Is green hydrogen the answer to the climate crisis? | DW Documentary

Green hydrogen produces zero emissions and many believe it holds the key to limiting global warming. So is it the big hope for the future or a multi-billion euro mistake?
Many believe green hydrogen could provide a miracle solution for countries around the world seeking to decarbonize their economies. But the technology is still in its infancy. Generating sufficient quantities of green hydrogen would require a lot more renewable energy than is currently available. Right now, almost all hydrogen is produced using natural gas in a process that generates large amounts of carbon dioxide. Green hydrogen, by contrast, is climate neutral. It's derived using renewable energy. The principle itself is not new but has, at yet, only found limited usage.
Engineers at the German Aerospace Center are now working with the world's largest artificial sun to try to produce hydrogen without any electricity at all, using only light. If they can succeed, it would allow large-scale production of this valuable gas in countries that receive a lot of sunshine. Hydrogen is already being used as a fuel for buses, trains and cars, with hydrogen-powered planes due to follow shortly. Hydrogen is even the fuel of choice for space rockets, and German submarines glide along almost in silence thanks to hydrogen fuel cells. Manufacturers of airplanes, trucks, and even steel are investing millions in the technology, hoping that hydrogen will be the go-to fuel of a climate-neutral future. But critics warn of major challenges ahead, saying billions stand to be wasted.

... CO2 at 0.04% is a 2,500th part of the atmosphere. That means to warm the climate by just 1"C carbon dioxide molecules must capture 2,500"C of heat energy. That is impossible. It also breaks the fundamental laws of thermodynamics. Methane at 0.00017% is a 600,000th of the atmosphere so it's even more impossible. However, the climate is changing. This is because of deliberate geoengineering programmes, in particular ozone thinning away from the poles. Though largely unreported ozone thinning effect is directly observable, this summer you can see a unnaturally bright sun just as we did last year. Under these conditions the pain felt when looking at the sun is not only from the increase in visible light but the much larger increase in infrared. (Look up at the sky and you will see a range of geoengineering operations in progress, these include chemtrail induced cloud or hazing, ripple patterns caused by HAARP installations, bizarre and unnatural cloud formations). Climate change is a programme to force change in accordance with the implementation of Agenda 21 /2030. Current events demonstrate this transition is well underway and will involve massive population cull through injected nanotech (re transhumanist programme). Agenda 21 also sees the permanent loss of all property rights with the introduction of universal basic income (ref NESARA/GESARA) and has/is being promoted by The World Economic Forum. 'You will own nothing and you will be happy' WEF In a depopulated world the surviving brainwashed and controlled population will be confined to mega cities. Carbon limits will be used to restrict consumption and liberty. Meanwhile the re-greened wilderness will be the exclusive playground of the ultra rich elite posing as conservationists. The CO2 hoax amounts to the theft of the world and the enslavement of humanity by a parasitic few. Welcome to the future! _________ I have included a debunking of 'accumulated heat' as it is so often used to explain how trace elements, so called 'greenhouse gasses', can warm the planet. Accumulated heat whilst sounding a reasonable explanation of how heat can build up is rather nothing more than gobbledygook. In fact it shows those using such arguments do not even understand what heat is. When we measure temperature we are measuring the heat energy a thing is losing. In short heat is a measurement of flow, the transfer of heat energy and this will always be in the direction towards the colder. For this reason a thing can never 'accumulate heat' in the way those advocating CO2 climate change describe. The temperature of a body is the measure of heat output, it can never be greater than the measure of heat input. Output = input. When a thing is warmed it is heated to an equivalent of the heat input. If this input is not maintained it will cool. Those that propose that heat can build up to be hotter than the total measure of heat input at a given time either do not understand what heat is or are being deliberately misleading. To illustrate, an object being heated by a flame can never become hotter than that flame, it's temperature cannot rise inexorably to the temperature of the sun for instance. Heat cannot be accumulated. When we think about it common sense tells us this must be the case. NASA and even Nobel Prize winning physicists have expounded 'accumulated heat' as the explanation how CO2 is able to warm the atmosphere. They claim that over hundreds of years CO2 has captured heat energy and this heat has 'accumulated' to produce a serious warming effect. As I have just explained, this is totally impossible and fundamentally violates all the laws of thermodynamics. That respected scientists should support such uneducated, unthinking nonsense is disturbing and only reflects that in terms of being able to think clearly about a subject they have no facility or inclination. These are the Dark Ages of science. Belief has outweighed logic or any critical thought. It tells us that we should not unquestioningly accept anything we are told, that experts can be fools. (NB: be aware of attempts to discard thermodynamics by talking about biology. Eg. 'It only takes a drop of arsenic to kill a person.' This would be somewhat desperate, muddled thinking. Clearly biological processes based on the reaction of a cell are not the same as the laws of physics/thermodynamics).

