Every year on the last Saturday of March, at 8:30 pm, millions of people all over the world turn off the lights for an hour for the betterment of the earth. This day is known worldwide as Earth Hour Day. This year Earth-Hour day is on 27th March.
This Year Theme
This year World Wide Fund for Nature have set the theme “Climate Change to Save Earth” for Earth Hour Day.
On this occasion, people in more than 190 countries of the world will switch off the lights of their homes from 8.30 pm to 9.30 pm and give a message of solidarity to save the earth by saving energy.
Experiments are being done around the world to create and save electricity from new resources. Until now, solar energy was able to be used only in sunlight, but now researchers from Sweden have made it useable even when there is no sunlight. By collecting solar energy, they have prepared a kind of fluid that can be used when the sun is not illuminated. Scientists claim that this fluid can be kept safe for months and years and it will be usable if needed.

When Did Earth Hour Begin?
Earth Hour was launched in the year 2007 by the World Wide Fund for Nature (WWF). It is an environmental campaign aimed at drawing people’s attention towards climate change.
On 31 March 2007, Earth Hour Day was celebrated for the first time. It was first held in Sydney, Australia. Where, people were requested to switch off all the lights for 60 minutes. Gradually it began to be celebrated worldwide.
The World Wildlife and Environment Organization (WWF) is an organization that is said to be the world’s largest “independent conservation organization”. Currently there are more than 5 million people in more than 100 countries supporting the organization. The purpose of this institution is to prevent the loss of nature and to improve the future of mankind.
In 2009, India became a part of this campaign. The leading names are the Reserve Bank of India and Air India buildings as well as educational institutions such as Delhi University and Jamia Millia Islamia participated in this hour.
BSES will turn off the non-essential lights during Earth Hour at its over 400 offices in New Delhi. A BSES spokesperson says that the Corona epidemic and climate change have increased the crisis of the earth, which everyone will have to make efforts to stop.
