If we start there--covering every roof with solar panels, and then cover most car parking lots with solar, we'll have enough solar energy.

in the US there are about 2 billion parking spaces. I think it is a perfect match to place PV-panels above these parking spaces. If a parking space is 10 m2 (and per parking space there is an additional 10 m2 on access road), that would make an area of 40.000 km2 of area. depending on surrounding buildings and or trees, there would still be a huge area suitable. When driving through Arizona, it really struck me that all cars on the parkinglot of a shoppingmall were located around a tree hoping to get a sliver of shade.

Everybody that had installations to light their gardens, or have a remote controlled barrier on solar energy are rapidly dealing with dying lights and have to manually open their fences (a more complicated operation than if they had a non-motorized fence to begin with)

This is crazy. The Building Regulations should be amended immediately to include the mandatory installation of solar panels on all new buildings and whenever roofs are renewed. By installing the panels integral with the roof covering the extra cost of the panels would be partially offset by savings in roof tiles.

While slapping solar on every roof and car park sounds like a good start, the issue is that not all roofs are angled towards the sun or receive shading due to trees or nearby buildings.

Large industrial farms, which make up the vast majority of farm land, won’t adopt the idea as the panels prevent tractors and combines from working.

Solar flux-related mortality - mortality resulting from the burning/singeing effects of exposure to concentrated sunlight. The nature and magnitude of impacts to bird populations and communities is generally related to location, size, and technology.

Nice video, its really heartwarming to see these systems gaining attention. A bit over-the top dramatic editing for my taste, but guess it works for a wider audience.

One place that could be a really good place for a solar farm: the Chernobyl Exclusion Zone. The residual amounts of radiation there would not bother either PV panels or wind turbines. The latitude is fairly high, but that wouldn't mean necessitate much more panel area, mainly just more land area, which will be really cheap there. The PV panels would be angled more to the ground, so would cast substantial shadows. The wind turbines could be sited so that the PV panel shadows mostly line up with the turbines' shadows. The composite shadows could be good places to put energy storage, although those could probably go just about anywhere. Some computer simulations would be needed to work out the best combinations to optimize the system as a whole, including what kind of tracking to use for the PV part, and the design of the wind turbines. The income from energy generation in the Zone could help with the cost of clearing the entire area of natural structures and vegetative overgrowth. The sooner this can be done, the better, as it will mean the potential for spreading of radioactive substances can be reduced sooner.

Frodaddy09, Yes I did assume you meant stand alone home generation. However what you suggest is how electrical generation started, with small power plants feeding a small area. It soon became obvious that forming a grid and interconnecting was far better, cheaper and more reliable. Another flaw is that you can't run even small island grids with renewables, they are not suited. The only reason that we have so much renewables connected to grid sis that there is also conventional generators which keep the grid stable . Remove them and the grid would simply go out of frequency control and trip.

I would like to have more information on some issues, particularly, cooling the panels with bodies of water means warming the body of water in turn. On a large scale this might have adverse impacts. And secondly where are we going to store excess power for the night? With hydropower it would be feasible to have dual reservoirs and use excess day energy to pump water in the higher reservoir and let hydro generate power during nights. But the biggest issue is still energy storage with PV.

Many thanks Skystrider. I keep trying to tell them all that our behavior towards the environment is what needs to change. How's this for a behavior change: "profit = protecting and enriching the environment, and sharing the sustenance that it provides to all of us". I'm afraid that creating solar and wind energy infrastructures will double the damages we have already done to the environment, and these new infrastructures will, themselves, cause more damage to the environment as we use them. This may be the last nail in our collective coffin. The new profit model will create millions of new jobs that will come under the heading "Caretakers of the environment". Caretakers will earn higher wages than most other workers. There will be thousands of specialized subdivisions each dealing with different aspects of the rebuild of our environment i.e., human population size, the beneficial use of waste that we presently put into air, water and ground. We must also clean up the waste we have put into the environment. I believe that this new profit model will virtually put an end to homelessness, and it will reverse man-made climate change.

Thank you and I agree. Recently I've been hearing about ideas around HDI (human development index) replacing GDP. If measurables such as environment, pollution, education, equality, lack of social problems such as homelessness and suffering, and much more, were included in an HDI measurement of every country... Then those who only focus on GDP would likely do poorly in HDI and if we value HDI higher, then trade and dollar values could reflect that and incentivize HDI instead of GDP. Endless $$$ growth is highly unlikely esp in 70 yrs when world population decline will be well under way, and aging population replacing working population well before that... So if we measure ourselves differently, we can still be successful even if GDP is going down while HDI goes up.

