Percentages are fraction of energy source with respect to total.

Unique Observation

Overall, there is a significant increase observed in Hydro Power generation between 2013 and 2018 in Canada, whereas, energy sources such as Biomass and solar experienced a downward trend. However, over this same period, sources such as gas, nuclear and wind also experienced significant growth.
