What uses the most/least energy?

[MitchT]

Electric fan oven on 175 deg C for 50 minutes or 900W microwave on full power for 5 minutes?

Fan oven uses more.

The fan-oven would use more energy just to get to the set temperature I'd say.

A 900W microwave will use more than 900W though! Wikipedia says average 64% efficient, so actual power usage would be ~1.4kW...
