When it comes to cost, clean energy is bound to beat out fossil fuels, says technologist Ramez Naam. But the hesitancy to build amid the prevalence of "not in my backyard" campaigns is preventing the creation of our sustainable future. Naam outlines the changes we need to make to get out of our own way and create a stronger, more reliable renewable energy grid. "It is time for us to build," he says.

One problem though. Copper mines used to have a 20% yield. Now they have a 0.8% yield. We are running out of minerals to transport this electricity, I am not convinced by this simplistic solution (i.e. build thousands of km of transmission lines to bring the power where it's needed).
@globalvillage423
@globalvillage423 Год назад
@@antoine_marchal Copper has been in use at least 10,000 years, but more than 95% of all copper ever mined and smelted has been extracted since 1900. As with many natural resources, the total amount of copper on Earth is vast, with around 1014 tons in the top kilometer of Earth's crust, which is about 5 million years' worth at the current rate of extraction. However, only a tiny fraction of these reserves is economically viable with present-day prices and technologies. Estimates of copper reserves available for mining vary from 25 to 60 years, depending on core assumptions such as the growth rate. Recycling is a major source of copper in the modern world. Because of these and other factors, the future of copper production and supply is the subject of much debate, including the concept of peak copper, analogous to peak oil. The price of copper has historically been unstable, and its price increased from the 60-year low of US$0.60/lb (US$1.32/kg) in June 1999 to $3.75 per pound ($8.27/kg) in May 2006. It dropped to $2.40/lb ($5.29/kg) in February 2007, then rebounded to $3.50/lb ($7.71/kg) in April 2007. In February 2009, weakening global demand and a steep fall in commodity prices since the previous year's highs left copper prices at $1.51/lb ($3.32/kg). Between September 2010 and February 2011, the price of copper rose from £5,000 a metric ton to £6,250 a metric ton.

Agrovoltaics are one of the answers to land availability. Many of the vegetables that we eat would have been understory plants in nature.

In 2002 I went into nuclear engineering for a college major. It might sound ridiculous, but climate change really was a motivating factor in that decision... also some concerns about peak oil, which didn't age well. I perceived that renewables were not sufficient for the problem. When the evidence changed, I changed my position. I am very sad that new nuclear builds have not panned out economically, but I can't deny it. Solar is the only type of energy that gets built on budget because the panels are all identical, you'd have to be a major idiot to project that wrong. Yeah, managing solar availability is hard, but the costs are too cheap to avoid, and the problem is solvable. Organizations that refuse to entertain this will go the way of the dodo.

A peer-reviewed study in 2017, undertaken by the Energy Innovation Reform Project (EIRP), with data collection and analysis conducted by the Energy Options Network on its behalf, compiled extensive data from eight advanced nuclear companies that are actively pursuing commercialization of plants of at least 250 MWe in size. Individual reactor units ranged from 48 MWe to 1650 MWe. At the lower end of the potential cost range, these plants could present the lowest cost generation options available, making nuclear power “effectively competitive with any other option for power generation. At the same time, this could enable a significant expansion of the nuclear footprint to the parts of the world that need clean energy the most - and can least afford to pay high price premiums for it.” The companies included in the study were Elysium Industries, GE Hitachi (using only publicly available information), Moltex Energy, NuScale Power, Terrestrial Energy, ThorCon Power, Transatomic Power, and X‐energy. LCOE ranged from $36/MWh to $90/MWh, with an average of $60/MWh.

@@beautifulgirl219 The sad truth is that the NRC artificially makes the costs of nuclear sky high. The fact that NRC doesn't consider anything but safety in its review pushes the costs to get new designs (ie. - all of the companies you mentioned) into the billions. You can always be "safer". In the face of the NRC - how can we ever make progress on climate change using nuclear? Fun fact - how many new designs has the NRC approved since its creation? Answer - 0.

The deals, which represent a combined $18.9 billion in power sales, mark “the largest pipeline of new nuclear power plants under development in the world,” Last Energy said. The Washington D.C.-based company on March 22 said it signed PPAs for 10 20-MWe plants with Katowice Special Economic Zone (KSSE), a 1997-established special economic zone in southwestern Poland that hosts 540 companies. “The agreement represents over USD $4.3 billion in electricity sales over the lifetime of the contract and USD $1 billion in inward energy and infrastructure investment in the zone,” the company noted. The first of the 10 plants supplying power to KSSE could be commissioned in 2026, it said.

