    Replacing Gas Boilers with Heat Pumps Is the Fastest Way to Cut German Gas Consumption

    The supply security of fossil gas has been disrupted by the Russo-Ukrainian War. Decisions to relocate the production and transport of gas have become so urgent that new long-term contracts are imminent that undermine the Paris Climate Agreement. Here, we simulate how quickly the addition of renewable electricity and the installation of heat pumps can substitute enough gas to reduce supply risk, while ...

    How Communication Makes the Difference between a Cartel and Tacit Collusion: A Machine Learning Approach

    This paper sheds new light on the role of communication for cartel formation. Using machine learning to evaluate free-form chat communication among firms in a laboratory experiment, we identify typical communication patterns for both explicit cartel formation and indirect attempts to collude tacitly. We document that firms are less likely to communicate explicitly about price fixing and more likely ...

    Broad Electricity Price Subsidies for Industry Are Not a Suitable Relief Instrument

    The sharp rise in electricity prices has led to a discussion on possible subsidies for companies in the form of an industrial power tariff. The subsidies should help companies remain internationally competitive and prevent them from relocating overseas. Although German electricity prices for (industrial) firms are around the European average due to many tax exemptions, they are significantly higher ...

    New Coal Mines in the Australian Galilee Basin Are Not Economically Viable and Are Prone to Become Stranded Assets

    To limit the effects of climate change, we must significantly curtail the trading and use of coal as an energy source. Although the rise of renewable energy sources has already led to a reduction in the demand for and use of coal, new export-oriented coal mine projects are still being approved, and they often receive strong political support. However, whether these projects are economically viable ...

    Green Premiums Are a Challenge and an Opportunity for Climate Policy Design: Comment

    Adjusting green public support programmes to green premiums can reduce public spending, yet this is challenged by uncertainty. Underfunding green technologies can delay the green transition, and overfunding them can increase transition costs. Both risks of under- and overfunding can be reduced using responsive adjustments.

    Sanctions against Russian Gas Would Not Endanger EU or German Gas Supply

    As a result of the Russian attack on Ukraine, natural gas prices skyrocketed in 2022 and Germany in particular felt the impact of its strong dependency on Russia. Prices have since relaxed, the European natural gas industry has overcome the uncertainty due to the energy crisis in 2022, and the industry also survived the slump in Russian natural gas imports without supply interruptions. However, Russia ...

    Electricity Markets Stabilized Following the Energy Crisis; 80 Percent Renewable Energy and Coal Phase-out by 2030 Are Possible

    The German electricity market has recovered well from the 2022 energy crisis. Policymakers should now redirect the focus of energy policy to further expanding renewable energy sources. The year 2023 showed that the German electricity supply remained secure following the shutdown of nuclear power plants. It is possible, affordable, and plausible in light of climate policy to cover 80 percent of electricity ...

    A Renewable Energy Pool Brings Benefits of Energy Transition to Consumers

    German companies view high and uncertain electricity prices a major challenge. A Renewable Energy Pool (RE-Pool), wherein the favorable conditions of competitive tenders for new wind and solar power projects are passed on to electricity consumers, could hedge such price risks. Consumers’ electricity prices are thus hedged for the share of their consumption that corresponds to the RE-Pool’s generation ...

    Sustainable Finance Taxonomies – Enabling the Transition towards Net Zero? A Transition Score for International Frameworks

    A plethora of sustainable finance taxonomies are emerging worldwide to support shifting trillions for climate action. Employing a qualitative research approach, we use document analysis to assess 26 sustainable finance taxonomy frameworks worldwide that are in the developing phase or have been published and/or adopted. Based on literature and data we build a transition score (TS) to evaluate the framework’s ...

    And Yet They Move: Energy Prices Fall When Key Interest Rates Increase, Despite Countervailing Effects

    Energy prices have risen sharply as a result of the coronavirus pandemic as well as the Russian attack on Ukraine in February 2022. The resulting consumer price inflation is forcing the European Central Bank (ECB) to act in accordance with its mandate. However, the ECB expresses doubts that it will be able to have an impact on the price increases. As this Weekly Report based on an analysis of structural ...
