In this study, a new application of a Tesla turbine (TT) is presented in which a TT is introduced as a promising solution to enhance the energy efficiency of refrigeration cycles. For this special purpose, a TT is represented as a regenerative system that minimizes the wasted energy without...

The paper presents results of the implementation of an efficiency strategy in Germany until 2020 which is focused on cost-effective measures. The efficiency measures are calculated in bottom-up models and translated into a top-down macro-economic model. The comparison to a business as usual...

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...

This paper explores the incentives for energy efficiency induced by the European Union Emissions Trading Scheme (EU ETS) for installations in the energy and industry sectors. Our analysis of the National Allocation Plans for 27 EU Member States for phase 2 of the EU ETS (2008-2012) suggests that...

One of the main factors in achieving the ecological development goals is the change of unsustainable consumption patterns. Households play here a crucial role. The high level of urbanization and industrialization in the Silesian Voivodeship has caused serious environmental degradation, which in...

The paper presents an empirical analysis of Carbon Footprint indicator applied to the public building of the Faculty of Chemistry at the University of Warsaw. Analysis takes into account direct and indirect CO2 emissions related to the functioning of the Faculty. Analysis concentrates on the...

The general conditions for local authorities in Germany have changed fundamentally during the last decades. Not only do municipalities compete with each other for employment, prestige and competitive advantages, they also face increasingly higher demands by their citizens, for instance in the...
