Smart Energy Systems: 100% Renewable Energy at a National Level (Full Version)
Denmark has decided to become independent from fossil fuels. For the sake of the climate, the economy, and in order to ensure security of energy supply. This film shows how this will happen based on research conducted at Aalborg University (www.smartenergysystems.eu).
At present wind and solar energy already delivers a good share of Denmark's energy, but renewable energy is a major challenge for an energy system that is built upon fossil fuels. Energy production from wind and solar fluctuates - it fluctuates as the wind blows. So what renewables are reliable when there is no sun or wind energy available?
Another challenge is the transport sector. How do we create an energy system of renewable energy, where also cars, ships and planes can operate on fossil-free energy? A great example of an energy system that will ensure Denmark a 100% renewable energy system is called: Smart Energy Systems - a coherent, fossil-free energy system that will create lots of new jobs and green energy for the Danes, both in terms of electricity, heat and transport.

I can see how biomass is a benefit to the farming community BUT it is still a thermally inefficient means of energy production because it requires COMBUSTION to produce the thermal rise that boils the water which creates the steam which spin the turbines in the house that Jack built. You would be better off putting the crop energy into organic food production and capturing the plant waste or slag CO2 to recycle into a heat plant. OXIDATION of a fuel source is not a 21st Century method of production, and nuclear FISSION has huge radioactive footprint and a storage problem that will be with you for CENTURIES. The only possible nuclear solution is THORIUM FUSION but that is decades away from practical. My advice in colder northern climates is to SKIP BIOMASS COMPLETELY, concentrate on 100% wind/solar/tidal and geothermal, and look at biogasses when you need to burn off methane from rotting organics/compost.

The stacked graphic showing the variability of wind, solar, and wave is misleading, and not slightly so. It shows solar output expanding and contracting, when in fact it goes all the way to zero everyday at the onset of peak evening load. In winter, solar output can become insignificant for six weeks. So too wind and wave in the off season.

New engine at 60-75% that can run 5 fossil fuels and NH3 is needed and eliminates the need for electric cars/truck etc. Old Otto/Diesel engines cannot be converted well to NH3. Excess wind and solar makes NH3 that then is stored and used in vehicles, airplane, boats, ATVs, camper, trucks, track hoes and anything that needs power. This system you propose can be taken down easily with a shortage from one or the other sources. NH3 should be the common fuel for everything, including farmer's trucks and fertilizers, plastics and more. NH3 is one key not discussed in this video and the other is a new engine like suggested. Happy to discuss how to get Denmark off of oil ASAP. It is very doable. With this new engine Denmark could compete with German car companies....lots of jobs. see tweets @seaplaneguy

Complicated solutions , re digesting inefficient systems like solar and ugly wind systems is obviously not the way to the future. hanging to a "straw" should not be the way to the future also . forcing people to limit their freedom to use public transport is not the future. the solution will be simpler , more independence and freedom to all with innovative and simpler , much simpler solutions will take us from the past to the future.

How nice for once to hear intelligent people carefully getting the complete picture and actually having the numbers check out as opposed to Danish politicians that either think getting EVs without any other energy infrastructure investments will solve global warming or small changes to lifestyle will makes us fulfil the Paris agreement. If Danish politicians were smart they would pass a law stating that no politician is allowed to make decisions about energy without consulting engineers or at least someone that understands thermodynamics.

I think that most of this looks like a fine plan to me but hydrogen production through electrolysis of water is not a good idea. It is far too inefficient at storing energy. The conversion losses are massive. Batteries and compressed air are much better options. Also where is the hydro power in this? Hydro dams are excellent grid scale batteries

Once society learns to live in the renewable energy world this becomes simple. Stop being so spoiled and greedy. Learn to live with fluctuating energy, stop demanding energy any time you want. Live differently, consider working during dark hours, the energy for lighting would be more than offset by air conditioning costs.

