A big problem will be the lack of heat reflected by solar cells back into space. Solar cells create at least 50% more heat than the natural ground. We may heat the very areas where people live inordinately. If these solar cells start to produce cheaper power people will use more of it.
Washers and driers to be set to run between 1 and 5am unless overridden.
I think you forgot one thing : a big chunk of the energies we need is for commercial things like factories, mega kitchens etc which run in daytime. Can someone explain that for me? Why can't we use that for the heavy machines??
Solar power on individual roofs seems like a reasonable goal. Solar farms are absurd. This so called "green" energy is going to require the bull dozing of forests, jungles and farmland at an unprecedented scale. This is going to create hectares of plant and animal habitat destruction. This is not green.
why is the most obvious form of storage never mentioned, compressed air. all you need is an unused warehouse, fill it with storage tanks of various sizes, add one or more compressors and a turbine. (let's not forget windmill are perfect for compressing air that goes directly into sotrage.) put solar panels on the roof and tracking towers with panels on them. during the day electricity is produced on site and off. onsite and excess offsite are used to compress air and store it in the tanks filling them one by one until full. at night or very cloudy days the compressed air is sent through the turbine to produce electricity. very clean, simple, computer controled and you have the cheapest storage possible that outlasts bateries and everything else. if enough of these are built and enough compressed air is stored then some industries could use the compressed air to run things. i read a very old article that at one point appliances or small items ran on compressed air. cars could also run on compressed air. something germany ought ot seriously look into, while also planting many more trees and stop cutting down its forests to greatly reduce run off and flooding while sequesting carbon.
I've been using solar for my primary source of electricity for almost 5 years now, I learned to do more with less!
Storage has always been the problem
Nuclear is a way smaller geographical footprint, has full baseload power potential (no expensive batteries with massive environmental impact), lasts 80+ years per reactor and many orders of magnitude more energy dense. I just don't understand why / how the green renewable minded folks support solar instead of nuclear.
Agreed. It's because we're not dealing with rational people here. Many environmentalists are even against hydro.
Love your video and am glad about the cost of solar being so reduced. I post on eco friendly things as well. They are not all directly related to the video but here are some good planetary suggestions all. Enjoy! Suggestions. 1. Start using soda fountains where you get your personal reusable bottle filled, then ban sodas, juices, and water in plastic bottles. This technology alone would save possibly billions of tons in waste and is already used all over. 2. Go back to using wax paper for wrapping sandwiches as this will eventually go back to nature. Ban plastic sandwich bags. 3. Grocery stores should only be allowed to offer unprinted paper, or back to nature plastic bags for customers that forget their own. 4. Solar, wind, and water based electrical power generation should all be developed before any other less Eco friendly sources would be allowed. 5. Now buildings can be built at any level without using wood, we should convert all housing and other construction to these products, and stop cutting down trees. 6. This is the most important. WE MUST immediately set a population cap on earth and start imposing a one child law on all areas over that amount of density. In short the biggest threat to our existence is the massive consumption of resources to support us all. We need a one child law world wide, that is automatic once this density is reached. It must be enforced.
So I admire your enthusiasm but there's a few problems. You have a bit of an authoritarian approach. Ban this and ban that. I believe that over population is the fundamental cause of all our problems but in free societies you are violating people's rights by demanding one child policies. Better to educate, and to promote family planning and women's rights. Rights are fragile and constantly under attack. Paper bags aren't that great for the environment because they are much heavier. It requires far more trucks to ship and greater storage space. It also puts greater demand on forestry products. Number 4 - these things should all be decided by market forces. Not decided by climate activists. that's a recipe for disaster. Cement used in buildings apparently causes tremendous emissions so wood still might be better. Just my two cents.
It really is time for the world to start sharing resources. Water in abundance but in the wrong places, same with solar power, food, jobs, etc. Come on, world leaders (an oxymoron for most of them, I know).
How about we start with your stuff.
What about flywheel energy storage system(mechanical energy )? Is that also a good alternative??
