The technology is not advanced enough or cheap enough to get a good ROI if you invest in solar for the average consumer. You might have hydroelectric power or windmills used in isolation in some countries if the burden of electricity is small, but larger countries don't have any chance at switching to renewable any time soon, so perhaps the answer is what you mean by "the future."

Nuclear power should be in the near future, though. The main problem with nuclear is what to do with the resulting waste, but it seems the carbon foot print of disposing nuclear waste is lower than that of fossil fuels.

I think renewable energy is just a temporary solution to get rid of fossil energy and nuclear power. Humans will have to find a new form of energy to serve humanity to develop to a higher and more sustainable level. We are hoping for scientific and technical achievements.
What form of energy we are talking about, solar energy can be implementing in places where they get ample sunlight and it wont help in countries where there is freezing cold all round the year, but the major problem i see with the solar energy is that the battery technology has not undergone any major changes for decades and they have a life span of 5 to 8 years maximum and even if i want to move to solar energy the amount of money i need to shell out for maintenance and replace batteries every 5 to 8 years will be huge.

Bitcoin mining consumes approximately 0.50% of all electricity consumption worldwide. That's more electricity than the whole of Washington state on a yearly basis. If we also take into account other, Altcoin mining operations, this number is severely larger. It would certainly be more beneficial (And more profitable) if these mining operations were using solar panels, or another form of renewable energy source.
The tricky point there is the fact that mining uses energy, and yes that is correct their energy consumption is high but they are not the ones that generate that energy at all. They are not asking if it is solar or hydro or wind or oil or whatever, they just use it. It means that it is the problem of energy companies to stop with oil, and work on getting renewable energy everywhere around the world. If they could do that then miners would be using renewable energy as well.

So, the problem is not that miners are using too much energy, it is that they are given the wrong type of energy to begin with. Thankfully world is going more and more green every year, not enough yet, but still greener is a good start.

New energy is increasingly difficult to find, if we don't care about renewing energy then we can be sure that the world will experience big problems, maybe the price of energy is so expensive that only the rich can pay, now we must support energy renewal programs so that they can save the future of our children and grandchildren.
As what we have now, I think that the current products for renewable energy generators are already cheap for an average family so I don't think that the companies would pursue to make an expensive one plus there's a lot of inventions in the renewable energy sector that makes things much cheaper to the point that anyone can provide it.

Our dependency on them must be decreased, in order to sustain them for the future.
If we talk about reducing our dependence on fossil fuels, then this is the same as requiring enormous research and development.  However, I highly doubt it can diminish in a short amount of time.  It takes an extra approach and a very long time to change the people's habits that have taken root.  If fossil materials are replaced, the solution is electricity, but electricity also requires coal for its basic material.
That's true, it is indeed a great idea to produce energy from renewable sources, however I don't think we have the technology to apply it on a large scale, yet. I believe that we'll have positive results the upcoming decades, increasing our renewable sources capacity will also decrease our dependency on fossil fuels, thus, preserving them for an extended period.
I think the technology must already exist but it seems that it is only limited so not all of them can implement it,
I hope that this goal can be achieved because after all by using renewable energy it can protect the earth too

- Maybe it's just a way to deal with the temporary dangers of energy sources for the future but as a best way, it seems to be recognized as our future because the scientific world has been pursuing for many years in the research of other energy sources that can replace and serve humanity, the result is still that depletion will be a problem that happens over time. Therefore, renewables are almost hitting the nature of the weak points of energy sources, renewables are also simpler when there are quite a lot of impurities and wastes that can be used as fuel.
There are plenty of ways to create energy, nuclear is one of the most effective, but dangerous nonetheless, it's a practice that should slowly be diminished, for the sake of our safety. As another user mentioned above, there are a variety of renewable sources, which may and probably will not replace fossil fuels in the next upcoming decades, however, our dependency on them must be decreased, in order to sustain them for the future.

I think that renewables energies are definitely the future for us. It is not only crucial for cryptocurrency mining, but also for the future of our world and environment. There are so many human-induced environmental problems now and fossil fuels can be one of the examples for this. We must completely end using this energy source as soon as possible and we must start using green energies directly. Otherwise, we won't have a world which we will be able to live in like always.

The world has been depending on burning fossil fuels for energy, throughout all these years. With dependence on fossil fuels, soon enough these finite materials will be depleted. Not only that, but it also has adverse effects for the environment, everything from air to ocean and land pollution.

