The new Sydney CBD and Southeast tram runs without overhead wires along George Street in the core. Though it does have overhead wires outside the CBD. Trams in Sevilla and Bordeaux are wireless, if memory serves me correctly; however, I don’t recall if that’s only in certain sections. On the plus side the TTC has finally managed to figure out the pantograph. So, you know, baby steps.
Cannot speak to the Bordeaux trams, have not been there - but: From my recollection, and unless it has subsequently changed, Sevilla trams are only battery between stations, at least in the downtown area. There are catenary wires at the stations, which provide power to the rapid recharge batteries. The new Sydney CBD trams have pickup shoes under car body, with a segmented centre rail which is energized section by section as the tram passes over.
