Cold and heat waves represent a significant problem for the electricity generation sector. The disruptions cold and heat waves can cause in power production are beyond their consumption impacts through, for instance, higher peak demand. Unexpected stops at thermal or nuclear power plants by excessively high-temperature water constitute clear examples of this. In this invited paper, we use past case studies to analyze the impact of these kinds of events on power production. Subsequently we discuss how events of this nature may evolve over the future in view of their association to climate change. Although the review is not exhaustive, we do expose some ideas that may be relevant for decision making in this area

The great recession brought an increased need for public revenues and generated distributive concerns across many countries. This has led to a new generation of green tax reforms characterized by the use of markedly heterogeneous proposals that, overall, share a more flexible use of tax receipts adapted to the new economic environment. This article explores the possibilities of implementing this new generation of green tax reforms in Spain. It analyzes the impact of such reforms on energy demand, emissions, public revenues and income distribution from taxing various energy-related environmental damages and by considering two alternative uses for the tax receipts: fiscal consolidation and funding the costs of renewable-energy support schemes.
