- 7 Types of Renewable Energy
Solar
Solar energy is derived by capturing radiant energy from sunlight and converting it into heat, electricity, or hot water.
With the technology to harvest it, there is a limitless supply of solar energy, meaning it could render fossil fuels obsolete.
Wind
Wind farms capture the energy of wind flow by using turbines and converting it into electricity.
Wind energy is a clean energy source, which means that it doesn’t pollute the air like other forms of energy.
Wind energy doesn’t produce carbon dioxide, or release any harmful products that can cause environmental degradation or negatively affect human health like smog, acid rain, or other heat-trapping gases.
Hydroelectric
Water flows through the dam’s turbines to produce electricity, known as pumped-storage hydropower.
Hydroelectric power is very versatile and can be generated using both large scale projects, like the Hoover Dam, and small scale projects like underwater turbines and lower dams on small rivers and streams.
Geothermal
Geothermal heat is heat that is trapped beneath the earth’s crust from the formation of the Earth 4.5 billion years ago and from radioactive decay.
Geothermal energy is not as common as other types of renewable energy sources, but it has a significant potential for energy supply.
Geothermal energy is naturally replenished and therefore does not run a risk of depleting (on a human timescale).
Ocean
The ocean can produce two types of energy: thermal and mechanical.
Ocean thermal energy relies on warm water surface temperatures to generate energy through a variety of different systems.
Ocean mechanical energy uses the ebbs and flows of the tides to generate energy, which is created by the earth’s rotation and gravity from the moon.
Unlike other forms of renewable energy, wave energy is predictable and it’s easy to estimate the amount of energy that will be produced.
This type of renewable energy is also abundant, the most populated cities tend to be near oceans and harbors, making it easier to harness this energy for the local population.
Hydrogen
Hydrogen needs to be combined with other elements, such as oxygen to make water as it does not occur naturally as a gas on its own.
When hydrogen is separated from another element it can be used for both fuel and electricity.
Hydrogen can be used as a clean burning fuel, which leads to less pollution and a cleaner environment.
It can also be used for fuel cells which are similar to batteries and can be used for powering an electric motor.
Biomass
Bioenergy is a renewable energy derived from biomass.
Biomass is organic matter that comes from recently living plants and organisms.
The use of biomass in energy production creates carbon dioxide that is put into the air, but the regeneration of plants consumes the same amount of carbon dioxide, which is said to create a balanced atmosphere.
Biomass can be used in a number of different ways in our daily lives, not only for personal use, but businesses as well.

@see ya never that serious
👍
the stark contrast between an energic bgm and a robotic voiceover is golden
Thank you for your support.
Nice video, but get rid of the annoying music! It's distracting.
There may be ways for every household and every neighborhood to produce their own energy.
Thank you for sharing informative videos!
Thanks for your explanation 👍
I really learnt in this video
1:50 is it possible to create something by combining both sources to make an infinite supply? For example use a motor to help provide artificial wind for wind turbines and use the energy from the wind turbines to help charge/power the motor?
Yeah good idea
Louis Michaud is working on this by trying to create and harness tornados.
@@abacadayI too am working on making a giant hair dryer that will blow wind.
I did the blueprints, but it turns out the blow dryer uses way more energy than the wind it's supposed to produce.
If you had 100% efficiency (in reality wind turbines have no more than 40% energy efficiency max), than your wind generator would require at least as much energy as the wind tubrines can generate for it. So your idea is not sustainable.
However, one thing that you could do in theory is to build key infrastructure to generate zones with huge amount of wind, but that would require you to move mountains... Litterally... Or to cover many thousands of square miles of solar panels to change a local ecosystem so that a neighbouring area has more wind. But if you install thousands of square miles of solar panels, it is assumed that you are already able to generate more energy than your country needs so you wouldn't need those wind turbines anymore...
Between these & hemp's uses - the future of a sustainable world is looking very possible.
Zero point energy exists and would be the ultimate game changer, but me thinks the controllers will never allow these. So for now, yeah hemp and this lot I guess.
I love the solar ovens I have purchased from go sun.
Yeah it's a good brand
Somethings that could be improved with most renewable energy sources is that most turbines use lubricant that comes from fossil fuels. Also after awhile, they need to be moved into landfills. 👍
1. Lubricant can also be bio oil
2. Those quantities are near negligeable compared to burning fossil fuels for energy
3. Turbines are steel, and steel is one of the easist and most recycled materials in the world, those turbines won't see a landfill anytime soon.
who else is hear bc of their teacher?
Thank you
me lol
Yep
me
us both
Very informative content. Music ist too loud and make it hard to concentrate sometimes.
*Tidal wave energy* is a renewable pollution free eco friendly energy sources 😁👍👍
SUPERB EXPLANATION. THANKS
Thank you !
Thank you for your support
The beauty of renewables is that they can be scaled down for small isolated communities which will never be linked to the main power grids such as floating hydrokinetic platforms which could be anchored on rivers and robust streams without damming the waterway.
The problem is no of this shit works efficiently dummy.
ua-cam.com/users/shortsstf2YrznkZU?feature=share
We need thesis title for our subject, it needs to be a renewable energy type of thesis. Any advise?
I have theories on how we can improve this renewable and might achieve the efficiency we wanted.
1. Wireless grid for outer space solar panel
2. Floating Turbine
3. Improvised Tesla Turbine for Hydroelectric
4. Earthquake preventor for Geothermal
5. Hybrid water turbine that will use salt and the current in the ocean
6.improvised generator machine for hydrogen
7. Genetically modified Bamboo that will triple its growth rate for biomass energy.
8. Machine that captures smoke and turn back to coal again.
9. Machine that recycles nuclear waste
We already discovered all energy we need, we just need a better technology for sustainability.
These are some great ideas,I'd love to see you or someone try this.
how would we harvest energy generated by a solar panel grid in space? I like the idea but I don't think we have the tech for that right now
Machine that recycles nuclear waste? It’s radioactive, harmful to humans (life in general) and toxic for 240,000 years... why would you want to recycle that shit lol
Some great ideas an I watch it tell prepare my self for later studies
@@patzoid2782 This can be achieved by shooting lasers from this space grid. China wants to test this idea, but in practice it's not sustainable. You need huge quantities of energy to get those panels up there, you get only very little energy in return, and I'm not even mentioning the ethics. Would you like to live in a world where you see huge beams of lasers in the horizon? We already have nimbys complaining about wind turbines only a few hundred feet tall, imagine lasers many kilometers long...
This is informative, thanks for sharing! ❤
Renewable energy is so cool when harvested! So many jobs!

