Security of supply, affordability, and advancing towards environmental sustainability are the challenges of the energy trilemma. Balancing these three principles is complex. Therefore, governments and industries must rethink the ecological transition, as not all actions that can be taken adhere to these three rules.

Hence Naturgy's commitment to the development of renewable gas.
