As they store a lot more energy, weight for weight.
Lipids have around twice the energy density of carbohydrates, so they are a more efficient means of storage (i.e. only half the mass is needed to store an equivalent amount of energy).

The internal energy reserve is starch in plantsSTARCH : actually these starch are excess carbohydrates which are stored in the plant bodyBut in case of animals we have a similar type of storing energy called glycogen but not as same as in the plantsGLYCOGEN : they are stored forms of energy in animals
It is a carbohydrate. Glycogen is a polysaccaharide stored in animals and starch is a polysaccaharaide stored in plants. Carbohydrates give you the energy you need to do life processes. Cellulose is a structural carb. It is the most abundant biological material on Earth.
Different reactions have different metabolites which may act as energy storing molecules. For instance, in glycolysis, fructose-1,6-bisphosphate and phosphoenolpyruvate represent just two of the main energy storing molecules.
They are storing chemical energy, indicating cell identity, and serving as raw material for synthesizing other molecules.
Fat and glycogen have different chemical properties. Fat contains more energy for mass than sugars. For birds, who need to be very light to remain aerodynamic, storing a vast majority of the energy as fat is much more efficient.
Most autotophs that live in environments that have no light rely on chemosynthesis to synthesize energy storing molecules (mostly as carbohydrates). Many chemosynthesizers live near hyrdrotermal vents and use the hydrogensulfide emitted by the vents to "fuel" the chemical processes of chemosynthesis.
