Structures

Most structures become available at different Ascension Levels while some can only be created because of an animal's special ability or from scientific discovery. Structures can be removed by demolition; requiring varying amounts of explosives. Many upgrades require Energy which can be produced by power plants, energy crystals, and spaceships. Most structures require your animals in order to function. Some power plants and foundries can create pollution.

Dwellings
Dwellings allow you to increase the population of the planet

Power
Power Plants (PP) help produce Energy for use on your planets. Power plants can create pollution. * Nuclear Energy: Pachydus or Science Discovery

** Solar Energy: Cocodrills or Science Discovery

*** Wind and Geothermal Energy: Science Discovery

Farms
Farms produce redballs to feed your animals, with the rate measured in number of seconds it takes to generate items (PPS). The Plant Nursery and Greenhouse help increase the planet's regeneration. * Hydroponics: Cocodrills or Science Discovery

Mines and Wells
Mines and wells help extract resources from the planet, with the rate measured in number of seconds it takes to extract items (PPS).

Foundries
Foundry structures create resources, with the rate measured in number of seconds it takes to create items (PPS). All structures under Foundries have a capacity of 1 animal.

Ascensions
Ascension structures help increase your ascension points. Some structures can convert resources into ascension with the rate measured in number of seconds it takes to complete conversion (PPS). Other structures increase the amount of ascension produced at the end of each planetary cycle. * Jewelry Shops: Kalypsians or Science Discovery

** Restaurants: Cosmoporks or Science Discovery

Sciences
Some science structures help increase your Science points by converting resources into science with the rate measured in number of seconds it takes to complete conversion (PPS). Others convert science into resources. You can build extra Spaceships or upgrade them; notice that they don't take energy, they generate it! In addition, the Synthesis reactor is found here for generating oil and fertilizer. Finally, air filters reduce pollution by absorbing pollution points. * Air Filters: Pandarians or Science Discovery

Scorers
Scorers help with your final score. They do not need occupants and they can't be upgraded. They don't require energy and they don't create pollution. They just give you a higher score. (And they look pretty cool.)

Warfare
Did someone talk about you behind your back? Are they moving in on your planet? Don't put up with it! It's time to protect yourself and fight back! Warfare structures don't need occupants and can't be upgraded. The Planetary Shield adds 50 shield points to the planet; increasing your planets hitpoints by 50.