There is one (but not just only one) key advantage though. One single nuclear reactor with a 1.6GW nameplate capacity will produce 12000 to 13000 GWh of electricity per year... as much as several thousand wind turbines scattered across the land. Moreover, that electricity is at a predictable & controllable production rate, with little need for battery storage & intercontinental transmission lines. If you look at the time it takes to build a reactor (7 years to 15 years), that is just about the same time taken to build several thousand wind turbines, if not less. And we don't even need to have a 100% nuclear supplied grid. An amount that can meet nearly all or all of the minimum demand of the grid would meet the first stages of the goal. Even better if one has hydropower resources, which can be combined together (examples include Sweden, Canada, Finland, and Switzerland).

You came from capitalism. That is why they are all wrong and you were wrong. You want money no matter what happens to the world or your own life. But the fact is that you think it is ok to go into debt in order to afford to have them installed. You can't even imagine the need to install them for free on every home with battery storage. There are several reason you are wrong on so many things such as any fuels that burn are not clean. Hydrogen requires huge amounts of energy to make and the coal and gas corporations are paying off as many people of power as they can to keep themselves in power. No pun required. It is cheaper to build solar and batteries than to even start up a coal fired power plant. And then there are plastics that need to be replaced with non fossil fuels based plastics. We don't have the choice anymore of "not in my back yard" That is childish banter from cul-de-sac kids. The real problem here is the people with money must pay up after decades of cheating and stealing from everyone and exploiting everyone. They will never do it. Also Governments are sovereign so they are the only ones that can move decimal points and make new funds available yet they refuse to do it for anyone but big oil, pharma and the international arms machine. We must take away their power to say no and yet everyone is so tired and working all the time and on the edge of failing, that they simply do not have the bandwidth to stand up en-mass and force the powers that be to behave and do what is needed.

Great speech indeed, however the graph on time 0:52 may be questionable if the cost of solar will drop to 0.2 $/W. No one may drop the facts on time 1:30 where we see the solar cost 0.4 $/W, but on these world where everything goes up and up, only artificially the cost goes up only on presentations. Peoples pay more every day, this has been the past, this is the present, and these may be the future. Then today solar panels really are very good, but intermittent and then need storing and after this need distribution which are needed to provide dispatchable energy. The speaker really is right, but the real life is not what investors pay to build with low cost, the real life is what consumers pay on the bill, and so let speak for the "price", then the cost and then the profit. On addition to all the above why not speak and compare these solar energy or wind energy with secure and abundant geothermal energy, or nuclear energy and see the capital needed for kwhr and not for power, an investment which work with 93% or higher efficiency may be more attractive than an investment like solar which has efficiency lower than 15%, or wind with efficiency 25%.

Classic misdirection of using LCOE (levelize cost of Energy) to argue cost impact of green energy. This is heavily influenced by economics and politics.

Btw, solar and wind with backup have EROI’s of less than 5, and we need a minimum EROI of 10 just to maintain our current society. Otherwise we will just slide back to the standard of living and population of the Roman Empire. It has been noted by historians that one of the main reasons civilizations fail is because of decreasing EROI’s.

Great! Can we stop the insanely large subsidies and other supports for wind/solar/battery production etc? Unfortunately, it seems that even with these alleged cost declines, these technologies are still not viable. P.S. Can we fairly drop the term "clean energy" when referring to wind/solar? Can we also stop casting NIMBY in a negative light. It is good to have some controls over these things, especially on wind/solar. The more this guy goes on, the more ridiculously non-viable wind/solar really are. I bet that Oxford study is complete B.S.. Practically all of these studies promoting wind/solar don't withstand any real scrutiny. If wind/solar were so fantastically more economic, then China and India would not be building so much coal power generating ability. I would bet that this speaker is also hiding the ball on the issue of renewables in Texas. There are always incentives associated with these projects. Wind/solar remain non-viable even with the tsunami of supports from governments.

In this context, Brazil serves as an excellent illustration. With a landmass comparable to that of the United States, Brazil boasts an interconnected transmission system that enables the country to fulfill a staggering 80% of its electricity demand through renewable sources. How normally it works: the North region produces more energy than it consumes, especially during the wet season, thus most of the excess of energy is exported to the Southeast and a minor part is exported to the Northeast. In the Northeast region has a higher energy production during the dry season, which is the period with highest wind potential, thus in this period it exports the excess of energy to the Southeast-Midwest region. In its turn, the Southeast region imports energy from the North during the wet period and from the Northeast during the dry period and exports energy to the South region. Brazil's most populous region and one with the highest demand for electricity is the Southeast-Midwest at the same time is the region with highest hydropower and hydro storage installed potential. The South region's need is partially met by local resources, with the remaining portion coming from imports from the Southeast, particularly during the wet season, which coincides with the South's dry season.

