Solar power surged 14%, filling the gap before coal could spike
In March 2026, as conflict in West Asia shuttered the Strait of Hormuz and rattled global energy markets, India and six other major economies responded not with a retreat to coal but with a quiet demonstration of renewable resilience. Solar and wind generation absorbed the shock that fossil fuels could not, revealing that years of patient infrastructure investment had built something more durable than a power grid — a buffer against geopolitical disruption. India's ascent to third place globally in renewable capacity suggests the energy transition is no longer a distant aspiration but an unfolding reality, advancing steadily beneath the noise of crisis.
- The closure of the Strait of Hormuz sent fuel costs spiraling and exposed how deeply global power systems remain entangled with geopolitical instability.
- Conventional logic predicted a coal surge — instead, fossil fuel generation fell in seven major economies, with coal down 3.5% and gas down 4% year-on-year in March.
- Solar power leapt 14% and wind 8% globally, with India's booming solar sector emerging as the single largest force displacing fossil fuel consumption in the country.
- India added 55.3 GW of renewable capacity in FY2025-26, vaulting to third in the world and proving that prior investment, not crisis improvisation, determined who weathered the shock.
- Seaborne coal trade volumes sank to their lowest since 2021, signaling that the physical arteries of the fossil fuel economy are quietly narrowing.
In March 2026, the closure of the Strait of Hormuz sent shockwaves through global energy markets — and produced an outcome few had anticipated. Rather than triggering a scramble for coal, the supply disruption coincided with a measurable decline in fossil fuel power generation across seven major economies, including India, the United States, Germany, and Turkey. The Centre for Research on Energy and Clean Air, tracking electricity data from nations representing the vast majority of global coal and gas capacity, documented the shift in a report released Wednesday.
The numbers defied conventional wisdom. Coal-fired generation fell 3.5% globally compared to March of the previous year, while gas dropped 4%. China was the sole exception, with fossil output rising 2%. Everywhere else, the gap was filled not by rationing or emergency measures, but by renewable energy — solar up 14%, wind up 8%, with modest hydropower gains partially offset by a decline in nuclear output.
India's story was especially striking. Solar power was the primary driver of the country's fossil fuel displacement, underpinned by 55.3 gigawatts of new renewable capacity added during FY2025-26 — enough to place India third globally, behind only China and the United States. That infrastructure had been years in the making, but its timing proved fortuitous: when energy supplies tightened, India had the capacity to absorb the blow without reverting to coal.
Lauri Myllyvirta, the center's lead analyst, described the moment as a turning point, arguing that renewable energy had demonstrated it could function as a genuine buffer against geopolitical shocks — not just a climate solution, but a strategic one. Seaborne coal trade volumes fell to their lowest since 2021, a quiet signal that the fossil fuel economy's physical infrastructure is contracting. The transition, it seems, is advancing not through dramatic declarations, but through the steady accumulation of turbines and solar panels coming online across the world.
In March, something unexpected happened across seven major economies. As military conflict in West Asia forced the closure of the Strait of Hormuz and sent shockwaves through global energy markets, India joined the United States, Turkey, South Africa, Germany, and the Netherlands in watching their fossil fuel power generation decline. The Centre for Research on Energy and Clean Air, a think tank tracking real-time electricity data from countries representing 87% of global coal generation and over 60% of gas-fired capacity, documented the shift in a report released Wednesday.
The numbers told a story that contradicted what many energy analysts had predicted. When supply lines tighten and fuel becomes scarce, conventional wisdom suggests nations would burn more coal to compensate. Instead, the opposite occurred. Coal-fired power generation fell 3.5% globally in March compared to the same month last year, while gas-fired generation dropped 4%. China was the lone exception, with fossil fuel output rising 2%, but across the rest of the tracked nations, the trend held firm.
What filled the gap was not rationing or crisis management, but renewable energy. Solar power surged 14% year-on-year, while wind generation climbed 8%. Hydropower added a modest 2%, though nuclear power declined enough to offset some of those gains. The growth in clean electricity proved substantial enough not merely to replace lost fossil fuel capacity but to prevent the energy crisis from triggering a spike in coal consumption—the outcome most observers had anticipated.
India's experience mirrored this global pattern with particular clarity. Solar power emerged as the single largest factor driving down the country's reliance on fossil fuels. The nation had added 55.3 gigawatts of renewable energy capacity during the fiscal year ending March 2026, a figure that elevated India to third place globally in renewable capacity, behind only China and the United States. This expansion was not a response to the Hormuz crisis; it reflected years of policy commitment and investment. But the timing meant that when energy supplies tightened, India had the infrastructure in place to weather the disruption without reverting to coal.
Lauri Myllyvirta, lead analyst at the research center, framed the moment as a turning point. The record growth in clean power generation had done more than offset the fossil fuel crisis—it had demonstrated that renewable energy could serve as a genuine buffer against geopolitical shocks. Yet Myllyvirta also issued a broader call: the current emergency should accelerate, not merely inform, the global energy transition. The data showed that renewable capacity could respond to crisis, but only if nations continued building it aggressively.
Seaborne coal transport volumes fell 3% in March, reaching their lowest point since 2021, a sign that even the physical infrastructure of fossil fuel trade was contracting. The report's findings suggested that the energy world was shifting beneath the surface—not through sudden policy shifts or dramatic announcements, but through the steady accumulation of solar panels and wind turbines coming online across continents. India's position as a top-three renewable power builder meant it was not merely a participant in this transition but increasingly a driver of it.

A Conversa do Hearth Outra perspectiva sobre a história
Why did fossil fuel generation fall when energy supplies were actually constrained? Wouldn't scarcity push nations toward coal?
That's the intuition most analysts had. But India and six other countries had already built enough solar and wind capacity that they didn't need to. When the Hormuz closure hit, they had alternatives ready.
So this wasn't a sudden shift—it was infrastructure that was already there?
Exactly. India added 55 gigawatts of renewable capacity in a single fiscal year. That's not an emergency response. That's years of policy and investment paying off at the precise moment it mattered most.
What does it mean that solar was India's primary driver, not wind or hydro?
Solar is scalable and fast to deploy. It's the technology that's been improving most rapidly in cost and efficiency. When you need to displace fossil fuels quickly, solar is what does the work.
The report says this contradicted expectations. What were people expecting to happen?
A coal spike. The thinking was: close the Hormuz, squeeze energy supplies, nations panic and burn more coal. Instead, clean power was already large enough to absorb the shock.
Does this mean the energy transition is now resilient to geopolitical crises?
It's more resilient than it was. But only in countries that invested heavily in renewables beforehand. The lesson is that you have to build the capacity before the crisis hits, not after.
