The Currency of the Future Is Electricity: Why India's Race for 75% Renewable Energy Will Be a Race for Cheaper Power.....

Introduction: From Oil Economics to Electricity Economics

The next great competition between nations may not be about who possesses the largest oil reserves, the strongest currency or the cheapest labour, but who can produce and deliver electricity at the lowest possible cost. This is the larger significance of Elon Musk's observation that electricity could become the currency of the future. The idea is not that money will disappear, but that economic value will increasingly be determined by access to affordable, reliable energy. Artificial intelligence, electric vehicles, robotics, data centres, industrial production, agriculture and even household living standards will depend on the cost of electricity. India targeting 75% renewable electricity would therefore be more than an environmental commitment: it could become a strategy for improving industrial competitiveness, reducing import dependence and lowering the cost of living. However, the proposition needs an important qualification: renewable energy alone does not guarantee cheaper electricity. Storage, transmission, grid flexibility and dependable backup will determine whether the transition delivers its promised economic benefits.

Why 75% Renewable Energy Could Transform India

India has a strong economic reason to accelerate renewable energy. It imports substantial quantities of coal, oil and natural gas, exposing domestic production and household purchasing power to international commodity prices, currency depreciation and geopolitical disruptions. Solar and wind energy, once installed, do not require continuous fuel purchases. This changes the structure of electricity costs: the initial investment becomes more important, while exposure to volatile fuel prices declines. India's solar power tariffs have demonstrated this potential, with competitively auctioned projects frequently achieving prices around ₹2.5–3 per unit, although these figures do not represent the complete cost of round-the-clock electricity. India's installed renewable capacity, including large hydropower, has crossed 250 GW in 2025, demonstrating the scale of the transition already underway. The government has also established a 2030 target of 500 GW of non-fossil electricity capacity. A 75% renewable share in electricity generation would be considerably more ambitious than simply reaching an installed-capacity target, because generation depends on actual utilisation, weather conditions and the availability of storage.

Testing the Environmental Benefits: Can Emissions Really Fall?

The environmental argument is particularly strong because India's electricity sector remains heavily dependent on coal. According to Ember's Global Electricity Review 2026, coal supplied approximately 71% of India's electricity generation in 2025, while clean sources contributed 27%. The carbon intensity of electricity was around 670 grams of CO₂-equivalent per kilowatt-hour, compared with a global average of 458 grams. India's power-sector emissions were approximately 1,395 million tonnes of CO₂-equivalent in 2025. These figures illustrate the potential gains from replacing coal generation with renewable electricity. If India progressively achieves a 75% renewable share in electricity generation, it could substantially reduce carbon emissions, particulate pollution, sulphur dioxide and nitrogen oxide emissions associated with fossil-fuel power plants. It would also reduce water consumption associated with conventional thermal generation. Nevertheless, the reduction would depend on which sources are displaced. Replacing coal with solar and wind delivers greater direct emissions savings than replacing existing hydropower or nuclear generation. Furthermore, manufacturing solar panels, batteries and transmission equipment also involves emissions. The correct measure is therefore lifecycle emissions rather than treating renewable electricity as entirely emission-free.

The Economics of Cheaper Energy: What Recent Studies Reveal

The strongest evidence supporting India's renewable ambitions comes from the changing economics of electricity production. The International Renewable Energy Agency's 2025 report, examining 2024 costs, found that 91% of newly commissioned utility-scale renewable capacity produced electricity more cheaply than the cheapest new fossil-fuel alternative. Globally, the weighted average cost of new onshore wind was approximately 3.4 US cents per kWh and solar photovoltaic electricity 4.3 cents. Battery storage costs had declined by 93% between 2010 and 2024, reaching approximately $192 per kWh of installed storage capacity. India is particularly well positioned to benefit from these developments. An April 2026 Ember study estimated that solar combined with batteries could theoretically meet 90% of Indian electricity demand at a levelised cost of approximately ₹5.06 per unit. Its modelling suggests that seven of India's ten largest electricity-consuming states could obtain at least 90% of their demand through this combination at competitive costs. Even more significantly, solar and battery auctions in 2025 and early 2026 discovered tariffs around ₹2.9–3.5 per unit for certain projects. These are important developments, although auction tariffs and modelled generation costs should not be confused with the final delivered cost of electricity, which includes transmission, distribution, financing and reliability requirements.

