Why is there different time zones in different places? What's the time in your region?​
PSYCHO15rus [73]

Answer:

As Earth rotates, different parts of Earth receive sunlight or darkness, giving us day and night. As your location on Earth rotates into sunlight, you see the sun rise. ... Since different parts of Earth enter and exit daylight at different times, we need different time zones.

It's 2:45 PM here

How we could get people to turn off the lights in empty skyscrapers at night?
Svetlanka [38]
As I sat looking out at the city from Darling Harbour the other night, I noticed that nearly all the floors of the big office buildings had their lights ‘on’.

I compared the office buildings to large hotels and apartment buildings that had many of their lights ‘off’— obviously because people occupying those rooms and units turn the lights off when they’re not there. That makes absolute sense, doesn’t it? So why isn’t this same common sense not followed in office buildings?

I started doing some research online to find out. In this day and age when everyone is so conscious of the need to save energy in an effort to reduce carbon emissions, I thought surely there is a perfectly valuable and logical explanation to why all these lights are left ‘on’ at night.

To my surprise, this is what I found from various articles and blogs:

Office cleaning
Building security
Safety — so airplanes don’t hit the buildings
Surely cleaners don’t clean every floor at once all night long, not all lights need to be kept on for security reasons, and high-rise buildings have red blinking antennas on the roof to prevent planes from hitting them. These reasons weren’t convincing, so I dug a little deeper.

I found a study on overnight lighting in London’s non-domestic building stock by the Worcester Polytechnic Institute. Unfortunately, it explained that the data collected “did not provide reasons for overnight lighting”. However, the study did examine literature that suggests the following possible causes:

Diffusion of responsibility to others and authorities
People forget to turn lights off because they are stressed
Lack of motivation
Are diffusion of responsibility, forgetfulness due to stress and lack of motivation proper reasons for most city office buildings to be wasting so much energy every night?

If these truly are the reasons for leaving office building lights on, then the solution is simple ... let’s take responsibility and do something about it.

Take Action

You might work in one of those tall, bright buildings that shine at night. Why not take action and see if you can get the lights turned off on your floor or in the entire building. Here are some suggestions:

Talk to your manager, director, or CEO and ask them to encourage everyone to turn off the lights when they leave at the end of the day (as well as their computers and screens).
Talk to security and building services to ask if the security guards can turn any remaining lights off during their rounds once everyone is gone OR the office buildings could pay for someone to go through each floor turning off lights after everyone has left to eliminate the “I’m leaving them on for someone” excuse.
