India blends 20% ethanol into every litre of petrol — and drivers are pushing back

Climate & Energy 3 min 54 sources

A national mandate to mix ethanol into fuel now covers every pump in India. The state gains — less imported oil, money to farmers — but the small daily cost lands on drivers who never chose it. Plus: Britain's green power stuck between approval and the grid, and the US EV moment slipping away.

Key takeaways

India now blends 20% ethanol into all its petrol, cutting imported oil and paying farmers — but drivers lose about 3–3.5% mileage and worry about older engines, a cost they didn't choose and can't avoid.
Britain has approved renewable projects at double the old rate, yet the power isn't flowing because the grid to carry it hasn't been built — approvals aren't the same as electricity.
Across India, Britain, and the US, the same lesson repeats: a clean technology can be ready while cost and timing still decide who gains and who pays.

Every litre of Indian petrol is now one-fifth ethanol

Fill up in India today and the fuel is E20 — petrol blended with 20% ethanol, an alcohol made from crops like sugarcane and corn. The mandate is national and near-complete, and this week it drew a public backlash [31]. Motorists on social media questioned whether older cars, designed for lower blends, would suffer corrosion, faster wear, or worse performance [31].

On Saturday the government and carmakers pushed back together. Maruti Suzuki, India’s largest carmaker, said it had serviced more than 15 million older cars over the past two years — vehicles never certified for E20 — and found no fuel-related problems [31]. Officials from Hero MotoCorp and Toyota Kirloskar Motor said even older vehicles run safely on the blend [31].

They did admit one trade-off. E20 cuts fuel efficiency by about 3 to 3.5%, because ethanol carries less energy per litre than petrol [31]. So a tank goes slightly less far. The industry’s answer is that ethanol’s higher octane lets engineers build future engines with higher compression, which could win the efficiency back and then some [31] — a benefit that lands on cars not yet built, while the mileage cost lands on cars already on the road.

Why India did this. Ethanol is home-grown; oil is imported. Blending it in cuts the crude India buys from abroad, keeps more money in the country, and pays domestic farmers for the crops. It also burns a little cleaner than straight petrol. The policy isn’t aimed at any one driver — it’s aimed at the national fuel bill and the farm economy at once.

The catch for an ordinary driver. You didn’t ask for E20, and you can’t buy pure petrol instead — the blend is at every pump. The benefit is spread across the whole country; the cost, a few percent of your mileage plus the worry about your engine, is yours alone and shows up every fill-up. That gap between who gains and who pays is exactly what a mandate does, and exactly why it stings.

Britain approves the green power, then waits for the wires

The UK has the opposite problem: plenty of approved clean energy, not enough grid to carry it. In its first two years, the Labour government approved new renewable projects at double the rate of the previous Conservatives, a Guardian data analysis found [3]. It has promised a virtually zero-carbon electricity system — 95% from zero-carbon sources — by 2030 [3].

The bottleneck sits between the permit and the plug. A wind or solar farm can be approved years before it can connect, because the wires and substations to carry its power don’t yet exist. Neso, the body that runs Britain’s grid, has been clearing “zombie” projects — schemes stuck in the connection queue without real planning permission or financing — to free up space for ones that can actually deliver on time [3].

For a household, this is why cheap approvals haven’t become cheap bills. The power is permitted but not flowing, energy prices remain high, and the 2030 target now depends less on building turbines than on building the grid to reach them [3].

The US risks missing its own EV moment

In the US, the worry is a green technology arriving just as the policy support pulls back. A new Detroit startup, Slate Auto — backed by Jeff Bezos — launched an electric pickup billed as “affordable” at a base price of $24,950, a rarity in a market where EV sticker prices keep climbing [1]. Rising costs and shifting politics have left the US industry exposed to cheaper Chinese cars [1].

At the same time, US clean-power prices are set to rise, as surging electricity demand from AI data centres collides with cuts to clean-energy subsidies [8]. The pattern rhymes with India and Britain: the technology is ready, but the cost and the timing decide who actually gets the benefit.

