Not really. Check here for a nice simple explanation. You can test this at home if you like. Put a set of steel rims on your bike and go for a ride. Then put on a set of aluminum rims. The steel rims take much more energy to get moving and keep moving than the aluminum rims.

Edit: I just saw MechbGon's post on winter tires. This is a much easier demonstration to accomplish then a steel vs aluminum wheel comparison. I have a front studded tire and will only use it if I absolutely have to. The damned thing is difficult to get rolling and significantly impacts my commuting times.
