Important announcement

Dear visitor,

Please note that this OpenCourseWare platform will be replaced at the end of 2026 by a new platform (under the same url ocw.tudelft.nl).

Courses and their contents that are currently available the platform will partly be migrated. URL’s for this content will change and content might be unavailable for some time. In addition, some courses will not be available anymore.

If you are linking to specific courses on this platform (for instance for your students), please take timely measures to avoid problems with access. Possible actions are:

  • Download the materials to your local platform (laptop, server)
  • For educators only (including TU Delft lecturers): Contact us at ocw@tudelft.nl and inform us what course you are using in what context (institute, program, period of use, number of students). We will research (in collaboration with the authors of the course) and decide if we will migrate the course, and if yes, can supply you with a new url.

Thank you.

4.1.1 What is energy efficiency?

Course subject(s) 4. Towards climate neutral energy systems

Welcome to the first video of module 4. To start this module we will be looking the concept of efficiency and what it means in the context of the energy transition. As you will see energy efficiency improvements have, and will continue to have, an important role in reducing energy consumption.

Examples of the different types energy efficiency improvements and what role they play in each sector

Key takeaways:

  • Energy efficiency improvements have an important role to play in the energy transition
  • Specific energy consumption is the energy use required to produce a unit of activity, for example MJ of energy per tonne of steel produced
  • The energy efficiency improvement for a particular activity is simply the reduction in specific energy consumption of that activity
  • Energy efficiency improvements can be realised by: reducing losses, recovering energy or through more efficient conversion
