Freikugel : And Trump thinks coal will see a revival. Ridiculous.

Larry Pinhead : guess it's a wind wind situation

AIIUserNamesInvalid : energy without destroying the planet, i love it. we're going forward.

Quarz_dk : So it looks to me like the future is coming, whether the oil industry wants it or not. Good news for everyone!

potato psoas : everyone loves Elon Musk

Arman : The stone age didn't end for a lack of stone...now that is a profound statement, especially coming from a Saudi oil minister ))

fungussa : The GOP and Drumph are probably whining and crying that renewable energy companies won't support the Republican party, and there's pathetic Drumph trying to prop up coal.

Hardik Nagar : Amazing lecture!

HAT HAT : Great lecture... however, solar energy uses light lux and not sun heat (C or F)... 20 C is the ideal temperature for a solar cell to produce electricity... that is why solar will work better in Germany than more "hotter" places...

Wikus Van De Merwe : I'd love to see and electron and synthetic hydrocarbon economy. Excess power, especially when it's under 1c/kWh, could be used to generate liquid fuels. Methanol for example, could be used in fuel cells to generate power and heat, shifting summer excess energy to winter need.

Mo A : Try telling that to Donald Trump and his audacious old world thinking of the Koch Brothers branding Clean Coal, and the low middle class tier who have only one skill is to work in the coal mines.

Mario I/O : ENEL is an Italian company, not Spanish.

HVAC Mike : where do i buy your 30 cents a watt panels 80 cents to $1 are real numbers for a private individual.

sanjuansteve : I do my calcs on the cost per kWh of solar power amortized over 35 years (including solar degradation), a common industry product life number which brings the cost down under $0.04/kWh (under $0.03 with incentives in most places) for residential scale, installed solar.

mads max : The singularityU doesnt take into account that sustainability and efficiency are a direct threat to the market system. That is why we have planned obsolescence and waste in all design. Wake up to this common knowledge and factor it into your discussion.

Alex Cannara : Very smooth salesman for wind/solar, is Mr. Naam! But, as for most salesmen, it's what he leaves out, or craftily slips quickly by, that exposes his misdirection & lack of energy knowledge. For instance, his slide on "Wind Power Cost" is impressive, but hides the flat portion at the end and fails to note that nuclear power has long been cheaper, remains so, and has far higher reliability and far lower environmental impacts. A 'good' salesman never mentions better competition. ;] Naam displays his lack of engineering/science knowledge as well in his wind slide claiming "The technology Keeps Getting Better". If he were giving accurate evaluation of wind, he'd know about things like the "Betz Limit" and the massive resource consumption & pollution from wind-power deployments. And, he'd not hide the fact that the most common wind outputs (darker blue) are getting very little better, simply because of fundamental scientific facts, like wind being subject to climate and climate change as well as low conversion efficiency, as expressed partly by the Betz Limit for prop-generators. For comparison, nuclear power operates fully about 90% of every year, even through hurricanes, polar vortices, ettc. Wind is barely delivering 20% of the power its machinery is built for, thus wasting about 80% of its materials and production, as Germany has already demonstrated and this simple simulation shows: https://www.youtube.com/watch?v=zc7rRPrA7rg In other words, the slides Naan moves quickest through are the most damaging to his sales effort. His solar slides similarly misrepresent science & engineering facts -- the most humorous is the attempt to display how much solar energy is available in Calif. -- a bit more than 1/2 each day, apparently regardless of season. and his attempt to mislead by suggesting wind in Calif. compensates for darkness, etc. -- all simply displaying ignorance of how Calif. 'renewables' actually work, and forgetting their dependence on fracking, leaking & burning gas for backing them up most of the time every day. If anyone wants to see the graphic & data facts for Calif. 'renewables' that can't be included here, examine section 2.2 of sworn testimony from real scientists/engineers here: http://www.cgnp.org/CGNP_Direct_Testimony_01-27-17.pdf But, apart from Naam's willing misdirections, why is Singularity U. so easy to fool? The planet does not benefit from selling. It benefits from thinking. If we don't attend to facts our descendants will have every right to spit on our graves, if those can be found. -- Dr. A. Cannara 650 400 3071

Drino Man : we need to get rid of oil tankers or 17 shipping ships that are equivalent to 500M cars. All the cars in the world. #noMoreShippingShips

SNAKY : 8:25 thanks camera guy

Pasandeeros : Hey dude, just so that you know... Sun is barely over the horizon for some 4-5 hours per day in the winter. Except in the north of the country, where it is below the horizon for about two months straight. Of course, it is exactly the opposite in the summer, but we'd like the energy most when it is dark.. and cold!

Santosh D : Thanks for such an insightful presentation.

FeelingShred : Cities Skylines getting in real life? And what about the components required for solar panel manufacturing? Minerals still being mined by slave children in Africa and other forgotten parts of the world? Not so "clean" energy as one would expect.

toneal30 : Great speaker, horrible audience

expert image clipping : modern strength storage technology could be very costly, so electricity needs to be generated while people need it. solar is value aggressive, solar + garage is not (but), and we can't manage while the solar panels produce strength.

