Energy is the capacity of a physical system to perform work. Energy can be converted in various forms but not created or destroyed. Energy consumed is equal to the work done.
Energy does not have any direction. And the subtraction and the addition of the energies are not possible using vector algebra. And the energy actually derived from vector quantities of force and displacement by taking their scalar product Therefore, energy is a scalar quantity.
Hence energy is not a vector quantity.
Final Answer
No, energy is not a vector quantity.
