The second level of the Kardaschev scale. A Type II civilization controls all of the energy resources of its entire solar system. This means the mass of all planets is available for use as is the raw stuff of the system's primary.

Hypothetical Type II technologies include

The effects of a Type II civilization on its primary should be so great that they would be detectable from earth. The expected effects include visible oscillations in the apparent luminosity of a star (from heavy equipment traversing the visible face), massive emissions in the infrared range (heat waste from a Dyson sphere), and audible communications traffic.

The fact that we haven't detected any of these is known as the Fermi Paradox.
