Wind Power vs. Hydropower: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Wind power harnesses air currents to generate electricity, while hydropower uses flowing water for energy production.
Key Differences
Wind power is generated by converting the kinetic energy of wind into electricity using wind turbines. Hydropower, in contrast, relies on the movement of water, typically in rivers or dams, to produce electricity through turbines.
