    Brewing crisis: How climate change is unravelling India’s tea heartland

    Explained | Agriculture | Mains Paper 3: Major Crops & Cropping Patterns

    Why in the News?

    North Bengal’s tea gardens are in crisis, especially for women workers, due to climate change, pests, low wages, and reduced production, causing economic struggles and increased gender-based hardships.

    What challenges do women tea workers face due to climate change and poor labour conditions?

    • Extreme Heat Exposure: Women work under open skies with no shade, facing soaring temperatures due to climate change. Eg: Workers suffer from headaches, vomiting, and exhaustion while plucking leaves during peak summer months like April and May.
    • Lack of Basic Facilities: Absence of crèches, sanitation, and rest shelters forces women to manage both labour and childcare in unsafe conditions. Eg: Children are hung in cloth cradles tied to trees as mothers continue work in the gardens.
    • Human-Wildlife Conflict: Encroachment of wildlife into tea estates due to changing weather patterns increases risk of attacks. Eg: Leopard attacks have injured several women, despite efforts like using whistles to drive them away.

    Why is tea yield and quality declining in North Bengal?

    • Erratic Rainfall Patterns: The monsoon is no longer evenly spread, with rainfall occurring in short, intense bursts, affecting soil moisture and crop cycle. Eg: Dry spells during critical growth months like February and March reduce yields and degrade leaf quality.
    • Rising Temperatures: Increasing heat reduces the ideal climatic conditions necessary for tea cultivation, impacting both quantity and flavour. Eg: Temperatures crossing 30°C for extended periods lead to loss of the tea’s aroma and taste.
    • Increased Pest and Disease Attacks: Climate change weakens tea bushes, making them more vulnerable to pests and diseases. Eg: Frequent pest attacks force farmers to use chemical sprays, which also degrade leaf quality.

    How do low wages impact the lives of tea plantation workers?

    • Economic Hardship: Low daily earnings make it difficult for workers to meet basic needs such as food, healthcare, and education. Eg: A worker earning only Rs 250 per day struggles to support their family after losing a spouse.
    • Lack of Childcare Support: Insufficient income prevents access to proper childcare facilities, forcing unsafe alternatives at the workplace. Eg: In some cases, children are kept in cloth cradles tied to trees due to the absence of crèche facilities.
    • No Scope for Upward Mobility: With stagnant wages and no savings, workers remain stuck in poverty with no chance to improve living standards. Eg: Despite long-standing demands to increase wages to Rs 600 per day, many still earn significantly less, affecting their long-term well-being.

    What climate-resilient practices are tea estates adopting?

    • Organic Farming: Switching to organic methods reduces chemical use and improves soil health for long-term sustainability. Eg: Some estates have gone fully organic, avoiding chemical fertilisers and promoting natural soil enrichment.
    • Soil Conservation Techniques: Practices like mulching and intercropping help retain moisture, reduce erosion, and maintain fertility during erratic rainfall. Eg: Estates use mulching and intercropping with legumes to prevent soil erosion and conserve moisture during dry spells.
    • Water Management Strategies: Creation of water bodies and rainwater harvesting enhances water availability during prolonged dry periods. Eg: Gardens are building water bodies to improve microclimates and ensure irrigation in the absence of seasonal showers.

    Why is the tea sector overlooked in policy and climate action?

    • Lack of Market Visibility: Despite being globally consumed, tea lacks strong marketing and policy attention compared to other cash crops. Eg: Unlike coffee, tea receives little brand promotion, limiting public and policymaker focus.
    • Neglect of Women Labour Force: Tea is the largest employer of women labourers, yet there is inadequate investment in their welfare or working conditions. Eg: No crèche facilities exist in many gardens, forcing women to hang children from trees during work.
    • Insufficient Climate Funding: Small growers lack access to funds and technical guidance to adopt climate-resilient practices. Eg: High cost of herbal pesticides prevents adoption, while most farmers rely on peer advice instead of expert support.

