The Electric Furnace is an improved and more costly version of the Iron Furnace.
The benefits of this device compared to the Iron Furnace are that the Electric Furnace is 12.5% faster and, as the name indicates, uses electricity. By running on electricity instead of burning items, it is able to shut off immediately upon finishing (and thus avoid wasting energy). You can best take advantage of this by having some form of energy storage between the Electro Furnace and the generator(s).
The Electric Furnace uses approximately 390 EU per operation. When connected to a Generator, one piece of (char)coal will provide 10 operations. An Iron Furnace, in comparison, uses 400 EUs per operation (Coal has an EU yield of 4000 in a Generator and provides 10 operations in an Iron Furnace) and it doesn't stop when there is nothing left to smelt. Additionally, an Electric Furnace can be powered by alternative sources such as Solar Panels.
Simply add something to smelt in the top slot and supply the Electric Furnace with EU.
- The lower slot is used to provide power from a RE Battery or other energy storage item if a direct Cable connection is not available.

†Other Wood Items = Any block with its material set to "Wood" (includes blocks added by other mods if material defined properly). Includes all other items that can be burned in a regular Furnace, see
Smelting for a complete list.
‡Assuming the smelting of 2 items simultaneously, divide by 2 if you are only smelting one item. For values < 2 keep in mind that you will actually have 2 partially finished units.
††Lava buckets are worth 10% of their value (2000) inside Iron Furnaces and Generators.
The Electric Furnace can accept overclocker upgrades, meaning that it can potentially smelt items faster than its advanced counterpart, the Induction_Furnace. While an Electric Furnace with a large number of overclockers can smelt items much faster (about 20 items per second max) without drawing energy when inactive, it can only process one stack at time, making it horrendously energy-inefficient in comparison.