Yet, the Danish average CO2 footprint per person is 14 tonnes yearly, higher than Germany and not far behind the Americans. CO2 doesn't care how it is made and Danes Fly a lot and buy a lot of consumer goods. Also commuting by car is rewarded by tax deduction (60 cents/mile). So having the Greenest energy production infrastructure, does not give Denmark a free pass to gloat.

Denmark is currently in the enviable position of being able to rely on Norway's large reserves of hydro electric power. So when the winds not blowing, Norway fills the gap. If the wind generated electricity is in abundance, Norway takes the excess to refill their pump storage dams. Denmark pays a lot for Norways power and gets much less when it sells back to Norway. Hence the high cost of electricty in Denmark. It is not a model for other countries to copy.

It is technically impossible to get 100% of our electricity (never mind energy) from conventional renwables. (I exclude biomass, as it is used, as it emitts CO2 and destroys forests due to the volume required) As is known the sun doesn't shine all the time and solar output is variable due to the angle of incidence of the sun and the clarity of the atmoshere. Cloud, rain and snow seriously degrade solar output. There are times that the wind is very weak and as the output varies as a square law (A rough estimation, worse at lower speed and less at higher ones) power drops off quickly as wind speed drops. The other associated problem with wind speed and direction is in blustery conditions the output is unstable and adversely affects all devices connected to the grid. The amount of storage to balance all the above very real problems is unsustainable. The thought that storage is the answer but neglects to factor in the extra power needed to re fill the storage devices from a very variable source. Simply put trusting the weather to perform. Would you want to bet on that? You cannot beat the physics of the system and as all sources of energy have known energy density, it's obvious that renewables are a poor choice as they all have very low energy density.

No such thing as renewable energy it takes 240.000 tons of C02 to build a 3 million dollar wind mill because of all the coal you have to burn to make the 32,000 tons of cement 12,000 tons of re-bar for an 80 meter wind turbine plus all the coal needed to make the steel transmission and bearings plus the oil needed to make the carbon propeller. Then all the lubricant for the $250,000 transmission and bearings which may last 10 or 15 year at most. The new cement wind mill may last 35 or more years over water a lot less. At the end of 35 year the decommissioning of the bird killer may take as much C02 as the construction. One massive farm is now being decommissioned in Alberta the cost and the dangers are very high.

if electric cars will use a 3rd of a countries electricity, can't you just increase the price of electricity for cars when there's no wind on Monday and store excess electricity until it stays blowing again on Thursday and then lower the price again? people should be able to get by on their own local solar power or buy increased price stored power If they're going somewhere while renewables and stored power generate 110% to 200% of the remaining energy... needs....

Burning natural gas less bad because a higher portion of its energy content is from Hydrogen so less CO2/kWh. But on its own it is nowhere green enough to make a difference. The only truly carbon free liquid fuel is Ammonia that is only Nitrogen and Hydrogen. This can be made by renewable sources and transported as a liquid at low pressure, used in car directly decomposed through a catalyst as Hydrogen.

The more we utilize energy fully we will find less reasons to work and this will decrease demand. The whole economy is driven by energy but is the major reason why we work so by creating energy independence we will refine the reasons why we work and eliminate unnecessary processes that are nothing more then a drain on resources and that are a negative benefit to society. It will be much like the dissolving of the monopoly of AT&T. What will happen in a short time will be a complete shift in why people work. Cause 80 percent of every dollar is just to support the use of energy and is the driving force behind money so will utilizing energy better we will reduce the need to work and the justification of comforts to oil and energy companies who want to continue to be their slave to ignorance. Over half the world represents the interests and well being of a digital number so these people are really working against us instead of for us because every decision made in moneys interests goes against human and natures interests. Which is more important?

Yep, but it will not be as long as we live...Right, we will even be gone before that. You use energy, clean energy or other, it's gone for ever. But, my advice, use sun and windenergy as long it is there !!!

