Nuclear as far as climate is concerned should as its low co2 but its not renewable as such.

Bring on the fast breeders?

We don't need nuclear in NZ. I guess longer term the jury is out on whether climate change will ultimately deliver more or less rainfall into the hydro dams - I think the last study I saw predicted marginally more - but as long as we have plenty of hydro plus storage for wind & solar it's just not necessary here.

Other places though ... Australia should be doing it.

We will certainly need to do something to supply all the extra electricity going forward.

"A pellet of nuclear fuel weighs approximately 0.1 ounce (6 grams). However, that single pellet yields the amount of energy equivalent to that generated by a ton of coal, 120 gallons of oil or 17,000 cubic feet of natural gas, making nuclear fuel much more efficient than fossil fuels.

In addition, nuclear power plants operate more reliably than other power generation facilities. In 2017, nuclear plants worked at full capacity 92% of the time. For comparison, consider the operating times for other energy-generating sources: coal plants (54%), natural gas plants (55%), wind generators (37%) and solar plants (27%)." Sciencing.com

We (NZ) wont, we have plenty of consented renewables, plenty of space and capacity to install wind and solar, and grid storage is a thing.

Australia has well plenty of solar, and space, they are busy prepping to build a massive solar array to power Singapore for one, Australia could easily supply the worlds energy demands via solar (though not very practical)

Countries like Uk , USA, Japan and Germany etc may be best suited to fusion baseload

This is an example of "Perfect being the enemy of the Good" in that he doesn't believe we can walk and chew gum at the same time...

I think it is worse than that.

Here we import petrol, which had to be transported from (overseas) refineries, which used crude oil that had to be extracted from the ground and transported to the refineries. Burning petrol & diesel causes more CO2 emissions than just th4e stuff coming out of the tailpipe and in a country like NZ that sources its petrol & diesel from overseas the CO2 emissions are even higher than in many countries.

Then there is the idea that batteries need to be improved - the reason that hundreds of billions of dollars are currently being spend on R&D for new batteries is BECAUSE electric cars are big business. If we don't adopt BEVs now then there won't be the same investment in future batteries.

He doesn't tell people that they shouldn't have refrigerators now due to them being powered by coal, why is it that EVs are being singled out? Instead of pushing this idea of not going to EVs today, why not push the idea of making our electricity production greener and making that happen sooner rather than later?

Nuclear is the most expensive generation in terms of LCOE, construction has a very long lead in time (especially with NZ's RMA, etc) and have significant safety and security concerns bot in terms of NZ's seismic activity and our remote location for transportation of waste material.

The real discussion here should not so much be the percentage of renewables in our electricity generation so much as the percentage of our energy consumption of fossil fuels. (Select data for NZ). The electrification of our vehicle fleet will offset the import of oil with significant advantages in our CO2 emissions, so long as the extra electricity generation can be done without resorting to thermal power stations.

Almost a half of all global commercial shipping is oil, go onto a ship tracking site and see how many ships that is. Its insane.

Ooh hello...

Except its accompanied by some brain dead currency conversions by reporters,

"The Atto 3 currently retails in Australia for AU$44,990 (NZ$50,125) drive away, which could potentially see it dethroning the MG ZS EV as New Zealand’s cheapest EV if Ateco can achieve similar pricing here."

Err last time I looked our GST was 15% while OZ was 10% so you need to add another 5% on that price taking it to over $52K ( the MG is $49.9K)

I would be surprised if the smaller battery Atto 3 launched for more than the MG but who knows.

yeah I am not a proponent of Nuclear as it currently stands, esp not for NZ, purely for these reasons, too expensive, too slow.

So far as 'battery' capacity is concerned this article in Stuff recently explained the rational behind the Lake Onslow pumped hydro proposal well.

ETA: and compared to a nuclear solution it probably stacks up better in terms of cost and with less potential pushback from the public.

Lake Onslow is a boondoggle and a glint in a Academics eye... The costings are 15 years out of date, and if you were going to spend $4 billion (it will be more) on an energy project in NZ. doing it in the middle if the South Island when most of your load and people live in the North seems odd..

Simply building more renewable generation in the NI is the optimal solution, this allows the existing Hydro to be run less and retain the water we already have..

Best (cheapest) solutions I have seen is build 2-3x your requirement in wind/solar + 24-48 hours of grid storage (this actually from Tony Seba) , this was for USA though and we already have a lot of hydro and geo which should reduce our need for a lot of that