    Way forward: 

    • Improve Working Conditions and Wages: Ensure minimum wage revision, provide shade, drinking water, crèche facilities, and medical support for women tea workers to enhance their safety and well-being.
    • Promote Climate-Resilient Practices with Institutional Support: Encourage organic farming, soil conservation, and afforestation, backed by government funding and policies tailored to protect both workers and the environment.

    Mains PYQ:

    [UPSC 2024] What are the major challenges faced by Indian irrigation system in recent times? State the measures taken by the government for efficient irrigation management.

    Linkage: The tea gardens are experiencing “prolonged dry spells” and a drop in the “groundwater table”, highlighting a critical challenge for irrigation and water management in the tea heartland.

    Why in the News?

    Authorities have recovered the black box from the crash site of the recent incident in Ahmedabad.

    black box

    About Black Boxes:

    • Purpose: Black boxes are essential flight data recording devices used in aircraft to aid in accident investigation and flight safety analysis.
    • Development: Australian scientist David Warren in 1954, developed the first practical FDR after investigating mid-air explosions.
    • Color and Visibility: Despite the name, black boxes are painted bright orange with reflective material to make them easily visible after a crash.
    • Two Main Types: Aircraft typically have two black boxes:
      1. Cockpit Voice Recorder (CVR) and
      2. Digital Flight Data Recorder (DFDR).
    • Single Unit: Some aircraft integrate both functions into a single combined unit.
    • How does it work?
      • Cockpit Voice Recorder (CVR): The CVR records cockpit audio, including pilot conversations, radio transmissions, alarm sounds, and background noises like engine hum or warning tones.
      • Digital Flight Data Recorder (DFDR): The DFDR logs key flight performance data, including altitude, airspeed, direction, engine parameters, and system operations, capturing thousands of data points per second.
      • Installation Location: Black boxes are usually installed in the tail section of the aircraft, as this area is statistically more likely to remain intact in a crash.
      • Recording Capacity: The CVR records the last 2 hours of cockpit audio on a continuous loop, while the DFDR stores up to 25 hours of flight data.
      • Durability and Protection: Black boxes use solid-state memory chips housed in crash-survivable casings that can endure high-impact forces, extreme temperatures (up to 1,100°C), and deep-sea pressure.
      • Underwater Locator Beacons (ULBs): Each black box includes a beacon that emits signals for up to 30 days, aiding search teams in locating the devices in the event of a water crash.

    Use of Black Boxes in India:

    • Regulation in India: In India, aircraft crash investigations are conducted by the Aircraft Accident Investigation Bureau (AAIB) under the Ministry of Civil Aviation, using black box data as primary evidence.
    • Recent Development (April 2025): India established its first dedicated Flight Recorders Laboratory in New Delhi, strengthening the country’s capability to analyze crash data independently and efficiently.

  • Differentiated Banks – Payment Banks, Small Finance Banks, etc.

    What is Merchant Discount Rate (MDR)?

    Prelims Only | Economics | Mains Paper 3: Indian Economy

    Why in the News?

    The Finance Ministry has firmly denied recent online rumours suggesting that the government is planning to impose Merchant Discount Rate (MDR) charges on UPI transactions.

    About Merchant Discount Rate (MDR):

    • Overview: MDR refers to the fee charged to merchants by banks or payment service providers for processing digital payments made via credit cards, debit cards or other digital modes.
    • Purpose: It serves to compensate multiple stakeholders involved in a digital transaction, including the issuing bank, acquiring bank, payment gateway, and network operator.
    • Fee Structure: MDR is typically calculated as a percentage of the total transaction amount, usually ranging from 1% to 3%, depending on the transaction and merchant type.
    • RBI Regulation: The Reserve Bank of India (RBI) regulates MDR, and merchants are NOT permitted to pass this fee onto customers.
    • Discontinuation: To promote cashless payments, the government waived MDR on UPI and RuPay card transactions in 2020, benefiting small merchants and consumers.

    How does it work?

