Its important to know the source of energy in convection currents because it is what drives the movement of the plates, formation of plate boundaries, and hot spots.
Explanation:
The convection currents are currents that occur in the mantle layer. The prime reason as to why they appear is the difference of heat and pressure between the upper and lower mantle. The energy itself exist because of the core of the Earth, as it is very hot and it has extremely high pressure, so it heavily influences the mantle layer above it.
The importance of understanding the energy source of convection currents is seen in that through it we can understand why we have plate boundaries at some places and not in others, why are spreading zones occurring, and why hot spots occur in the middle of the plates, far away from the boundaries. By understanding these things, we can understand the plate tectonics theory, thus the motion of the plates on Earth's surface.
