Due to their stationary nature and limited exposure to international competition, electricity sectors are frequently called upon to generate a major share of these emissions reductions. Beyond reductions in absolute consumption, this means substituting fossil-fuel based power generation with low-carbon technologies such as renewables or nuclear power. For instance, the Energy Roadmap of the European Commission (EC) envisions greenhouse gas emissions in 2050 to be at least 80% lower than in 1990, while the electricity sector is supposed to be carbon-neutral by that date (EC, 2011a).