    • Transaction Flow: When a customer pays digitally, the payment amount is credited to the merchant’s account after deducting the MDR fee.
    • Example: If a customer pays ₹1,000 and the MDR is 2%, the merchant receives ₹980, while the remaining ₹20 is distributed among the banks and service providers.
    • Automatic Deduction: The MDR amount is automatically deducted by the settlement system at the time of transaction processing.
    • Variable Rates: The MDR rate may vary depending on factors such as the type of card used, nature of business, monthly transaction volume, and average transaction value.
    • Merchant Agreements: Merchants are required to sign MDR agreements with their payment service providers before they begin accepting digital payments.
    • Operational Cost: MDR is treated as a part of the merchant’s operational costs when offering customers the convenience of digital payment options.
    [UPSC 2017] Which one of the following best describes the term “Merchant Discount Rate” sometimes seen in news?

    Options: (a) The incentive given by a bank to a merchant for accepting payments through debit cards pertaining to that bank.

    (b) The amount paid back by banks to their customers when they use debit cards for financial transactions for purchasing goods or services.

    (c) The charge to a merchant by a bank for accepting payments from his customers through the bank’s debit cards. *

    (d) The incentive given by the Government to merchants for promoting digital payments by their customers through Point of Sale (PoS) machines and debit cards.

  • Foreign Policy Watch: India-United States

    [13th June 2025] The Hindu Op-ed: Trump’s tariffs and a U.S.-India trade agreement

    op-ed snap | International Relations | Mains Paper 2: Bilateral, Regional and Global Groupings and agreements involving India

    PYQ Relevance:

    [UPSC 2019] What introduces friction into the ties between India and the United States is that Washington is still unable to find for India a position in its global strategy, which would satisfy India’s National self-esteem and ambitions” Explain with suitable examples.

    Linkage: The article points out several trade and economic tensions between the U.S. and India. These include disagreements over the actual size of the U.S. trade deficit with India, the increase of tariffs on steel and aluminium imports from 25% and 10% to 50%, which also affects India, and warnings of possible tariffs on Apple products if they are made in India.

     

    Mentor’s Comment:  In a major decision, five small U.S. businesses won a legal case against former President Donald Trump’s wide-ranging tariffs in the U.S. Court of International Trade. On May 28, 2025, the court ruled that the tariffs—ranging from 10% to 135% and affecting over 100 countries—were unconstitutional and illegal. This ruling matters globally, especially for countries like India, now facing increased 50% tariffs on steel and aluminium.

     Today’s editorial focuses on the  US Courts’ decision on tariffs, a key issue relevant to GS Paper II (International Relations) in the UPSC syllabus.

    _

    Let’s learn!

    Why in the News?

    Recently, on May 28, 2025, a U.S. court ruled that the tariffs, ranging from 10% to 135% and applied to over 100 countries, were against the Constitution and not legal.

    What was the legal challenge to Trump’s tariffs?

    • Unlawful Executive Overreach: Five small U.S. businesses challenged Trump’s tariffs at the U.S. Court of International Trade (CIT), arguing that the President exceeded legal authority by imposing tariffs without Congressional approval. Eg: Firms dealing in wines, bicycles, and fishing equipment claimed economic harm.
    • Violation of Separation of Powers: The lawsuit argued that the President’s sweeping tariffs bypassed legislative and judicial checks, undermining the constitutional framework. Eg: The court noted that trade rules must involve Congress, not unilateral executive orders.
    • Misuse of National Emergency Powers: The court ruled that invoking a “national emergency” does not justify rewriting international tariff agreements. Eg: The CIT stated that such powers cannot be used to override trade commitments under WTO rules.

    Why did the court reject the “national emergency” claim?