Ok so how do you make the renewable energy solar panels, or the wind generation plants oh that's right with fossil fuels. How do you replace a wind turbine motor out in the sea, oh yes with a fecking helicopter powered by fossil fuels. Yes it's great to save money in the short term on energy but to make one solar panel means that; that one panel needs to run for 25 years without breaking down before it even becomes carbon neutral before it even starts to pay back to the climate.. green energy is a joke and is not the solution to our problems...
George LFC

MrKohlenstoff I don't but I deal with sustainability all day, and all you have to do is the numbers. Eg take wind generation it takes a huge amount of iron ore to dig out of the ground all with heavy machinery run on fossil fuels, then there is transport, making it, more transport, plus people power because hey 90% of western people eat meat and dairy which is huge on its own. Anyway if it takes at least 10 years for the fossil fuels we burn today to have its effect on the planet and then you factor in breakdown costs, maintenance costs (again people) and each time you replace a component or even do maintenance on it another 10 years kicks in for that task. Even being conservative it is at least 10 years, if we went on a building spree of green energy today the amount of fossil fuels we would burn to make it, in 10 years would put us past the target rate regardless of how green it runs today the damage in manufacturing is were the issue is. We should have done it 30 years ago..

Are they vegan or meat eaters? Do they drive to work ?etc. what materials are they made from? What's the process to manufacture? How many people does it take to make one? How is it transported to site? How is it erected? What's the replacement of parts, what if a motor burns out how does it get replaced? What's the impact of birds or other flying animals? How is the power transported and stored to the home? We are only taught to look at the end product and never consider what's involved to actually make it..green power is a product to keep industry going and it can only be derived from fossil fuels.. fossil fuels is not just oil, gas, and coal, concrete and animal ag is also considered a fossil fuel because of its environmental impacts which are much much bigger then oil, gas, and coal... can wind and solar generate enough power to melt steel?

The now standart nucleair reactors cost way to much to build, already build ones for the time being are cost effective to keep open mostly but nobody will invest in new plants. Thorium will all depend on price, they are claimed to be cheaper but such projects never stay in budget it always seems. It will come down to price, nobody is going to build huge expencive plants if renewables are cheaper (I mean including storage) Maybe Japan/france build some thorium plants before renewable prices drop below the point that nobody wants to compete anymore. I can't predict the future its possible price drops lvl out on renewables and the thorium plant is as cheap as they claim, in that case we will see more of them =P But I don't expect that to happen

I guess you mean "... won all of them..." Current nuclear power plants are quite good in submarines and aircraft carriers (with limitless water) as they were designed on Navy requirements, which do not translate so well into civil inland applications. In the short term nuclear seems necessary (specially if you consider the CO2 emissions of coal or gas) but unless fusion is achieved or we move to salt molter reactors I still think (and can support with facts) that nuclear must only be used for very specific situations and not for mass energy production. And again in the economic part, try to also include the crazy amount of time that some radioactive waste need to be secured (only that part make nuclear the most expensive energy of all)

+I A Reid It's not as simple as you put it. Denmark sells wind energy to Norway during nighttime in order for them to pump the water back up in the dams, during daytime they then generate power. Denmark also get about 40% of their energy from wind alone, now put on top of that hydroelectric energy from Norway and it makes up for more than 1/3rd. Both solar and wind has become much cheaper in the past years, and if done right, the energy can actually be cheaper than conventional forms. But it all depends on where the country is located.

Denmark is not able to rely on their renewable generation, only about 1/3 rd of their power is renewable. What they do rely on is their neighbour Norway which has large hydro generation capacity, That is just fortunate for Denmark that their geography is suitable for hydro which is a very good source of power, Many countries do not have that resource. Wind and solar are pretty poor sorces of power, and time has proven this to be so. Neither are the future.