I've developed a NON-variable clean energy concept that doesn't need wind, solar, hydro, nuclear or fossil. It runs on its own power. I hear a lot of people saying we need new concepts but when I approach a lot of these people, they don't listen. Makes me think they don't really want better energy sources for the world, all they want to do is complain. And FYI, I am not looking for funding, that is not what I need. Anyone out there that can help?
IT MAY BE CHEAP BUT TOTALLY REDUNDANT. SEVERAL REASONS, TOO HEAVY, TOO BULKY, THE RATIO OF OUTPUT IS A JOKE COMPARED TO THE ENERGY IT TAKES TO MAKE ONE WATT OF USABLE POWER. SO MANY WAYS TO IMPROVE THESE EVEN TODAY IN THIS FRED FLINTSTONE ERA OF OBSOLETE TECHNOLOGY. I HAVE SEVERAL IMPROVEMENTS!!
Liquid metal battery sounds better for this use case than Lithium batteries.
Pls reduce back ground music..thanks
Solar energy production is lagging far behind the projections made 10 years ago.
Perhaps solar can be used directly for things like water pumping and desalination plants. Storage is a good thing to a certain extent but really direct use is much more efficient. Reducing demand is even more efficient! Hydrogen looks to me like the genie that needs to come out of the bottle for storage though. Hydrogen can be used for winter heating and can be used for seasonal storage from summer to winter.
Third problem. Need a lot of land. Needs to be further away from the load because of the large amount of land needed.
@Jon Burns This in fact is the only places panels should be placed. Bull dozing forests, jungles, and farmland for hectares of solar panels will result in unprecedented plant and animal habitat destruction. Solar farms are absurd.
There's actually a lot of land to put solar panels on, including on top of houses/buildings/parking lots.
Lithium batteries as a solution is one of the dumbest ideas, we do not have enough lithium to support this. I can't believe that they glossed right over the hydrogen storage. Hydrogen is the most possible solution. Breaking the hydrogen bond takes the same amount of energy as it would produce in a theoretical fuel cell. The problem is that fuel cells aren't good enough yet. We should really be researching into fuel cells more. Because when you use Hydrogen in a fuel cell, the only byproduct is water. Also think about the scaring that the collection of lithium has on the earth.
My opinion? The materials to manufacture solar panels are more toxic and pollute more than fossil fuels ! 🤦🏻♂️
Ah c'mon, you're ruining the narrative with something silly called facts.
How about a global solar grid ? Day in India and evening in US . Production and consumption could even out.
Ha, ha. Total myth. Solar is more expensive than it ever has ever been. It’s like saying cars or cell phones are cheaper than they have ever been. Total marketing Green wash.
@Klaas dykstra Market forces should decide.
@Klaas dykstra : The problem Is that the science of Ecology was turned into the religion of Environmentalism. Religions manipulate believers with dogma and myth. Al Gore went to divinity school .
Total bullshit,let's have a plebiscite on this issue,its too important to let politics make these decisions,the science is not settled,it never was,never will be,beware the great reset!
Batteries are a problem because of Lithium and Cobalt mining and rare Earths for some circuit boards (cell phones, wind turbines). Nextgen Solid State batteries may be a solution (not yet available).
Solid state batteries are invented.. You know... If our future is great then we will use that type of batteries 😉
people need to stop giving solar credits and start focusing learning about how nuclear is the definite winner for energy.
@Robert Jones Agreed. The climate movement is an ideological movement not an environmental movement. Nuclear is emission free, relatively inexpensive and safe. Small footprint too.
Exactly. Green energy is as much a politically driven agenda as anything else. Search SLcd and you'll find plenty of industry experts telling us that nuclear is the way to go. There are also many ex-green energy proponents who have switched their stance to nuclear once they really looked at the economics and overall environmental aspects of nuclear vs. "green" energy.
