Is it possible to produce Energy while producing Cold as a byproduct?

HEAT is energy trapped in atoms and molecules, making them vibrate. Everything we humans do results in heat. Our roads and buildings absorb heat during the day and release it at night. Power plants, cars, planes. Electronic devices such as computers, TVs, cell phones, etc. Even our refrigerators and air conditioners produce heat as a byproduct. Only photo-cells and wind turbines can produce energy while being comparatively neutral in heat production. So here's a brain teaser. Is it possible to design a device that does the opposite, that not produces energy,but does it by absorbing heat during the process, resulting in cooling the air and objects around them? If so, think of the benefits. Power plants, cars, etc. that have the side benefit of cooling the air around them. If used widely, a device like this could potentially balance out or even reverse the global warming effect that our technology, our very presence has on this planet. I know that this idea sounds very counter-intuitive. Activity, biological or mechanical, normally produces heat, according to the laws of thermodynamics. As we all know, heat is everywhere on this planet, and nearly impossible to get rid of. So what if we could put it to use? Reverse the process that created the thermal energy in the first place by converting thermal energy into an energy resource such as electricity. It sounds very science fiction, but heat is a real thing, compared with cold. Cold is just nothing, the absence of heat. Since excess heat is the most plentiful (and currently unwanted) thing on the planet, why not figure out how to get rid of it by converting it into something useful? The person who figures out how to do this, and patents it could get rich. All you physicists out there, think about it!
