380 GW of new solar power has been installed globally in the first six months of 2025; 64% up on the same period last year. GWEC projects that 2025 will see 139 GW of new wind installations. Assuming solar keeps increasing at the near rate in the second half of 2025, the total renewables figure for 2025 will top 1,000 GW for the first time ever. Even if solar slowed down to half its current rate of growth, that will still be true.
Three times the entire global nuclear capacity. Let that sink in. That took decades to build. Now renewables can do three times more in just one year.
Consider something else. Renewables growth has years, if not decades, of further growth ahead of it. Economies of scale mean that as more of it gets built, it keeps getting cheaper. And it's already the cheapest electricity there is. When will the first 2,000 GW year be?
And when converted to wh not just w it’s even worse.
