These are ten most promising alternative energy sources of tomorrow.

It’s a really exciting time to be alive. We have a front row seat to the only known transformation of a world powered by dirty fossil fuels, to a planet that gets its energy from renewable, clean sources. It’s happening just once, right now.

VOTE to support alternative energy in the USA!!!
You have confused wave with tidal power.

Lockheed martin with infinite energy? Its war of the worlds... energy weapons and war monger stocks climbing to high heavens so that we can create planet hell
you forgot the top 2 most powerful source of energy.

The one that turn india's smell into energy.

the other one, that turn noise from kindergarden into energy.
Robert Shackleferd
Algae, bio fuels, human power, wind farms???? and hydrogen mentioned in the first part is not a fuel source but a carrier of energy.

There's no such thing called clean energy . People please be practical .
Sabet Ibrahim
Some information is wrong and misleading .

11. The power of Manure.

The solar power plant in California that is mentioned at about the 7:26 mark is one of the most expensive energy power plants, that if it was not prompted up by the government, would have been shut down by now or never would have been built. It is the perfect example of how we can build something as a proof of concept, and then we should learn that it was a bad idea and never do it again. It cost about 10,000 times more to buy electricity from that power plant than it does from more traditional solar power plants. It is also important to state that solar is still the most expensive way to generate electricity. Also, growing by 500% or f times is saying that solar went from .26% of the U.S. energy production to 1.3% of the U.S. energy production, which is not a bad thing, I just think that we should be honest with the solar growth. I cold discuss many other points in this video, however, it is best to say that there are many cool ideas out there, however, the technologies are not ready for massive implementation.

lot of this is outdated and debunked.
Nuclear fission is way cleaner then fussion you mixed up the two. The msr reactor is better if combined with thorium your wrong. The "fast reactor" is not safe. The Molten salt reactor is better. Yet its being swept away from the market due to oil lobbying.

These problems have already been solved since the 1920s but sadly our government re-education camps known as public schools keep regurgitating all of these systems you mention in this video to each generation as just around the corner.

I won't hold my breath waiting for any of these.
Drilling very deep is well understood.
So why can't pressure (or temperature) at depth be a source of power-generation?

Getting our consumption under control is a better way to manage demand.
Floodlit buildings, idiotic and makes me wonder why I bother trying to save energy when this is going on.
Allen West
Using pressure to make electricity is called Piezoelectricity and it'd been used for a LONG time. Piezoelectric Plates are cheap , and used in pressure sensor ... It's crystal power !
"Piezoelectricity is the electric charge that accumulates in certain solid materials (such as crystals, certain ceramics, and biological matter such as bone, DNA and various proteins) in response to applied mechanical stress. The word piezoelectricity means electricity resulting from pressure and latent heat."

Solar powered balloons 2 cords and you can gather energy rain or shine best design can fuel 45000 homes change that so you can have 100% energy with no bird killing and placed over the ocean a good design and they can last 100s if not thousands of years and be a constant energy source

Graphene Supercapacitors Are About To Change Top 10 Energy Sources of the Future 7 months ago   09:18


We live our lives through portable devices, and the race is on to create better energy storage for those devices. Could graphene supercapacitors be the holy grail?

Ted-Ed, how batteries work

BASF Lithium Ion

Impossible Battery - Seeker



So before I can explain how super capacitors will fix this, let’s back up and explain how batteries work in the first place.

To make it simple, batteries work by moving electrons from a negatively charged material called an anode to a positively charged material called the cathode, and the device siphons off those electrons to power the device.

For instance, nickel cadmium batteries use a nickel oxide cathode and a cadmium anode. Hence the name.

This is a chemical process called oxidation that involves an electrolyte layer sandwiched between the electrodes.

In the case of the nickel cadmium batteries, they use potassium hydroxide as the electrolyte.

But this is a one-shot deal. The chemical reaction releases the electrons, but there’s no way to re-introduce electrons into the equation.

So they’re not rechargeable. And for a world increasingly reliant on portable devices, that’s just not good enough.

Enter Lithium-Ion batteries, which were developed in the 1970’s by John B. Goodenough. That’s his real name. That’s not a joke.

Lithium ion batteries have a cathode made of lithium, duh, and an anode made of carbon, again with an electrolyte between the layers to facilitate the reaction.

The difference is lithium will absorb more electrons, so it can be recharged. But it is still a chemical reaction, so it can only reintroduce those electrons at a certain charge rate.

Super capacitors work differently. Instead of using a chemical reaction to make electrons flow, also called and electrochemical process, they use static electricity, or an electrostatic process.

Now, capacitors have been in our computers for decades, and they work by holding opposite charges between two metallic plates separated by a dielectric material.

Super capacitors, as you may have already figured out, are larger versions of capacitors that use a double layer to hold more energy. In fact they’re sometimes called double-layer capacitors.

And the cool thing about them is that since the electricity is static and not chemical, there’s far less resistance to the charge. In fact, it’s almost instantaneous.

The problem is, they don’t hold that much energy. You need a vast amount of surface area to hold enough energy to make them really useful.

So Lithium Ion batteries are very energy dense, meaning they hold a lot more stored energy, but super capacitors are very power dense, meaning the transfer the energy much faster.

If, theoretically, you could create super capacitors that could hold as much as a lithium ion battery, you’d have cell phones that could recharge in seconds and it would be good for the rest of the day.

And dare we dream it? An EV car that fully charges faster than it takes to pump gas.

There is one material that could make this dream a reality. It’s called graphene.

Graphene is basically a one-atom thick lattice of carbon atoms that has some ridiculous properties. It’s 200 times stronger than steel, but incredibly light, biodegradable, biocompatible, meaning it can be used in the human body.

They say it can be used to desalinate sea water, make space elevators, and form the basis for supercomputers, but for our purposes, it also happens to be one of the most electrically capacitive substances known to man.

It has the same energy density as lithium ion batteries with the power density of super capacitors. And since it’s only one atom thick, you can pack a ton of surface area into a small space.

With any luck, in the next 10-15 years, we’ll have super capacitor batteries that can handle energy densities at industrial scales giving us quick, plentiful electricity whenever we need it.
