Home Island/Natural resources

Each Home Island contains varying amounts of natural resources. The amount of resources mined by Excavators is modified by the resources size modifier on the Map Selection screen while the amount which can be extracted per tile is further affected by the ore mining yield modifier on the Game Difficulty screen. On the other hand, the amount of Crude Oil and Water is modified by Extra Starting Material modifier on the Game Difficulty screen. Any modifier cannot be changed once the island has been founded.

It should be noted that most of the above natural resources are non-renewable. But there are alternative ways to get unlimited resources.

• Dirt can be created by dumping Compost onto the ground or mixing Compost and Gravel.
• Sand can be created from Quartz by processing it in a Crusher twice.
  • Manufactured Sand, made from Rock via Gravel, can substitute for sand in Concrete Slab and Filter Media production
• Wood is infinite, since Trees can be planted with Tree Planters.
• All other resources can be imported infinitely from Outposts or by Contracts, and some of them can be indefinitely created/collected in more ways:
  • Water can be indefinitely collected by 3 different ways:
    • Rain replenishes the Natural Groundwater Resource lode (which can be pumped with a Groundwater Pump).
    • Rain can also be collected directly with the use of a Rainwater Harvester.
    • Seawater can be pumped limitlessly from the sea with a Seawater Pump(Tall) (This method requires the post processing of the Seawater into the Water.)
  • Coal can be created from Wood with a Coal Maker.
• Crude Oil consumption can potentially be avoided in the late game using the Biodiesel technology for Diesel and Naphtha Reforming for Naphtha.
