The major factor for differentiating this energy is the source of energy. Renewable energy sources are well-established and consist of naturally replenishing resources like sunlight and wind. Ambient energy, on the other hand, encompasses various forms of low-density energy present in the environment and requires specialized technologies to capture and convert it into usable energy.

Esthella Ekong answers this well. I want to add a few examples of each

Renewable*: naturally occurring self-replenishing sources of energy: solar, wind, hydro, geothermal, bio-based (biomass)

Ambient*: derived from a surrounding environment (could be natural or created environments): examples residual thermal energy in the air (ambient air temperature - applied in PCM TES systems), waste heat from a machine or from industrial process (e.g., the exhaust heat of dilution of sulfuric acid with water or waste heat from boiler operations, etc.,)

Thank you Allan Takudzwa Muzhanje and Esthella Ekong for your answers. Is it possible to sub-divide the ambient energy as "ambient energy from renewable energy sources" and "ambient energy from non-renewable energy sources"?

Ambient energy is nature’s energy that never gets harnessed by people. Society uses this energy without creating infrastructure to capture and transform it, but ambient energy is often useful. Energy sciences focuses on energy that people harness from nature

Renewable energy is energy derived from natural sources that are replenished at a higher rate than they are consumed. Sunlight and wind, for example, are such sources that are constantly being replenished. Renewable energy sources are plentiful and all around us.

Both ambient and renewable energy are good for the Earth, but they come from different places and are used differently.

Ambient energy comes from small natural things around us, like heat or moving objects, and is often used for little tasks like running small devices.

Renewable energy comes from big, never-ending natural sources like the sun, wind, and water, and is usually used to give power to homes or even whole towns.

La energía Ambiental es la REAL existente en ese espacio y las Energías Renovables, porque aún son más costosas para las Economías actuales.
