In the question given below, there are 2 statements marked as Assertion (A) and Reason (R). Choose the correct alternative from the following options.

Assertion (A)- Nowadays LED (Light Emitting Diode) lamps are promoted throughout the country for achieving energy efficiency.

Reason (R)- The LED bulb uses one-tenth energy as an incandescent bulb and half as much as a CFL to produce the same amount of light.

Both (A) and (R) are true and (R) is the correct explanation.

According to the Bureau of Energy Efficiency (BEE), CFLs consume 80 percent less power as compared to ordinary bulbs. As put by a CFL manufacturer, Indo-Asian, the replacement of one million 100-watt bulbs with 20-watt CFLs can
save 80 megawatts in power generation. These days LED (Light Emitting Diode) lamps are promoted throughout the country to save energy. The LED bulb uses one-tenth energy as an incandescent bulb and half as much as a CFL to produce the same amount of light. According to Energy Efficiency Services Ltd, the UJALA scheme that aims to replace incandescent bulbs with LEDs could save 5,905 MW in power generation. This translates to an annual savings of Rs. 4,000 for an average family due to efficiency gains and lower replacement costs.
