Die Förderung durch das Erneuerbare-Energien-Gesetz (EEG) hat in den letzten Jahren zu einem unerwartet starken Ausbau von Anlagen zur Erzeugung von Solarstrom (Photovoltaik) geführt, weil die Systempreise der Photovoltaikanlagen schneller gesunken sind als die gesetzlich garantierten...

As building-integrated photovoltaic (PV) solutions can meet around one-third of electricity demand in Germany and China, both countries are interested in exploring this potential. PV technologies have demonstrated significant price reductions, but large-scale global application of PV requires...

Bei Einführung der ökologischen Steuerreform im Jahr 1999 wurden Unternehmen des Produzierenden Gewerbes sowie der Land- und Forstwirtschaft Vergünstigungen bei der Strom- und Energiesteuer eingeräumt. Die Bundesregierung plant, diese Vergünstigungen auch in Zukunft beizubehalten. Dazu...

Support through the German Renewable Energy Sources Act (EEG) has led, in the past few years, to an unexpectedly wide expansion of systems for generating solar power (photovoltaics) because the system prices for photovoltaic (PV) systems have fallen at a faster rate than the solar power feed-in...

In the European Emission Trading scheme the supply of allowances exceeds emissions - cumulating, according to our estimates, in a surplus of 2.7 billion tonnes by 2013/2014. We find that initially the surplus was acquired by power companies so as to hedge future carbon costs. As the surplus...

Das Erneuerbare-Energien-Gesetz (EEG) hat sich als wirkungsvolles Instrument zur Förderung von Strom aus erneuerbaren Energien erwiesen und ist in seiner Grundstruktur von einer großen Anzahl anderer Länder übernommen worden. Beim EEG besteht die Förderung insbesondere aus einer...

The building sector is a key focus area of the Energy Concept of the German Federal Government, among other reasons because it has the potential to avoid a large share of CO2 emissions while also saving costs. Thus far, however, only a small percentage of residential building owners have...

Conducting a building thermal efficiency retrofit (or further thermal retrofit) is a long and relatively complex decision-making process involving building owners, managers, residents/tenants, and construction industry professionals. A variety of information instruments exists to support...

The German government has committed to reducing the primary energy demand of buildings by 80% by 2050 and to attaining a thermal retrofit rate of 2%. Achieving both goals will require deep thermal retrofits across the existing building stock. To meet this challenge, the government is exploring...
