Damit die Wärmewende gelingt, gilt es, den Wärmebedarf durch energetische Modernisierungen - also bessere Dämmung, Wärmerückgewinnung und Energiemanagement - zu senken und auf klimafreundliche Heizungen umzustellen. Das nützt nicht nur dem Klima, sondern kann auch zu mehr sozialer...

Finding fuel sources to replace coal in power plants is crucial in the march toward decarbonization. Biomass and ammonia are two options offering significant potential. Both can be used with coal or alone in newly constructed facilities or in modified power plants. Relatively new power plants...

This paper identifies individual and regional risk factors for hospitalizations caused by heat within the German population over 65 years of age. Using administrative insurance claims data and a machine-learning-based regression model, we causally estimate heterogeneous heat effects and explore...

In this paper, we combine administrative data for continental Spain from 2010 to 2018 with meteorological data to identify the effect of temperature on fertility. We demonstrate that warm (25-30°C) and hot days (30°C) decrease total fertility rate (TFR) in Spain, and that the estimated...

Die Entwicklung der Erdgas- und Strompreise in Folge des russischen Überfalls auf die Ukraine sowie auch die aktuellen Beschlüsse der Bundesregierung zur Wärmewende haben die Diskussion über die Kosten der Energiewende in unterschiedliche Richtungen neu aufgelebt. Die Belastung von...

Rund 28% des jährlichen Endenergieverbrauchs in Deutschland entfällt laut der Arbeitsgemeinschaft Energiebilanzen (AGEB) auf den Sektor der privaten Haushalte. Weitere 27% der Endenergie werden vom Verkehrssektor verbraucht. Haushalte verwenden Energie insbesondere für die Erzeugung von...

This report analyses the technology status, value chain, and markets of novel thermal energy storage (TES) technologies. While most technologies currently have low technology readiness levels, they hold substantial potential for storing energy at low costs in the future. TES technologies are...

Modeling tools and technologies that will allow reaching decarbonization goals in the most cost-effective way are imperative for the transition to a climate-friendly energy system. This includes models which are able to optimize the design of energy systems with a large number of spatially...

Most empirical studies on private climate change adaptation rely on self-reported intentions which often fail to translate into real actions. Consequently, this strand of literature can only insufficiently account for the intention behavior gap (IBG) in climate change adaptation, which...

Numerical simulations of solar water heating systems using on-off control were performed for four locations in the Portuguese territory, two collector types, and a wide range of parameters. Two main design parameters were considered: the collector area and the storage volume. The relationship...

Biogas is a pervade renewable energy source in rural areas, which can be used to generate power, heating and gas to satisfy the multi-energy needs of users. This paper establishes a bi-level optimization model of integrated biogas energy system considering the thermal comfort of heat customers...
