Nuclear fusion.

Heat energy and light energy when the current passed through them.
no, a freezer is a source of energy and it makes coldness.
Mainly light and other electromagnetic wave.
Light and heat
There are many different forms of kinetic energy, but there are three that are most common. Linear Kinetic Energy (straight line motion) Rotational Kinetic Energy (Like a spinning top) Spring Kinetic Energy (A spring oscillating back and forth)
A light bulb gives out light energy and heat energy as forms of energy. The light energy is emitted as visible light, while the heat energy is generated as a byproduct of the bulb's operation.
Stars give out light energy, that is they are luminous. Thus we see them for the same reason we see a lighted torch bulb.

Firstly, planets are way way smaller than the stars! That's because you can see stars in the night but never planets. Also stars produce nuclear energy in their core so they give thermal ( heat ) energy. Also stars have more gravity than planets.
