12 | 13 challenges in renewaBle energies // windwerk – independent wind and solar farM services energy market ChALLENgES IN RENEWAbLE ENERgIES on a global scale renewable energies are already producing a sub- stantial share of our energy and in this way they are making a signifjcant contribution to protect our planet. they are the energy of the future. germany as one of the world’s most important industrial nations has decided to cover 100 % of its energy supply by renewable energies. the restructuring of energy supply is in full swing in germany. at the latest since the paris climate agreement in late 2015 energy generation from fossil fuels is no longer an option even on a world- wide scale. the same applies to the use of nuclear energy: it fails due to its high costs and risks. the rapid growth of renewable energies requires a professionaliza- tion along the entire value-added chain. Qualifjed specialists are the order of the day. rapId development of wInd energy technology the development of modern wind energy began in the 1980s in germany. Meanwhile an international industrial sector has established itself which also includes such global players as siemens and general electric. today’s machines can generate 100 times as much electricity as the earliest wind turbines.

14 | 15 challenges in renewaBle energies // windwerk – independent wind and solar farM services modern wInd turbInes requIre extensIve know-how as performance increased the demands on man and technology also rose. today the control, monitoring and maintenance of wind turbines require extensive know- how both in the area of mechanical and electrical engineering, a lot of experience and appropriate tools. in view of the high performance of modern renewable-energy power plants malfunctioning results in substantial fjnancial losses. hIgh performance large-scale solar farms even in the photovoltaics segment today’s plants can in terms of dimension and design hardly be compared to those in the 1990s when the fjrst solar plants with just a few kilowatt output were built in germany. today, both rooftop and ground-mounted plants are built in megawatt size. some ground-mounted solar farms even reach an output of several hundred megawatt. the electricity yield of a single solar park is correspondingly large – and also the fjnancial loss if inverters or module strings break down. although on the whole solar farms are less service intensive than wind farms they also require continuous performance monitoring. today wind and solar farms are important, and in future they will be the decisive power plants for the energy supply. thus, their operation increasingly requires professional management.
