In the interim however, it does mean that the world's coal use is going up That will go down too eventually too. Only around 40% of our steel is made from recycled steel which is a fair amount, but we'll need a hell of a lot more steel because that's what we need for renewables Currently, steel is made from coking coal. The alternative is hydrogen but that's not yet scalable, and realistically that hydrogen will likely be made from gas rather than renewables. Making hydrogen from renewable electrics is just making electricity with extra steps. But hey, at least polluting hydrogen is still better than coking coal so there's a. silver lining

The laws of thermodynamics are very clear on why in a closed system, such as earth, it is a monumentally stupid and catastrophic idea to create machines to clean up the mess you make with the machine you use to create them unless you've managed to break the laws of physics by creating 100% efficiency... not gonna happen.

They need to get Ford and others to start building batteries and electric cars in Australia! Australia needs the tax incentives that we have in America, so that Ford will invest in a battery plant in Australia. Otherwise Ford will say "We can import batteries to Australia once we have enough made in America to produce all the cars we need in America. And that will take until about 2035. I would love to stop importing oil to America, and especially to places like a small village on the coast of Alaska, that must barge in millions of gallons of oil to provide heating and electricity to that small village each winter. They have started to install a couple of small wind turbines, about 1 MW each, or less, to provide electrical power to the village. They sometimes will fly in a jet, to drain the excess fuel into the storage tanks to get them through until the spring thaw, when a million gallon barge of fuel can fill the tanks again. For Japan, Singapore, and many other areas, they need to stop importing oil so they can stop exporting so much money they exchange for that oil. I think it would be wonderful to replace some of Japan oil fired power plants with geothermal. They might not need to drill down 1,000 feet to reach some 1,000F heat in the rocks! Install a 8" diameter steel pipe, with a 1" diameter injection water line going down the center, to supply water, that can turn to steam, and then run the power plant on the surface. The total cost of ownership is much less with a EV than a gas car. I like to compare it to the coal fired locomotives to the diesel electric locomotives they started using in the 30's in America. By 1948, they started to shift to diesel locomotives, and by 1950, every rail line went to diesel. It still took them 10 years to fully convert, and by 1960, it was rare to see a coal locomotive, and by 1965, there where only a handful still running a steam locomotives, mostly for excursion lines, and not for profit main lines. Australia will really miss the boat if they do not have incentives to the auto companies to build the battery in Australia and to build the electric cars there, even for export to other countries.

The EV battery is limited to when the EV is at the home for two reasons. (Assuming the EV is used for its primary purpose and the home has Solar) . 1) The EV will often if not always be away from the home during the peak solar generation period, which means the solar will at least in part be "offered" to the grid utility. When the practice becomes widespread it's highly likely the "home solar" will simply be used to charge a *utility battery* (!) and there's a reasonable chance of oversupply from homes meaning that utility will not want the energy (if their battery network is full) . 2) Unless you can guarantee power cuts will only occur at certain times, essentially when the owner is at home, the vehicle provides zero cover. Imagine you're about to leave for work and there's a power cut? What are your choices? Stay home and explain to your boss you won't be in for the third time that month? Leave and use public transport (in which case, why do you own the car?) Leave in the car and hope the power returns? You mention "grid independence for a couple of days".... *Only if the car is there* (see above) . Solar with a home battery solves the problem and pays for the system. You remove the home from the grid, and sell excess when you want to.

I used to live in Germany near Hannover and driving along some of the autobahns you could see a history of wind turbine development. Early examples had towers more akin to the ones holding the cables for the national grid rather than solid structures and were much shorter. At my house near Celle I could see over 20 turbines and that wasn't unusual. Driving along the 7 down towards Munich the amount of solar panels covering farm buildings was also staggering.

One aspect missing from the narrative in this episode is the fact that the resources needed to mine, refine and manufacture every wind turbine remain heavily dependent on fossil fuels. The steel needed for the mineral mining machinery, the energy used in mineral refining and final production of the resources needed for renewable energy generation and storage all depend on fossil fuels. We have a long way to go before all renewable energy production and storage is fully decoupled from fossil fuels. I look forward to the transition however, we must remain aware of the fact that every solar panel, every wind turbine and every EV requires a significant amount of fossil fuels to get from raw material to finished product.

Mr Lewellyn, kudos to your interviewing skills, appreciate.

