Unearthing One Hidden Cost of Coal Electricity

Tue Apr 02, 2019 7:54 am

Duke of Coal
Duke Energy just proposed a $76 million initiative for EV charging in North Carolina, but the utility company will have to shell out a lot more than that to excavate coal ash from all of its power plant sites in the state.

The company was ordered to do so on Monday, the Associated Press reports. Six coal-burning plants in North Carolina are affected by the decision, following the previous ordered excavation of eight other plants.

“The science points us clearly to excavation as the only way to protect public health and the environment,” state Department of Environmental Quality Secretary Michael Regan said.

In 2014, Duke Energy estimated it could cost $7 billion to $10 billion and take up to 30 years to complete the work at 14 plants in the state. A sizable chunk of that money — up to $778 million out of the first $5 billion — can be passed onto ratepayers.

I take my coal ash and mix it with concrete.

Good thing coal is being phased out.

So does industry, but ~ 57% of the ash turns into toxic swamps.

A little Googling says that 'fly ash' can be recycled into concrete but 'bottom ash' and FDG ash cannot.

So you tell me: is coal combustion for electricity "cheap" ?
Answer: only if externalized costs are ignored.

Why do Repukes and Trumpers have such a hard time understanding this ?!?

I have rooftop solar. I just *know* it's gonna give me skin cancer, because sunlight.

If not coal, then what kind of capacity should have been built from the early 1980s through 2000 when huge amounts of capacity were being added?

Nuclear.

After 2000, natural gas combined cycle plants. Which we did do, and much of the coal is offline. Natural gas releases less CO2 than coal per unit of heat, and a ng plant can produce more than twice as much electric power per unit of heat than coal.

Today we should be adding solar + storage.

It may have been the most feasible choice, but burying the waste was a mistake. Had the full cost of the coal been clear up-front, then alternatives may have come on line sooner.

Judging by the externalized costs -- ANYTHING but coal. And that is the point.
