Will New Zealanders really care about this EV subsidy?

Talkback host Ryan Bridge suggests otherwise, arguing that “Kiwis don’t care about climate change.

They say they do, but then they go buy a new SUV and have another child.

They have choices already and they’ve voted big, loud, and gassy” 

 

He’s rather cynical about the policy, saying

"Farmer Bob from central Otago with his Ford Ranger will be hit with a $3000 tax,

while latte-sipping, lentil-eating Fabio from Ponsonby with his VW Golf Electric will get an $8000 discount.”

 

Climate change tax proposed for driving utes, SUVs.

 

And today’s Listener editorial on the topic adds to this, saying

“there is in this policy a whiff of pandering to urban liberals at the expense of workers in the provinces.”

What you and I do about climate change here in NZ has very little to do with saving the planet.

 

Until the big Industrial giants stop the pollution and we stop buying/supporting them we are pushing change up hill.

 

How do get your vessel?? cycle or public transport?? if on a mooring do you outboard or row??

We want change but we also want to enjoy our pastimes without being hindered  trying not to leave carbon foot prints.

In EU I take an electric train (nuclear powered) to get to the boat followed by a brisk walk. I can row the deflatable but the solar charged electric trolling outboard is easier and lasts +6h.

In NZ I walk to the boat and wade to it or paddle a kayak.

True, my new boat used products of the petro- and other chemical industries in its construction, but it weighs a third-to-half of what comparable sized vessels weigh so consumed fewer resources.
There’s bugger all wood in it, too, so fewer carbon sequestering trees were felled for its manufacture. The wood that is in it was processed by one of the most efficient techniques for wood processing - peeling logs into veneers reduces sawdust waste.

I’d also be happy to go sailing in a dugout with outrigger and a woven flax sail.

Countries like NZ who prodoce less than 1% of the pollution globally when added together produce around 30%. So just maybe we should do something.

The alternative view if you are interested.

So, are battery electric vehicles better for the environment than internal combustion vehicles? Yes, they are.

 

 

 

 

Disagree.

 

No they are not if a nuclear power plant is built to provide the electricity. NZ at the moment is boarder line in the middle of winter if a sever cold number of days nation wide pushes to temp to zero Degrees or below for 48 or more continuous hours. Remember the time not to long ago electricity during winter was rationed and the spot price jumped and some peoples power account advanced to $1000 - $1200 per month, WATER HEATERS WERE ON TRIP SWITCHES AND ONLY ON FOR NON PEAK HOURS. Since then how many new houses have been built and with the promised 100,000 new homes in ten years kiwi BUILT PLUS THE NEW HOMES THAT WILL BE BUILT BY THE IMMIGRANT WORKERS WITH THE REQUIRED CASH / FUNDS. As I stated before one EU country has put a holt on switching to electric as they do not have the electricity capacity to cope.

 

NZ needs to, if electricity cars are to continue to amend the legislation that labour put in place preventing any hydro electric dams being built anywhere in NZ ON OUR RIVERS  in order FOR a couple of dams TO be built. NZ should have [ The Nats Bill English ] should not have given in to the aussie smelter Company  at bluff when they the NZ Gov't wanted to increase the price. They said they would close the smelter rather than pay a increase which was renewed at no increase. Bill English stated they would not get away with it a second time. The dam is NZ's biggest dam and they take nearly 90% of the generated electricity at approx. 4 cents when business and private house holds pay approx. 33 cents now. At the time it was close to election year and 400 jobs became the dominating factor [ BILL ENGLISH ELECTORATE WAS IT NOT? ], which with supply jobs, service, freight etc put it, the job numbers at around 3000 odd WOULD BE LOST . It would have been cheaper to retrain them, upskill them, transfer them to other parts of nz all expenses paid and close the smelter. NZ did not pay for the smelter. ELECTRIC CARS WERE INCOMMING, BEING MANUFACTURED, WARNINGS RE EMMISSIONS REDUCTIONS, GLOBAL WARMING, with ALL THE DISBELIEVERS, BUT LIKE THE CARLESS DAYS THAT WAS IMPOSED,  NZ DOES NOT DO ANYTHING UNTILL A CRISIS HAPPENS.

 

A NUKE ELECTICITY POWER PLANT IS STILL ON THE nats  MANUFESTO TABLE. IS THE LABOUR GOV'T LIKEWISE GENERATING A SITUATION THAT WHEN THERE IS HEPS OF ELECTRIC CARS AND INSUFFICENT ELECTRICITY THEY SAY TO NZ'S THERE IS NO ALTERNATIVE BUT A NUKE POWER GENERATION PLANT. NZ'S ARN'T GOING TO SAY NO ARE THEY AND THE GOV'T PROBABLY WOULD NOT BE ABLE AFFORD A BUY BACK SCHEEME LIKE THE GUNS.

Yes with V2G (vehicle to grid) as they are planning for Piha the electricity distribution network won't need to be boosted much.

Might even be better in local areas.

NZ just not having enough electricity generation is another issue.
