Simple Test on Energy Storage Systems

What is the most common energy storage system?

• Gravitational energy storage

• Rechargeable batteries

• Seasonal thermal storage

• Pumped-storage systems

How do rechargeable batteries store energy?

• By moving solid weights up and down

• By using a chemical reaction

• By storing water in reservoirs

• By collecting solar energy

What is the purpose of a pumped-storage system?

• To store heat underground

• To store energy using solid weights

• To use water movement to generate electricity

• To power small devices like phones and laptops

Which energy storage system is similar to old clocks?

• Pumped-storage system

• Rechargeable battery

• Gravitational energy storage

• Seasonal thermal storage

How does seasonal thermal storage work?

• By heating large underground reservoirs of water for later use

• By storing electricity in huge batteries

• By moving water between two reservoirs

• By using solar panels to generate power
