In Germany, wind energy is the number one renewable power source. Offshore wind farms in particular require innovation, since they must be planned and built to withstand the wear of wind, water, salt, UV rays and waves over the 20 years or so of their service lives. Photovoltaic systems and solar thermal systems are what allow us to harness the sun’s energy for our use. Fraunhofer researchers are hard at work trying to make these systems even more efficient. Meanwhile, Germany now has a significant market for biomass energy and one of the primary aims of modern biotechnology is finding a way to produce biomass efficiently.
