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.

You didn’t talk about wind.
I love this video. It is a good explanation for a grade school aptitude to understand the general challenges of renewable energy. I am one of the engineers working on this problem… I have been for the past 30 years.
Yes, it already does. All energy is renewable and came from the sun. The energy on earth will last as long as our sun. The renewables construct is nonsense.
climate emergency really try Googling CO2 levels an average global temperature estimates for when the dinosaurs were alive .
acid rain
plastic bags will save the trees ( now they burn trees in biomass plants) its green energy you know.
hole in the ozone
global cooling
global warming
climate emergency
electric cars are cleaner than gas cars
you want to save the planet !!!! my parents still have the same fridge stove washer and dryer that they've had for the last 42 years I can't get a fridge the last five.
The answer for the future lies in nuclear power augmented by solar, wind, biomass, and tidal power.
Anything that moves contains energy. You just have to learn how to extract it.
No, sadly.
Without subsidies from oil and coal .
the scales where off by 3 mm
🎯 Key points for quick navigation:
Fossil fuel reserves are limited and running out, prompting the need for renewable energy sources.
Renewable energy sources like sun, water, and wind are abundant and won't be depleted over time.
Transitioning to 100% renewable energy is challenging due to cost and accessibility issues.
Technology exists to capture energy from renewables, but efficiency and energy transportation are barriers.
Superconductors could help transport electricity efficiently but currently require low temperatures.
Storing renewable energy in a transportable form is a scientific challenge, especially for liquid fuels like aviation.
Efficient ways to convert solar energy into chemical energy are being explored but are not market-ready yet.
Transitioning to 100% renewable energy requires creativity, innovation, and incentives across technology, economics, and politics.

Yes.. Using my new horizontal hydro gravity.
It's 30% now! Let's go!

Short answer ……NOPE!..
.There I just saved an hour of your life you would have never gotten back…your welcome.
I'm buying ted
Use solar
Use Tesla tech
1:00 Renewables are already cheaper than fossil fuels, way cheaper, in fact, the two are not even close…
4:17 Keep in mind though that EVs use around 90% of the energy while combustion engines loose most of the energy in the fuel through heat etc. having well below 50% efficiency.
Which is the ROOT problem: YOLO CONSUMERISM, or non renewable energy sources?
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.
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
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.

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.
Meeeee
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.
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
you know super conductors right than if you nead to get i cool than use the ocean
