I think govts all over the world need a guy like Michael advising them - laser focus on the big picture and what's most likely to give best bang-for-buck the quickest. I'm generally not a fan of venture capitalist types, but perhaps that mindset (used for good, instead of evil! heh) is what we really need to move forward in the most efficient way. It's also heartening to hear someone echo my exact political sentiments at the end, there. I've been saying for decades that democracy can't even work until we cap or remove campaign donations, as it's an obvious conflict of interest. Add to that the revolving door between cushy fossil fuel multinat consulting positions and politics (put long embargoes between when a pollie can retire and when they can then go work for them, or vice versa).
I knew this guy was clever but he deserves way more attention. Not a nuclear addict but I agree about Germany's climate crime switching off their plants way too early for politic reasons.
Considering I'm about to replace an old solar thermal system here with solar PV, I'd agree completely with Michael. There have been a number of drivers for my decision, but one of them was last summer when I noticed the water tank was up to temperature before 11am in the summer, so all the rest of the solar power landing on the panel was effectively wasted because there was nowhere for it to go.
I like your comment but would like to raise some questions. As you said it was in summer, what about during sunny winter days? Wasn't your old system sized to fit a year globally. As far as I know, but I do not have figures, it is much more efficient to heat water with thermal than solar PV and resistive heater. So you're gonna have electricity for other applications but also consumme more to get hot water. Lastly, note that PV efficiency lowers when panels get hot.
Fantastic session very interesting but a great summary of available energy sources. Michael is very knowledgeable and I think even handed in his assessments albeit passionate ( great).
We in Perth have 6.5 kW of solar and a Tesla powerwall 2. We now have $3000 credit with the electricity supplier. There is also huge potential for pumped hydro here and all around the world as well. There are several big green hydrogen projects in WA. Even old mine shafts can be used!
Thanks Rosie, a great conversation. I was especially interested in your gas 'asset stranding' comments. A good topic for the next video would be the FUD being disseminated by the gas industry in Victoria in response to the State Government's recent decision to ban gas connections for new homes. Not one mention about the economics of gas versus renewable electricity and the potential transfer of asset stranding risk back to taxpayers when owners of existing home start capping their existing gas connections. I for one built a new home 10 years ago with no solar and mains gas for both hot water and hydronic heating. I have since bought an EV. Oh how I wish I had installed solar panels and heat pumps!
Here in Ireland, the regulatory capture and bullying rather buying of politicians is being done by the dairy industry, not the fossil-fuel companies. The effect is the same, the hamstringing of our efforts. (and like the fossil-fuel companies, they live off the subsidies WE give them.)
The problem is not that engineers have not been working on energy transition mechanisms. The problem is the scale of global emissions, which have not gone down, and appear to continue to go up. Energy transition has to be done, but it is unlikely to be sufficient to stop damaging climate change.
Around-ish 30.00. The guest, doesn't ever seem to get the real thread of her comments. (If I have) Rosie is saying, "We use so much energy as heat, industrial, heating our homes etc., why insist in delivering that energy as electricity, just to turn in back into heat...not as an inefficiency, but as it's sole purpose, when it is soo expensive to store that electricity for months and soo cheap to store it as a big hot pile of clay." Maybe he has never imagined district heating schemes.
I got Rosie's thread *precisely*. She was asking about seasonal heat storage, and I said it was expensive, but I was all for it as long as it was not over-engineered. The system I visited in Alberta was at Okotoks: lovely engineering but it cost £100,000 per home - vastly more than a simple ground source heat pump would have been, in a region where natgas heating cost a few hundred dollars per year. I also pointed out that just because you are storing heat, that does not automatically mean you should generate it thermally: you can generate power via PV, and then use that to drive a heat pump - which almost certainly generates more heat per m2 and perhaps per dollar, as well as giving you the option of using power too.
greetings from south germany we live about 20km away from Geretsried and the geothermal wonder power 😂😂😂😂😂 unfortunately wie did not receive an invitation for the bloomberg event a few weeks ago...