Lithium ion batteries are not ideal, even though there's been advances. There are liquid batteries that work well as a transitional battery to provide power after sunset. Then at night you use natural gas if it's available. If you tried to store enough power to use all night, using battery it's too much. You're now at a much higher cost than coal. Those other solutions mentioned, which is using the force of gravity works in hilly areas is good. During the day you pump water into an upper reservoir and then when you need the power you release through hydro turbines into a lower reservoir. This adds cost too of course, but I don't think it would be as much as trying to use batteries to store enough power for the night. A great option is to have a balance between solar, wind and natural gas, along with some storage capability. Because both wind and solar are cheap now, the fact that you are creating extra capacity doesn't matter. But in this case wind can help with the needs at night, and if you have windy days, you can use it for power storage as well. Some places are so windy that wind turbines can give all the power you need except for rare days. In these cases a grid with different sources can supplement with power from solar or natural gas when wind is low. The point here is to create a versatile grid, with different sources for energy, and a connected grid so an oversupply from one location can feed an undersupply somewhere else. For that kind of a design, the amount of storage can be kept at a minimum, and that helps to keep cost down.
Your power curve is WAY different than many places of the world. Go to places where it's very hot and it's the middle of the day, when the sun is overhead and moving westward that you have peak demand, because these place, if there is money, have air conditioners that are running non-stop at this time of day. So, totally different model for solar in hot places would be to have them on houses and buildings and generate power at point of consumption. During the hot time of the day, the building is running air conditioning so probably using most of the capacity of the panels mounted on the building. When the air conditioner shuts off after air temp hits the cool mark, then power goes on the grid. And this cycle continues throughout the day, and the air conditioning need in many places is 24 hours a day. Global warming is making it worse. But in general the curve is heavy usage during the day. In the evening when people are using power for other things, the load from air conditioning drops some, and then after the sun has been down for 2 - 3 hours the load from air conditioning drops even more, but still remains. So it looks more like a regular wave form such as a sine wave, cycling through lowest usage at sunrise, then goes up when people get up, then goes up more as more AC is needed, then slows down even when people are using power in the evening because the load from AC is less, to finally dropping down at night time when all load is less. So, no ducks were involved in making that graph.
"Even cheaper than coal" I don't know how cheap coal is in different parts of the world, but in the US coal isn't all that great, and if you look at long term costs, which have to deal with the fact that you're creating environmental nightmare problems for each mine due to the large amonts of waste water that's left over, it's actually pretty expensive. Natural gas on the other hand, in places where it's plentiful is very cheap, and THAT is what solar compares to now, along with wind energy. All those sources of power are cheaper than coal, and they are all cleaner. Natural gas, while being from fossil fuels is almost the same as clean energy, and getting gas/oil out of the ground isn't nearly as bad as coal.
Let's save the planet🙂
Instead of pumping water from lower reservoir to the tank at a higher level , why not relocate this process to an Island or shore area . Once the water is pumped into a tank built at a higher level on pillar on land or in the sea and allow the water to flow on to the turbine below , which can generate electricity and then let the turbine continue its work on the electricity produced . Thus only the initial generation of electricity need the power from out side . Then the 24 x 7 activity of generation of electricity can be done on its own power . The turbine will act as if in hydro electrical generation . If the tank is on the shore , a wide tube extended to the turbine in the sea water will deliver the water on to the turbine there . or Can you allow the electricity produced in this video to pump the water continuously up to the tank 24 x 7 so that day in and day out the existing water can generate electricity continuously .
Solar is useful yes, but the base materials out of which the solar panel is made is silicone which is toxic if not dealt properly. So the questions is how are we going to manage the solar waste in long run .
Your trying to spoil all their fun with facts.
Solar's biggest problem is the loser crew
Solar energy is free its the panels that are assumed cheap today but they could be more cheaper. Just research the materials used to manufacture panels.
I have new concentrated solar power technology. Better than solar towers. Working all the day round, and can store energy. Where can I find an investor or business angel or grant?
Produce solar power at day time and use it at nights for all street lights at night everywhre
Germany has now the ability to incorporate Molten Salt Lithium Nuclear Reactors and phase out wind and solar. Those are polluters whereas the new nuclear technologies are the answer until we can go to fusion reactors, an even more advanced technology.
