A main criteria for renewable energy is area efficiency
Something I call "renewable reach"
How much mobility can be produced by one squaremeter?
Renewable reach of cars
The technical development in this area is gigantic.
A horse needs about 2 ha = 20.000 squaremeter grass land
An electric scooter as some sort of modern horse needs only 2 squaremeter photovoltaic with 300 W peak to drive 10.000 km a year in a sunny country,
7000km in Germany.
Photovoltaic cheaper than gasoline
