Unit for energy

The unit for the consumed energy is described with "C". Does this mean calories? Then why is it not abbreviated to "kcal" or expressed in Joules "J"?

Calories with the capital letter C are so called large calories and means kcal.

https://en.wikipedia.org/wiki/Calorie

"The large calorie, food calorie, or kilocalorie (Cal, Calorie or kcal), most widely used in nutrition,[3] is the amount of heat needed to cause the same increase in one kilogram of water.[4] Thus, 1 kilocalorie (kcal) = 1000 calories (cal). By convention in food science, the large calorie is commonly called Calorie (with a capital C by some authors to distinguish from the smaller unit)."
