Electrical Energy can be used to power things, light lightbulbs and even kill you.
This is an example of natural electrical energy.
You can transfer electrical energy by conduction. This is an example of electrical energy energy being transferred by conduction through the copper wire.
Brass and gold are also great conductors.
Electrical energy can also cause heat, like in this picture the contact from the lightning has caused a fire. Many of the forest fires are caused by lightning.
Without electrical energy we could still be using candles for light.
