Growth rate slightly lower than previous first-half years but sector still strong and resilient, experts say
Investment in renewable energy has continued to increase around the world despite moves by Donald Trump’s White House to cancel and derail low-carbon projects.
In the first half of 2025, investment globally in renewable technologies and projects reached a record $386bn, up by about 10% on the same period last year.
Investment in energy around the world is likely to hit about $3.3 trillion (£2.4tn) this year. While more than $1tn of the total is still likely to flow into fossil fuels, double that amount – about $2.2tn – is expected for low-carbon forms of energy.
A report from the Zero Carbon Analytics thinktank, published on Tuesday, shows that the rate of increase in renewable energy investment has not slowed significantly. Between the first half of 2023 and of 2024, the total increased by 12% and from 2022 to 2023 the increase was 17%.
