Question

What are the three disadvantages of developing large hydro electric power plant?

Answer 1

1. Massive Human Displacement: Creating large reservoirs floods vast regions of upstream land, causing thousands of local populations and indigenous communities to relocate and lose their homes and livelihoods.
2. Severe Ecological and Environmental Damage: Floods cause severe ecological and environmental damage, destroying local forests and wildlife habitats. Furthermore, the dam disturbs natural river flows, obstructs fish migration pathways, and may cause serious water quality issues downstream.
3. High Upfront Capital and Long Gestation Periods: Constructing huge dams necessitates massive financial investments and sometimes takes years sometimes over a decade to finish, making them high-risk financial commitments.
