Topic: Our future with renewable energy. (Read 921 times)

The transition to the use of alternative energy sources is truly the call of the time and our inevitable future. Now almost all states are either developing new sources of energy consumption or are trying to implement existing developments. Humanity is being pushed towards this process by a decrease in fossil fuel reserves and dramatic climate change as a result of the traditional use of coal, gas and petroleum products as a fuel and source of energy. Previously, gas and oil corporations sharply opposed the process of searching and introducing alternative energy sources, physically eliminating inventors and destroying their inventions, but now the situation has reached a new level that can no longer be stopped.

Particularly interesting in this regard are the developments of Japanese, French and scientists from other countries on the practical application of the process of nuclear fusion as an energy source, that is, a chemical reaction that occurs in all the stars of our universe - a process during which two light atomic nuclei combine into one more a heavy core releasing enormous amounts of energy. Almost such artificial suns may appear in the next decade. This is even mentioned in the prophecies of the Bulgarian soothsayer Vanga, who predicted that people would launch several such artificial suns into low Earth orbit, which would evenly illuminate our planet all day long.

I think it is difficult to advance renewable energy at the moment, by encouraging its development it is hoped that management will be more independent, but the target will be difficult to achieve because it requires good technological progress
and it has been tested because the energy needs of users are now increasing, because in the development of renewable energy there are many obstacles faced such as limited infrastructure and limited technical expertise, because things like that require careful consideration but over time has changed this little by little but I believe In the future, all of this will definitely come true, even though it will take time to achieve all of that.

I think it's still possible, but it will take time for sure.

but along the way we can still focus on diversifying energy sources and one of them could be green hydrogen.
industry revolution toward the greener path and reducing carbon footprint will be an extensive and cost hungry effort but I think the fact that so many institutions still pushing for green energy is a good thing.
we're still too early to say that it's unrealistic, maybe within next decade we might see some significant technology advancement that allows the use of renewable energy and also boost the production of renewable energy, after all technology developing so fast.

Why increase day by day? I don't think they will always have a new gadget or appliances for that. With the rising electricity, I think it was actually decreasing, so I won't worry about the supply and reliability of electricity.

There are already renewable energy that people can use but to say that we are going to transition into it and abandon the traditional one completely can be unlikely for some reasons. For some regions or areas where traditional energy is hard to reach or their costing is high, yeah that renewable energy is more useful on them. It's perfect for them because they are not power-hungry compared to those who are living on the cities.

Since the energy needs of users increase day by day, the continuity of energy and the size of the supply are also important. The transition to renewable energy can be further accelerated with the support of states. Especially in some regions, renewable energy needs to be used. The benefits of devices used for renewable energy sources should be increased with new technologies and offered at affordable prices to those who want to use this energy. This will also benefit users and the environment by preventing energy dependency.

Although there is not a 100 percent transition to renewable energy, the rate will increase over time.

It is unrealistic to expect the world to 100% run on renewable energy. The infrastructure required for a complete transition is expensive and time consuming to implement. Renewable energy sources like solar & wind are intermittent & dependent on weather conditions which leads to fluctuations in supply. The storage & distribution of renewable energy on a large scale pose significant challenges. Some industries & regions heavily rely on non renewable sources like fossil fuels for their energy needs. Achieving a 100% renewable energy world would require substantial technological advancements, policy changes & global cooperation.

Inventions in the field of new technologies for the use of solar panels continue at an extraordinary rate.
Thus, a team of experts from ETH Zurich managed to create photovoltaic ceramics with unprecedented potential. It defies the laws of physics by being incredibly small.

Photovoltaic ceramics are a thousand times more efficient than current silicon-based solar panels. A special feature of this ceramic and its high performance characteristics is its nanostructure. The device consists of two critical components: a material that has good light absorption coefficient, and another material that has good electrical conductivity (even better than perovskite and silicon). The light absorption layer uses aluminum oxide and perovskite nanoparticles because these two substances have remarkable light absorption properties.

