Lecture: Energy and Climate Change

Summer Semester 2020

Time: Monday 14:15-15:45, starting 20 April 2020.
Location: Due to the Covid-19 crisis, the lecture will be held remotely via zoom conference.
                Zoom Link will be shared via email

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 until April 15th, 2020
via email to Dorothee Keppler                           

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
