I was just thinking whether the substitutes for lighting during the earth hour are ecological and about the general efficiency of the act. This is all again just speculation and just a proof of one individual having an opinion and showing his/her awareness.
What i think is that if you switch off your lights, you shouldn't light a candle instead because of them producing CO2. If you wanted to be ecological you'd use LED if any lights. Some cities also switched off lights from lighting buildings and other public places. However most of those lights use gas discharge lamps which consume huge loads of voltage when switched on compared to what they use for just being on. Same applies for fluorescent lamps. Only incandescent lamps use the same amount of power when switched on and being on, but you definitely shouldn't replace them with candles.
Just to make a point here. I think the earth hour makes a difference, atleast in the statistics and therefore is enough to be a step down the right path. However i think the main effect is psychological, ie. making people think about the status quo and their own manners.
Another fact is that about 85% of produced electricity is used by industry. So would it be also easier to cut down emissions and electricity consumption from the bigger "half"? Just a thought.
This is really off topic and no offence to anyone but what i often think when those people (in finland called "facers" or something) representing some charity organization (UNICEF, WWF, Greenpeace, you name it) ask you to donate money for a good cause, is that why they ask for the money from the relatively poor individuals on the street and not (and i am not 100% sure they don't) the bigger instances like governments and supranational companies who are more likely to be responsible for the problems of the world...?
The answer is because on the whole we don't think and we don't care. In the end We are the people responsible for those actions and those companies and governments to exist and last and the foremost responsible of our own daily actions. It's useless to think whether one's actions make any difference. Do the choice for good if not for the environment or statistics, then do it for the sake of ethics. :)
Peace out. And love.
