Which of the following are impacts of hydroelectric power plant?

A. Land-degradation

B. Micro-seismicity

C. Green House Gas Emission

D. Water Pollution

E. Smog Formation

Choose the correct answer from the options given below:

The correct answer is - Option 1: A, B, C and D Only

Key Points

• Land-degradation
  • Construction of hydroelectric power plants often requires large areas of land, leading to deforestation and disruption of natural habitats.
  • This can cause soil erosion and loss of biodiversity.
• Micro-seismicity
  • The filling of reservoirs and the pressure exerted by large volumes of water can trigger small-scale earthquakes or micro-seismic events.
• Green House Gas Emission
  • While hydroelectric power is generally considered clean, the decomposition of organic material in reservoirs can release methane and carbon dioxide—both potent greenhouse gases.
• Water Pollution
  • Hydroelectric plants can alter the natural flow and temperature of rivers, affecting aquatic ecosystems and leading to potential water quality issues.

Additional Information

• Smog Formation
  • This is typically associated with the burning of fossil fuels and industrial activities, not hydroelectric power plants.
  • Hydroelectric power plants do not contribute significantly to smog formation as they do not burn fossil fuels.
• Environmental Impact
  • Hydroelectric power plants can have significant environmental impacts, including changes to river ecosystems, displacement of local communities, and impacts on fish migration.
  • Despite these impacts, hydroelectric power is a renewable resource and can provide a significant amount of clean energy.
• Climate Change Mitigation
  • Hydroelectric power plants contribute to climate change mitigation by providing a renewable source of energy that reduces reliance on fossil fuels.
