To get independent from fossil fuels, we have to developed new processes. As shown before, we are limited in arable land. That means, we would have to convert a lot of arable land to grow food and even more to monoculture of energy crops to get enough biomass for the production of biofuels and other important products. This however is not an acceptable option. | To get independent from fossil fuels, we have to developed new processes. As shown before, we are limited in arable land.
