Heres the thing PhillipA, I don't give a flying **** where my electricity comes from . Solar Wind Coal Hydro , I simply don't care because its what it is & theres nothing I can do about it . No good rabbiting on or getting stressed over it. I plug the ****ing car in & it charges . Thats all that matters.
I have solar panels , my feed in tariff is 0.71c , thats how much AGL pay me for a kwh of electricity,
I buy back power for 0.29c kwh
My car uses 30kwh for 100km You do the maths.
So why make a point of your "green" credentials by paying extra for non existent green electricity?
So you can boast about it? You made the point , I didn't.
Regards Philip A

Hell a mate got a 6kw system put in back then and gets a $1000 a 1/4 from it.
now its 10c feed in with 15c buy back for off peak and 25c peak (these can change a few cents depending on location) so while you can run a car for nothing the fresh lot coming in it will cost them, yes less then petrol if they use it like a regular town car.
rammypluge with electricity unless live near a hydro plant its doesn't matter what you buy on paper your still being supplied the same stuff everyone else gets your just paying more for what is cheaper to produce electricity, and i also said oversea's this changes due to higher rates of renewable electricity.

Do you know how accounting works? You put units into a common pool, then take some units out later. They won't be the same marked units of course. Accounting isn't like carrying around a bag of metal tokens, where every token is individually marked for a single use.Quote:

It matters not that the units you're buying are produced from coal at that instant, what matters is that at some other time green units were used instead of coal units. Simple, eh?
Even 'clean green' Tasmania - supposedly 100% hydro power - ran out of power / dam water a little while back, because they sold too much power to Victoria! Tasmania needed to bring in massive diesel generators until the dams filled back up!!
If a person pays for 100% greenpower they are ensuring x units of greenpower are produced (rather than x units of coalpower or whatever). If the person doesnt consume it directly themself, and sheesh who is going to try to track those specific electrons through the vast interconnected network, then they will be ensuring that joe blow, who was previously using non greenpower, will unbeknownst to him be consuming those x units of greenpower.
Quite true, bad accounting risks got them into debt. Mind you, the diesel gennies were needed because the extension cord to the mainland broke, so they were unable to ask the Victorians for some brown electrons back to replace the green ones they had sent north the year before. Over a longer period though, Tasmania still produces more hydroelectric energy than it consumes, making it 100% renewable on balance. If they ever build a second cable and add some wind farms to the west coast they could get to supply a significant chunk of Victoria and NSW grids too with green energy.Quote:

Er no. Retailers are compelled by law to buy all units of wind and solar power produced through the purchase of credits. If they do not buy the credits they have to pay a penalty to the government.Quote:

So all wind and solar energy produced has to be bought anyway by retailers. That is why coal stations are not fully utilized even though per kWH they are much cheaper than the wind power cost plus the credit.
When I first read the enabling legislation back in 2006?, I couldn't believe that wind power companies had no obligation to supply power 24/7 by buying coal/gas/hydro power to supply when they could not. So AEMO was then formed to control the network. Crazy stuff.

So $8.70 for 100km?Quote:
