Despite their benefits, the ecological footprint of large dams is profound. The creation of a reservoir inundates vast areas of land, leading to deforestation and the loss of biodiversity. Furthermore, dams act as physical barriers to fish migration, severely impacting species like salmon that require access to upstream spawning grounds.
Hydroelectric dams work by utilizing the potential energy of stored water. When water is released, it flows through penstocks, spinning turbines that drive generators. The efficiency of converting water potential into electricity makes hydroelectricity one of the most productive renewable energy sources globally. dams videos
