After crossing the 100-gigawatt mark in 2012, it took the world 10 years to deploy 1 terawatt of solar power. An additional 1 terawatt, enough to meet all of US power demand at its peak, took less than three years to build. Not even two years later in 2026 — the precise timing is subject to debate among analysts — the 3-terawatt threshold was reached.
Some good news. And, naturally:
The first terawatt was mostly rich countries subsidizing the installation of solar, with China and poor countries still finding photovoltaics too expensive. That story changed going into the second and third terawatt, with China taking the baton from rich countries.
The current government of the United States is not going to get us out of climate change. The vanguard of modern communism, however, has a pretty good shot.
