Yes, some quantity of energy is needed to maintain and develop resting potential of cell's membrane during the stages 1 and 2 of resting potential forming
Cell uses energy of ATP at these stages for sodium potassium pump to create difference in K and Na ion concentration inside the cell and outside. For transportation 2 ions of potassium inside and 3 sodium ions outside the cell one molecule of ATP is needed
Diffusion and the electrostatic pressure are two factors that help maintain the resting membrane potential of a typical nerve cell.
Active Transport
The resting membrane potential of a typical neuron is around -65mV
The resting membrane potential is maintained by solely by passive transport processes.

-70 mV this potential difference in a resting neuron (Vr) is called the resting membrane potential, and the membrane is said to be polarized.
The resting membrane potential of a typical neuron is around -65mV
When the membrane potential becomes more negative it is being hyperpolarized. Remember the resting membrane potential is already at a negative state (~70mV). So if you are making a comparison of a membrane potential that is hyperpolarized in comparison to a resting membrane potential, the resting membrane potential is said to be more depolarized.When the membrane potential becomes more positive it is called depolarization.

-70 mV this potential difference in a resting neuron (Vr) is called the resting membrane potential, and the membrane is said to be polarized.
Neurons have a resting membrane potential of approximately -70mV. Muscle cells have a resting membrane potential of approximately -90mV.

Potential hyperpolarization are more negative to the resting membrane potential because of voltage. This is taught in biology.