As each day passes, solar and wind energy are bumping up against their major flaws: nighttime and wind cessation. To sustain our requirements, we must back up those energy forms with new technology nuclear plants. The new technology addresses the problems of existing plants that should be phased out, each, as each new plant is built. The main stumbling block is the usual, politics and current AEC guidelines. When you consider produced carbon as a waste product, the Molten Salt Technology will be cheaper than solar, wind, and natural gas. Natural gas is just a transition away from coal and fuel oil. Why fill the landfills with depleted solar panels?
problem of solar panels are the low efficiency and environmental damages, life doesn’t do well under the shade.
@Kad Gamer roof ok.
Put it on roofs?
no cheap.. cost expensive
Google hydroelectric-, thermoelectric and piezoelectric generators. There are tons of affordable ones available online. Start energy harvesting everywhere.
Thank you for this great video. I think the future of solar energy will highly depend on the integration of thermal energy storage (TES) into solar farms. A technology well known and already integrated into Concentrated Solar Power (CSP) plants. A small problem is that CSP is still expensive when compared to PV panels. Thus, the integration of low-cost PV technology with TES makes perfect sense to increase the share of solar electricity in the electrical demand worldwide.
when you go to the comment section to read some ideas about potential efficient ways to store the energy produced and find all about the 🦆
The claims about Lithium battery farms being the solution of energy storage are completely false. Lithium ion batteries have been specifically engineered over decades to optimize one thing: energy density. This is unimportant for grid level storage as we can make large warehouses full of batteries. These have not been designed for large storage applications, and have proven to be unreliable and prone to spontaneous combustion. By the end 2020, the US has a maximum storage capacity of 1,756 MWh from battery farms. The average daily electricity consumption of the US was over 10,410,000 MWh. So unless we increase our battery storage by about 6,000 times, solar power will not be a viable solution to our energy demands or climate change.
There is No problem with Solar other than lack of enough energy storage to average out the supply fluctuations.... The weather systems seem to run in three day cycles so that indicates a storage capacity of three days use....In areas up to the 45th parallel....above that is not practical.....When the Green New Deal confronts reality, that's when the Solar / Wind deal breaks down....
An even bigger solution is Distributed Generation! Solar Panels do not need to be in farms. Individual panels can be mounted at the point of power consumption. Totally eliminating the very wasteful Grid completely! The only reason this is not taking over is Power Utilities have a lot of political power. And if local generation takes over they no longer exist! We don't need to pay significantly more just so some highly inefficient Corporation can meter and bill for it!
You should make a part 2, how to make a business out of this
Good idea, but that's not our part - maybe the business editors are up for it :)
Could also use the wasted energy to mine crypto currencies which generates income which can be used to expand storage and other operations.
So, how long do Solar Energy panels last, 25 years? Are they recyclable? I believe not at all. Where are we gonna dump all the used-up Solar Panels after they're exhausted? Is it not just like Nuclear? We end up with a load of nasty, toxic waste. Solar may become viable but so much if this is based on Climate modelling that's only based on a max of 200 years of information. Climate Change is a guess, we don't actually know, can't actually prove, that it's happening because of us.
I think the dude charging his phone from a solar panel says it all really. Most small electrical devices run in low voltage, DC. Try running a vacuum cleaner or a washing machine off that. Solar is a fantasy for children, as is wind power. Utter nonsense, don't forget, it's not homes that use the big chunks of electricity, it's factories, hospitals, shopping malls. Climate Change is a guilt trip to control the population.
@Meerkat Hero Same. My 25 Watt solar panel cost me $69 USD. And I had to buy a power bank, to store the energy. But I was impressed with it. I can charge my phone on camping trips. And it doesn't cost me anything for the power.
Climate change is a very broad consent in science. The few who deny it are related to the fossil fuel bussines which is responsible for the climate warming. My solar panels are on the roof for 22 years and still kicking, good for additional 25 years, I hope. The recycling facilities are in place and can be scaled up. In Europe the collection of wast solar panels and a recycling rate of 85% is mandatory by law which all manufacturers have to comply with.
ok, why are you not mentioning that eventually you will run out of mineable resources for lithium ion batteries, not to mention the devastation to the environment that mining of these minerals does... as far as being cheaper... in the U.S. people are relying on subsidies to offset the costs....cheaper for one, costly to all...another point being solar farms are not being limited to less than prime real estate, farmland is being used and prime property for crops and livestock will eventually create a food shortage....i am not against solar energy, i am against using up farmland in this scenario...and passing the costs of ones solar project on to taxpayers...and still Nuclear energy is the cheapest and most productive means of electricity production...
