Power

Most Buildings require electricity, or power, to run. Power is generated in generators and has to be supplied to your buildings via a power grid consisting of Power Lines and Power Poles. Power is measured in megawatts (MW).

Power grid
A power grid is a network of power-generating and power-consuming buildings connected through power lines and poles. A graph of total power production versus consumption can be viewed by activating any power pole or generator on that grid. If consumption ever exceeds production, the grid will overload and shut off, requiring manual reactivation at one of these. Before reactivating, it is recommended and sometimes necessary to either attach more power generators to the grid or remove power-consuming buildings, otherwise, the grid will simply overload again as soon as it's reactivated.

Power generators
Power generators convert fuels into power. Each type of generator building has its own set of fuel item types and power output. Fuel consumption depends on power consumption. At 50%, fuel will last twice as long as at 100% consumption.

Biomass Burner
Consumes various forms of organic matter to produce 20MW of power for each generator built. Up to 2 biomass burners are attached to the HUB. Most harvested fuel items can be crafted into Biomass to increase their energy, and biomass can be further refined to Biofuel.

Notes:
 * Biomass burners must be fed manually and can therefore not run indefinitely without player interaction
 * Biofuel has a lot of energy for early game but requires two crafting processes to acquire

Coal Generator
Coal generators consume Coal to produce 75MW of power per generator.

Notes:
 * Coal has less energy per item and per stack than Biofuel but is much easier to acquire in bulk
 * Coal generators can be supplied via belts to allow them to run indefinitely

Fuel Generator
Fuel generators consume Fuel to provide 150MW of power per generator.

Geo Thermal Generator


A Geo Thermal Generator can be built on a Geyser node to provide 200MW of power. It does not require any resource input to function. Geo Thermal Generators do not scale with power consumption and always produce 100% of power, which means that other generators only have to produce the difference between your total power consumption and what Geo Thermal Generators produce. This means, if the total power consumption is less than the total power generated by Geo Thermal Generators alone, no other generators will run and fuel resources for those generators will be conserved.

Nuclear Reactor
Nuclear Reactor consumes Nuclear Fuel Rods and generates 2500MW of power. It also produces Nuclear Waste that emits dangerous radiation and can not be disposed of by normal means.

Update 3

 * Coal Generators and Nuclear Power Plants now require Water, which is supplied by Water Extractors and carried through Pipelines. There is one input on each building.
 * Coal Plants now produce 75 MW to balance the water change.

Clock speed
Overclocked/underclocked production buildings consume polynomially more/less power, while production speed increases/decreases linearly. Overclocking power generators increase their power output at a loss. Overclocking one to 200%, for example, will result in 170% of its original power output. Fuel consumption is still proportional to power consumption.
