Lågkvalitetsenergi

Lågkvalitetsenergi refers to energy that is widely dispersed and at a low temperature, making it difficult to extract and utilize for useful work. This concept is rooted in the second law of thermodynamics, which states that in any energy transfer or transformation, some energy is lost as heat, increasing entropy. Lågkvalitetsenergi is essentially the waste heat or residual thermal energy that remains after a process has occurred.

Examples of lågkvalitetsenergi include the heat dissipated from engines, industrial processes, or even the ambient heat in the environment. While this energy is present, its low concentration and temperature mean that significant effort and specialized technology would be required to convert it into a form that can perform mechanical work or be used for other high-grade applications. Recovering and utilizing lågkvalitetsenergi is a key area of research in thermodynamics and energy efficiency, as it represents a potential source of untapped energy that could reduce reliance on primary energy sources. Technologies such as heat exchangers and thermoelectric generators are explored for their ability to capture and convert low-grade heat into more usable forms.
