Step 6: Fun with algebra....

To calculate the energy consumption of a device per day, I used this equation:
a (b/1000) x c = d

a = the number of like devices (in my case, either lights or heat cable)
b = the wattage of an individual device
c = number of hours it is on per day
d = this is the answer, equal to the amount of kWh (kilowatt hours) used per day

The old setup (2 60W incandescents):
2 (60/1000) x 12 = 1.44 kWh per day
1.44 x 365 = 525.6 kWh per year

The new setup (2 20W CFL's, 2 15W heat cables)
2 (20/1000) x 12 = 0.48 kWh per day
2 (15/1000) x 18 = 0.54 kWh per day
365 (0.48 + 0.54) = 372.3 kWh per year

My energy savings:
- per day: 0.42 kWh per day
- per year: 153.3 kWh per year

I think that's pretty good.
<p>Great job. I have been trying to figure out my high electric bills, and discovered my son's two heat lamps run 24hrs a day and suck up the wattage. He has two tanks. One is 40 gallon with an adult bearded dragon. The other is 40 gallon with about 8 western fence lizards. Can you let me know what you would recommend here?</p>
<p>I just got my 20g tank along with my baby ball python. I would also like to save money on the electric bill. I did buy the zoomed snake cage kit which tells you what i have in it. Would you be able to help me out on what to use to save my electric bill before it gets to high. I know I am using 100w day time bulb and 100w night time bulb along with a medium heat pad. I know I am not using (2) light source light you but would like to simplify my electric bill asap with getting new equipment saving power.</p>
I think as owners we can reduce energy consumption quite a bit. I l also think that where we can, we should. How ever Reptiles do tend to need quite a bit of electricity in their day to day lives when kept as pets. It would be important for potential buyers to recognise this potential cost.
I agree. No reptile should have a less-than-adequate habitat, but the same result can be achieved in a number of ways. It's really worth the time it takes to investigate and plan a setup.
BEST ive heard yet on here about herps .VERY refreshing!<br>
what kinda bedding would you be able to put down over the rubber mat that would made the heat transfer suitable for the snake?<br />
None.&nbsp; I suggest using newspaper or thin cardboard.&nbsp; <br /> <br /> Reptiles can develop intestinal problems over time due to inadvertently ingesting substrate.&nbsp; Even if it says it is safe, I highly doubt it.<br />
What are the temperature ranges you read on your cage thermometers with the new bulbs?<br />
Typically the ambient temp. is in the low 80's or high 70's.&nbsp; With the open front of the cage, I don't retain too much heat.&nbsp; It's been awhile now since I did the renovation, and I like the localized heat of the heat rope.&nbsp; It's warmer in that area of the cage and provides a nice temperature gradient.<br />
Thanks for this instructable. I am saddled with AUD3000 plus elect bills annually heating 20 odd reptiles and welcome anything that could save me money. Unfortunately, my snakes are mainly arboreal and seem to like the overhead heat spot, which for most of my enclosures is a 100-150W source. Unfortunately cords or mats don't seem to cut it for these snakes except when babies. I think ceramic heat globes or radiators on pulse proportional thermostats may be more economical than incandescents. Either way, I'm saving up for a solar panel set up.
How abut a CFL/radiant heat panel combo? If they're in to basking, those radiant panels would do the trick. I'd keep it on a rheostat, though. Check online. This instructable is brought to you by eBay...
Wow! 9 feet? he's a big, pretty boa. I noticed your Kingsnake.com sticker too - I've been there on the classifieds boards to find dart frogs before, lovely little creatures. : D Good energy tips, and the coils being under the rubber surface should keep the animals from burning themselves.
