Air Conditioner Energy Consumption in India 2026: Electricity Usage, Grid Impact & Running Costs
An exhaustive, data-driven investigation into India's cooling electricity surge: peak summer grid demand, city-by-city monthly running expenses, BEE star rating savings, DISCOM tariff escalation, and the 2050 cooling boom.
India is standing at the precipice of the largest cooling revolution in modern human history. As average summer temperatures regularly cross 45°C across the Indo-Gangetic plain and coastal relative humidity remains locked above 80%, room air conditioners have transitioned from luxury appliances into critical life-support infrastructure.
However, this rapid adoption comes with immense electrical consequences. Today, room air conditioners consume an estimated 120 to 150 Terawatt-hours (TWh) of electricity annually—accounting for nearly 10% of India's total power generation. During peak summer heatwaves in cities like Delhi, Mumbai, and Ahmedabad, air conditioning alone drives 40% to 60% of total electrical grid demand, testing distribution transformers and grid resilience to their breaking point.

1. The Macro Picture: India's Cooling Conundrum & Peak Grid Load
India's electrical power system is confronting a phenomenon known among electrical grid engineers as "Thermal Load Coincidence." Unlike industrial power consumption, which remains relatively stable around the clock, residential air conditioning load spikes aggressively during the exact hours when human physiological stress peaks: 2:00 PM to 5:00 PM (afternoon peak) and 10:00 PM to 3:00 AM (nighttime residential sleep peak).
According to operational reports from the Central Electricity Authority (CEA) and Regional Load Despatch Centres (NLDC/RLDCs), all-India peak electricity demand crossed an unprecedented 250 Gigawatts (GW) during recent heatwaves. In major metropolitan areas, the correlation between ambient temperature and electrical demand is almost perfectly linear above 32°C.
The Delhi Heatwave Case Study (June 2024–2026 CEA Load Data)
In June 2024, Delhi recorded an all-time record peak electrical demand of 8,656 Megawatts (MW). Detailed load decomposition by the Delhi State Load Despatch Centre (SLDC) revealed that between 4,300 MW and 4,750 MW (50% to 55%) was driven exclusively by space cooling equipment (air conditioners, desert coolers, and chiller plants).
Crucially, the peak load occurred at 11:24 PM, not mid-afternoon. This nighttime surge happens because millions of concrete residential buildings absorb solar radiation throughout the day (thermal mass inertia) and re-radiate heat late into the night. When residents retire to bed, tens of thousands of inverter compressors fire up simultaneously, creating severe stress on distribution transformers and localized feeder lines.
Similar patterns are documented in Mumbai, where the cooling share hovers at 40% to 45% during the pre-monsoon swelter (March–May) and October post-monsoon heat, pushing local demand over 4,300 MW across Tata Power, Adani Electricity, and MSEDCL distribution zones. In Chennai and Kolkata, high coastal humidity creates an unrelenting 9-month cooling season, elevating baseload electricity demand year-round.
2. City-by-City Household AC Running Costs & Usage Hours
The actual financial impact of running an air conditioner varies dramatically depending on where you live in India. Two variables determine your monthly bill: local climate (daily running hours) and state DISCOM electricity tariffs.
For example, while Delhi residents face hotter temperatures and run their ACs for 12 to 14 hours per day in May and June, their effective domestic tariff sits around ₹7.50 to ₹8.50 per unit (even after factoring in Power Purchase Adjustment Cost surcharges). In contrast, a resident in Mumbai or Thane running their AC for just 9 hours a day can face high-tier slab tariffs exceeding ₹12.50 to ₹14.00 per unit under Adani Electricity or MSEDCL, resulting in the highest AC power bills in the entire nation.
The table below models a typical Indian household running a standard 1.5 Ton Inverter AC during the primary cooling season. Calculations use certified BEE test metrics (1.10 kWh/hr effective input for 3-Star vs 0.80 kWh/hr effective input for 5-Star at 24°C setpoint) across state electricity regulatory commission tariff orders.
