Energy Conservation Measures
At the global level, climate action today is no longer limited to clean energy production; it equally emphasises how we consume energy.
The cover decision of COP-27, titled the Sharm el-Sheikh Implementation Plan, highlights the transition to sustainable lifestyles and sustainable patterns of consumption and production as a core requirement for addressing climate change.
👉 This clearly places energy conservation at the heart of climate governance.
Energy Conservation Act, 2001
Purpose and Scope
The Energy Conservation Act (ECA), 2001 provides India’s legal and regulatory framework for:
- Regulating energy consumption
- Promoting energy efficiency
- Encouraging energy conservation
It applies to:
- Appliances and equipment
- Vehicles
- Industrial and commercial establishments
- Buildings
Both Central and State governments are empowered to implement energy-efficiency measures under this Act.
Five Core Provisions of the ECA, 2001
- Designated Consumers
- Standards and Labelling of Appliances
- Energy Conservation Building Codes (ECBC)
- Creation of the Bureau of Energy Efficiency (BEE)
- Establishment of Energy Conservation Fund
Energy Conservation (Amendment) Act, 2010
- Empowered the Central Government to issue Energy Savings Certificates.
- These certificates are awarded to designated consumers whose energy consumption is below prescribed norms.
👉 This laid the foundation for market-based energy efficiency mechanisms.
Bureau of Energy Efficiency (BEE)
- Bureau of Energy Efficiency is a statutory body under the Ministry of Power.
- Established in 2002 under the provisions of the Energy Conservation Act, 2001.
Functions of BEE
- Develop and implement programmes for efficient use of energy
- Promote energy conservation across sectors
- Mandate star labelling for selected appliances
👉 NOTE: BEE is the nodal institution for India’s energy efficiency mission.
Energy Conservation Building Code (ECBC)
- Launched in 2007 by the Ministry of Power.
- Prescribes minimum energy performance standards for:
- Commercial buildings
- Connected load ≥ 100 kW or contract demand ≥ 120 kVA
- Implementation is voluntary, but many states have adopted it.
ECO Niwas Samhita, 2018
- Also known as Energy Conservation Building Code for Residential Buildings (ECBCR).
- Launched by the Ministry of Power.
Objective
- Promote energy-efficient design and construction of → Homes, Apartments, Townships
👉 Focuses on occupant comfort, reduced energy bills, and lower environmental impact.
Standards & Labelling Programme (BEE Star Label)
- Initiated by BEE in 2006.
- Provides consumers with information on electricity consumption under standard conditions.
- Enables informed choice and long-term cost savings.
Coverage
- 23 appliances/equipment
- 10 mandatory
- 13 voluntary
Mandatory Appliances like:
- Room Air Conditioners (including inverter and commercial ACs)
- Refrigerators (frost-free and direct cool)
- LED lamps
- Electric geysers
- Distribution transformers
- Colour televisions
Voluntary Appliances like:
- Ceiling fans
- Washing machines
- LPG stoves
- Laptops
- Diesel generators
- Chillers
- Microwave ovens
Chiller Star Labelling Programme
- Launched by the Ministry of Power
- Formulated by BEE
Why Chillers Matter?
- Chillers account for over 40% of total energy consumption in commercial buildings.
- Widely used in:
- Large buildings
- Industrial cooling
- Central HVAC systems
Objective
- Promote energy-efficient chiller systems
- Encourage advanced HVAC technologies
- Reduce electricity consumption in large commercial and industrial setups
UJALA and SLNP Programmes
- Implemented by Energy Efficiency Services Limited (EESL), a PSU joint venture under the Ministry of Power.
LED Street Lighting National Programme (SLNP)
- World’s largest streetlight replacement programme
- Over 1.03 crore smart LED streetlights installed
- Annual GHG reduction: 4.80 million tCO₂
UJALA (Unnat Jyoti by Affordable LEDs for All)
- World’s largest domestic lighting programme
- Over 36.13 crore LED bulbs distributed
- Annual GHG reduction: 38 million tCO₂
👉 These schemes show how simple efficiency measures can yield massive climate benefits.
New Energy Performance Standards for Air Conditioners
24°C Default Setting
- Mandatory from 1 January 2020 for all BEE-rated Room Air Conditioners.
Benefits
- By 2030, ACs could account for 200 GW of connected load.
- Every 1°C increase in thermostat setting saves 6% electricity.
- 24°C default alone can save 20 billion units annually.
👉 Also improves human comfort and health, as excessive cooling is physiologically unhealthy.
Indian Seasonal Energy Efficiency Ratio (ISEER)
- Earlier system: Energy Efficiency Ratio (EER)
- New system: ISEER (from January 2018)
Why ISEER?
- Accounts for seasonal temperature variations in India.
- Defined as:
ISEER = Cooling Seasonal Total Load (CSTL) / Cooling Seasonal Energy Consumption (CSEC)
👉 Makes AC star ratings more realistic and India-specific.
Sustainable Energy for All (SE4All)
- A global multi-stakeholder partnership launched in 2011 by the UN Secretary-General.
- Supports SDG-7 and the Paris Agreement.
Three Interlinked Objectives (by 2030)
- Double the rate of improvement in energy efficiency
- Double the share of renewable energy
- Ensure universal access to modern energy services
Energy Conservation (Amendment) Bill, 2022
- Passed by Rajya Sabha
- Amends the Energy Conservation Act, 2001
Objectives
- Achieve revised India’s NDCs adopted at COP-26 (Glasgow)
- Mandate use of non-fossil energy sources
- Establish carbon markets in India
Key Provisions
1. Mandatory Use of Non-Fossil Energy
- Central Government can mandate minimum non-fossil energy use for designated consumers.
Designated consumers include:
- Energy-intensive industries (steel, cement, chemicals, mining)
- Transport sector (including Railways)
- Commercial buildings
2. Carbon Trading
- Government or authorised agency can issue carbon credit certificates.
- Certificates are tradeable.
- Voluntary participation also allowed.
👉 Carbon credit = tradeable permit to emit a specified amount of carbon.
3. Energy Conservation & Sustainable Building Code
- Replaces ECBC with a broader code covering:
- Energy efficiency
- Renewable energy use
- Green building norms
4. Applicability to Residential Buildings
- Code now applies to: Commercial, Office, Residential buildings (meeting load thresholds)
- States empowered to lower thresholds.
5. Standards for Vehicles and Vessels
- Energy efficiency norms extended to:
- Vehicles (Motor Vehicles Act, 1988)
- Ships and boats
- Non-compliance attracts penalties.
6. Enhanced Role of SERCs
- State Electricity Regulatory Commissions can:
- Adjudicate penalties
- Frame regulations to discharge their functions
7. Strengthening BEE
- Governing Council of BEE made more representative.
- Enhances institutional capacity.
Concluding Insight
Energy conservation is the cheapest, fastest, and most inclusive climate solution.
India’s approach combines:
- Legal backing (Energy Conservation Act)
- Institutional leadership (BEE)
- Market mechanisms (carbon trading)
- Behavioural nudges (star labelling, 24°C AC rule)
Together, these measures transform energy efficiency from a technical idea into a national movement.
