Combined heat and power (CHP) can achieve fuel efficiencies of up to 90% and is thus considered as economically advantageous and ecologically sound compared to uncoupled power and heat generation. This advantage is exploited only if CHP plants are operated as much as possible at their optimal operation point. Increasing penetration by variable renewable energy sources and more flexible technologies ...
Policymakers have implemented a wide range of non-pharmaceutical interventions to fight the spread of COVID-19. Variation in policies across jurisdictions and over time strongly suggests a difference-in-differences (DD) research design to estimate causal effects of counter-COVID measures. We discuss threats to the validity of these DD designs and make recommendations about how researchers can avoid ...

Drawing on data from the Socio-economic Panel (SOEP) for 2018, we use a sample of 2,145 heterosexual couples with children below age 13 to investigate the paternal involvement in domestic childcare and the relation of the underlying mechanisms to the two job-related “Covid-19 factors” systemic relevance (SR) and capacity to work from home (WfH). Based on bi- and trivariate analyses of the intra-couple ...

However, natural gas has no climate benefit compared to coal. What is more, Europe risks to become a battleground for the conflict between Russia and the United States. The construction of the Baltic Sea pipeline Nordstream 2 has set in motion a downward...
