Energy

Energy is not stored – it is produced and consumed at every moment. Each planet has its own energy balance: the mines and the Blast furnace consume energy, while power plants and solar cells supply it.

Energy sources

• Fusion plant: the basic supply of every planet. It needs no fuel and delivers more energy with every level.
• Solar cells: in SpaceInvasion 2, solar cells are defense units. You build them in the Weapons factory, and they use no building fields. Each cell turns sunlight into 10 to 60 energy – the closer the planet is to its sun, the more. Because they are units stationed on the planet, they can be destroyed in an attack.
• Thermosolar plant: delivers much more energy than fusion but constantly burns Spice. It is only worth it if you have Spice to spare – the Tech tree shows its requirements.

Energy technology increases your energy production by 1 % per level – on all planets at once. It is also a requirement for many buildings, defenses and research projects.

Surplus energy

Energy your buildings do not use is not lost: it charges the particle storage of the Particle cannon and Particle shield and the Teleporter. Under Economy you decide in which order the surplus is distributed. If you need more surplus, you can also throttle individual mines there.
