Energy transition - why?
Viewing the scarcity of fossil fuels, renewable energies will be the basis for the global economy of the future.
The study Limits to Growth, which was published in 1972 by the Club of Rome, said:
If the present growth trends in world population, industrialization, pollution, food production, and resource depletion continue unchanged,
the limits to growth on this planet will be reached sometime within the next one hundred years.1
After the oil in the 20th century caused a global economic boom, the maximum of production is foreseeable.
Faced with rising costs of developing additional reserves of coal, oil and gas the industrialized countries search for alternatives.
Nuclear energy is been seen as a pioneering technology only by a few countries
since the disaster at Chernobyl in 1986 and Fukushima in 2011. Worldwide, more electrical power from hydropower is recovered as from nuclear power.
Current electrical power supply in industrialized countries is still dominated by central large-scale power plants (plants from 50 MW).
If these are replaced in the medium and long term by many decentralized wind turbines (each up to currently 7 MW) and hydroelectric power plants,
a conversion of the networks is required - especially for the connection with offshore wind turbines.
Electricity from photovoltaics can contribute to the energy supply in some countries and requires the further development of storage technologies
in order to collect surplus energy for periods of low sunshine.
The development away from nuclear energy and fossil fuels towards renewable energies is called energy transition.
It is a historic turning point in human history.
