I'll cover this in one post:
1. Keystone Pipeline may not be an area where alternative energy products will sell well, so not sure you can easily shift those jobs. Though the solar and alternate energy business is booming.
2. Hydrogen doesn't have the infrastructure of electric vehicles at the moment. It is way behind mostly due to Tesla, which has pushed the electric vehicle and made it more viable and scalable than hydrogen cars. In essence, Musk has proven his business concept and has first mover advantage, so he is pushing the market right now to catch up with him.
3. And Tesla's are amazing cars. I usually keep my car for 20 years. I'm 5 years in. I hope to buy a nice electric car in 2030 or so and enjoy the clean air from lack of exhaust. I was smelling the exhaust from cars a few days ago on a calm day with the air filled with some stinking exhaust vehicle. I imagine the day when the road is filled with quiet, electric vehicles that leave no exhaust and make very little noise. It is going to be awesome.
4. Clean energy keeps improving. There is massive investment in this shifting industry. It will have huge demand for employment as it grows. One of my buddy has a well-paid solar panel installment job. He's making good money. Generally requires basic labor skills and if you want to advance, some electrical skills.
5. I've been encouraging my friend in aviation to move into electric vehicle design and production work. That is the future. There are a ton of companies trying to get this electric vehicle market growing. I think in 20 years you will have a harder time buying an ICE vehicle. Electric vehicles offer way too many advantages beyond clean energy.
Some advantages:
A. Faster, quieter, quicker acceleration.
B. Heavily computerized, cuts down on accidents, with auto-driving mode.
C. No bad air.
D. Fairly low maintenance costs from what I understand due to fewer moving parts.
E. Cheaper to charge.
Cons:
A. Charging can take a while and isn't as convenient for quick stops.
B. Manufacturing scaling due to battery technology is not quite there for prices as low as ICE vehicles. Tesla is quickly working on that problem and scaling manufacturing.
C. Government will have to figure out how to pay for roads filled with electric vehicles. Maybe tax on charging once there are more charging stations. Maybe tax on moving. I would think some kind of charging meter for vehicles attached to the charger might be best for charging stations and home charging.
EV technology is moving fast in all developed nations and China worldwide. It should be a major shift in jobs that will hit places like Detroit hard. Tesla is using a lot of robots to build its vehicles, so not sure how many people are needed compared to building ICE vehicles.
Then again robot manufacturing is coming as well. That will require new jobs and a lot of people. Humans are going to become more and more reliant on robots. Best to keep an eye on that tech and invest in it as it explodes.
One technology that sounds super interesting is carbon capture technology.
https://news.mit.edu/2019/mit-engineers-develop-new-way-remove-carbon-dioxide-air-1025 From what I understand they are trying to build carbon capture factories which take carbon out of the air and turn it into fuel. This might extend the usefulness of carbon energy sources. There are some smart people out there doing amazing things. The free market let's you invest in their ideas. Gotta love it.
