ABSTRACT
The solar power offered annually in the form of radiation on the earth’s surface exceeds the current energy demand of mankind by 11,000 times. Biomass is the stored energy of the sun. Plants convert solar energy with a mean efficiency of 0.1% by photosynthesis and store it lastingly in their parts – leaves, stalks and blossoms. At optimum boundary conditions the energy in the biomass can be stored almost infinitely without losses.
