After almost reaching cruise altitude of 25;000 FT MSL; we had a Hydraulic Low Level light illuminate for the Green System. We read the checklist and conferred with Dispatch and considered the safest course of action would be to continue to [destination]. During cruise flight we then lost the entire Green Hydraulic System. We then ran that checklist and talked with Dispatch again and once again considered the safest course of action would be to continue.With the loss of the Green Hydraulic system; we lost landing gear operation; flap operation; outboard flaps and nose wheel steering. With these considerations we decided the best course of action was to land on a longer runway. Once we checked on with Approach; we declared an emergency and continued to run the checklist for gear extension by free fall. The landing gear came down without incident and we safely landed and taxied to the gate without incident.Note should be taken that the aircraft was written up (by myself) in the logbook for 'possible hydraulic leak under the left nacelle' the previous evening and was signed off by a mechanic the day of the event without finding a leak. The mechanic said he believed that there wasn't a leak and that it must have been residual fluid that dripped down from a previous fill.
EMB-120 Captain reported losing Green Hydraulic System. After consulting Dispatch the decision was made to continue to destination.
