📋 Group Discussion (GD) Analysis Guide: Can Large-Scale Solar Farms Meet Global Energy Demands?
🌍 Introduction to the Topic
Context Setting: The global energy demand is projected to double by 2050, driven by population growth and rapid urbanization. Solar farms are increasingly seen as a vital solution to combat the dual challenges of climate change and fossil fuel dependence.
Background: The concept of large-scale solar farms has gained momentum due to their potential to produce vast amounts of renewable energy. Countries like China, India, and the United States are investing heavily in solar capacity, setting records in renewable energy production.
📊 Quick Facts and Key Statistics
- 🌍 Global Solar Capacity: 1,032 GW (2023), up from 760 GW in 2021, with a 15% annual growth rate.
- 💰 Cost Reduction: The cost of solar panels dropped by 85% between 2010 and 2023, making solar one of the cheapest energy sources.
- 📜 Land Use: Solar farms require 4-5 acres per MW, raising concerns about land availability and ecosystem impacts.
- ⚡ Energy Potential: A solar farm in the Sahara Desert could theoretically meet the world’s energy needs 200 times over.
- 🌱 Carbon Emissions: Solar energy systems reduce CO2 emissions by approximately 2.5 billion metric tons annually.
