Many of the sources and ideas Ludlow quotes / promotes have come from vested interests, including CSIRO, entitles that are making a living off grants for advanced manufacturing R&D including renewables. For example, there is a CSIRO site right here in Melbourne that houses Printable Solar PV R&D, Advanced Manufacturing, Hydrogen Economies and Carbon Capture and Sequestration, almost under the one roof! You can walk 100m and get a diametrically opposed opinion, which one you or the media choose is arbitrary.* In many many cases they compete for the same grant money!

I worked in / with the same industry for over a decade, they lost me when after years working on low CO2 alternatives they started kyboshing pretty anything that competed for grant money, no matter how effective, viable or achievable it might be, the green energy industry is not as altruistic as many think.

*The truth is there is no one best, cheapest, greenest solution, and the field of renewable energy is as full of profiteers as any other including oil, coal, gas, nuclear, etc., etc.. Claiming one is better than the other is a bit like preferring a Gulag over a Stalag.

The fastest solution is a broad mix of all technologies, technologies that are based on actual immediately achievable and attainable results/actions and not promises at the end of a rainbow. The rainbow stuff has it's place, but it's not going to happen in the timeframe needed.

At the moment, the funding models lead to paralysis by indecision, they debate and debate and debate, too gutless to make a choice, it's like a punters lament scared to lose a bet, but it's not black and white like the media make out, the black and white opinions are a subjective choice not an objective analysis. They should be pushing forward on every available avenue and chipping away at the problem as much as possible on all fronts, it's not the all in winner takes all option that commerce wants!

Most of the electrical overhead equipment and transmission lines are a antiquated hybrid mess.
I used to be involved in the project maintenance of this equipment and there were never enough resources to fix it properly and we were always bandaiding solutions. It's needs a rebuild to service a nuclear grid and the only way that will happen is with overseas private investment with people like Cannon Brookes and the Chinese stumping up the money and building the reactors.

Very true, and this argument is universal, whether your power comes from large Solar PV farms with commercial grade 24x7 battery storage, coal, gas, wind or nuclear.

Extremists claim micro-grids are the solution, but they are still grids that somebody has to own, operate and maintain.

This highlights the very problem I'm discussing, the analysis of energy sources is completely subjective, and the outcome of any report is based on arbitrary selection of the metrics used in reporting.

The more inclusive you make the measures, the less difference there really is in terms of cost and environmental impact. For example, just because Solar PV doesn't make a mess in your own backyard, at least not at first until you have to dispose of redundant panels, doesn't mean it is not filthy and harmful on a global scale. The atmosphere is a closed system, just like fresh air the filth doesn't stop at the customs and quarantine border, it's not stopped by border control!

What is more, the total risk profiles over a long period are quite similar, just each has it's own strengths and weaknesses, in other words differences.

Even the A-Grade standard for future clean energy, fusion, has it's risks and issues when fully accounted for, there is no solution that offers a free lunch.

There is some significant irony in people arguing against nuclear because of the issues of dealing with hazardous waste, only to claim batteries are a solution to 24x7 power from Solar PV and Wind!   ------------ Don't mention the war!

The current cleanest Solar PV technology is printable solar, but it's energy performance is poor relative to silicon or perovskite alternatives, you need one or two orders of magnitude more panels by area to deliver the same energy. Let's be clear, that is 10x to 100x the area for energy equivalence.

Silicon, perovskite and telluride based panels are all constructed using rather nasty trace elements. lead, arsenic, cadmium, cyanide, and processing the waste from silicon or perovskite panels is banned in some locations for the same reasons that workers have to be protected form silicate dusts in the mining or construction industries. The old panels are classified as a toxic waste.

Even printable solar is a problem, they are trying to massively improve the efficiency by, ............. adding perovskites loaded with lead compounds! This stuff can have more lead in it than is actually legal in some locations to sell as paint, if you sold paint with it in it you would be charged, fined and possibly jailed by the environmental protection agencies in some regions! They proponents argue that it is safe because it's a solid, but so was the stuff that now slowly leeches poison out of landfills.

Batteries are even worse!

