Charging stations for each house are duty, but climate-friendly are electric cars only with pv or wind power

If it goes according to the eu commission, will be compulsory from 2023 for new buildings and refurbishment of the installation of a charging station for electric cars. Every house should then have at least one loading point. In coarse buildings, parking garage and underground garages should be at least every tenth parking space.

The new, 1.2 billion euro electromobility program of the federal government relies on the installation of 15.000 new charging panels. This is intended to despoll the good and often even time-critical search for a power connection and make the electric car more attractive. But there is an electric car, refueling with normal mesh stream, in its climate balance really as much better as a burner?

Coal flow ranges the climate balance of electric cars

Especially the high proportion of coal flow ranges the electric cars still the balance sheet. In germany, the electricity in the network is already generated to a third of regenerative, while the production of a kilowatt-hour mains power are still 535 g of co2. For a small car like the renault zoe with a consumption of 15 kwh / 100 km are then 81 g co2 / km. A gasoline with a consumption of 5.9 l / 100 km comes to 140 g co2 / km.

The promise of emission-free driving loose electric cars so only when the energy supplier of the charging panels or the wallbox explicitly provides 100% okostrom. Or if the driving stream is loaded directly from the pv system at the house. The nail sample will come 2022 if the akw will go from the network in germany and must be replaced by the 14% share in power generation. Then, there will be on whether the coal mighters will be preheated correctly and discredit all the electro-type or whether the forced settlements for pv and wind power plants are lifted and implemented vehicles-to-grid concepts. Thus, the electric car became part of the energy system as a storage.
