Almost definitely the alternator belt slack or slipping then..... you should be able to move it no more than about half an inch downwards in the longest run AFAIK, but it depends on a lot on the car specs.

Take a piece of kitchen towel and with the engine off wipe the face(s) of the belt that touch the drive wheels. If it comes out black and oily you have contamination.

Note: I have seen this a lot in the past where people have been very liberal with WD40 under the bonnet during the wet months of the year.