It might be harmless to people, but probably not to electronics.So, it is not a crazy idea that any government would add the possibility of target the beam to another places.

You're better off utilizing the silicon and aluminium deposits present in the lunar regolith to build your space based solar cells. Plus the moon is located higher in the gravity well, meaning that you would expend minimal energy getting the materials to a GSO position.

The major issue with Solar is electricity storage The issue with solar is that we dont control the output. its the available sunlight that controls output. So if electricity demands are high & sun light is low => it creates a problem. We need much better & large scale electricity storage solutions which can bridge this demand. Also we need to expand nuclear energy. Nuclear is very safe contrary to popular beliefs.

Morocco is investing in the kind of solar energy where mirrors heats a “tower” full of salt (and water) to extreme temperatures. Then a steam turbine generator produces the electricity. The salt remains hot during the night (although the electric output obviously decreases). Some European nations have signed deals with Morocco to import electricity. I think even the UK will import electricity… the losses are obvious high for transferring electricity that distance. But in reality I would suppose the electricity actually produced in Morocco will be consumed in nations like Spain and France, and the electricity the British will use will be what is produced in Spain and France through other means. Although I think you are wrong. Usually the price of technology drops the more who consume it, when also more start to produce it. Manufacturing is rationalized, costs of production and transportation decreases per unit, and patents expire. Where I live we have a different problem though: The panels doesn’t get much sunlight when the sun is hardly over the horizon during, and >1m snow covers everything. 😊 While we also use more electricity during winter. So wind is a better option. And the old hydraulic power can balance it. Still people have started mounting solar panels on their roofs. They can sell electricity they don’t consume to the major electricity producers. You can even get the electricity producers to pay some of the costs of the panels. But then you have to pay for the electricity more or less just like before and doesn’t earn much from the electricity you eventually sell. Non-electric solar panels to directly heat water has been relatively common for a while though. I have a long pice of a black hose left over from a building project. That I just lay on the ground for the sun to shine on it summertime. And have the water run through it before it enters the actual heater. It likely saves some watts of electricity on water heating costs when doing my dishes. 😄

During wartime any standalone source of electricity that is tied to the grid or can be converted to the grid easily will be a valuable resource as well as ensuring sources of electricity cannot just be eliminated easily.

Hi. Well done! "Thinking outside the box" and constructive use of various niche generation opportunities is excellent, however you underestimate the inherent difficulties and risks in some cases. Solar panels floating at sea isn't something I'd invest in, firstly because the solar panels will be attacked by salt corrosion and quickly fail. Second, you mention "waves" as a problem just once, but waves are actually the main trouble. Not only will they saturate the panels in seconds, but just one bad storm could consign the whole solar array to Davy Jones's locker. This also applies to inland lakes and estuaries. As all surfers know, storms out at sea, even if they never reach land, can still generate 4 meter on-shore waves. This idea is a money loser. Fitting solar panels around farms is a good idea, but only practical around crops that don't require mega-machinery to plant or harvest. The panels will hinder evaporation of water, but condensation will collect underneath, which may be a problem. Your most useful idea is putting solar panels over car parks. The electricity can charge the cars directly, without the efficiency losses of converting DC to AC (for the grid), then back to DC to charge the car. They would also cool the sidewalks, turn open streets into person-friendly malls, and best of all, no-one need return to a stinking hot car. This idea could also help solve the tragic problem of children dying because their ignorant parents left them locked in the car for "five minutes", but got distracted, and remembered them a whole two hours later. The SPCA will love it too. Thanks for your hard work. Cheers, P.R.

In the mean time we can require that all homes and businesses install solar panels on their roofs with a simple and inexpensive grid tie inverter. The average home consumes at least 100 watts/hour on standby power. This can easily be generated at home and fed into the home's grid with two 100watt solar panels ($200), plus a 1000watt grid tie inverter ($100). This will allow each home to generate the standby power the consume saving at least 800watts each day that they don't have to draw off the city grid. Multiply this by say, 1,000,000 homes and you get at least 800 Mega watts that can be saved from the city grid each day.

