With UV resistant backcoating it should last at least 25 years probably much longer, but we just don't know yet. And with glas back it should last indefinitely until the cells deteriorate enough to make it economically worth it to be replaced. Which is a quite long time at 0.5% deterioration per year.

Thank you so much everyone for watching! There are a thousand more things I would’ve loved to say and include in this video. There are so many clarifications and footnotes to include. I had an entire moment talking about the benefits of nuclear but as with everything else, it detracted too much from the point I was trying to make. A large part of my struggle making this was figuring out what the point of this was. How can I simplify such a complicated scope of a topic into something that is easy to understand, correct, informative, and entertaining enough for people to stick around? It was hard. I hope I’ve done that. Of course there are huge problems surrounding materials, toxicity, and emissions when it comes to the production of solar tech and lithium ion batteries. But these are just that… problems. We can solve them!! We WILL solve them!! I’m trying to inspire the right people who will help us discover new solutions. I don’t anticipate changing anyone’s mind if they don’t believe in climate change. I’m hoping well reasoned folks who ARE interested in a better future see this and realize the simple fundamental realities of what’s POSSIBLE before getting lost in the weeds of the technical issues preventing us from getting there. I want to never EVER again hear the phrase “solar is great but it’ll never beat coal”. No. I refuse to accept that. We can do this.

The visualization for nuclear assumes we continue to use the same type of reactors which are only able to use about 0.5% of mined uranium. Breeder reactors are able to use the 238 isotope, which enables them to use ALL of that uranium, including the "waste" from current plants. The waste alone is about a 1,000 year energy supply without mining a single additional ounce. Breeder reactors can also consume thorium which is 4x more common than uranium. All told, the Earth's minable supply of fertile nuclear material can last longer than the predicted lifespan of the sun. But of course, the limitation on solar was never the sun, but the materials and waste from manufacturing the panels and the storage. Solar is doable, but nuclear will do it with at least an order of magnitude less of land, material, waste, and it can be ramped up faster.

[@evanbarkman5786]

That's kinda what I thought (although I didn't remember the details on how much of it we have), not to mention, by the time we'd have any issues with available nuclear material, we'd likely be able to bring megatons to Earth from asteroids and/or the moon if we really needed it. I'm not opposed to solar, and maybe we'll be able to make solar power plausible some day, but I think if we want to actually reduce CO2 emissions, nuclear will do it faster, cheaper and with less side effects on the environment, all while giving us more energy for our civilizations to work with, which would increase the standard of living for people. Then if we needed to someday transition into Solar or direct Fusion we could do that.

[@kyle18934]

Nuclear produces so much energy for very little impact environmentally. I don't know how to convince people that nuclear is a lot safer today than when it first began. The idea of radiation poisoning is horrifying. You don't know you are going to die because of that contaminated breath two minutes ago. I believe nuclear is the way we need to go, I just don't know how to convince the world it's safer than the coal we use now

[@JETZcorp]

@@kyle18934 Comparing it to coal is an easy one if people will listen at all to statistics. Forgetting about climate change for a moment, the direct deaths from particulate and heavy-metal pollution caused by coal are approximately 1 million per year. Depending on who you believe about Chernobyl, that's 1 Chernobyl a month or 1 Chernobyl an hour. If they've ever worried about mercury in fish, coal is where the largest portion of that mercury came from. Here's a fun one. Because coal is fundamentally a rock, it's got traces of other materials in it (hence the Mercury and arsenic etc). But there's also some uranium and thorium in there. Some loads of coal have more energy in uranium and thorium, than they do in the coal itself. If coal plants were regulated like nuclear, the NRC would emergency-shutdown all of them overnight for the radioactive material emissions alone.

[@jakkonexus1166]

...and you didnt even mentioned how safe they are and how promising small modular reactor are. Good luck with sun and wind with shifting climates like we're having right now, worse and worse each year. Nuclear mainly + Renewables. That's the only way to salvation till (and if) fusion will be viable.

