The good and the bad news on clean energy


Hey Reader, welcome to The Energy's weekly data newsletter. This week we dive deeper into the latest data on global energy investment from the International Energy Agency.

Good and bad news in clean energy

In good news for all bar the LinkedIn warriors still second guessing the clean energy transition, global investment in clean energy is outstripping traditional fossil fuels by a widening margin, led by China’s solar and battery boom.

But in bad news for everyone – whether they recognise it or not – investment in fossil fuels remains sticky as China continues to take out insurance against power shortages in the form of coal power and the US backslides on climate commitments.

The International Energy Agency’s World Energy Investment 2025 offers a frustrating snapshot of a global energy transition proceeding at a “two steps forward, one step back” pace, with too many nations hedging their bets.

It is accelerating but not quickly enough to meet the world’s 2015 Paris commitments to the keep global temperature increase from pre-industrial levels “well below” 2 degrees Celsius and preferably below 1.5C, which the world blasting through.

And that’s bad news for the world’s most vulnerable people, as a cascade of extreme weather events that disproportionately hurt them attests.

China dashes ahead

It’s no surprise that China’s investments in renewable energy, nuclear power, grids and storage are setting a cracking pace, at more than twice the rate of the United States and the European Union, the second and third largest clean energy investors.

Plummeting prices for solar panels, batteries and — until a few years ago when supply chains seized up and inflation took hold — wind turbines have triggered a near doubling of investment worldwide in the past five years.

Investment in solar power is expected to hit $US450 billion in 2025, — almost a third of total investment in the power sector. Large strides — albeit from a lower base — are also being made in India, Africa and Southeast Asia. Meanwhile, China is the only producer of wind turbines bending the cost curve downwards on that technology.

A surprising upstart — Pakistan — came from nowhere to import 19 gigawatts of solar panels from China in 2024, as the country's energy users revolted against corrupt and incompetent state-linked power companies.

Thermal power is dwarfed by renewables

Another surprising thing in light of the febrile debate on the energy transition during Australia’s recent election campaign and around the world is how small investment in thermal power is relative to renewables.

Thermal power involves the use of coal, gas and nuclear energy to boil water and create steam to drive turbines. As the chart below shows, thermal power from these sources is dwarfed by spending on renewables, and battery storage is expanding rapidly from a low base.

Total investment in the global power sector, including grids, was nearly $US1.5 trillion in 2024, up by more than half since COVID struck in 2020, and fossil fuel power accounted for less than a seventh of the total.

This pattern is repeated more or less across ideological borders, something to bear in mind when proponents of a return to traditional “baseload” power bend your ear on social media or at the pub.

Marring this picture, the share of investment going to emerging and developing economies has fallen from nearly 30 per cent a decade ago to just above 20 per cent, a yardstick for the failure of rich economies to stump up enough affordable finance.

Batteries rival gas power

Investment in batteries has come from negligible levels just five years ago to nudge closer to investment in gas power generation with $66 billion expected to be invested in the storage technology this year.

That’s significant because batteries and gas peaking plants compete with each other to firm wind and solar power when the sun goes down or the wind doesn’t blow. And Australia is a big player in batteries, with a 10 GW-plus development pipeline.

It’s true that batteries aren’t yet economical for longer duration duties such as prolonged wind and solar droughts of a week or more, where gas peakers will be required for years — perhaps decades — to come.

But they could push gas peakers’ out of regular daily firming power duties, undermining the economics for their investors and pushing governments to ponder alternative support mechanisms.

Low emissions fuels still a rounding error

On the downside, total investments in oil, coal and gas are not falling quickly enough, while investments in low emissions fuels such as biomethane and green hydrogen remain tiny in comparison.

Oil and gas companies invested around $US22 billion in low emissions energy technologies in 2024, around 25% less than in 2023, the IEA says. Majors have revised low-emissions targets down sharply, and another 10% fall is on the cards for 2025.

New players, including national oil and gas companies, are stepping in to fill the breach, but the trend is discouraging because low emissions substitutes for oil and gas are needed urgently to decarbonise shipping and aviation.

Expert view

Australia is absolutely walking both sides of the street, as we saw with the Albanese government's approval of a 40 year extension on the North West Shelf gas processing plant. We are still a major, top three fossil fuel exporter. The incumbent industry is still very powerful politically in Australia, and that undermines Australia's long term strategic national interest, in my view.
It is definitely two steps forward, one step back at best. But we have seen Australia is going to be a major beneficiary of the massive scaling up of batteries, solar, wind and EVs — we get the benefit of dramatically lower costs. And although batteries, as yet, haven't seen massive deflation, for example, in the residential market, it's only a matter of time.
The IEA reports that the world continues to electrify and decarbonise. Power sector investment reached a new high of US$1.5 trillion in 2024, driven primarily by record investment in sources of low-emissions generation, as well as grids and battery energy storage systems (BESS).

Upstream oil & methane investment is set to fall for the first time since 2020 by 4% globally. Follow the money, not the vested interests' claims.

The IEA forecasts global BESS (utility scale plus behind the meter) investments in 2025 will triple that of 2022, and is set to reach the level of global methane-fired power capacity investment this year.
