This mod adds tons of new ores and machines. First you want to get batteries, they are the main power source in the mod. There are 2 types at the start, clay and Lead acidic. The good thing about Lead is that it is rechargeable, but more expensive. Clay batteries are cheap, but have a one times use. Lead batteries are crafted using Sulfuric water, which can be found in a sulfur valley, and lead plates. Lead plates can be made using clay batteries or sulfuric water in an electric forge. Below is the recipe for the electric forge and for copper gears.

To do that get a steam generator, then place 1 water bucket and 2 coal inside with your battery to recharge it. Recipes below:
