Blackouts and Brownout are possible this year, what will happen when more EV's are being used.

More generation?

How long is that going to take 20 - 50 years?

In the process of getting 16 panels installed this month, neighbour has just had similar installation completed, 42.4c /kWh here in Northland!

In our case a few weeks hopefully. We've got 5kW of solar in the process of being installed. No storage planned in our installation but at least we're taking ownership of a good portion of our consumption including EV charging.
And for those bleating about EVs I trust you've turned your spa pools off by now.

Depends if Tiwai actually closes at the end of 2024? If so, there'll be more electricity produced than we can actually use, so some of the grubbier ones will be shutdown.

The R-- tards are also pumping out news that they will make your lpg in to hidrogen. I guess they never did hear of hydrogen explotions. You really wonder if they have 1 single brain cell. yea you really want hydrogen to cook with instead of the saver LPG we already have. https://en.wikipedia.org/wiki/LZ_129_Hindenburg

I don't like hydrogen either, but bigger brains than yours are working on it, so don't let it worry you.

How about a wind turbine?

All right, I'll take it.

The (lifetime) costings on smaller (domestic) turbines aren't even close to those of PV. NZ's typically gusty wind conditions tend to destroy the mechanicals and very few locations have consistent wind run thereby meaning turbines spend a lot of time as ornaments. Even in a prime location they come close to payback about the same time major repairs are required. You're actually better off investing in a micro-hydro system if you have a stream with consistent flow handy.

What if the government puts in a wind turbine, like they do in Germany? I was there in about 2012 and they had loads.

hang on a mo Ill just recheck the backyard nope,cant see/hear any running water
Solar energy has to be the way forward. Looking out the window right now, hardly any houses have solar panels.
My brother (a licenced photo-voltaic installer) fitted panels to his partner's small house in the UK, and even in a UK February, there is some gain.
The problem in NZ will be the rip off power companies making sure that no matter how much or how little power you generate for yourself, they'll still be charging an arm and a leg to maintain their profits.
No doubt many will have seen the pic of the helicopter emptying a bucket of de-icer on just one frozen wind turbine.

I,ve done my sums several times and even if Electricity increases in cost by about 200% at least theres no benefit to me:my heirs and successors maybe.!

The key to maximising PV returns, and therefore ROI is to use (or store) your own generation. Storage can be as simple as diverting 'excess' generation to heat a HWC or charging an EV as by doing so you are offsetting consumption that would otherwise cost you full retail including GST so that is your effective return on that electricity.

Surely no more than any other power plant?

higher power prices with the excuse to try make people travel less to save power

No problem, burn more coal.

The fibreglass/carbon blades are an issue. They are truly massive things. I wonder if they could use pyrolysis to remove the resins and recycle the glass and carbon? If other forms of energy generation are an end-of-life issue then they need to be examined too. Although I suspect they would be mostly metals and concrete, all of which are recyclable.

Could just make them from aluminium, same as an aircraft. Construction is easy enough, just press out the frames and rivet the skin on. Pretty mature building technique. Aluminium can very easily be recycled.
However the blades may be able to re-used, just rebuild the generator unit.

I suspect stress fractures might be the reason why they don't use aluminium. Aircraft wings get regular inspections for this reason.