When considering the risk of hydrogen explosions, it is well worth pointing out that LNG (liquid natural gas) and propane are stored and shipped everywhere, and are more dangerous because, unlike hydrogen, they can pool on the ground from a leak before exploding. (A large LNG tanker could theoretically detonate with the force of a small nuclear weapon and would look like the famous Beirut explosion.) I still remember a video of a white misty fog spreading over the ground from a train carrying propane that derailed. That cloud became a massive fireball. If it was hydrogen, it would have quickly risen away.

The inefficiency of the green hydrogen cycle is an insurmountable obstacle for it being used for anything other than niche applications where batteries can't work. Also, using only surplus electricity from renewable sources to create hydrogen means that the costly equipment is unproductive as it sits idle for a lot of the time, making it even more expensive. Storing surplus electricity in a battery is over 90% efficient, and capital costs are also much lower - hydrogen will never compete without a massive breakthrough in efficiency. Just because it is technically possible doesn't mean it will ever be economically realistic.

[@Jamie-Z]

It depends on the objective. If you want zero emissions then it is the only option. Electricity sounds great but its uses are extremely limited and most people who live in cities where it is most useful cannot park in the drive to charge up normally from normal coal based power stations. Electric has range issues etc. as well and short lifespan which makes them a waste problem which means they are the exact opposite of green. The best option for hydrogen is to build solar plants in the Sahara (like the one already in Morocco) but no one wants to extend the Arab power. The infrastucture of the oil industry could easily be changed to hydrogen.

[@MDP1702]

@@Jamie-Z *most people who live in cities where it is most useful cannot park in the drive to charge up normally* These people need to park their car somewhere at night no? So it is just a matter of deploying low level 2 chargers to regular streets so people can use them at night. Besides that you need to ask yourself what these cars are used for: travelling to work? charge at work. Go to the shop: charge at the shop. ... Essentially there are more then enough possibilities to charge, however they need to still be rolled out. And if you really have no other choice, fast charging is available too. *Electric has range issues* The current hydrogen cars have a marginally better range than several EV's, who sometimes are much cheaper than those hydrogen cars. Besides you'll need quite some hydrogen refueling stations, which are very expensive. For that same price you can place around 30 fast chargers, that you can disperse over a wider area, meaning less time lost going to a station vs hydrogen. And if you have a car that can go 500km, that would be more than fine enough for almost anyone, considering you can't really drive further than that in 3-4 even when constantly driving at a speed of 130km/h (which is the highest limit in a lot of countries/regions). And after every 3-4 hours of continuous driving you are advised to take a 15-20m minute rest anyway, during that time you can also go to the bathroom, eat or drink something, stretch your legs, just shut your eyes, ... In regards to trucks/semi, 800km seems to be a good range considering you'd be able to drive that range in around 9 hours at the usually top speed of 90km/h. Beyond that you'd exceed lawfull time limits in the EU and can be fined for driving too long. And realistically most trucks won't drive non stop for 9 hours at the max speed. Tesla semi have a claimed 800km range fully loaded, if that is correct, there really isn't a reason EV trucks aren't a good option for regular trucking. Only for multiple driver trucking would you need hydrogens range (and even then, what is losing 30-60min at a fast charger considering the cost savings driving on battery power?). *as well and short lifespan* What lifespan are you talking about? The batteries? Current Tesla batteries already are expected to last beyond the lifetime of most ICE cars, this also goes for several other EV parts (like the motors). So I don't really see what you are pointing at. *which makes them a waste problem* Not really, all EV parts are recyclable, even the battery (several companies already achieved a 95%+ recycling rate). *The infrastucture of the oil industry could easily be changed to hydrogen.* I don't agree with that, it is quite a different infrastructure you'll need. Only general things like docks for ships wouldn't need (much) changing.