Great episode, loved it. Could however have grilled Michael on geothermal and ocean/wave/tide. In one instance he is talking about liking things that scale and in another he discusses the much higher value of work compared to heat. Based on the research I have read, global potential of renewable energy flows are the following: -Solar ~4 orders of magnitude more than current fossil consumption -Wind ~1 order of magnitude more than current fossil consumption -Geothermal work several orders of magnitude less than current fossil consumption -Ocean+wave+tide several orders of magnitude less than current fossil consumption
I think you'll find all your orders of magnitude are way out. As for geothermal, look at ground and water source heat pumps, as well as closed loop geothermal, not first generation or fracked ESG. Closed loop power generation could be done in about 80% of power network areas globally. Not to mention using it in district heating systems currently stuck using waste heat from gas or coal plants.
I am off-grid with solar and home batteries here in Thailand, but I still installed solar thermal hot water, because when I need hot water it is not sunny. Solar thermal seems a more efficient system for heating water that electrical resistive heating. I can make more hot water on a cloudy day than that I can make the electricity to power a 5kW water heater. Solar Thermal is also a thermal battery that uses an insulated tank to store hot water over several days.
I bet if you installed PV plus a heat pump you would get much more hot water than you do from solar thermal. And you could use the excess power to watch UA-cam videos.
@@MLiebreichThe solar thermal system cost just over $1,000 and I was able to install it myself. Houses in Thailand don’t have heating and use spit aircon units for cooling. Water heating is via instant electric water heaters.
Plus the driver for PVT at utility scale in the context of networked ground source heat pumps (the cheapest route to electrification of domestic heat at scale in cities) is massive. Not least because it can reduce the stagnation temperature of PV by 30 degrees C or more (from around 50C to 15C). With temperature coefficients of half a degree, the increase in electrical output alone is a good enough reason to do this, let alone the increase in SCOP of the heat pump. Rosie clearly gets it. I think Michael needs to do some more homework.
I don't upload these as podcasts (perhaps I should?). Michael Liebreich has a podcast "Cleaning Up" that he puts on YT plus podcast stores. Coincidentally, I was the guest on his latest episode ua-cam.com/video/iitDrQNDo3U/v-deo.htmlsi=Uk1R9Owv8ujfCQOc
Eva may be able to thermosiphon, but there's no such thing as a free lunch. Thermodynamically, a thermosiphon is nothing more than a relatively inefficient heat engine. Therefore relying on thermosiphons to generate pumping work is equivalent to diverting a proportion of the output of your geothermal plant to drive electro-mechanical pumps. i.e. the more you rely on thermosiphonic heat delivery, the lower the output of your plant will be. Its only because the example cited by Michael involves venting heat that there's enough thermodynamic potential for a thermosiphon to be set up.
Rosie, Greta is right. Most engineers and academics have wasted time while the planet burns. She’s more right than wrong. If you’ve spent your life designing and installing renewable energy systems as fast as you could, then don’t feel bad about what Greta says. Greta has accomplished more in her teenage years for humanity than most engineers accomplish their whole life. She’s got a pretty strong point.
Start making homes independent…then neighborhoods…then towns….then city’s…then counties….then states….then counties….then continents. Take care of the the small stuff and the grid will take care of itself.
Nice thought. You use vastly more energy than your home can produce, and I'll bet there are periods of weeks when your home would produce far less than you even use at home. There are no easy ways to do this stuff.
". . . For some reason [Australia] decided not to invest in good internet." Oh Rosie; you sweet, naiive Summer-child. . . We have crap internet because of certain politics and the impact of certain lobbyists
nuclear is to expensive and to dangerous and it is not renewable and its emissions are totally unclear i know numbers between 5gr/co2e/kwh - 289 gr/co2e/kwh
Here's a link to the video. If we need a "bridge" technology to carry us from dirty fossil fuels to clean energy, we may need to embrace nuclear as that bridge ua-cam.com/video/L31px6rQ-vQ/v-deo.htmlsi=KFAMGNJ8mZTpF8wo

My speakers died, and while I am waiting for replacement I am using my laptop's built in speaker to hear things. This was one of the easiest to hear. Good volume, and very crisp. There were many other videos that just simply did not have the volume. I really don't know what problem you had.
