This paper aims to analyze what happens with renewable energy power plants, such as onshore wind, photovoltaics and biomass, when the public policy support based on the Renewable Energy Law expires. With its expiration the first renewable energy (and especially onshore wind) power plants will...

This study is based on the recent development of the European energy environment, which experiences a transition from being dominated by conventional energy generation into an increased penetration of renewable energy sources. Today's system operators offer a set of ancillary services, such as...

The future transformation of the energy system is a contentious topic, involving a variety of conflicting opinions and interests. In order to structure and evaluate these opinions, we develop a group decision-making process with professional stakeholders and energy experts. The aim of this...

In this paper, we identify key drivers and barriers for the adoption of building energy retro fits in Germany, which is promoted by public policy as an important measure to address the future challenges of climate change and energy security. We analyze data from a 2009 survey of more than 400...

We analyze the significance of an ice-free Northeast Passage (NEP) as a shipping route for LNG, and the impacts on alternative transport routes and -capacities. The following aspects are considered: (1) Trends in LNG production, particularly in the Russian Arctic; (2) Developments in the Asian...

We examine the relevance of an ice-free Northeast Passage as a shipping route, especially for LNG-supplying and -consuming countries. Four aspects are considered in-depth: (1) Developments in natural gas production in the Russian Arctic; (2) Trends and strategies of major Asian LNG-consuming...
