I WONDER - Does Changing Lightbulbs Affect Energy Usage?

The video tutorial explains the importance of replacing burnt-out light bulbs with energy-efficient options like compact fluorescent light bulbs (CFLs) and light-emitting diodes (LEDs). These bulbs are more energy-efficient, using up to 75% less energy, and last significantly longer than standard bulbs, offering both economic and environmental benefits.

What should you do when a light bulb in your house stops working?

• Call an electrician immediately.

• Replace it with an energy-efficient bulb.

• Leave it as it is.

• Replace it with a candle.

Which of the following is a type of energy-efficient light bulb?

• Incandescent bulb

• Halogen bulb

• Neon bulb

• Compact fluorescent light bulb

What does LED stand for?

• Light Energy Device

• Light Emitting Diode

• Light Emitting Device

• Light Energy Diode

How much less energy can CFLs and LEDs use compared to standard bulbs?

• 25% less

• 50% less

• 75% less

• 100% less

How many times longer can CFLs and LEDs last compared to traditional bulbs?

• 15 times longer

• 20 times longer

• 10 times longer

• 5 times longer
