When the tsunami hit the Fukushima atomic plant in Japan inMarch 2011, causing the reactor disaster, it was impossible to predict the consequences for the future of energy supply.Many countries have considerably strengthened their activities since then to realize an energy turnaround, i.e., a switch from nuclear power and fossil fuels to a more sustainable energy supply with increased use of regenerative energy resources such as wind or sun. Whereas only 55 states had political ambitions to expand the use of renewable energies in 2005, this number has increased to about 190 states in 2012. Also a change in attitudes can be observed. Early in 2012, more than 70 % of the French supported a phase-out of nuclear power \u2013 even though France was worldwide frontrunner in this area with a 75 % nuclear powered energy supply in the end of 2010. Germany takes an uncompromising approach in that it has officially decided to phase out nuclear power completely by 2022, although the economically strong parts in the country\u2019s south receive more than 50 % of their electricity from nuclear power plants. This development towards a nuclear phase-out, which can be observed in other countries to a lesser extent, can be considered \u2013 in the jargon of BISE \u2013 as a revolution more than an evolution. A revolution always comes with risks, but also offers opportunities. In the following we will show that the energy turnaround opens up a wide range of opportunities \u2013 if it is addressed responsibly and with a well-conceived plan.<\/p>\n
