  • KWh into CO2 emission equivalents

    Anybody know where I can find a conversion table that helps convert KWh of electricity consumption into kg og CO2 equivalent depending in the first instance upon country?

    I would also like conversion tables based upon discrete energy sources (oil, coal, natural gas etc)

    I have only been able to find statistics covering individual countries.

    Many thanks,
    Stuart

      How do i convert KWH into lbs of CO2 emissions from burning
      natural gas to produce electricity

          Can you tell me how much c02 is generated from 27,945,027,.5 KWH

            From the list, Natural gas is 0.185kg/KWh
            8058720KWh x 0.185kg/KWh = 1,490,863 kg

              i'm setting up an payback sheet (ROI) and i need to know how to convert kWh in to CO2 in both imperial tonnes and also kg. any help please?

                Kilowatt hours of electricity? How is it produced? Some countries publish average figures for their mix of power plants, but it changes over time as they go to more renewables, build new power plants, obsolete old ones.

                Even for averages, it will depend on the fuel the power plant burns, coal is worse than natural gas. Solar, wind, hydro, and nuclear are essentially zero in operation, but some is produced in building the plant. Individual plants of a given type (coal) vary in efficiency. (NOTE: Solar may cheat. Solar thermal plants are allowed to burn up to 25% natural gas to warm up in AM and hold power as the sun goes lower in late afternoon peak. Hence they produce some CO2. Typical is 24.99% because if they exceed 25.00%, it is no longer "solar.")

                There are no Imperial tonnes. The tonne or metric ton is 1000 kg. There is an (obsolete) long ton of 2240 lb used in the UK, and hence Imperial, and a short ton (2000 lb) used in the US, and hence Customary. Which ton are you trying to use.
