Method to Musk's Madness?

Many observers assume that Elon Musk has been unraveling a bit lately, because that's what it looks like.

But we've got to remember that Musk has occasionally been pretty good at putting over a public perception. Remember, for example, when people thought he was a nice guy who invented all sorts of stuff and didn't care about money and just wanted to save the planet? That was because Musk wanted people to believe that.

Maybe Musk's recent announcement that he has switched from Democrat to Republican, claiming that the Democratic Party has become "the party of division and hate," is just more calculated shaping of his public image.

 

Maybe it's part of his exit strategy from Tesla. It would fit in with a time-honoured tradition of people moving from Left to Right politically, and then proclaiming that their younger selves meant well, but were hopelessly naive. In Musk's case, the stereotypical headshaking over his younger librul self could go something like: "Once I, too, believed that mankind could survive without oil. And I tried my best to make that hopelessly naive dream a reality [...]" And then he becomes a US Senator from Montana, taking some of Montana's wealthy Democrats with him into the GOP. 

Either that, or he really is going completely crazy. Because, Republican and the owner/Dear Leader of one of the world's largest EV manufacturers at the same time -- that's not a good fit.

It didn't occur to me until just this moment that perhaps Musk has announced that he's a Republican precisely because it's a bad fit with leading Tesla. And because he senses that he may have pumped about as much money out of Tesla as he can -- if he can sell his Tesla shares before they become relatively worthless.

Update on Green Energy

Around 2.6 million EV's were sold in the first half of 2021. For some perspective on this, the total number of EV's on the road in the world passed 2.6 million during 2016. At the end of 2019 there were about 7.5 million. That number has probably doubled since then. It's possible that the total sales for 2021 alone will exceed 7.5, although most predictions are closer to 6 million.

 

So, yes, graphs of EV's sales currently show a line going almost straight up. The numbers in the US are much smaller than in Europe and China -- approximately 350,000 in 2020 in the US and around 1.5 each in Europe and China -- but in all 3 regions, 2021 are expected to double the figures from 2020. 

Why are more EV's being sold in Europe and China than in the US? The answer is: the Republican Party and gas, coal and oil companies. There's no big mystery or debate about this: the numbers since 1990 speed up when Democrats are in charge and slow down when Republicans are in power. And the same, unsurprisingly, is true of solar and wind power: the US lead the world, by a large margin, several decades ago, and since then, the GOP, bought and paid for by Big Oil and Coal and Gas, have slowed down progress just as much as they can. The GOP, plus a few Democrats in places like West Virginia and Oklahoma.

Globally, however, there has been a lot a progress. Vote Democratic and help the US join in on this good stuff. 

Other regions which have been held back by the fossil fuel industry include Brasil and Australia.

Globally, we can see a lot of improvement, and a lot of room for improvement. The human race might just survive its habit of burning stuff. Wouldn't that be something.

Energy Efficiency: Fossil Fuels vs Solar and Wind

In the process of powering things with fossil fuels, first geologists make guesses about where exactly oil, coal and gas deposits may be; then miners dig to where they hope the deposits are. Sometimes they have to dig several times before they find anything, because the geologists, after all, were just guessing. 

Once the fuel is found, it is transported, by ship, train, truck, or, in the case of oil and gas, pipeline, to refineries, where the raw material is made into usable products. Then coal, oil and gas are sent, again, by ship, train or truck, or, in the case of oil and gas, pipeline, to power stations, which burn them to generate electricity, which is sent to the grid, where utilities distribute it to businesses and homes. 

In addition, diesel oil and gasoline are sent, by pipeline, tanker ship, railroad or tanker truck, to gas stations and other users. Coal and kerosene are still burned by millions of people for heat and cooking in some of the poorer regions of the world.

The entire trip, from being in the ground to where it is burned for energy or heat, can be dozens, or hundreds, or thousands of miles. Just think for a moment about the distance from Saudi Arabia to the United States. 

Now compare this to solar or wind energy. In the simplest example, the journey is measured in feet, from where sunlight is converted to electricity by the rooftop solar panels on a house and then travels to the house's wiring and to its battery storage. The electricity may travel as much as several miles if there is some left over and it is fed into the grid. Or the distance may be dozens or, in rare cases, hundreds of miles, if the electricity is generated by solar and wind farms operated by utilities. But no ships, pipelines or trains are needed, and the only trucks involved are the ones carrying workers who build, install and maintain the electrical infrastructure. 

Building, operating and maintaining solar cells and wind turbines is a very simple and inexpensive thing compared to mining, refining and distributing fossil fuels. And solar and wind energy keep getting less and less expensive as more of it is generated, while fossil fuels keep getting more expensive. The point where electricity from solar or wind will be cheaper than electricity from fossil fuels? That point is several years ago, and the gap just keeps growing.

Plus with fossil fuels, there are those pesky little details of pollution and global warming. And also accidental fires and explosions.
