Economist Luise Röpke studies the impact that the greening of Germany’s electrical system has on the grid’s reliability and cost. She says renewable energy confronts a “trilemma” – the interrelation of environmental impacts, network reliability and electricity prices. Using existing indexes and original calculations, Röpke unveils the significant economic and social costs of power outages. She explains why introducing renewable energy into the existing grid assures service deterioration unless Germany invests more money in its electrical grid network and she urges a re-evaluation of the entire national renewables program. Though this paper is burdened by techno-lingo and at least one Gordian knot of a data graph, getAbstract suggests that energy specialists and policy makers should read it, as should observers from other nations who seek lessons from Germany’s green experience.

In this summary, you will learn

  • What challenges Germany faces in pursuing green-energy programs;
  • How officials can balance the competing “trilemma” of environmental impact, electricity prices and energy reliability; and
  • What research suggests as the way forward.


Behind Germany’s Energy Initiative
Most Western governments are including provisions for the consequences of climate change in their energy-planning activities. Modern environmental concerns, now crucial to multitudes of people, add to the headaches of officials concerned with providing...
