Infrared radiation is not visible ,it's not visible because it is an electromagnetic radiation with wavelenghts higher than the visible spectrum. read more

So my answer to “where infrared energy is most commonly found” would be everywhere that the temperature is above −273.15°C (Celsius scale) or −459.67°F (Fahrenheit scale) or 0 K (Kelvin scale). read more

Infrared radiation is popularly known as "heat radiation", but light and electromagnetic waves of any frequency will heat surfaces that absorb them. Infrared light from the Sun accounts for 49% of the heating of Earth, with the rest being caused by visible light that is absorbed then re-radiated at longer wavelengths. read more

Infrared sensing. One of the most useful applications of the IR spectrum is in sensing and detection. All objects on Earth emit IR radiation, or heat, which can be detected by electronic sensors, such as those used in night-vision goggles and infrared cameras. read more
