There is a problem with coal fired plants. The EPA now requires electrostatic precipitators and scrubbers to remove the resulting fly ash. This includes chromium, vanadium, mercury, arsenic, and cadmium. Half of the man made mercury pollution comes from coal fired plants. A lot of the mercury etc. in our streams, rivers, and in the ocean comes from the rain precipitated particulates. It should now be much reduced although it may take some time for the levels in water to drop.
There is no free lunch, however. A lot of the resulting fly ash has to be disposed of. So the waste disposal companies have pressured the EPA to find places to dump the fly ash. It is being dumped into landfills that are classified for household garbage. Our state is being used as a dumping ground for this and the EPA has classified the fly ash as nontoxic. (They are playing semantic games to cover their rear.) This is as long as the liners do not leak and they all eventually leak. The heavy metals are beginning to show up in ground water around the landfills adjacent to our wetlands. Wetlands that drain into our water supplies. All they have done is create hot zones of toxic metal pollution.
Putting fly ash in cinder blocks is a better solution, but a lot is still being slated for landfills. A lot of the power companies are closing their coal ash ponds. Where do you think this is going to go?
Natural gas has far fewer problems except for fracking. There are also safer nuclear isotopes than uranium and plutonium that can be used for power generation. Thorium is far less likely to cause a melt down and the byproducts decay far more quickly than those from current nuclear reactors. There is more to this, but I limited it to be brief.
