Electricity

I keep hearing anecdotal tales from people concerned about their energy usage. Often more from a financial impact than concern about environmental impact, sure, but I've never figured out why the numbers I hear quoted sound so much more severe than what I notice actually paying.

So, here's a summary of my electricity bills for the last year, for reference, this is a 1 bedroom apartment on the ground floor:

Date	KWH Read	KWH Usage	# Days	Avg. Usage.	Charges
05/08/2008	99813	502.00	29	17.31	59.79
04/09/2008	99311	368.00	30	12.27	44.11
03/10/2008	98943	377.00	32	11.78	45.36
02/07/2008	98566	287.00	29	9.9	34.78
01/09/2008	98279	364.00	33	11.03	44.21
12/07/2007	97915	436.00	31	14.06	53.76
11/06/2007	97479	606.00	32	18.94	86.53
10/05/2007	96873	626.00	29	21.59	81.56
09/06/2007	96247	618.00	30	20.6	77.46
08/07/2007	95629	602.00	29	20.76	76.11
07/09/2007	95027	558.00	32	17.44	67.63
06/07/2007	94469	468.00	30	15.6	57.55
05/08/2007	94001	401.00	31	12.94	47.98
TOTAL:	-	6213.00	397	15.64	776.83

So in 13 months, I spent nearly 800 dollars on electricity. I've heard people say that last summer near hear, they spent the same in two summer months.

I'll be the first to admit that I'm not the most conscious about my energy usage. My fridge is old-ish, I run the A/C whenever I'm home almost year-round, I have computers that are powered up 24/7.

So I'm curious, am I "green" even with my perceived usage pattern? Is it a rash of "this is how much it feels like I'm paying" bias in estimation? Tall tales? Exaggeration?

"ZOMG, you wasteful monster, I pay so much less than you in a similar climate/economy"?
