👉 The term "thermopower" is used to describe the ability of a device or system to convert heat energy into electrical power. Thermopower refers to the efficiency with which a device converts heat energy into electrical energy, and it can be measured in terms of both power (which is the amount of electrical energy produced by the device) and efficiency (the percentage of thermal energy used). Thermopower is often used in industries such as HVAC systems, refrigeration, and other forms of heating
