As India braces for surge in heatwave days in 2025, demand rises for air-conditioners
NEW DELHI: Sheetal Kumari and her family used to go without an air conditioner until their home became unbearable during the summer months, when the average maximum temperature soars to nearly 40 degrees Celsius.
The 21-year-old student lives in an urban slum on the outskirts of New Delhi, where homes are often built hastily in narrow spaces without proper ventilation.
For them, the summer heat is more than an inconvenience – it is a health threat.
'My sister had to be hospitalised because of how dangerous the heat was. After that episode, we decided to get an air conditioner,' she told CNA.
The family now rents two air-conditioners for about US$350 for three months in the summer. Sheetal said it saves them money as buying one would have cost them double, with added cleaning and maintenance costs.
But staying cool comes at a cost.
The air conditioners have driven up their power bill – a big drain on their limited finances.
'We've cut back on other expenses and are buying fewer groceries,' Sheetal said.
India is bracing for a potential doubling of the number of heatwave days this year, despite recent thunderstorms bringing some respite.
This has driven the world's most populous country to become the fastest-growing market for air conditioners globally.
The International Energy Agency has projected that India will have more than 1 billion air-conditioning units in operation by 2050.
Summers across the Indian subcontinent are becoming hotter and more humid, with little cooling at night. An estimated 80 per cent of India's population is vulnerable to the impact of heatwaves, which now pose increasing risks to public health and safety.
This growing demand is boosting business for air-conditioner rental shops like Rakshith Kotian's in Mumbai, who supplies cooling units to daily wage labourers and factory workers.
He said he has never been busier.
'The three summer months are my busiest,' he added. 'My earnings during this time carry me through the rest of the year.'
ENVIRONMENTAL CONSEQUENCES
But the growing reliance on air conditioning comes with environmental consequences.
These units push hot air outside, contributing to the 'urban heat island' effect that makes cities even warmer than surrounding rural areas.
On top of that, powering these cooling systems largely depends on fossil fuels. Coal, which already accounts for 55 per cent of India's energy mix, must be burned in greater quantities to keep up with soaring electricity demand.
During the April to June 2024 heatwave, air-conditioning usage surged by 10.4 per cent compared to the same period the year before, according to global energy think tank Ember.
Experts have warned that this creates a vicious cycle: Hotter days increase the need for cooling, which in turn burns more fossil fuels, releasing emissions that worsen the crisis.
Architect and urban designer Adarsha Kapoor believes the key lies in reducing reliance on air-conditioning through smarter building design.
'The building construction and building maintenance techniques have to be such that the internal heat is reduced,' he noted.
'The walls (in India's buildings) are generally thicker. You have walls which can reflect heat rather than retaining heat inside.'
He suggested having 'green roofs' and walls painted with lighter colours that can reflect sunlight.
Yet such solutions remain out of reach for families like Sheetal's.

Shein and Reliance reportedly aim to sell India-made clothes abroad within a year
[MUMBAI/LONDON] Fashion retailer Shein and partner Reliance Retail plan to rapidly expand their Indian supplier base and start overseas sales of India-made Shein-branded clothes within six to 12 months, said two people with knowledge of the matter. The China-founded, Singapore-headquartered e-commerce firm has been discussing plans with the Indian retailer since before the US imposed tariffs on Chinese imports that intensified the need to diversify sourcing, the people said. The aim is to raise Indian suppliers to 1,000 from 150 within a year, they said. In a statement to Reuters, Shein said it licensed its brand for use in India. Reliance did not respond to queries. Shein sells low-priced apparel such as US$5 dresses and US$10 jeans shipped directly from 7,000 suppliers in China to customers in around 150 countries. Its biggest market is the US where it is adjusting to tariffs on low-value e-commerce packages from China which were previously imported duty free. The retailer launched in India in 2018 but its app was banned in 2020 as part of government action against China-linked firms amid border tension with its northeastern neighbour. It returned in February under a licensing deal with the Reliance Industries unit which launched Shein India's website selling Shein-branded clothes produced in local factories. In contrast, Shein's other websites mainly list goods from China. BT in your inbox Start and end each day with the latest news stories and analyses delivered straight to your inbox. Sign Up Sign Up Reliance, controlled by Asia's richest person, Mukesh Ambani, has contracted 150 garment manufacturers and is in discussion with 400 more, said the two people, declining to be identified due to confidentiality concerns. The goal is 1,000 Indian factories making Shein-branded clothes within a year for both the Indian market and to service some of Shein's global websites, the people said. Shein initially wants to list India-made clothes on its US and British websites, one of the people said. Discussions have been ongoing for months and the launch time of six to 12 months could change depending on supplier numbers, the person said. The scale of supplier expansion and export time frame is reported here for the first time. Shein has licensed its brand for domestic use to Reliance which 'is responsible for manufacturing, supply chain, sales and operations in the Indian market,' Shein said. In December, Minister of Commerce and Industry Piyush Goyal told parliament that the Shein-Reliance partnership aimed to create a network of Indian suppliers of Shein-branded clothes for sale 'domestically and globally'. On-demand manufacturing Shein is a fast-fashion behemoth earning annual revenue of over US$30 billion through low prices and aggressive marketing. Most of its products are from China with some made in countries such as Turkey and Brazil. Its expansion in India mirrors interest in the country from the likes of Walmart and others throughout the global fashion and retail industries, particularly those looking for suppliers outside China due to the Sino-US trade war. The Shein India app has been downloaded 2.7 million times across Apple and Google Play stores, averaging 120 per cent on-month growth, showed data from market intelligence firm Sensor Tower. Offerings during its first four months have reached 12,000 designs, a fraction of the 600,000 products on its US site. In the women's dresses category, its cheapest item is priced 349 Indian rupees (S$5.24) versus US$3.39 on the US site as of Jun 9. Shein's Indian partner Reliance, which operates the app, is working with suppliers to assess whether they can replicate Shein's global best-sellers at lower cost, the two people said. Reliance aims to emulate Shein's on-demand manufacturing model, asking suppliers to make as few as 100 pieces per design before increasing production of those that sell well, they said. Executives from Reliance recently visited China to understand Shein's 'innovative' supply chain operations, 'data driven' design processes and 'disruptive' digital marketing, Manish Aziz, assistant vice-president Shein India at Reliance Retail, said in a LinkedIn post in which he called Shein's scale and speed 'truly incredible'. The partnership is one of dozens Reliance has with fashion brands, such as Brooks Brothers and Marks and Spencer. The firm also runs e-commerce site Ajio and its retail network competes with Amazon and Walmart's Flipkart as well as value retailers such as Tata's Zudio. Reliance plans to work with new suppliers to source fabric – especially fabric made using synthetic fibres where India lacks expertise – and import required machinery, the people said. The firm will invest in suppliers and help them grow which in turn will help the Shein-Reliance partnership go global, they said. REUTERS
