Detailed Solution

The above statement is true.
The electrical bulb uses more electricity and wastes energy in the form of heat compared to the CFL. Compact fluorescent bulbs(CFLs), on the other hand, do not waste electrical energy in the form of heat and consume less energy. In addition, reflecting material is used inside the CFL to produce more light, which makes the CFL use less amount of electricity to produce more light.
