India had just seen the warmest year since 1901, when official records were first kept. India’s annual mean temperature climbs from 25.05°C to 25.74°C, according to new environmental figures released by the government on World Environment Day. 2024 was the hottest year globally in the 175-year observational record, and the data shows a rising trend that reflects the global trajectory. Whether renewable energy initiatives are growing quickly enough to have a significant impact emerges as India manages the dual challenges of energy demand and climate sensitivity.
The Numbers Behind the Heat
According to EnviStats India 2025: Environment Statistics, the lowest (night) and maximum (day) annual temperatures have risen notably recently. Nighttime temperatures climbed from 19.32°C to 20.24°C, and daytime temperatures increased from 30.78°C to 31.25°C between 2021 and 2024. These increasing baselines clearly show that India’s climatic profile is changing over time.
Causes of the Rising Heat
The rise in average temperatures is consistent with worldwide trends. It is likely caused by a confluence of factors such as climate change, increased industrialization, and continued reliance on fossil fuels. El Niño tendencies may also have influenced the very high temperatures in 2024. Urbanization, especially in rapidly expanding cities, exacerbates the urban heat island effect, raising local temperatures.

Renewable Energy: Progress So Far
India has made significant strides in increasing its use of renewable energy. Over the last ten years, the amount of power generated by renewable sources has more than tripled, from 65,520 GWh in 2013–14 to 2,25,835 GWh in 2023–24, according to data. At the same time, thermal power has also increased, going from 7,92,053 GWh to 13,26,549 GWh. This implies that while renewable energy is growing, the nation’s dependence on fossil fuels has not yet been significantly reduced. India’s annual mean temperature climbs from 25.05°C to 25.74°C, yet fossil fuel dependence continues.
Climate Impact Already Visible
The effects of warming temperatures extend beyond theory; they are visible in biodiversity, water cycles, public health, and agriculture. Seasonal trends are shifting, with rain becoming concentrated between June and September, based on monthly precipitation records from 2001 to 2024. The rise in the frequency of end-of-monsoon onset and extended rainy seasons to October indicates an environment that is becoming increasingly uncertain.
As a result of freshwater bodies warming, inland fish output has increased from 61 lakh tonnes in 2013–14 to 139 lakh tonnes in 2023–24. Over the same period, marine fish output has also expanded, albeit more slowly, from 34 lakh tonnes to around 45 lakh tonnes.
Regarding biodiversity, the report noted that 1,04,561 of the 16,73,627 faunal species in the world are found in India, reflecting a substantial contribution to the diversity of freshwater, mangrove, estuarine, soil, and marine ecosystems. This variety is at risk due to changing rainfall patterns and rising temperatures. India’s annual mean temperature climbs from 25.05°C to 25.74°C, threatening fragile ecosystems.

Can Renewables Turn the Tide?
Although India’s progress in renewable energy is praiseworthy, it is not yet enough to combat the severity of climate challenges. Accelerating and diversifying the energy transition is necessary, moving beyond solar and wind to decentralized energy, rooftop systems, and grid storage. Increased funding for electric vehicles and renewable hydrogen will also be crucial.
The government’s spending reflects these priorities. With a spending share of Rs 2,433 crore in 2021–22, the Environment Sustainability Sector was the largest, followed by the growing Conservation of Natural Resources Sector. In contrast, the Agro-Forestry Sector spent the least, despite its potential for carbon sequestration.
Localized energy solutions and community-level climate action must be integrated into planning and policy to reverse the warming trend.
The Path Ahead
India is at an inflection point. The apparent slight rise in mean temperature from 25.05°C to 25.74°C is of great concern to urban living, crop cultivation, and water safety. To adjust to this new standard, collective action from the public, private, and civil sectors will be needed. The nation will need to implement an approach with multiple components, ranging from investing in nature-based solutions to updating electric grids. Developing climate-resilient infrastructure, enhancing water retention, and enhancing biodiversity will all be significant contributors.
India’s annual mean temperature climbs from 25.05°C to 25.74°C, reminding policymakers that adaptation and mitigation must go hand in hand.
In Conclusion
India’s 2024 temperature increase is not just a statistical milestone but a wake-up call. India’s annual mean temperature climbs from 25.05°C to 25.74°C amid growing evidence of climate impact. The potential is as great as the stakes. India can shift the climate vulnerability curve toward sustainability with a clear investment in renewable energy and climate resilience. However, the window of opportunity is shrinking.
