What is the term for capturing and storing energy for use during periods of low generation?

• A. Storage
• B. Energy storage
• C. Conservation
• D. Retention

Answer: (B)

The idea being tested is balancing variable energy generation by saving power for later use. Energy storage is the standard term for systems and technologies that capture energy when it’s plentiful and release it during times of low generation. This can involve storing electrical energy in batteries, pumped hydro, thermal storage, or other forms, then delivering that energy when demand is high or winds/sunlight are low. It helps renewables provide a steadier supply and supports grid reliability. The other terms are less precise in this context: storage is too general, conservation focuses on reducing use, and retention isn’t the established term for saving energy for later.
