Why is demand for air conditioning increasing?

Demand for air conditioning is bound to increase. One reason is climate change: as the world warms, more people will be exposed to heat waves, and those who already live in hot climates will experience more intense ones. But that''s not the only — or even the biggest — driver of demand. The biggest driver is rising incomes.

Skin Effect and Factors Affecting Skin Effect in Power Lines

What is Skin Effect? When an alternating current "AC" flows through a conductor, it is distributed non-uniformly throughout the conductor and tends to stay more near the surface of the conductor. This phenomenon is called Skin Effect which is applicable to AC only as the flow of current is uniform in the X-section of conductors in case of DC.
