Ten Years after Fukushima: Nuclear Energy Is Still Dangerous and Unreliable

The catastrophic accident at the Fukushima Daiichi Nuclear Power Plant on March 11, 2011, revealed unexpected safety risks of nuclear energy once again. It also accelerated the decline of nuclear energy in the international energy sector: Nuclear energy’s share of global electricity generation fell from 17 percent in 1996 to 13 percent in 2011 to approximately ten percent in 2019, with a share of primary ...

Germany's Shift from Coal Offers Lessons for Just Transition Policy

As COP26 drew to a close earlier this month, almost 200 nations agreed to “phase down” coal power in the coming years. How this is done, for coal and other fossil fuels, will have implications for individuals and communities that depend on these resources for their livelihoods.  The first case study conducted by DIW Berlin focuses on Germany and the efforts it has undertaken to support ...

Nuclear Turn: Closing Down Nuclear Power Plants Opens up Prospects for the Final Repository Site Search

With the closure of the final six nuclear power plants, the commercial use of nuclear energy for electricity generation in Germany will come to an end in 2022. Due to the German power system's sufficient capacities—in 2020, the sector exported 20 terawatt hours (TWh), or about four percent of its electricity production—and its integration into the European electricity system, there is no reason to ...

100% Renewable Energy Scenarios for North America: Spatial Distribution and Network Constraints

The urgency to combat climate change and the widely distributed, increasingly competitive renewable resources in North America are strong arguments to explore scenarios for a renewable energy supply in the region. While the current power system of North America is heavily dependent on fossil fuels, namely natural gas, coal and oil, and some nuclear power plants, some current policies at the state level, ...

The Role of Energy Storage in the Uptake of Renewable Energy: A Model Comparison Approach

The power sector needs to ensure a rapid transition towards a low-carbon energy system to avoid the dangerous consequences of greenhouse gas emissions. Storage technologies are a promising option to provide the power system with the flexibility required when intermittent renewables are present in the electricity generation mix. This paper focuses on the role of electricity storage in energy systems ...

The Economics of Variable Renewable Energy and Electricity Storage

The transformation of the electricity sector is a central element of the transition to a decarbonized economy. Conventional generators powered by fossil fuels have to be replaced by variable renewable energy (VRE) sources in combination with electricity storage and other options for providing temporal flexibility. We discuss the market dynamics of increasing VRE penetration and its integration in the ...

Renewable Energy Targets and Unintended Storage Cycling: Implications for Energy Modeling

To decarbonize the economy, many governments have set targets for the use of renewable energy sources. These are often formulated as relative shares of electricity demand or supply. Implementing respective constraints in energy models is a surprisingly delicate issue. They may cause a modeling artifact of excessive electricity storage use. We introduce this phenomenon as 'unintended storage cycling', ...

100% Renewable Energy for Germany: Coordinated Expansion Planning Needed

Due to ambitious climate change targets and other energy and industrial policy goals such as the nuclear phase-out, the energy transition in Germany is heading toward a completely renewable energy system. This Weekly Report is the first to describe scenarios for 100 percent renewable energy coverage in Germany and, furthermore, shows it is both possible and realistic. In such a scenario, no more fossil ...

Investing into Third Generation Nuclear Power Plants: Review of Recent Trends and Analysis of Future Investments Using Monte Carlo Simulation

This paper provides a review of trends in third generation nuclear power plants, and analyzes current and future nuclear power plant investments using Monte Carlo simulations of economic indicators. We first review global trends of nuclear power plant investments, including technical as well as economic trends. The review suggests that cost escalations in the sector observed in previous research continue ...

The Economics of Production, Integration and Efficient Use of Renewable Energy

Die Auseinandersetzung mit der Klimakrise bringt drei Herausforderungen bezüglich der Produktion, der Integration und der effizienten Nutzung von Energie mit sich. Diese Herausforderungen werden in den drei Kapiteln dieser Dissertation analysiert. Erstens wird Energieeffizienz weithin sowohl als ein effektives Mittel zur Reduzierung des Verbrauchs fossiler Energien als auch als kosteneffiziente Lösung ...