@@CL-gj9mf *The "inefficiency of the green hydrogen" is the same than the fuels actually used in our cars* With the difference that these fossil fuels are just taken from underground, they are useless when not used (though obviously better not to use if we have better alternatives), whereas hydrogen is created with the energy we alreade have generated and can use directly with for example batteries, thus the energy loss from hydrogen use is a net loss, the energy loss from fossil fuels not. I suggest you look at the EROI of fossil fuels and hydrogen before making such a stupid statement. *but you don't talk about the pollution induced by the big batteries of your "so good electric cars" with 90% efficiency* That is made up for in a couple years. Furthermore with high rate recycling (which several companies can already do), we can keep reusing these battery materials afterwards, seriously reducing any polluting impact batteries have. *The price to pay in CO2 freed in the atmosphere, to extract these rare earths is too high* You realise hydrogen use will also create more co2 pollution? First by the need of installing 3 times the necessary renewable capacity and secondly the fuel cell materials etc will also need extracting. *And extracting these rare earths are done with petroleum* Because they obviously still need to be electrified. Do you think a hydrogen system will only use material that was mined by non-petroleum means? *No more petroleum, no more big batteries!!!* 'No more petroleum, no more hydrogen'. There you have it. In fact currently: 'no more petroleum, no more civilization', just great. However if we can electrify everything we can, including everything in the manufacturing of batteries, the 'no more petroleum, no more batteries' stick wouldn't be correct anymore.

Hydrogen will/should only be used where electrification by direct use or batteries isn't possible, like in shipping, airplanes, industrial applications (for example steel production and industry that requires high temperatures), ... *Petroleum isn't useless, it store CO2 out of the air we breath, and out from the water we live in...* I clearly meant useless in terms of energetic value to us, not in terms of carbon storage. This was completely in regards to your comment that hydrogen is as efficient as fossil fuels, which is actually really bad for hydrogen since we need to put all that energy in it first, we don't need to this with fossil fuels. * it doesn't exist* Yeah, it does. Several small companies already are capable of recycling lithium batteries at 95%+ efficiency. The main reason these are new pretty small companies is because they were founded with the vision of recycling EV batteries, before EV batteries the recycling market for lithium batteries just was too small to be interesting. *We aren't ready for fully recycling plastics* Completely different thing. Just because we can't fully recycle one thing, doesn't mean we can't recycle a completely different thing. *Fuel cells already exists* So do batteries. And their recycling. *If you choose others solutions you choose to engage war with China for the control of minerals and rare earths ressources* Most battery resources are not in China. *You can't electrified industrial moving engine* Depends what you understand under it. They even already electrified enormous mining vehicles that transport the mined substance, though for now it is still situational. And there also are already electric tractors for agricultural use if I am not mistaken. *So we will have to use methane produced from agricultural residues* While I like the idea, it isn't practical. I personally thought about that too, but the only way to do this is to have cattle sit in well isolated barns and having a system to get the methane from that air, doable but not really profitable and definitely not for mass scale use in industry, more like personal use of the farmers or surrounding area at best. *ITER is the final research step from 80 years of climbing efforts* ITER is not the final research step unfortunately. All ITER is meant to do is show we can get more energy out of the reaction than we put in and do so at a large enough rate to be able to produce enough electricity in another plant. Even after that we'll need to see if it will be commercially viable, building actual testplants that can produce electricity, ... And for now there still is no certainty ITER will do what it is meant to do. Yes, normally it should, but we can't know for sure. Even fusion scientist say that we don't need to expect any real electricity generation from fusion reactors within the next 30-40 years, even if ITER is succesfull. By that time we need to have fully electrified our civilization already.

Pretty much, Hydrogen is essential an energy storage medium for applications that can't easily use electrical energy directly. (aka eliminating toxic batteries, space shuttles, etc).

