A student researching electric grid modernization has taken the following notes:
• Smart grids use digital technology to monitor and manage electricity flow • Traditional grids are one-directional from power plant to consumer • Smart grids enable two-way communication and can integrate rooftop solar • The technology can detect and respond to outages in real time • Smart meters allow consumers to monitor and adjust their energy use
The student wants to contrast smart grids with traditional electrical grids. Which choice most effectively uses relevant information from the notes?
Smart grids use digital technology to monitor and manage the flow of electricity efficiently.
Unlike traditional one-directional grids, smart grids enable two-way communication, allowing integration of rooftop solar and real-time outage response.
Smart meters allow consumers to monitor and adjust their energy use based on real-time data.
Smart grid technology can detect and respond to power outages in real time.
Correct Answer: B
Choice B. Contrasts one-directional vs. two-way communication to show differences.
