After defying projections, solar power is now overtaking nuclear as a global power source, marking a significant shift in the energy landscape. A decade ago, solar barely registered, providing just 1% of the world's power. By 2026, it is projected to reach 10% and surpass nuclear, a mainstay since the late 1970s.
Ember co-founder Dave Jones calls the statistic of solar generating more electricity than all nuclear plants "pretty insane." Solar has become the fastest-growing source of new electricity in history, meeting three-quarters of the world's electricity demand growth in 2025. Its rise has been driven by dramatically falling panel costs, with prices well under $100 and lasting 30-40 years without input. China remains the world's biggest solar power, though its internal boom is slowing; however, cheap solar exports continue to increase.
In Australia, over four million homes have rooftop solar, covering well over a third of households. In sun belt countries like Pakistan and Nigeria, solar's growth is driven by households affording panels without loans, offering independence from utilities during uncertain times. The battery revolution has been crucial, allowing solar plus storage to be routinely cheaper than new fossil plants in sunny regions, solving the problem of shifting midday sun into the evening.
Despite barriers to long-term storage, solar's momentum appears unstoppable as it cements its role as the engine of the global power transition.