Why Electricity Could Become the Currency of the Future

Musk's argument becomes more understandable when viewed through the economics of artificial intelligence and automation. Electricity is the fundamental input behind almost every emerging productivity-enhancing technology. An artificial intelligence data centre consumes enormous quantities of electricity to train and operate computing systems. Electric vehicles convert electricity into mobility, while robots use it to manufacture goods, transport materials and perform services. Green hydrogen can convert renewable electricity into an industrial fuel, potentially reducing dependence on fossil fuels in steel, fertilisers and shipping. Even agricultural productivity increasingly depends on affordable electricity for irrigation, refrigeration, processing and transportation. Consequently, the cost of electricity influences the cost of producing almost everything else. A country with cheaper and more dependable electricity can attract investment, manufacture at lower costs and offer more competitive products internationally. In this sense, electricity becomes an economic currency: not a replacement for rupees or dollars, but a measure of the productive purchasing power available to households and businesses. The household that spends less on electricity has more disposable income, while the manufacturer with cheaper power has greater room to reduce prices or increase profits. As automation expands, the cost of energy may become as important to economic competitiveness as the cost of labour.

The Competition Ahead: Who Can Produce the Cheapest Reliable Electricity?

The competition will increasingly be between countries that can combine cheap generation with reliable electricity around the clock. China has established a considerable advantage through its dominance of solar panels, batteries and critical mineral processing. India has an opportunity to become a competing manufacturing centre rather than remaining dependent on imported energy technologies. According to the International Energy Agency's India Renewable Energy Market Report 2026, India auctioned 15 GW of hybrid renewable projects during 2025, the largest annual procurement of its kind globally. The average tariffs achieved between 2023 and 2025 were approximately $45 per MWh, around 20% below the average cost of coal-generated electricity in 2025. However, the competition is not simply about producing the cheapest solar panels. It is about developing batteries, pumped hydro storage, smart grids, high-voltage transmission, domestic manufacturing and technologies that can supply electricity when sunlight and wind are unavailable. The IEA also forecasts that India's electricity demand will grow by an average 6.4% annually through 2030. This makes investment in reliable electricity infrastructure essential.

The Reality Check: Is 75% Renewable Electricity Achievable?

India has already crossed an important milestone, with non-fossil sources accounting for approximately 54% of installed electricity capacity by July 2026. However, installed capacity is not the same as actual electricity generation. The IEA's 2026 outlook projects that renewables will contribute just over one-third of India's electricity generation in 2030. Therefore, achieving 75% renewable generation requires a much more ambitious transformation than the existing 500 GW non-fossil capacity objective. It requires accelerated storage deployment, modernised transmission, flexible demand, stronger electricity distribution companies and investment in domestic battery supply chains. It also requires recognising that some industrial processes and periods of peak demand will continue to need dependable dispatchable power. Nuclear, hydropower and other low-carbon sources can complement solar and wind. Moreover, poorly designed storage auctions and expensive financing can undermine the apparent cost advantage of renewable electricity. The transition must therefore be judged by the cost of reliable electricity delivered to consumers, not merely by the number of renewable projects commissioned.

Conclusion: The Future Belongs to the Cheapest Energy Producer

India's ambition to reach 75% renewable electricity should be understood as an economic and industrial strategy as much as an environmental objective. Cheaper electricity can reduce production costs, improve household purchasing power, strengthen the rupee by reducing fossil-fuel imports and attract investment in artificial intelligence, electric mobility and advanced manufacturing. It can also reduce carbon emissions and improve public health. The real opportunity is to create a virtuous cycle in which cheaper renewable generation attracts investment, greater investment expands manufacturing capacity, technological improvements reduce storage costs and increasingly affordable electricity stimulates productivity. The decisive competition of the coming decades will not necessarily be between countries possessing the largest energy reserves, but between countries capable of converting natural resources, technology and capital into the cheapest reliable unit of electricity. India's 75% ambition is demanding, but the economic logic is compelling: in an increasingly automated world, the nation that makes energy cheapest could make almost everything else cheaper too.

The central distinction throughout this analysis is between renewable installed capacity, renewable electricity actually generated and the final cost of reliable electricity delivered to consumers. The 75% figure is an ambitious proposed target, not an existing Indian government commitment.