| City & Primary DISCOM | Avg. Daily Hours (Summer) | Active Months/Yr | Effective Tariff (₹/kWh) | 3-Star Monthly Cost | 5-Star Monthly Cost | Monthly Saving |
|---|---|---|---|---|---|---|
Delhi-NCR BRPL / BYPL / TPDDL | 13.0 hrs | 6.5 mos | ₹8.20 | ₹3,518 | ₹2,558 | ₹960 |
Mumbai (MMR) Adani / Tata / MSEDCL (Highest) | 9.5 hrs | 9.0 mos | ₹12.40 | ₹3,889 | ₹2,827 | ₹1,062 |
Chennai TANGEDCO | 10.5 hrs | 9.5 mos | ₹8.50 | ₹2,945 | ₹2,142 | ₹803 |
Bengaluru BESCOM (Lowest Usage) | 5.0 hrs | 3.5 mos | ₹7.75 | ₹1,279 | ₹930 | ₹349 |
Kolkata CESC / WBSEDCL | 11.0 hrs | 8.0 mos | ₹8.90 | ₹3,231 | ₹2,350 | ₹881 |
Hyderabad TSSPDCL | 9.0 hrs | 6.0 mos | ₹8.60 | ₹2,554 | ₹1,858 | ₹696 |
Ahmedabad Torrent Power / UGVCL | 11.5 hrs | 7.0 mos | ₹7.90 | ₹2,998 | ₹2,180 | ₹818 |
Pune MSEDCL | 7.5 hrs | 5.0 mos | ₹11.20 | ₹2,772 | ₹2,016 | ₹756 |

Tariffs represent weighted non-subsidized domestic slabs (>300 units/mo) including regulatory surcharges, fuel adjustment charges (FAC/FSA), and electricity duty as of 2026. For a customized calculation, see our AC Electricity Bill Calculator.
3. Electricity Tariff Escalation Across Indian DISCOMs (2020–2026)
When purchasing an air conditioner, consumers often make the mistake of evaluating running costs using yesterday's electricity rates. Across India, domestic electricity tariffs have experienced steady upward revisions driven by three fundamental cost pressures:
- Fuel Surcharge Adjustments (FCA/PPAC): Rising landed costs of thermal coal and imported blending coal automatically pass through to consumer bills via quarterly fuel surcharges (ranging from 12% to 32% over base rates).
- Cross-Subsidy Reductions: State regulators are gradually rationalizing tariff slabs, reducing the historical cross-subsidies from industrial users to high-consumption domestic households.
- Green Energy & Transmission Investments: Upgrades to interstate transmission lines (ISTS) to evacuate renewable solar and wind power are reflected in higher network wheeling charges.
| State / DISCOM Jurisdiction | 2020 Tariff (₹/kWh) | 2022 Tariff (₹/kWh) | 2024 Tariff (₹/kWh) | 2026 Tariff (₹/kWh) | 6-Yr CAGR |
|---|---|---|---|---|---|
| Maharashtra (MSEDCL / Adani Mumbai) | ₹9.80 | ₹10.75 | ₹11.60 | ₹12.40 | +4.0% |
| Delhi (DERC High-Consumption Slabs + PPAC) | ₹6.50 | ₹7.10 | ₹7.80 | ₹8.20 | +3.9% |
| Tamil Nadu (TANGEDCO Slabs >500 Units) | ₹6.60 | ₹7.50 | ₹8.15 | ₹8.50 | +4.3% |
| Karnataka (BESCOM Domestic High Slab) | ₹6.90 | ₹7.25 | ₹7.50 | ₹7.75 | +2.0% |
| West Bengal (CESC Kolkata Domestic) | ₹7.40 | ₹7.95 | ₹8.50 | ₹8.90 | +3.1% |
| All-India Urban Domestic Average | ₹6.80 | ₹7.45 | ₹8.05 | ₹8.45 | +3.7% |

4. BEE Star Rating Evolution & ISEER Improvement Timeline
The single most effective public policy intervention in India's cooling sector has been the Standards & Labelling (S&L) program administered by the Bureau of Energy Efficiency (BEE) under the Ministry of Power.
Initially launched as a voluntary program in 2006 and made mandatory in 2010, BEE's regulatory approach centers on a "ratchet mechanism": every 2 to 3 years, BEE raises the minimum energy efficiency threshold required to earn each star rating. An air conditioner that earned a prestigious 5-star label in 2012 would fail to qualify even as a 1-star model under current standards.
