The energy required is 30 watts second.
In order to accomplish work and to produce heat and light, energy must be transferred to a body or to a physical system. Energy is the quantitative attribute that does this. Energy is a preserved resource; according to the rule of conservation of energy, energy can only be transformed from one form to another and cannot be created or eliminated.
The voltage of a battery is 12 V and;
The charge is 2.5C.
Now, energy can be defined as the product of voltage and charge.
Therefore,
E = V × C
E = 12 × 2.5
E = 30 watt second
Hence, the energy needed by the 12 V battery to move 2.5 C through the electrical circuit is 30 watts second.