Ok but here's another barrier - private sector energy generators/retailers do not want to produce enough energy, because then the price will drop. We see this in New Zealand where the gentailers like Meridian et al sit on permits to build capacity but choose not to do it, because by building more generative capacity they will oversupply the market and energy prices will drop (and actually be affordable) - so why would they do that? They prefer to maximize profit and keep energy scarce. I guess at least cheaper solar etc will make generating your own energy more affordable, for those lucky enough to have their own home and the money to buy the gear.

There seems to be a lot of rose tinted glasses being used here. Certainly , in the U.K. that cost is increaseing not decreasing. Cost apart, what is more important is value and renewables are low value with regard to grid supplied electrcity. They are second and third rate generators and are not an equivalent to conventional generators. What ever power they supply to a grid is supported by conventional for intermittency and technical reasons. We have had decades of building these devices, indeed some are already past their life span and been shut down. No stand alone grid has come near to running on them without support.

My new innovation called perpetual hydro gravity is the solution of our energy crisis. But if this innovation nobody believes me it will be buried if I have no life in this world. Hydro gravity is the answer. I know never heard of this because this kind of idea is my new design. No one's believes me. How can I introduce I have no capacity to show this that this is what we need. Hope someone give me a chance to prove that this is what we need. Again this a perpetual source of energy.

I don't get how solar or wind are cheaper; 20 years of ongoing construction projects all across the state of Victoria and they don't match anywhere near the output of the old coal power plants in rated output; The intermittent operation of a good wind turbine site produces 30% of it's rated capacity over 12 months. The wind turbines are difficult to maintain and their operational life is not very long.Before the infrastructure is completed to match the power output, the earliest wind turbines would need replacing. Maintaining and operating thousands of wind generators; 50-100 metres high, sprawled across hundreds of acres all across the country, covering thousands of acres of land compared to maintaining 2 or 3 sites with 8 powerful generators each that are all contained in a building with easy access, with tools and support onsite; This is 100 times more work. The cabling is easy to bring across the state and connect into the fixed sites, these different sized and intermittent sites are going to need wiring all over the place. Another huge construction operation and the maintenance on this new grid is going to be far more complicated. Then we add electrical storage, more costs, more complications. The construction and maintenance is going to be ongoing to keep the sites operating, replacing failed sites and servicing a far more complicated grid. It would be more work then operating machinery and putting coal on a conveyor belt. The coal is under our feet; It's ours; The only cost should be digging it out the ground. Wind and solar are good for smaller sites and for boosting the grid, they are not at all practical for large scale, high power outputs to support our nation and it's industry.

Naïve: I don't disagree that the cost of green power is falling. BUT, the modern world relies on firm power, not intermittent, so you need to add the cost of storage into the cost of green power which makes it expensive. Additionally, you are ignoring the cost of capital - the cost of fuel is discounted, whereas the high capital cost of green energy (per MW) is penalised in a higher interest rate environment. Disappointing.

If so cheap, why do the countries with the highest rate of installed capacity (Denmark & Germany) have the highest energy prices?

Easy to understand --- the hype: the projected prices per kWh by the "experts" are lifecycle cost projections, what the average cost is over the life of the project (20 - 30 years driven by country economic policies). The reality is that as solar and wind do not "pay for fuel" the great majority of their cost is in asset cost (cost of development) which is paid TODAY -- so you pay a lot NOW until the project is paid off and then the remaining years the production is really cheap as all you pay are taxes and ongoing maintenance.

Very good points! One of the common complaints about wind turbines and solar panels is: "You can't make wind turbines and solar panels using wind turbines and solar panels". This is true----but only so far. There are new CHEMICAL processes (not smelting) being developed, as we speak, for producing both steel and solar panels. And with minimal, if any, energy usage. Presumably this could be used to make the tempered glass that is required as well. It's evident that most----and probably all----problems can be worked through, given enough time, effort, and resources. The environmental movement has NEVER had to resort to its' various scare tactics to advance this technology. Their "crying 'Wolf' " tactics have always been proven false---and will be again.