In 2018, BEE introduced the revolutionary Indian Seasonal Energy Efficiency Ratio (ISEER) standard (IS 1391 Part 1 & Part 2). Unlike older static EER standards that evaluated performance at an arbitrary single outdoor temperature (35°C), ISEER weights energy consumption across 54 outdoor temperature bins matching India's actual seasonal weather profile (24°C to 43°C).
| Policy Period | Efficiency Metric | 1-Star Threshold | 3-Star Threshold | 5-Star Threshold | Market Flagship ISEER | Avoided Capacity |
|---|---|---|---|---|---|---|
| 2010 – 2013 | EER (Static 35°C) | 2.30 – 2.49 | 2.70 – 2.89 | ≥ 3.10 | 3.30 | ~3.2 GW |
| 2014 – 2017 | EER (Tightened) | 2.70 – 2.89 | 3.10 – 3.29 | ≥ 3.50 | 3.75 | ~6.8 GW |
| 2018 – 2021 | ISEER Introduced | 3.10 – 3.29 | 3.50 – 3.99 | ≥ 4.50 | 5.20 | ~10.5 GW |
| 2022 – 2024 | ISEER Ratchet 1 | 3.30 – 3.49 | 3.80 – 4.39 | ≥ 5.00 | 5.40 | ~13.2 GW |
| 2025 – 2026 (Current) | ISEER Tightened Band | 3.30 – 3.49 | 3.90 – 4.49 | ≥ 5.00 | 5.80+ | >15.4 GW |
Source: Bureau of Energy Efficiency (BEE) Schedule 19 for Room Air Conditioners and Annual S&L Energy Savings Verification Reports.
Between 2010 and 2026, the electricity required to produce a standard ton of cooling has dropped by over 40%. This technological leapfrog has avoided the construction of more than thirty 500-MW coal-fired thermal generation units across India.
5. Inverter Technology vs Fixed-Speed: Compressor Modulation & Grid Stability
The mass-market transition from fixed-speed (non-inverter) air conditioners to variable-frequency Inverter ACs has completely transformed India's power distribution landscape:
❌ Old Fixed-Speed (Non-Inverter) AC
- All-or-Nothing Duty Cycle: The compressor runs at 100% full speed (1,500W–1,800W) until thermostat setpoint is reached, then shuts down completely.
- Severe Inrush Current: Every time the compressor cycles ON, it draws a locked-rotor surge of 35A to 45A for 300–500 milliseconds.
- Transformer Stress: Synchronized startup surges during hot summer afternoons cause localized voltage dips and frequent distribution transformer burnouts.
- Low Part-Load Efficiency: Operates at maximum power draw even when ambient temperature drops to 27°C at night.
✅ Modern Variable-Speed Inverter AC
- Continuous Modulation: Brushless DC (BLDC) compressor modulates smoothly between 20% and 110% capacity based on thermal load.
- Soft-Start Electronics: Power electronics boards ramp up compressor frequency gradually from 0 Hz without any inrush current spike (maximum starting draw <6A).
- Grid Flattening: Once the target room temperature is established, power consumption throttles down to just 250W to 450W, reducing neighborhood transformer load by ~70%.
- High Part-Load Efficiency: Over 65% of Indian summer hours occur at part-load temperatures (26°C–34°C), where inverter heat exchangers operate at peak COP.
Inverter air conditioners now represent over 85% of all residential split AC sales in India. Without this widespread transition, the CEA estimates that Delhi's peak summer load would have breached 10,500 MW, likely triggering rolling load shedding across residential sectors.
6. Lifecycle Economics: 3-Star vs 5-Star AC Over 10 Years
The debate between 3-Star and 5-Star ACs is one of the most frequently searched topics by Indian homebuyers. To evaluate the true financial trade-off, BestAC developed a rigorous 10-year Total Cost of Ownership (TCO) mathematical model.
Our model assumes standard 1,600 annual operating hours (roughly 8 hours/day for 200 days), an initial benchmark tariff of ₹8.50/kWh, a conservative 4% annual tariff inflation rate, and identical routine servicing schedules.
