I've heard that $5 trillion argument before and it's like the guys that accuse big pharma of being able to make each tablet for 20 cents. They're ignoring the R&D costs. We'll the German government subsidies of the last few decades led to both innovation and economies of scale. Renewables are now 1/4 the cost of nuclear per unit to the grid. That doesn't include firming - but as I E shown from the Australian industrial group that doesn't matter. They Overbuild. So remember it's not just renewables replacing fossil fuels one to one, it's also electrification of everything HALVING the total energy they must replace! Get your superannuation out of fossil fuels ASAP as they're going to be left with a bunch of stranded assets

Peak oil is pretty obvious - but the head of the IEA actually says we'll hit peak DEMAND before we hit the peak of geological supply issues. Also, avoid Simon Michaux. He's a bit of a slippery fellow with data. He argues against renewable energy for the alt-right. Hits people new to alternative energy with such an avalanche of misinformation that they cannot see the forest for the trees.

EG: Simon Michaux’s whole argument rests on a straw-man - that renewables need a month of storage by the *fanciest* batteries to get through winter. This multiplies the minerals factors of hundreds to thousands. But “winter” is not the blind-spot Michaux pretends it is. Engineers have a plan.

OVERBUILD RENEWABLES TO REDUCE STORAGE! Renewables are now 1/4 the cost of nuclear – so we can Overbuild them. Build enough to sail through winter with each city having 2 days storage, and then you have excess “Super-Power” to do other work the rest of the year. I list a number of experts.

They say Australia can probably get away with a 200% renewable grid - that’s just for our electricity needs. For industrial transport, heating, mining, smelting and refining I reference an Australian industrial think-tank worth a THIRD of our Stock Market! They plan to Overbuild 2020’s electricity grid by 5 TIMES to produce all the products they want to sell and export.

Also, some energy experts don't even call it Overbuild - they just model how much will do the job and talk about extra powerlines. As this energy expert writes:

"Next Michaux overstates the requirement for batteries by at least an order of magnitude by ignoring a few things. First, he ignores the massive HVDC interconnects being built around the world that deflate grid storage requirements. HVDC is the new pipeline (and LNG tanker and oil tanker) after all."

USE PLAINER MATERIALS: all sectors of the energy transition are pivoting away from fancy rare earths and scarcer metals. Why? It’s the cost! Consider the plainer options. Solar is silicon (27% of the earth’s crust!) and aluminium (8%). Wind is aluminium and iron ore (5%) and fibreglass (glass fibres and recyclable plastic polymers.) Aluminium can replace copper in almost all copper's roles - yes even in EV's and it's 8%! 1200 TIMES more abundant than copper. It recycles well. We will never run out. https://www.shapesbyhydro.com/en/material-properties/how-we-can-substitute-aluminium-for-copper-in-the-green-transition/ Also, all the copper ever mined is still on earth (apart from a few satellites.) We can recycle and reprioritise that.

GRID BATTERIES can be made from sodium (sea salt) which is safer and 30% cheaper than lithium. Even if we DID need a month of storage (we don’t!) - Sodium could supply it a million times over.

This saves all our lithium for EV’s. They’re going LFP - Lithium Iron Phosphate. The USGS says there is 89 MILLION tons of lithium. At 6 kg per EV that’s 14 BILLION cars - we only 1.4 billion. Also - we keep finding lithium faster than we’re mining it. In Sept 2023 America just discovered the worlds’ single largest lithium reserves.

USE PHES! Pumped-Hydro Electricity Storage hardly uses any metal for the enormous energy stored. The best PHES sites are 400 to 800 metres. Michaux’s 1000 page “Report” said sites are too limited! But it had no source! Here it is. https://youtu.be/LBw2OVWdWIQ?t=1342 Are you ready? He tells us the WORLD doesn’t have enough pumped hydro sites because of a viability study about PHES in SINGAPORE! Pancake flat Singapore - their highest hill is only 15 metres? Gee - I wonder why THEY had trouble finding enough sites!? (Facepalm!) This is an example of how far outside his comfort zone he is working. When this was pointed out to him he replied that the amount of water that was required was an extra 50% of the annual fresh water we use. But it’s a once-off fill - and we’ll be doing it over 25 years. So even if the quantity is true it’s only an extra 2% per year over that period. THEN the top-up rate due to evaporation is only 10% of the water we CURRENTLY throw at cooling thermal stations like coal. We’ll end up saving water! https://theconversation.com/batteries-get-hyped-but-pumped-hydro-provides-the-vast-majority-of-long-term-energy-storage-essential-for-renewable-power-heres-how-it-works-174446

Instead watch Australia’s Professor Andrew Blakers who won the Queen Elizabeth Prize for Engineering (the Nobel prize for engineers). Here’s his global tour of pumped-hydro storage. http://youtu.be/_Lk3elu3zf4?t=986 The world has 100 TIMES the pumped hydro we need! https://re100.eng.anu.edu.au/global/

Michaux’s OWN PAPER shows we have MORE than enough minerals if we just subtract his ridiculous “Fancy batteries that ate the world”. Check “Michaux Sans Batteries”. https://eclipsenow.wordpress.com/michaux

Michaux is just a former peak oil doomer trying to justify his doomer manifesto. Avoid him.