@haddow777
@haddow777 Год назад
While true, it is also handicapped by the past. This is trying to use old style logic to fix the problem. We not only need to push to replace fossil fuels with green energy, but we need to escape our primitive fascination with the magic that electricity is and stop focusing all of our solutions on just generating more electricity. Green energy is just that, energy. Electricity is just one form of energy. I honestly think that a key to us moving forward is to not only clean up our electricity, but to open ourselves up to finding ways of creating our current quality of life through technologies that aren't driven by electricity. Wouldn't offsetting our electricity dependence and demand also help us reach our goals of clean electricity without having to require so many rare and harmful elements that go into solar panels and wind farms? Solar is actually terrible for generating electricity efficiency wise when compared to heat capture. Per square meter of sunlit captured, we get a lot more energy that way. So, why not use it. So much of our energy consumption comes from heat generation. In using solar to generate out heat, we could for better and more quickly displace fossil fuel consumption our of society. The map shown talks about special areas with especially high solar levels and transporting electricity over huge distances. This exposes the two strongest weaknesses of solar electrical generation. How the inefficiency of such generation makes only the sunniest area viable for generation and how transportation is so much easier and cheaper than storage. Rare and environmentally harmful, as well as extremely expensive materials are required for electrical storage. Heat storage is the opposite. Carbon in the form of graphite and sand are in abundance around the world, and they are great heat storage mediums. I'm fact, they are amongst the most abundant materials on Earth. As solar heat capture is so much more efficient than electrical generation, it doesn't require being captured in some fad off land. It can be captured close to its destination. The heat can be captured in the sunny season, stored until the less sunny times, infused when it is needed. Also, with the assistance of electrically efficient heat pumps, stored solar heat can be ramped up in temperature for industrial application, to offset the truly enormous energy demand of industry for heat. More, with a little ingenuity, we can find all sorts of ways of applying such energy. Think about food production in colder climates or dry climates. Store solar heat that can then be used for greenhouses. Add to that all the organic waste from cities. Massive amounts of methane are produced by rotting organic waste. What if warm air from solar heaters flowed through chambers of organic waste on their its way to greenhouses its heating? Warm air is more absorbent, and would absorb the water from the waste, drying it out. This would make the air not only warm, but humid. So, without using fossil fuels or even electricity, one could have greenhouses that are warm and humid enough to grow plants that normally can only grow in more equatorial areas with lush environments. Beyond that, drying out the organic waste would cut short the methane production of the rotting process. Beyond that, it would also produce nutrient rich inorganic material that could be used in the soils of the plants to help the greenhouse even more to grow healthy strong plants. All while while using green not electrically demanding energy. No doubt there are a million other ways non electrical green energy can be utilized by technology to drive our and others quality of life up while at the same time reducing our dependence and demand on the electrical grid. It's good to push for more electrical generation, but we absolutely need to stop restricting ourselves by making it the sole focus of our search for better solutions.

Thing about comments about clean energy is that goalposts always seem to be changing. I remember when electric cars of new generation (Tesla) first came out, people said ''expensive toys, maybe 1000 people will buy one''. Then Tesla said they want to build a million EVs and people said ''there is no market for million electric cars'', now people say price is still not right and range is still not right or that they do not work in all climates. Which may be/is true today, but who knows where we will be in 2030.... Same with clean energy, just 10-15 years ago the discussion was that wind and solar were laughable as resources period, some novelty expensive energy. Now we've moved to ''this will not work as batteries are expensive and we need to store the energy''. As with EVs, well let's see where we are in 2030...

This pattern is also seen in the question of scale. It is the exact same mathematical formula, and it is possible to replicate this improvement in human rights, green energy implementation, health, really everything. If we look with our eyes open, if we remember the the key of "EQUITY". By so many people, companies, and governments starting to work towards a common goal (common goal = search for equity). has given us a period in time of never seen before technological advancement. We need to analyze the influences that are creating this transition towards equity. We do also need to be more holistic, in that everything effects everything else in the universe. Such is its nature. Even going green can either get us closer to equity or divide view points which creates friction that becomes arguable points of view. We must be able to walk in the other side's view. Find commonality, realize you are both reaching for the same core value goal. The thing that is stopping us is ourselves. Our inability to feel what the other side feels. Once we do there arre no limits, because we will all work together. That combination of all those experiences and talent will explode in exponential progress.
