The Transition That Never Transitioned: Fossil Fuels Still Powered 86% of the World in 2024

What 2000–2024 energy history actually shows.

Global energy supply increased 2% in 2024 driven by rises in demand across all forms of energy,
with non-OECD countries dominating both the share and annual growth rates.
Fossil fuels continue to underpin the energy system accounting for 86% of the energy mix.

A quarter-century of promises

It’s November 2025. We are exactly a quarter century removed from the millennial panic, the Kyoto Protocol hype, and the first waves of “irrevocable tipping points” that were supposedly coming in 10 years (i.e., 2010).

We were told that fossil fuels had to be phased out immediately, or the planet would warm by 5–6°C by 2100. 25 years, multiple trillions of dollars, millions of wind turbines and solar panels, and countless “last chance” climate summits later…

Fossil fuels supplied ~88% of global primary energy in 2000.
In 2024, they supplied 86%.

Let that sink in.

After a quarter century of the most expensive industrial policy in human history, the share of fossil fuels in global energy has declined by a whopping 2 percentage points.

The “energy transition” is a joke. Net Zero is delusional.

And the original justification, catastrophic 5°C warming, has quietly been abandoned even by the IPCC’s own models (now closer to 2–2.5°C, maybe 3°C in the very highest scenarios that nobody actually expects).

The gentle warming we’ve experienced (≈1.3°C since pre-industrial) has coincided with:

The Energy Institute’s annual scoreboard

But the new Energy Institute (EI) 2025 Statistical Review (data through 2024) is brutal for the narrative. Global energy demand hit another all-time high… Fossil fuel consumption hit another all-time high… CO₂ emissions hit another all-time high.

Wind + solar grew by a record amount… and still only supplies ~6% of primary energy. The “transition” isn’t displacing fossil fuels; it’s just adding on top to meet Asia’s insatiable demand for cheap, reliable energy.

The EI Statistical Review is the global energy scoreboard, published annually since 1952 and now in its third year under the Energy Institute’s custodianship. EI is a pro-net-zero professional body, not a skeptical shop, which makes their own framing this year especially revealing: they describe today’s world as a period of “energy addition,” where renewables grow fast but alongside record highs in coal, oil, and gas.

However, countries that bet heaviest on unreliables are paying the price. Remember the April 28, 2025 Iberian Peninsula blackout? Spain and Portugal — Europe’s poster children for “renewable leadership” (≈50% wind+solar in electricity on good days) — suffered the continent’s largest blackout in decades.

No storm. No heatwave. No cyberattack. Just too much intermittent generation, not enough inertia, and grid operators lost control in seconds. Millions in the dark, airports shut, hospitals on generators, trains stopped. I covered it here:
Spain & Portugal Blackout – A Warning from the Future of Energy

At approximately 12:30 p.m. local time, Spain’s national electricity grid suffered a
sudden loss of about 15 gigawatts—around 60% of the country’s power consumption
at that moment. This abrupt drop led to a cascading failure across the grid, plunging
Spain, Portugal, and parts of France and Andorra into darkness.

While we subsidise our solar panels into existence with coal-fired factories, China started construction on 94.5 GW of new coal plants in 2024, the highest level in a decade. They commissioned another 30.5 GW.

They now burn more coal than the rest of the world combined, export the green tech, keep prices low, and watch the West deindustrialise itself. I wrote the definitive thread on this:
China’s Coal Paradox: Driving Renewables Abroad While Burning Coal at Home

Oh, and in case you thought this was “market-driven,” solar got 205× more federal subsidies per unit of energy produced in the US (2010–2019) than oil and gas.

Clearly, solar has received the most subsidies per unit of electricity because it is one of
the largest recipients of subsidies while producing the second least amount of
electricity since 2010. Wind is second on this list because, while it produced more
electricity than solar, it is still a small part of the U.S. electricity mix. Nuclear and fossil
fuels generate much more electricity relative to the subsidies they received, which
indicates they are less dependent on subsidies for their revenue and profitability than
wind and solar. Source: Federal energy subsidies in the USA…

The 2025 Energy Institute review is 76 pages of charts that all tell the same story:
The era of fossil fuels is not ending. It’s barely even bending.

The US State Department issued a joint statement denouncing Net Zero policies for global marine shipping as a 'global carbon tax,' says Friends of Science Society. Small Pacific Islands requested an International Court of Justice (ICJ) advisory statement on climate obligations claiming existential crisis; but many hypocritically provide marine registry services.

The DOE climate report: a scientific milestone that Europe does not want to see

While alarmist studies are spreading like wildfire in Europe, the groundbreaking report A Critical Review of Impacts of Greenhouse Gas Emissions on the U.S. Climate is being completely ignored. This report finally pays explicit attention to uncertainties, alternative insights, and factual observations in climate science. The European silence is not only remarkable, it is downright shocking. It casts a shadow over the intellectual honesty of the European climate debate.
