US 2023 energy use

Make big measurements feel comparable.
A visual summary of Brian Potter's Construction Physics energy cheat sheet, extended with common distance heuristics as an ambient reasoning surface: exact labels stay on the page, shared scales recur, and the same object appears as unit, route, activity, infrastructure, sector, and national system.

22.59 quadsmostly chemical fuels; grid electrical storage is only 0.002 quadsCore data summary
What the metrics say in one page.
Hydrocarbons are absurdly compact.
A gallon of gas is 33.7 kWh, a barrel of oil is 1,700 kWh, a tanker truck is 313,410 kWh, and an LNG carrier is 1,125 GWh. The built world exploits this density constantly.
Electricity is efficient but storage-poor.
Motors, transformers, transmission lines, batteries, hydro dams, and heat pumps sit high on the efficiency ladder. But US grid electrical storage is only 0.002 quads against 22.59 quads of total storage.
Heat dominates the demand side.
Residential heating plus hot water plus dryers is 64.8% of household energy. Industrial process heat alone is 7.576 quads. The hard problem is thermal civilization, not just light bulbs.
Transport is liquid fuel civilization.
US transportation uses 27.99 quads. Gasoline is 15.91 quads, diesel is 6.71 quads, and road vehicles account for 78% of transport energy.
Distance heuristics
From the Shanghai 内环 to a full planet loop.
The same kilometer object is shown three ways at once: named route, log-scale position, and ratio against the Shanghai Inner Ring plus the Earth equator. That keeps the ladder of abstraction visible instead of hiding the useful comparisons in hover text.

The hidden machine
Decarbonization is not just new power plants; it is replacing a continent-sized logistics stack.
These are not plotted as bars because their units differ. Tufte move: when magnitudes do not share a denominator, show them as labeled facts instead of forcing a fake chart.

the continent-scale delivery network electrification must route around or replace

Standing on one foot
Hydrocarbons win on density, movement, and storage; electricity wins on efficient conversion. Decarbonization means rebuilding the bridges between those strengths.
The strategic mistake is treating energy as one number. The successful players silently track five denominators at once: quantity, rate, efficiency, storage duration, and sector fit.
