Infrared energy is heat radiation.
It is not visible to the human eye. Night vision goggles, or night vision cameras will often change it to a green. The brightest colors will be the hottest areas.
Living people and animals, hot vehicle engines & exhaust, and etc will all show up as bright on infrared.

Infrared light doesn't "give off" energy; in this case, it IS the energy.
Another word for infrared energy is thermal radiation.
Microwave radiation generally has greater energy than infrared radiation. Microwaves have longer wavelengths and lower frequencies compared to infrared radiation, which results in lower energy levels for infrared rays.
Infrared photography was developed to give the consumer more choices for the type of picture produced from one image. With infrared, a picture can be in color, in distorted colors, or even in black and white, all from the same image.
electromagnetic radiation in the infrared band
Another name for infrared energy is thermal radiation or heat radiation.
Infrared is heat energy and heat energy can seriously hurt because it can burn
Loss of infrared energy from the body is called thermal radiation.
The Earth and atmosphere absorb the visible and infrared energy and this warms the earth.
Gamma rays have higher energy than infrared light. Gamma rays have the highest energy among all types of electromagnetic radiation in the electromagnetic spectrum, while infrared light has lower energy and longer wavelengths than gamma rays.
Infrared waves have far less energy than ultraviolet, being much further down the spectrum.