WarBoy : dong energy ^_^

Quincy Flunt : my natural gas has always been free

Joe Black : Greatest superpower of solar + batteries is that it allows countries to lower their generating capacity, because of the way energy is used over a typical day. A lot during the day. A little bit during the night. With traditional generating capacity a lot of it is just for peak use. So basically when people get home and cook food, etc. Solar + Batteries is simply perfect together. And not just can solar + battery cater for all usage scenarios with less total generating capacity, but solar and battery can be used AT HOME. Freeing national grids of even more peak demand.

earthlingmajor : is this the channel where the original videos are posted?

Muhammad Safeer Rizvi : Fantastic lecture! Thank you for sharing.

John Hogan : Thanks putting up this presentation. Razem delivers a good talk on the matter with polish and ease. On reflection I wish he'd spoken about the various means of storing energy aside from chemical batteries. I think I caught a glimpse of air pressure on a graph but nothing like it was discussed. My understanding is that compressed air is potentially cheaper and pumped hydro dams are already much cheaper. Anyway, I thought this was well thought out and well delivered.

Espen Sales : Now thankfully we won't need to rely on dirty politicians to go over to renewable resources!

Schlomo Weissbergman-Goldsteinwitz, Ph.D. : The goyim will actually believe this. Enjoy your soaring prices. p.s. Those jobs are never coming back.

Sunny Mon : Planetary health vs money... Yeah, I think Solar has always been cheaper - it just costs money.

2Awesome : Going overbudget = money going into people's pockets...

Joe Black : Well fossil fuels have historically benefited relatively few people in many places around the world. Oil and natural gas may yet remain important chemical feed stocks. So I would push back the date at which it becomes economically nonviable just due to that. I do not think countries which currently rely on fossil fuels should oppose clean energy. I think they should retool towards knowledge and information economies.

Unknown SECT : Canada seems pretty dark, Eh...?

Allen Mathew : We must thank Elon Musk big time...

Shan Rafnezden : This talk should have gotten a standing ovation....

L. Johan Nissen : Ramez is an excellent speaker.

Ticket Attorney : Is he taking into account the countless government subsidies in (failed) companies like Solindra?

LE0NSKA : this gives me hope...

Jake Roosenbloom : This video has been on the front page 2 times but still has 100k views. Super weird

Insanely Raw : Fascinating topic, great speaker. Thanks

Steven Marsh : In regards to peak demand for petroleum, I think that 2030 is overly optimistic because it will take decades to build out the electric vehicle fleet, but these futurist types get a pass. Electric vehicles aren’t free right now either, and that is part of my rationale as well. The other reason to be skeptical is because of the risk that climate change poses to this plan, if the predictions are correct the virtuous cycles of the energy disruption could be disrupted by the climate scramble that humans may find themselves in.

VIPKID Vault : Just about every time he said "exponential," there was a graph behind him showing a straight line.

L Petillo : Thats actually NUTS

Paul : At around 18 minutes did he just recommend a nuclear reactor in Japan? You mean where the earthquake and tsunami absolutely screwed their nuclear reactor?

Lord RW : its not the cheapest, its simply wrong. The cheapest source of power is water power, from dams and such the price difference is so big there really is no comparison between the two. not only is water power cheaper its also lets you produce power at night AND if you have excess power coming inn you can use the water reserves as power banks and pump water in to the reserves.

QuickMix : The problem in Africa isn't energy, it's water. You can't really pull water out of thin air with electricity...

NexusARC : Am I the only one who is disgusted whenever someone you needs to do this while in charge of a company that if we did it would make them rich? I am not saying I think clean free-ish energy is bad, I think the world needs it, but when some asshole on stage is telling groups of people I feel dissociated like watching any corporate presentation it is all about money, it's not about morality, it's not about common niceness and making the world a better place. Never look at it if it is best for everyone but look at it as who stands to gain the most out of this. Also is it even good for the planet to connect the whole world with light? We used to be able to see the cosmos before light pollution. Sorry but I can't stand when I feel like someone is trying to scam me and this motherfucker gives off that vibe. Before anyone assumes my political alignment I have given up on politics and deciding how to rule over people, I hate Bernie, I hate Trump, and I hate the rest of them.

softminimal1 : What I want to know is do they factor into the price of coal fired power plant the damage to air quality, the cost of digging the coal out of the ground, the price of getting the coal to the power plant, the price of exploration to find the coal, the cost on the health system to look after people with respiratory problems caused by coal dust? With solar you float the panels above the ground so there is very little damage to the land used. The panels sit there quietly making electricity for decades with only small amounts of maintenance required. This is a no brainer, the only problem holding this tech back are the fossil fuel industry and the governments they bribe.
