this

technological advancement is helping to increase the energy efficiency.

Firstly

this

invention is not very new from a technological perspective. A smaller version of these devices has been in use since the beginning of 1980s, with less brightness and at limited use case scenarios. Later it was undergone to various researches and developments.

For example

, LED based torches were available since the beginning of 2000s.

Further

developments helped to spread it out to various sectors. Now a days incandescent lamps are being replaced at a faster pace in our home lighting, and

also

in industrial locations.

Furthermore

, these LED devices are energy efficient, so that a significant reduction in the requirement of electricity for the home or industrial purpose.

For instance

, in earlier days an incandescent lamp needed 100 wattage to brighten a room significantly,

on the other hand

an LED lamp of 9 wattage could do the same. It shows that

this

modern invention significantly reduces the electricity requirement. In conclusion, I think the modern world has an edge over the yesteryear technologies in effect reduced the power requirement,

this

certainly benefiting our society.

As a result

, incandescent lamps are replaced with Light Emitting Diode based light-sources which are much more energy efficient, in essence reduces the power usage. It has been proved that

this

Write a letter to a museum's manager after visting the museum. Give some advice for improvement as you had a mixed experience.
I am writing this letter to share my mixed experience with you after visiting the London's history museum. Last week, I decided to visit this great museum with my few close friends. As the website of your museum has mentioned that enterance is allowed after 9am, we arrived on the ticket counter around 10:00 am. However, the gate keeper did not allow the entrance till 11 am. Moreover, the customer service was not satisfactory in the museum, as there was no tourist guide available for the local community. In my opinion, the opening and closing time of the museum should be same on both website and enterance gate of the place, otherwise it will harm the reputation of your place.

Many high-level positions in companies are filled by men even though the workforce in many developed countries is more than 50 percent female. So, companies should be required to allocate a certain percentage of these positions to women. To what extent do you agree or disagree?
With the development of gender equality sentiments, an increasing number of employees are women recently. However, an unfair social fact is that most advanced-level positions still prefer males, still has been common. Ergo, some individuals have proposed that companies are responsible for following a new rule, which allocates a certain percentage of high-level positions are women. In this essay, I will explore both sides of this proposal by highlighting positive and negative aspects, arguing for a balanced view.

Some people think that a sense of competition in children should be encouraged. Others belive that chikdren who are taught to cooperate rather than compete become more useful adults. Discuss both these views and give your opinion.
In this cutting age era, some individuals believe that child should be encouraged to compete with other children, while other argue that they should grow up without competing with others. Infact they should learn how to cooperate, which can lead them to get success. From my perspective, encouraging competition from early age can be more beneficial because nowadays almost all work need a great effort and competing with others make them achieve great things in life.
