The paper investigates empirically how costs per inhabitant depend on population density, considering public water and sewerage industry as example. Diverging from prior work, spatial differences in distribution costs within a German municipality are calculated for both industries by using...

We study the impact of the liberalization of EU natural gas markets on the balance of power between `local champions', customers, and outside producers. We distinguish between two steps of the reform: 1. opening access to transit pipes and 2. opening access to distribution systems, hence...

Natural gas plays an important role in the future development of electricity markets as it is the least emission intensive fossil generation option while additionally providing the needed flexibility in plant operation to deal with intermittent renewable generation. As both the electricity and...

We use the Shapley value and the nucleolus to analyze the impact of three controversial pipeline projects on the power structure in the Eurasian trade of natural gas. Two pipelines, `Nord Stream' and `South Stream', allow Russian gas to bypass transit countries, Ukraine and Belarus. The third...

Concerns about global warming and growing scarcity of fossile fuels require substantial changes in energy consumption patterns and energy systems, as targeted by many countries around the world. One key element to achieve such transformation is to increase energy efficiency of the housing stock....

The EU member states have declared to strongly increase the share of Renewable Energy Sources in the next decades. Given a large deployment of wind and solar capacities as well as limited cost-efficient storage technologies, this has two major impacts on electricity systems. First, the...

This paper analyzes the relationship between debt and the production decision of companies active in the exploration and production of oil and gas in the United States. Over the last couple of years, the development and application of innovative extraction methods, like hydraulic fracturing and...

The German government aims at a climate-neutral building stock by 2050 to reach the goals defined in the Climate Action Plan 2050. Increasing the energy efficiency of existing buildings is therefore a high priority. For this purpose, investments of private homeowners will play a major role since...