Perovskites are embedded in a highly stable aluminum oxide, which in turn protects them from heat, humidity and mechanical stress. When sunlight hits the ceramic, the electrons in the perovskite nanoparticles are excited and jump to a higher energy level. These excited electrons are then efficiently collected, formed into alumina crystals, and brought to the surface to create an electrical current.

This specific structure and texture allows the ceramic to evenly accumulate and store energy coming from the sun across the entire surface of the panel, and achieve a high critical reaction temperature of 1500 °C throughout the material. The new type of solar panels turned out to be 1000 times stronger than conventional silicon solar cells, since 1 sq. m of ceramics can produce the same amount of electricity as 1000 sq. m of a conventional solar battery.

Researchers suggest the new technology could deliver virtually limitless free electricity to homes and offices.

Your country uses overhead cabling? Aluminium based cables? The US Electrical grid set up ?

Here is a report on how good those are in extreme conditioning.

We are still only at the beginning of the journey to using alternative energy sources, and inventions in this area will repeatedly present us with unexpected pleasant surprises.
I recently read an article that says that the WAVJA company (USA) has developed innovative devices that can serve as analogues to modern photocells.

The developers said their devices can deliver 7.5 times the power of traditional solar panels while taking up 30 times less space. The tiny beads, ranging in size from 2.54 cm to almost 10.16 cm, can use both sunlight and artificial light to produce electricity. The balls are placed on a square-shaped device that is part of a system that converts light into electricity. Interestingly, connecting an external battery is not required, because The invention is a self-contained battery system. But if you need to connect a third-party power supply, then this can be done in various ways. If the technology can actually deliver the stated power, it will be a real breakthrough in solar energy. Therefore, of course, the future lies in new technologies for the use of alternative energy sources.

Simply burning fossil fuels to obtain a certain type of energy is man's predatory attitude towards nature as a habitat. Therefore, it is renewable energy sources that should become the norm for humans, and now we are precisely at a stage at which we have very great opportunities for their implementation in all areas of our lives.

Previously, research into renewable energy sources was hampered by fossil fuel corporations, but with their supplies running low, this obstacle is no longer expected. And it’s time, we finally take care of the environment and climate, which man has changed to his own detriment by burning coal, gas and oil products.

Yep and África leading the way.

It must be taken into account that in terms of the introduction of alternative energy sources, we are, in fact, only at the beginning of this path. The first silicon-based solar panels had an efficiency of about 16 percent; now they have an efficiency of about 25 percent. But technologies are changing relatively quickly in the direction of increasing their efficiency.

Thus, perovskite solar cells can replace conventional silicon solar panels in the foreseeable future. They are quite simple to manufacture, and at the same time they are capable of generating the same amount of electricity from the same area as silicon ones.

In a new article in the journal Solar Energy Materials and Solar Cells, NUST MISIS scientists have already presented industrial prototypes of perovskite solar cells with a record efficiency for different combinations of light colors - 36.1%. This will make it possible to generate electricity with the same average efficiency both from the Sun and from any artificial light sources. This technology is already ready for industrial implementation. Surely in the future we will have cheap and efficient solar panels. But this is only one type of possible alternative energy sources. Surely there will be others that we can’t even imagine right now.

We’ve got little choice than to get used to these renewable sources of energy if we want to have enough to fulfill our energy needs in the distant future. These fossil fuels can be depleted and it takes a really long time for it to build up again.

Sources for these renewable energy may be difficult and expensive to put up but what good project isn’t? And I bet these calls for it being so expensive are made by oil companies and its allies to dissuade the general public from buying into the idea of switching from the traditional energy source to these energy sources that can be renewable and used.
Making the switch to renewable energy sources is in a way, inevitable. But with humans, we’ll naturally be resistant to change.

