Everlasting energy is very much the same thing.
How to sell it to energy producers though?

Easy

But everlasting energy can't possibly happen
The laws of entropy dictate that you can't get more out of a system than you put in, and thermodynamics make 100% efficient engines impossible, so while you may discover a cheaper form of energy, it will still require infrastructure, which someone will have to pay for and maintain, so there will always be a cost, though it may be much lower than those we currently have.