| Cost Component (10-Year Lifecycle) | 1.5T 3-Star Inverter AC | 1.5T 5-Star Inverter AC | Financial Variance |
|---|---|---|---|
| Average Upfront Retail Purchase Price | ₹34,000 | ₹44,500 | +₹10,500 upfront |
| BEE Certified Annual Consumption (1,600 hrs) | 1,080 kWh / yr | 790 kWh / yr | 290 kWh/yr saved (-27%) |
| Year 1 Electricity Bill (@ ₹8.50/unit) | ₹9,180 | ₹6,715 | ₹2,465 annual saving |
| Cumulative 5-Year Electricity Expense | ₹49,720 | ₹36,370 | ₹13,350 power saved |
| Cumulative 10-Year Electricity Expense (4% CAGR) | ₹1,10,250 | ₹80,660 | ₹29,590 power saved |
| Estimated 10-Year Maintenance & Servicing | ₹12,000 | ₹14,500 | +₹2,500 (Complex PCB/Parts) |
| Total 10-Year Outflow (Machine + Power + Service) | ₹1,56,250 | ₹1,39,660 | ₹16,590 Net Pocket Savings |
| Net Payback & Break-Even Horizon | — | 3.9 Years | 158% ROI over 10 Years |
The Verdict: If you use your air conditioner for more than 1,200 hours per year (equivalent to 6+ hours per day across 6 months) and live in your own home, a 5-star AC is a guaranteed financial investment that generates an effective 15% to 20% annual return on the incremental capital spent.
7. Refrigerant Thermodynamics: R-32 vs R-410A Efficiency Comparison
The chemical refrigerant circulating through your air conditioner's copper tubing is the thermodynamic medium that transfers heat from your bedroom to the outside air. The phase-down of older refrigerants has had a direct, measurable impact on energy consumption.
Under the Kigali Amendment to the Montreal Protocol, India is phasing down high Global Warming Potential (GWP) hydrofluorocarbons (HFCs). While obsolete R-22 (an ozone-depleting HCFC) has been largely banned for new equipment, the industry has transitioned away from R-410A toward R-32 and natural hydrocarbons like R-290 (Propane).
| Thermodynamic & Safety Metric | R-410A (Older Standard) | R-32 (Current Mass Market) | R-290 Propane (Next-Gen) |
|---|---|---|---|
| Chemical Composition | 50% R-32 / 50% R-125 Blend | 100% Pure Difluoromethane | 100% Pure Propane |
| Global Warming Potential (GWP 100-yr) | 2,088 | 675 (-68% lower) | 3 (Ultra-Low) |
| Ozone Depletion Potential (ODP) | 0 | 0 | 0 |
| Volumetric Cooling Capacity (kJ/m³) | ~3,900 | ~4,350 (+11.5% higher) | ~2,600 |
| Theoretical Cycle COP at 35°C | 4.30 | 4.75 (+10.4% efficient) | 4.85 |
| Typical Refrigerant Charge (1.5T Unit) | 1,150 – 1,300 grams | 800 – 950 grams (-28%) | 300 – 360 grams |
| ASHRAE 34 Safety & Flammability Class | A1 (Non-Flammable) | A2L (Mildly Flammable) | A3 (Highly Flammable) |
Source: UNEP RTOC (Refrigeration, Air Conditioning and Heat Pumps Technical Options Committee) & AEEE Refrigerant Assessment Data.
Because R-32 possesses a substantially higher latent heat of vaporization and heat transfer coefficient, compressors operate at lower compression ratios. This directly translates to an 8% to 12% reduction in kilowatt-hour electricity draw under extreme 43°C to 48°C ambient conditions compared to identical cooling delivered with R-410A.
8. Solar AC Adoption Rate & Renewable Cooling Potential
Air conditioning is the only major household load where electrical demand naturally coincides with solar generation. Peak solar production in India occurs precisely between 11:30 AM and 3:30 PM, matching the hours when direct solar irradiance heats building envelopes to maximum levels.
The Rooftop Solar Math: PM Surya Ghar Muft Bijli Yojana
Under the central government's PM Surya Ghar initiative targeting 10 million solar rooftops, a typical 3 kW rooftop solar array costs approximately ₹70,000 to ₹85,000 post-subsidy and generates 12 to 14 units (kWh) of clean electricity every single sunny day.
A modern 1.5 Ton 5-Star Inverter AC running for 8 daytime hours (9:00 AM to 5:00 PM) consumes approximately 6.5 to 8.0 units. Therefore, a 3 kW solar array does not merely offset the AC; it produces a 30% to 50% surplus that covers the refrigerator, ceiling fans, computers, and water pumps.
Pure DC Solar ACs vs Grid-Tied Solar Net Metering
While several manufacturers market dedicated "Solar ACs" that connect directly to photovoltaic panels via DC inputs without an inverter, their current market adoption remains under 1% of total residential AC sales.
