I was under the impression that natural gas was twice as good as coal[1]? 50-60% less CO2. not perfect but far from "not much better" in my opinion [1] https:/

- DebtDeflation 7y agoDon't forget the heavy metals (lead, arsenic, mercury), radiation (coal ash is literally more radioactive than some nuclear waste) and particulate matter releases that come from burning coal. Natural gas isn't optimal but it is FAR better than coal.
- jhayward 7y ago> coal ash is literally more radioactive than some nuclear waste Please do not repeat this nonsense. It either compares non-power-plant waste (lab gloves used in isotope labelling, for instance), or is so wrong as to be ludicrous. Used nuclear fuel is billions of times more radioactive than coal ash.
- ecpottinger 7y agoYes, but that nuclear waste is in storage pools. The waste from the coal plants is in the air we breath and the ash-spills effect the water we drink. Or better yet, walk around an operating nuke plant with a radiation detector and then do the same walk around an operating coal plant. I am willing to bet the coal plant will spike higher.
- jhayward 7y agoIf that's what you mean, then say "coal ash ponds emit more radiation than can be measured outside spent fuel cooling pools". "Coal ash is more radioactive than nuclear (power) waste" is a completely difference factual statement and is untrue by many orders of magnitude.

- fred_is_fred 7y agoAlso all the dead coal miners and dead people from coal ash spills.
- _bxg1 7y agoTrue, but climate change is the true catastrophe at hand; I'd say it takes precedent over those other (still important) things.
- WhompingWindows 7y agoIt's not just the CO2 picture for emissions, keep in mind methane is a far more potent GHG and there is going to be some amount of leakage in the workflow of getting gas from fracking to the turbine. Colorado has the gold standard regulation for methane emissions, check it out: https://www.denverpost.com/2019/04/24/colorado-regulators-new-rules-oil-gas/ https://www.denverpost.com/2019/04/24/colorado-regulators-ne...
- ZeroGravitas 7y agoIt also has some potential for being gradually replaced, like mixing in renewable hydrogen, using methane captured from closed coal mines that would otherwise leak, methane from food and farm waste etc. and those then transition into being carbon neutral or negative ways to store energy for rarely used peaker plants to support the grid.
