We get most of our "quick" energy from carbohydrates but also energy from proteins and fats.
Lipids contain the greatest amount of chemical energy compared to carbohydrates and proteins. Per gram, lipids contain 9 calories, whereas carbohydrates and proteins contain 4 calories per gram.
Carbohydrates provide the most readily available energy as they are efficiently broken down into glucose, which is the body's primary source of energy. Unlike lipids, nucleic acids, and proteins, carbohydrates can be quickly metabolized to produce immediate energy.
Lipids store more energy per gram than carbohydrates or proteins.
Lipids provide the most amount of energy per gram compared to carbohydrates and proteins. They contain twice as many calories per gram (9 kcal/g) as carbohydrates and proteins (4 kcal/g).
Fats (lipids) contain the most energy per gram compared to proteins and carbohydrates. While proteins and carbohydrates provide 4 calories per gram, fats provide 9 calories per gram. So, gram for gram, fats contain more than twice the energy of proteins and carbohydrates.

proteins, fats, carbohydrates, and water
when an organism uses most of it's carbohydrates, it can get energy from these lipids

Lipids provide the most amount of energy per gram compared to carbohydrates and proteins. They contain twice as many calories per gram (9 kcal/g) as carbohydrates and proteins (4 kcal/g).
Fats (lipids) contain the most energy per gram compared to proteins and carbohydrates. While proteins and carbohydrates provide 4 calories per gram, fats provide 9 calories per gram. So, gram for gram, fats contain more than twice the energy of proteins and carbohydrates.

When we consume food, we get macronutrtients. These include carbohydrates, fats and proteins, the amount depneds on what food/foods are consumed. In terms of energy, fats provide 9 kcal/g, carbs 4 kcal/g and proteins 7 kcal/g. Therefore the most energy dense nutrient is fat and so on.
