Question

Explain what is meant by degraded energy:

• A. Reduced energy after conversion
• B. Unuasble energy due to lack of facilities
• C. When energy in one form is converted to another, part of the energy has to be expelled into the environment. This is called degraded energy
• D. None of these

Answer 1

The correct option is C When energy in one form is converted to another, part of the energy has to be expelled into the environment. This is called degraded energy

Degraded energy is thermal energy that is released into the surrounding environment after any process. Once released into the surroundings, this heat energy is completely useless for energy production and is considered 'dead' or 'degraded energy'.
