2. Ambitious, achievable German targets concerning renewable
generation and energy efficiency
Basic points of the German energy transition Generation mix 2011
(energy)
> Reduction of greenhouse-gas 20 % 18 %
emissions by 40% in 2020 and by nuclear
4% lignite
80-95% in 2050 compared to 1990
coal
14 % 25 % gas
> 80% renewable generation in 2050;
others
35% in 2020
19 % renewable
> Reduction of primary energy
consumption by 20% until 2020 and by
50% until 2050 compared to 2008 Generation mix 2050
German policy target
20 % (energy)
> Reduction of emissions caused by
traffic until 2020 by 10% and until 2050

> On the last weekend of May 2012 almost half of the consumed energy in Germany
was generated by photovoltaic

> Distribution grids are mainly effected by today´s energy transition in Germany
In 2010 and 2011 there were 250.000/a new PV plants connected!

> Renewable generation causes high and fast fluctuations of residual load
> Concept for control of renewable generation necessary (partly already existing today)
> Flexible and controllable power plants (central and local) and storages needed to follow
residual load and to stabilize the system
