The light is electromagnetic energy; so is the heat radiation. Heat transported through conduction or convection is no longer electromagnetic energy.
Electromagnetic waves ARE radiation.
Your question is very hard to understand, but the process that releases electromagnetic radiation in the sun is called fusion.
We are warm enough to emit infrared rays.

Many things give off electromagnetic radiation. Cell phones, the body, x-rays, and supposedly ghosts and spirits. EMF detectors (or electro-magnetic-field detector) are also supposed to pick up electromagnetic radiation given off by anything it's pointed at.
It gives off a range of electromagnetic radiation of shorter wavelengths.
Well a warm object gives off infrared electromagnetic radiation, which can be absorbed in another object, heating it up.

A grill that cooks meat gives off electromagnetic radiation, both visible and infra-red. Some of the cooking is also done by convection.
