Two reports published this week, one from the International Energy Agency and one from UK-based think tank Ember, land on the same headline: solar power grew faster than any other fuel source from 2024 to 2025. That growth is being driven in large part by China and India, two of the world's biggest carbon emitters, both of which have become the dominant players in solar production and deployment. The notable detail in the data is that neither country needed to burn more fossil fuels to meet rising electricity demand. Investment in solar scaled fast enough that clean generation absorbed the gap.
The CBC's Anand Ram, reporting on both releases, highlights one figure that puts the scale of solar growth in concrete terms: total global solar output is now sufficient to cover the entire electricity consumption of the European Union, all 27 member states. Beyond solar specifically, renewables as a combined category have reached a point where they can absorb all new electricity demand worldwide year over year. That means additional consumption growth, which has continued to rise globally, no longer requires new fossil fuel projects to meet it. The reports coincide with renewed attention on energy security following disruption near the Strait of Hormuz, which has reminded countries dependent on oil and gas imports exactly how exposed that dependency makes them.
Jessica Isaacs of the World Resources Institute describes the structural problem clearly: a country that imports fossil fuels is carrying a permanent drag on its public finances from something it cannot control. Switching to domestic renewable electricity is one way to remove that exposure. Pakistan is the example she points to. The country has made substantial gains in solar production over the past several years and, according to World Resources Institute estimates, avoided roughly $12 billion in costs that the current Iranian oil disruption would otherwise have imposed. Pakistan still depends on Iranian oil and natural gas, so the buffer is partial. But the savings figure shows how much financial protection even a partial transition can create. Pakistan is also a country where the stakes of climate change are not abstract: devastating floods in recent years, described by scientists as intensified by warming, killed large numbers of people and drove home why reducing dependence on fossil fuels serves multiple purposes at once.
Bottom line: The IEA and Ember numbers confirm something that has been building for years but is now quantifiable: renewables are no longer a supplement to the fossil fuel system. They are absorbing global demand growth. The geopolitical case, illustrated by Pakistan's $12 billion cushion, is starting to look as straightforward as the environmental one.