[@JETZcorp]

@@jakkonexus1166 Frankly I'm not sure what fusion is supposed to solve. Thorium costs negative money, and even with the current inefficient cycle, fuel represents about 5% of the cost for fission. Fusion power would probably require a ton of super high energy tritium and deuterium, which are famously hard to contain (they do fun things like pass through solid steel). If the design of the fusion plant itself proves to be considerably cheaper, then we've got something. But there's no way to know if that's going to be the case, and several cheeky leaky isotopes tell me it probably won't be. I think fission is where it's gonna be at for a very long time.

so produce chemicals to produce clean energy, but the chemicals that get produced still ruin the air quality, makes sense

[@Project2457official]

Why are we trying to marginally decrease coal emissions when we can shut down coal and move away from fossil fuels?

[@SPCv4]

​@@Project2457official Because we can't simply "shut down coal" and we are dealing with billions and billions of tons of greenhouse gases from coal. Even a 0.01% decrease is still a reduction of millions of tons. We can't just shut down coal because we've already built a trillion dollars worth of coal reserves, mining equipment, dedicated transportation infrastructure (trains, trucks, etc), coal power plants, and the specialized labor that does all the mining, driving, and running of the plants themselves. The trillion dollars of renewable energy infrastructure just isn't there yet, it needs time and investment. Even if we all universally agreed to get rid of fossil fuels right now we'd still need a decade or more to build all of the assets that coal and such already has, not to mention the actual tearing down of the existing coal assets. Large swaths of the country where coal is the majority or the only power option would be in perpetual blackout until renewable energy got built in their area, which again could take a decade. I know it sucks but this shit takes time, the fossil fuels industry has had 150 years to build up their assets, renewables has had 30. We *are* shutting down coal and moving away from fossil fuels, it just takes decades to do so.

[@kliajesal4592]

@@Project2457official Nobody takes into consideration the economic impact that shutting down coal has. Hundreds of thousands of people work in coal mines and would have nothing left if coal were to suddenly shut down. You're talking about something on the scale of genocide to put a sudden halt to an industry for the sake of putting a small dent into air pollution. Even if the US were to completely shut down all coal production and coal power plants, you still have China and India to consider and they're not going anywhere any time soon.

[@Project2457official]

@@kliajesal4592 Not a small dent. Most emissions come from energy production, especially for electricity. You're buying into the fossil fuel lobbies narratives. We can slowly but steadily transition away from coal especially.

[@salernolake]

As a retired engineer who worked his entire 40 year career in the energy sector, I applaud your message at the end of video - we need more engineers. The biggest challenge young engineers will face is the safe storage of the large quantities of energy that have to be harvested when the sun is available, to cover when the sun isn't. To wrap your head around the magnitude of energy to be stored, consider that a typical 500 kV line from a power plant delivers enough energy to launch a Statue of Liberty into Low Earth Orbit, roughly every 20 minutes.

Hi Neil, HS senior trying to decide. Which do you recommend, Mechanical or Electrical Engineering?

[@brentonsmith3901]

