Almost no cars, trucks, or tractors are steam based anymore. I believe most ships are ICE as well, not to mention rockets, and animal/muscle power. As such I'd need a very deep analysis of the situation to believe any claim. (deep because in an ICE a large part of the power comes from burning fuel producing steam, so we can start debating how much of an ICE is steam - have fun).

In any case my local electric utility generated more power from wind than all customers used last year, so I can make a good claim most of my power isn't from steam. If your utility isn't in the same situations or close you should be demanding they get with the times.

And your moms power is hip based.
