Summary:
Dr. Brigitte Knopf works for the Potsdam Institute for Climate Impact Research. She focuses on energy systems and their effect on the climate.DW-TV: Welcome to the program. Scientists from the Max-Plack-Institute suggest that wind energy is limited. What's your take on that?Brigitte Knopf: First of all it's fully correct that there is in principal a physical limit on the wind potential. But it's not relevant for energy supply for the whole world. So it's not relevant for today or for 2050 or even 2100. So nothing to worry about at the moment?Not that much, no.Would you agree that solar power is the renewable that has the most potential at the moment?At the moment yes, it has a big technical potential. But you also have to consider the costs and you have to compare the different technologies and what is less expensive.Most worldwide energy needs at the moment are still being met by carbon fuels: oil, natural gas, coal. Renewables now only cover 13% of energy needs. Only a tiny fraction
