• Karnataka government plans to install floating solar panels on 40 lakes in Kolar, Chickballapur, and Bengaluru.
• Aims to generate 2,000 MW of renewable energy.
• Jointly implemented by Minor Irrigation and Groundwater Development Dept. and Renewable Energy Dept. Ltd.

HIGHLIGHTS

• Stated Benefits:
  • Reduced lake maintenance costs.
  • Enhanced protection against encroachment.
  • Boost to inland fisheries.
• Expert Concerns:
  • Ecological Impact:
    • May damage lake vegetation and natural aquatic life.
    • Could accelerate degradation in already stressed lakes due to urbanisation.
  • Reduced Sunlight Penetration:
    • May affect phytoplankton and zooplankton growth, harming the food chain.
  • Increased Weed Growth:
    • Accumulation of nutrients near solar structures could trigger unwanted plant growth.
• Recommendations & Alternatives:
  • Conduct pilot studies before full-scale implementation.
  • Target nutrient-rich zones to prevent algal blooms.
  • Use Category E lakes or barren lands instead of ecologically sensitive waterbodies.
  • Involve fishing communities and ensure catchment areas remain unaffected.
