Air is an insulator. But sometimes it get possible when there is humidity.

Well, there is electricity and there is electrical energy.
Electricity can indeed be transferred through the air - but standard temperature and pressure air has very high resistance to the flow of electric current. This is a good thing and makes walking under high voltage power lines more convenient.
Voltage is electrical pressure somewhat analogous to water pressure. Once a sufficiently high voltage (approximately some 30,000 volts across an air gap of 1cm) has started electric current flowing through air, things get out of hand in a hurry as the air itself changes composition by ionizing.
Ionized air has a very low resistance so electricity can flow in quantity; once an electric arc gets started it can be hard to extinguish.
This is the spark you see when you unplug an appliance - as even the household 110 volts is enough to get the current flowing through air if the 'gap' starts small enough.
Nature uses millions of volts for lightning and therefore has much more fun. Same electricity, largely the same physics.
Generally, passing energy through a non-conductor like air is best done by converting the electrical energy to something that the air does not impede. To do this electricity is generally first converted into either of two forms of energy: photons (light) and magnetic fields.
Converting electric energy to light and sending that light through the air to be re-converted to electricity is done by devices as simple as your TV remote control. Batteries power the infrared LED and at the TV end photo-receptors convert received infrared photons into an electric current.
Converting electric energy to magnetic fields and recovering that energy is the technology behind 'wireless chargers' now coming to your local handheld device.