Until the various industry segments own up to all these issues, in other words act honestly, we aren't really making progress we are just shifting the problems around in time and location.

@Lods don't get me wrong, I want these solutions to work, I still work in the advanced manufacturing industry, as much as I want it to work I can see the folly of choosing solutions built on false claims.

For example, at the moment I'm working on membrane technologies, not the membranes themselves but how to make holes in them. We can use lasers to drills tiny geometrically spaced holes in special membranes. Nanometre sized holes space just microns apart. But to be commercially useful you need ways to make this stuff by the square kilometre, at the moment the fastest we can go is about 2.5 Million holes per second, and that sounds like quite a lot. But when you are talking about nanometre sized holes spaced micrometres apart it's only at best a few square millimetres per second! That's at least two or three orders of magnitude away from being useful for industry. Yet there are people out there now selling this technology to politicians as the solution to energy storage or generation.

I did the sums the other day, if I can go at 2.5M x 50nm holes per second, at 1um spacing, that is 111hrs to make a 1m² sheet. I can add some more lasers, let's say 1m² / hr is needed so just use 111 lasers. The laser I use is worth US$1.3M a piece!

Nuclear power plants are way more expensive than alternatives and require very long lead times.  We’ve missed the boat on conventional nuclear power by several decades.

I recently watched a fascinating documentary on one of Scotland’s nuclear power plants.  Apart from the technology and environmental requirements, the youth of the highly qualified technicians was surprising.

Part of the conversation was about the inevitable de-commissioning of the power station.  The head honcho explained that no more power stations using that nuclear technology would be built in the UK.  It wasn’t clear what would replace them; perhaps smaller plants.

I also saw a documentary that briefly looked at the last “coal-fired” power station in the UK.  It burns sustainably harvested timber by-products 🤔

Way more expensive to set up, but once running they are bang for buck in terms of gigawatt procured vs uranium required vs waste created.

I chose the word efficient for a reason.  Watching Australia roll out solar technology over the last 20 years doesn't make me say that its quick to produce nor cheap, and I don't see us having an abundance of redundant energy that we are storing (quite the opposite seems to occur frequently).  People seem hung up on the waste component of this.  Things aren't static.  The waste isn't what it used to be, and im sure that there are technology advancements that could be done to reduce the waste further by recycling it somehow.

For those old enough to remember....which on this site, is probably everybody, think back to the old VHS vs Beta days for video tapes.

A battle of technologies that ultimately did the same thing, albeit to differing degrees.

In the end, VHS won out.
In reality, Beta was the far superior product.

VHS had better marketing, so despite being inferior, won over the public.

BETA is Nuclear.

Re-educate the public and get a better marketing strategy that can cut through the alternative spin-doctoring and mud slinging of the alternatives.

The economic analyses are unequivocal, nuclear power generation is now too expensive.  That’s why the private sector won’t invest in nuclear power and is cutting its losses by cancelling power stations under construction.

There may be issues with the economic analyses but the corporate bean counters are convinced.  The only new nuclear power plants will be underwritten by governments.  As EB pointed out, most governments will struggle to find the funds, or private sector partners, to get the power distribution networks up to scratch.

the same applies to renewables about the grid and storage of energy. 

Its still moving forward.

  Im not arguing right vs wrong here, I'm saying the bean counters don't always measure things with saving the most amount beans, rather they count beans with politics involved, and will waste more beans for many reasons not to do with being efficient with the beans.

We all know that a nuclear power plant is unwanted on anyone's doorstep and thats the main blocker behind any of them being built and consequently a political loser which is the main blocker behind them being built.

That's the folly, it's the same folly for most human technologies, phones, batteries, plastic bags, paper, cars, tyres, and now Solar PV panels.

Paper and plastic are way easier to recycle and re-use than any of the other alternatives like Solar PV panels or batteries, and we have paper and plastic piling up in repositories all over each and every major city, even warehouses full of the stuff to keep it dry so it won't spontaneously ignite, or else the eventually bury it after residents have diligently sorted the recycling into clean piles and / or been fined for throwing it in the wrong bins! Do you know the biggest potential use for the bulk of it, they are planning to combust it in specially designed furnaces to make energy!
