Enhanced policy support such as the US Inflation Reduction Act, which has provided $369b of subsidies and tax credits for clean energy technologies, has also helped, the report said.
As a result, the IEA expects annual clean energy investment to jump by 24 per cent compared with 2021, while spending on fossil fuels will rise by 15 per cent, it added.
Solar power is the “star of global energy investments”, with total spending in 2023 forecast to reach $382b, exceeding the $371b expected to be spent on oil production, said Birol. In 2013, $636b was spent on oil production and $127b on solar power.
The IEA chief attended the recent G7 summit in Japan and said he was encouraged by the level of alignment on energy matters between G7 members and invited countries such as Brazil, India and Indonesia. “I had rarely seen such a homogeneous view of the future of energy markets.”
But to maintain the momentum, G7 leaders needed to ensure that spending on clean energy was broadened to more emerging and developing countries, said Birol.
“If there is one challenge it is whether or not the emerging countries will be able to finance their clean energy transition alone.”
Despite the boom in clean energy spending, global energy-related carbon emissions grew 0.9 per cent last year to a record 36.8b tonnes, the IEA said in March.
Birol also called on national and international oil companies to direct more of their spending towards low-carbon energy solutions. Total investment by the oil and gas industry on low-emissions sources of energy is less than 5 per cent of the total spent on fossil fuel production, according to IEA analysis.
“I hope that there is more of a parallel between what the heads of the international and national oil companies say about their concerns about climate change and what they do in terms of their investment,” said Birol.
