An object that is a good radiator of electromagnetic waves is also a good source of energy (heat,light ...)
Radiant energy is the energy of electromagnetic waves. The quantity of radiant energy may be calculated by integrating radiant flux (or power) with respect to time and, like all forms of energy, its SI unit is the joule. The term is used particularly when radiation is emitted by a source into the surrounding environment. Radiant energy may be visible or invisible to the human eye.

The sun. Energy in the form of electromagnetic radiation excites electrons in the solar cell and is transformed into electrical energy.

Accelerated electric charge is the source of electromagnetic waves.
The main source of energy in our solar system is the Sun, which emits significant quantites of electromagnetic radiation due to nuclear fusion processes which mostly occur in its core.
Any energy source that is renewable does not increase carbon dioxide (CO2) levels in the environment. Examples of renewable energy are solar, wind, hydro, tidal and wave, geothermal and biofuel.
