To reduce greenhouse gas emissions, many countries plan to massively expand wind power and solar photovoltaic capacities. These variable renewable energy sources require additional flexibility in the power sector. Both geographical balancing enabled by interconnection and electricity storage can provide such flexibility. In a 100% renewable energy scenario of twelve central European countries, we investigate ...
The future of coal remains contested in many countries, hindering necessary energy transitions. Collaborative governance approaches, such as stakeholder commissions, have been proposed as potential solution to resolve such societal conflicts. In Germany, a stakeholder commission process managed to overcome the existing stalemate situation, leading to the adoption of a coal phase-out by 2038. Celebrated ...
Energy system models are used for policy decisions and technology designs. If not carefully used, models give implausible outputs and mislead decision-making. One implausible effect is “unintended storage cycling”, which is observable as simultaneous storage charging and discharging. Methods to remove such misleading effects exist, but are computationally inefficient and sometimes ineffective. Through ...
Industrialized countries and emerging economies must cooperate in order to decarbonize the emissions-intensive industrial sector and to limit global warming to 1.5 degrees Celsius. While Germany and the other G7 countries have committed to supporting emerging economies in their efforts to combat climate change via international climate finance, it remains to be seen how this support can be implemented ...
Over the course of a decade, Mexico transitioned from a peak of 1.8% of GDP given as fuel subsidies in 2008 to generating positive fuel tax revenues equivalent to 1.6% of its GDP in 2018. This paper analyzes Mexico's carbon pricing experience: the mechanisms that made fossil fuel subsidies such a large burden on public finances, the strategies followed in its five-year phase-out, and the institutional ...
We fit CES and VES production functions to data from a numerical bottom-up optimization model of electricity supply with clean and dirty inputs. This approach allows for studying high shares of clean energy not observable today and for isolating mechanisms that impact the elasticity of substitution between clean and dirty energy. Central results show that (i) dirty inputs are not essential for production. ...
Methane is the second-largest contributor to global warming due to anthropogenic greenhouse gas emissions. Reducing anthropogenic methane emissions quickly can significantly reduce global warming within just a few decades. The oil and gas sector is responsible for almost 20% of anthropogenic methane emissions. Yet, there are hardly any policies in place that address oil and gas sector methane emissions. ...
Our analysis highlights that the current national energy and climate plans (NECPs) of EU countries are insufficient to achieve a cost-efficient pathway to EU-wide climate neutrality by 2050.