Construction major here! I love the concept of solar panels everywhere, on paper it sounds like a fantastic idea. But in execution there are three glaring problems: Solar panels have laughably short lifespans, farms are bad for ecosystems, and the reason why solar farms are built. As it currently stands, good industrial panels only last for maybe 25 years, and that's assuming that the panel isn't defective or doesn't get damaged during its deployment. Outside of their metal components, panels are not able to by recycled, and their manufacturing process is far from green. In order to build a solar farm over a large area, you have to displace all of the local wildlife. Additionally, farms in SoCal and Arizona generate so much heat above them that flocks of birds have been known to spontaneously combust while flying over. Oddly enough, solar farms are more efficient in northern climates where you are able to use bifacial panels thanks to lush ground coverings and snow. This is really interesting because it shows how few people understand how solar works, because the vast majority of farms are constructed in deserts where you lose anywhere from 8-15% efficiency than if you constructed a farm in a lush and colder environment. Lastly, solar farms are built for one reason only: money. Land owners have discovered that you can make a lot of money by selling solar power and get huge subsidies and tax breaks for constructing them. Solar has an incredibly fast turnaround for making profit, and again, it's just a 25 year scheme for the landowners as they wait to find even more profitable investments. I love solar on paper. I love solar as a supplemental energy source in urban environments, such as over parking lots or on buildings. But it's not the solution. With how delicate they are and how unclean the manufacturing process and end of life plan, it's literally like patching an oil spill with gold foil. Just like how electric cars aren't the environmental solution (trains are), our best hope for the future, until we achieve true fusion, is nuclear. It is the cleanest, safest, and most efficient energy source we have. And the sensationalism of nuclear accidents has generated unwarranted fear. Chernobyl was the result of Soviet lies. Fukushima (which did not kill a single person) was the result of a for-profit company actively choosing to not follow safety measures recommended to them in the 90's. The real reason why we haven't gone fully nuclear in this country is because it isn't profitable in the short term. Because of all the measures we take to ensure that nuclear plants are 100% safe, they are incredibly expensive for investors. But the environmental and energy returns are completely worth it. We may not have a solution for permanent nuclear waste storage, but I'll take carefully monitored temporary storage any day over landfills full of millions of dead panels.

[@kraziecatclady]

