Almost all large scale fueled power (electric, not force) generation uses steam. Wood, coal, oil, gas, nuclear, its all steam power. Combustion power is generally reserved for force power, such as motion. While it can be converted to electricity, it is generally not that efficient in comparison.

In the grand globalist situation, you are almost right. Steam efficiency increases with scale. You would think a steam car would not be worth it, despite the fact they exist and have existed for a long time. Further, you can get more out of steam cars by doing steam-electric cars. The same range as regular electric cars, but without the need to pay for fuel from the grid. It's all a means of control. Use their preferred resource or you don't get to participate. Look at petrol prices. Too late to think about steam cars, you already own a petrol car. Now you gotta get an electric car. Then when they decide to shut the power grid down on you, you can't do a thing.

That being said, a full steam engine vehicle, even without an electric element, needs less globalist industry. If you are less concerned with speed, you can grow your own fuel.

Its more about independence and reliability.
