Brief

ProfStrachan notes that global solar capacity hit 3 TW in 2026—following 1 TW in 2022 and 2 TW in 2024—highlighting the long ramp since the 1954 silicon solar-cell invention. He emphasizes China’s dominance (over half of installations), its doubling of battery storage in 2025 per Ember, and storage expansion targets in its latest Five-Year Plan.

Why it matters

Global solar capacity reached a third terawatt (3 TW) in 2026, after the world reached 1 TW in 2022 and 2 TW in 2024; the silicon solar cell was invented in 1954 and it took nearly seven decades to reach the first terawatt.

Key details

  • Bloomberg reported the recent additions; ProfStrachan cites that China is responsible for more than half of all global solar installations and, according to Ember, doubled its battery storage capacity last year (2025).
  • China’s latest Five-Year Plan explicitly targets ramping renewables by deploying additional storage, positioning China ahead in the clean-energy race relative to Europe and the United States.

Extraordinary: 'The World Adds a Third Terawatt of Solar Power'.

"It took nearly seven decades, after the invention of the silicon solar cell in 1954, for the world to install 1 terawatt of solar capacity, conceivably enough to power the entire United States."

"After passing that milestone in 2022, the world added its second terawatt in 2024 and its third in 2026, Bloomberg reports."

And what about China?

"China, which is responsible for more than half of all solar installations globally, doubled its battery storage capacity last year, according to data from energy think tank Ember."

"And in its latest Five-Year Plan, it set a goal to ramp up the use of renewable energy by deploying yet more storage."

Off the charts!

So where does that leave Europe and the United States in the clean energy race?