I'm working on my bachelor's in Geosciences with a concentration on natural resources and conservation. You forgot to mention the resources required to create solar panels are also limited. Just because solar energy is very abundant doesn't mean the materials needed to create a panel are. Food for thought. it takes 4 tons of coal (and also additional wood charcoal often harvested illegally from rainforests and sold to China) to create 1 ton of solar grade silicon ore. That doesn't even include the energy required to slice the ore into wafers, make the other components, ship the panels to their destinations, and set them up. A good portion of the increased pollution generated by factories in China comes from making cheap electronics. A similar ore (with a higher purity) is used in the majority of semiconductors inside of computer chips for just about all of our modern electronics. Some panels contain chemicals such as cadmium and lead which can leech into the soil contaminating the land and waterways although most of them don't have a high enough concentration to be a real hazard. Note I said most, not all and as you mentioned, the panels degrade over time which means more of their components will leech chemicals into the soil as they begin to decompose regardless if it is while they are still in use or once they are disposed of however they decide to tackle that issue. That's why they are considered hazardous waste. Then remember all the talk about heat. Too much heat destroys electronics. Some types of solar farms can require up to a million gallons of water to keep the panels clean enough to absorb solar energy and cool enough to prevent damage. Many of those farms are as he said... in the desert. That kind of water isn't available in the desert, so it has to be taken from another location. Another bad part of placing them in the desert is that events such as sandstorms can cause microabrasions on the panels which will reduce their overall efficiency over a fairly short period of time. All of that water needed for some systems makes me wonder if solar panels that are meant to be a solution might actually be responsible for more frequent droughts and forest fires than people realize (although poor land management and lack of controlled burns are also contributing to forest fires in some areas but that's a separate subject). As for Nuclear, I agree it is one of the best solutions we have so far, the problem is that outdated policies prevent us from getting the full use out of fuel sources in America. France and other countries are doing way better with updating their policies to match modern technology. As you mentioned, advancements in technology not only make Nuclear safer than it has ever been, but also make it possible to safely extract more energy from the fuel sources than we could in the past. This means that if the policies were updated, we could actually use rods that were considered "spent" but are still stored on site at many Nuclear power plants as disposal has always been a heated debate. The other problem with Nuclear is that most people don't really understand it and are afraid because they hear the horror stories of Chernobyl, Fukushima, and weaponized Nuclear devices such as Fat Man, Little Boy, and the Tsar Bomba. Truth is more people have died or become severely ill from complications associated with contaminants released into the environment from coal plants than have from all the Nuclear incidents in the world combined, but it more spread out by time which makes it harder to identify than the quicker identification from a Nuclear incident being tied to a much small location and timeframe. Funny part about electric cars is where you also have to consider the materials necessary to create a new car vs. using what has already been manufactured and also the consideration of the source that is charging the electric car. Plugging one in at your home supposedly uses approximately 30% more power than a normal US household, so you can expect a 30% cost increase on your power bill (which might still be cheaper than gas depending on where you live). If saving money is the goal, you could possibly break even if the costs come down on electric vehicles, but if saving the planet is the goal, people also need to consider what kind of plant is powering their house or apartment. My apartment is powered by a coal plant. That means if I bought an electric vehicle, I'd be using coal to power my vehicle instead of gasoline. Is that any cleaner? I honestly do not know, but it certainly isn't as clean as people would like to believe. As for trains, that might work for a lot of countries, but unfortunately America is large and spread out. They are great for big cities, but the majority of people living in America that use cars on a daily basis live in suburban areas that were intentionally built to optimize personal vehicle use and to make public transportation inconvenient. Look into it, cul de sacs make neighborhoods a nightmare for busses to travel and slow down cars to make it safer for children who might be outside playing. Designing neighborhoods the way they are in America has reduced vehicular accidents in neighborhoods, but made them really difficult to navigate on foot or via public transportation. This seriously needs to be addressed if we want to cut back on car ownership and promote public transportation. Some areas still won't be able to rely on public transportation regardless though when you consider how much farmland we have, farmers, and people who work in those places. I went a few weeks earlier this year without a car and it was pretty rough (someone drove into me totaling my car out). I live in an industrialized area more designed for truckers than foot traffic. I can't tell you how many places I walked where I was close to fast moving trucks and had no sidewalk. I came home pelted with tiny rocks that flew off the asphalt when the trucks drove past me. My white socks became grey and nasty. There's no bus routes nearby and the closest train station is probably about 15 miles away. There's no space for a bike, nothing. I ended up getting a rental for part of the time being. I also spent some time in a few other places during this time including my boyfriend's place out of state and had similar issues near his apartment. Inner cities would benefit a lot from better public transportation, but outside of the cities, something else should be considered. I really like the idea of shared vehicles if self driving cars become a more available option. A vehicle would come get you kind of like uber, but when not in use, it would be parked charging or something until someone else requests a car at which point, it would go get them. The hard part about that idea though is ownership. Americans like to own their own stuff and the thought that it isn't theirs could dissuade some people... Anyways I think I've typed enough. Oh yeah, one more thing, most power grid systems regardless of the type of power generation they use are only designed to run optimally for approximately 30 years. Yes, most of our power plants are severely out of date by this standard (and this makes upgrading Nuclear plants that much more important as many of them are closer to 50 years without renovations despite the 30 year optimization I mentioned which is also why some hazards occur to Nuclear power plants in particular). This doesn't mean a power plant needs to be taken out of commission at the 30 year mark, but that the efficiency and safety measures may have advanced during that time and the power plants should have renovations done after 30 years to modernize the equipment or risk hazards associated with worn out materials. This applies to all power plants, coal, hydro, natural gas, solar, wind, as well as nuclear. Just an interesting thing to note when it is mentioned that solar panels only last 30 years and that is only provided that nothing else damages them prior to that 30 year mark. I'd imagine hurricanes in Florida have probably ruined many solar panels before that 30 year mark. You should also look into how solar panels are wired. Did you know that a single shadow can cut efficiency across an entire panel because the wafers are wired as a series circuit? This is to prevent inverters from becoming overloaded within the panel. If they were wired in parallel, inverters would get destroyed by too much power getting sent through them during peak production hours. It's the wafers in the panel that are wired in this manner. Some of the other portions are wired in parallel (depending on the specific set up), but the smaller sections do not afford the space for inverters that can handle higher levels of power. Some whole home power grids are wired in series depending on the type of inverter that is being used within the home. Inverters change DC power to AC power (for anyone else reading this that doesn't know what a power inverter is).

