To reduce electricity cost, I always undervolt/underclock my GPU cards. Most card manufacturers "optimize"' their default/stock setting with gaming performance in mind. You see lots of gaming benchmark been published. For BOINC projects, for me at least, I do concern about PPD (points per day) per watt as a measure of power efficiency. Granted that output will be lower but not much. If I cut my GPU PPD output by 10%, I do cut my power consumption way more than 10% and that reduces electricity cost especially when you run the project 24/7/365. Less heat generated and less need for AC turning on all the time. I did some study on GPU crunching efficiency a while ago. Just google "GPU crunching efficiency" and it will lead you to the study that I've done.
BTW, I live in California where the electricity cost is one of the highest in US and expected to go up in the future, so power efficiency matters to me a lot. I know this is very situational as it depends on individual. Just my one cent.
SO FAR I haven't had to do that, but I may in the future if the stock market keeps going down like it has been. I'm pretty much well diversified but a down day is still not a money making day!! I live at the beach in NC just North of the SC line so get alot of breezes on most days which keeps the a/c units from running full blast. I also have a room in the garage for my pc's and only cool it to 82F which helps as well. Except in the hot summer time I can keep the door open and just let the outside air move thru keeping the a/c use to a minimum.
I have a program that can be used to calculate how many watts a GPU or CPU uses to produces credits which can show the best performing projects (for credits or gridcoins). The program can be run from this webpage

I occasionally underclock my GPUs when they heat up and on occasion stop hyper threads on CPUs that have inadequate cooling.
Converted a system to liquid cooling but didn't pay attention to the tubing. My problems reported here

However, I would like to offer some tools that could be used to help with energy efficiency.
While there are cheap wattmeters available, the one I built below is pretty good and also cheap.

picture above is too big to show here but it is "wiring diagram" for "100A Digital Panel Watt meter" typicall $12 on ebay
Assembled looks like this (pic too big like the other)

and if you scroll all they way down at this post

you can read a description of how to use the program
