In Germany, substantial drops in wholesale power prices have become a regular phenomenon. While such price drops have far-reaching implications for the functioning of the power market, their underlying determinants remain poorly understood. To fill this gap, we propose a Markov regime-switching...

This paper presents evidence that the accumulating cost of Germany’s ambitious plan to transform its system of energy provision – the so-called Energiewende – is butting up against consumers’ willingness-to-pay (WTP) for it. Following a descriptive presentation that traces the German...

The quest for a European energy policy has been at the heart of the European integration since World War II. Since the aftermaths of the two oil shocks, all attempts to create a Common Energy Policy failed so far. The paper seeks to identify why Europe needs to define a coherent and ambitious...

The paper first outlines the challenges the global energy system is facing. It then summarises the present knowledge of energy efficient solutions in all energy using sectors from primary energy to useful energy and, more importantly, from useful energy to energy services (material efficiency...

We compare a range of energy efficiency policies in a durable good market subject to both energy-use externalities and price-quality discrimination by a monopolist. We find that the social optimum can be achieved with differentiated subsidies. With ad valorem subsidies, the subsidization of the...

In addition to the already present Climate and Energy package, the European Union (EU) plans to include a binding target to reduce energy consumption. We analyze the rationales the EU invokes to justify such an overlapping and develop a minimal common framework to study interactions arising from...

This paper evaluates an intervention that randomized information letters about energy efficient investments and behaviors among 120,000 customers of two utilities in Germany. We find that conservation effects differ considerably between both utilities, ranging from a precisely estimated zero...

The seminal studies by Allcott and Mullainathan (2010), Allcott (2011), and Allcott and Rogers (2014) suggest that social comparison-based home energy reports (HER) are a cost-effective non-price intervention to stimulate energy conservation. The present paper demonstrates the context-dependency...

Energy efficiency is one of the key crossroads between energy, climate and economic issues. In fact, it represents one of the most cost effective ways to enhance security of energy supply, to reduce emissions of greenhouse gases and to enhance economic competitiveness at one fell swoop. This...

The Russian-Ukrainian crisis has revitalized the European concerns of supply disruptions of natural gas as experienced in 2006 and 2009. However, the European supply situation, regulation and infrastructure have changed since: imports are more diversified, EU member states better connected and a...
