The speed of technology and the ways virtual life are reinforcing alienation is not helping. How do we counter negative identification - nationalism, racism, sexism, unchecked corporate power and the lack of any substantial ethical basis for money and international investment? I like Julio's energy and enthusiasm AND a lot of fences are going to need to come down to make what he envisioned work. Personally I don't think people will ever build a just society because there are simply too many "competing" interests among 8 billion people.

Does the 60TW future energy estimate include all the current losses we have in the grid with today's energy sources? Current IEA & USD0E surveys show 2/3 of all energy produced goes to waste mostly due to heat (burning stuff) lack of instantaneous consumption (more produced than consumed). Renewables are bringing with them massive grid storage and with that the grid energy waste will reduce between to 1/3 to 1/2. Thus, the 60TW may be a much higher estimate than we need to worried about. That is, the future energy target is likely much lower than we normally worry about.

Mr Friedmann is right when talking about the sun and the earth, but forgot to take into account the total investments needed. We calculated the investments to replace 95% of all fossil fuels. Even with the optimistic scenario of the NREL, the CAPEX is astronomic. He also forgot to mention the limits of the available metals (the IEA published several warnings about copper, lithium, cobalt, etc). Neither do we have enough solvents to produce huge quantities of highly pure metals. He is right that a lot of investments are needed, but even if we multiply by 3 all investments into the energy sector, we only will be able to replace a third of the fossil energies in 30 years. And many of these investments will have to be renewed after 30 years!

You are the generator, the load is the weight and the rope is the means by which you transfer the energy. (electrical wire). The rope and the wire transfer the energy. The electricity is like the rope, it transfers the energy. Solar panels converts the sunlight into electricity and without a load it just sights there like the rope, doing nothing until it needs to be doing something, like a heater or a motor. There is electricity in your socket outlet, but not energy, until you connect a load. That is fundamentals.

Another method to plausibly transform ambient heat into electricity with equivalent cooling essentally consists of two electrodes closely face to face (~1 micrometer) in a vacuum wired to an external electrical load. The face of the [Emitter] electrode is covered with a uniform array of LaB6 tipped small diameter carbon nanotubes grown straight out. The face of the [Absorber] electrode is covered with small scale graphine flake char. [Rice U 2014] Thermal energy mobilized unattached electrons will tend to free themselves outward from the emitter tips and drift at ~1 million meters / second @ 25 millivolts (thermal electron energy @ 20 C) to the absorber which tends to collect them. A negative charge accumulates on the absorber. This repels oncoming electrons slowing their forward drift, cooling them. The absorber electrode charge is simultaneously the repelling cooling and the external electrical load voltage. The drift current and external wire route current are the same. The DC electrical power consumed by the electrical load depends on the load resistance. Thermal energy absorption always equals the electrical yield. Wire resistance is a practical loss not a true loss so lt is overcome by added device output. Extra cooling then balances the heat given off by the wire loss. The performance of the device is expected to be modest in the beginning but improve rapidly. Even early devices are expected to last a long time. There is little place for obsolence if the first installed device works adequately. They will withstand being short circuited indefinately up to an electromigration limit.

Carbon taxes are an interesting idea, but the problem is that they need to apply EVERYWHERE. Keep in mind that the same amount of Coal-fired power generation as used by the USA is being added to the grid every year - and it's nearly all in China, India, and Indonesia. Oddly enough, those same countries did not sign the COP28 agreement - go figure. Coal is reliable and cheap to build, and you don't have to worry about being outbid by a richer nation if you have local deposits, so it is a power source of choice in poorer countries. CO2 emissions have been declining in the USA and EU for a couple of decades already (mostly because of switching from coal to methane power), but China's emissions now dwarf that of the rest of the world combined, and also the entire historical emissions of European countries. So, you can be as virtuous as you like in the UK or USA etc, and local carbon taxes will likely reduce emissions there by another 20% or so (wild guess) - and it won't make any real difference in total global emissions of CO2. CO2 emissions may even increase overall.