A very informative film. I didn't know about the work on directly converting sunlight to hydrogen, without using hydrolysis which is inevitably less efficient than using the electricity directly. I agree with the woman who says 17:30 hydrogen is not suitable for light passenger vehicles at the moment. It may stay with heavy trucks for several decades in most countries. However there are some places where hydrogen for light passenger vehicles may make more sense earlier. Perhaps Japan and Korea, if they aggressively convert their economies to hydrogen with the help of imports, may find it economical to use hydrogen for light vehicles and shorter trips earlier than most countries. And the work on hybrid drive trains is also interesting.

[@patrickstarrfish4526]

“Green” hydrogen is a sham. First, unless it is coming from Nuclear power, there will never be enough solar or wind to create hydrogen in scale. Second is the explosive nature of hydrogen, in addition to storage volume due to poor energy density. A nuclear reactor produces enough energy to fuel an aircraft carrier for 20 years. A short haul plane using propeller drive could be powered directly from a small nuclear reactor. Germany can’t even stay warm this winter, going green without nuclear power is impossible. The “green agenda “ and transition is fine, but the bias against carbon-free nuclear power makes no sense.

[@hp2084]

Hydrogen can never be replacement for fossil fuel because of energy density. Hydrogen Under ambient conditions, a cubic metre of hydrogen provides some 3 kWh, equivalent to 0.003 kWh per litre. Pressurised hydrogen contains about 0.5 kWh/litre at 200 bar, 1.1 kWh/litre at 500 bar and 1.4 kWh/litre at 700 bar.

In Alberta, Canada has the largest production of tar sands, one of the dirtiest fuels, polluting its rivers, soil, and air! Canada's ecological footprint pre capita was graded at 8.17, just below the U.S. at 8.22 (2016), which is higher than European nations. Some small oil-producing nations like Kuwait and UAE produce far more greenhouse gases because of their refineries. But the problem is about more than just who is producing the most greenhouse gases or who is producing the most green energy; it also involves who is consuming the most products made with those greenhouse gases, who is most exploiting Earth's resources faster than they can be renewed? Now, the figures given were for per capita, but if we look at national rankings without regard to population and other factors such as China and the U.S. being major exporters, then those rankings change. But one could well argue that per capita ratings are a more accurate and fair measure. In that regard, Canada is on par with the U.S., Oman, Mongolia, and Australia, the only five in the world which require more than 6.7 global hectares per capita. ECOLOGICAL FOOTPRINT PER PERSON: The Ecological Footprint per person is a nation's total Ecological Footprint divided by the total population of the nation. To live within the means of our planet's resources, the world's Ecological Footprint would have to equal the available biocapacity per person on our planet, which is currently 1.7 global hectares. So if a nation's Ecological Footprint per person is 6.8 global hectares, its citizens are demanding four times the resources and wastes that our planet can regenerate and absorb in the atmosphere. Here are the ecological footprint national rankings from Global Footprint Network for the five worst nations: 1. China China has an ecological footprint of 3.71 hectares per capita and a biocapacity of 0.92 per capita. China’s total ecological deficit is -3,435.62, the largest in the world. As China’s economy continues to rapidly expand, people’s incomes are rising, and, as a result, so is their consumption. With the largest population of any country in the world at about 1.4 billion combined with inefficient resource use, China is depleting its resources quickly. 2. United States The U.S. has an ecological deficit of -1,416.05. Its ecological footprint per capita is 8.04 hectares and its biocapacity per capita is 3.45 hectares. The average US ecological footprint is about 50% larger than the average person in most European countries. The U.S. has more suburban sprawl, less public transportation, and uses more energy and water per person than other comparable, developed countries. Additionally, California has the same ecological footprint as France. 3. India India’s ecological footprint per capita is 1.19 and its biocapacity per capita is 0.43 hectares. India’s total ecological deficit is -878.05 hectares. India represents about 6% of the world’s ecological footprint. India, like China, has a population of over 1 billion people. While India’s ecological footprint is relatively low, its biocapacity is much lower, leading to its large deficit. 4. Japan Japan’s ecological footprint is 4.65 hectares per capita and its biocapacity is 0.59 hectares per capita. Japan’s ecological deficit is -547.18 hectares, the fourth-highest in the world. A majority of Japan’s ecological footprint is made up of Japan’s carbon footprint. If everyone lived based on the Japanese standard of living, we would require the equivalent of 2.3 Earths to support the world population. 5. United Kingdom The U.K. has the fifth-largest ecological deficit in the world of -483.83. The U.K.’s ecological footprint per capita is 4.20 hectares and its biocapacity per capita is 1.08 hectares. Between 2014 and 2016, the United Kingdom’s carbon footprint dropped 11.7% driving the country’s total ecological footprint down by 8.8%. Although the U.K.’s ecological deficit is the fifth-highest in the world, the country seems to be moving in the right direction. A note on hydropower: In addition to methane, hydropower can have significant environmental effects such as fish injury and impact on downstream water quality. By diverting water out of the water bodies for power, dams remove water needed for healthy in-stream ecosystems thereby disrupting the natural river flows. Dams also slow down the flow of the river. The size of the reservoir created by a hydroelectric project can vary widely, depending largely on the size of the hydroelectric generators and the topography of the land. Hydroelectric plants in flat areas tend to require much more land than those in hilly areas or canyons where deeper reservoirs can hold more volume of water in a smaller space. At one extreme, the large Balbina hydroelectric plant, which was built in a flat area of Brazil, flooded 2,360 square kilometers-an area the size of Delaware-and it only provides 250 MW of power generating capacity (equal to more than 2,000 acres per MW). In contrast, a small 10 MW run-of-the-river plant in a hilly location can use as little 2.5 acres (equal to a quarter of an acre per MW). PS: Love Canada and Canadians, so don't get the wrong idea. But we also need to be realistic about the problems and their causes. Had always admired Canada as being very environmentally conscious, but with the Alberta tar sands, Canada placed greed before the health of humans and the environment. Canada is by no means alone in this area; plenty of other nations are guilty of the same. My own country, the U.S., is likewise a large source of the problem, and we need to do much more to change our own policies and lifestyles. Greed may improve quality of life in the short-term, but it is inexorably killing us and destroying quality of life for all of us in the long term.

