How does turning off unused electrical devices contribute to energy conservation?

This question was previously asked in
RRB NTPC 2024 Undergraduate CBT 1 Question Paper (29-Aug-2025) (Shift 1)
The correct answer is

By lowering utility bills

Turning off unused electrical devices contributes to energy conservation primarily by reducing the overall energy consumption. When these devices are left on, they continue to draw power, which results in unnecessary energy use. By switching them off, households and businesses can:

  • Reduce Energy Waste: Devices not in active use still consume electricity if left on, often referred to as standby power or phantom load. Turning them off prevents this wastage.
  • Lower Utility Bills: As energy consumption decreases, the cost incurred for electricity also drops. This leads to significant savings over time, making it a cost-effective practice.
  • Extend Device Lifespan: Regularly turning off devices can potentially enhance their longevity by reducing wear and tear associated with continuous operation.

The correct answer to the question is: By lowering utility bills.