[@jaquigreenlees]

I have also heard that solar panels take a drop in efficiency as soon as they are installed, you need to clean them a day after installation to regain the loss. There was a vertical axis hydro power system being designed that would work in areas with a 4 knot current. They actually floated in the water, anchored in position. They lose power generation if used in salt water when the tide changes, at about 10 to 15 minutes every 6 hours. This type of hydro electric system doesn't have the costs and risks of building a dam to store a water buffer for energy production but has almost the same maintenance costs. There is a 360 odd acre plot available locally that has an existing dam and permit for a 1 kw/h power plant, they built the dam, created the reservoir but never completed the construction. Of course, currently it is 100% off-grid, not even cell service on the properties, it is adjacent to a park so development is strictly controlled / limited.

@@realGBx64 Oh, I agree completely. If you dig deeper, there are ties related to increased automotive sales and making it harder for people below the poverty level to move into suburban areas because at one point, most impoverished families could not afford vehicles at all and living in the suburbs without a vehicle is very inconvenient. Now, most families in America can afford vehicles, but impoverished families cannot afford decent vehicles and the excessive maintenance required to keep their vehicles on the road eats away at the savings they could be using to make their situation better. Older vehicles not only require more repairs but generally also have higher insurance rates because they don't qualify for as many rebates as newer vehicles do or may not have the same safety features such as day running lights and airbags. They are also less fuel efficient. Even hybrids lose fuel efficiency over time from a combination of wear and tear and technological improvements. Now the push is to get people to move on to electric vehicles, but not everyone can afford them yet and if additional fees are imposed on people still driving fossil fuel vehicles, it will be another charge that impoverished people incur that the more wealthy people are able to get out of, but people aren't putting much thought into that, just like they aren't considering the power sources charging those vehicles. Everything is a mess when it comes to the environment and policy. They should be focusing on policies that are designed to make new neighborhoods work better with public transportation/foot traffic or the companies designing the neighborhoods incur a fee, but instead people want to focus on forcing everyone to buy an electric vehicle and possibly start paying a "mileage tax." 🤷‍♀️

And he still couldn't be totally honest about solar, even intentionally glossing over nuclear - the superior option. Cost is incredibly relevant, because people won't mine lithium, nickel, and other precious metals and minerals for free, nor will they refine them for free, they won't transport them for free, they won't make the factories and refineries or even the vehicles for free, nor should they. The scale he's calling for is colossal, and the cost would be astronomical. No way he spent 3 years researching this and didn't realize going full solar is pure fantasy. Doesn't matter if he tries to belittle the cost argument, because cost IS relevant. I also don't appreciate him dodging the cost argument by asking what the cost would be to not go solar. That has some real forced labor camp undertones to it, and I don't know about y'all, but as a libertarian (who'd never shoot up a super expensive solar panel, because why would I?), I'm VERY against forced labor camps, and violations of human rights in general. He's had 3 years to write that script. Let's hear how we produce these billions of solar panels and force them on the world WITHOUT violating human rights.

@@Gottaculat I think you're completely missing the point. Obviously cost is a huge thing to consider, but wasn't a focus of the message I was trying to convey. My entire point is that there's a huge amount of solar energy available that we're simply not using. The "how" we use it was less important to me because it's constantly evolving. Technology is constantly developing better and more efficienty ways to harness solar energy. I had an entire love letter written about Nuclear energy but it detracted from the message too much so I cut it. Did you not watch the part where I said "how many solar panels could power the world" isn't a good way of thinking? It's not about the solar panels!!! It's about free energy! Also, I didn't take 3 years to write this video. I just started writing it 3 years ago.

