Roadmap for Answer Writing
1. Introduction
- Define natural gas and its role in energy systems.
- Briefly state India’s energy transition goals, including the aim to achieve net-zero emissions by 2070 and the plan to increase natural gas’s share in the energy mix from 6.6% to 15% by 2030.
2. Body
I. Role of Natural Gas in Bridging India’s Energy Transition
- Short-term Energy Transition:
- Acts as a cleaner alternative to coal, with coal-to-gas switching reducing emissions by 50%.
- Supports emissions reduction during the ramp-up of renewable energy capacity.
- Fact: Natural gas currently constitutes 6.6% of India’s energy mix but is targeted to rise to 15% by 2030.
- Grid Stability and Backup for Renewables:
- Provides reliable energy during periods of intermittency in solar and wind power.
- Balances demand fluctuations to stabilize the grid.
- Industrial and Transportation Transition:
- Replaces coal in industrial processes, lowering emissions in sectors like manufacturing and refining.
- Supports the transition to hydrogen energy, as natural gas is a key input in hydrogen production.
II. Challenges in Natural Gas Adoption
- High Import Dependence:
- India imports over 50% of its natural gas as LNG, making it vulnerable to price volatility.
- Fact: Global infrastructure and price disparities hinder India’s ability to secure low-cost natural gas.
- High Infrastructure and Regulatory Costs:
- Significant upfront costs for LNG terminals, pipelines, and regasification plants.
- A steep and varied taxation regime across states.
- Emerging Alternatives:
- Biogas and compressed biogas (CBG) are cleaner, renewable alternatives gaining traction.
- Fact: CBG can replace compressed natural gas (CNG) in vehicles, reducing dependency on fossil-based fuels.
III. Opportunities and Strategies
- Invest in LNG infrastructure and reduce regulatory bottlenecks.
- Promote technology for biogas and hydrogen production alongside natural gas adoption.
- Leverage public-private partnerships to scale up natural gas access and usage.
3. Conclusion
- Reiterate that natural gas can act as a transitional bridge fuel, addressing energy reliability and emissions reduction in the short to medium term.
- Emphasize the need for complementary investments in renewables and sustainable energy alternatives for long-term energy security and climate goals.
Relevant Facts
- Emission Reduction: Coal-to-gas switching reduces emissions by 50% .
- Import Dependency: India relies on imports for over 50% of its natural gas deman.
- Hydrogen Production: Natural gas is a major input for hydrogen, which is critical for heavy transportation decarbonization .
This roadmap ensures a balanced and comprehensive answer structure while integrating relevant facts for analytical depth.

Over the next 20 years, climate change will likely impact the food we eat in several ways. Rising temperatures, changing rainfall patterns, and more extreme weather events could reduce crop yields, affecting the availability of staples like wheat, rice, and maize. Increased CO₂ levels might also lower the nutritional quality of these crops, reducing essential nutrients.
Climate change can expand the range of pests and diseases, leading to higher crop losses and increased costs for managing these issues. Water shortages from altered precipitation and higher evaporation rates may impact irrigation, further affecting food production.
Food prices may rise due to reduced crop yields and higher production costs, making food less affordable, especially for low-income populations. Seafood availability could be affected as changing ocean conditions impact marine ecosystems and fish populations.
Overall, climate change could lead to increased food insecurity by disrupting production and supply chains. Adapting to these challenges will involve developing resilient crops, improving water management, and adopting sustainable farming practices to ensure a stable food supply.
