Heating and Cooling Trends for the past 113 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 113 years.
Well that's interesting but how does this effect the people of New
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 113 years
Here is the annual HDD's for the past 113 years along with the trend line.
The 11 year moving average shows we have 315 fewer HDD's than our ancestors of over 100 years ago.
Cooling Degree Days for the past 114 years
Now the annual Cooling Degree Days (CDD)
The 11 moving average shows that we have 65 fewer CDD's than our ancestors of 114 years ago.
It's interesting to note that the climate changes to New Hampshire over the past 100 years have resulted in what today would be a decrease in energy use for heating and cooling.
