Mukesh Ambani, chairman of Reliance Industries, has announced India’s largest-ever share sale, raising £12bn in a move that signals a decisive pivot towards renewable energy and technology. The rights issue, which opened today, is a calculated bet on the decarbonisation of one of the world’s fastest-growing economies.
For context, India’s energy landscape is a paradox. The nation accounts for 7% of global carbon emissions, yet its per capita emissions are a third of the global average. With a population of 1.4 billion, the pressure to industrialise without replicating the West’s fossil-fuel trajectory is immense. Ambani’s play is not just corporate expansion; it is a structural shift in how India powers its future.
The capital will be directed towards Reliance’s new energy business, which includes solar photovoltaic manufacturing, battery storage, and green hydrogen production. The company aims to build 100 GW of solar capacity by 2030, equivalent to the total installed power capacity of France. This is a staggering ambition, but the numbers reflect the physical reality: India receives 300 sunny days a year, an insolation rate that makes solar inevitable.
Critics argue that Reliance’s hydrocarbon legacy cannot be erased overnight. The conglomerate still operates the world’s largest oil-refining complex in Jamnagar, Gujarat, and its petrochemical division remains a cash cow. But the share sale’s magnitude suggests a deliberate strategy: use fossil-fuel profits to finance the transition. It is a carbon levy by another name.
Ambani’s timing is astute. Global investors are starved of yield. Central banks, from the Federal Reserve to the European Central Bank, have kept interest rates low, pushing capital towards riskier assets. Reliance offers a rare combination of scale, diversification, and perceived stability. The £12bn sale is more than a record; it is a stress test of the market’s appetite for emerging-market green investments.
The environmental implications are profound. India’s energy demand is projected to double by 2040. Without a massive build-out of renewables, that demand will be met by coal, which already provides 70% of the country’s electricity. Ambani’s 100 GW solar target, if realised, would displace roughly 200 million tonnes of coal per year. To put that in perspective, it is the equivalent of removing 50 million cars from the road.
But the technology is only half the story. The share sale also funds Reliance’s 5G network and digital services, creating a feedback loop between data, energy, and logistics. Smart grids require real-time communication; electric vehicles need charging infrastructure. Ambani is building the skeleton of a low-carbon economy.
The risks are non-trivial. India’s regulatory environment is volatile. Land acquisition for solar farms can be politically fraught. And the green hydrogen economy is still nascent, with costs currently triple that of grey hydrogen made from natural gas. Yet, Ambani’s track record suggests he is willing to underwrite long-term bets. His entry into telecommunications in 2016 with Jio disrupted the market and now commands over 400 million subscribers.
What does this mean for the global climate fight? It demonstrates that private capital can be mobilised at scale for decarbonisation. But it also underscores the disparity between developed and developing nations. India’s per capita solar capacity is a tenth of Germany’s. The Ambani sale, while historic, is a drop in the ocean of the world’s annual energy investment needs of £3tr.
In the end, this is a story of economic inevitability. As the cost of solar falls below coal and the cost of batteries falls below gas, the physics of the energy transition dictates that capital will follow. Ambani is not acting out of altruism. He is positioning Reliance for a world where carbon is a liability. For India, the £12bn sale is a down payment on that future.