The electric car for example uses so much fossil fuels to manufacture that it is still releasing carbon into the atmosphere 20 years later even if it's parked in a garage and never used. In fact a vegan who drives a normal car to work releases the same amount of carbon that a meat eater uses when riding a bike... if you are serious about reducing your impact go vegan if you can't do this then don't worry about anything else you are just throwing money away. Don't get me wrong I save money with having solar while the payback for my pocket is 5 years, the payback to the climate is 25 years and what's the point of spending money to save money if it doesn't matter I'll still kill the planet...

Mauro, all expensive pie in the sky ideas, If and maybe just is not good enough, renwable generation is but a small fraction of our requiremenmt and the times that their output exceeds demand is insufficient for all the batteries you can muster to make up the shortfall. And it's at a large cost.

What happens when tourists come to visit Denmark in 2050 and cannot refuel their unconverted car because the country is 'independent' of fossil fuels? Surely they will still need to buy fossil fuels on some scale until the rest of the world can catch up.

After watching probably hundreds of videos on renewable energy, I am convinced there is no magic bullet. I think eventually (not in my lifetime) that a combination of different methods will be used for a completely sustainable energy future. This will involve geothermal, hydro, various types of solar technologies, wind, hydrogen and bio liquid fuels made from algae. Algae is carbon neutral because it removes the same amount of CO2 that it releases during burning through the process of photosynthesis during the time it is growing. But all this will not happen until the cost of oil and other fossil fuels reaches a point that is higher than the cost of producing green energy. But there again, I might be completely wrong on my assumptions.

If you are looking for a magic bullet to really make a difference in the global energy problem, look into generation four reactors (search molten salt reactors). However the only reasonable solution to our global energy shortage will be to use every and all types energy generation, storage and efficiency techniques.

The Russians were experimenting orbital mirrors in the early 90s to reflect sunlight onto solar power plants, increasing their energy production and eliminating their downtime during night. Unfortunately due to lack of funding and the fall of the USSR the experiment was halted then cancelled. It'd be cool if we have orbital mirrors generating electricity or warming up northern cities.

Just like in Spain that the State is shamelessly protecting the cartel of 5 big energy corporations by way of charging a special tax on the sun... That is to say, any residential individual interested in installing solar panels, which will be hooked to the national grid is being taxed to an extent such that the investment will not be payed off until well at the end of the equipment's useful life, thus becoming unfeasable. This in the country where the "sun shines" the most in Europe... And then people are surprised that Catalonia wants to become independent from incompetent, corrupt, evangelical and pre-modern ugly Spain.

+Paul McGreevy 1) Generate solar power and store it at your place instead of delivering it to the national grid. 2) You will be still connected to the grid in order to consume the electricity provided by the electricity company. I agree with your statements regarding and related the solar energy being dependent on the number of sun-hours.

321ozzy The greater metropolitan area of Tokyo has 36 million people what cost would the batteries be to support a city like this. What if there was bad weather for a few days or a week? On the second day the batteries would be drained and the city would grind to a halt. Solar power is intermittent and variable. You still have to have a conventional grid which would be running very inefficiently or you would have to have sufficient storage capacity
321ozzy
321ozzy 3 months ago
+Paul McGreevy That is why the solar panel users should store the energy in batteries and not send it back into the grid. A small fee for the maintenance cost of the grid is understandable. On the other hand, a lot of tax money goes to the fossil fuel maffia, I mean companies, because they are losing income... Reducing energy use on behalf of the population is also to be looked into, many ways to reduce without even having to sacrifice comfort.

Same occurs in Hawaii and Nevada and other places. This is the problem. The companies that provide the grid and make everything work start to lose business when too many people get roof panels up to the point where they would have to go bankrupt. To stay in business they have to pay less for feed in power and make a bigger service charge to cover their cost. This is why solar can’t work. Solar farms don’t work either because you need 180 square miles of panels to match a 3Gw nuclear power station. The panels require extensive energy intensive mining to manufacture and they have to be repaired and replaced regularly. Imagine the land costs involved. Totally impractical. Wind requires 1,000 square miles for same energy production. The only thing renewable about these energy sources is the sun and the wind. Everything else needs manufacture and maintenance and repairs and regular replacement and lots of expensive land.