Remove the information I can find global primary energy consumption in 2023 was 620 exa Joules, or 19.7TW average power not 26TW, so the amount we use is somewhat lower than Julio Freidmann says. 93.59 There's more good news too. The number Julio quotes is primary energy demand, a lot of which is currently wasted because burning fossil fuels is an inefficient way to use that energy. By electrifying a lot of our heat and transport we will can reduce the amount of primary energy we will need, probably by at least a third. On this basis, demand in 2015 is probably more likely to be around 40 TW rather than 60 TW. The significance of this isn't so much the amount of energy reduction but the fact that requiring 2/3 of the energy means we should be able to build it build it in about 2/3 of the time which means we can tackle climate change faster because we are using energy more efficiently.

It’s one thing to be optimistic, it’s another thing to be delusional. Here in the U.S. we are $33 trillion in debt and digging ourselves into deeper hole every year. Decarbonization may be one of our least important priorities in the coming years.

Having the target of cheap and abundant energy is the biggest flaw. Scarce and valuable resources are what move the world and bring profits, so of course none of the rich and powerful really want this.

None of them are powerful enough to stop it. The fossil fuel industry is trying its best to slow it down but technology and abundance will win out.

The world needs 8-10 billion solar panels but the problem is solar panels cause global warming. Sunshine on the planet produces about 1000 watts/m2. A 350 watt solar panel is 2 m2, so a panel produces 175 W/m2 of electricity. So what happens to the excess solar energy 1000-175 = 825 watts that hits the panel? Energy is not created or destroyed only changed from one form to another. Black bodies such as solar panels do not reflect light/energy like primary colors or white do. Solar Panels absorb the solar energy and reflect most of that energy back out as heat. This is the same as a heat island effect caused by a city. Billions of black solar panels will create massive heat islands and warm the planet.

First of all, I have a problem with 10 billion people. We’re constantly euthanizing Dogs and cats say for example because apparently there’s too many of them but at 10 billion people on earth. Well that’s certainly not a problem. And then you wonder why you have Geo political issues which lead to another big problem with energy. So yeah lotta hot air everywhere.

This is my least favorite TED talk. The philosophy of "we need more" attunes to current economic life principles and completely ignores the principles of the planet. I personally believe we should be asking "how can we do with less", and "how can we develop our systems to attune to the planet". This man is obviously very excited about numbers on paper, but shares a vision of the future that makes my heart ache. I think we could do much better, but that would require an impossible shift.

If Megan Markle or Kamala Harris did a speech on renewable energy, this is what it would be. How can someone who describes himself as a chief scientist be so naive? First, a real scientist does not describe the colourless, odeourless life-essential gas, carbon dioxide as 'carbon' (dirty black dusty solid). And he wants poor African nations, where average daily income is $2/day to export their energy to Europe!? Kenya is advanced on renewab les, but still most of its population remain as subsistence farmers without the electricty or other energies for tractors, farming machinery, refridgerators, abundant fertilisers, and getting 80% of their energy needs from wood. Ahh, regardless of what he says, he is not doubt on a good $100k+ salary paid for by the massive government subsidies for renewable energy projects that can never pay their own way. We already have massive infrastructure, innovation, technology, cooperation, etc. That's the industry that provides us with 80% of our energy needs, and is growing - in parallel with renewables, not being replaced by them.

How is it that a simplest matematical formula is so difficult for us human to solve ?? More population, needs more resorces and more of everything , what about if tge population number STOP GROWING , Not to kill those exist , but NOT to bring more kids into world, by only 10 years( i said this 35 years ago , again 23 years ago, 13 years ago and all the time since ) yes, by only 10 years stoping the growth in population, those who dies is a reduction and all together population drops at least 2 billion , could be more. I sterilised myself after first kid , 31 year ago, with the same thought. I have 1 wonderfull son , my friends who laugh at me on my theory, they have, 3 , 4 , 5 , 2 , kids each one . By just looking at this : my son do not want car, not driving. Lives simple. Not a kilo meat or fish or chicken in freezer , no caviar , fish egg in tubes .Those kids of my friends, they all have at least 1 car each, and their freezer full of meat, fish, chicken , tubes of caviar with 100000 fish egg in . And high consumption in all. So simple matematic . Education, i learnt this at age of 12 and from that time untill now, those who like me got the point ( i know many , relatives n friends ) they also have 1 , non, or 2 kids .

