Heating and Cooling Trends for the past 112 years
From the monthly data analysis page we saw that the cooler months contributed the most to the annual average temperature increase over the past 112 years. Well that's interesting but how does this effect the people of New Hampshire. Our heating and cooling bills are definitely the the first things that come to mind, so let's look at the way that our energy suppliers determine how much energy we use by looking at Heating Degree Days (HDD) and Cooling Degree Days (CDD). Along with monthly temperatures the data from The National Oceanic and Atmospheric Administration (NOAA) also includes columns with HDD and (CDD).
Heating Degree Days for the past 112 years
Here is the annual HDD's for the past 112 years along with the trend line.
The trend line calculation shows that your ancestors of 112 years ago would have had an average of 482 more HDD's than we do now.
Cooling Degree Days for the past 112 years
Now the Cooling Degree Days (CDD)
Summary
The trend line calculation shows that we have 41.43 more CDD's than our ancestors of 112 years ago. What we see here is that the heating trend has decreased 10 times for every cooling increase.
