Every year, the world uses 35 billion barrels of oil. This massive scale of fossil fuel dependence pollutes the earth, and it won’t last forever. On the other hand, we have abundant sun, water and wind, which are all renewable energy sources. So why don’t we exchange our fossil fuel dependence for an existence based only on renewables? Federico Rosei and Renzo Rosei describe the challenges.

  2. Cows produce methane…its renewable…transparent bouncy castle funnel pen…they spend half a day in the field…and night and the other half inside the pen…solves a lot of ozone emissions….methane can be combusted…a combustion engine can produce electricity…by turning a turbine…

  3. If allowing aviation to continue on with jet fuel much of the world could switch away from fossil fuels as an engineering challenge. Ocean ships could use small modular nuclear reactors that can be moved to deep water if not able to be shutdown effectively. By far nuclear power even at its high build costs along with pumped storage could provide electricity. People would need to accept living in 10 mile radius evacuation area of new nuclear power plants. Most road vehicles could be BEVs. In the US such moves would likely raise the cost of electricity substantially and there would be law suites against placing people's real estate and homes into evacuation areas of new nuclear plants. These costs would be lower than supporting large amounts of wild AC with the public power grid that uses expensive fuel intensive peaking power, more than making all the electricity from efficient running natural gas combined cycle plants that have three times fueling cost of a new USC coal power station.

  4. I can fix what is wrong with the renewable energy industry.
    Easily restore the grid back to what it used to be – when it ran on conventional fossil fuel.
    But without the detrimental environmental consequences.

    But half of the problem is whether you people even care, or want it to be fixed.

    I am quite seriously serious.

    You can look all you want, nobody haves a simple easy solution. Even my own fix will take time to implement if you choose to back my solution.
    But once it is up and running, it will provide dependable 24-7 reliable grid stability for the next 1000 years, unless something better becomes available.

    Your choice.
    Lobby your government representative today, — or not?

    Btw, my innovation is invulnerable to tornadoes rated EF5 or greater, as well as hurricanes, typhoons, blizzards, dust-storms, major catastrophic flooding and tsunamis – that would otherwise easily cripple or totally destroy any other established conventional renewable energy production technologies currently used around the world right now.
    With little to no environmental impact to nature and wildlife.

  5. It's interesting that those that claim 100% Renewables is feasible never include figures for countries like the uk and many in Europe or those at higher latitudes. We get days without wind and not every day is sunny. If you work out the battery size needed to keep the lights on its enormous. People need to use actual data and take into account reality.

  6. My innovation could be the holy grail of renewable energy, addressing the biggest challenges of sustainable power while directly benefiting the everyday person. By potentially providing continuous, on-demand electricity without reliance on fossil fuels, sunlight, or wind, it could drastically lower energy costs, freeing families from rising utility bills and unstable power grids. For homeowners, this means true energy independence, reducing reliance on external providers and offering a reliable, self-sustaining power source. For businesses, it could drive down operating costs and promote a cleaner future. In developing regions, it has the potential to bring affordable, uninterrupted electricity to communities that have never had it before, improving quality of life and economic opportunities. With the ability to make clean, limitless power a reality, this breakthrough could reshape industries, empower individuals, and lead to a world where reliable energy is no longer a privilege, but a universal right.

  8. but for now its still an easy fix instead of giving 100s of billions away for wars that are only being fought for land with oil, that will put more CO2 in the atmosphere making our planet worse off, we can spend that money on making solar, wind and hydro systems. we could easily power our entire country with that much money then start helping our neighbouring countries to do the same until the entire planet is using renewable energy 100%. With this set up every car on the planet could be electric and we would still have far too much to spare. Then we only use chemical gases fuels for rockets and planes until we further our technology to be at a point where we dont need them

  9. WE DO NOT HAVE ABUNDANT FRESH WATER. We have oceans that need desal that polute the ocean. We have solar panels that have to be mined from the earth. When they are old. They are discarded back into the earth. We have windmills, killing great birds and when they are old, they fall over onto the land…how are they removed.
    NO! The only solution Nassim Haramein has the answer right now! Infinate energy. Check him out.

  10. No, and the Democratic "Leaders," Brainiacs, nor Bureaucratics have offered away to create the wealth to manufacture and install. Batteries don't enable create byproducts to spread the cost over at a large enough adequate price. A lowly conservative has attempted to share this with both side of the aisle and many times on YouTube. Yet no one has nibbled. The Democratic Leadership keeps encouraging many to go down the path of bankruptcy i.e. drying to get improving the "Free Energy" collectors to fix the sources shortcomings.

  11. This video provides a thought-provoking exploration of the possibility of powering the world entirely with renewable energy. It clearly outline the immense challenges in shifting away from our heavy reliance on fossil fuels, currently at 35 billion barrels of oil annually, to an energy system based on abundant sources like sun, water, and wind. The discussion highlights both the environmental benefits of renewable energy and the technical, economic, and infrastructural hurdles that we must overcome to achieve a fully renewable future. It's an insightful look into what it will take to truly shift the global energy paradigm.

  12. As with all energy there is wast the answer is to store as much as possible and not create wast at all there is an answer and it is not in batteries regards Graham Flowers MEng

  13. Unfortunately, no one has taken the time to analyze what the world will do with billions of tons of burned-out solar panels in the mid 2040's and 50's. During this time there will be an unprecedented scramble to manage acres of unusable panels and find a place for the waste or recycle it. Like most of the world's financial management, this is another issue that will be kicked down the road for a future generation. Environmentalists seem to be in favor of this level of waste. Our grandchildren will wonder what kind of people we were.
