Energy and work

Factorio simulates many aspects of real physics and the quite correct use of energy is one important aspect.

Energy and work are directly dependent.

Work

Work is "stored energy". If you divide the work into parts and release the parts in some time you have energy.

Work is measured in Joules, which is one Watt over the time of one second. See Units#Work.

Types of work

Work is available (or storable) as

• Fuel.
• Capacity in the Basic accumulators.
• Hot liquids. You can create them in the Boiler store serious amount in the Storage tank.

Energy / Power

Energy is the "flow of work". The amount of flow is power.

Energy is measured in Watts, nearly every device in Factorio needs energy to work. Energy is produced by Electricity/Generators, Boiler- or other burner- (or motor-driven) devices (like the car or train).

See Units#Power.

Types of energy

Fuel-based (Boiler, Burner)

Fuel contains a certain amount of energy. The fuel is burned and produces energy (which is converted into movement or heat) and Pollution is emitted.

There are some devices, which can use fuel directly.

Electricity

Electricity is produced by Generators. The distribution is made over an Electric network, and it is used by Electricity/Consumers.

That's the single parts! The whole process is also explained as Power Production.

Electricity is the only way to transport energy over long distances. Electricity itself doesn't pollute, the pollution comes either from burning fuel or consuming electricity.