    • Lack of Legal Basis: The court ruled that there was no statutory authority for the President to impose retaliatory global tariffs under a vague “national emergency.” Eg: Tariffs up to 135% were applied without Congressional sanction.
    • Overreach of Executive Powers: The court stated that invoking national emergency powers cannot allow the President to override trade laws and international commitments. Eg: It held that such use disrupts the constitutional separation of powers.
    • Absence of Real Emergency: The court found no credible evidence of an immediate or actual threat that would justify emergency trade measures. Eg: The cited trade deficit was not a sudden crisis but a long-standing economic condition.
    • Distortion of Trade Deficit Data: The administration failed to account for services and arms trade while citing trade deficits as justification. Eg: U.S. cited a $44.4 billion deficit with India, while it actually runs a $35–40 billion surplus when services are included.
    • Violation of International Obligations: The court emphasized that the tariffs contradicted U.S. commitments under WTO agreements and eroded global trade norms. Eg: The U.S. applied tariffs even to uninhabited territories like the Heard and McDonald Islands, showcasing arbitrariness.

    How did the U.S. justify tariffs on India after WTO talks?

    • National Security Pretext: The U.S. continued to claim national security grounds for the imposition of tariffs, even after WTO rulings against it. Eg: Despite WTO panels rejecting the justification in 2022, the U.S. raised steel and aluminium tariffs to 50% on India.
    • Strategic Trade Leverage: The U.S. argued that enhanced tariffs served as negotiation tools to pressure trade partners into deals. Eg: The U.S. claimed the tariffs on India helped gain leverage in talks to finalize a bilateral trade agreement.
    • Mutually Agreed Solution Bypass: Though India and the U.S. reached a “mutually agreed solution” at the WTO in 2023, the U.S. still extended new tariffs on India. Eg: The 50% tariffs imposed in 2025 contradicted the earlier settlement, undermining trust in WTO dispute resolution.

    Which issues must India address in a U.S. trade deal?

    • Removal of Additional Tariffs: India must ensure that the U.S. removes punitive tariffs on Indian exports like steel and aluminium, currently raised to 50%. Eg: The continuation of high tariffs impacts India’s manufacturing sector and export competitiveness.
    • Digital Services Tax Clarity: India should seek guarantees that its digital services taxes will not face retaliation from the U.S. Eg: U.S. firms operating in India’s tech sector may be affected unless taxation issues are resolved amicably.
    • Protection from Remittance Tax: India needs to negotiate exemption from the proposed 3.5% tax on remittances under the Trump One Big Beautiful Bill (OBBB). Eg: This would impact millions of Indian diaspora workers sending money back home.
    • H-1B Visa Concerns: India must address growing restrictions and backlash against H-1B visas, which are vital for its IT and service industry. Eg: Tech companies rely heavily on H-1B visas for skilled Indian professionals working in the U.S.
    • Cross-Border Services and Data Flows: India must ensure smooth cross-border delivery of services, including clear data flow regulations and digital trade provisions. Eg: This is critical for India’s BPO and fintech industries, which depend on uninterrupted digital transactions.

    Way Forward:

    • Pursue Balanced Trade Negotiations:
      India should negotiate a comprehensive trade deal that protects its strategic sectors, ensures reciprocity, and strengthens economic resilience without compromising on national interests.
    • Strengthen WTO and Multilateral Engagements:
      India must continue to uphold and reform the WTO-based trade framework, using it as a platform to address disputes, promote fair trade practices, and build coalitions with like-minded nations.

  • Urban Transformation – Smart Cities, AMRUT, etc.

    Urbanisation and the challenge of ideal transit solutions 

    Explained | Enviro & Biodiversity | Mains Paper 3: Infrastructure: Energy, Ports, Roads, Airports, Railways Etc.

    Why in the News?

    India’s path to becoming a “Viksit Bharat” by 2047 relies on transforming its urban areas, as over 60% of the population is expected to live in cities by the 2060s.

    What are the main challenges India faces in achieving efficient urban mobility?