"Whats the best way to build solar pannels without loosing much needed space?" Not sure if it was one of your documentaries or one of arte ..., but there are currently research efforts been made with solar pannels in a vertical orientation(here called solar fences // im Lot zur Erde stehend) as it seems to be even more efficient in conjunction with agricultural fields. The problem being with horizontal or slightly angeled panels, the water is not spread evenly and one would need additional watering mechanisms which would eat into the energy balance. What was new to me and never considered, was that there could be nearly a greenhouse effect for tomatos and other plants which otherwise would maybe get even too much sun. So it is not only about what is the best overall solution, but rather what is the best solution depending on the plant you want to harvest. I would expect depending on how you construct a solarpanel, you could direct rainwater also downbelow instead only towards the edges. Can farmers in europe get subsedies to establish such systems? The other buzzword currently in agriculture is regenerative farming, could these concepts be combined? I'd need more information on the longterm effects of floating solar pannels to its direct environment before taking a stance on those. One thing they deffinetly arent't and that is pretty. So those of us who at times look for some untouched nature wont like it to see every inch of inland lakes covered in solar pannels. Maybe that too should be factored in within our need for energy. Same argument surely would count for solar pannels within agricultur. Maybe we need somthing like exclusion zones. Like we could have in a 7 kilometer radius around cities these concepts established first, which would also make sense in terms where this would come in handy where to use it, but have your more rural communities protected from these, but keep them as more nature orientated and recreational without all these. I can see though the appeal to protect water from evaporation for areas where scarcity becomes an issue. The solar pannels in space may have a secondary use which i would want to be seen debated should it be feasable as i currently conceptualize them. Depending on how many of those there would be, we would microwave parts of the atmophere and that can't be all good, depending on who or what is flying threw it or at what on earth it is aimed at. Besides the technological challanges to protect them from solar winds, getting them up there and cosntructed and suchlike. I am not against them, but there definetlly needs to be international debate and regulation, soo good thing you made them a topic :) Costs for infrastructure i always see as an investment in the future and therefor i find myself rather agreeing with bold concepts are these than in the past with investments into say military, though that didn't age well(looking at you Putin -_-)

Yes definitely

The first idea already fails, because the panels are not angled. When it comes to solar energy, every % of energy loss counts. The further away you are from the ideal angle the more extreme the energy loss is. Sure you can add the automatic rotation, but that is an insane amount of extra cost, on top of the already expensive frame system that carries 2x less panels, but requires the same amount of materials. On top of that, you are adding a lot of new maintenance and making the basic maintenance way harder. The increase in €, $ per wattage is insane. You literally lose on everything with this design. Less land for crops, less area for solarpanels. In the end, rather thsn keeping it seperate, you are compiling the two and greatly increasing the costs. It is simply not practical. Just like the solar roads idea, just a little less extreme. Solar energy is all about making a profit as fast as possible. Even with goverment support, in some places that is around 10 to 12 years. Now double the costs and you get around 20 to 24 years. If I'm not mistaken, then inverters are changed out every 10 to 15 years. So in extreme conditions you have to change them twice. Which means that 20 to 24 years is closer to 23 to 27 years. Problem with that is the fact that solarpanels have a lifespan of 25 years or so and they lose a lot of efficency by the end of their life cycle. In other words, this doesn't seem to be that profitable. I'm sure they have some way to make it more profitable, but then again solar panel roads was pretty popular for some time. Unless they can make it a lot cheaper (nowadays when panels are up in price again) and effective, they are just overpriced shade for a few types of crops.

