GS Paper III: Economy
Context: India has successfully achieved the nationwide rollout of E20 fuel (20% ethanol blended petrol) ahead of its original target, making ethanol blending a key component of the country’s energy transition strategy.
- However, the policy has generated debate regarding its economic viability, environmental sustainability, impact on agriculture, and consumer welfare, particularly in the context of falling international crude oil prices
Background
- Ethanol is a renewable biofuel produced from sugarcane juice, damaged food grains, maize, and other biomass feedstocks.
- Under the National Policy on Biofuels, 2018, India accelerated its target of achieving 20% ethanol blending (E20) from 2030 to 2025, which has now been accomplished.
- Ethanol is blended with petrol to reduce dependence on imported fossil fuels and promote cleaner transportation.

Objectives of Ethanol Blending
- Enhance Energy Security
- India imports nearly 85% of its crude oil requirement.
- Greater ethanol blending reduces dependence on imported crude oil and strengthens energy security.
- Reduce Carbon Emissions
- Ethanol is considered a cleaner-burning renewable fuel.
- Blending ethanol with petrol lowers greenhouse gas emissions and supports India’s climate commitments.
- Increase Farmers’ Income
- Greater demand for agricultural feedstocks such as sugarcane, maize, and damaged grains is expected to provide additional market opportunities for farmers.
Advantages of Ethanol Blending
- Reduces Crude Oil Imports: Lower dependence on imported petroleum products improves India’s balance of payments and reduces vulnerability to global oil price shocks.
- Promotes Renewable Energy: Ethanol contributes to India’s transition towards clean and renewable energy sources, supporting sustainable development.
- Generates Rural Economic Activity: Expansion of ethanol production creates opportunities for biofuel industries, rural employment, and agricultural value chains.
- Supports Climate Goals: Reduced fossil fuel consumption contributes towards achieving India’s Nationally Determined Contributions (NDCs) under the Paris Agreement.
Major Concerns and Challenges
Economic Challenges
1. Ethanol-Blended Fuel May Become Costlier
- When international crude oil prices remain below approximately US$70 per barrel, ethanol-blended petrol may become more expensive than conventional petrol.
- In such situations, consumers may not receive the benefits of lower global crude prices.
2. Benefits Do Not Fully Reach Farmers
- The policy assumes that higher ethanol demand increases farmers’ incomes.
- However, a significant share of the economic gains accrues to sugar mills and ethanol distilleries, while farmers often receive only limited additional benefits.
Technological Challenges
Compatibility Issues with Older Vehicles
- Many vehicles manufactured before the introduction of E20-compatible engines may experience engine wear, component deterioration, and reduced fuel efficiency.
- Although further scientific verification is required, such concerns have been widely reported by consumers.
Agricultural and Environmental Challenges
- High Water Consumption
- Sugarcane, the primary feedstock for ethanol production, is an extremely water-intensive crop.
- Expanding sugarcane cultivation increases pressure on India’s already stressed groundwater resources.
- Promotion of Unsustainable Cropping Patterns: The ethanol policy encourages cultivation of water-intensive crops even in drought-prone regions, aggravating regional water scarcity.
- Soil Degradation: Continuous cultivation of sugarcane leads to monoculture, excessive fertilizer use, and gradual deterioration of soil fertility.

Food Security Concerns
- Food versus Fuel Dilemma
- Diverting food crops towards fuel production raises ethical and developmental concerns in a country where food insecurity and malnutrition continue to exist.
- The diversion of edible agricultural produce for biofuel production may affect long-term food security.
- Agricultural Income Concerns
Ethanol Alone Cannot Double Farmers’ Income
- The major reasons for low farm incomes include post-harvest losses, limited market access, and distress sales.
- Ethanol blending does not directly address these structural problems affecting Indian agriculture.
Suggested Reforms
- Promote Second-Generation (2G) Ethanol
- Greater emphasis should be placed on 2G ethanol, which is produced from non-food biomass such as:
- Crop residues
- Rice straw
- Wheat straw
- Groundnut shells
- This approach reduces the food-versus-fuel conflict while also addressing stubble burning and air pollution.
- Increase Investment in Research and Development: The Government should support research, technology development, and capital subsidies to reduce the cost of 2G ethanol production, which is currently expensive.
- Adopt Resource-Efficient Feedstocks: Ethanol production should gradually shift towards less water-intensive crops and agricultural residues to improve resource-use efficiency.
- Address Structural Problems in Agriculture
- Government interventions should focus on:
- Reducing post-harvest losses
- Improving market access
- Strengthening agricultural supply chains
- Ensuring better price realization for farmers
- These reforms are more effective in increasing farm income than relying solely on ethanol demand.
- Introduce Flexible Blending Policies
- The ethanol blending ratio should be periodically reviewed in light of international crude oil prices, domestic feedstock availability, and consumer interests.
- A flexible approach can balance energy security, economic efficiency, and consumer welfare.

Conclusion
- Ethanol blending is an important pillar of India’s strategy to enhance energy security, reduce carbon emissions, and promote renewable fuels. However, the long-term sustainability of the programme depends on balancing economic efficiency, consumer interests, water conservation, and food security.