The reason is purely economic: dedicated DC solar ACs cost ₹65,000 to ₹90,000 for the unit alone and cannot utilize solar power when the AC is switched off during winter months. In contrast, installing a standard 5-star inverter AC paired with a whole-home grid-tied rooftop solar system with net metering allows surplus daytime units to be banked with the local DISCOM, drastically slashing both summer AC bills and winter power expenses.
9. India Cooling Action Plan (ICAP) & IEA 2050 Projections
Recognizing the impending strain on national energy security, India became the first country in the world to launch a comprehensive national cooling roadmap: the India Cooling Action Plan (ICAP), published by the Ministry of Environment, Forest and Climate Change (MoEFCC) in March 2019.
Reduction in national cooling demand across all sectors by 2037-38.
Reduction in cooling energy requirements through mandatory building bye-laws and ISEER hikes.
Reduction in refrigerant demand through low-GWP transitions and leak-tight servicing.
Certified HVAC technicians trained under Skill India to eliminate improper gas venting.
The IEA 2050 Trajectory: The Looming "Cold Crunch"
Despite the efficiency strides achieved under BEE and ICAP, the sheer magnitude of demographic and economic expansion will place unprecedented pressure on India's grid infrastructure.
According to the International Energy Agency (IEA) landmark report "The Future of Cooling":
- Room AC Penetration: Currently, only approximately 8% to 10% of Indian households own an air conditioner (compared to >90% in the United States and Japan, and >60% in urban China).
- The 2038 Milestone: By 2038, household penetration is projected to exceed 40%, driving the active room AC installed base past 300 million units.
- The 2050 Explosive Peak: By 2050, India's total operational room AC stock will approach 1 Billion units. Space cooling electricity demand will experience an eightfold (8×) increase, soaring from ~130 TWh today to over 1,000 TWh annually.
- Required Generation Capacity: To meet peak cooling loads in 2050 without frequent blackouts, India will require an estimated 300+ GW of dedicated generation and transmission capacity—equivalent to the entire electric power capacity of the European Union today.
10. Seasonal Electricity Consumption Profiles Across India
Unlike North America or Europe where space heating dominates winter energy bills, India's residential electricity consumption is dictated almost entirely by seasonal cooling phases:
Pre-Summer & Peak Heatwaves (March – June)
Maximum thermal load. Ambient temperatures range from 38°C to 48°C. Inverter compressors run at 80% to 110% capacity for hours to overcome massive thermal envelope transfer. AC electricity bills represent 55% to 70% of total household utility expenses.
Monsoon & High Humidity (July – September)
Latent heat dominates. Outdoor temperatures drop to 30°C–34°C, but relative humidity surges to 75%–92%. ACs must run in "Dry" dehumidification mode, condensing liters of moisture per hour. Power consumption moderates to 600W–850W average input.
Post-Monsoon Transition (October – November)
Pleasant afternoons and mild nights. AC usage drops to 3–5 hours during sleeping hours. Inverter compressors throttle down to minimum modulation frequencies (20% to 35% load), drawing just 250W–400W.
Winter Dormancy vs All-Weather Heat Pumps (December – February)
Cooling load drops to zero across Northern and Central India. However, sales of "Hot & Cold" All-Weather Inverter Heat Pump ACs are expanding at 25% annually in Delhi-NCR, Punjab, Haryana, and Kashmir, delivering winter room heating at a COP of 3.2—consuming 65% less electricity than traditional 2,000W resistance rod room heaters.
11. Frequently Asked Questions (FAQ)
1.What percentage of peak summer electricity demand in Indian cities is caused by air conditioners?
Air conditioners account for approximately 40% to 60% of peak summer electricity demand in major Indian metropolitan cities like Delhi, Mumbai, Ahmedabad, and Chennai. In Delhi, during extreme heatwaves when power demand exceeded 8,650 MW in June 2024, space cooling accounted for over 4,300 MW (over 50% of the capital's entire electric grid load), according to State Load Despatch Centre (SLDC) and Central Electricity Authority (CEA) data.
2.How much total electricity do air conditioners consume annually in India?
Room and commercial air conditioners in India consume an estimated 120 to 150 Terawatt-hours (TWh) of electricity annually. This represents approximately 9% to 11% of India's total gross electricity generation (~1,700 TWh). Residential room ACs account for roughly 65 to 75 TWh of this total, with demand growing at 10-12% annually as household AC penetration expands.
