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 (http://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.

im sure you'll build it yourself. I made it 2 weeks ago thanks to Avasva website.

A new alternative energy is born .
More efficient than current alternative energies !!!

My system does work so u don't use the water up rescurlate the same water

Please quickly make EV car for using in the world and stop using oil any more so that the world will be green soon, ,,,

Why are you not developing hydrogen energy where there is an abundant supply of it on earth. are you also part of the petroleum cartel?
Ray Shepherd
I find it interesting that one of the first picture shows wind turbines just off the shoreline. I don't think that would fly for folks that like their views.

Bro have u made a project or a model on this topic??

The notion that renewable energy is not enough to power a modern society is belied by the Danes doing exactly that. We don't need nuclear power, just smart resource management.

Very nice vedio. By which software you make this vedio

The approaches presented here are doable, make sense, and are good for everyone. So much so that I'm confident that as much as 5% of the U.S. Congress will support it!

Renewable is a joke, only idiots or ignorants think that renewable is better than nuclear.

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.

Using battery storage is now something that they will likely include. The technology wasn't available when this video was made.

i thought Solar Freekin Roadways were the future!?

...Or just buy Russian clean natural gas at 1/5 the prices.

Burning Biomass gets a lot of criticism from green purists, does Denmark know something we don’t?
Mark Heslep
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.

17 minutes of aspirational assertions - not one mention of costs.

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

How much land mass would renewables need to power a nation like the UK? An entire country's worth. In this pragmatic talk, David MacKay tours the basic mathematics that show worrying limitations on our sustainable energy options and explains why we should pursue them anyway. (Filmed at TEDxWarwick.)

Lesson by David MacKay.
