Summary: Increasing concerns about greenhouse gas emissions, climate change, and resource depletion have highlighted the importance of wind energy. This study explored the potential of wind turbines in generating electricity and analyzed their energy, exergy, and economic efficiencies. The energy efficiency of the turbines ranged from 10% to 70%, with Enercon_1500 and Enercon_3050 performing better than Enercon_3500 and Enercon_2350. The highest and lowest annual total energy productions were 12.19 GWh and 4.48 GWh, respectively. Exergy efficiencies varied from 20% to 79%, and the unit electricity cost was higher for Enercon_1500 and lower for Enercon_4200.

Summary: A multigenerational waste to energy system has been developed to generate hydrogen, electricity, heating, domestic hot water, and fresh water. The system utilizes plastic waste gasification to produce syngas, which is then processed through multiple sub-systems. Energy and exergy analyses were conducted to evaluate the overall system and determine its energy and exergy efficiencies. The system also incorporates geothermal energy to generate steam for plastic waste gasification. The current system has a power capacity of 73,550 kW and produces hydrogen at a rate of 1.05 kg/s, while a reverse osmosis water desalination sub-system produces fresh water at a rate of 12 kg/s. The achieved energy efficiency and exergy efficiency for the reference case are 66.24% and 48.10%, respectively.
