We assess the degree of connectedness among 16 metals that are critical for the production of clean energy technologies. These commodities are the constituents of the Energy Transition Metals (ETMs) price index maintained by the International Monetary Fund and comprise base, precious, and minor...

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...

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...

What do we know about the size of the rebound effect? Should we believe claims that energy efficiency improvements lead to an increase in energy use? This paper clarifies what the rebound effect is, and provides a guide for economists and policymakers interested in its magnitude. We describe how...

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...

China’s global quest for resources, in particular oil and natural gas, has received unprecedented worldwide attention and scrutiny. This is partly because of China’s own high-profile, active energy diplomacy, its national oil companies’ acquisitions in the key exporting regions of oil and...

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...
