Cool news

I made two major changes to my electrical consumption during the same week, about 6 weeks ago. I changed most of my light bulbs to compact fluorescents (the remaining light fixtures get used either rarely or briefly). And Tall Son finally rendered operational the recycled central air conditioning unit that he salvaged for me last summer.

This time last year I was cooling by using two window a/c units and keeping my spare bedroom and office doors closed, so I was only cooling a part of my house.

To add to the equation, two weeks ago I had removed the tree in front of my house that provided shade during the afternoons, so I'm sure that the a/c now has to work even harder to keep me cool.

I’ve spent one very comfortable month: I keep the temp at about 75, even at night (I sleep poorly if I’m hot).

So today I got the electric bill, and I fully expected that upon opening that bill I’d have to turn the a/c up to 80 and start living in the dark.


The bill is for $74.69. For a full month. In Florida.

The recycled a/c is a Trane, but it’s 10 years old, so I wasn’t sure it would be all that efficient. I suppose it is.

My electric company offers interesting statistics on the bill: the KWH total and daily average and the same info from the same month one year earlier. Last summer, same month, with partial-home a/c and incandescent bulbs, I used a daily average KWH of 29. This summer, it’s 25.

I won’t really know the impact of the bulbs alone until a/c season is over and I can compare KWH consumption during the heating months to last year’s consumption.

But for!