Why is it solar/wind or nothing for these environmentalists? Nuclear is way cheaper, takes up less space and puts out zero greenhouse emissions. Tell me how we stop the sun from getting bigger and hotter every year? That is the big problem for to polar ice caps.
How is recycling of the batteries been addressed? Batteries have an expiration date. Are we now going to have a pit with spent batteries because it’s too expensive to recycle? Same with the solar panels. How are those recycled? 20 year service life then what?
@Richard A spent nuclear fuel is 100% recyclable already with todays technology. The same can't be said about solar panels...
@Richard A Cadmium and lead, but that's besides the point. For every ton of nuclear waste (which is securely stored according to extremely strict laws) there are 147,000 tons of solar panels that are destined for the landfill because recycling is cost prohibitive. That is on a kwh basis -- forget that a modern reactor is 1/10,000 the size of a solar field with the same output and that a reactor has an 80+ year lifespan while solar arrays are 30 years max. Finally, the environmental impact of lithium, cobalt, silver, cadmium mining combined far, far outstrips that of uranium.
@Noyour Business Toxic Chemicals in Solar Panels
@Richard A Cadmium and lead are two examples. But that is besides the point, Richard. Proper waste disposal methodologies and technologies must be implemented for them. You are arguing against someone who supports solar power and gives suggested solutions to greatly improve battery storage capability at reduced land area.
@Musa Fawundu *Spent solar panels remain toxic too* What substances are toxic in solar panels? Name them.
Germany got fucked over big time
Solar has a huge cost to the environment. Do you know how much energy is used to mine the minerals required to make solar panels? Do you know the amount of damage to the environment the chemicals that are used to process and make these panels make? Far more than what oil, gas, or coal does. Yes, oil, gas, and coal produces Co2. But Co2 is plant food. These specialized mining operations are eco killers. Arsenic, cadmium telluride, hexafluoroethane, lead, and polyvinyl fluoride are just a few of the dirty little secrets solar panel zombies don't tell you about.
Do these batteries have a lifespan of about 10 years ?
The comment that solar is cheaper than fossil fuels is a lie. The problem is the production and waist of the equipment and it's impact on the planet. The over all cost difference between renewables and oil, coal and gas is extreme, renewables being more expensive, that's why less than 20% of our power is produced from them. Also, renewables have a life span of less than 20 years and as forecasted will have to be replaced twice, even before we achieve them suppling 23% of our power uses. Lets not forget; the largest supplier of Lithium is China.
My job is engineering of power plants, an important part of it is energy yield simulations and financial modeling. I do not agree with your opinion. Almost always, new solar PV has the upper hand, economical wise. LCOE's of USD 20/MWh and much less cannot be achived by new fossil fuel powered plants, solar PV can and some PV power plant projects will even be in the range of USD 10/MWh. Your opinion on the lifespan is also far away from reality, e.g. the solar PV module lifespan is 30 years, at least. China is the largest supplier of rare earth elements, they are not big in lithium. Australia and Chile produce much more lithium carbonate. I see a lot of opinion in your comment and little knowledge only.
Need a lot battery's
US sell patents, China employ thousands in manufacturing and the whole thing works because the European taxpayer pays for € 300 per MWh renewable electricity. See, no problem 🙄
@Meerkat Hero 300 €/MWh is the price at which the French Energy regulatory body has approved for a photovoltaic + hydrogen power project in French Guyana this year.
The actual prices are in the range of € 50/MWh in gloomy Germany for solar PV and less than € 20/ MWh in Portugal. Might be good to update your "database" as your prices are already history for a long time.
Lithium sulphate battery is better than ion battery
Anywhere that the uptake in renewables is high, the Energy Operators charge high rates / fees / surcharges in order to keep their revenue. Here they are bring in the ability to charge homes with solar to be able to export to the grid. Absolute Nonsense!
That hydro battery idea is super cool
I love use Avasva Solutions for that issue.
