How much CO2 is produced per KWH of electricity? Quora

Answer (1 of 6): There are several parts to an answer to this question. Firstly there is the CO2 produced actually generating (significant if you are burning fossil fuels, but zero for solar panels. ). This can easily be expressed per kWh. Then there is the CO2 produced to manufacture the gener...
