India has accelerated its energy transition by mandating 20 percent ethanol blending (E20) in petrol by 2025. This ambitious move aims to reduce fossil fuel imports, cut carbon emissions, and support India’s net zero goal by 2070. However, the policy presents multiple challenges for stakeholders including ethanol producers, vehicle manufacturers, and consumers.
Background and Policy Evolution
India’s biofuel policy initially targeted 20 percent ethanol blending by 2030. The deadline was advanced to 2025 to hasten energy security and environmental benefits. The government estimates savings of $4 billion annually in fuel imports and reductions in carbon dioxide emissions. Since 2014-15, ethanol blending has saved India ₹1.4 lakh crore in foreign exchange and reduced emissions by 736 million tonnes.
Technical and Economic Concerns
E20 fuels cause a 6-7 percent drop in fuel efficiency for four-wheelers and 3-4 percent for two-wheelers. There are also concerns about engine wear, especially corrosion of rubber and plastic parts. Vehicle buyers weigh affordability, ease of use, and maintenance costs, which may be affected by ethanol blends. Stable ethanol prices and feedstock availability, such as molasses and grains, are critical for industry viability.
Social and Environmental Implications
Ethanol production can boost farmers’ incomes and create jobs, but it depends heavily on water-intensive crops like sugarcane and paddy. In a water-scarce country, this raises sustainability questions. Diverting foodgrains for ethanol may threaten food security and increase prices, impacting vulnerable populations. There is a lack of comprehensive studies analysing social costs and benefits of ethanol production in India.
Future Demand and Food Security
India’s population is expected to reach 1.7 billion by 2050, requiring a substantial increase in food production. Current ethanol policies rely on surplus grains, but future food demands may limit this availability. Without surplus foodgrains, sustaining ethanol production could become difficult, posing risks to both energy and food security.
Impact of Emerging Technologies
New transport technologies like hydrogen fuel cells and electric vehicles (EVs) could reduce dependence on ethanol. The government’s ethanol roadmap lacks a robust assessment of these alternatives. There is a risk that ethanol infrastructure becomes obsolete, leading to stranded assets. Additionally, the disposal of vehicles incompatible with ethanol blends presents environmental challenges.
Geopolitical and Supply Chain Factors
Global events such as the Russia-Ukraine war and China’s control over rare metals affect fuel and EV supply chains. India’s reliance on Russian oil has led to US tariffs on Indian goods. These factors complicate energy planning and show the need for diversified energy strategies.
Policy and Planning Gaps
Niti Aayog’s ethanol demand estimates are conservative and based mainly on vehicle population growth. The lack of sensitivity analysis on price, demand, and supply uncertainties weakens policy robustness. An integrated assessment considering emerging technologies, consumer preferences, and economic factors is essential for sustainable ethanol policy.
Lessons from Global Experience
Brazil leads the world in ethanol fuel use, with 75 percent of light vehicles running on blends. It took Brazil nearly five decades to build this sector. India can learn from Brazil’s gradual development, policy stability, and infrastructure investments to avoid pitfalls and ensure long-term success.

Answer Hints:
1. Discuss in the light of India’s energy security, the challenges and opportunities of transitioning to ethanol-blended fuels.
- Opportunity to reduce fossil fuel imports, saving around $4 billion annually and enhancing energy security.
- E20 mandate supports India’s net zero emissions target by reducing carbon dioxide emissions .
- Challenges include lower fuel efficiency (6-7% drop in four-wheelers) and potential engine wear issues.
- Dependence on stable ethanol prices and availability of feedstock like molasses and grains is critical for industry viability.
- Infrastructure and vehicle compatibility concerns may affect adoption and maintenance costs for consumers.
- Risk of stranded assets due to future transport technologies (EVs, hydrogen) potentially reducing ethanol demand.
2. Critically examine the impact of biofuel policies on food security and water resources in developing countries with reference to India.
- Biofuel production often relies on water-intensive crops like sugarcane and paddy, stressing scarce water resources in India.
- Diverting foodgrains for ethanol can threaten food security and increase prices, adversely affecting vulnerable populations.
- India’s growing population demands increased food production, limiting surplus grains available for ethanol.
- Lack of comprehensive social cost-benefit analyses to assess long-term impacts on farmers, employment, and environment.
- Potential trade-offs between energy goals and sustainable agriculture need balanced policy interventions.
- Water and food security concerns show the need for sustainable feedstock choices and efficient water use.
3. Explain the role of emerging technologies like electric vehicles and hydrogen fuel cells in shaping the future of India’s transport sector.
- EVs and hydrogen fuel cells offer cleaner alternatives with zero tailpipe emissions, aiding decarbonisation goals.
- These technologies may reduce dependence on ethanol and fossil fuels, impacting ethanol demand projections.
- Government policies and infrastructure development for EVs and hydrogen are crucial for their widespread adoption.
- Supply chain challenges (e.g., rare metals for batteries) and geopolitical factors affect EV growth prospects.
- Lifecycle environmental and economic assessments are needed to compare these technologies with ethanol blends.
- Transition to these technologies may render ethanol infrastructure obsolete, posing asset stranding risks.
4. With suitable examples, discuss the significance of geopolitical factors in influencing India’s energy import strategies and policy decisions.
- Russia-Ukraine war disrupted global fossil fuel supplies, affecting India’s oil imports and energy security.
- India’s import of discounted Russian oil led to US-imposed tariffs on Indian goods, showing geopolitical-economic linkages.
- China’s near-monopoly on rare metals threatens supply chains for EV batteries, influencing energy transition timelines.
- Geopolitical tensions necessitate diversification of energy sources and import partners for resilience.
- Energy policies must integrate geopolitical risk assessments to ensure stable and affordable energy supply.
- Examples like Brazil’s ethanol success show how domestic energy production can reduce geopolitical vulnerabilities.
