I’m 54 and spent 20 years teaching overseas. I really miss the fast bullet trains 🚅 in China and other countries . They were amazing. Easy inexpensive and comfortable. Please, Secretary Buttigieg, lets have those and other public transportation here in the USA 🇺🇸. I live in Daytona Beach Florida and in the country in Aguadilla puert Rico . Cars are sooooo expensive. 😢. There are so many other inexpensive things I loved from other countries. You can ask me about them. Thanks so very much. You’re doing a terrific job. Maybe, non vehicle users could receive something extra since were helping the earth.

Yes indeed let’s electrify our transportation but since 70% of US electricity is generated by burning coal wouldn’t it be more efficient to go back to steam engines?
Big coal plants are ~60% efficient at turning the chemical energy in coal into electricity. Gasoline engines are only ~15% efficient and diesel ~20% efficient. If you account for electrical transmission, battery, and electric motor efficiencies electric cars end up being able to capture ~50% of the coal chemical energy to useful energy. Also at least some electricity comes from renewable and nuclear. So having an electric car positions you to take advantage of increases in renewable energy over the lifetime of the car.
@@sethsims7414 I have to amend my original statement. 70% of electric generated comes from burning fossil fuels. That includes coal , oil , and natural gas. What you say may be true but the life of an electric car equates to the life of it’s batteries. The batteries in an electric car are located under the floor of the car making it necessary to definition of construct the car to change them and as the make up a sizable portion of the cars value when they expire so does the economic viability of the vehicle
@@sethsims7414 From what I’ve read 100,000 miles is about average though there have been examples of multiples of that number. The real issue comes in the used car market. Would anyone buy an electric car with 100,00 on it when that’s considered the average lifespan ?

Whole lot of ifs

Necessary to deconstruct the car
@@herbertbrown119 Eh, my electric car is nearly 8 years old and hasn't shown any significant battery degradation.

Also, totally the wrong time to move out of the afghan region... if this is the future. That's where all the rare earth minerals are, dummy
