Mankind is facing the greatest upheaval since industrialization. To stop climate change, the energy system must be transformed worldwide and fossil fuels must be completely replaced. But is this even possible?

Time is running out. If climate targets are still to be met and the survival of future generations is to be ensured, virtually all fossil energy sources worldwide will have to be replaced by renewables by 2050. That leaves us with almost exactly one generation from today to make this massive change. So what needs to happen for the global energy transition to succeed?

Part 1 of this two-part documentary looks at the question of whether it’s even possible to provide enough green energy for the whole world. How can the oil economy be replaced? The film travels to places that could one day become the Saudi Arabia of renewable energies. For example, gigantic offshore wind farms in the North Sea, or the most modern solar fields in Spain. One day, these regions will supply all of Europe with electricity.

However, the globally increasing demand for energy must be met in ways that are both sustainable and affordable. Researchers at the Technical University of Ilmenau in Thuringia are working with a team from the California Institute of Technology on high-tech materials that will make renewable energies more efficient and less expensive than their fossil fuel predecessors.

Part 2:    • Global renewables: Pioneering the ene...

    DW is the premier documentary station of the 21st century!!!! Living in the US but can’t stand the tv programs all full of cars, drugs, attorneys, insurance advertisements every minutes!!!! DW programs are so detailed and you can sit and watch with your kids knowing it will be the right content. It amazes me how rapid they produced richer documentary content. BRAVO!!!!

    1) shallow Geothermal (aka. heat pumps) for heating/cooling which reduces electricity demand by ~70%
    2) increase wind/solar/geothermal/hydro installation
    3) create walkable/bikeable cities (ebikes are most energy efficient method of transportation, including walking)
    4) install enough mass-transit (trains, busses), to eliminate the need for the personal automobile
  • @TrueBluePlus
    Love DW Channels about all Renewables, such a amazing place to learn new things!!!
  • @sandponics
    Here in Australia, 22 solar panels on the roof of my house provide me with five times more electrical energy than I can possibly use.

    I also wanna piintnout that thd fiber glass blades could be ground up and put into blocks to build house or tarmac forbroad surfaces

    You Can't Judge A Video By Its Cover. you can by its first few chapters and certainly by its last.

    This is like the Swiss talking about the problems of chocolate making without a single word on cocoa production.
  • @tushyranx5860
    That's Deutsch Welle for you; always exploring all angles
  • @user-nt4wv7me4g
    Why they are buying Big gas, diesel generator to supply, for example EV stations...
  • @TheRustyLM
    Nope. All that electricity requires metals & minerals that take millions of tons of fossil fuels to extract, process, smelt, transport.
  • @yellowluma101
    How do they come out with hour long professional, well edited and researched documentaries everyday???? I think I’m missing something
  • @chrislambaa7586
    A small comment about the recycling of the windmill blades. The company Vestas came out with news in february that they can now recycle the blades back to virgin materials, through a chemical process, and is working on scaling it up.

    I can't love DW more, so nice, inspiring documentaries. Amazing to keep us update on the new tecnologies. It is my second best television broadcaster just right after BBC.
