The article is the written exchange of two of the magazine’s editors in a competition to track their energy use. I had downloaded my electric bill about a month earlier, and I decided to join in the comparison a year late (and without the technological gadget). Without the special software, I would only be able to estimate my daily use. That’s still good enough for me to begin to understand how much power my wife and I use compared to other households.

First, I checked out PPL’s website, which lets consumers access special tools to understand their electricity use. I downloaded the account history and looked at the kilowatts used. Big increases in the winter months and valleys in the summer. Our rented half-double has no insulation (we’ve bugged the landlord about it to no avail – and without much opportunity to look for other options). That means the heating unit uses plenty of electricity trying to keep the old house warm during the cold winters. We topped out at 693 kilowatts in February 2008 – before we began dialing the thermostat way down during the day. Our best full month was July 2007 when we used 336 kilowatts.

An easy spreadsheet formula gave me the number of days in each billing period. From there, it was easy to track the average kilowatts per day. The Outside article (if you didn’t follow the link) says the average American household uses 30.25 kWh per day. The most we used was 23.1 kilowatts in February 2008, and our best month was 10.5 kilowatts in July 2007. The two competing editors fell between about 8 and 18 kilowatts. I have some work to stay in their league. My median was 14.86 kWh, and the mean was 15.28 kWh. There aren’t big fluctuations in our energy use except for a few key months when it really spikes.

Average daily electricity use

I wondered what the trend was from year to year. I took a few minutes to reconfigure the chart to map out the monthly use over the course of 2007, 2008, and 2009 – and I checked the mean for each of the 12 months. So far in 2009, we’ve been below the monthly average every month except for January.

I’ve actually followed the average pretty closely for most of this year. August heat and air conditioners have driven up our electricity in the past – that’s something we haven’t done this year with a cooler summer. Look like the windows are staying open this year, and I’m looking for ideas on how to winterize.

But global warming is how everyone thinks of climate change so Friedman writes about a series of interviews where his subjects talk about noticing warmer weather. Western ranchers talk about less snow remaining on mountain tops. Another person speaks about the number of record highs and lows set across the country each week. That left me wondering whether I could find any change in weather in my area simply by looking at record highs and lows and when they were set.

I checked the National Weather Service’s repository of record highs and lows for the Scranton/Wilkes-Barre area – my current home. I used the tables from 1955 to present because they’re pulled from a consistent place (the airport) rather than the general area. I typed the date, record high (“maximum high”) and corresponding year, and record low (“minimum low”) and corresponding year into an Excel spreadsheet. It’s unfortunate that the records only cover 54 years, but they’re taken from a consistent area, which was more important to me than whether they covered 100 years worth of temperatures.

Because I wasn’t counting leap day, I had 365 days. The time period covered 54 years. Simple math says that if there are 365 record highs and 365 record lows, I should be able to expect about 7 record highs and 7 record lows each year.

If this covered two years – 1955 and 1956 – I’d expect half of the highs to be from 1955 and the other half to be from 1956. If it covered five years – 1955 to 1959, I’d expect 20 percent of the highs (73) to come from each year. Because I have 54 years, I expected 1.85 percent of the highs to have occurred in any one year. In a 365-day year, that’s 6.75 days. There were 365 lows as well – one for each day of the year. Odds say that another 6.75 lows – rounded to 7 – would set records each year.

I realize that some years just happen to be warmer or cooler than others, and so I wanted a way to lump years together. I decided to do it by decade. There were five years in the 1950s, nine years in the 2000s (the chart doesn’t cover 2009 temperatures), and 10 years for the 1960s, 1970s, 1980s, and 1990s. So odds say that I should have 33 or 34 records from the 1950s, 60 or 61 records from the 200s and 67 or 68 records for the other decades. If my numbers were around there, we’d be setting roughly equal numbers of record highs and record lows each year – and you wouldn’t be able to track the weather getting warmer or colder.

I didn’t get those results.

As you can see, there were a lot more record high temperatures set more recently than record lows. In the 1990s and the 2000s, there were 77.8 percent more record highs set than record lows set. We were still setting record low temperatures, but we were setting new high temperatures much more often. While the 1990s represented 18.5 percent of the years in the study, 26 percent of the high temperatures occurred in that decade. The 2000s represented 16.7 percent of the years, and 21.9 percent of the high temperatures. The 1950s are 9.3 percent of the years in the study, and 5.5 percent of the high temperatures. That same decade has 15.3 percent of the record lows for the period.

