Hello W/m2 is not the unit of energy. Students get confused usually as we use the symbol E for the energy radiated per unit area per second. So it is not only the energy. It is the energy emitted in one second. So J/s which equals to W. Per unit area needs /m2

So W/m2 is not the unit for energy. Only J ie joule is the unit of energy.
