Steam Generator

The Steam Generator is the first electricity producer available. It produces electricity when it's loaded with water and fuel, and then turned on (it's turned on by default when first constructed). The amount of electricity produced gradually increases until the temperature reaches 200 degrees C. This is when it produces the maximum 12 EU/sec.

It needs Fuel which is consumed over time. It will accept any type of fuel. However, it does not produce any by products of spent fuel, such as charcoal and ash that you would get from other wood burning structures. The best fuel is a Firelog. It's a good idea to have several of these kept in the generator as often as possible so any fridge on the grid won't lose power and allow perishable items to rot.

Tips

 * Keep it well stocked with Firelogs and Bottle With Pure Water to ensure it doesn't shut down when you're logged off. It holds up to 100 Bottle With Pure Water.
 * Ensure the total electricity consumed by other structures doesn't exceed a combined 12 EU/sec. If the amount of electricity exceeds this, another generator should be built.
 * As with any electricity producer, it's a good idea to also build some Power Storage units. These will help reduce the burden on the generator, saving fuel and water.
