2) A.O. Smith 1 HP Motor EE - Full Rate (B2841, B2841V1) - INYOPools.com - This one is listed as "energy efficient" and has a listed 1hp with a 1.65 SF for a total of 1.65hp. This one has an amp draw of 7.8 - 7.4/14 amp. It costs $200, so it's about $40 more than the 1st one I listed.

My question is...would the lesser amount of amp draw on the 2nd one be enough to see a difference on my electrical bill over the life of the motor? I don't mind spending more if it pays for itself by saving me money on my bill.
