Gaza has been suffering from a major crisis in the energy sector, and there is a need to adopt sustainable sources of renewable energy such as wind energy to meet the growing energy needs. This study focuses on wind energy harvesting potential as a renewable, clean source of energy in the Gaza Strip for a sustainable economy and environmental conservation. Three-blade horizontal turbines were tested with rotor diameters of 4.4, 3.8, and 3.2 m. The effect of the wind speed and the rotor diameter on the tip speed ratio (TSR), the power factor (Cp), and the turbine produced power were investigated. The result showed that annual energy of 4851.87, 3618.85, and 2566.28 kWh achieved at rotor diameters of 4.4, 3.8, and 3.2 m, respectively. The result also exposed that the total saving per year is equal to $824.8, $615.2, and $436.3 at rotor diameters of 4.4, 3.8, and 3.2 m, respectively. The payback periods of a turbine with 4.4 m rotor diameter were 8.3 years. Also, using a turbine with a rotor diameter of 4.4 m can reduce 4124 kg/yr of CO₂ emissions. It is recommended to encourage the private sector to invest in wind energy in Gaza to ensure economic growth and environmental sustainability.

小型风力涡轮机的可持续能源、经济和环境影响：一项综合研究

加沙一直遭受能源部门的重大危机，需要采用可持续的可再生能源，如风能，以满足不断增长的能源需求。本研究重点关注风能作为加沙地带可再生清洁能源的潜力，以实现可持续经济和环境保护。三叶片卧式涡轮机的转子直径分别为 4.4、3.8 和 3.2 m。研究了风速和转子直径对叶尖速比 (TSR)、功率因数 (Cp) 和涡轮产生的功率的影响。结果表明，在转子直径为 4.4、3.8 和 3.2 m 时，年发电量分别为 4851.87、3618.85 和 2566.28 kWh。结果还显示，每年的总节省等于 824.8 美元、615.2 美元和 436 美元。3 在转子直径分别为 4.4、3.8 和 3.2 m 时。转子直径为 4.4 m 的涡轮机的投资回收期为 8.3 年。此外，使用转子直径为 4.4 m 的涡轮机可以减少 4124 kg/yr 的 CO₂排放。建议鼓励私营部门在加沙投资风能，以确保经济增长和环境可持续性。
