Electricity

Electricity is a new useable form of energy introduced in version 1.4.

Appearance
Electricity isn't an item that can be carried. The only time it's visible is when it's being conducted along copper wire or through a conductive block. At those times, it's shown as small, cyan squares moving along the wire.

Generation
There are two sources and one storage method for electricity. A steam generator or solar panel will each create electricity. A flywheel will store electricity that comes to it and supply it to connected crafting surfaces that need it.

Each of the above has as part of its block graphic a series of eight small "indicators" on the left side. For the steam generator or flywheel, it shows how much total power the unit can supply before it's drained. For a solar panel, it shows how much power it can generate based on conditions.

Use
Electricity will only flow between connected crafting surfaces. This is possible by having them adjacent (horizontally or vertically) or by a continuous series of copper wire between them. Note that crafting surfaces will not conduct current to other crafting surfaces (except for the flywheel, which is actually a special type of generator).

The following crafting surfaces require electricity to function:
 * Electric Stove (improves on the campfire)
 * Electric Kiln (improves on the kiln)
 * Electric Furnace (improves on the furnace)
 * Electric Metalwork Bench (improves on the metalwork bench)
 * Flywheel (stores electricity)

Added in version 1.5:
 * Electric Elevator Motor (drives elevator shafts)

Added in version 1.6:
 * Electric Press (improves on the press)
 * Electric Sluice (grinds gravel for a random ore)
 * Refinery (crafts advanced items, uses more electricity)

These crafting surfaces craft most items craftable at their non-electric counterparts with the same required items, but instead of using fuel directly, they must have a supply of electricity.
