Energy usage car changing

Until now, the consumption was only measured in litres of an crude oil product. The new norm is the earth surface to produce the necessary energy.

Plug-in Hybrid 80% electricity - 20% fuel

When it is possible to drive each day with a fresh recharged Plug-in Hybrid the first 50 to 150km electric only, this would cover about 80% of all journeys. So in the first approach, this would reduce the fuel usage by 80%.

Wrong, because this would be with all cold starts and partial engine load At a Plug-in Hybrid the range extender works always with the optimal load for low consumption.

Consumption of Plug-in Hybrids

The Renault Kangoo 14,4 kWh in town 19,6 kWh outside town. At the Opel Flextreme after first data 3,5 Liter Diesel or 4,2 Liter gasoline in the range extender mode. The consumption in electric mode is assumed by me with 15 kWh/100km.

Because the Renault Kangoo is a high built van, I would assume 15 kWh/100km outside town and in town for Plug-in Hybrids in the middle class. At a mix of 80% electric mode and 20% range extender mode, this would be.

12 kWh electricity and 0,7 Liter Diesel or 0,85 Liter gasoline for 100km

Better than a 1 Litre car

Electric power from sun and wind and less than 1 litre fuel for 100km. Is this reduction enough, when the oil production decreases below 50% and billion Chinese and Indians purchase cars?
