What does the term "energy recovery" refer to?

The term "energy recovery" specifically refers to the process of capturing and reusing waste heat or energy. This concept is crucial in improving energy efficiency and reducing overall energy consumption. In many systems, such as industrial processes or power plants, a significant amount of energy is lost as waste heat during operation. By employing energy recovery techniques, this waste heat can be collected and repurposed for heating buildings, generating electricity, or even powering industrial processes.

For example, in power generation, waste heat from steam turbines can be used to heat water, which can then be used in district heating systems or even pre-heating feedwater to increase the efficiency of the boiler system. This not only contributes to energy savings but also minimizes the environmental impact by making better use of available resources.

Understanding this definition helps contextualize energy recovery in the broader discussion of energy management and sustainability, emphasizing the importance of maximizing the utility of all forms of energy produced during industrial and residential activities.