The amount of material required to build a sufficiently strong engineering structure increaces non-proportionately with the size not only because the volume increaces at a greater rate than the linear dimension but because a larger structure even of an identical geometry to a smaller one requires more strength to resist forces that deform it. Because of this there are ultimate practical limits upon size. Consider the case of the space elevator cable which even if scaled up in all dimensions would be incapable of resisting the tensile forces resulting from it's weight. The only way to make such structures bigger is to use stronger materials. Windmills a mile high? But made from Graphene rather than Carbon Fiber!

Very good video as always. I'm way behind and only just getting solar installed, but hoping to make a bit of a difference. On subject of renewables, would it be possible to promote a link for a wind farm off of the Dorset coast? There's an online petition running to revisit an idea of a wind farm off of Poole / Bournemouth. Dorset is massively lagging behind with wind turbines compared to the rest of the UK and would be good to see us contributing to the grid as well.

Utilities here in the US are obligated to eventually support demand response due to FERC 2222, but not all these energy markets exist yet. This works when billing systems exist to support aggregators who can organize VPP's (virtual power plants), energy trading, and time of use pricing, with a fair price for scheduling load or for exporting power from batteries or EV's when the grid needs it.

Yes they are profiteering a lot, but not exactly for the reason kokofan says. It's also to do with the way energy is charged. It is currently based on the wholesale price of the highest resource cost of electricity generation for covering the network in peak times, that being currently gas, so all these "cheap" renewable energy suppliers reap the benefit of HUGELY inflated prices. This is something that needs to change as a matter of urgency as I have no interest whatsoever in renewable energy if cost to the customer is still based on the costliest "fuel" price used to generate electricity elsewhere & not the actual source of the energy used across the board. In my opinion, if a supplier says they only use 100% renewable energy then they should be mandated to charge you ONLY for the cost of that renewable energy - not what the cost of gas is, as last I heard was gas wasn't renewable.

We have a wind turbine from 1987 which is still operating (I think) at Breamlea in Victoria, and the Toora Windfarm in South Gippsland has some turbines that have been operating since about the early-'90s.

IMO, Too much on 'the positives' without addressing the negatives that come with the positives. Ex. at around 37 minutes, Robert speaks about decreasing usage of power at times when less energy is produced. OK, quite sensible, but that would also greatly increase the usage in a smaller time frame - which is also the time frame that industry is using the most power. Can the Grids handle that? Additionally, I heard no mention of dangers to wildlife. Birds are smashed by wind turbines and fried by solar. Considering the increased units of these sources, there would also be an increase in wildlife deaths/injuries. What about waste? Parts for Green energy don't last forever and are surely not made of biodegradable materials. Just a sample.

