What is Waste Heat?

Waste heat is produced by machines that do work and in other processes that use energy. It has a lower utility than the original energy source. Instead of being wasted by release into the environment, sometimes waste heat can be utilized by another process, or a portion of heat that would otherwise be wasted can be reused in the same process if make-up heat is added to the system.

Questions?

Where does waste heat come from?

Waste heat is produced by machines that do work and other processes that need energy, or by processes that output a lot of energy. That energy is called waste heat.

How is waste heat turned into energy?

although its not finalized, waste heat can be turned into energy by using thermoelectrics. Its a material that turns heat into usable electric energy.

Why is waste heat capture important?

capturing waste heat is an important piece of not only boosting energy efficiency initiatives, but ultimately of reducing greenhouse gas emissions. Improving energy efficiency without addressing waste heat is an effort that is inherently handicapped.
