Which of the following is NOT a renewable source of electricity?

• Hydropower.
• Natural gas.
• Wind energy.
• Solar energy.

What type of power plant generates electricity using water?

• Wind power plant.
• Hydroelectric plant.
• Thermal power plant.
• Nuclear power plant.

If electricity is generated from renewable sources, what does that mean?

• It can be used indefinitely without depletion.
• It is always cheaper than non-renewable sources.
• It is generated only during the day.
• It cannot be stored.

What is the first step in the journey of electricity before it reaches our homes?

• It is stored in batteries.
• It is generated in power plants.
• It is sent to substations.
• It is used in factories.

Which type of power plant generates electricity using water?

• Wind power plant.
• Hydroelectric plant.
• Nuclear power plant.
• Thermal power plant.

How does electricity travel from power plants to homes?

• Through underground tunnels.
• By being stored in batteries.
• Through high voltage power lines.
• By being carried by trucks.

Which of the following statements accurately describes the role of substations in electricity transmission?

• They convert electricity into different energy forms.
• They store electricity for future use.
• They reduce the voltage to a safe level for homes.
• They generate electricity from renewable sources.

If a transformer increases the voltage, what does it do to the electricity?

• Makes it safer to use.
• Converts it to a different energy form.
• Pushes it through power lines more effectively.
• Stores it for later use.

What is one reason why high voltage is used in power lines?

• To reduce the risk of electrical fires.
• To allow electricity to travel longer distances.
• To increase the amount of electricity generated.
• To make electricity cheaper.

What is the purpose of high voltage power lines?

• To store electricity for later use.
• To reduce electricity consumption.
• To carry electricity over long distances.
• To connect homes directly to power plants.