Nuclear should be part of a future carbon-free grid. It is a very good "base load" power plant while being carbon-free and consistent. But there are obstacles: 1) Takes billions of dollars and 5 to 10 years of construction time on top of years to even get a permit to start with its dozens of local feasibility studies, eco studies & community hearings -- investors are skittish about these things as they add a lot of uncontrollable risk 2) People don't want to live within 2 counties of nuclear plant if at all. The nuclear plant can affect house property values which people fight tooth & nail to preserve. Some don't even want solar farms or wind farms near them either! 3) A nuclear plant's nameplate areal power density is probably not much more than a large solar farm. Because nuclear plants require a large restricted "keep-out" radius of land around the plant which decreases its areal power density. 4) Solar photovoltaic costs have plummeted 90% since 2010 and is now the cheapest levelized cost of energy (LCOE). This has unexpectedly disrupted the energy markets of even its sibling technologies like thermal solar and concentrated solar power (CSP). The prices are still on a downward trend with upcoming tech that can increase photovoltaic efficiency another 25% to 50% (Perovskites TF, quantum dots). Last but not least: 5) Nuclear promulgates a centralized grid architecture Can't be overstated that nuclear still represents the traditional *centralized* grid which, by its inherent design, is not as robust for modern-day challenges. In the event of natural, man-made, or terrorist disasters, a centralized power plant can be taken out or disconnected leaving large parts of the grid the plant serviced to be un-powered for days or weeks. With climate change, natural disasters are increasing in frequency and intensity. A gigawatt nuclear power plant services millions of homes. In the modern world, we've seen the robustness of de-centralized networks from things like cryptocurrency and torrent file sharing. Even the internet itself is a form of de-centralization. Solar power provides a pathway to such a de-centralized distributed network where power is generated *and* consumed locally at the source -- and there's nothing more local than consuming power right from the roof. This applies to residences, commercial, and industrial. Unlike any other power source, solar integrates very well into dense urban landscapes with its abundant commercial, industrial, and residential rooftop spaces and parking lots. Combine with upcoming grid-scale battery storage, an urban county will be able to be electrically self-sufficient for most of the year. You could drive by a 1/2 or 1-megawatt solar array installed in a local college campus and barely bat and eye at it. Even without grid-scale battery storage, a region could be running some 50% to 75% from solar allowing its base load natural gas power plants to throttle back to idle during much of the daytime. Moreover, the distributed nature of rooftop solar spreads out the load on the transmission & distribution links of an aging grid infrastructure. Because a new powerful power plant like a gigawatt nuclear facility is going to put a big load on smaller part of the grid where its power flows out from.

But the aluminum frame is easy to recycle is 33% or more of the weight of each panel. (2) Since solar panel prices have dropped a staggering 90% since 2010 and continuing to decline, the addition of a small recycle surcharge on each panel to support recycling is not out of the question. Or include a small "deposit" fee that de-incentivizes dumping panels into the land fill because each panel has $5+ redeemable only when delivered to a certified electronics recycling facility -- similar to the 5-cents deposit aluminum cans and plastic bottles.

I understand if this was done in Singapore where land is limited. But it's impractical to do this in California where there is plenty of open desert. Just put it in the desert and plant some low water ground cover under to keep it cool.

The only issue I see with solar panels is the dust. We won't get the most of solar energy if the panels are covered in dust. And we need water to wash the dust. It is a common problem at a solar farm in India. The farm invited controversy when it used underground water to clean it's panels, water that could have gone for irrigation and as water supply to nearby settlementa. It isn't as simple as placing solar panels everywhere. You need to make sure the panels are working at peak efficiency

Google the duck bill curve, a major problem with mass introduction of solar PV. As the energy generated reduces in the evening, conventional generators have to ramp up to meet demand which has its own challenges. Battery storage is essential.

I think a way more important issue is how panels are manufactured and how they are recycled, Solar panels are great but they need to be easily manufactured using readily available materials and have a reliable recycling system.

Hi Evan, we have touched on this topic in the following video: kzread.info/dash/bejne/d4uKlsdtZZbfaLw.html - let us know your thoughts in the comment section 🌍

I remember many decades ago, reading that one of the Scandinavian countries were putting solar panels on the sides of roads and in the medians of roads. Is there a reason we can't put them along train tracks and along highways. How many thousands of miles would that be? How much electricity would that generate? Quite a few million barrels of oil, I'd say.

Busy roads produce nasty, sticky, oily, _waterproof_ residue that would necessitate very regular cleaning. I'd expect to see output fall by 10-20% per month between cleanings in a highway setting. You'd also need to ensure that the panels' coating can resist chemical corrosion from the hydrocarbons (and the solvents used to wash them off).

@@westasleep OH ! You mean like the coatings on our lungs, from all the dino petrol gas byproducts. ha ha ha. Ok, your explanation makes a lot of sense. Maybe if they did it, they could coat them with self cleaning glass, you know the type the talked so much about - how it was all supposed to be put on all our buildings, but now you never hear anything about it. I did see people are putting circular vertical wind turbines by where trains run to spin when the trains go by and the puff of wind displaced by the trains spins the windmills.

