what exactly is an energy efficient pool pump? browsing google links, for example,
this is a sample list of pricing for a pump:

1 1/2 H.P. Motor $119 Heavy Duty $139 Energy Efficient $169

as you can see, the energy efficient model is $50 more than the regular model

I also looked at this page
http://www.electricmotorwarehouse.com/pool_pumps.htm

where it appears they have a "Capacitor Start", meaning (?) it reduces the LRA or
power surge at startup?

if anyone has replaced a standard Sta-Rite inground pump with one of these, please
tell, what did you find and was there a difference in power consumption and did all
your filters & pool cleaners continue to run normal?

there appears to be also incentive programs for installing a two-speed pool pump?
anyone done this? how did the program work?
can you purchase a qualifying pump over the web and install it yourself and still
qualify?
