Answer: The molecule 
is expected to have a dipole moment of zero.
Explanation:
The product of magnitude of the charge calculated in electrostatic units is called dipole moment.
Formula for dipole moment is as follows.
Dipole moment = Charge (in esu) 
distance (in cm)
Non-polar molecules have zero dipole moment.
For example, is a non-polar molecule so its dipole moment is zero.
is a polar molecule so it will have dipole moment.
is a polar molecule so it will have dipole moment.
has nitrogen atom as more electronegative than hydrogen atom. So, net dipole moment will be in the direction of nitrogen atom.
Thus, we can conclude that the molecule is expected to have a dipole moment of zero.
It also depends on what we use to make the energy in the power plants. Many use uranium which is non renewable. A better alternative would be wind or solar as it is always around. Hope this helps.
