In that case we need to include storage inneficiencies too.If you were storing energy from a coal-fired plant, then you would need to include storage inefficiency in calculating the CO2 output.
- But if the electricity from rooftop solar is being temporarily stored in a car battery, there is no extra CO2 output due to power lost in charging/discharging the battery.
- There is the additional possibility that stored rooftop solar power could displace peak-hour fossil power, reducing CO2 output.

electricity looses about 30 Percent in transmission.
Quote from: Wolfekeeper
n the UK, transmission losses were 7.5% as of 2017This is only important if you are generating your power from CO2.
- If you are generating power from green sources, the transmission losses do not cause an increase in CO2 emissions.
- And if you are generating power from your own rooftop solar, the transmission losses will be a lot lower than 7.5%.
