Reminds me of the comedian, the late Mitch Hedberg, who said, "Pringles were going to make tennis balls, but when the delivery truck turned up, it was full of potatoes, so the boss said Let's cut'em up."

OK although I dont really participate in this forum anymore I do occasionally have a poke around.  I can't let this illogical statement go unchallenged.   It is true that an EV is only as clean as the source of power used to recharge its batteries. It is also true that the petrol we burn here in Australia has been brought here by a fuel-hungry tanker ship burning pretty dirty fuel.  Let's look at the rational facts.

 

Do EVs in Victoria rely on brown coal for charging? The first point is that your statement seems to indicate that you believe that all of Victoria's power comes from brown coal.   The fact is that 37.8% of Victoria's power comes from renewables.  The projected and achieved targets are: 

 

  • 25% by 2020 (achieved)
  • 40% by 2025
  • 65% by 2030 (previously 50%)
  • 95% by 2035 (new).

It should be understood that the trajectory is towards cleaner power; therefore, with every year that passes, these vehicles get cleaner, whereas petrol cars remain pretty much the same.  As of today the average EV is charged at least a third by cleaner electricity.  I personally pay a couple of cents per KWh for green power. Yes I am aware that the actual power I get comes from a pool of electricity but my retailer buys the amount of power from renewables that equals what I use.  I also generate twice as much power as I need.  I have done some calculations and I believe my rooftop panels could drive an EV for 14000KM per year.

 

I would suggest that an EV even when powered by the standard mix of power from the Victorian grid is still much cleaner than a car that's fuel is shipped in a tanker from abroad and refined (electricity hungry process) and then is put in a road fuel tanker and driven to the petrol station using more fossil fuels which by the way also come to this country in a tanker ship.

 

 

Why do you pay extra for green electricity. It is a well publicised fact by our energy minister that wind and solar are the cheapest form of energy.

I don't actually pay more per KWh but my power retailer sources its power from renewables. Of course, there are times when there are not enough renewables available (although this gets less with time) but in this case, the company buys an equal amount of renewables when it is available, which I am assuming is more expensive at these times.  My retailer charges 26 cents per kWh  My assumption is I could get this cheaper if I did not care about the source.   My retailer invests in renewable energy technology.  In any case my bills are extremely low anyway due to rooftop solar so I am happy to support renewables.

Sorry, I thought you said you pay a couple of extra cents. Still kinds of misleads the general public. I had a friend say the Adelaide City Council only uses renewable energy which is not right obviously to some of us but not to the non engineering background people. There is at least 2 gas turbines running continuously in Adelaide directed by AEMO for grid stability so ACC will be getting some of that. ACC purchase some of there energy from a solar farm near Streaky bay on the west coast of the state about 500 km away in a straight line so really they would not be using any of the energy from there. I feel it is misleading and hides how hard the renewable grid is going to be. It also does a dis-service to the rural towns who host these facilities. Does this mean they only use the fossil fueled part of the grid.  The ACT do the same thing but are close to the grid stabilising coal plants in NSW. When they say SA got 85% of there power from renewable, I wander if that is minus the stuff the ACT claim from the Hornesdale wind farm or is it double dipped. There is no Wind turbines even visible from Adelaide because it will ruin the view.

SA got batteries supplied by Musk on a no workey, no Pay basis.  Scotty from Marketing rubbished the idea. The  State Libs continued the battery policy and extended it. Why don't you mention batteries? It's very much a part of the equation.. Nev

Did you know that Australia is wider than the moon?

 

The distance from Byron Bay to Dirk Hartog Island is 3998 km, and the diameter of the moon is 3474 km.

Alright smarty. Give us the scientific stuff. 

The value given for the diameter of the moon is probably derived from a straight line measurement from one side of the Moon to another, through the centre of the sphere. The value for the distance across Australia is probably derived from the length of an arc of a Great Circle passing through both points. If a chord was drawn through the Earth's sphere between the two points, then the length of the chord would be less than the length of the arc.

 

Therefore the straight line distances, diameter -v- arc, would have Australia being narrower than the Moon.