His microphone was loose or something like that. I couldn’t listen more than three minutes. Having a third party that can send instant feedback to the creator to stop and fix the problem is a good idea, but probably a luxury many channels can’t afford.
In Principle, the arguments for Energy efficiency are restricted to fighting the counter position of a defence already overwhelmed and struggling to survive by desperate means, the "We had to destroy the Village in order to save it" position of a soldier who has lost all human feelings of civilised standards. The Principle of Singularity-point Lensing of relative-timing that "with our thoughts we make the world" actually applies, by Observation, without argument other than that which is self-defining, means the MAD Mentality, destroy the world for "compensation", profit and a Dark Money reserve of intrinsically worthless Fiat Currency, is a simple fact of deliberately ignored contrariness that you risk your own self to say out loud.
@@MLiebreichA theory of mind problem or derivivation of the definition of existence of energy? Maybe intellectual inertia, it takes 20X as much time to realign the state of learned information, in Sciencing categorization sense, as it does to directly absorb what the teacher or environment shows you. I've been pro Nuclear power for 50 years and only reluctantly admit that very inefficient alternatives have a good case to make, mostly because industrial inertia means we can't just stop dead using fossil fuels. IMHO continued political treason in the core problem, but as in either a Court of Law of science laboratory a thoroughly rational and reasonable presentation of observable facts is required to shift the whole paradigm.

@@MLiebreich I've heard a lot of overconfident nationalist bullshit living in Zimbabwe - prosperity always requires sufferning during the 5 year plan and benefit later except later it turns out that there's another 5 years to go. It's always the external enemy (foreigners, the EU, colonialists, Americans, British take your pick) who are responsible for the problems too! So far you're not convincing anyone that you chose right on Brexit and given that most of your other arguments are heavily reliant on us trusting your judgement (i.e. they're not really independently verifialble scientific facts) we cannot place a high value on them.
Wrong about Switzerland’s reservoirs’ contribution to its energy consumption…also improvements on grids will eliminate many transmission constraints…that said, reservoirs have other longer term ecological issues, as many old ones are being demolished now..
I know that you and almost everyone else agrees that Airborne wind energy systems are a non-starter. But I have two prestigious scientists who agree that my system has Merit. John bardeen is the only person who ever received two Nobel prizes. Paul Cutro was the NASA engineer responsible for judging the merits of inventions to receive Awards. When I discuss this in 1975 with John we agreed that Steel was an inadequate material for the cable. When I showed the design to Paul in 2005 he felt the design could easily be executed at the 10 megawatt scale. I hope that you can take the time to study the design
It has been suggested that populations are reducing in some countries and may crash in the next decades. If so, CO2 would decline, and climate change may be delayed by this one outcome. Population pyramids are not pyramids now. If this is so, we may be able to be more economical in our investments. Success depends on solving the right problem and taking into account the time frame constraints. This topic may deserve its own video..
Michael is so very very wrong about the future of airborne wind energy. It can be made far more robust than a turbine because you can have a quiver of kites for different wind conditions. A big one for slow winds and a small strong one for high winds, and others in between. He says we need floating wind. Well kites are by far the best way to do that. No need for the enormous floating structures they are presently building to try to resist the overturning forces. A kite system needs maybe 100 times less mass for the same energy generation ability. Controlling kites and developing automatic launch and retrieve systems is complicated and will require significant funding. It is the lack of research funding holding us back, not the potential of the technology.
So in Ontario Canada the Natural gas company is going to push Hydrogen in their pipelines. And you can heat your home with it. Austria has made green ammonia and has already swiped it to Japan. What does Japan know that you guys don’t. If you worry about the cost you don’t understand the cost of saving the planet.
Oh dear. If you think hydrogen blending is the answer to heating you obviously haven't heard of heat pumps. It wasn't Austria, it was Australia sending hydrogen to Japan - one tiny shipment of 0.2% of the energy content of an LNG tanker, 25% end-to-end efficiency, at a cost of half a billion Australian dollars, and there was a fire on board the ship. Oh, and the hydrogen was made from coal. As for costs, if you really want to save the planet, you have to direct your money at things that actually work, not waste it on the stupid stuff.
There have been trials in the UK to heat homes with H2, pushed by British Gas down our throats to keep people burning stuff. It doesn’t work, it’s costly, dangerous and people don’t want it. Induction hobs and heat pumps: that’s all people really want and need (with solar PV 😊).

It's always the external enemy (foreigners, the EU, colonialists, Americans, British take your pick) who are responsible for the problems too! So far you're not convincing anyone that you chose right on Brexit and given that most of your other arguments are heavily reliant on us trusting your judgement (i.e. they're not really independently verifialble scientific facts) we cannot place a high value on them.
Wrong about Switzerland’s reservoirs’ contribution to its energy consumption…also improvements on grids will eliminate many transmission constraints…that said, reservoirs have other longer term ecological issues, as many old ones are being demolished now..
I know that you and almost everyone else agrees that Airborne wind energy systems are a non-starter. But I have two prestigious scientists who agree that my system has Merit. John bardeen is the only person who ever received two Nobel prizes. Paul Cutro was the NASA engineer responsible for judging the merits of inventions to receive Awards. When I discuss this in 1975 with John we agreed that Steel was an inadequate material for the cable. When I showed the design to Paul in 2005 he felt the design could easily be executed at the 10 megawatt scale. I hope that you can take the time to study the design
It has been suggested that populations are reducing in some countries and may crash in the next decades.
If so, CO2 would decline, and climate change may be delayed by this one outcome.
Population pyramids are not pyramids now.
If this is so, we may be able to be more economical in our investments.
Success depends on solving the right problem and taking into account the time frame constraints.
This topic may deserve its own video..
Michael is so very very wrong about the future of airborne wind energy. It can be made far more robust than a turbine because you can have a quiver of kites for different wind conditions. A big one for slow winds and a small strong one for high winds, and others in between. He says we need floating wind. Well kites are by far the best way to do that. No need for the enormous floating structures they are presently building to try to resist the overturning forces. A kite system needs maybe 100 times less mass for the same energy generation ability. Controlling kites and developing automatic launch and retrieve systems is complicated and will require significant funding. It is the lack of research funding holding us back, not the potential of the technology.
So in Ontario Canada the Natural gas company is going to push Hydrogen in their pipelines. And you can heat your home with it. Austria has made green ammonia and has already swiped it to Japan. What does Japan know that you guys don’t. If you worry about the cost you don’t understand the cost of saving the planet.
Oh dear. If you think hydrogen blending is the answer to heating you obviously haven't heard of heat pumps. It wasn't Austria, it was Australia sending hydrogen to Japan - one tiny shipment of 0.2% of the energy content of an LNG tanker, 25% end-to-end efficiency, at a cost of half a billion Australian dollars, and there was a fire on board the ship. Oh, and the hydrogen was made from coal. As for costs, if you really want to save the planet, you have to direct your money at things that actually work, not waste it on the stupid stuff.
There have been trials in the UK to heat homes with H2, pushed by British Gas down our throats to keep people burning stuff. It doesn’t work, it’s costly, dangerous and people don’t want it. Induction hobs and heat pumps: that’s all people really want and need (with solar PV 😊).
@@MLiebreichsending Hydrogen to Japan was more of a proof of concept.
@@zen1647 Give me 500 million Ozzie dollars and I bet I can prove any concept that doesn't outright break the 2nd law of thermodynamics.
