Why isn't hydroelectricity used more?

Answer 1

Hydroelectricity isn't used more widely due to several factors, including environmental concerns, high initial construction costs, and geographical limitations. The construction of dams can disrupt local ecosystems and displace communities, leading to opposition from environmentalists and local populations. Additionally, suitable sites for large-scale hydroelectric plants are often limited to specific regions, making it less feasible in areas without adequate water resources. Finally, competition from other renewable energy sources, like wind and solar, which have lower upfront costs and environmental impacts, also limits the expansion of hydroelectric power.