Thank you so much! I used this for school and it was very useful 👍
You're welcome. Thank you for your support.
Nice video:) the future belongs to alternative energy!
Yeah, Thank you for your support
I mean auternitive energy should be the primary energy hence it's the least harmful isnt the goal to become a a Eco freindly society
1.Duration of the solar panel is about 20 years. And here we encounter another problem. It takes time to install enough solar panels in the world and to meet energy needs. When this installation process is complete, then it will be necessary to replace those that were initially installed. Which means that the process never ends, but is constantly spinning in a circle.
These plates, which have served their purpose, are thrown away in landfills. Waste from solar panels is 300 times more toxic than nuclear waste and requires special disposal. But since it costs more than production, we decided not to bother too much, so we send used boards to landfills in poor countries. Like most unwanted waste in the world. So much for the way it works under the quotes of developed countries. Today, no country in the world has regulations to dispose of them.
You got your data from a news article sponsored by fossil fuels, or a journalist who got their information from such a source without verifying it.
Firstly, solar panels have a life expectancy much greater than 20 years. After 20 years, they still generate on average around 80 to 90% of their initial power from day 1, depending on the climate they have been installed in and how well they have been maintained. You could still use the very same old solar panels after 40 years and they would still work. In reality, they are only given a 20 year life expectancy for one simple reason: garantee. Many things can happen after 20 years, and companies producing and installing those panels don't want to take too much risk for business. Another reason is also because solar panels become a little less effective over time, and loosing 10% of your energy output is 10% less money you're making selling your electricity. Not to mention that newer generations of solar panels that are cheaper and more effective can dominate the market int the future, incentivizing the replacement of the old even more. But still, you could in theory have a solar parc lasting for 30 years and still have a great energy output. And that only accounts for PHOTOVOLTAIC solar panels. You can also use THERMAL solar panels, which is litterally just some darn mirrors that can last for centuries without needing any replacement...
Secondly, solar panels are among the easiest things to install in the world. I have absolutely no clue where you got your information that they were complicated to install. I'm not even going to debate this one, I'll just leave you with one challenge: name me ONE energy source, ANY energy souce you can think of, that is easier to install than solar.
Thirdly, it is really sad that solar panels are not recycled as much as they should be, I'll admit to that, especially since more than 96% of their components can be recycled. But that shouldn't be too much of a problem in the future. Lead batteries from cars also used to be thrown in landfills before regulations forced recycling, and that was at a time well before climate activism was a thing. So I'm optimistic that the same will happen for solar panels too. But picture this: we could in theory reuse 96% of solar panels after 30 years of use. So a same solar parc could last for well over a century with only less than 15% of its materials lost and thrown in landfills. And again, this is only accounting for photovoltaic.
Lastly, solar panels are NOT 300 times more toxic than nuclear waste. It's literally just glass (more than 90% of it), sillicium, aluminum for the structure, and the one thing that is "toxic" are the some rare earth metals contained in it (not even a handful of a percent). It is certainly not as harmful as deadly radiations from nuclear waste. And if that STILL poses a problem for you, nothing is stopping you from vitrifying the tiny amounts of toxic metals in solar panels, and then dispose of it safely in uninhabited desert places hundreds of feet deep underground where it wont harm plant nor wildlife, basically exactly what is being done with nuclear waste... Or just use thermal solar energy and get rid of that problem altogether...