Maybe i didnt know about it. How about for a while shut down coal plants when solar energy production at peak and use coal energy when solar energy at its low... Trying to learn btw
Would work to a certain extend, however, it is a very limited option to run solar PV and coal power plants in the same system. A coal power plant incinerate coal in a very hughe combustion chamber, a water-steam cycle gets heated up, the water evaporates and drives a turbine which drives a generator. It takes many hours, normaly a few days, to bring that chamber on temperature, to start the steam cycle and to synchronize the generator with the grid. During such a long time many solar peaks will happen and be gone again before the coal power plant is ready to start production. Timing is crucial and it is not possible with such a inert system, like a coal fired power plant, to be ready when needed. Also, it is difficult to limit the fuel input under a certain treshold as the heat chamber would get too "cold" in some areas, damp would condensate on the steel surface and, as a consequence, the steel would corrode. Technical, coal power plants a not capable to backup solar, only if the solar and wind share is very low coal can coexist. The next issue with coal is an economical. The utilization rate of the power plant is of utmost importance for the price of electricity (we call it LCOE) generated in a coal power plant. If the utilization rates goes down the LCOE goes up exponential. This menas, a coal power plant that backups a system with a high share of wind and solar would be uneconomic. These type of plant is meant to run 24/7, if that is not possible it gets uneconomic plus technical problems which would require to keep the coal power plant "hot", even if it is not needed for most of the time. Backups that work are gas turbines, as they have a cold start time in the range of minutes to a few hours and the cost of electricity is mainly driven by the fuel price and not by the utilization factor. Other options are pumped hydro and other storage technologies like hydrogen (most promissing technology for the long term and highe scale storage) and battery storage systems for very fast reacting grid support.
it's always the same bs, companies want to keep charging us what they want, get solar!
Solar is cheap, but every thing else is expenses via batteries and inverters
The cost of both is dropping quickly.
Nuclear Gen 4 is better. And there are a lot more innovations coming to nuclear that will make it even better. Solar will be great to supplement it.
Unfortunately solar cells soon become scrap, lots of scrap.
Annoying, Annoying music! Anyone else noticed that DW has been going downhill in terms of content and quality?
To what extent are we going downhill in terms of content and quality, can you explain that?
I think that looks nothing like a duck
Why don't use the hydrogen cell to replace lithium cell
That doesn't look like a duck!
I worry about the attachments (rubber rings circling the nail) which can cause leaks on the roof in time with say, asphalt roofing shingles. When the roof needs to be replaced, what happens to your solar kit sitting on top of your roof?
Fred, that's one of several reasons you would want to seek out a reputable installer who's likely to be around long enough to make good on their warranty. As to roof replacement, yes, and a legitimate installer will evaluate the status of your current shingles before advising solar installation because otherwise there's an expense to removing and then reattaching the panels.
Well whats about flywheel storage?
What is going to happen to the solar waste? Who will take responsibility for the disposal? Since its going to be of huge volume storage and recycling is going to be enormous! Any thought in this regard ?
We need a law for the mandatory collection and recycling of used solar modules, like the one in Europe. In Europe they have solar module recycling facilities in place because the solar industriy must collect and recycle 85% by law.
I stayed for the ducks
Link solar power around earth to solve night time so, no down time
I think underground spring system's should be studied as an option for energy storage.
Solar is cheaper? its about $30,000 for a very modest sized home, If you know how to install it yourself. if you dont have said skill set, expect to pay around $60,000 to $80,000. Mind you that is not including maintanece costs... I am certain that if you have an extra $30,000-$80,000 just laying around, it will pay itself off about the time you are ready to die so there is that.
Did you ever built a solar PV? Maybe 20 years ago, the prices you mention indicate that? I assume you did not built any solar in the past past 2 years, because the prices you mention are so far away from todays reality like Pluto is away from the Sun.
The upfront cost for flow batteries is greater however the long term net price to maintain a flow battery system is lower because flow batteries can last up to 25 years compared to lithium ion batteries that can only last 7 or so years. The amount of energy that they can store does not drop off over time like a lithium battery either.
Why have energy prices risen in Germany so dramatically over the last few years?
