My oped in today’s @the_hindu argues that India’s EV transition cannot succeed without a matching electricity-grid strategy. ⚡⚛️ Much of the public conversation around EVs focuses on scooters and passenger vehicles, but the deeper challenge lies in power infrastructure. Large-scale transport electrification, especially freight, logistics corridors, and depot charging, could add hundreds of TWh of electricity demand over time and fundamentally reshape India’s power system. The piece examines why EV adoption is ultimately not just a mobility transition, but also a generation, transmission, and distribution challenge. A key argument I make is that renewable energy alone cannot reliably support this scale of electrification without firm clean power backing the grid. That is where nuclear energy, including future SMR deployment near demand centres, becomes strategically important. The central point: India’s EV future will depend as much on building a resilient clean electricity system as on manufacturing vehicles themselves.

1 Heavy Goods Vehicle = Emissions & Energy Footprint of 25 Passenger Cars. That single statistic explains why India’s EV transition is not really about cars. It is about freight. Most public conversations around electrification focus on passenger EV adoption. But the real pressure on India’s future power system will come from supply chains, logistics hubs, and heavy transport. Electrifying India’s Heavy Goods Vehicle fleet alone could require 450–565 TWh of electricity annually, several times the projected demand from hundreds of millions of electric two-wheelers. When policymakers speak about electrifying roads, they are actually speaking about electrifying India’s industrial backbone. And that changes everything. Because EV adoption at this scale is no longer only an automotive challenge. It becomes: ⚡ A grid challenge ⚡ A distribution challenge ⚡ A baseload power challenge ⚡ A storage challenge ⚡ A national infrastructure challenge Without serious investment in grid readiness, smart charging, freight corridor planning, and clean firm power, electrification risks replacing oil dependence with coal dependence. India’s EV future will not be decided only by how many vehicles we manufacture. It will be decided by whether the grid can sustain industrial-scale electrification.

@catale7a FAKE NEWS ALERT ‼️

Warning❗️❗️❗️ Resident Indians, this is what Data Centers will do to your Water

@SupriyaShrinate It’s not a data centre specific problem, it’s a construction specific problem, in India when you drill a tubewell the ground water turns muddy sometimes, doesn’t mean you stop drilling tubewell.

Absolutely horrifying 🤯 This is how filthy the water has become in the United States for people living near Meta’s data centre. Water levels have dropped drastically, with very little pressure in the pipelines. Even people in rural areas are now forced to buy water not just for drinking but for bathing as well. Data centres require huge amounts of water for cooling. This is potentially what could happen to water resources in surrounding areas. India needs to be mindful of this before we build more data centres.

The muddy (brown/turbid) water reported by residents in Morgan County, GA, near Meta's Stanton Springs data center appears to be primarily suspended sediment, dirt and silt stirred up in their private wells. Residents link it to the data center construction (blasting, land clearing, earth disturbance) starting around 2018, which they say caused sediment to enter the groundwater, reduced water pressure, and damaged appliances. They now often use bottled water. Meta says an independent groundwater study found **no impact** from their construction or operations on local wells/residents' water. They source all water from the local utility (not groundwater). No public water tests in recent coverage mention chemical toxins or specific contaminants beyond sediment/silt. The EPA has pledged to investigate after AOC's hearing. Construction sites commonly cause temporary sediment issues if erosion controls aren't perfect; correlation is claimed but causation is disputed.

@grok @Acyn So even if there was any other construction than data centre the contamination would have been same as it’s construction problem than a DC problem.

AOC: This is what drinking water in Georgia looks like after Meta began data center construction in the community.

In the 1970s, nuclear was cheaper than coal. It was the cheapest, cleanest energy source on earth. Why didn't we just keep building more of it? 🧵

Electric vehicles face significant existing bottlenecks in India’s power sector. Without addressing them, the EV transition risks becoming little more than a temporary shift in energy dependence rather than a genuine solution. If incremental terawatt-hours come mainly from coal, India merely replaces oil dependence with coal dependence, importing from Australia and Indonesia instead of the Gulf, without emissions gains. The logic of electrification breaks if the grid is not cleaner than the fuel it replaces.

The real challenge of India’s EV transition ⚡🚛 isn’t selling electric vehicles — it’s building a power grid 🔌 capable of handling large-scale freight movement 🚚⚙️. The numbers are staggering! Full electrification of India’s 420M vehicles would require an additional 900 to 1,100 TWh of electricity per year. Even a moderate 50% fleet conversion by 2047 demands 500 TWh—equivalent to nearly a third of India’s current total generation. Despite their high visibility and political focus, 309 million electric two-wheelers would consume just 55–75 TWh. That is less than 7% of total projected EV demand. In short, the political visibility of scooters is inversely proportional to their actual grid impact. 🛵 The heavy lifting belongs to heavy goods vehicles (HGVs). One HGV emits as much as 25 cars. Electrifying India’s 6.26 million HGVs alone requires up to 565 TWh annually. When policymakers talk about "electrifying roads," they are really talking about supply chains. 🚛 Grids are stressed by instantaneous demand, not annual averages. Unmanaged evening charging could add several hundred gigawatts of peak load, risking grid instability and tariff spikes. To prevent this, smart charging capabilities must be mandated for all new chargers now. We also cannot simply swap oil dependence for coal dependence by importing coal from Australia or Indonesia to power EVs. For a truly clean transition, India needs a diversified energy mix: solar/wind, battery storage, and even micro modular nuclear reactors for highway corridors. The transition is inevitable; the grid must be made ready.

Hi @Spotify, nobody likes this.

Important piece in The Telegraph on why the Gulf crisis should be a wake-up call for India’s energy and infrastructure strategy. A strong case for combining renewables with reliable baseload power, including nuclear energy and SMRs, to build long-term resilience.

Every major infrastructure transition, highways, metros, digital payments, faced dysfunction before scale and performance. India’s nuclear sector is no different. The answer is better governance and execution, not abandoning the technology. My OpEd in The Telegraph today. telegraphindia.com/opinion/be-fut…

India cannot build a 21st-century economy on intermittent power alone. Renewables are essential, but energy security also requires reliable baseload capacity. My piece in The Telegraph argues that nuclear energy and SMRs must become part of India’s long-term infrastructure strategy. telegraphindia.com/opinion/be-fut…