Sadly, many groups quote Dr James Hansen on the problem of climate change, while ignoring his stated *solution*. He says: 1. Believing in 100% RENEWABLES is like believing in the Easter Bunny or Tooth Fairy. (Yes, he's aware of all the 'studies' that say we can, but still thinks storage is ridiculously expensive and cannot do the job). goo.gl/8qidgV 2. The world should build 115 reactors a year* goo.gl/Xx61xU (*Note: on a reactors-to-GDP ratio the French *already* beat this build rate back in the 70's under the Mesmer plan. 115 reactors a year should be easy for the world economy. France did it *faster* with older technology, and today's nukes can be mass produced on an assembly line. Also, GenIV breeders are coming that can eat nuclear waste and covert a 100,000 year storage problem into 1000 years of clean energy for America and 500 years for the UK with today's levels of nuclear waste).

Roger Reimer 1 second ago No such thing as renewable energy it takes 240.000 tons of C02 to build a 3 million dollar wind mill because of all the coal you have to burn to make the 32,000 tons of cement 12,000 tons of re-bar for an 80 meter wind turbine plus all the coal needed to make the steel transmission and bearings plus the oil needed to make the carbon propeller. Then all the lubricant for the $250,000 transmission and bearings which may last 10 or 15 year at most. The new cement wind mill may last 35 or more years over water a lot less. At the end of 35 year the decommissioning of the bird killer may take as much C02 as the construction. One massive farm is now being decommissioned in Alberta the cost and the dangers are very high.

+Bradley Huffstetler No, it is considered quite a bit. The difference is that it is easier to clean up a handful of smoke stacks than it is to clean up millions of tailpipes. Many power plants are moving to Natural gas. You have the solar and wind options. Where I live in the Northwet we have loads of hydro. Power walls for homes are being considered to lower the need for peak load power needs. Coal, oil and natural gas plants are used most often for peak load conditions because they are faster to turn on. So if you add a buffer you can better manage your base load. Fuel delivery to a single power plant and propagation of that energy out to homes via wires is cheaper and more efficient than delivering the fuel to your local gas stations. If you didnt have to deliver to the local gas station you would also lower congestion on the roads. The amount of electricity to manufacture a gallon of gasoline in electricity could conceivably power an electric car for about 60 miles... One caveat though. Most of that energy is heat to crack the oil to make gasoline so that energy doesnt directly transfer there are energy losses to convert to electricity. Physics getting in the way again. I happen to be very close to someone who works for a electric company. There is a lot of work being done to reduce the need for peak load power generation. At least this power company seems to be concerned about its public perception and really tries to do the right thing. Like so many companies they dont always get it right but I would say they really try. Something else more important than efficiency in some ways to me at least. If you believe in the capitalist system you should have choices and be able to vote with your pocket book. I have a Prius and Leaf. This means I have Cut my Koch Brothers taxes by 2/3. I send 2/3 less money to the middle east dictatorships. In the Northwet I keep most of my energy money right here in the Northwet.
Bradley Huffstetler
So many good points in one reply.. I, like probably many people who read about this stuff, have never stopped to think about the energy to produce the gasoline/diesel itself. Completely negates the argument of "where do you think that electricity in your electric car comes from?"
LongTimeAtheist

