Balancing Energy Security, Green Mobility and Consumer Concerns

GS Paper III – Environment

Why in News?

India has achieved a nationwide transition towards E20 petrol, meaning petrol blended with 20% ethanol is now being supplied across the country.

What is E20 Fuel?

• E20 = Petrol containing 20% ethanol + 80% petrol
• Ethanol is a renewable biofuel produced mainly from: Sugarcane molasses , Sugarcane juice , Maize, Other agricultural residues.

Ethanol Blending Programme (EBP) - Launched by the Government of India to increase ethanol blending in petrol.

 Target: Reduce crude oil imports, Promote clean energy, Support farmers and rural economy

Significance of E20 Transition

• Reduces Import Dependence : India imports a significant share of its crude oil requirement
• Ethanol blending reduces the demand for imported petrol.
• Reduction in Carbon Emissions : Ethanol is derived from biomass and is considered a renewable fuel. Blending ethanol can reduce lifecycle greenhouse gas emissions compared to pure petrol.
• Boost to Rural Economy : Agricultural Income Support Ethanol production creates demand for: Sugarcane, Maize, Agricultural residues

Economic Impact

Positive Impacts

• Lower Oil Import Bill : Reduced petrol consumption decreases crude oil import expenditure.
• Growth of Biofuel Industry : Encourages investment in Ethanol plants, Storage facilities, Supply chains
• Farmer Benefits : Creates assured markets for ethanol feedstocks.

Negative Economic Impacts

•  Vehicle Ownership Cost :  Older vehicles may require engine modifications, Fuel system adjustments. This can increase maintenance expenses.
•  Fuel Efficiency Concerns : Ethanol has Lower energy density than petrol. Therefore Vehicles may deliver slightly lower mileage when using E20 fuel.

Environmental Concerns

• High Water Requirement: Sugarcane-based ethanol production demands large quantities of water, potentially increasing groundwater stress in water-scarce regions..
• Food vs Fuel Debate : Use of sugarcane and maize for ethanol may create competition between energy production and food security.
• Life-Cycle Emission Concerns : Ethanol’s environmental benefit depends on cultivation practices, fertiliser use, transport and processing methods.

Vehicle Compatibility Issues

• Older Vehicle Compatibility : Older petrol vehicles may face performance and maintenance issues with higher ethanol blends.
• Engine Component Damage : Ethanol can affect rubber seals, plastic parts and fuel lines in incompatible vehicles.
• Corrosion Risk : Ethanol’s moisture absorption property can increase corrosion in fuel systems.

Earth’s Silent Seismic Signals Beyond Mainshock Events

GS Paper I + GS Paper III – Physical Geography | Disaster Management

Why in News?

Maharashtra recently witnessed a cluster of shallow, low-magnitude earthquakes occurring repeatedly in a limited region.

What is an Earthquake Swarm?

An earthquake swarm is a sequence of multiple earthquakes occurring in a particular region over a short or extended period without a clearly identifiable mainshock.

Characteristics:

• Numerous small to moderate earthquakes.
• Occur in the same geographical area.
• No single earthquake dominates the sequence.
• Can continue for days, months, or even longer.

Causes of Earthquake Swarms

• Intraplate Stress : Earthquakes occurring within a tectonic plate rather than at plate boundaries.
• Ancient Fractures and Fault Zones : Old faults may remain inactive for thousands of years Stress changes can reactivate these fractures.
• Fluid Migration : Fluids enter rock fractures and reduce friction between rock surfaces, triggering earthquakes.
• Reservoir-Induced Seismicity: Large dams can trigger earthquakes due to increased crustal load, water infiltration into faults, and rising pore pressure.
• Rainfall-Triggered Seismicity: Heavy rainfall may increase groundwater pressure and lubricate fractures, causing minor seismic events.

Disaster Management Measures

• Continuous Seismic Monitoring : Use of seismographs and GPS-based crustal movement monitoring. Enables real-time tracking of seismic activity.
• Improved Seismic Zonation : Swarm data improves earthquake hazard maps. Helps develop better building codes and preparedness plans.
• Infrastructure Assessment : Conduct safety audits of high-risk structures. Promote earthquake-resistant construction and retrofitting.

• Because investors value: Environmental benefits, Sustainable investment goals, Climate-friendly projects.
• Example: Conventional Government Bond - Yield: 7% ; Green Bond - Yield: 6.8%
• If investors still prefer the green bond despite lower returns:  The 0.2% difference represents the greenium.

Why Do Investors Accept Lower Returns?

• Environmental Preferences : Many investors are increasingly preferring green assets that support renewable energy, clean transportation and climate adaptation projects.
• ESG Investing : Green bonds attract investors who consider Environmental, Social and Governance (ESG) factors while making investment decisions.
• Long-Term Sustainability Goals : Institutional investors often prioritise sustainable investment portfolios and seek to reduce exposure to climate-related risks.

What are Sovereign Green Bonds?

• Sovereign Green Bonds are government-issued debt securities through which funds are raised specifically for financing eligible environmental and climate-related projects.
• The Government of India issues sovereign green bonds as part of its borrowing programme.
• They are a debt instrument through which the government mobilises funds while committing them to green projects.

How Sovereign Green Bonds Work?

• The government issues green bonds to raise funds from investors.
• Investors purchase these securities and provide funds to the government.
• The government allocates the collected funds to approved green and sustainable projects.
• Investors receive periodic interest payments and repayment of the principal amount after maturity.
