[bikeqld] Re: [Cmass-Sydney] FW: Notice of Meeting: E-Bike legislation

[Ben Guymer]

I'd just like to point out how ridiculous any arguments about sourcing 
energy for e-bikes are.
Regardless of electric motor power, the energy is stored in batteries. 
Batteries are generally in the order of 200Wh, = 720kJ, = boiling ~2litres 
of water in a Jug.
If you have issues about charging an electric bike, save yourself by 
skipping your morning cuppa, have a glass of water instead, and don't eat 
meat.
However I also believe the particulate pollution from small 2 strokes is 
terribly wasteful - even the worst electricity generation practice will be 
thousands of times less polluting.

For more information about electricity distribution:
The electrical loss I believe is generally separated as Distribution loss 
factor transmission loss factor (DLF and TLF)
Together , the TLF and DLF add to give the total loss.  The combined 
efficiency is  roughly 90-94%

Some further info and links (courtesy Geoff Walker):

DLF (Energex) for LV (415/240V) line connected customers = 1.0786 in
2008/09.

TLF will be hard to find (powerlink?)

As for GHG emissions:

from the National Greenhouse Accounts (NGA) Factors
http://www.climatechange.gov.au/workbook/index.html

>From table 5 of the workbook-feb2008.pdf:

Scope 2 GHG Emission Factor (QLD) - from fuel combustion at power stations
associated with purchased electricity from the grid
 = 0.91 kg CO2-e / kWh

Scope 3 GHG Emission Factor (QLD) - emissions from the extraction,
production and transport of fuels for above, and emissions associated with
electricity transmission and distribution losses
 = 0.13 kg CO2-e / kWh

Total GHG Emission Factor (QLD) - sum of scope 2 and scope 3
 = 1.04 kg CO2-e / kWh
