I've had a kidney transplant in the year 2005 and my mother donated the kidney. my creatinine is 1.7 right now. is it safe for me to consume alcohol ?

Well yes: But your renal function is compromised. Ask your nephrologist.

Yes, in moderation: Alcohol does not specifically harm kidney function although it does have a gentle diuretic effect. If there is no other specific health reason to avoid alcohol use (such as liver disease or other medication that should not be used with alcohol), then an occasional drink is reasonable. Of course, this must be done in a socially responsible manner (do not drink + drive, etc).