Love the ending! I would add consideration of Kennedy's famous words "We choose to go to the moon in this decade and do the other things not because they are easy, but because they are hard. Because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we’re willing to accept. One we are unwilling to postpone." The context for these words (the whole speech) is worth reading of course. But it echos your parting sentiment. There will always be those who do not want change, for myriad reasons. Who point out the difficulties. Their perspective and the things they point are are important, because they reveal the obstacles that we need to overcome. But it should not stop us, rather it should help to define the tactics we use to meet our strategic goals of adopting renewable energies. One of these key obstacles is of course storage, and I was pleased that you embraced a wide concept for power storage. Additionally, a reasonable future for renewable power will need to incorporate decentralization of power generation and storage - which means overcoming a lot of barriers that are not in the engineering realm, rather are economic and political.

As an engineer who has designed solar facilities before, I have a few comments. 1) 1 megawatt of capacity in solar =/= 1 megawatt of capacity in coal/nuclear/etc. Solar gets 1 megawatt during noon on the equator on the fall/spring equinox. The local solar facility we have here is a 5.5 MW facility. It puts out 7.5GWh a year, sounds like a lot, it breaks down into 860 kw on average. That's nothing. And that's at the solar panels, before you have to convert it 2) you minimize the monumental challenge of transmission/ and transforming of energy. Since solar takes up so much space, even after you harness your tiny little 20%, that get divided further because it is at an unusable (for the grid), dc voltage. Inverters and transformers are incredibly inefficient, and its really expensive and inefficient to have them put out decent sine waves. And since these proposed solar farms are being put in the middle of nowhere you have to use massive transmission lines (that use expensive copper that has to still be mined) to get it to where it is used. This is also super inefficient. To add to this, virtually all this inefficiency isn't just disappearing into the void, its bled off as heat, the thing that solar is proposed to reduce (through a reduction in greenhouse gasses).

[@timogul]

I don't think he was seriously proposing massive facilities in the middle of nowhere, that was just to give a visual aid to how much _total_ space is needed for such a system. It mostly proposed putting the solar panels on roofs and parking lots, which puts them literally on top of their biggest customers, much lower transmission loss than from the nearest coal plant.

[@cranberrysauce61]

other issue that isn't talked about is the production costs, maintenance costs, and degradation of the solar cells in which causes them to be even less efficient. the resource costs are so often ignored in the talks of having large scale solar projects. while it was from a couple years ago read a paper talking about the cost of production for solar panels and for a solar panel to go carbon neutral it would take the panel around 10-15 years, and im not sure that took into account the decreased output as the panel ages. while going to complete reliance on solar is basically a pipe dream, im still in favor of increasing the number of smart solar installations to cut down on the reliance of coal and oil.

[@alexanderburns9026]

Ironically enough I am a petroleum engineer who care about the eventual switch to clean energy. The biggest problem with today's solar panels is cost to performance. As it currently stands solar is just too in efficient, with the cost of make, up keep, and transmission of the panels and energy for our grid. The best we can do right now is invest in research to build more efficient, cheaper to make solar panels. Until then we should keep using smart coal and natural power plants that capture the Co2 after burning.

[@timogul]

@@alexanderburns9026 No, getting started on solar right now is the way to go. It will get cheaper and more efficient the more customers there are for it. There's no reason to stick with coal or natural gas as a primary fuel source, unless you are in the fossil fuels sector.

[@ThePolysyllabist]

He didn't address the material requirments though, which is what actually holds back widespread adoption. Converting just the US to solar would require 100% of global silver mining for the next 99 years. And that's just the US, which produces a fraction of the world's co2 (China produces nearly half). It's an argument that completley misses the real issue.

[@lareolanKFP]

@@ThePolysyllabist That's the whole point of Wren's request for people to become engineers so they could solve problems. It's not like current solar tech is at it's best, as Wren said, it's only 20% efficient in capturing light, that means 80% of light that hits the panel just heats it up or reflects off of it and does no work. This is something that has a LOT of room for improvement! The same goes for Lithium Ion batteries, they are great right now, but they do require some pretty rare and hard to find elements, but they are also not the pinnacle of energy storage as there's many new designs for solid state batteries being researched right now, some of them using elements that are abundant everywhere (like Silicon) requiring no rare elements in their construction. All of these designs last longer than LI batteries and have much higher power to volume ratios, but they currently lack funding to refine them into usable mass-production models. So yes, materials are a problem right now, if we just tried to use current tech as is. If we just invest in developing green technologies, however, those material problems will go away pretty quickly if the money that is currently going to fight against electrification (lobbying, campaigning, advertising, etc...) were invested into coming up with solutions on how to make it work.