Great video - thanks:)
May I cite this video for a lesson I am developing for my nonprofit?
Yes you can
Thank you
Great fantastic video
thank you
Thank you for your support
music irritates
yeah sorry for that. Problem solved for new videos.
There's so many renewable sources of energy I can't belive we haven't completly switched. Poor, poor earth
yeah that's really unfortunate
Good presentation for a starter.
Is what he says written down somewhere so i can read it? becouse the letterg go by very fast
Im having class right now and they are you this video lol
thank u
It's a great project
Thank you for your support
So which one should we use?
It depends on many things: price, region, etc...
Oil and gas

There Is No Shortage of Energy; There Is Shortage of Normalcy
Despite increased production of energy from renewable sources, and despite the slowdown in car manufacturing, oil prices are skyrocketing. Even though fewer power plants still burn coal, coal prices are skyrocketing, as well. Natural gas prices, too, are going through the roof, and energy demand seems to outpace supply in every country and in every form of energy. Have Earth’s energy sources dwindled so drastically in a matter of months? The answer is a resounding “No!” There is no shortage of energy; there is a serious shortage of normalcy in human relations. I hope the current crisis will put some sense into humanity’s insane consumption.
The energy crunch indicates that we are over consuming. We are producing too much, throwing the excess production to the trash, polluting the ground, the air, and the water, and then we are complaining that we do not have enough. It is about as sane as killing one’s parents and then pleading for the court’s mercy because I’ve recently been orphaned.
It is time we reconsider everything we produce-how we divide production, profits, and goods, which services are necessary and which are redundant, and most importantly, how we treat one another. The goal of this process should be clear to everyone: survival.
There is no ulterior motive, no attempt to dominate or deprive anyone of power or wealth. It is simply that reality is forcing us to take all of humanity and the entire planet into consideration. If we don’t, our entire civilization will collapse like a deck of cards.
Since we still do not understand it and insist on running things the way we have always been running them-through power games-I anticipate a very cold and gloomy winter for the northern hemisphere. The energy crunch will leave many in dark and cold houses; there will be no gas for cars, and renewable energy will not replace traditional sources since there will be little sun during the winter. I hope that at least, it will make us rethink our values. If it doesn’t, next summer will be even worse than the awful summer that just ended.
I know that many people are counting on the promise of renewable energy to solve the energy problems of humanity. I think they are mistaken. There is plenty of energy, far more than we really need. We could cut emissions by at least half tomorrow. But the more we have, the hungrier we become, so our thirst for energy will never be satiated, and we will never stop exploiting the planet or each other until we reeducate ourselves and start being humane toward each other.
We have been behaving like spoiled brats whose parents buy them whatever they want. Now, our parents have run out of money and our childhood is over. It is time for us to mature and conduct ourselves like responsible adults, caring for all of humanity the way a mother cares for her entire family. If we think like a family, we will achieve normalcy.

A lot of information in a short format.
Thx for making this video, it really helped me understand!❤️
Nice informative video just need to make new one with more details there is also another form of renewable energy the thermal wells which are really expensive to build but it will come back as the other energies still rising. Btw that music was really annoying to listen to , way too loud as well.

We need to open up more coal-fired power plants nuclear energy
You realize 90% of the items you are surrounded by comes from fossil fuels. I weep for the ignorant future
yeah that's unfortunate, but we are changing that slowly
@@ecomasteryproject8322 I don’t want anyone to be confused. I’m extremely Pro oil and gas as in I work in the industry and enjoy what I do.
I drive very big, coal rolling diesels. That being said. I do agree with fact that we have to move toward a greener energy. It’s just at the moment this movement for “Green” is trying to move quicker then it should. Oil and Gas will be a valued commodity for many moons to come. If the “Green” pushes to hard you will make it unfeasible and unaffordable for either side to produce what we need. This is just my option.
The music is really distracting ☹️
Energy is based
Don't understand what you mean

Nuclear energy??
Green energy fact: if we put all green energy subsidies together in one-dollar bills and burn them, we could generate more electricity than has been produced by subsidized green energy
Every day we have new solutions coming from science and technology so we hope that the future will be better
3h are left to do the gcse exam

What is that bad annoying music in the background?!!!
Conservation is key also.
Olz avoid music
There's scope for every type of houses and businesses to move to a cleaner source of power. Starting from solar batteries to huge wind turbines, the choices and applications of renewable energy are endless. There are many green companies that help accelerate clean energy in developing nations, one of them is Distributed Energy (de.energy). Nice to spend sometime to get to know players helping clean energy adoption.
hey school friends!
3.Now let's look at the downside of hydropower. 65% of the world's largest rivers are blocked by hydroelectric power plants. At the same time, accidents and dam breaks threaten human lives, and the planet’s ecology suffers. Hydropower plants directly affect the Earth's bowels - tons of water from reservoirs press on tectonic plates causing earthquakes, which are therefore caused by man.
The hydropower plant stops the natural flow of organic matter needed for vegetation growth. There is a well-known story: when the Nile River flooded and then receded, it enabled a good crop yield. There is another major environmental impact of hydropower. And that is the change of all watercourses in the area. As soon as the water stops and raises its level, it has a big impact. Since we live in a consumer society, it doesn’t matter what the impact is on the environment and people’s lives, as long as profits are made.
We remain convinced that alternative sources will improve the environment and solve the problem of climate change. Why?
