Part A
Why is energy conservation important in India?
Answer
- Energy Security: India is a rapidly growing economy with a high dependence on imported fossil fuels; conservation reduces this reliance and enhances national energy security.
- Economic Efficiency: Reducing energy wastage lowers operational costs for industries and households, directly contributing to the nation's GDP growth.
- Environmental Sustainability: Conservation mitigates the carbon footprint associated with power generation, helping to combat climate change and local air pollution.
What is the relationship between Energy and Environment?
Answer
The relationship is inherently inverse regarding environmental impact. Energy production and consumption are the primary drivers of environmental degradation. Specifically:
- Resource Depletion: The extraction of fossil fuels leads to habitat destruction and biodiversity loss.
- Emission Impact: Burning fossil fuels releases greenhouse gases (CO2, CH4) and pollutants (SOx, NOx), leading to global warming and acid rain.
- Sustainability: Efficient energy management reduces the demand for raw resources, thereby minimizing the ecological footprint and preserving the environment for future generations.
