Der Beitrag skizziert zunächst die gegenwärtigen Herausforderungen an das globale Energiesystem und stellt das vorhandene Wissen zu energieeffizienten Lösungen in allen Sektoren dar. Dabei geht es nicht nur um die Umwandlung von Primär- in Nutzenergie, sondern - wichtiger noch - von Nutzenergie in Energiedienstleistungen (Materialeffizienz und Substitution). Bei der Analyse der Effizienzpotentiale ...
Energy is an important commodity in many economic activities. Its usage affects the environment via CO2 emissions and the Greenhouse Effect. Modeling the energy-economy-environment-trade linkages is an important objective in applied economic policy analysis. Previously, however, the modeling of these linkages in GTAP has been incomplete. This is because energy substitution, a key factor in this chain ...
The main aim of this paper is to investigate quantitatively the economic impacts of emissions stabilization scenarios with and without the inclusion of induced technological change (ITC). Improved technological innovations are triggered by increased research and development (R&D) expenditures that advance energy efficiencies. Model results show that ITCs due to increased investment in R&D reduce compliance ...
This paper applies the literature on asymmetric price transmission to the emerging commodity market for EU emissions allowances (EUA). We utilize an error correction model and an autoregressive distributed lag model to measure the relationship between CO2 price changes and the development of wholesale electricity prices. Using data from the German market for electricity and EUAs, we find that the rising ...
Seeking to play a pioneering role in climate protection, the European Union has decided to pursue a reduction of at least 20% in greenhouse-gas emissions (on 1990 levels) by the year 2020. Moreover, Europe has declared its willingness to commit itself to emission reductions of 30% over the same period if other developed countries commit themselves to similar targets and if developing countries also ...
Emerging nations are typically characterised by highenergy intensities despite significant energy efficiency potentials and numerous project oriented efforts to introduce energy-efficient technologies. The paper argues that successful technology dissemination needs appropriate institutional structures to reduce the related transaction cost. While a project-by-project approach risks to evaporate after ...
In this article, we analyse the effects of emissions trading in Europe, with special reference to Germany. We look at the value of the flexibility gained by trading compared to fixed quotas. The analysis is undertaken with a modified version of the GTAP-E model using the latest GTAP version 6 database. It is based on the national allocation plans (NAP) as submitted to and approved by the EU. We find ...
