My stacked washing machine/dryer that came with my apartment uses the most power, then my refrigerator, followed by lighting. Surprisingly, my TV doesn’t consume much electricity even thought it consumes power while on standby, but this is largely because I don’t watch more than an hour of TV a day. Everything else combined consumes less than the nine incandescent bulbs that I use for three hours per day. When I compare the total amount of power I consume with this method (7.5 KWH per day) to the amount of power that Austin Energy says I use, my estimate seems to be almost 3.5 KWH per short.
I figure, however, that this difference is likely due to the fact that I averaged the summer and winter usage data from Austin Energy. When I compare my monthly estimate of 225 KWH (which does not include an estimate for power consumed for air conditioning) with Austin Energy’s number of 274 KWH for January the difference is much smaller. Still, I am using 10.9 KWH of power each day, which is equivalent to leaving on 4.5 incandescent bulbs (100 watt) for 24 hours a day… every day!
My consumption of natural gas is 0.46 Ccf per day, which is equivalent to almost 1.5 MMBTUs per month. More than a million BTUs is a lot, but the firms I used to hedge for consume about 10 million times more! These firms are building product manufacturers, drug makers, and other large industrial firms. So, while I don’t directly consume a huge amount of energy, I often don’t consider how much energy I consume indirectly.