BEV can get charged easily at home or at any charging stations which you can find easily. A level-2 BEV charger costs only US$600. Hydrogen fuel cell vehicles on the other hand are different stories. You can't charge at home, unless your house has the space and all the safety certifications and insurance policies to cover the hydrogen fueling tank. BEV with one full charge can travel 300km.

@@Strawberryknight maybe instead a plug in hybrid battery/hydrogen car could be used. about 100 km of battery range for work traffic, which you can charge at home or at work, + 400 more from hydrogen for long distance rides. Both technologies use electric motors so they are compatible. The benefit of hydrogen over using superchargers is that hydrogen is much more friendly for the grid, as the gas station could simply produce hydrogen at a steady rate during the day and store it. Superchargers work, but they generate very large peak loads, thus also requiring expensive infrastructure. If such a car were to be designed in a smart way it might even be possible to use the fuel cell as an electrolizer and fill it up slowly from something like a level 2 charger at home. There is also the point of storage, something we will need quite a lot of to overcome the seasons unless we go full nuclear. And since batteries are not a viable means of long term energy storage, you will have hydrogen produced anyway for during the winter.

@@coen270 *about 100 km of battery range for work traffic, which you can charge at home or at work, + 400 more from hydrogen for long distance rides.* Problem with that is that hydrogen actually doesn't offer that much extra range with passenger cars. *The benefit of hydrogen over using superchargers is that hydrogen is much more friendly for the grid* The thing is that the grid can manage if it is updated/reinforced, it just requires funds. However this wouldn't be any different for these fueling stations and everything around it. *as the gas station could simply produce hydrogen at a steady rate during the day and store it* Except hydrogen needs around 3 times the electricity, so you'd still put some extra strain on it. And then you also need add the infrastructure to produce the hydrogen which won't be cheap either. And lastly most people can just charge their car whenever it is best for the grid, all they need to be able to do is plug in their car as much as possible. Fast charging really only should be done on longer trips or when you have no other options, so overall the fastcharging shouldn't put that much extra strain on the grid compared to your proposal. *it might even be possible to use the fuel cell as an electrolizer* A fuel cell doesn't have that capability and even if it could, the pressure in the hydrogen tank of your car is very high, so you'd also need a strong compressor in your car. If it was that easy to produce hydrogen at home and refuel your car, hydrogen cars might be more popular currently. *There is also the point of storage, something we will need quite a lot of to overcome the seasons unless we go full nuclear. And since batteries are not a viable means of long term energy storage, you will have hydrogen produced anyway for during the winter.* No, you really don't want to use hydrogen for that application, you'd need a shitload of storage space, making it very expensive.