Renewable energy is nowhere near as flawless as people say it is. Not all countries and locations can use it. Energy generation occurs at certain times of the day, not around the clock. There are also problems with the capacity of the renewable energy source and the high cost of production

In my opinion, we have no other choice than to massively introduce renewable energy sources and try to replace traditional ones with them - oil, gas and coal, which cause irreparable damage to the environment and dramatically change the climate on our planet. Talk about it being expensive, difficult and not so fast is absolutely unfounded. After all, we are actually talking about the survival of humanity.
In addition, alternative energy sources have been developed relatively recently, but are being improved at a rapid pace and their cost is falling. I think that over time they will almost completely replace traditional fossil energy sources and this will be very cool.

Coal is a very specific resource. And the roots of "preference" are historical. I recommend reading the history of Britain, and the very difficult decisions associated with mine closures. The fact is that coal mining by the 20th century used huge numbers of workers. In many countries and in many mines, mining is done purely by hand, and that means thousands and thousands of people, and even entire small towns. Plus - the cost of coal and the cost of its purchase or subsidy programs - a very tidbit for those who trade in coal. That's why some countries continue to exploit cheap labor, making money on it, while closing the mines will not only deprive miners of income, but also create very significant social tensions. Social tensions in the mining regions, for example, are the main reason why developed countries subsidize and support the coal industry. Just imagine what would happen if 100.000 miners who do not know anything but coal mining and the saddest thing is that they do not want to change anything in their lives.

The main obstacle and actually the first step that must be taken is this which is very difficult. Namely infrastructure development which is quite expensive and requires quite prolonged development until finally everything is ready in every area from big cities to remote areas. But actually the expensive financing is also equivalent to financing fossil fuel infrastructure too. Imagine if we started from a primitive state and started to discover fossil energy and we built the infrastructure. Of course, even then everything will feel very expensive. But still, all this was done slowly so that in the end development was evenly distributed in all regions and everyone began to use and get the benefits. So the development of renewable energy infrastructure will be the same. Yes, the costs will seem expensive, but when development continues slowly and gradually, without realizing it, all the infrastructure will be spread out and ready to be used.

The point is that all development will definitely be very expensive.
But because of the urgent need, everything will still be built, even if it has to be done little by little. Moreover, currently we are truly witnessing the destruction of nature. Where the climate is becoming hot due to global warming. So all countries are required to adopt renewable energy structurally and slowly. step by step. And ultimately everyone who currently even rejects renewable energy will eventually accept it and use it if the infrastructure is in place.

The point is that everything will ultimately use renewable energy. But it may take years or even decades to completely switch to renewable energy. But fossil energy will probably still exist and will only be used in limited portions.

Yes, we can. If you look at the Kardashev scale, it is possible that the world is dependent on renewable energy sources. On that scale, our world will be able to depend on renewable energy sources on a scale of 1 and now we are on a scale of 0.7, meaning we are approaching civilization where we can utilize all renewable resources on the earth and the sun. Maybe we will not be able to completely get rid of fossil energy because it is also needed to make our world warmer, but perhaps the amount will be drastically reduced and its use will be more restricted.

government around the world always prefer coal for god knows reason maybe they consider coal to be more cheaper thats why they want it but we all know the mining activities as well as the process of generating power causes massive pollution, but then again the renewable sources of energy are still in its premature stage i think it'd be better if someone like elon could somehow innovate and invent better solution for renewable energy thats both easy to mantain, cheap and could generate massive amount of energy because the biggest hurdle with using something like solar panel is that most of the time it doesn't produce that much energy and requires a lot of solar panel to power one big household consistently.
at the end of the day its government that honestly should incentivizes the use of renewable energies.

The initial investment is pretty expensive, though. It's worthful on long term (decades), but you need a very large budget to have access to this technology, unless the government creates a financing program, so you can pay for it in monthly parcels for several years. However, they don't do this, because it would affect important sectors of society, like fossil energy production and the public companies which sell energy to the population at very expensive costs.

You are right when you say about the private sector, as the only way we can have access to renewable energy sources is through paying very expensive costs to them.

That allows only a very slight portion of the society to adopt green energy, consequently not allowing the world to benefit from its advantages in large scale. I truly believe there is a lobby forbidding green energy adoption from growing in high intensity right now, what is a pitty, although there is nothing we can do about it, besides paying the price it costs.