Sadly Hydrogen gas is not an energy source. A popular miss conception. At best it is a poor storage medium. It takes a huge amount of energy to split water into Hydrogen and Oxygen. You can use natural gas as a Hydrogen source it still takes a lot of energy to extract the hydrogen. Then to store / effectively transport Hydrogen it takes more energy to compress it to somewhere around 10,000 PSI. Now you can burn Hydrogen in a Internal Combustion Engine which is at best 20% efficient. The other method is Fuel cell vehicle. The fuel Cell vehicle converts the compressed Hydrogen to electricity and stores that electricity in a battery which drives an electric motor. A good reference artical with more data. electrek.co/2016/04/26/automakers-fuel-cell-hydrogen-electric-vehicles/ So after all those conversions the physics of hydrogen just does not work out. Unless you can store the energy from the explosion of a hydrogen bomb. Also known as Nuclear fusion. We are working on that. Not there yet. It is far more efficient to store the electricity into a battery from your electric company then drive an electric motor. Strangely enough it takes about 6 KW to refine 1 gallon of gasoline. A Nisan leaf's battery pack can hold 24 KW and gets around 96 miles. Thats about 24 miles per 6KW or 24 miles that you could get by not refining that gallon of gas. Thats only the refining cost. Dont forget the energy that it took to pump it out of the ground, Ship it from there it was pumped and shipping it from the refinery to your gas station. Now there is the argument that coal is used to charge the electric car. They forget to tell you that coal is used to refine that gallon of gasoline. (That is a net / net) Gasoline has the additional pollution of Oil / coal is used to pump the oil out of the ground, shipping it around the world. Then finally the exhaust that comes out of the tail pipe. Electricity doesnt need to be shipped via vehicles. It is shipped via pollution free wires. I hope this helps to understand the really big picture of energy. Physics always tend to get in the way.

57 nuclear accidents since 1986, averaging out to just over two nuclear accidents each year. 4,000 fatalities in the Chernobyl disaster. 600,000 people still suffering from the effects of Chernobyl. 8,015 overall deaths from the Kytshym disaster. 35 deaths from the Windscale fire. 181 other deaths from accidents in nuclear plants around the world. Nuclear explosions can permanently damage DNA. In 2011, 15 years after the Chernobyl disaster, wolf carcasses were tested for radiation and revealed that the wolves had extremely high levels of radiation. So high that they shouldn’t have been touched with bare human hands. Birth defects in wolves around Chernobyl have nearly doubled since 1986. The waste from nuclear power plants will be toxic to humans for 100,000 years after it is released. There are at least eight relatively easy ways to cause a nuclear meltdown. This is an easy act of terrorism. Living near a nuclear plant can increase the risk of childhood leukemia and other forms of cancer even if there is no meltdown. There are not enough sites safe from earthquakes, tsunamis, and other natural disasters to operate safe nuclear power plants. Even if there were enough feasible sites for nuclear plants, our uranium would be depleted in less than ten years. www.debate.org/opinions/is-nuclear-power-bad-for-the-environment

Nuclear power suddenly doesn't seem so scary anymore... James Hansen really got me thinking. ruvid.net/video/video-JP-cRqCQRc8.html It looks like the year of Max CO2 needs to be 2020. Wind and solar alone aren't going to do that. Big Oil and Coal have managed to suppress nuclear by making people think it is unsafe, despite the fact that it saved 1.8 million lives that would otherwise have been lost to air pollution. Air pollution from fossil fuels is what causes heart disease, lung cancer, a lot of diabetes and Alzheimer's, not to mention asthma. Nuclear power frees us of most of that. We could have saved 140,000,000 people if we had rolled out Nuclear the way Eisenhour and JFK planned. But it is not too late. The Seeborg commission showed how. Nuclear plants from companies like ThorConPower or Terrestrial Energy can be cranked out by ship yards, many gigawatts per month. We can get ahead of climate collapse. Hansen knows and speaks about 3rd and 4th generation nuclear power. (Actually it is the MSR tech of 1953 we need!) But the downside Hansen shows is scary. He is claiming (and you have to listen carefully) that there is a good chance of 3 feet of sea level rise in 50 year. But that's not the bad news... 10 years later, it will be 10 feet. So our best team of climatologists are telling us that in 2076, the 300th anniversary of the USA, all our historic coastal cities will actually be history. Wiped out. But that's STILL not the bad news... Sandy wasn't a super-storm. But they're coming.
