Am I being dim over street lights?

Has anybody noticed that certain street lights have been dimmed?

Does anybody care?

I am not sure if Fourth Avenue was part of the trial, but there are five not working down there.

Sorry, the lights were dimmed not switched off altogether were they.

I must admit I am having trouble working out how dimming lights can save money.

For example, if I turn my living room light on for eight hours and it costs one penny an hour in electricity then I have spent eight pence.

Then, if I turn my living room light on for eight hours the following day, but turn the dimmer switch on, I am still being charged 1p per hour. The only difference being the room is not as bright.

Or can my electricity meter suddenly work out what I am doing and charge me accordingly.

I can understand the enviromental aspect of it, but to be honest does anybody actually give a stuff about saving the planet?

I appreciate the council has to do “its bit” in relation to carbon footprints and the like, but what is saved in one hand is lost in the other.

A prime example are the Bar Walls where certain parts of the walls are floodlit from early evening till late at night. Why?

At this time of year the vast majority of us just want to get home for our tea, not gawp at a floodlit pile of stones.

I am not suggesting the city be plunged into darkness, but double standards seem to be the order of the day. Practise what they preach needs to be applied.

High street shops take great delight in telling us how much they care for this and that. They think by not giving out carrier bags they are making a massive difference.

What they should do is turn overhead door heaters off during the day – or at least close the doors while they are on. Better still, turn neon window shop lights off at night.

Traffic lights are another waste of electricity especially during the early hours of the morning.

I was always under the impression that they worked on a sensor system so if you approached at a red signal a sensor would turn them to green if it was safe to do so.

The amount of times I have waited at Layerthorpe, Monk Bar, Exhibition Square and Leeman Road in the early hours, while the lights go through the complete cycle, suggests the sensor theory does not exist.

I noticed the lights were out the other month at Lords Mayors Walk. Traffic flowed freely as people actually helped each other and gave way.

Is it worth exploring the possibility of switching some traffic lights off and seeing what happens?

I waste money at home. I leave everything on standby. It is pure idleness on my part, picking up the remote control and flicking on the telly is second nature.

Bending down and flicking a switch at the wall is far too difficult.

Having said that, TV manufacturers should stop supplying remote controls and make us idle sods get off our backsides once in a while.

Going back to the street lights, if it is economical to dim them, then fair play to whoever had that idea.

However, could someone have a look at the trees that often overshadow street lights in residential areas and maybe have a prune every couple of years?

Trees in full leaf block out so much of the light from lampposts – even more if the lights are to be dimmed en-masse.

If not, then false economy is being applied as the job of the street light is being hampered by Mother Nature.

Save money and the planet to boot, but make sure the hymn sheet is open at the right page and everybody is singing from that page.

am i being 'dim' in suggesting you don't get charged per hour, but instead per kWh? if you get charged per hour, you would surely have to disconnect your entire home electricity system in order not to be charged at all

Yes, you are being dim. Go and Google "understanding KWH" Failing that sign up at night class to do a GCSE in Physics or General Science, It used to be covered in the syllabus.

Sorry Paul, you are dim. You use less electricity, you get charged less. Your meter will know, that’s why you have it.

I can just imagine him sat at home with every electrical item on at once thinking that if he has got his electricity on, he might as well use everything!

jassy seems to have joined in the dimness - as the name suggests, a kwh is use of a kilowatt of power for an hour, therefore if you reduce the amount of power, say by half, it takes twice as long to accumulate the same number of kwh's, and hence the same cost

it's not rocket science... or are you now gonna suggest i take up a course in that too?

In Selby, they're using the approach of not fixing lights that aren't working - I don't know if this is deliberate or just neglect, but it does make it very difficult to see pedestrians in some places.

So tcs you are saying the council are going to put the lights on for twice as long thus negating any saving by reducing power consumption?

Paul you have some good points ,the council rarely trim back trees nowadays,whether they are over lamposts or overshadowing properties ,probably to save money.And same with the shops using all the being green friendly talk about packaging ect with 20 tellys on in the background on the same channel.

jassy, you really don't get it do you. im responding to paul's idea that an electricity meter goes up by the same amount regardless of how much electricity is being used, so long as some is being used. you're the one who patronisingly told me to study kwh's, im tempted to pass the same advice back to you

tcs you seem to be one a bit mis informed, its dark for the same amount of time therefore you use less kw per hour over that time if something is turned down and therefore less electricity. Fairly simple eh?

yawn.., york says...

Picture your dimmer switch (a variable resistor) as a single speed pedal cycle, and your electric meter as an odometer (mileometer). Put simply, if you pedal half as fast as normal it will take twice as long to cover a mile. Similarly, if you turn your light down by 50% (half), and provided that light was all you were using in a comparison, then it would take twice as long for your electric meter to register precisely 1KWh.. Oh for a world class economist.!

True to say though, I'm not such a fond lover of the council's "bright" idea in turning the street lights down (quite so much at least). I am curious to know what kind of bulbs light up our streets. The average 'incandescent' for example, wastes I believe about 80% of its energy creating heat. Most traffic signals seem now to have gone over to led's instead of bulbs, which are of course much more reliable and efficient. In addition, I feel pretty certain that led's could be run off a small bank of batteries that could be charged by an inexpensive photosensitive cell negating the need to have street lighting connected to the national grid.. I could be wrong.

FOR HEAVEN'S SAKE, DO I HAVE TO SPELL IT OUT?!

a kwh is use of a kilowatt of power for an hour, therefore if you reduce the amount of power, say by half, it takes twice as long to accumulate the same number of kwh's, and hence the same cost

i suppose i have to add, since you're all so dim, that by implication, if it takes twice as long to accumulate the same cost, the cost over the given period of time is half of what it was - hence cutting cost by reducing power used - hence the purpose of dimming the lights

IT
IS
NOT
DIFFICULT
!!!!!!!!!!!!!!!!
