The map above shows which US states used the most electrical energy for both light and power in 1921. Essentially the map is showing a combination of which states had the most people combined with commercial and industrial activities.
The map only shows, 49 ‘states,’ since in 1921 both Alaska an Hawaii had yet to become states in their own right. However, Washington DC is listed (number 35) to bring the total to 49. The state with the lowest electricity consumption in 1921 was New Mexico.
The Top 10 states in terms of electricity used were:
- New York
- Washington (state)
The reason why Montana makes the list, despite having virtually no people, has to do with large amount of mining in the state, which takes a huge amount of electricity to carry out.
Looking at more recent data from 2014, the list looks quite different. Vermont is now the state with the lowest total electricity consumption.
The Top 10 states in 2014 were (rank in 1921):
- Texas (19)
- California (3)
- Florida (40)
- Ohio (5)
- New York (1)
- Pennsylvania (2)
- Illinois (4)
- Georgia (22)
- North Carolina (15)
- Virginia (26)
The rise in the number of southern states is likely due to a combination of factors, most notably the invention of air conditioning and the rise of low cost southern manufacturing.