The cost of electricity in Germany is one of the highest in the world. Over the past two decades, the price has increased due to a number of surcharges, taxes, and grid fees.
How about the deserts or places that can’t be used as a place for it
In order to determine the effects solar projects may have on biodiversity, it is very important to survey the land to evaluate potential environmental impacts on wildlife and habitats.
If we replace it one day and only solar panels and wind I wonder how they will get rid of the power plants without a chenobal like event
The absolute solution is everyone should just get solar for their houses and stay away from the power grid. The power grid is stupid when it comes to solar...people should just produce their own electricity. That way the government cant charge you hundreds every month, an you have money to actually save and be able to gain. Also wouldnt it be good to no longer deal with power outages?
@Alan May no duh?
Without batteries, solar is basically useless.
question: for the world to go x% more than fossil fuels, were are you going to put the cells, most roof are full and most negative land has a solar farm, were do you put them?
I don't know where you live, must be the solar vally. If I have a look around most roofs are empty in most of the countries worldwide, same for unused land.
About 100 giant solar panel factories must be built by 2025 for the world to "defossilize" its energy supply by 2035. Read more here: www.dw.com/en/how-many-solar-panels-do-we-need-to-save-the-climate/a-56020809
china is an international crime and human rights abuse organization. They can make anything cheap when they steal all the ip and enslave their population. It's not impressive.
On Amazon a solar panel is still about $1 a watt in 2021 so I'm not sure if that number is for wholesale
The solution is simple. Don't bye on Amazon if you are looking for a good price. On Amazon you may get expensive, single, solar modules only. For a solar system you need all components, not only a single panel. Complete solar systems are not available on Amazon.
The answer for large-scale power generation lies not with solar panels but thermo-solar power plants.
If you look at the numbers, its really not that cheap - unless you get it up the butt per kwh like CA and a few other communist states in the US.
Battery technology and multilayered solar will solve all of these issues in the next five years. We’ll reach a tipping point on renewables soon. It’s already cost effective In a five year period to get panels and a power wall.
The panels, are too practical in form, future styles, like the clear gloss glass form, could probably be more universal in texturing around infistructure.
Electric costs will double to pay for the same TAXES !!! that fuel has. Government will Not let you drive without paying up!
Molten salts Concentrated Solar production is the real deal just heat up those molten salts during the day and in the evening the heat up the water into steam,,,,
With the global dimming" effect at 55%, why waste energy and resources in the creation of a system that only works in daylight hours and is only about, at most, 45% efficient? Isn't that called WILLFUL BLINDNESS?
AND Electric costs will double to pay for the same Taxes that fuel has. Government will Not let you drive without paying up!
Dont you guys know about one world one solar grid...??
its not cheap, it's heavily subsidized
6:19 oh not this again. It was never even built it's such a stupid idea....
“Dirty power plants” nuclear plants are more efficient and cleaner than solar. The manufacturing of solar is so dirty it makes coal look like a sterile surface... not to mention lithium batteries lol they’re horrible! Building an elevated lake is a lot easier and cleaner than LI batteries
@fewstrzf fewstrzf I didn’t say there was (as long as it’s done properly). I’m saying that these wastes could be reused to further quality of life and provide energy for centuries.
@Nelly Nell no you dont have to do anything about the waste, radioactive materials are and should be under ground. Earths core and mantle is heated by radioactive decay for example, there is not a problem in burying radioactive waste.
@fewstrzf fewstrzf they have a new way of getting rid of the radioactive carbon waste from it. They create man made diamonds with it. They become batteries with permanent charges.
exactly and there is nothing wrong with burying the nuclear waste undergroud. Only problem would be if it infested ground water otherwise it's good thing to bury it underground it came from there after all.
For me the best idea would be huge compressed air containers and then run turbines when needed. If there are even compressed air cars, something stationary is much easier.
But solar is still very expensive because of battery storage 🤷 Battery dies after some cycle usage 🤷 am personally working on a better alternative for this problem 😊
i'am curious what alternative way of storage you are working on
Well that's cool at list I have solar power in my house because China made it cheap 😊😊😊
