EU - Energy Unit is the measure of energy used by IC. It is most similar to the SI derived unit Joule. EUs are 'produced' by generators, stored by mobile units like an RE Battery or by stationary units like a batbox, transmitted along cables, and 'consumed' by ICs various machines.

EU stored in items or devices does not leak over time.

EU is not related to Redstone current, but multiple machines can be affected by redstone currents, and a Detector Cable produces redstone current if there is any EU passing through it. Some machines allow a lever to be mounted directly on its block.

Raw EU values are used to measure capacity of energy storage items or blocks.

EU/t[edit]

EU/t means Energy unit per tick. It is a derived unit of energy over time, a rate of EU consumption or production, similar to the SI derived unit Watt.

The sum of all EU/t in a wire can be measured with an EC-Meter by clicking twice; once to begin measurement, and again to finish and display the measurement. It can also be observed by the rate of change in EU capacity displayed by storage devices like the batbox.

Minecraft normally operates at about 20 ticks per second, unless you are experiencing client or server lag.

EU-Packet[edit]

EU-Packet is abbreviated as EUP, which is also used interchangeably with EU Power: the maximum size EU packet a device or wire can handle.

EU-Packets are the transmission containers of EUs in Industrial Craft 2. Each tick, the EU sent or received by each machine is done so by an individual EU-Packet.

EU-Packets come in different sizes ranging from 1 EU to 2048 EU, unlike IC1 you may not change EU output of storage devices.

Emitters[edit]

  • Generators and storage devices emit EU-packets as big as their output.
  • Storage Units always emit packets the size of their "out" value.
  • Transformers behave like Storage Units. They are able to upgrade four packets into one of a higher tier or downgrade a single packet into four of a lower tier.

Cables[edit]

Cables are limited by the size of EU-Packets that may travel through, NOT the number of packets, NOR the total EU/t contained by these packets. If an EU Packet too large for a cable to handle tries to pass through, the cable will be destroyed.

For example, an unlimited amount of 32 EU-Packets can pass through a Copper cable per tick, but not a single 128 EU-Packet.

Energy loss of a cable is applied to every EU-packet, not the total EU/t passing through. Ex. Using a gold cable, sending 4 32 EU-Packets in a cable (by using 4 batboxs) results in 4 times the energy loss of sending one 128 EU-Packet (by using a MFE Unit). See the Voltage Efficiency section for more information.