This shows me that the hydrogen interests are elbowing aside the direct uses of surplus green electric production to divert that resource to their preferred system of storage. That they can maybe remove some of the extra steps used in that hydrogen production is a long way off, so the existing methods will prevail for the time being. The cheaper brown hydrogen from natural gas pipelines already amortized means if the research money runs out society will be stuck with natural gas burning for steel production and natural gas conversion to brown hydrogen for those submarine's fuel. The priorityfor the economy should be renewable electric energy production and storage for battery storage, even distributed storage in the growing fleet of EVs connected to the grid for long periods of each night. IF there remains surplus electric generation then produce green hydrogen. This would most likely be done in the south of Europe and piped in to where it can be used for steel production or some forms of longer range air travel. Those submarines are a niche use and minor to the size of the environmental problem we seek to solve. As to the fuel cell cars, they will die a natural death in that marketplace. They already are being surpassed by long range battery powered vehicles on sale today. Your petrol vehicle collector driving the Hyundai has but one excuse that makes any sense at all, that 5 minute fueling.

Simple, lobby to govt that all new house builds require to have solar, electrolyser, battery, fuel cell as standard with hydrogen stored using metal hydride tanks. Each house can then feed their own home with green energy and when batterries are full will then create hydrogen as a long term storage. This storage can be used as a battery backup or fill the car up. Lower the energy grid and become self sustainable.

[@Strawberryknight]

And a level-2 EV charger only costs few hundred bucks without any change to install anything. Hydrogen is a mess and you need safety certifications for the building and huge insurance policies to cover just the hydrogen tank. Also, fuel cell battery costs 10 times more than lithium-ion battery. When you can use electricity to charge directly lithium ion battery, why would you use the electricity to power the electrolyser to generate hydrogen and then charging the fuel cell battery?

The vast majority of people drive < 50 mi (80 km) daily. Lugging around more battery capacity is extremely inefficient when considering the cost and resources to build that extra capacity plus the extra weight. Hydrogen tanks + electrolyzers make more sense in these regards. Analogous to today's PHEVs, Hydrogen tanks + an electrolyzer in combination with a 50 mi battery may be the perfect future compromise for folks with home garaging who can recharge overnight. For the rare trips exceeding the battery limit, they could then use hydrogen. Also, in the U.S. only 50% of personal vehicles are garaged which means only they have access to home charging. Currently, BEVs only make sense for folks with garages and not coincidentally the enthusiasts are in this more affluent demographic. The time required to charge at a public fast charger continues to BEVs prohibitively inconvenient otherwise.

[@sixtus9559]

Battery technology is moving forward forward so charging times won't be a huge problem in the future. The range is even nowadays on a similar level in comparison to a combustion car. Hydrogen needs to be used in steel and chemical industries because they need something in their chemical reactions that takes the place of coal. Coal "pulls,, out the oxygen, the reaction looks like this:" FeO2 + C= Fe+Co2. So instead of using carbon hydrogen is used, you get the same reaction but switch out the C with an H.

