I thought this place was full of pedantic engineers, like me? The steam engine turns energy into work. If anything, it probably increased the price of energy (at least temp…
If you're going to be pedantic, at least be correct.
If you were to consult your physics textbook, somewhere near the beginning under the heading "Conservation of Energy", you'd see that the steam engine neither creates nor destroys energy, merely transforms it into a different form.
