== Units ==
Stormworks doesn't use real-life units of electricity. The system is also simplified, so voltage and amperes are not simulated. The unit of energy used by the game doesn't line up with any real-life unit of measurement, so most people call it "SWatt" (or Stormworks Watt). Generators measure their output in this unit, and batteries use SWatt seconds.

For example: A small battery has a capacity of 1600. This means that at 1 SWatt of generator output, it would take 1600 seconds to fully charge it from 0% to 100%.
