What role do gas turbines play in meeting global energy demands, especially concerning renewable energy?

• They are the sole source of energy, replacing renewables entirely.

• They provide a dependable and consistent baseline, complementing renewables when they are insufficient.

• They are only used when renewable energy sources are abundant.

• They primarily serve as a backup for nuclear power plants.

What is the initial step in the operation of a gas turbine?

• Fuel is injected into the combustion system.

• Hot gas moves past the turbine blades.

• Air is drawn into the compressor section.

• A magnetic field of electrons is created.

What type of energy is created when fuel is burned with compressed air in the combustor of a gas turbine?

• Mechanical energy

• Electrical energy

• Chemical energy

• Kinetic energy

How is chemical energy converted into mechanical energy within a gas turbine?

• By directly generating electricity from the fuel.

• By heating water to produce steam.

• By igniting the fuel and air mixture to create hot gas that spins turbine blades.

• By compressing air to extremely high pressures.

How is electrical energy produced in a gas turbine system?

• By directly burning fuel to create sparks.

• By the mechanical energy of a rotating drive shaft spinning a magnet within metal coils.

• By the compression of air molecules.

• By the chemical reaction between fuel and air.
