The IEA said coal was particularly hard hit, with global demand projected to fall by eight per cent in 2020 – the largest decline since the Second World War.
Coal-fired power generation is set to fall by more than 10 per cent this year. Gas consumption is also expected to drop by five per cent.
The IEA said renewables were the energy source expected to grow in 2020 due to their priority access to grids and low operating costs.
The the economic shutdowns and halt of the aviation industry had caused a “historic shock to the entire energy world”, the agency said.
“The plunge in demand for nearly all major fuels is staggering, especially for coal, oil and gas,” the IEA’s Fatih Birol said.
“Only renewables are holding up during the previously unheard-of slump in electricity use.
“It is still too early to determine the longer-term impacts, but the energy industry that emerges from this crisis will be significantly different from the one that came before.”
