Why can energy prices affect almost everything else?
Energy is both a household purchase and an input embedded across production and transport.
The intuitive answer
Only electricity bills and petrol prices should change.
In 30 seconds
Energy powers transport, heating, machinery and many industrial processes. A price shock therefore raises direct household bills and the cost of producing and moving other goods. The final effect depends on energy intensity, contracts, substitution and how wages and expectations respond.

A widely used input transmits its price through production networks; second-round wage, price and expectation responses can broaden and prolong the initial shock.

The deeper explanation
The short answer is the start, not the whole story.
Energy powers transport, heating, machinery and many industrial processes. A price shock therefore raises direct household bills and the cost of producing and moving other goods. The final effect depends on energy intensity, contracts, substitution and how wages and expectations respond.
Common overstatements
Firms may absorb costs or switch inputs instead of raising prices, but that response can reduce profits, investment or output rather than eliminate the shock.
Where the answer stops
The effect is stronger in energy-intensive economies and during persistent shocks; regulation, taxes and subsidies can change who bears the cost.
Concepts that unlock it
Input-output network
The web of industries buying inputs from and selling outputs to one another.
Energy intensity
The amount of energy used to produce a unit of output.
Pass-through
The share and timing of an input-cost change reflected in later prices.
Second-round effect
A later wage or price response that extends an initial shock beyond its direct impact.
What if?
What if an economy used half as much energy per unit of output?

Evidence and limits
What supports this answer?
Energy shocks can affect inflation directly through household energy and indirectly through production costs, with size and timing varying by sector and episode.
