Urban areas are critical in accomplishing the clean energy transition and meeting the climate goals in the Paris Agreement.
As large renewable capacities penetrate the European energy system and the climate faces significant alterations, the future operation of hydropower reservoirs might deviate from today.

Renewable Energy Systems

Modelling, Optimization and Control, Advances in Nonlinear Dynamics and Chaos (ANDC), 2021, Pages 687-705

This book chapter addresses SDG 7 by explaining how a stand-alone solar PV/wind hybrid system works including necessary controlling and modeling.
The review examined the potential of renewable and non-renewable energy resources and the current state of exploitation in Kenya.
Heating and cooling in buildings account for nearly 20% of energy use globally.

Energy Policy, Volume 155, August 2021

Nuclear power's contribution to climate change mitigation is and will be very limited. Currently nuclear power avoids 2–3% of total global GHG emissions per year. According to current planning this value will decrease even further until 2040. A substantial expansion of nuclear power will not be possible. Given its low contribution, a complete phase-out of nuclear energy is feasible.
Many inhabited Greek/Mediterranean islands are unsustainable without mainland support due to lack of access to clean water and energy. This case study establishes the feasibility of sustainable green energy solutions for these settlements.
This paper provides a methodology for the holistic analysis of hybrid renewable energy systems in rural communities. 

Electrification, Accelerating the Energy Transition, 2021, Pages 3-24

This book chapter advances SDG 7 by introducing electrification as a megatrend directly shaping not only the energy system but also society, global development, and energy politics internationally. In particular, it highlights the potential for electrification as a master solution for an accelerated transition to climate neutrality
