Note that this is about absolute pollution, not relative to power output. Pollution is high, because power output is high. Relatively, for what it's worth, it's just a fairly normal gas plant.

So the most interesting thing to take away from this: There is a lot of demand for more power and in this instance it's satisfied by gas. Which is still much better than coal. Which is still much worse than renewables.

Luckily the Trump administration has just paid over a billion dollars for the second time to stop a renewable energy project...

Mostly because coal is more expensive and slower to build
