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.