Canada: In Alberta, we have the largest production of tar sands, one of the dirtiest fuels, polluting our rivers, soil, and air! Canada's ecological footprint pre capita was graded at 8.17, just below the U.S. at 8.22 (2016), which is higher than European nations. Some small oil-producing nations like Kuwait and UAE produce far more greenhouse gases because of their refineries. But the problem is about more than just who is producing the most greenhouse gases or who is producing the most green energy; it also involves who is consuming the most products made with those greenhouse gases, who is most exploiting Earth's resources faster than they can be renewed? Now, the figures given were for per capita, but if we look at national rankings without regard to population and other factors such as China and the U.S. being major exporters, then those rankings change. But one could well argue that per capita ratings are a more accurate and fair measure. In that regard, Canada is on par with the U.S., Oman, Mongolia, and Australia, the only five in the world which require more than 6.7 global hectares per capita. ECOLOGICAL FOOTPRINT PER PERSON: The Ecological Footprint per person is a nation's total Ecological Footprint divided by the total population of the nation. To live within the means of our planet's resources, the world's Ecological Footprint would have to equal the available biocapacity per person on our planet, which is currently 1.7 global hectares. So if a nation's Ecological Footprint per person is 6.8 global hectares, its citizens are demanding four times the resources and wastes that our planet can regenerate and absorb in the atmosphere. Here are the ecological footprint national rankings from Global Footprint Network for the five worst nations: 1. China China has an ecological footprint of 3.71 hectares per capita and a biocapacity of 0.92 per capita. China’s total ecological deficit is -3,435.62, the largest in the world. As China’s economy continues to rapidly expand, people’s incomes are rising, and, as a result, so is their consumption. With the largest population of any country in the world at about 1.4 billion combined with inefficient resource use, China is depleting its resources quickly. 2. United States The U.S. has an ecological deficit of -1,416.05. Its ecological footprint per capita is 8.04 hectares and its biocapacity per capita is 3.45 hectares. The average US ecological footprint is about 50% larger than the average person in most European countries. The U.S. has more suburban sprawl, less public transportation, and uses more energy and water per person than other comparable, developed countries. Additionally, California has the same ecological footprint as France. 3. India India’s ecological footprint per capita is 1.19 and its biocapacity per capita is 0.43 hectares. India’s total ecological deficit is -878.05 hectares. India represents about 6% of the world’s ecological footprint. India, like China, has a population of over 1 billion people. While India’s ecological footprint is relatively low, its biocapacity is much lower, leading to its large deficit. 4. Japan Japan’s ecological footprint is 4.65 hectares per capita and its biocapacity is 0.59 hectares per capita. Japan’s ecological deficit is -547.18 hectares, the fourth-highest in the world. A majority of Japan’s ecological footprint is made up of Japan’s carbon footprint. If everyone lived based on the Japanese standard of living, we would require the equivalent of 2.3 Earths to support the world population. 5. United Kingdom The U.K. has the fifth-largest ecological deficit in the world of -483.83. The U.K.’s ecological footprint per capita is 4.20 hectares and its biocapacity per capita is 1.08 hectares. Between 2014 and 2016, the United Kingdom’s carbon footprint dropped 11.7% driving the country’s total ecological footprint down by 8.8%. Although the U.K.’s ecological deficit is the fifth-highest in the world, the country seems to be moving in the right direction. A note on hydropower: In addition to methane, hydropower can have significant environmental effects such as fish injury and impact on downstream water quality. By diverting water out of the water bodies for power, dams remove water needed for healthy in-stream ecosystems thereby disrupting the natural river flows. Dams also slow down the flow of the river. The size of the reservoir created by a hydroelectric project can vary widely, depending largely on the size of the hydroelectric generators and the topography of the land. Hydroelectric plants in flat areas tend to require much more land than those in hilly areas or canyons where deeper reservoirs can hold more volume of water in a smaller space. At one extreme, the large Balbina hydroelectric plant, which was built in a flat area of Brazil, flooded 2,360 square kilometers-an area the size of Delaware-and it only provides 250 MW of power generating capacity (equal to more than 2,000 acres per MW). In contrast, a small 10 MW run-of-the-river plant in a hilly location can use as little 2.5 acres (equal to a quarter of an acre per MW). PS: Love Canada and Canadians, so don't get the wrong idea. But we also need to be realistic about the problems and their causes. Had always admired Canada as being very environmentally conscious, but with the Alberta tar sands, Canada placed greed before the health of humans and the environment. Canada is by no means alone in this area; plenty of other nations are guilty of the same. My own country, the U.S., is likewise a large source of the problem, and we need to do much more to change our own policies and lifestyles. Greed may improve quality of life in the short-term, but it is inexorably killing us and destroying quality of life for all of us in the long term.
