المُلخص التنفيذي. Hydropower is a method of generating electricity that uses moving water (kinetic energy) to produce electricity. In large-scale hydropower plants the moving water drives large water turbines, and dams are needed to store water in lakes, reservoirs and rivers for later release. Stored water can be used for power ...

Large-Scale Vs. Small-Scale Hydropower For Renewable Energy
Advantages of Large-Scale Hydropower. Large-scale hydropower has several advantages such as: 1. Cost-Effective. Large-scale hydropower is considered to be one of the least expensive forms of renewable energy. Once the initial construction cost is covered, there are few maintenance costs and no fuel costs since water is the fuel used to …
