energy
Let an agent handle energy in both senses, the physical quantity and the energy supply, with units, sources, costs and emissions stated clearly.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent handle energy in both senses, the physical quantity and the energy supply, with units, sources, costs and emissions stated clearly.
Energy as a quantity and as a resource: the capacity to do work, measured in joules, and the fuels, electricity and heat that societies produce, trade and consume.
What it is for: Powering homes, transport and industry; understanding energy systems and their impacts.
It can be measure and meter it; produce it, from sources such as solar, wind, fossil fuels or nuclear; buy, sell and store it; reduce its use and emissions.
Distinguishing features
Physical quantity and societal resource
Conserved, but degraded in use
Sources differ in emissions and cost
Energy and power (rate) differ
What it looks like
Meters, power lines, fuel, solar panels and bills; energy itself is not visible.
Physical character
SI unit: joule J - 1 kWh = 3.6 MJ
heat of combustion of natural gas: about 50-55 MJ/kg
How it is recognised
kWh on bills, MJ on fuel specifications
Energy labels on appliances
Sources such as green hydrogen or distributed solar

- Should sources and carriers be separate entries?
- How should green claims be verified?
