In some if not all hotels you can find ways they are becoming 'green'.
Surprisingly in one hotel they had low energy bulbs in the bathroom, replacing the five bulb light unit with lower power equivliants.
Most hotels now have a policy about bed linens and towels.
The hotel policies ask you to indicate if you want the linens cleaned or not, a change from the previous policy of replacing everything, everyday.
With so many people staying in hotels these steps can only be a positive thing, both for the hotels financially, and for the environment.
