The Russian invasion of Ukraine has refocused European energy policy on geopolitical security, accelerating the transition to clean energy sources like renewables, hydrogen, and possibly nuclear.

This paper offers a timely and relevant analysis of a complex, evolving situation. The methodology is sound, drawing on multiple sources and perspectives. While limitations exist due to the rapidly changing policy environment and the limited geographical scope, the study provides valuable insights into the multifaceted implications of the energy crisis for sustainable transformations. The analysis could have been strengthened by a more thorough investigation of social justice aspects.
