Global Energy Transition Tracker

How fast is the world shifting to clean energy—and what could still stall it?

Twelve story-driven chapters: where the money flows, how fast electrons turn green, what AI does to the grid, and which bottlenecks decide 2030. Styled like a long-form infographic—timelines, comparison bars, and “one-glance” charts.

Illustrative figures are labeled. Not investment, trading, or policy advice—context for the transition story.

The Money River: Who Pays for the Transition

Think of clean power as the world’s largest infrastructure bill—paid every year. Through 2025–26, capital is still concentrated: a handful of economies deploy most hardware, while emerging markets finance a growing share of new coal and gas unless concessional money and grids arrive first.

If you only remember one slide from this chapter: solar and grids are the twin engines—panels are cheap; permission-to-plug-in is not. The doughnut is a headline; the queue lengths in Chapter 10 are the footnote that moves markets.

Electrons Turn Green Faster Than Molecules

Electricity is the front line. Wind and solar are climbing toward one-fifth of global generation by 2026 on mainstream outlooks, while coal’s share keeps sliding—slowly in absolute terawatt-hours in some regions, quickly in others. The catch: transport, industry, and heat still burn fossils; “green electrons” can mask brown molecules.

Coal (counter-trend)12 (weak/flat)
“The chart that matters is not “installed capacity”—it is “kilowatt-hours delivered when demand peaks.””

The Great Plateau: CO₂ Still Stubborn

Energy-related CO₂ has been flirting with a plateau near the high 30s of gigatonnes: advanced economies bend the curve with efficiency and renewables; many emerging economies add emissions as they industrialize. Early 2026 is a tension point—policy tightens in some capitals while defense spending and new industrial reshoring add energy hunger elsewhere.

Why “net zero” charts still feel far away

Cleaning power is not the whole game: cement, steel, and chemicals need heat and carbon chemistry. Until those curves move, the atmosphere sees a plateau even when headlines scream “record solar.”

The Price on Carbon Goes Retail

Compliance markets (EU ETS, UK, Korea, China’s national scheme) set the tone for heavy industry. Voluntary markets splinter into project quality tiers. By early 2026, CFOs treat carbon like FX exposure—hedged where liquidity exists, “shadow priced” everywhere else.

EU ETS€70–95 / t band (volatile)Steel, cement, power, aviation (CORSIA overlap)
