The International Energy Agency on Friday said demand for electricity in India is expected to spike by 8 percent in the current year, driven by strong economic activity and powerful heat waves.
Growth in demand in 2024 and 2025 is forecast to be among the highest levels in the past two decades, new IEA report finds, with solar PV alone expected to meet half of the increase.
The world’s demand for electricity is rising at its fastest rate in years, driven by robust economic growth, intense heatwaves and increasing uptake of technologies that run on electricity such as EVs and heat pumps, according to a new report by the IEA. At the same time, renewables continue their rapid ascent, with solar PV on course to set new records.
Global electricity demand is forecast to grow by around 4 percent in 2024, up from 2.5 percent in 2023, the IEA’s Electricity Mid-Year Update finds.
This would represent the highest annual growth rate since 2007, excluding the exceptional rebounds seen in the wake of the global financial crisis and the Covid-19 pandemic.
The strong increase in global electricity consumption is set to continue into 2025, with growth around 4 percent again, according to the report.
Renewable sources of electricity are also set to expand rapidly this year and next, with their share of global electricity supply forecast to rise from 30 percent in 2023 to 35 percent in 2025.
The amount of electricity generated by renewables worldwide in 2025 is forecast to eclipse the amount generated by coal for the first time.
Solar PV alone is expected to meet roughly half of the growth in global electricity demand over 2024 and 2025 – with solar and wind combined meeting as much as three-quarters of the growth.
Despite the sharp increases in renewables, global power generation from coal is unlikely to decline this year due to the strong growth in demand, especially in China and India, according to the report.
As a result, carbon dioxide (CO2) emissions from the global power sector are plateauing, with a slight increase in 2024 followed by a decline in 2025.
However, considerable uncertainties remain: Chinese hydropower production recovered strongly in the first half of 2024 from its 2023 low.
If this upward trend continues in the second half of the year, it could curb coal-fired power generation and result in a slight decline in global power sector emissions in 2024.
China is also set to see significant demand growth of more than 6 percent, as a result of robust activity in the services industries and various industrial sectors, including the manufacturing of clean energy technologies.
After declining in 2023 amid mild weather, electricity demand in the United States is forecast to rebound this year by 3 percent amid steady economic growth, rising demand for cooling and an expanding data centre sector.
By contrast, the European Union will see a more modest recovery in electricity demand, with growth forecast at 1.7 percent, following two consecutive years of contraction amid the impacts of the energy crisis.
In many parts of the world, increasing use of air-conditioning will remain a significant driver of electricity demand. Multiple regions faced intense heat waves in the first half of 2024, which elevated demand and put electricity systems under strain, the report finds.
“Growth in global electricity demand this year and next is set to be among the fastest in the past two decades, highlighting the growing role of electricity in our economies as well as the impacts of severe heat waves,” said Keisuke Sadamori, IEA Director of Energy Markets and Security. “It’s encouraging to see clean energy’s share of the electricity mix continuing to rise, but this needs to happen at a much faster rate to meet international energy and climate goals. At the same time, it’s crucial to expand and reinforce grids to provide citizens with secure and reliable electricity supply – and to implement higher energy efficiency standards to reduce the impacts of increased cooling demand on power systems.”
With the rise of artificial intelligence (AI), the electricity demand of data centres is drawing increased attention, underscoring the need for more reliable data and better stock taking measures.
The report highlights the wide range of uncertainties concerning the electricity demand of data centres, including the pace of deployment, the diverse and expanding uses of AI, and the potential for energy efficiency improvements.
Better collection of electricity consumption data of the data centre sector will be essential to identify past developments correctly and to better understand future trends.
