Energy is not a physical unit. It is a philosophical concept and an accounting technique used to analyze mechanical and chemical exchanges. In nuclear physics it is defined as a color of light, in biology it is a synonym for metabolism, and in public utilities they say energy when they mean connectivity.
Heat flows from hot things to not-so-hot things. You can pump heat with refrigeration, but that is not a source of power.
