The paper considers energy consumption in 5G cellular networks powered by Renewable Energy Sources (RESs) and equipped with Reconfigurable Intelligent Surfaces (RISs) and tethered Unmanned Aerial Vehicles (UAVs), acting as mobile access points. The study was focused on the energy side of the Radio Access Network (RAN) located in the city of Pozna\'n in Poland. The profit associated with the use of renewable energy generators, i.e. photovoltaic panels (PVP) for base stations (BSs) is presented in the form of two factors: the average number of UAV charges (ANUC) to provide continuous access to mobile services for connected user equipment (UE) terminals, and the average reduction in energy consumption (AREC) of the wireless system.
