Usually, the electric power production by renewable energy is compared with the production by fossile energy and the CO2 saving is calculated by this.
This display of a photovoltaic system calculates the CO2 saving with 700 g / kWh. But how much can be saved in the mobility by solar power?
CO2 saving per kWh

Electric scooter (5kWh) vs 2 stroke (4l)

The possibilities for CO2 saving by electric mobility are in city traffic and with small motorcycles clearly bigger than against the fossile power plant mix. The savings are at the combination hydrogen / ICE internal combustion engine in BMW 7 very smallt. This even though the 8 cylinder Diesel with 9.5 and the 12 cylinder gasoline with 13.5 litre are no economical vehicles.
