What would be the CO2 output of a coal fired power station (what we have a majority of here in Oz) in relation to charging hundreds of thousands of electric cars during the day while commuters are at work and again when they get home? Serious question, thinking about the future.

That is a valid question and I have no idea of the stats, but the real point is that something has to change, and a mass switch to EVs would be an important part of that change. With it would go gradual improvements in generation technology, so dependence on coal and other fossil fuels would gradually cease. Australia has a fantastic solar resource once there is a will to tap it.

Exactly, but the Govt are turning away from it. We have some wind power in SA, and they have shut down the coal plant, but they're importing power from Vic, which is 90% coal fired!!!

Even the subsidies and buy-back of personal solar has been dumped or cut (from $0.36 to $0.06), so there's no incentive to even do that any more, and I really really want to, but not at $6k to get a small system.

It's weird that governments aid generators in blocking solar uptake.....when going solar wherever possible makes a huge amount of sense from every OTHER angle.

For example....had most homes in Christchurch had some solar capability, the disruption from the second major earthquake would have been much less. Lights would have been on at the very least in all homes but the most damaged.

Totally OT, but after our latest storm last week, South Australian power was wholesale at $13,000 per megawatt, where Vic was $90... Well, Vic is selling it to SA for $12,990...

I predict a deep dark future.

@Linuxluver The feed in tariff is now 6.8c but if you feed too much, they'll cut you off. It's a rort. And I'm unhappy as F.

Edit: The reason SA was down was it was too windy for the wind farms... We. Are. Effed...

If all of NZ drove at the correct speed and turns lights off when we weren't using them and even turned off the LED lights on network switches it wouldn't make a dent on the worlds C02 emissions.

The planet will recover itself even after humans have wiped themselves out. Nature has an impressive way of adapting and repairing itself.

If everyone stopped now, it will take 50 years for the weather to recover. Thats assuming we arent already past the tipping point, which means the new warmed earth will run away, feeding of the environment we have created.

Back on topic, drag squares with speed. Run at 60k and your vehicle will push through the air, drag, wind resistance. Run at 120k, same fuel, same gearing, but the drag will be four fold for the two fold speed increase. My cars meter runs very low, even at 50k, in 4th, not 5th

I've noticed in driving my LEAF that my estimated range can remain stubbornly around the 160km mark even when my battery is into the 70% range.....provided I'm driving about 50-60kph on gently rolling or flat terrain.

I wonder how far I would get driving at 50-60kph on a flat road in Canterbury with no headwind. It looks like well over the 160km. In theory my LEAF can do 212km in perfect conditions on it's 24kw battery pack.

rendezvous: Is the additional CO emissions per km travelled, or per hour driving? I assume it's per km travelled. If it's per hour of driving, then you have to factor in the reduced amount of time spent on the road as you reach your destination faster.

Saving 10% of time doesn't justify 50% more emissions to any rational person.

Anyway.....this post was intended to inform people who share a concern about CO2 emissions. I understand some people aren't yet ready to be concerned about this.

To reduce emissions

- discourage anything that involves travel - tourism, import, export, factories ... ?

Any graphs for those activities compared to modern cars?
