Well, that is getting better!
Ok, so I was watching an old episode of Top Gear (the good Brittish version) and they were driving electric cars. Jeremy said the Nissan Leaf used just 0.1kW per mile. So to go 100 miles it would use roughly 10kW of electricity. This got me to thinking...how does R2-D2 compare to an electric car? So I busted out some maths...
When I hooked R2 up to a Kill-a-Watt, he drew 822W while folding on the CPU (at 4.7GHz) and both GPUs (at 725MHz). That equates to 0.822kW. Therefore, for the same amount of electric it takes to run a Leaf 100 miles, my computer can run for 12.17 hours. Now, the really sad part. This made me decide to figure out what it costs me to run the beast per month (and frankly, I was kinda scared).
So, you figure in a normal 30 day month, there are 720 hours. So, at 0.822kWh, R2 uses 591.84kWh. I pulled up my last electric bill and found that the overall cost for our electric (for both generation and delivery) is $0.074526 per kWh. So, 591.84 * 0.074526 = $44.11 per month.
Now, if I compare that to our overall usage, it gets stupid! Last billing cycle was 34 days and we used a total of 1,698kWh of electricity. R2 alone used 670.752kWh (cost: 670.752 * 0.074526 = $49.99!!). So, to get the percentage of overall usage that R2 used I would do ((670.752 / 1698) * 100) = 39.5%. So basically, I could drop my electric bill by almost 40% just by shutting down R2!!
Yeah, I knew folding was an expensive hobby when it comes to the addiction of building / upgrading hardware, but I’ve never actually calculated the cost in electric before!! HOLY CRAP!!
Now does this mean I’m going to stop folding? No. However, I have a goal of making it to inside the top 500 worldwide (I’m at 694 right now), but once I hit that, I might have to slow down. Also, I have a few rigs at home that don’t put up many points (2 of them put up less than 1k PPD), so I think I’m going to slap the Kill-a-Watt on those, figure up the cost and see if it would help me significantly to shut them down, but other than that, I’m going to continue full steam ahead!
There was no real purpose to this post, othere than I figured all this up and need to tell someone. I can't tell my wife, if I did, she'd kill me and sell off R2!! Anyway, there it is, have a good one, team!!Edited by WonderMutt - 2/6/13 at 9:44am