    • Insufficient Public Transport Coverage: Only 37% of urban residents have easy access to public transport, compared to over 50% in countries like Brazil and China. Eg: Many Tier-2 cities still lack proper metro or bus services.
    • Shortage of Urban Buses: India needs about 2,00,000 urban buses, but currently has only 35,000 (including e-buses). Eg: Overcrowded buses in Delhi and Bengaluru during peak hours show the supply-demand gap.
    • Poor Last-Mile Connectivity: Even when metros are available, the cost and difficulty of reaching homes or offices from stations reduce usage. Eg: Metro commuters in Mumbai often rely on expensive auto-rickshaws for last-mile travel.
    • High Cost and Low Returns from Metro Projects: Metros are expensive and slow to build, with lower-than-expected ridership, making cost recovery hard. Eg: Many phases of the Jaipur Metro remain underutilized due to low footfall.
    • Limited Government Subsidies and Private Investment: Unlike developed nations, India cannot afford large recurring subsidies, and private investment is low due to uncertain returns. Eg: E-bus projects in Pune face delays due to funding and maintenance challenges.

    Why is the current investment in metro and e-bus infrastructure falling short?

    • High Cost and Low Ridership: Metro projects involve huge capital and operational costs, but often fail to attract enough passengers to recover expenses. Eg: The Lucknow Metro struggles with low ridership despite high investment.
    • Fare Sensitivity and Last-Mile Issues: People are price-sensitive, and poor last-mile connectivity discourages use of metros and e-buses. Eg: In Hyderabad, a small hike in metro fares led to a drop in daily commuters.
    • Unsustainable Operational Models: E-buses have high replacement and maintenance costs, making them financially unviable in the long run. Eg: Many cities like Nagpur face challenges maintaining their e-bus fleets without subsidies.

    How do trams compare to e-buses in terms of long-term cost-effectiveness?

    • Higher Long-Term Profitability: Trams show about 45% profitability over their typical 70-year life cycle, making them more financially sustainable. Eg: European cities like Vienna continue to expand tram networks due to long-term cost benefits.
    • Lower Operational and Replacement Costs: Trams require less frequent replacements and have lower running costs compared to e-buses, which face high battery and maintenance expenses. Eg: Kolkata’s tram system, though outdated, still operates at a lower cost than many new e-bus services.
    • Better Scalability and Climate Alignment: Trams are more scalable in dense cities and better aligned with climate goals due to zero tailpipe emissions and use of electricity from clean sources. Eg: The planned Kochi tram project is being promoted as a sustainable alternative to road-based transport.

    Which schemes support urban transport in the Budget 2024?

    • PM e-Bus Sewa – Payment Security Mechanism: Aims to deploy and ensure reliable operations of 10,000 urban buses, including electric ones. Eg: Cities like Ahmedabad are using this to expand their bus fleet and improve service reliability.
    • PM e-Drive Scheme (PM Electric Drive Revolution in Innovative Vehicle Enhancement): Supports procurement of 14,000 e-buses, 1,10,000 e-rickshaws, as well as e-trucks and e-ambulances. Eg: New Delhi is using funds to order e-ambulances and expand its e-rickshaw fleet under this initiative.

    Way forward: 

    • Integrated Multi-Modal Transport Planning: Develop seamless connectivity between metro, buses, e-rickshaws, trams, and non-motorised transport (NMT) to reduce last-mile gaps and improve user convenience.
    • Prioritise Cost-Effective and Sustainable Modes: Encourage trams and trolleybuses in high-density corridors through life-cycle cost analysis, while ensuring targeted subsidies for low-income commuters and investment in green fuels like bio-CNG and hydrogen.

    Mains PYQ:

    [UPSC 2019] How is efficient and affordable urban mass transport key to the rapid economic development of India?

    Linkage: The article talks about different types of public transport like buses, metros, trams, and trolleybuses, and how important it is to choose options that are affordable and effective. It stresses the need for a strong and efficient public transport system to deal with the growing challenges of travel in cities. As more people move to cities, the article says urban areas will play a key role in driving India’s economic growth, making good public transport even more important.

  • Foreign Policy Watch: India-Bangladesh

    Is Bangladesh slipping into authoritarianism?

    Explained | International Relations | Mains Paper 2: India & Its Neighborhood – Relations

    Why in the News?

    Bangladesh is seeing major political change as interim leader Dr. Muhammad Yunus delays elections to April 2026 and proposes the “July Proclamation” to reform or replace the 1972 Constitution.

    Why is the ‘July Proclamation’ seen as a threat to Bangladesh’s democratic foundations?

