"I bought the energy, I paid for it, so I can use it to do whatever I want" is such extreme capitalist thinking.
Where does this energy come from? Of course from the fact that someone arbitrarily claimed it in the past — either because they had influence, money, power or simply were the first to claim it. They claimed coal/oil deposits, they claimed the land to build power plants on. They "produced" (or rather converted) energy and now they're selling it.
Where does your money come from? Most likely you're getting it because you're turning some cogs in the grand machine of capitalism. Once you skip all the middlemen, this eventually boils down to the same thing — someone claimed some resource in the past, and used it to make money.
Humanity just loves to claim everything. Natural resources are theirs to take. All land is theirs to take. Air is theirs, water is theirs, nature is theirs.
Who cares if they're destroying everything? They worked hard and they paid for the right to do so!
