Frequency and Duration of Low-Wind-Power Events in Germany

In the transition to a renewable energy system, the occurrence of low-wind-power events receives increasing attention. We analyze the frequency and duration of such events for onshore wind power in Germany, based on 40 years of reanalysis data and open software. We find that low-wind-power events are less frequent in winter than in summer, but the maximum duration is distributed more evenly between ...

Weder Moskau noch Washington - Deutschland braucht kein Erdgas: das beste Friedensprojekt ist die Energiewende

Fossil Natural Gas Exit – A New Narrative for the European Energy Transformation towards Decarbonization

This paper discusses the potential role of fossil natural gas (and other gases) in the process of the energy transformation in Europe on its way to complete decarbonization. Mainstream conventional wisdom has it that natural gas, perhaps in combination with other gases, should maintain an important role in the energy mix, first, as a “bridge fuel”, and then through a gradual transition toward decarbonized ...

Inform Me When It Matters: Cost Salience, Energy Consumption, and Efficiency Investments

Effective attention to information may play a prominent role in consumer choice for energy-intensive services and it may simply be a function of receiving timely information when consumption takes place. This paper investigates whether and why the timing of utility bills leads to salience bias in heat energy consumption. In Germany, the 12-month billing period varies across buildings with a significant ...

Degrees of Displacement: The Impact of Household PV Battery Prosumage on Utility Generation and Storage

Reductions in the cost of PV and batteries encourage households to invest in PV battery prosumage. We explore the implications for the rest of the power sector by applying two open-source techno-economic models to scenarios in Western Australia for the year 2030. Household PV capacity generally substitutes utility PV, but slightly less so as additional household batteries are installed. Wind power ...

An Auction Story: How Simple Bids Struggle with Uncertainty

Short-term electricity markets are key to an efficient production by generation units. We develop a two-period model to assess different bidding formats to determine for each bidding format the optimal bidding strategy of competitive generators facing price-uncertainty. We compare the results for simple bidding, block bidding and multi-part bidding. We find that even under optimal simple and block ...

Industrial Innovation: Pathways to Deep Decarbonisation of Industry: Part 3: Policy Implications

Neue Gaspipelines und Flüssiggas-Terminals sind in Europa überflüssig

Der Anfang Juli 2020 vom Bundestag beschlossene Kohleausstieg könnte eine größere Rolle für Erdgas im deutschen Energiesystem bedeuten. Doch tatsächlich ist Erdgas nicht klimafreundlicher als Kohle. Vor allem aber droht Europa bei den Erdgasimporten zum Spielfeld des Konflikts zwischen Russland und den USA zu werden. Eine Spirale aus Sanktionen und Gegensanktionen hat sich rund um den Bau der Ostseepipeline ...

The U.S. Coal Sector between Shale Gas and Renewables: Last Resort Coal Exports?

Coal consumption and production have sharply declined in recent years in the U.S., despite political support. Reasons are mostly unfavorable economic conditions for coal, including competition from natural gas and renewables in the power sector, as well as an aging coal- fired power plant fleet. The U.S. Energy Information Administration as well as most models of North American energy markets depict ...

European Green Deal: Mit ambitionierten Klimaschutzzielen und erneuerbaren Energien aus der Wirtschaftskrise

Der von der EU-Kommission angestoßene European Green Deal, ein Maßnahmenpaket zur Dekarbonisierung und nachhaltigen Wirtschaftsentwicklung, sieht Klimaneutralität in der EU bis zum Jahr 2050 vor. Um dieses Ziel zu erreichen, muss das Emissionsreduktionsziel bis 2030 (im Vergleich zu 1990) von 40 auf rund 65 Prozent erhöht werden, wie die vorliegenden Modellberechnungen zeigen. Notwendig ist dafür eine ...