02 · Lesson · why it matters

Why the fix you'd choose alone can only work if nobody's allowed to opt out

Some good things fall apart the moment anyone is free to skip them — so the only way to have them is to take the choice away, which is exactly why they feel imposed.

A choice you never made shows up at the pump

An Indian driver pulls into a petrol station this week and buys fuel that is one-fifth ethanol. She didn’t pick it. There’s no pure-petrol pump to switch to. The blend is at every station, by law, and her only options are fill up or don’t drive.

She may lose 3 to 3.5% of her mileage. She may worry, rightly or not, about an older engine. And she never agreed to any of it. The government and the carmakers spent Saturday telling her the worry is overblown. But notice what they can’t tell her: that she had a say.

That missing say is the whole story. It isn’t an accident of how the policy was rolled out. It’s the point of it.

Some goods only exist if everyone’s in

Think about what India is buying. Blending ethanol into all its fuel cuts the oil it imports, keeps money at home, and pays its own farmers. Those gains are national — they exist only if the blend is nationwide.

Now imagine it were voluntary. A pump marked E20, a pump marked pure petrol, choose as you like. Almost everyone would reason the same way: my one tank barely moves the national oil bill, and I’d rather keep my full mileage. So most people pick pure petrol. The farmers don’t get paid. The oil imports don’t fall. The good the policy was after never arrives — not because people are selfish, but because for any one person, opting out is the sensible move.

This is the trap under a lot of collective goods. The benefit is shared across everyone; the cost is carried by each person individually. Do the math from a single seat and skipping always wins. Do it from the whole and skipping is a disaster. The only way to close that gap is to remove the individual choice — to make it E20 at every pump, no exit.

The feature and the grievance are the same thing

Here’s the part worth sitting with. What makes the mandate work is exactly what makes it resented. It works because you can’t opt out — that’s how the national benefit gets collected. It’s resented because you can’t opt out — that’s how it becomes something done to you.

You cannot separate the two. A version of the policy that let you keep your choice would keep your goodwill and lose its point. The grievance isn’t a flaw in the design that better messaging could fix. It’s the shadow the design casts. Every real mandate — seatbelts, vaccines, blended fuel — carries this same double face: the reason it functions is the reason it grates.

Who decided, and for whom

Ask the sharper question. Who set the 20% figure, and who does it serve? It was set above the driver — in a ministry, weighing the national fuel bill and the farm economy she can’t see from her car. It genuinely serves the country she lives in. It also serves the sugarcane growers and the ethanol producers who now have a guaranteed buyer. And it serves the state’s goal of buying less foreign oil.

All of that can be true while the driver still eats a real, small, daily cost she didn’t choose. A structure can serve its makers, serve the wider public, and still send the bill to the person with the least say — all at once. Naming that isn’t an accusation. It’s just seeing the whole shape instead of one face of it.

You are already inside a hundred of these

The Indian driver is easy to point at because her mandate is fresh and visible. But step back. The clean grid a British household is promised, the fuel standard on a car anywhere, the vaccine that only protects a population if enough people take it — every one of these is a good that only exists if the choice is taken off the table, and every one arrives feeling, to someone, like an imposition.

You are on the inside of dozens you never notice, benefiting from mandates others resent and resenting ones others benefit from. None of us gets to stand above the arrangement and grade it. We’re all somewhere inside it, holding one face of a thing that has two — which is a good reason to hold our verdict about any of them a little more loosely than the pump makes us want to.

The Pump Everyone Shares

Rehearse why a shared benefit collapses when people can opt out, and why the mandate that saves it is the same thing that makes it feel imposed.

04 · Hope · carry this

The fact that a whole country can agree to carry a small daily cost so that everyone gains is not a sign of a system pushing people around — it is proof that we can still do together the good things no one of us can do alone.
