- 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, replacement of one million 100-watt bulbs with 20 watt CFLs can save 80 megawatt in power generation. This amounts to saving Rs 400 crore.
- 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 the 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.

Consider the following statements.1. The LED bulb uses one-tenth ener...
Statement 1: 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.
Statement 2: CFLs consume 80 percent less power as compared to ordinary bulbs.
Explanation:
Both statements are correct.
Statement 1: 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.
LED (light-emitting diode) bulbs are known for their energy efficiency. They use significantly less energy compared to incandescent bulbs and CFLs (compact fluorescent lamps) while producing the same amount of light. LED bulbs use semiconductors to convert electricity into light, whereas incandescent bulbs use a filament that produces light as a result of heat.
The statement correctly states that an LED bulb uses one-tenth of the energy of an incandescent bulb to produce the same amount of light. This means that LED bulbs are much more energy-efficient and can help in reducing electricity consumption.
Additionally, the statement also mentions that LED bulbs use half as much energy as a CFL to produce the same amount of light. This is because CFLs generate light by passing an electric current through a tube filled with gas and coated with phosphors. While CFLs are more energy-efficient than incandescent bulbs, LED bulbs are even more efficient.
Statement 2: CFLs consume 80 percent less power as compared to ordinary bulbs.
This statement is also correct. CFLs are known for their energy-saving properties. They consume approximately 80 percent less power compared to traditional incandescent bulbs. This means that CFLs can produce the same amount of light while using significantly less electricity, resulting in energy savings and reduced electricity bills.
In summary, both statements are correct. LED bulbs use one-tenth of the energy of incandescent bulbs and half as much energy as CFLs to produce the same amount of light. CFLs consume approximately 80 percent less power compared to ordinary incandescent bulbs. These energy-efficient lighting options are crucial in promoting sustainability and reducing energy consumption.
