Have you ever heard that using CFL in place of incandescent light would be better ?
Have you ever thought what could be the precise reason for that ?
What is the prime purpose of having a bulb for ?
Apparently it is for getting light.
Consider an incandescent light. If we give 100% of energy to an incandescent bulb, 90% of this energy is utilised for generating heat energy (which is not at all our purpose) & 10% is used for generating light energy.
Now consider a CFL bulb. If we give 100% of energy to a CFL bulb, (30-40)% of that energy is utilised for generating heat energy & (60-70)% is used for generating light energy.
The above two statements aptly explains why CFL has an upper hand over incandescent bulb.
Other points that can be made out are
1) CFL lasts 10 times longer than an incandescent bulb.
2) CFL uses 1/3 rd of the energy used by an incandescent bulb to produce same amout of light, which implies that electricity bill on CFL would be 1/3 rd of that of an incandescent bulb.
3) In fact by using CFL, in place of incandescent bulbs, we can prevent greenhouse gas emission to some extent. Wonder how ?
Where do we get electricity from ? Mostly 70% of the electricity that we use is generated from thermal stations by burning coal, which release greenhouse gases into atmosphere. If we use less energy(by using CFL), this indirectly implies that we are preventing greenhouse gas emission to some extent.
NOTE: Comparison was made only between CFL bulb and an Incandescent bulb. LEDs were not compared above. It would have revolutionised the entire article if comparison was made.
