Purpose of Earth Hour:

The purpose of Earth Hour is not to save energy for just one hour but to raise awareness about the importance of reducing our carbon footprint and taking action to combat climate change. The event is also a reminder that we can all make small changes in our daily lives to reduce our impact on the environment. For example, turning off lights and other electrical appliances when not in use, reducing our use of plastic, and choosing to walk or cycle instead of driving.

In addition to individuals, businesses, and governments also participate in Earth Hour by turning off non-essential lights in their offices, shops, and public buildings. This sends a strong message to policymakers that people care about the environment and want to see action on climate change.

Over the years, Earth Hour has inspired a range of environmental initiatives and campaigns, from banning single-use plastics to promoting renewable energy sources. The event has also helped to raise awareness about the urgent need to take action to combat climate change, which is one of the biggest challenges facing our planet today.

Despite the challenges posed by the COVID-19 pandemic, Earth Hour continued to be observed in 2020 and 2021, with millions of people participating online and from their homes. This demonstrates the resilience and determination of the global community to continue the fight against climate change.


In conclusion, Earth Hour is an important annual event that raises awareness about climate change and encourages individuals, businesses, and governments to take action toward a more sustainable future. While turning off the lights for one hour may seem like a small act, it sends a powerful message that together, we can make a difference in protecting our planet.