[@Daniel_Parke]

@@ThePolysyllabist With any topic there could be thousands of nuances, do you want a video that covers it all? Because that would take literal hours. Could you share where you got those figures from? Seems very convenient how round and easy those numbers are to work with, that would be a nice coincidence and lining up of the data for presentation. Second, you can apply those arguments to preserving the current way of things, as all of modern engineering requires precious earth metals. So your not making an argument, your just pointing out the negatives. So should we stop using ICE engines, high spec turbines or mobile phones because of the resource requirements? Better yet, let's just reverse the industrial age because it uses materials that we had to redesign supply chains for. I mean it would take over a hundred years to implement this so called steam engine, so why bother? Let's just continue cooking over fires whilst freezing to death occasionally in winter. That's essentially your argument but with a modern spin. Humanity always strives to adapt and overcome the greatest challenges, not give up at the first sign of resistance. Just because there are challenges to adopting sustainable energy does not mean we should do it, nor does realising it will be tough mean you can just pretend the damage from fossil fuels doesn't need to stop. There are many ways to harvest solar energy outside PV, yet you only mention the materials required for silicon wafer based panels. This is because you don't actually have an interest in resolving the issue, and are instead arguing a point you view as societal/political/tribal. Otherwise your point is literally mundane and irrelevant, as you have completely missed the bigger picture, and are essentially complaining about a speck of dust in a sandy desert. As per usual it's a big topic with many nuances, solar is just one tiny piece of the puzzle.

But theres a fair chance we could recover quickly... My question would be how do we keep the Nuclear power plants safe? What if the EMP is from a "solar storm" that lasts months? .. Its a little tin hat I know.. But that is just a natural cause.. The thing about our civilization is that our advancement is largely dependant on our ability to consume and store electrical energy..

The biggest issue right now is the materials needed to produce a few of these things, like to make one 1000lb electric car battery it takes 500 THOUSAND pounds of land to actually get enough PURE industry standard lithium using a massive fuel guzzling miner, lithium isn't that common and can be difficult and costly to make, not to mention that most of this stuff has to be transported on Trucks, Aircrafts and Cars that are using fossil fuels, not to mention other materials that would be used the make the frame of cars and more, so for NOW electric cars can be more of a burden to make than standard petroleum cars, the only cars i see going anywhere are Toyotas Hydrogen cars which are awesome and I'd highly recommend looking into it. This kinda repeats itself with solar panels and others like that, the infrastructure has to be built for this to actually work and that itself can cause huge amounts of damage, i'm not saying to just carry on mining natural recourses but i'm also not saying stop cause its used in everything from mechanical things to farming, there needs to be a more sound solution than purely solar and electric energy, the two that seem to have good potential overall would be Nuclear and Hydrogen power. There's never going to be a world where we can remove entirely these fossil fuels being burnt, the main issue i see isn't necessarily the UK, Norway and many other countries in Europe which keep getting smashed with policies to reduce carbon emissions even further But more places like China which still uses huge amounts of coal in factories and contributes the most to pollution, the US still comes in at second for creating the most pollution but then you have other factors like developing countries creating incredible amounts very quickly due to them developing their country and/or poor living conditions. TL/DR: Electric vehicles are cool but still create massive amounts of pollution while creating them, Hydrogen and Nuclear seem like solid options but can be expensive, and it's down to a few countries to really cut down on pollution as others are being hit with policies that wont make any considerable impacts on global pollution, No emissions are in its infancy stages and for now can be more costly

You cannot stop mining because nothing can be made without materials, but if we're majorly electric and renewable, at least we won't be suffocating the planet.
