Question

What is the scope of alternative sources of energy in addressing current environmental challenges?

Answer 1

1. Climate and air-quality benefits: Switching generation and transport fuels from fossil fuels to renewables cuts CO₂ and other harmful emissions, helping to address global warming and local health problems.
2. Resource and resilience benefits: Renewables conserve non‑renewable resources, enable decentralized/locally produced power, and can increase energy security and jobs.
3. Limits and tradeoffs: Many renewables have higher up‑front capital costs, depend on location or weather (intermittency), and require complementary measures (storage, grid upgrades, land‑use planning) to fully replace fossil fuels.
