best off
We all seem to have our bugbears with regard to consumerism and capitalism. I've been inspired to have a wee rant about mine after Maff revealed his disdain for carrier bag addicts and the Bro voiced his disdain for corporate fatcats.
Electric lighting. Very useful, I'm sure we'd all agree. However, useful does not equate to essential or default. So why is it, then, that virtually every household I visit are under the illusion that lights, once on, are un-turn-off-able?
Most people I know talk a good game about caring for the environment. (I don't doubt them, either. And I'm aware we're all riddled with contradictions. I, for instance, use more than my fair share of water but still have this incredibly strong principle about power wastage. But rants, as is tradition, ignore such hypocrasies, so let the tirade continue...) Yet, despite their vocal intentions, they seem to think leaving lights on all night, or TV's, or radios, etc, is perfectly OK.
When there is an excuse, it's usually "I'm going back in there in a minute".
SO?! Will it really take that much energy (your energy, not the planets) to flick the switch back on?
More often than not though, there's no excuse and its just plain selfish laziness that prevents said power-draining planet killer from being turned off. People just leave a room and turning off the light doesn't even cross their mind. It really is incredibly selfish. There's no way you can justify such wanton waste, such blinkered consumption. However many joules it takes for you to move your finger and flick the switch is infintessimally smaller than however many kilowatts of power it takes to sustain the illumination of the room you're not occupying. And if you think it's too much effort, or you 'like a room to be light when you enter it', then you have a hugely inflated sense of self-importance.
Like I mentioned earlier, there's a sense that it's just default that lights are left on, that there's not even a problem there. It's a bit like drinking and smoking - many people are barely aware that they are drugs as it's so socially acceptable. I feel like shaking such head-in-the-sand drinkers, smokers and power wasters and shouting, "WAKE UP!!"
Power comes from the consumption of precious resources which in turn pollutes the environment. It's not just there, like magic.
"leaving a light on doesn't use that much power, surely!"
It uses more than fucking nothing, and thats what a light uses when its switched off. Switching off lights must be the single most simple way a 'talks the talk' environmentalist can start walking the walk. Right?
John, I challenge you to find a stat about how much power would be saved if everyone in the country turned thier lights off. I tried, but my stat radar isn't as honed as yours. Also, is there any truth in that old statement that turning a light on/off uses more power than leaving it on all night?
My final point relates to money. In that you can save it by saving power. Especially relevant if you live in a shared house. However, if it's this point that makes your ears prick up and becomes your primary motivation to save power then you're more lost in the consumerist/capitalist structure than this post assumed.

I HAVE SOME LIGHT FACTS!
Fistly, lets clear up an argument that people put about whether it saves more energy not to turn some light off due to the power surge it takes to fire them up in the first place (we are talkin incandescent/flourescent lights here).
For Flourescent lights, they should be left on unless you will be out the room for 15 minutes or more. This is because of the power taken to fire the light up and also the loss of life the light will have as a result. Apparantly if a flourescent light is used for 3 hours before shutting it down each time, it will last 20000 hours. if its used 6 hours each time before shutting it off it will last 24000 hours. The balanced view therefore seems to be for power saving and light bulb saving, keep them on for 15-20 minutes at a time.
However, another source suggested the extra power used to turn these kind of lights on only accounts for the same as having the light on for 5 seconds, so the main reason to leave them on at least 15 mins is to save the bulbs/
For normal household lights, it should be turned off if you will be out the room for more than 5 minutes.
FACTS!
On the question of how much would be saved if everyone turned lights off, there is no direct stats! But, I have some info which should give the idea of the problem.
1) Lights account for 25% of overall energy use.
2) Everyone should put energy saving bulbs in the house - they use 60% less of the energy and last 10 times as long. BUY SOME NOW
3) 7% if UK carbon emissions are from lights
4) If everyone turned their TV off at the switch it would save enough power to do the countries street lights. AND if everyone just turned the TV off at the switch at night, it would save enough power to power the whole of a town the size of Basingstoke.
FACTS!
So there you go, no direct answer, but lights are a problem. Everyone should get energy savers. Everyone should turn normal lights off if they will be out the room for 5 mins, and flourescent if out the room for 15 minutes. Everyone should turn electrical things off at the switch.
So there.
Personally I think the worst culprits are businesses who leave lights on all night. Completely unnecersary and a complete waste of power. Last time I was in London I noticed the Town Hall (where the mayor hangs out) is a new plush glass building. every light was on! Shocking.
Lights are bad, so are all other electrical things. Seems energy saving light bulbs should be the main thing people concentrate on.