I will say here in the Mojave Desert, there is TOO MUCH sun for most plants. Too much heat, way too dry, too windy, and too high of an altitude, so less atmosphere to block sunlight - way brighter up here. Really, most people could not imagine how hot, dry, and sunny it gets here, and it goes on for hundreds or even thousands of miles. Imagine 3 months with temps at or over 100 degrees every day with no clouds. And this is the cooler part of the Mojave, near the mountains and ocean of Los Angeles. Here, most plants grow better in at least partial shade, or mostly shade, or full shade. So this is a good idea for desert locations.

Sounds brilliant place to start tbh.

How do we deal with the heat produced because of the lower albedo of the solar panels? Will this drastically increase temperature?

If you look at a thermal camera image of a roof with solar panels, the panels are cooler than the surrounding roof. Which makes sense. The light that falls on the roof and gets absorbed just heats it up, while about 20-25% of the light absorbed by the solar panels gets carried away as electricity, leaving less to be radiated as heat.

Great Innovation, am also planning if have the capital to apply agrivoltaic in our small area in Philippines. Your studies and research educate and help us a lot

One thing people forget, it's currently only a maximum of 28% efficency... Imagine 50-80%? It'd be the equivalent of having a panel in full sun making less than a more effective one in the shade. With the potential to even run cooler.

Nice video, DW you are raising the bar with every video. Nice background music too!!!

Where can we put them? I would ask how do we produce them?

Thats really cool to see 🤙 I also wonder why we don't build solar panels above or on the side of roads, if you make them movable with tracks it would remain acessable for Firefighters, towing services, cranes and so on in case of emergency. Roads would not heat up as much as far as the wear of the tar is concerned, and drivers would be happy too.

put the panels close to existing transmission lines. minimize the transmission distance, because that is a big part of the cost and profit. on top of all buildings in urban centers especially, where the power is most needed.

Pastures as well, especially in hot climates.

They should build solar panels near the areas that mine for solar panel materials.

Here in the Southwest US, they are putting utility-scale solar installations (hundred of projects that are 2,000 to 70,000 acres of solar panels in size) on undisturbed wildland and wildlife habitats with little to no mitigation or oversight. Solar is becoming a growing cause of habitat loss and a threat to biodiversity. It seems people are quickly making all the same mistakes with solar they have with every other type of energy extraction.

Agrivoltaic can help revive farmlands that have gone out of business because conditions got too hot or too dry. The farmer can earn extra income from the solar panels.

Fantastic; two birds with one stone...we need to move fast to protect what earth we have left and to enhance biodiversity.

Very informative. But the background music is TOO loud.

clean energy clean water The biggest idea I am trying to express is tunneling aqueducts from the coast, in this case the west coast of the USA inland to feed combination geothermal power and sea water desalination plants. The idea seems to be so big that no one has considered it possible but I believe it is not only possible but it is necessary. For over a century the fossil water contained in aquifers has been pumped out to feed agriculture, industry and municipal water needs. The natural water cycle cant refill fossil water deposits that were filled 10,000 years ago when the glaciers melted after the last ice age. Without refilling these aquifers there is not much of a future for the region of the United states. As a result ground levels in some areas of the San Joaquin Valley have subsided by more than 30 feet. Similar fossil water depletion is happening in other regions all around the world. TBM and tunneling technology has matured and further developments in the industry are poised to speed up the tunneling process and it's these tunnels that are the only way to move large volumes of water from the ocean inland. The water is moved inland to areas where it can be desalinated in geothermal plants producing clean water and power. In many cases the water will recharge surface reservoirs where it will be used first to make more hydro power before being released into rivers and canal systems. It's very important however to not stop tunneling at these first stops but to continue several legs until the water has traveled from the ocean under mountain ranges to interior states. Along the way water will flow down grade through tunnels and rise in geothermal loops to fill mountain top pumped hydro batteries several times before eventually recharging several major aquifers. What I am proposing is essentially reversing the flow of the Colorado River Compact. Bringing water from the coast of California first to mountaintop reservoirs then to the deserts of Nevada and Arizona and on to Utah, New Mexico, Colorado and Wyoming. This big idea looks past any individual city or states problems and looks at the whole and by using first principles identifies the actual problem and only solution.
