India’s energy story is being written in public and at speed: a 20% ethanol blend reached roughly five years ahead of the original target, a non-fossil capacity milestone hit in 2025, and a pump price whose composition most people have never seen itemised.

This is the index to everything we publish on it — fuel, blending, renewables, rail and the consumer costs of electrification. Every timeline separates what has been achieved and measured from what is a target, a projection or a claimed figure, because in energy policy the distance between those is where the argument lives.

The timelines

How to read this cluster

The E20 timeline is the entry point: it is the most consequential fuel change Indian motorists have experienced in a generation, and the one with the most active public disagreement about real-world effects. The fuel price dynamics timeline is the one to read if you have ever wondered why the pump price moves the way it does. Renewable energy transition covers the grid side, and is careful about the distinction between installed capacity and actual generation — a distinction that is routinely collapsed in coverage.

What we are watching

The E20 standard’s effect on older vehicles, whether any blending target beyond 20% is formally adopted, and whether renewable generation catches up with renewable capacity.
