From what sources can we get power?

• A. Solar
• B. Batteries
• C. Nuclear
• D. Commercial and generator

Answer: (D)

Power for most buildings and devices comes from two practical sources: the commercial electrical supply (the grid) and a generator. The grid is the network that delivers electricity generated at central plants to homes and businesses, making it the standard, continuous source of power. A generator serves as an on-site alternative when the grid isn’t available or when you need backup power, such as during outages or in remote locations. Solar, batteries, and nuclear describe ways to generate or store electricity, but they’re not the everyday, universally accessible sources you rely on in normal operation in the same way the grid and a generator are. Solar and nuclear produce power under certain conditions or at larger scales, while batteries store energy rather than provide a continuous source by themselves.
