State agencies may be immune from prosecution for environmental crime and have no incentive to account for payment of legal damages. Additionally, they may be immune to demand shocks and have no incentive to account for consumer boycott over harmful business practices.
And this is the problem with analyzing things in isolation.
Tell me, what do you think the next step will be after they shutdown?
People need that energy after all - it's not like people will just shrug and go "oh well, no heat for me".
You will actually end up making things worse, under the guise of making things better. Just like a little knowledge is a dangerous thing, an analysis in isolation is worse than useless - it can actually cause you to promote actions that result in the diametric opposite of what you want.
Don't forget that's ~10% thermal efficiency so your really talking about 30% increase in power from the same coal. On top of that they they go for a more complete burn which reduces things like CO and NOx which would otherwise produce smog.
Ahh, I did not think you where pulling numbers from thin air so I just parced it as thermal efficiency so the numbers worked out.
Average coal power plant in the US has ~32-33% thermal efficiency with plenty in the sub 30% range. The best singe cycle coal power plant has 42% thermal efficiency so saying there is a 10% difference is a good ballpark a for thermal efficiency. X thermal energy times (0.3 + .1) is ~30% more than X thermal energy times 0.3.
PS: I do find it hard to be clear when doing lots of efficiency calculations using %'s.
