Heat, kinetics and steam

Besides EU there are two forms of energy that do not travel through cables: they only pass between two adjacent blocks, face to face.

Heat generators output it through their front (the orange square):

Generator	Source
Solid Heat Generator	furnace fuel, 20 hU/t (leaves Ashes)
Fluid Heat Generator	biogas and liquid fuels
Electric Heat Generator	10 EU → 10 hU per Coil (up to 10)
Radioisotope Heat Generator	radioisotope pellets, 2 to 64 hU/t
Liquid Heat Exchanger	hot coolant from the fluid reactor (or lava)

Heat is used by the Blast Furnace (steel), the Fermenter (biogas), the Stirling Generator (2 hU = 1 EU) and the Steam Boiler.

The shaft of a KU generator goes against the front of a Kinetic Generator, which gives 1 EU per 4 KU.

Wind Kinetic Generator: with a rotor (Wood Rotor, Iron Rotor, Steel Rotor or Carbon Rotor). Wind grows with height (nothing below Y 64) and with rain or thunder; the rotor disc must be clear. The Windmeter measures wind.
Water Kinetic Generator: in a river or the ocean, with the rotor underwater.
Manual Kinetic Generator: 400 KU per click.
Electric Kinetic Generator: 100 KU/t per Electric Motor.
Steam Kinetic Generator: with a Steam Turbine inside, turns steam into KU.

Rotors wear out with use.

The Steam Boiler turns water into steam with heat. In its GUI you choose the pressure (0 to 300 bar): more pressure needs more heat per mB and a higher temperature. From 221 bar it makes superheated steam, which gives twice the KU.
The Steam Kinetic Generator turns steam into KU and condenses it into distilled water, which goes back to the boiler. Regular water calcifies it.
The Condenser and the Solar Distiller make more distilled water.

Careful: heat the boiler does not use overheats it, and above 500 °C it explodes. If steam has nowhere to go, it leaks and hurts.

Plants → Plantball → Macerator → Bio Chaff → Fluid/Solid Canning Machine with water → biomass → Fermenter with heat → biogas (and Fertilizer). Biogas burns in the Semifluid Generator or the Fluid Heat Generator, which also accept liquid fuels from other mods.
