Pupils learn better in natural daylight!
We have continued our campaign to persuade teachers and pupils to turn off the lights when they are not in the room or there is enough daylight to use that. Government surveys have shown that pupils learn better in natural daylight than they do in artificial flourescent lighting.
Electricity usage by the school
We have continued to log the electricity usage of the school as shown here. It has been useful to identify trends in the data. 2006 has been the year in which we have used the most electricity and we have been looking into reasons why that may be.
We have recently had a Smartmeter installed which will allow us to access this data on-line in real-time rather than looking at bills when they come in and this will allow us to pinpoint times when electricity use is at its peak and why.
Gas usage by the school
We have continued to log the gas usage of the school as shown here based on data supplied by bills. The dataset has not been particularly reliable due to incomplete records and data which we hope will be addressed soon.
Energy saving lightbulbs
The Footprint Trust ran a stall at the Christmas Fayre to promote the work they do on the Island. They gave out free energy saving light bulbs to those who wanted them in order to publicise the fact that if we all swapped one normal bulb for an energy saving bulb then we could close one of our power stations down.
They gave out 45 light bulbs on the night which equates to 45 tonnes of carbon saved over their lifetime. This is based on the following calculation:
A 100 Watt bulb burning for an average 7 hours per day for 365 days per year uses over 250kW hours per year and produces 125 kilos of carbon.
A low energy bulb uses only 20% of that producing 25 kilos of carbon per year saving 100 kilos of carbon per year or 1 tonne over its 10 year life span!