I've not watched the video yet, but just reading the video title. And, well, the fact that 100% renewable energy is inevitable is right there in the very name "renewables" itself. Renewables renew. They don't run out. Whereas, non-renewables don't renew. They run out. And, eventually, the things that can run out will run out, while the things that can't run out, don't. And, basically, one day, all that's left remaining are the renewables. In that sense, it's only an illusion to imagine that any of us have a choice in the long term. You can love oil and coal and gas all you like, but eventually it'll all run out and you just won't have those options anymore. Because when you burn those fuels, they're gone for good. And, by all estimates, we've only got a few decades left for oil. Natural gas won't be far behind, and coal might reach a century. But the thing with those estimates is that they are "at current usage rates" and our usage rates historically keep going up. So they're drawing a line on the graph to guess at the "death date" for these fuels, whereas it will, in reality, be a curve. But the big one is that, well, imagine that there's only a single barrel of oil left on the entire planet. How much do you think it would cost to buy the last remaining barrel of oil in existence? Truth is, it's priceless. As Indiana Jones would rightly say: "It belongs in a museum" and it'd be almost blasphemous for someone to buy that and burn it. So what I'm getting at is that, as these fuels run out, they'll keep getting more and more expensive. At an exponential rate. As they are riding that curve towards pricelessness at their very end. Thanks to Putin's war, we've seen how economically devastating that could be. There's a "cost of living crisis" and natural gas prices have shot through the roof - and thanks to slightly stupid marginal supply rules, electricity prices have massively shot up, because we all get charged by the most expensive source, which is gas right now. Economically, it's this bad. And it's only the cutting back of one supplier - not even the full loss, because even the EU is still forced to buy some Russian oil and gas. So imagine how economically apocalyptic it'd be to permanently lose not just one supplier but, one by one, every single supplier of fossil fuels. So when we say that oil or gas or coal has so many decades left, that's until the fuel's extinction. Your ability to afford it - for anyone to afford it - will die far more quickly. And, again, as gas and oil prices double, then triple, and keep rising, it becomes inevitable that you will have to step off the merry-go-round. You just won't be able to economically afford anything else. And, truth is, you should be stepping off that merry-go-round now, because it can only get more painful from here on in. While, on the other hand, renewables are already the cheapest form of energy. They'll get cheaper, as economies of scale kick in and technologies matures. And - in the current climate, this might be most significant - they're economically stable. They only depend on the Sun continuing to rise and set (or, for tidal / wave, that the Moon continues to exist), which are amongst the safest bets you could ever make (plus, if either of those things ceased to be true, then we're screwed and worrying about how to power your shower and toaster will be the least of your concerns). Therefore, as I say, the inevitability of 100% renewables is guaranteed. It's only a temporary "illusion of choice". Soon enough, that choice will be taken from you by the depletion of fossil fuels - there won't be any left for you to choose - and, well before that "final day" of oil and gas and coal, their prices are going to go exponential. Putin has unintentionally given us a "sneak peek" - a preview - of how economically destructive that's going to be. Because the West giving up just one supplier - in Russia - and not even doing a terribly good job of it, as even the EU is still buying some Russian oil and gas, despite not wanting to, for a lack of having the capacity to just completely drop Russian supply altogether overnight. Putin "playing with the gas taps" can do this to the world economy. So imagine what, say, Venezuela reporting "sorry, no more oil left" - the permanent loss of suppliers - would do. And then, say, Iran reports "sorry, no more left" shortly after them. And the dominoes all fall one by one. Imagine how economically catastrophic each permanent loss of supply would be individually, and then realise that they'd come at us, one after the other. Until, eventually, all suppliers report "no more oil left". And please note that, in this argument, I've only utilised nothing more than basic arithmetic. And, economically, it's no more than "supply vs. demand" - the supply is going down and the demand is going up, so the price can only increase, at an increasingly exponential rate (this won't just get worse, it'll start getting worse, faster and faster). I've not mentioned - because I really don't have to - anything to do with climate change here. But, for the record, that is a thing and it has its own set of catastrophic problems to pile on top of the basic arithmetic I've covered (not "instead of", but "in addition to"). Finite things run out, and the cost of finite things, as they run out, gets exponentially more expensive. These two "basic arithmetic" facts are all you need to know to realise that 100% renewables are inevitable - and the only way to avoid a world full of economic pain like humanity's never seen before. Indeed - apologies to Greta Thunberg and David Attenborough, as I do like and agree with those guys - but the emphasis on climate change has sometimes been unhelpful. It's a nebulous abstract concept, seemingly in the future, that a lot of human beings just can't mentally get a grip on to feel the urgency. It's too intellectual a concept to trigger the average person's emotional alarm bells. You can intellectually think "yes, I see how that could be a problem", but it doesn't naturally trigger people's "oh shit" panic instincts. Their emotional response. Which is what you need to actually panic people enough to get off their arses and do something about it. Whereas, we all pay bills. We're all, right now, feeling very much poorer - doubly so in Europe, but the whole world economy is feeling it, to some degree - and we're having to act immediately, by turning down the heating (or not turning it on at all) and using as little as we can, because there's nothing "abstract" or "remote" about the electricity and gas bills landing on your door mat. If we'd had someone like Greta, but who'd been making the ECONOMIC case for the past few decades, then we'd be in much better shape right now. No offence, Greta. Love you. But even you must concede the point. Hit people in the wallet, and you get an instant reaction out of them. If there's any upsides to Putin's pointless war, then it's that he's given us this "sneak preview" of the economic damage that will be wrought, if we cling onto fossil fuels, as the suppliers die off one by one. If the (slightly half-arsed) voluntary loss of one supplier - and only to the West, as China and India keep buying Russian oil and gas, no problem - can cause this much economic destruction, then imagine the wave after wave of apocalyptic disaster that would come from riding this roller-coaster to its inevitable conclusion, where suppliers, one by one, start reporting PERMANENT LOSS. That they're gone and are never coming back. It will wipe out whole economies. I don't just mean the usual depression or recession there, but actually causing total economic collapse. Whole currencies ceasing to exist. We cannot ride this roller-coaster to the end, as the tracks are leading to a very big solid brick wall and we're going to slam into that at 1000mph. Step off the ride now. You have been forewarned.
