Which approach best describes demand-side management for energy scarcity?

• A. Demand response, time-of-use pricing, energy efficiency measures, and smart-grid technologies to shift or reduce consumption.
• B. Increase fossil fuel subsidies.
• C. Build more power plants regardless of demand.
• D. Ban electricity usage during peak hours only.

Answer: (A)

Demand-side management is about shaping how people use energy, not just boosting how much we can produce. It relies on incentives, price signals, efficiency, and technology to reduce or shift consumption so the available supply fits within scarcity limits. The best approach brings together demand response (getting people or devices to cut or move energy use when conditions require), time-of-use pricing (charging more during peak times to encourage shifting), energy efficiency measures (lowering the total amount of energy needed for the same activities), and smart-grid technologies (real-time monitoring and control that coordinate loads and integrate variable supplies). This combination directly lowers peak demand and makes energy use more flexible and reliable during shortages.

The other options focus on increasing supply or imposing broad, blunt restrictions rather than actively shaping consumer demand, which is why they don’t fit as well.
