Celebrating The Earth Hour Tonight From 8:30 PM To 9:30 PM

Initiated by the World Wildlife Fund, it occurs on the last Saturday of March every year from 8:30 PM to 9:30 PM. The emblematic endeavor began in 2007 in Sydney, Australia, when the WWF encouraged 2.2 million people to switch off their lights for one hour to aid the move on environmental change. From that point onwards, a huge number of people around the globe have participated. Tourist spots, for example, the Eiffel Tower, Big Ben, Sydney Opera House, the Empire State Building, Buckingham Palace, the Colosseum and Edinburgh Castle have gone dark for 60 minutes.

Earth Hour is an yearly activity wherein people switch off their lights to spread mindfulness about sustainability and environmental change.

It’s intended to unite individuals who share one shared objective: Reduction of light pollution.
Light Pollution is unnecessary, misled, or artificial light. Light pollution has many negative results: it cleans out starlight in the night sky, meddles with cosmic research, upsets biological systems, has unfavorable health impacts and squanders energy.
Somewhat more than 100 years prior, you could stroll outside around night time even in a city and see the Milky Way galaxy curve over the sky. Being able to see a large number of stars was a piece of regular day to day life, rousing artists like Van Gogh or melodic composers like Holst or scholars like Shakespeare. By permitting artificial lights to clean out our starry night skies, we are putting some distance between our social legacy. We are additionally putting some distance between what could motivate people in the future.
With the greater part of the total populace presently living in urban communities, 3 out of each 4 individuals in urban communities have never encountered the wonderment of perfectly dark skies. How would you clarify the significance of what they’ve lost to light contamination? How might you make them mindful that light pollution is a worry on numerous fronts: wellbeing, energy preservation, cost, health and impacts on wildlife, just as our capacity to see the stars? At long last, how would you persuade them that it’s beneficial to find a way, to help fix this issue?
In disturbing biological systems, light pollution represents a genuine danger specifically to nocturnal natural life, impactsly affecting plant and animal physiology. It can befuddle the migratory patterns of animals, change serious connections of creatures, change predator-prey relations, and cause physiological mischief. The musicality of life is arranged by the characteristic diurnal examples of light and dark; so interruption to these patterns impacts the environmental elements.
Concerning antagonistic health impacts, numerous species, particularly humans, are reliant on natural body cycles called circadian rhythms and the creation of melatonin, which are managed by light and dark. On the off chance that people are exposed to light while sleeping, melatonin production can be smothered. This can prompt sleep disorders and other medical issues, for example, expanded cerebral pains, weariness, stress, a few types of obesity because of absence of rest and increased anxiety. Also, attaches are being found to two or three sorts of cancer. There are additionally impacts of glare on aging eyes. Health impacts are not just due to over-illumination or inordinate exposure of light over time, yet in addition inappropriate spectral composition of light.
As for energy wastage, lighting is responsible for in any event one-fourth of all power utilization around the world. Over illumination results in energy wastage, particularly upward coordinated lighting around night time. Energy wastage is additionally a loss in cost and carbon footprint.
Fortunately light pollution can be decreased effectively by shielding lights appropriately, by utilizing light when and where it is required, by just utilizing the sum that is required, by utilizing energy proficient bulbs, and by utilizing bulbs with suitable spectral power distributions for the task needing to be done.
Earth Hour has grown to engage more than 7,000 cities and towns across 187 countries and territories to raise awareness for energy consumption and effects on the environment.
A 2014 study published in Energy Research and Social Science compiled 274 measurements of observed changes in electricity demand caused by Earth Hour in 10 countries, spanning 6 years, and found that the events reduced electricity consumption an average of 4%. The study noted the policy challenge of converting Earth Hour’s short-term energy saving into longer-term actions, including sustained changes in behaviour and investment.
According to WWF, in 2008, Thailand decreased electricity usage by 73.34 megawatts, which, over one hour, is equivalent to 41.6 tonnes of carbon dioxide. The Bangkok Post gave different figures of 165 megawatt-hours and 102 tonnes of carbon dioxide.
Philippine Electricity Market Corporation noted that power consumption dropped by about 78.63 megawatts in Metro Manila, and up to 102.2 megawatts on Luzon. The maximum demand drop of around 39 MW was experienced at 8:14 PM in Metro Manila and of around 116 MW at 8:34 PM in the Luzon grid.
In 2009, Philippines was able to save 611 MWh of electricity during the time period, which is said to be equivalent to shutting down a dozen coal-fired power plants for an hour.
Ontario, Canada used approximately 900 megawatt-hours less electrical energy during Earth Hour. At one point, Toronto saw an 8.7% reduction in consumption as compared to a typical March Saturday night.
Ireland, as a whole, had a reduction in electricity use of about 1.5% for the evening. In the three-hour period between 6:30 PM and 9:30 PM, there was a reduction of 50 megawatts, saving 150 megawatt-hours, or approximately 60 tonnes of carbon dioxide.
In Dubai, where external lighting on several major city landmarks was turned off and street lighting in selected areas was dimmed by 50%, the Electricity and Water Authority reported savings of 100 megawatt-hours of electricity. This represented a 2.4% reduction in demand compared to before the hour began.
The best result was from Christchurch, New Zealand, with the city reporting a drop of 13% in electricity demand. However, national grid operator Transpower reported that New Zealand’s power consumption during Earth Hour was 335 megawatts, higher than the 328 megawatt average of the previous two Saturdays. Melbourne, Australia reduced demand by 10.1%. Sydney, being the city that participated in both the 2007 and 2008 Earth Hours, cut electricity consumption by 8.4%.
Swedish electricity operator Svenska Kraftnät recorded a 2.1% decrease in power consumption from its projected figure between 8 PM and 9 PM. The following hour, the corresponding number was 5%. This is equivalent to the consumption of approximately half a million households out of the total 4.5 million households in Sweden.
In Vietnam, electricity demand fell 500,000 kWh during Earth Hour 2010, which was three times larger than the first time the country joined the event in 2009.
30 provinces and cities in Vietnam took part in Earth Hour 2011 with the main event held in Nha Trang. Vietnam managed to save 500 Million VND ($23,809).
Turn off the lights tonight from 8:30 PM to 9:30 PM for a eco-friendly and sustainable present and future.