We’re setting both new highs and new lows in each decade. But there highs are coming more frequently most recently. But how drastic is the change? It’s difficult to see because the 1950s and 2000s don’t have the same number of years included as the other decades. To have a better view of the trend, I divided the 54 years into nine groups of six years each: 1955-1960, 1961-1966, 1967-1972, 1973-1978, 1979-1984, 1985-1990, 1991-1996, 1997-2002, 2003-2008.

Odds should say that you should have roughly equal number of record highs and record lows set in each time period – just more than 40.5 each. (1.85 percent of the highs in each of the six years is 11.1 percent of the records, and 11.1 percent of the 365 days in a year is 40.5.) The final numbers didn’t match the odds. Remember, the number of records for both highs and lows should be right around 40.

I’ve been really surprised to see this result. I’ll take some time to look into individual months to see if any part of the year is more affected than another. But it turns out to have been pretty easy to chart the fact that’s it’s getting warmer in Northeastern Pennsylvania. We’re setting many more record highs than record lows.

Quick disclaimer. My six months of numbers are a little dated – the last quarter of 2008 and first quarter of 2009.

The e-newsletter, web page, and a blog received the majority of views during each month so I just looked at those sources. I left the e-newsletter numbers out as well because I wanted to understand whether the e-newsletter really increased the number of web page and blog views. So I focused on those two numbers. And I looked at the six-day period from when the e-newsletter was sent. Over the course of the typical 30-day month, those six days are 20 percent.

A copy of the e-newsletter was kept on the website and many articles were posted on the site as well. While each open and click could be listed as a page view, I only measured hits on the index page. The newsletter offered the chance to go to my organization’s “home page” a link to the index page – and a number of people did so. In the six days after an e-mail (20 percent of a month) we always had more than 20 percent of our monthly hits – as high as 34 percent in the final month that I tracked. The main web page generated 29.5 percent of its hits in the 20 percent of the month after an e-newsletter.

This trend was even more obvious in the blog hits. We launched the blog on WordPress.com in September, added a link to our web page late in that month, and began to promote the blog in the e-newsletter in October. The concept of visiting the blog was new to stakeholders throughout this period, and the monthly e-mail provided a great reminder and driver to the blog.

During half of the months studied, the blog received more than half of its page views in the 6 days immediately after the e-mail. While this isn’t an 80/20 split, overall the blog received 49.7 percent of its traffic in the 20 percent of the time following an monthly e-mail.

Content was likely one of the main reasons the blog fared better than the web page in the days after the e-mail. But the takeaway is the same. When planning communications, include something regular to provide your audience with a gentle reminder that you’re there. E-mail is deleted too easily and too regularly – especially when you lean too heavily on it. But e-mail is low-cost and unobtrusive enough that it can give your readers a push to get more information about you.

Between these two inconveniences (they’re minor – this isn’t a major metro region), you’ll a dozen drivers jockeying for position. You’ll have traffic heading on and off the expressway. There’s always a truck from a distributor pulling out to block traffic. You’re likely to hit a parent stop in traffic lane to let a child out for school.

The rest of the drive is fairly empty. All of the congestion is in a really small area. That small patch of roadway determines whether I’m early, on-time, or late. The majority of the trip has no impact on the final results.

I was thinking about that as I drove to work yesterday. I knew that I’d spend the day writing and coding a monthly e-newsletter.

Research might suggest that e-mail is losing effectiveness. It’s too easy to delete (if it isn’t marked spam). The addresses in your list eventually go out of date. The information is scanned and discarded compared to interactive websites, social networks, and online communities.

(Disclaimer – we don’t spam, everyone has prior relationship with us, we process unsubscribes and opt-outs, etc.)

I’ve found our monthly e-mail is the largest driver of traffic to each of these other channels. The website hits go up. The blog views skyrocket. The clicks on Twitter and Facebook pop. It’s the reminder to our stakeholders to check in – using whichever program or format you’d like – to the institution where I work.

In other words, the three-day window of e-mail opens has a huge effect on the month traffic. What have you found?

Stats are all over the place about how many messages a person receives in a normal day. Lots of studies have talked about this saturation.

How many people are receiving the messages? How many of the 37 million-plus words written on WordPress or its platforms (as of my writing this) are read?

That’s what this blog is (now – updated 11:10 p.m.) about.

In a time of user-generated content, can all of the stuff being created actually be meaningfully consumed? How – without spamming everyone who’s a friend, connection, or follower – can I get my message distributed. And am I sending the best message to them?