    • Lacks Democratic Legitimacy: It is being pushed by an unelected interim regime without a popular mandate or proper parliamentary debate. Eg: Prof. Yunus’ government is not elected, yet is trying to undertake constitutional reforms meant for a legislature.
    • Distorts Historical Legacy: The move seeks to marginalize the legacy of Sheikh Mujibur Rahman and diminish the significance of December (Victory Day) and August (Mujib’s assassination), promoting July as a new political start. Eg: The July Proclamation downplays Bangladesh’s founding narrative to suit a new political agenda.

    What are the risks of an unelected interim government pursuing constitutional reforms?

    • Lack of Legitimacy and Public Mandate: An interim government is not elected by the people and lacks the constitutional authority to undertake major reforms meant for a parliament or constituent assembly. Eg: In Bangladesh, Prof. Yunus’ government is implementing reforms without elections, violating democratic norms.
    • Potential for Power Consolidation: Such reforms can be used to prolong the tenure of the interim regime, sideline opposition, and weaken checks and balances, paving the way for authoritarian rule. Eg: The banning of the Awami League and the extension of election dates to 2026 raise concerns of power entrenchment.
    • Political Instability and Polarisation: Constitutional changes without bipartisan consensus can lead to unrest, legitimacy crises, and deep political divisions. Eg: The BNP, though opposed to the Awami League, is uncomfortable with the July Proclamation, showing a lack of political unity.

    How could the proposed humanitarian corridor affect regional security?

    • Violation of Sovereignty and Military Tensions: A demilitarised humanitarian corridor, especially if monitored by international forces, may be seen as a breach of national sovereignty by host countries.
      Eg: The Bangladesh Army chief objected to international enforcement in the Rakhine region, fearing it would undermine Bangladesh’s sovereignty.
    • Risk of Weapon Smuggling and Armed Group Access: Without effective monitoring mechanisms, such corridors could be exploited by international armed groups to smuggle weapons and infiltrate conflict zones. Eg: Concerns exist that the proposed corridor into Myanmar’s Rakhine province may be misused by armed groups, threatening both Myanmar and Indian border security.
    • Uncertain Aid Distribution and Escalation of Conflicts: There’s no guarantee that humanitarian aid will reach only the intended civilian population (like Rohingya) and not be diverted to militant factions, escalating regional conflicts. Eg: India fears that lack of clarity over corridor enforcement could worsen militancy in the Northeast and Indo-Myanmar border areas.
    Note: The humanitarian corridor to Myanmar’s Rakhine province is a proposed initiative — not yet implemented — and it was publicly supported by Professor Muhammad Yunus, the Chief Adviser to the interim government of Bangladesh, in a speech on June 7, 2025.

    Why does the sidelining of major parties like BNP and Awami League raise democratic concerns?

    • Undermining of Political Representation: Exclusion of major political parties weakens democratic legitimacy and narrows the space for public representation and opposition. Eg: The ban on the Awami League and the marginalisation of the BNP prevents millions of citizens from having their voices heard in the political process.
    • Emergence of Proxy or Unrepresentative Forces: The vacuum created by sidelining mainstream parties can be filled by unaccountable or extremist groups, increasing political instability. Eg: The rise of the National Citizens Party (NCP), referred to as the ‘King’s Party’ by the BNP, raises fears of state-sponsored political manipulation.

    Way forward: 

    • Inclusive Political Dialogue and Election Roadmap: The interim government must initiate an inclusive dialogue involving all major political parties, including the BNP and Awami League, to build consensus on constitutional reforms and ensure free and fair elections.  
    • Limit Powers of the Interim Government: Clearly define and restrict the mandate of the interim government to conduct elections only, avoiding any major constitutional or policy decisions that should be left to an elected Parliament.

    Science behind right AC Temperature

    Prelims Only | Science Tech | Mains Paper 3: Awareness in various sc and tech fields

    Why in the News?

    The Union Ministry of Power is considering a policy to restrict the temperature range of new air conditioners (ACs) in India to between 20°C and 28°C.

