Because Gliese 581 is only 1% as bright as the Sun, it exudes little warmth, and its habitable zone lies much closer. At this distance, planets get locked into strong gravitational pulls that tend to slow their rotation.
Roughly the same goes for Gliese 581d, which has a stronger presence in the habitable zone on its far side, but may not be hot enough for liquid water - opinion is not 'completely settled' on this matter.
Although we currently know very little about Gliese 581g, a couple of its features strongly indicate that this planet might harbor the existence of organisms.

Studies show that watching your friends and family in stressful situations can loosely synchronize your heart rates, a strong manifestation of human bonds.
The dams create strong water flows which move turbine blades that turn the rotor of an electric generator. When the coils of wire on the rotor sweep past the generator’s stationary coil, electricity is produced.
