A basic generator has looped wire (coil) that is rotated in between a magnetic field (present because of an existing magnet) and as a result, current is induced in the wire.
The rotation actually can wear down the wire and thus, many generators choose to move the magnet instead of the wire.

Wood & Biomass
Renewable (from Sun)
Renewable (not derived from Sun)
Tidal Power (due to the oceans grav. pull with moon.)
Geothermal Energy (tectonic plate friction; geysers)
Denmark produces 20% of its electricity from wind power.