Fossil fuels include, coil, oil and natural gas, with the latter being cleaner that oil and coal in terms of emissions. Let's also keep in mind how strenuous of a process it is to extract oil, promoting environmental disasters.

Most common renewable energy sources include, solar energy, wind energy, hydro energy, tidal energy and a few others.

The big question here is, can the world be 100% dependent on renewable energy sources? How can that be achieved and are they sustainable?

Renewable is future of human life. It is clean. One major concern I have is smogs. We know how harmful it is to humans, the environment and the economy. Renewable energy will definitely improve the air quality in our cities. The pros outweighs the cons when considering switching to clean energy.

I strongly believe that renewable energies are the future especially in terms of cryptocurrencies. As you all know, fossil fuels have been used for cryptocurrency mining for a long time. We are seeing new that renewable energies are starting to be used. And in the future, renewable energies must be used by the majority to have a better environment and better world as a result. Otherwise, there is a really worrying future waiting for people.
Bitcoin mining consumes approximately 0.50% of all electricity consumption worldwide. That's more electricity than the whole of Washington state on a yearly basis.

This is also an important factor, fossil fuels are being rapidly draining in the past few years, I don't think we have that much time. An interesting example can be found through Worldometers.info, showing that at this consumption rate, the oil reserves will have diminished within 47 years(https://www.worldometers.info/oil/). There needs to be a rapid change in the way we work as a society, starting from the simplest of things, such as reducing plastic waste, recycling and so on.

Take a look on Worldometers, again, there are statistics of how much coal, natural gas, oil there's left, while how much of the energy used today is coming from renewable and non-renewable sources.

https://www.worldometers.info/energy/

Calculating the oil reserves can be a challenging task. Because most of the petroleum deposits that are trapped in remote regions such as Arctic and deep-offshore are not included in the calculation right now. That makes sense, because extracting these deposits is not financially viable. But as technology progresses, it may become possible to extract these deposits at market-rate. Also, in a lot of countries gasoline is being replaced with LPG or CNG. That will reduce the consumption of crude oil and make sure that these deposits last longer.
You do have a point, however, we cannot actually predict when and if this is going to happen. There's certainly more petroleum and natural gas (CNG) sources, which we may not acknowledge yet. Despite that, there's a certain need to decrease our dependency on fossil fuels for energy, if you have a quick look on each country, through the sources I provided, the average energy produced from renewable sources is approximately 10-15%

You may calculate exactly how much we have, or may not and fail doing that but the fact is that there is a finite amount of it and we all know it. Sure most of it is still underground and it will take decades before we run out of petrol, but that doesn't change the fact that no matter what we do, eventually there will be no more oil.

Look at Saudi Arabia, they are buying so many things outside of their nation because they know that one day they will not be able to make profit from just oil and that is why they are trying their best to make as much investment into other stuff as they can. This will allow them to make profit even after all of the oil is over. What we should do however is stop it right away and start investing into renewable energy because we are ruining the whole planet by simply wanting a bit more profit for a few more decades, does it really worth it?

In the future, I think renewable energy will be used massively by all countries because given the current depletion of fossil energy sources and the use of fossil energy will also have a negative impact on the environment, therefore renewable energy is the right choice to reduce damage environment and prevent global warming.

It's definitely possible and you might say essential that the world eventually transitions to all renewable energy. Fossil fuels like oil are a finite resource as you say, eventually they will run out so we better have a replacement built up to take over or everything will grind to a halt. We are a very wasteful species and have killed off may thousands of different species as we slowly ruin the planet. Even if we do make the switch to renewables fast enough, hopefully we have avoided acidifying the oceans and there are still a diverse array of animal/insect life that is able to live in the inhospitable conditions that we have prepared. Unfortunately people bad estimators so weather conditions might get a lot worse and do a lot of damage in the near future.

What many people do not understand is that a fast transition is not going to be possible, there is too much money invested in the current technologies that we are using so it is going to take a lot of time before renewable sources of energy become the main source of energy around the world.

However as long as we can implement them and make a more efficient use of our energy then we are going to see improvements on the environment, and once enough time passes then a full transition will be possible, however I think this will take 4 to 5 decades at the soonest.

I agree with the first part, but not with the last. 5 decades is just too far. We don't have enough fossil fuels (including natural gas) to sustain us for that long. The big change needs to come in the next 10-15 years. Energy from renewable sources are getting cheaper with every passing year. I can give you an example. Solar electricity had a break-even price of around $0.40 per KWh just one decades ago. The same stands at $0.08 per KWh. And in the next 10-15 years, we can expect this to go down even further.
