What best describes solar energy in residential and utility-scale installations?

• A. Energy harnessed from the Sun using solar panels or solar cells to generate electricity.
• B. Energy produced by burning coal with scrubbing.
• C. Energy stored as chemical energy in fossil fuels.
• D. Energy derived from hydroelectric dams.

Answer: (A)

Solar energy in homes and utilities means turning sunlight into electricity using solar panels or solar cells. Photons from the sun hit the semiconductor materials in these devices and create an electric current, which can be used on-site or fed into the power grid. In residential setups, rooftop panels convert daylight into electricity for household use and sometimes export excess power. In utility-scale installations, large arrays or concentrating solar power systems capture sunlight over many acres to generate large amounts of electricity for grid supply. This approach is distinct from energy produced by burning fossil fuels or from hydropower, as those involve different energy sources and processes.