3.How much does it cost to run a 1.5 ton AC for one month in India in 2026?
Running a 1.5-ton AC for 8 hours daily during summer costs between ₹1,800 and ₹4,600 per month depending on the city, local DISCOM tariff slab, and the BEE star rating. For a 3-star inverter AC (1.10 kWh/hr effective), monthly costs range from ₹2,100 in Bengaluru to ₹4,150 in Mumbai. For a 5-star inverter AC (0.80 kWh/hr effective), monthly bills range from ₹1,550 in Bengaluru to ₹3,050 in Mumbai.
4.Which Indian city has the highest monthly AC electricity running cost?
Mumbai has the highest household AC running cost among major Indian metros, averaging ₹3,800 to ₹5,200 per month during peak summer for a 1.5-ton unit. Although Delhi experiences higher ambient temperatures, Mumbai's steep progressive electricity tariff slabs (exceeding ₹12 to ₹14 per kWh for consumption over 300 units under Adani Electricity, Tata Power, and MSEDCL) make running an AC in Mumbai significantly more expensive per kilowatt-hour.
5.How much money does a 5-star AC save compared to a 3-star AC over a 10-year lifetime?
Over a 10-year lifespan (operating 1,600 hours annually at a blended national tariff of ₹8.50/kWh with 4% annual tariff inflation), a 1.5-ton 5-star inverter AC saves approximately ₹31,000 to ₹34,000 in electricity bills compared to a 3-star inverter AC. After deducting the upfront price premium of ₹10,000 to ₹12,000, the net lifetime financial profit is between ₹19,000 and ₹23,000, with a break-even timeline of 3.8 to 4.2 years.
6.How has the BEE ISEER rating improved air conditioner efficiency in India over time?
Since the Bureau of Energy Efficiency (BEE) introduced the Indian Seasonal Energy Efficiency Ratio (ISEER) in 2018, the average energy efficiency of room ACs sold in India has improved by over 35%. In 2018, a 5-star AC required an ISEER of 4.50. Under the tightened 2024-2026 standards, 5-star split ACs must achieve ISEER ≥ 5.00, with flagship models reaching ISEER 5.80+. BEE's Standards & Labelling program has avoided over 15 GW of peak power generation capacity nationally.
7.How has the shift to inverter AC technology impacted India's electric grid?
Inverter AC market penetration surged from under 12% in 2015 to over 85% in 2026. Inverter units use variable-speed BLDC compressors that soft-start without the 35A-45A locked-rotor current surges typical of old fixed-speed compressors. Furthermore, inverter ACs modulate down to 20-40% capacity once the room cools, stabilizing transformer loads and reducing sudden synchronized grid dropouts during extreme heatwave events.
8.Why is R-32 refrigerant more energy-efficient than R-410A in Indian climates?
R-32 refrigerant provides approximately 10% to 12% higher volumetric cooling capacity and higher thermodynamic Coefficient of Performance (COP) compared to R-410A. R-32 requires 20% to 30% less refrigerant charge by weight and has superior heat transfer properties inside microchannel condenser tubes. Crucially, R-32 maintains higher cycle efficiency in ambient temperatures exceeding 45°C and has a Global Warming Potential (GWP) of 675 versus 2,088 for R-410A.
9.Can rooftop solar panels offset air conditioner electricity consumption in India?
Yes. In India, daytime residential cooling demand directly coincides with peak solar generation (11:00 AM to 4:00 PM). Under the PM Surya Ghar Muft Bijli Yojana, a standard 3 kW grid-tied rooftop solar system generates 12 to 14 units (kWh) of electricity daily. A 1.5-ton 5-star inverter AC running for 8 hours during the day consumes 6 to 8 units, meaning a 3 kW solar array completely offsets daytime AC running costs with surplus power exported to the grid.
10.What are the key cooling energy reduction targets under the India Cooling Action Plan (ICAP)?
The India Cooling Action Plan (ICAP), launched by the Ministry of Environment, Forest and Climate Change (MoEFCC), outlines targets by 2037-38: (1) Reduce cooling demand across all sectors by 20% to 25%; (2) Reduce space cooling energy requirements by 25% to 40%; (3) Reduce refrigerant demand by 25% to 30%; and (4) Train and certify 100,000 servicing technicians under the Skill India Mission to prevent refrigerant leaks and maintain design energy efficiency.
