A few of us on the eco-team have been doing some cerebral fitness and tried to workout how much evergy we can off-set when we light the tower. I thought it would be good if you joined in too. Do help out with the maths and suggestions.
We've been told the tower will use 90kWh of power when it is lit (did you see it this evening?). If it is lit for an average of 8 hours a day 365 days a year then it uses 253 kWh (90x8x365)
The sanctuary has 52 bulbs and are on at least 2 hours a week thus using low energy bulbs would save us something like 650 kWh (Instead of 150W bulbs we use now, we could us 30W energy efficient bulbs which would give us the same brightness)
So we've already reduced the carbon footprint by quite a bit more than 2 times (is that right)?
If we get 50 folk to change one high use bulb like living room or hall or kitchen with an energy efficient one and imagine it is lit 365 hours a year (1 hour a day which is possibly quite conservative) then that's something like a saving of 900kWh which means that's reducing the energy footprint by a further 4 times. Correct?
If all that is true then by what percentage or proportion are we reducing our energy use?
Bet you never realised Christianity could be so exciting.
