Zitat des Tages von Hartmut Michel:
Because of the low photosynthetic efficiency and the competition of energy plants with food plants for agricultural land, we should not grow plants for biofuel production. The growth of such energy plants will undoubtedly lead to an increase in food prices, which will predominantly hit poorer people.
When the yields of biofuels per hectare are known, one can easily calculate how much of the energy of the sunlight is stored in the biofuels.
The future of our individual transport has to be electric!
I was born in Ludwigsburg, Wuerttemberg, in the southwestern part of the Federal Republic of Germany on July 18, 1948, as the elder son of Karl and Frieda Michel. My ancestors lived in that area for generations, mainly as farmers.
