Delhi's grid fix and Europe's electric trucks: the economics of electrification tighten

The claim ran on 29 September in Hannah Ritchie's By the Numbers newsletter, which worked through Eyre's numbers. Total final energy demand drops from 416 to 247 exajoules. Electricity demand rises from 110 to 189 EJ. The world uses less energy overall once it stops burning fuels directly.

Delhi shows what grid repair is worth

The same week, IEEE Spectrum published a first-person feature on how Delhi cut electricity losses from 50% to 5%. A distribution utility fixing itself rather than adding capacity is rare. The article, dated 29 September, is written by a Delhi resident who describes the winter of 2002, when power cuts were routine and streetlights were out. The piece is a feature, not a peer-reviewed study, so the 50-to-5 figure is the magazine's account of the utility's performance.

Grid investment is not just about new cables. A 28 September analysis from Transport & Environment, republished by CleanTechnica, found that in six of nine major EU truck markets, electric trucks are already the cheapest option on a total cost of ownership basis. The six markets cover 46% of all new heavy trucks sold in the EU. Five-year savings reach €100,000 in the Netherlands, €85,000 in Germany and €69,000 in Denmark, with payback in two years. Buy a Chinese truck instead and the Dutch saving rises to €128,000.

The report credits scale, lower truck prices driven by EU CO2 targets, national purchase subsidies and lower road tolls. It argues the gap widens if Europe faces another energy crisis. T&E wants member states to keep the 2030 target of a 43% cut in truck CO2, implement CO2-based tolling under the Eurovignette Directive and use RED III e-credits for depot charging. Without those, the arithmetic changes.

Charging, fleets and the missing infrastructure

Distance from the grid is the binding constraint elsewhere. CleanTechnica's 29 September op-ed on the 14th Philippine Electric Vehicle Summit, opening in October, notes that the country's roadmap requires 311,700 electric vehicles and 7,300 charging stations by 2028, under the Electric Vehicle Industry Development Act. With two years to go, the article says the charging target is the weakest link. Government agencies and commercial cargo operators must make EVs at least 5% of their fleets. The summit floor, the author writes, will show whether local builders can displace diesel jeepneys at viable margins.

Manufacturers keep moving. Volkswagen said on 29 September that its new ID. Tiguan will premiere in early October and reach markets in early 2027, replacing the ID.4 and ID.5 while the combustion Tiguan stays on sale. The company has produced more than 8.3 million Tiguans, and the ID.4 and ID.5 have delivered more than 950,000 units since 2021.

Tesla is working on a different problem. Electrek reported on 29 September that the USPTO granted US 12,746,987 B1, an "Electric Fan Car" patent using four ducted fans in the rear diffuser to generate downforce independent of vehicle speed. The drawings show a Model S, which Tesla stopped building in April. The patent was filed in January 2024 and traces to a provisional from 17 January 2023. The fans draw power from the main high-voltage pack.

None of this settles the investment question. Electrification reduces energy demand, but it moves spending to wires, chargers and depots, where the returns depend on policy that can change. That is the gap between the 40% saving and the €100,000 truck.