    Important Facts and Keywords related to ACs:

    • Efficiency Ratings: ACs have ratings like SEER (Seasonal Energy Efficiency Ratio) or EER (Energy Efficiency Ratio). A higher rating means the AC uses less power to cool the same space.
    • Inverter Technology: Some ACs use inverter compressors, which adjust speed instead of turning on and off repeatedly. This saves energy and keeps the room temperature more stable.
    • Humidity Control: ACs also help by removing moisture from the air. This keeps humidity around 40–60%, which feels more comfortable and prevents mold.
    • Cooling Capacity: ACs are measured in tons. A “ton” of cooling comes from the amount of heat needed to melt 1 ton (~2,000 pounds) of ice in 24 hours.

    How do Air Conditioners Work?

    • Basic Idea: Air conditioners (ACs) work like a heat-moving machine. They take heat from inside your room and push it outside, making the room cooler. They do this using a special fluid called a refrigerant, and a system called the vapour-compression cycle.
    • Main Parts and What They Do:
      • Evaporator: This part is inside your room. The refrigerant, which is very cold here, absorbs heat from the indoor air and turns into a gas. It also removes moisture, so your room feels less humid.
      • Compressor: This is outside the house. It squeezes the refrigerant gas, making it very hot (about 90°C) and high-pressure. This part uses the most electricity in the AC.
      • Condenser: The hot gas then flows through the condenser coil outside. It releases heat into the outdoor air and turns back into a liquid.
      • Expansion Valve: This part lowers the pressure of the liquid refrigerant, making it cold again before it goes back to the evaporator to repeat the cycle.
    • Refrigerant: The refrigerant is a specially designed gas that changes state easily at low temperatures and pressures, making it ideal for absorbing and releasing heat rapidly. Modern refrigerants like R-32 or R-410A are more energy-efficient and environmentally safer than older ones like CFCs and HCFCs.

    Why limit AC Temperature settings?

    • Energy Efficiency Data: According to the Bureau of Energy Efficiency (BEE), setting an AC to 24°C instead of a lower setting can save 6% electricity per 1°C increase.
    • National Impact: If adopted widely, this temperature setting could help India save 20 billion units of electricity annually.
    • Health Risks at Low Temperatures: Temperatures below 18°C are linked to hypertension, asthma, and respiratory infections, especially among children, the elderly, and people with weakened thermoregulation.
    • Evidence from Global Studies: Research in Japan, the UK, and New Zealand shows that slightly warmer indoor settings lead to better respiratory and cardiovascular health.
    • WHO Recommendation: The World Health Organization advises 18°C as the minimum safe indoor temperature in temperate climates.
    • Thermal Comfort Standards: Guidelines like ASHRAE-55 and ISO 7730 suggest optimal indoor temperatures between 20°C and 24°C for lightly clothed people, with adjustments based on local climate and culture.

    Global Cooling Trends and the Need for Regulation:

    • Global AC Usage Growth: As of 2022, there were an estimated 2 billion air conditioners in use worldwide, with residential units tripling since 2000, especially in India and China.
    • Access Gap in Asia-Pacific: Despite this growth, 43% of the Asia-Pacific population still lacks access to adequate cooling solutions.
    • Environmental Impact: Air conditioning significantly increases electricity use and carbon emissions, especially in countries with fossil fuel-dependent grids.
    • India’s AC Load Projection: By 2030, India’s total connected AC load is expected to reach 200 gigawatts, requiring urgent demand management strategies.
    • Consumer Awareness Tools: Initiatives like default settings at 24°C and energy labelling empower consumers to make informed energy-efficient choices.
    • Benefits of Regulation: A regulated temperature range can help lower energy consumption, reduce peak power demand, and support public health.
    [UPSC 2003] Consider the following statements:

    1. Steam at 100°C and boiling water at 100°C contain the same amount of heat.

    2. Latent heat of fusion of ice is equal to the latent heat of vaporization of water.

    3. In an air-conditioner, heat is extracted from the room-air at the evaporator coils and is rejected out at the condenser coils.
