Economize CO2 by renewable energy

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?

Saving by	CO2 saving per kWh	g/kWh
laut Photovoltaic display		700
Electric scooter (5kWh) vs 2 stroke (4l)		1892
Electric scooter (5kWh) vs 4 stroke (3l)		1419
PHEV in town vs Diesel Kangoo		1238
PHEV out of town vs Diesel Kangoo		638
PHEV in town vs gas Kangoo		1280
PHEV out of town vs gas Kangoo		600
7er hydrogen vs 12 C. gasoline		157
7er hydrogen vs 8 C.Diesel		125

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.

CO2 carbon dioxide
	Overview about different aspects of the green house gas prolems. Above all, what will it cost to reach again the normal state?

Traffic energy and environment
	Increasing oil price and more and more consequences of the climate change will enforce an environment friendly mobility.

Hybrid cars
	Why arrived the hybrid car not earlier. What problems solves the hybrid car? Can the hybrid succeed against cars with hydrogen and fuel cells?

45 km/h scooter CO2 emission
	The electric scooter with lead batteries is even with electric power from a lignite power plant better than a 4 stroke engine scooter. The red lantern of the worst has the 2 stroke engine scooter.

Renault Kangoo CO2 emission city traffic
	The Kangoo is an ideal study object about the CO2 emission of different drive concepts, because it exists as gasoline, diesel, natural gas and plug-in-hybrid vehicle.

Renault Kangoo carbon dioxide out of town
	Out of town has also the ICE internal combustion engine a good efficiency. The total superiority of the electric drive system is out of town clearly smaller.

BMW 7 hydrogen
	Electrolysis and liquefaction of hydrogen requires much electric power. The vehicle needs about 8 times more electric power than a plug-in-hybrid of the same size.

Bicycle CO2 emission
	Also the production of aliments causes the emission of GHG green house gases. So even the bicycle driver can not be spared out of a CHG emission calculation.

Carbon dioxide values and how they are calculated
	It often happens, that different CO2 emissions are published for the same process. Overview about different methods to calculate the GHG emissions of a process.
