Plans for Expanding Nuclear Power Plants Lack Technological and Economic Foundations

In mid-April 2023, the final three nuclear power plants in Germany will be taken offline permanently. At the same time, the energy crisis resulting from the Russian invasion of Ukraine has fueled calls for the construction of new nuclear reactors in Germany. A similar debate is taking place in many other countries in the context of the climate crisis. Since the 1950s, nuclear power has been one of ...

Water Resources in Germany: Increasingly Polluted and Regionally Overused

The effects of the climate crisis are worsening water shortages, not only in the Global South but also in Europe, for example in the Berlin-Brandenburg region. Due to inadequate pricing of surface and groundwater abstraction and a lack of regulatory instruments, water overuse is occurring in some regions of Germany. Overuse is especially an issue for industry, which has contractually secured high volumes ...

From Historical Responsibility to Carbon Neutrality: A Country Classification

Ampel-Monitor Energiewende Shows the Pace of the Energy Transition Must Be Accelerated Significantly

The so-called traffic light coalition is facing a challenge: it has set ambitious energy policy targets, but can only achieve them if the pace of the energy transition is increased significantly. To contribute to the current energy policy debate, the Ampel-Monitor Energiewende (Monitor of the Traffic Light Coalition’s Energy Transition Targets) was developed at DIW Berlin. Based on open data, the Ampel-Monitor ...

Expanding Solar Energy Capacity to Power the Transition to Heat Pumps

Increasing the use of heat pumps is an important measure for reducing carbon emissions in the heating sector as well as natural gas imports. This report uses an electricity sector model to investigate the effects of an accelerated expansion of the heat pump stock on the German electricity sector in 2030. Adding around six million heat pumps would increase electricity demand by nine percent in 2030; ...

Low Emission Zones Improve Air Quality and Health but Temporarily Decrease Life Satisfaction

Air pollution results in high economic costs arising from its negative impacts on human health, especially in urban areas. Driving restriction policies such as low emission zones (LEZs) are designed to improve air quality. Indeed, empirical analyses in this Weekly Report confirm that LEZs reduce traffic-related air pollution. However, the analyses also reveal unintended adverse effects on secondary ...

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 ...

Global Economy Returning to Its Recovery Course after Summer Setbacks: DIW Economic Outlook Autumn 2021

Recently, the coronavirus pandemic has caused economic developments in major economies to drift apart: While infection rates were declining and production was experiencing strong growth in places such as Europe and the United States in the second quarter of 2021, emerging economies were experiencing strict economic restrictions due to high case numbers. In some of these countries, the economy declined. ...

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 ...

Global Economy: Advanced Economies Facing a Strong Upturn: DIW Economic Outlook Summer 2021

Global recovery is progressing more slowly than was indicated in 2020 due to high coronavirus rates and related economic restrictions in Europe and Japan. Recently, a disparate picture has been forming: In the advanced economies, declining infection rates and continued progress in vaccination campaigns will presumably lead to a revival that will be especially noticeable in the retail and service sectors ...
