Applying Energy Efficiency provides a comprehensive overview of technical and economic aspects of energy efficiency measures. The online training presents support mechanisms for energy efficiency projects and points out saving potentials in the industrial sector as well as in the built environment. Organisational aspects, such as energy management systems and energy audits, are also covered.


  • Introduction to energy efficiency projects
  • Support mechanisms for energy efficiency projects
  • Systematic approaches to energy saving
  • Energy efficiency in the industry
  • Energy efficient buildings

Live virtual classrooms (webinars):

  • Technological aspects of energy efficiency
  • Cross-sectional energy efficiency technologies

Each participant will have access to short introductory courses on energy and electricity topics to learn or revise the basics. These courses are not mandatory, and will not be covered in the exam.

Lars Koerner, RENAC

Current position:

Lars Koerner is the head of the Solar Energy/Energy Efficiency/Rural Electrification department at Renewables Academy (RENAC) AG. Lars joined RENAC in 2014. Throughout his time there, he has coordinated and conducted international training sessions and train-the-trainer programmes primarily in the field of solar energy systems. He has also designed, equipped, and installed several training centres. He specialises in off-grid systems and PV-Diesel-Hybrid system (mini-grids) for rural electrification or C&I applications.

Professional experience:
Before joining RENAC, Lars gained several years of experience as project engineer and senior product manager at SolarWorld AG. There he engineered and managed several rural electrification projects. His experience in the area of solar energy spans further through his work at the German Aerospace Center (DLR) in Almeria, Spain and at Fraunhofer ISE in Freiburg, Germany. He is an expert in sizing and simulation of solar energy systems as well as the co-author of the off-grid systems chapter in Planning and installing photovoltaic systems: a guide for installers, architects and engineers (Deutsche Gesellschaft für Sonnenenergie (DGS), 2013).

Lars holds an engineering diploma in Environmental Engineering / Renewable Energies and is also a state-licensed electrician.


"My overall experience with RENAC was a pleasant one. The material was provided in a cohesive manner on a platform that was easy to interact with. I was able to relate the material to my professional field. I will be able to use what I have learnt to improve the work that I do."
Quanley Marieatte, Applying Energy Efficiency, 2020

"Applying Energy Efficiency gives a complete picture of the policy, managerial and technical aspects of planning and application of the energy efficiency in a holistic manner; at both the national and sectoral levels."
Hossein Khajehpour, TU Berlin, Applying Energy Efficiency, 2018
