The International Energy Agency, the global energy watchdog, predicted renewables would provide half of the world's electricity by 2030. But it warned that emissions were still too high to prevent temperatures rising above a key threshold of 1.5C.

The Paris-based energy agency's report, released on Tuesday, was not all doom and gloom. It praised the significant progress countries had made in expanding renewable energy and supporting consumers with the shift to electric vehicles and heat pumps instead of gas boilers.

The report said the growth in clean energy and technologies was "impressive". In 2020, one in 25 cars sold was electric. Just three years later this number has risen to one in five. "The transition to clean energy is happening worldwide and it's unstoppable.

"It's not a question of 'if', it's just a matter of 'how soon' - and the sooner the better for all of us," said International Energy Agency (IEA) Executive Director Fatih Birol.
