What is the primary purpose of energy audits in buildings?
✔✔Energy audits are used to assess energy use in buildings, identify inefficiencies, and
recommend improvements to reduce energy consumption and costs.
How do combined heat and power (CHP) systems improve energy efficiency?
✔✔Combined heat and power (CHP) systems capture and utilize heat that would otherwise be
wasted during electricity generation, making them more efficient than separate systems.
What is the role of a capacitor in an electrical circuit?
✔✔A capacitor stores electrical energy temporarily and releases it when needed, helping to
smooth out voltage fluctuations and provide power during brief interruptions.
How does a geothermal heat pump work for heating and cooling buildings?
✔✔A geothermal heat pump uses the constant temperature of the ground to heat or cool a
building by transferring heat to or from the earth through a system of pipes.

, What is the environmental benefit of using hydrogen as a fuel source?
✔✔Hydrogen produces only water vapor as a byproduct when used as a fuel, making it a clean
and environmentally friendly energy source.
How does the carbon cycle relate to energy production?
✔✔The carbon cycle involves the movement of carbon through the atmosphere, biosphere, and
geosphere, and energy production contributes to carbon emissions, particularly through fossil
fuel combustion.
What is the purpose of using a heat exchanger in energy systems?
✔✔A heat exchanger transfers heat between two fluids, improving energy efficiency by reducing
the need for additional heating or cooling processes.
How does an air conditioning system cool a building?
✔✔An air conditioning system uses a refrigerant to absorb heat from inside a building and
release it outside, cooling the air by lowering its temperature.
What is the difference between conduction and convection in energy transfer?
