Unfortunately it's also a huge petroleum and natural gas producer. About half of the energy used in the state is for industrial use, much of it for the oil and gas industries. On the bright side, natural gas is displacing coal in the meantime while solar and wind are not replacing it fast enough. It needs to get better, but things could be much worse.

The state produces by far the most electricity of any state, too. It's almost twice as much as Florida.
