Our hunger for energy goes beyond all limits and will double in the next 20 years. But what available technologies could meet the growing thirst for electricity? And will we also have to cut power consumption? What can Europe learn from China? And could "decentralization" into so-called "microgrids" the future of energy?

What is supposed to be the largest and most efficient solar power plant in the world is currently being built near the Moroccan desert city of Ouarzazate. The Noor solar power plant, which means "Light" in Arabic, is due to be completed by 2020, when it will comprise 4 units. In its final expansion stage, Noor will supply a total of 1.3 million households with electricity. The sun is the most powerful source of energy in our galaxy and could theoretically supply all of humanity with electricity with ease, but what technologies do we have to usher in this new era of electricity?

Could wind power be a more promising alternative? Wind farms are being built at full speed around the world, but is wind energy really viable? Is the enormous investment in wind turbines at all worth it and can it meet our demand for electricity?

China has shown how quickly you can push ahead with the switch from fossil to renewable energy sources. China's enormous economic growth in recent decades has made the Middle Kingdom the world's largest energy guzzler. But China is also the world’s largest energy producer. A veritable energy revolution is currently underway. Almost 20 percent of the ever-growing demand for energy is now met by renewable technologies, and a large proportion of the solar cells used worldwide already come from China. What can Europe learn from China? One key to avoiding an electricity crisis could be "decentralization,” so-called "microgrids." A quiet little town in the Swabian Allgäu region has shown it is possible to produce eight times as much electricity as it needs itself.

lol,the chinese guy said that their standard of design was levels higher than foreign countries,and suddenly there is no translation.

if you want to know how to make it yourself , just go to Avasva webpage. There you'll find your answers :)

Use the Energy stored in batteries, that energy can be used to turn the turbines when there is no wind. bascially you are using the energy stored in batteries to spin the wind turbines when there is no wind and that energy goes back to the battery to be stored again. Creating a seamless loop .

Wie üblich, bleibt die Fleischindustrie bei der Klimageschichte unerwähnt.

oil gas and coal provide for the wilfully mindless consumers of that energy supply
but the energy market is anything but free from interference, and anything but open

Damn, the CCP scored some good free propaganda off of this one. Just because their officials claim one thing, doesn't mean it is true. You show the "solar highway", the solar lane clearly is closed for traffic, contrary to the interviewee's statements, the idea, albeit a bad one, is not a chinese original, contrary to the interviewee`s statements, large portions are visibly broken and overall official statements by a government known for it's nutorious lying are largely not questioned at all.

Buy my electricity, because I need a job and want to do something for you, which you should (can) be able to do or yourself. None of this is about energy production, it's about economies vying for dominance in a failing globalist empire. Wind turbines for home use are inexpensive, as are solar panels and we can heat our homes from Earth's stored power underground. The secondary battery market from partially reduced-capacity EV batteries can be paired with home generation methods.

Magnetism is the answer to all the problems concerning energy.
Who ever invents the shite will be the richest man or a dead man,whatever comes first!!

I have doubts about the renewable energy model described here. All the big decisions are in the hands of a few engineers, business tycoons and banks. They like the system as it is. They do not want to face the prospect of big lifestyle changes. They want life to go on as usual, only without fossil fuel. Is that realistic? Are the so called expert the solution or part of the problem? Very few if any of the experts interviewed here have a sound grounding in sustainability. Where is the public debate?

8:19 right, business doesn't make the country rich, it makes rich its investors. The country could get some taxes
Микола Моргун
5:41 there is something I didn't get. Where does the government get the money to subsidize the electricity? Why pay people to stay in the desert? What do those people do for life there?

The trouble with wind turbines at sea is that they have serious effects on sea life and migrations of creatures of the sea.
When on land then great amounts of area need to be cleared for both wind and solar power which of course again, effects land, forests and animals on land.
So in one yeah sure, it may help but at the same time also destroying the very things we are trying to save.
pia suoja
the solar and wind energy will NEVER work in places like Finland, this is junk csience, we cant live without coal and oil, we have to fight the overtake of our freedom to LIVE...+carbon dioxid is a PLANT FOOD, plants DIE when its under 150 parts per million, this is all junk science that leeds to totalitarian takeover by the shadow government of the world !!

Why can't the flow of cars driving over a pressure pad create energy? I seem to remember a school in the UK where every day the kids had to jump up and down at the entrance to create electricity as they went in.

Mobility is one of the world's biggest drivers of energy consumption.
The switch to renewable energies will affect people's everyday lives. How will we get from A to B when fossil fuel reserves run out in the future? How will we fly around the globe without oil and gas?

You can watch part 1 here: https://ufl.ae/videow/Z0Vy9Ptd07G

Mobility is one of the world's biggest drivers of energy consumption. The transportation of people and goods by road, rail and air accounts for around 34 percent of total energy consumption. The electrification of mobility has already begun and, as the example of Norway shows, it could be one solution - but not for trucks and industrial vehicles. Is fuel cell technology a viable alternative here? Japan firmly believes it is.

Could electrification also revolutionize air transport? Siemens and Airbus want to make aviation history here and are working on a regional aircraft with a hybrid electric drive - but it won’t work for long-haul flights. But scientists from ETH Zurich and the German Aerospace Center are working on a spectacular solution to the long-haul problem: synthetic kerosene from sunlight.

An alternative to heavy oil is also being sought for shipping. Neither electric propulsion nor fuel cells will work for gigantic cruise liners and above all for the container ships that account for a large part of world trade. Methanol, which can be produced sustainably, could be the answer and a large prototype vessel is currently undergoing trials.

In addition to mobility, digitalization is one of the great power guzzlers of the 21st Century. Streaming services, cloud computing and the Internet of Things are all increasing our energy requirements. Experts anticipate consumption will increase by around 40% over the next 12 years. Microsoft's server farms alone will consume as much electricity as a medium-sized European country. Where's that power going to come from? We have to cut back our consumption.

This will also apply to our future lives. The world's first self-sufficient apartment building is located in Switzerland and shows how you can become energy independent. The future will be in networked houses that exchange electricity among themselves.
