Imagine a balloon filled with carbon dioxide. Now each time you
use electricity, imagine balloons of CO_{2} coming out of
the power station chimney. Each time you ride in a bus or car imagine
balloons coming out of the exhaust pipe. Just how much carbon dioxide
do you think you are making? Here are some of our estimates:
Using a 100W light bulb for 1 hour...................................7
balloons
Using a 2kW hair dryer for 15 minutes..........................35
balloons
Using 1kWhr (one unit) of electricity..............................70
balloons
Using 1kWhr of natural gas.............................................31
balloons
Travelling one mile by bus...............................................17
balloons
Travelling one mile by car................................................60
balloons
Using one litre of petrol (gasoline)...............................372
balloons
Try using the CO_{2 }calculator below to calculate
how many KILOGRAMS of carbon dioxide you produce in a day,
a month or a year.
Follow these instructions:

Enter a figure in the left hand column.

Hit the TAB key on the keyboard to move to the next cell in
the left hand column. Alternatively click into the next desired
cell.

The amount of CO_{2} in kilograms will be calculated
in the right hand column.
 To work out the number of balloons of CO_{2 }
multiply by 150.
