All electrically-powered machines now consistently indicate their tier (supply voltage) in their names. As this implies that they are electrically powered, the furnaces no longer have "Electric" in their names. The fuel-fired equivalents of electric machines, which exist for alloy furnace and furnace, now say "Fuel-Fired" to distinguish them. (The fuel-fired alloy furnace used to say "Coal", which was inaccurate because it uses any fuel. The fuel-fired furnace, from the default mod, used to just be called "Furnace", which is ambiguous.) Electric power generators now consistently indicate their tier and have the word "Generator" in their names. This makes their purpose much clearer, and makes obvious craft guide searches produce useful results. The fuel-fired generators, previously just (ambiguously) called "Generator", are now explicitly "Fuel-Fired".

-- A geothermal EU generator
|
|
-- Using hot lava and water this device can create energy from steam
|
|
-- The machine is only producing LV EUs and can thus not drive more advanced equipment
|
|
-- The output is a little more than the coal burning generator (max 300EUs)
