Interesting numbers

The following are some numbers that might help put the proposed Viking windfarm into perspective.

One pint: The amount of fuel sustainably saved during each revolution of a 3.6MW turbine.

13: The revolutions per minute of the new 3.6MW turbines.

27: The revolutions per minute of existing Burradale turbines.

72: The number of 20-tonne trucks that would unsustainably transport <i>every day of the year</i> the fuel required to produce the same power generated by the 127 turbine windfarm operating at 50 per cent (the average at the Burradale site is 52 per cent).

11,200: The litres of fuel sustainably saved on average every day of the year by one 3.6MW turbine operating at 50 per cent.

11.7 million: The tonnage of fuel that could be sustainably left in the ground during the 25-year life of the windfarm project if it goes ahead.
