On one of the very few warm evenings we had a couple of weeks ago my partner and I decided to go for a cold beer and relax outside at a local pub. Looking around at the nearby shops I saw that most of them had left some kind of lighting on to illuminate their signage, products or the whole of the inside or outside of the building.
Now, this is something that even as a child I thought was very wasteful, particularly as my parents were always really keen on switching off lights, radios, the TV etc when we weren’t using them. I remember once asking my dad why shopkeepers left all their lights on at night and he said “So if they get burgled you can see the burglar from the outside”. Of course he was teasing me and the real reason is advertising (I guess with an element of security too).
I was wondering, if those shopkeepers switched off the lights would they save enough money each year to spend on an alternative kind of marketing? More importantly what cost does this mean to the planet and how much energy could they save?
If like me you live near a city you will see very few stars because of light pollution, but this is just one of the less adverse effects of lighting up the sky. Wildlife is affected by this artificial illumination of the night time, it interferes with the natural behaviours of birds and the habits of plants and trees. At best its a nuisance and at worst it is an energy user contributing to climate change.
Not only were many of the shops near to our local pub lit up brightly but none of them seemed to be using low energy bulbs and at this time of year it doesn’t actually get dark until about 9pm. So from shop closing time at 5pm until 9pm those lights are burning away for absolutely no reason!

According to the Environment Agency England is more brightly lit than any other European country after the Netherlands. It seems however that other countries are making steps towards reducing this unneccesary waste. In June 2006 the mayor of Madrid signed a law ordering that all neon lights were switched off within a year and in Nov 2005 Rome began to lower street and shop sign lighting.*
The Environment Agency also tell us that “Light pollution may be regarded as a ‘nuisance’ under common law, and is being added to the list of statutory nuisances in the Environmental Protection Act 1990. Local authorities and people affected by light trespass will be able to take action, though there are specific exemptions for some transport and sports facilities.”
Is it just me or does that seem a little weak? Shouldn’t the law consider light pollution as something which will dangerously affect all of us rather than simply as a ‘nuisance’ to those who take the time to report it? Does that mean that if a shop or street light isn’t shining directly into my bedroom window then I have no right to complain about the wider problems that this misuse of light is causing?
I’d love to hear your views, rants or queries on this topic. Please get in touch or leave a comment.
