To be green or not to be green – That is no question (for us)

Day by day we search through all kinds of magazines, newspapers, websites, blogs and forums to find exciting articles and news about e-mobility. We aim to be always up-to-date, to learn even more about the industry and to get inspired by innovative businesses and masterminds. Just a couple of days ago we found a really interesting blog post. On blogger Christopher Tan raises the question on how green today´s electric vehicles really are.

From our point of view two paragraphs are especially worth reading. Christopher Tan said: „Let us assume that there is an e-car which is getting charged at home only by electricity from a supplier of green power or by electricity which is being produced by a solar power plant. Then we have an almost emissions-free e-mobility solution. But we have to keep in mind that if only 10 percent of all cars in Germany, which are 43 million, would be e-cars, our current infrastructure could not provide enough electricity from renewable sources.”

CO2-emissions are crucial

In addition Christopher Tan said: „Now, let us do the following calculation. Take the current electricity mix in Germany – wind, sun, water, coal, oil and nuclear – and take the uptake rate of e-cars. Then you can easily find out how much CO2 would be produced by the e-cars if they get charged with energy on the basis of today´s electricity mix. These are some examples of my calculations:

  • Peugeot iOn consumes 13,5 kWh for 100 km – Result: 77,6 g/km CO2
  • Nissan LEAF consumes 17,3 kWh for 100 km – Result: 99,7 g/km CO2
  • Renault Fluence Z.E. consumes 14 kWh for 100 km – Result: 80,6 g/km CO2
  • Tesla Model S 85 kWh consumes 17 kWh for 100 km – Result: 97,9 g/km CO2.“

Emissions-free e-mobilty is possible

Both are important and valid points – also from our perspective. We have already found several studies and surveys which show that people are only willing to accept e-mobility when the e-cars are definitely much more environmentally friendly than cars with combustion engines. Roman Buettner, a well known journalist and automotive expert from Spiegel Online just came to a similar conclusion.


That is why we are convinced that our solar charging station Point.One is the right answer. Considering the weather conditions in Germany the basic model generates electricity for approximately 40.000 km- year by year without causing any CO2-emissions. In Addition our concept is also a good answer to the question on how the infrastructure / the power grid could cope with e-mobility: Due to the solar panels on top of the charging station the electricity is being produced at the point of consumption. This lowers the pressure that is on the grid and increases efficiency because hardly any electricity is getting lost from the point of production to the point of consumption.

On the long run the people will only accept and use solutions that make emissions-free e-mobility a reality. For our solar charging station the blog post from Christopher Tan is another reassurance that we are on the right way with our approach.

In a couple of weeks our concept will prove its road capability when the project “DC-charging station at Olympiapark” will be presented to a huge number of media, politicians, business contacts and the people of Munich.
