According to Wikipedia, and I quote: "Earth Hour is a worldwide event that is organized by the World Wide Fund for Nature (WWF) and is held on the last Saturday of March annually, encouraging households and businesses to turn off their non-essential lights for one hour to raise awareness about the need to take action on climate change. Earth Hour was conceived by WWF and The Sydney Morning Herald in 2007, when 2.2 million residents of Sydney participated by turning off all non-essential lights.[1] Following Sydney's lead, many other cities around the world adopted the event in 2008."
There is no suggestion that people live without electricity for a month, etc.
It is essentially a noise making activity to sensitize consumers against wasting resources.
By even responding the now disappeared JonFrodo, and the one-time poster Vietaust, (someone should check their IP's) they have joined in the process.
What VietAust doesn't make clear is if he is quoting our anti-environmentalist from the U of G (most noted for it's farming research) or if HE IS the talking head.
Ignoring the world aspect, we in VietNam have a big problem. We try to use more electricity than there is available.
So even one person switching off a light in one part of VietNam enables another to use theirs. To my thinking that is good.
VietNam currently imports electricity from China, notorious for it's coal-fired generation. It also uses coal for generation in the north. Anyone who has visited Ha Long City can attest just how miserable the coal side is.
The rest of VietNam's power sources are hydro (water powered) and gas (from the ground). Wind-power and nuclear power are on our menu in the immediate future.
My home is in a have area, the Central Highlands is big in water and hydro-generation. A lot of the electricity consumed in TP HCM and environs comes from DakLak and Gia Lai.
VietNam has a very fragmented grid system, you can almost guarantee that no electricity generated in the north ever reaches the south and vice versa.
So any conservation, by switching off lights or turning down those water heaters, is like being a good neighbour.
I, personally, never use air-con. First, it put's a large dent in my pocket and secondly, it's rarely needed. Fans and building design work well.
In both my businesses and home I have small displays that show how much a room is consuming (easy when you wired the place and are a technician) and I think it's fair to say the three of us at home are very conscious of what we do and when.
No running power hogs at the same time. Washing done overnight, water heaters turned waaaay down, etc, I am not returning to the Stone Age but I am thinking of neighbours.
Similarly, in the office, almost all our lighting is LED, all our computers are powered by battery (security of supply) and float charged and the two large displays kitty corner in the main office let us know where we are overall. We are sensitised.
This string has done the same thing - making people think. Even if it means switching off the TV whilst you have a shower (no more Hanna Whatnot turned up high), it's win-win.
The idea of motivating youth, as near the Diamond Plaza today, means that a whole bunch of new emissaries will go home and start practising saving at home.
How bad can that be?
