what would be needed.

I have an old photo of my daughter visiting a friend's experimental solar car competition. His team built the car in a UCB lab. It was ultralight like a recumbent bicycle. As noted in a post above, wind might have tossed it around same as a sheet of plywood.

It was way underpowered for even moving that light weight around. Panels today are likely some multiple more efficient, but still way underpowered for practical use. Except maybe at noon in open desert with no shadows anywhere.

A rare new coal mine in southern Colorado adds to Trinidad's economic revival

Coal may not be cool today but without steel where would we be today?

Not U.S. owned and product will be shipped overseas.
"“Our strategy is to provide metallurgical coal to the seaborne market, not the U.S. steel market,” said Mark Gray, the chairman of Australia’s Allegiance Coal Limited, . . "
