I've got a fridge set up in my garage loaded full of delicious home brew, all ready to drink. To save on power, I'd like to only turn it on when I need it, say once a week or once a fortnight.
Could I cause any damage from the large fluctuations in temperature? Right now it's likely to swing between 4°C 30°C (~40-86°F).

Letting the beer get warm will shorten its shelf life as the heat speeds up staling reactions. Doesn't really matter that its cycling from hot to cold or not. Its a cumulative time at warm temps that short the freshness over time. Its not the best practice.
Depends on what you mean by "damage", but that is how the labs quickly simulate how a beer will go through staling reactions over time.
Could you put a temperature controller on the fridge and hold it at cellar temperature (~55F)? That would keep the beer at a stable temperature in a good range for aging, but still be warm enough to cut down on electricity costs.
