Housing Units Source of Heat in Connecticut

How does Connecticut heat up their homes during the cold seasons? There are numerous ways to provide heat for a home. This visualization shows the different types of heat sources and how many housing units use them for each Connecticut town. You can see trends in the data when looking at the maps. Towns with urban environments tend to use utility gas and kerosene as a source of heat. Rural and suburban towns tend to use liquefied petroleum gas or wood as heating sources. Surprising data I found is that some homes use solar energy for heat. There is not a lot of homes that use solar energy, but maybe the number will increase in the future as we adapt to more renewable energy. The data source is from the American Community Survey 5-year estimate from 2011 to 2015. This data visualization is for the 2015 year.