This fellow is thinking about it all wrong because he doesn't understand our current situation. Abundant, cheap energy is exactly the wrong thing to give our species. The world economy is already in overshoot, which means it's using more renewable resources every year than the Earth generates each year. For instance, we are fishing more fish than are growing every year, thus depleting fisheries. (This is why the species of fish in the grocery store keep changing.) Same thing with top soil. We are eating into our capital instead of living off the interest. How much more of the remaining wildlands of the planet should we cut down for these extra 2 billion people, thus crowding out all the other species? Simultaneously, we are mining the top 50 minerals needed to run an advanced economy at an alarming rate. Ore concentrations for these minerals are shrinking and will soon become miniscule. Long gone are the days when copper nuggets were found in river beds. Average copper ore concentration in new mines is just 0.6%. Even if we got to 10 billion people, we could never keep the population that high for more than a few years as we use the "abundant, cheap energy" to continue to rape and pillage the planet, thus destroying ecosystem services. As the non-renewable resources dwindle, the economy contracts and you've suddenly got billions of unemployed people scrambling for the dregs and going to war over them. The speaker fundamentally misunderstands our predicament. Abundant, cheap energy is exactly the wrong thing to give our *rapacious* species.

I don’t believe you’re thinking in a big enough scope. Food and energy aren’t the only limiting factors of population size. The world’s highest pop growth rates were seen in the mid-20th century, peaking in the 1960s at about 2% per year. This period was marked by further medical advancements and the Green Revolution in agriculture. The global population surpassed 7 billion in the early 21st century. Currently, growth rates are declining globally, with projections suggesting a stabilization or even a decline in the world population by the end of the 21st century. This is due to factors like decreased birth rates in many countries, increased urbanization, and greater access to education and family planning resources. How it was does not have to be how it will be. People are learning, information is spreading, course corrections are already being made. A hyper abundance of energy isn’t just about food n water, it’s also about the things we haven’t even gotten to play with yet scientifically/industrially. We haven’t even thought of experiments and processes yet that could benefit from being de-yoked from energy limitations. So even with abundant energy, population growth may not necessarily increase. Historical and current trends show that as societies become more developed and educated, birth rates tend to decline, a phenomenon known as the demographic transition. This trend is observed regardless of energy availability and is more closely tied to factors like women’s education, healthcare access, and economic development.

@@MrLargonaut none of what you wrote addresses that we are in overshoot already. We are living on borrowed time as it is. See " Overshoot," by William Catton or the work of The Footprint Network, which calculates Overshoot Day every year. That is the day when we collectively use the resources available in one year. It moves earlier every year. And it doesn't matter that population rates go down if the commitment is to have the remaining 6 billion people live at the same standard of living as the two billion most rich on the planet.

@@AndreAngelantoni The calculations on the value of asteroids we've sampled from is in the quintillions of dollars worth of value. Tens of thousands of times more than the global GDP in one rock. All investment in getting one of those rocks into earth orbit, or smacked into a safe surface on the moon to be mined, is worth it, and as your resource concerns point out, will eventually be inevitable. As for the renewables, the purpose of my statements, of this video, is to be bullish on making corrections with renewable resources as well. If you don't think we can do it, that's on you, but there's plenty of us that think we can, and we'll be the ones to do it while you watch.

Problem is money poured into projects is always wasted. If the planet wants to correct its path, every compensation given for work done to build the projects needed should be food, security, housing, trade, not money. Country A builds infrastructure in country B, country B feeds and houses people in country A. Bring back barter and trade
