ELECTRICITY USEAGE

Now read this!!! 

I have no idea what the schools electricity consumption is, but, I do know that we waste an awful lot of it by leaving things turned on when they are not needed (lights,PC's etc). Every member of the school community can help to reduce the amount of electricity we use simply and easily by turning off lights and equipment when they have finished with it. If lots of people make a little effort it could end up making a big difference.

I will try to record our electricity consumption on a Friday so that we can see the results on a week-to-week basis, but first of all it's time for a quick physics lesson!

 Electricity consumption is measured in Kilowatt Hours (Kw/h). To find out how much electricity something uses all you have to do is multiply the electrical rating of the appliance in Kilowatts (1Kw=1000watts) by the time that it has been in use (in hours). So, for example, a 60 watt light bulb switched on for 6 hours is : 0.06Kw x 6h = 0.36Kw/h. A vacuum cleaner with a 650 watt motor, used for 15minutes would be 0.65Kw x 0.25h = 0.162 Kw/h.

All you have to do now is watch this space :-)

 

Friday 8th Jan 2010. I have taken some base readings and, this week the school has used 9170 Kw/h. It will be interesting to see how much this figure rises when the school re-opens next week.

 

Friday 15th January. School is open again and this week we have used 14 003 Kw/h. To be honest, that's not as much as I was expecting. Over the next few weeks we should be able to gauge weather this figure goes up or down or remains constant.

 

Friday 22nd January. This week we have used 17 729Kw/h. As this has been the first full week back , this will probably prove to be an average figure for the time of year.

 

Friday 29th January. A saving this week, we have used 16 408Kw/h :-)

 

Friday 5th February. Lots of extra events this week so it's no suprise consumption is up a bit. 17 953Kw/h :-( (highest reading so far)

 

FRiday 12th February. Oh dear! for the second week in a row we have a new highest reading 18 243Kw/h :-(

 

Friday 19th February. Half term week so no suprise that electricity use is down, infact almost half of last weeks total. 9 363Kw/h.

 

Friday 26th February. We have made a masive saving this week, lets see if we can keep it going. (drum roll) 15 250Kw/h :-)

 

Friday 5th March. This weeks readings are on the low side of average. 16 343Kw/h.

 

Friday 12th March. About average again this week. 15 852 Kw/h.

 

Friday 19th March. Another good week, and a small saving. The school has used 15 585Kw/h :-)

 

Friday 26th March. An amazing week, the Earth hour day was a great success  and helped the weeks electicity reading plumet to 13 998Kw/h :-)

 

Friday 16th April. Over the Easter break we have used 23 584Kw/h in total, thats an average of 7861Kw/h per week :-)

 

Friday 23rd April. A good start to the term, we have used 10 224Kw/h this week :-)

 

Friday 30th April. Lots of things going on in the Assembly hall this week that required extra power and lighting. 13688Kw/h used

 

Friday 7th May. 12511 Kw/h used this week. :-)

 

Friday 14th May. This week we used 14709Kw/h. There have been a lot of functions this week which probably accounts for the rise in electrisity use, this may well be the start of a trend untill the end of term.

 

Friday 21st May. This week we have used 13256Kw/h :-)

 

Friday 28th May. It's been a quiet week in school andour electricity usage is down accordingly. 11 557Kw/h.  :-)

I wonder how we managed to make asaving ? I think there's a lot more we can all be doing - by just being less wasteful Grrreen Club girls are trying to organise support for Earth Hour - with a switch it off day - before the end of term...

Last week the weather was a little milder so the electric heating wouldn't have been working so much, also we generaly had fewer functions happening around school......things like this all help to save electicity.

Thank you for doing this amazing job!!

I think what would help a lot is if the IT department can do something little to the system:
When the computers are not in use, they simply switch to the sleep mode automatically.
I believe that the 'blue screen' would use up quite a lot of eletricity!
And also, although there is a small improvement, some classrooms' computers are never turned off.. e.g. the new classroom near the sixth form house!!
Is there anything we can do more to save more??

We will have to ask IT when we are back in school next week - but in terms of classrooms we probably need to ask the main users of a particular room to ensure they shut down?!
