In the summer semester lecture Energy and Climate Change focuses on teaching the fundamentals of climate physics, key elements of sustainable energy system transformations and related policy processes.

In winter semesters, students will develop their own small energy systems model in the seminar Energy Systems Modeling.

Summer Semester: Energy and Climate Change

Time: Monday 2:15 pm - 3:45 pm; the course starts on 17 April 2023.

Location: The lecture will be held in room C 230 at TU Berlin.

Language: The lecture will be held in English.

Objective: The overall objective of the lecture to equip students with the systemic understanding to evaluate energy technologies, business planning and energy policies in the context of the climate change mitigation challenge. Students will acquire a basic understanding of the fundamentals of climate physics, key elements sustainable energy system transformations and related policy processes.

Target audience: The lecture addresses masters students and graduate students with a background in engineering (in particular energy and process engineering, environmental engineering), natural science or economy. Basic knowledge of energy systems is an asset. No further formal requirements.

Examination: Final written or oral exam.

Registration: Registration is required via ISIS. If you have any questions, please contact .

Credits: 3 Leistungspunkte

Topics covered:  The lectures will cover the following topics

  • Introduction and overview
  • Climate physics
  • Energy systems transformation: The big picture
  • Decarbonization of energy demands in the industry, transportation, and buildings sectors
  • Bioenergy, carbon dioxide and negative emissions
  • Renewable energy integration and sector coupling
  • Climate change, air pollution and other environmental impacts of energy
  • The economics of climate change
  • International climate policy
  • European policy and the German Energiewende
  • Wrap up and final exam

Winter Semester: Energy Systems Modeling

Time: 1-week block seminar from 28 February - 4 March 2022. 

Location: Due to the Covid-19 crisis, the lecture will be held remotely via zoom conference.
                 Zoom Link will be shared via ISIS.

Language: The lecture will be held in English

Objective: By the end of the course successful students will have

  • Acquired a basic understanding of the functioning of energy system models;
  • Built up their own simple energy systems model;
  • Applied the model to a specific use case, e.g. CO2 emission reductions;
  • Analyzed model results;
  • Learned to interpret the results of energy models and acknowledge limitations.

Target audience: The lecture addresses masters students and graduate students with a background in engineering, natural science or economy. Basic experience in programming is essential. Further, Students should have basic knowledge of and interest in energy systems. No further formal requirements.

Examination: Presentation

Registration: Registration is required via ISIS until 31 December 2021. If you have any questions, please contact .
