Yes unfortunately it's not uncommon at all that certain industries effectively get subsidized for their energy use and/or pay less taxes on it. In an ideal world that could be adjusted as well though but realistically that's not going to happen. Example from neighbouring country how crippled things can be: solar would be subsidized, leading to the ones with enough money putting complete factory roofs full with solar, to the point the time in which they'd gain back the initial cost would be a couple of years only. Don't get me wrong, great that they have solar energy, but there's way, way more concumer roofs out there but with an average income the initial cost for them is just too much.
