only 10% of the worldwide electricity production comes from nuclear plants. if you want to expand that percentage, the amount of waste and the potential of a nuclear accident naturally rises. almost all of the current reactors are in wealthy countries that can invest in safety. for widespread use the dangers have to be minimized, otherwise the risk isnt worth the gain.

@@Istaki0 My safety comment is based on normalized mortality rates, deaths per megawatt, in order to adjust for scaling needs. Nuclear power is extremely safe, regulation is much tighter on nuclear reactors than on other power plant types so you would save lives by replacing coal and natural gas plants with nuclear reactors to say nothing of the carbon footprint benefits. You are correct in the placement of reactors but in an idealized situation where we are addressing global electricity needs we can probably assume that the richer countries are footing the bill. Access to stable, reliable power also saves lives. Electricity allows for water purification and refrigeration for medicine, both of which dramatically increase quality of life and reduce mortality. Building a nuclear reactor in an area that currently has no access to stable power would probably save lives on net, and if it's replacing fossil fuels it will save even more.

Risk=Probability x Severity. Nuclear accidents may not occur often (probability), but it only takes one to contaminate the environment for hundreds of years (severity). Check Japan 2011, even today they're nowhere near in controlling the situation (current estimate is for 2050). Entire cities reduced to ghost towns and they're considering throwing the radioactive waste (that continues to pile up) to the ocean because it's too much. The risk is very high. It definitely needs to be made safer.

There are some problems with deserts though. While it may seem a good idea to install solar panels in a place in which the sun is strong and clouds are rare, there are actually a few caveats. The first is that solar panels don't work well in very hot places which is usually the case in deserts, keeping the temperatures around 20°C helps their performance and reduces the cost of cooling systems. This is why floating technology for the panels is popping up in some places, the water below keeps the panels cool and its reflection increases the amount of incident light on the panels. Second is the amount of dust and sand in a desert. Solar panels in such a dusty place would have to be cleaned very often - you could say you would make more jobs for cleaners, but the cost of energy will be higher - and duststorms might damage some equipment even though they are made to last in those conditions.

They even failed to include hydroelectric, the only one that has had its chance to properly prove and cement itself as an alternative. I don't mind them missing out on geothermal considering that is the most dependent on location. I'm not against any of them besides fossil fuels, and even then I am understanding and well aware of its incredibly useful strengths. I don't hate it I just know that its use has be reduced in order to lower the geological load. It's like salt, to much and it's bad, but to little and there's something missing. I am for a combination and moderation of multiple solutions.

I think it’s important to note that nuclear energy only takes up the amount of space it does for the amount of energy it produces because we only use uranium as nuclear fuel, which is highly inefficient compared to what other nuclear fuel options, like thorium has to offer - which uses only about 1/5 the land that our current uranium-235 reactors use And in case you were wondering, the ONLY reason for why we don’t already use thorium to produce energy instead of uranium is because the radioactive byproduct that is made from the fission of thorium cannot be used to make nuclear bombs due to it being a more stable element

Electrical engineer here. It does not seem that you are taking dispatchability into your cost and land-use calculations. If the sun doesn't shine and the wind doesn't blow at the right times (which happens very frequently), you must have backup generation or storage to maintain grid stability. Backup generation is, much of the time, a fossil fuel and storage is extremely expensive and/or very land intensive. In my opinion this puts nuclear clearly ahead of the rest.

If you are willing to spend money on safety and waste disposal, yes. of course, nuclear fusion would eliminate these concerns. renewables and hydro power have the advantage that they arent expensive and can be used almost everywhere to some extent, especially in places were it isnt cost effective to build a big power plant.

Not everyone lives in a house. Apartments have hundreds of people who need electricity but only a large house or 3's worth of roof. And they need electricity at night too, so you need space to build all the batteries or hydrogen storage tanks or whatever it is you use to store the solar power

This channel so good to learn from. : )

You didn't mention the space and resources consumed by the batteries that renewables require, so I assume you didn't account for it. Another thing people too often ignore is the waste generated by retired renewable power stations.

And that's why it's imperative to evaluate things from all sides. TBH the first two minutes are a good argument for fossil fuels supporters.

Wait 'til you get into carbon capture tech... many countries have lots of coal resources that by greens' ideas would be laid to rest while becoming reliant on others for power. The politics of that is... stinky at best.

An almost honest conversation. Where's the part about needing batteries in order for solar/wind to replace nuclear/fossil fuels?

They talk a lot more about batteries in their battery video in this series. I think they covered batteries extensively there. Might be a future video linking batteries and renewable energies tightly.

Good video. Really loved it

"Stick Figure Tropical Frogs Have An Energy Crisis While An Oddly Proportioned Man Parks His Mini-Car Nearby And Watches" is my favorite TedEd video.

we need to take into consideration that renewable energy can also affect the world because solar power can absorb to much heat if to many are built and wind turbines can reduce winds causing weather changes and hydroelectricity can destroy certain environments

The emphasis on safety in the case of nuclear can be very misleading. Nuclear power is probably THE safest and most efficient in the long run....just a handful of big incidents caused by a very irresponsible few have spoiled it's image.

Trading systems allow you to limit the factor of emotional influence on decision-making,

The space problem for solar cells can be partially solved if you increase the efficiency, today's cells turn 20% of the solar energy into electricity. There are cells that reach up to 40%, but they are not cheap. By the way, are we going to build the mini reactors that have been talked about for so many years?

What about covering the great sahara ( the great desert ) with solar panels ? I mean it’s literally a desert and it has no use and we can just turn it into something useful and a power source

Good as always u never make me down man love your vids

We need Tidal and Hydroelectric in there too!

As someone from The Bahamas, I love how he used Grand Bahama as a reference!

Great video!

The best video in a very long time

Mining of coal and uranium was included as part of space used, what about mining metals to produse wind turbines or solar? Also nuclear is not unsafe and maybe expensive to build but cheap to operate.

Solar panels in practice can take very little area. Rooftops are "free", and in principle non-rooftop solar can be used for agrivoltaics - grass for livestock or growing plants that thrive with less sunshine. Many desert areas could be reclaimed for panels if partial shading was available.
