Future Trends in Extreme Weather and Energy Demand
Heatwaves and Energy Demand: A Global Perspective
The year 2024 marked a pivotal moment in the global experience with extreme heatwaves, particularly in India, China, and the United States. These heatwaves, some of the hottest on record, triggered a significant surge in the use of air-conditioning (AC) devices. This surge doubled power demand growth in certain months, highlighting the pressing need for more resilient and efficient energy solutions as climate change intensifies.
The Impact on Energy Grids
In China, the months of August and September 2024 saw temperatures soar to new decade-long highs. The increased demand for air-cooling during this period doubled the year-on-year power consumption. For the entire period from April to September, higher air-conditioning needs accounted for 31% of the rise in electricity demand compared to the same period in 2023.
The United States experienced a particularly intense heatwave in June 2024, with average temperatures reaching 23.8°C, the highest for the month in a decade. This drove the entire year-on-year rise in electricity demand, resulting in a 9.4% increase instead of the predicted 1.3% fall. Overall, from April to September 2024, US electricity demand jumped 37% due to air-conditioning needs.
In India, May 2024 was the hottest on record, with temperatures averaging 31.7°C, a 1°C increase from May 2023. Air-conditioning drove nearly one-third of the year-on-year demand increase that month and contributed to 19% of the demand growth from April to September 2024.
The Role of Fossil Fuels
As temperatures soared and electricity demand spiked, all three countries turned to coal-fired power generation to ease the pressure on the grid. In China, the hottest months accounted for 59% of the country’s annual coal-fired power generation surge. In the US, while clean energy met over two-thirds of the June demand growth, the rest was supplied by fossil fuels, including gas and coal. India relied heavily on coal, which met 70% of the increase in May power demand.
Future Projections
As climate change progresses, scientists predict that heatwaves will become more frequent and intense. This, combined with the rising use of air conditioning, especially in the Global South, will lead to a continued spike in electricity demand.
Table: Energy Demand and Fossil Fuel Usage During Heatwaves
| Country | Months Affected | Electricity Demand Increase | Fossil Fuel Usage Increase |
|---|---|---|---|
| China | August, September | 31% (Apr-Sep) | 59% of annual coal use |
| United States | June | 37% (Apr-Sep) | 6.4% (coal), 4.6% (gas) |
| India | May | 19% (Apr-Sep) | 70% (coal) |
Mitigation Strategies
To address these challenges, experts suggest several proactive measures:
1. Promoting Energy-Efficient Air-Conditioning
Encouraging the sale of more energy-efficient air-conditioners can significantly reduce the strain on the power grid during heatwaves. Efforts should focus on distributing efficient cooling solutions, particularly in areas with rapid urbanization.
2. Relying on Renewable Energy
Investing in clean, flexible power sources like solar and wind can help keep grids resilient during extreme weather conditions. This will not only reduce carbon emissions but also ensure a steady supply of electricity.
3. Improving Pricing and Retail Strategies
Improving retail pricing strategies can enable households and businesses to generate cleaner, cheaper power, thereby alleviating the pressure on the grids during peak demand periods.
Expert Insights
Kostantsa Rangelova, an electricity analyst at Ember, underscores the urgency of the situation:
"2024 was the hottest year on record, with heatwaves causing massive spikes in demand. The pressure will only grow as the planet warms. The solution is twofold: scale up efficient air-conditioning adoption to cut costs and ease peak demand, and invest in clean, flexible power to keep grids resilient as extreme weather intensifies. The crisis is accelerating, and our response must, too."

In May 2024, a worker in Ahmedabad, India, carried an air cooler for delivery to a customer during a severe heatwave. This image encapsulated the widespread reliance on air-conditioning devices, highlighting the urgent need for sustainable cooling solutions.
FAQ
What are the key drivers of increased electricity demand during heatwaves?
The primary driver is the surge in air-conditioning use, which significantly increases the power demand during hot months.
How does coal-fired power generation fit into the equation?
As electricity demand spikes, coal-fired power generation is often used to meet the increased demand due to its reliability, but this exacerbates carbon emissions.
What measures can be taken to mitigate the impact of heatwaves on energy grids?
Promoting energy-efficient air-conditioning, investing in renewable energy sources, and improving retail pricing strategies can help alleviate the pressure on grids during peak demand periods.
