I’m interested to know how much Co2 is generated by a coal fired power station to produce 1kWh of electricity for electrical grid

  • $\begingroup$ Welcome at EarthScience.SE. Which resources did you use in trying to answer the question on your own? Looking for "co2 emissions coal fire plant per kwh" in your favorite search engine should yield a huge heap of useful results. It looks a bit like a homework question. Moreover, I am not sure whether this question is in the scope of EarthScience.SE. I am voting to close this question. $\endgroup$ Commented Dec 4, 2017 at 23:45

About 900 grammes of CO2 for each 1kWh of electricity.

There is some variation: very modern super-critical coal plants can be lower. But 900g is a reasonable central estimate.

Note that that's just CO2 from combustion. It can be higher, when we include CO2 and CH4 emissions from the rest of the coal supply chain too.
