Litre for 100km in kWh
You think Your car drives with Diesel or gasoline and has nothing to do with kWh. But CCPP combined cycle power plants can convert gasoline by 58% efficiency to electric power.
With this values, You can convert Your l/100km values for gasoline or Diesel to kWh/100km, based on the electric power, a CCPP could produce out of the fuel. A typical medium sized plug-in hybrid has about 15 kWh/100km.
A small car about 12 kWh/100km.
The LOREMO reaches even 6kWh/100km.
But there is even a bigger difference than kWh/100km alone. The prices for fossile fuel are going straight in the sky. The prices for photovoltaic declines. A gasoline car remains always a gasoline car. A plug-in hybrid can drive in the electric range with electricity from any source. We are already after the turning point where photovoltaic is cheaper than gasoline.
