I think considering the terrible economy we live in right now for the poor people, we could assume that world would be even more expensive if governments decided to spend more on it.

This is precisely the predicament the climate change alarmists insist we all suffer through. We all must pay elevated prices for our energy, and poorer countries who rely on cheap energy to survive must be subsidized by richer countries.

Of course, the argument they make doesn't make any sense.

When they're living in a rich country, it's easy to hold their sanctimony to a higher regard than someone living in Africa who might be using dung as a fuel source for mere survival.

I think with technology advancements, evolution and worldwide adoptions of renewable energy it could be possible to be a 100% dependent on it. The question is how long can we adopt renewable energy on our daily lives? Isn't it more expensive to maintain than the grid we are using today most especially in third world countries? Is it able to compete with the fossil fuel industry where we are at to this day? Is the source of this renewable energy sustainable to the entire demand of a country? Here in my country, there were foreign companies that introduces this renewable energy in the form of a solar farm, hydro, geothermal and wind energy both local and foreign companies involved and yet we are still using power grid.
Before getting to the question of how long we can apply renewable energy in our daily lives, I think it would be better to review whether we already understand what renewable energy is because basically things like this even though there has been a lot of news about renewable energy but in reality there are still many people who don't even know and don't really understand what renewable energy is.
This lack of understanding also makes most people confused so I think even though it will definitely be difficult but at least if the country wants renewable energy to be well adopted then it would be great if in the end there is further information for socialization because most people are still unfamiliar with renewable energy.

So I read a thread on the forum by Ultegra134 that talked about renewable energy and he asked;

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

The thing is, according to several studies and experts, it is possible for the world to be 100% dependent on renewable energy sources such as solar, wind, hydro, geothermal, and biomass. However, this would require a major transition of the current energy system, which is mostly based on fossil fuels that are non-renewable and contribute to climate change.

Some of the challenges and barriers to achieving this goal are technical, economic, social, and political. For example, renewable energy sources are often variable and intermittent, meaning they depend on natural conditions that are not always predictable or stable. This requires a reliable and flexible grid system that can balance supply and demand, as well as storage technologies that can store excess energy for later use.

Another challenge is the cost of renewable energy technologies and infrastructure, which may be higher than fossil fuels in some cases. However, many studies have shown that the benefits of renewable energy outweigh the costs in the long term, as they reduce greenhouse gas emissions, air pollution, health impacts, and dependence on imported fuels. Moreover, renewable energy can create more jobs and stimulate economic growth.

A third challenge is the social and political acceptance of renewable energy, which may face resistance from some groups or individuals who have vested interests in the fossil fuel industry or who are skeptical about climate change. To overcome this barrier, public awareness and education campaigns are needed to inform people about the benefits and feasibility of renewable energy, as well as policies and incentives that support its development and deployment.

In conclusion, it is possible for the world to be 100% dependent on renewable energy, but it would require a significant transformation of the current energy system and a collective effort from all stakeholders. Some countries and regions have already achieved or are close to achieving this goal, such as Iceland, Brazil, New Zealand’s South Island, Denmark’s Samsø island, and Germany’s Mecklenburg-Vorpommern and Schleswig-Holstein regions. These examples show that 100% renewable energy is not only feasible but also desirable for a sustainable future.


There's a lot of arguments to be made here, but there are fathoms:
1. The world has come to realize that limited natural resources are an evil to be avoided. In addition to problems for the economy, it can be an instrument of economic pressure or even terrorism (2022 showed this well).
2. Infrastructure for power generation and delivery is easier than oil/gas pipelines
3. fossil resources are not infinite, and according to many estimates, the reserves for today's consumption will last for 30-50 years. Therefore, there are no options - only transition to alternative variants

In conclusion, it is possible for the world to be 100% dependent on renewable energy.

In my opinion, the world is already 100% dependent on renewable energy; this is why we find developing countries and also developed countries doing their best to increase their production for Renewable energy sources.

Is it costly, yes (not as costly as non renewable energy)
is it the best, yes
 
So i think the question should be rephrased as, is it possible for the world to fine tune a non renewable energy source cheaply compared to renewable energy?

when a good idea appears, there are opposing ideas that appear too.  Now, just look at the automotive world which is being directed towards using battery energy, but there are still many people who refuse because it is inefficient and also expensive to maintain, the same goes for green energy, since ancient times we already know about solar panels, wind/water mills and geothermal energy, but why are there still many countries that use coal and oil to produce electrical energy?  from here we know that the government itself is not making the adoption of renewable energy happen.

i 100% support that renewable energy can be mass adopted throughout the world, but i don't know about others, it takes a hard struggle to direct human habits from using fossil energy to renewable energy.
Everyone needs to go through stages, and nothing can be instant. High costs are attributed to the fact that the supporting infrastructure is still not widespread, and not all repair outlets can handle it. Monopolistic practices by companies still occur during the initial launch of an innovation.

If the ubiquity of batteries becomes a global reality, competition will intensify, resulting in lower prices. It's akin to wind turbines or solar panels, which are still relatively expensive and not yet more stable than existing power generators.

I believe that the day when non-renewable resources are depleted will usher in a massive energy revolution.

Transition to renewable energy would require a lot, and this is an understatement. Even without even considering if the powerful people would accept these changes. It is possible if there's only one leader on the planet by that time, and he lives up to 200 years. BUT let us say all countries agreed to transform the world to become renewable energy dependent, for sure there will be a model country, a small country that has cheap labor and materials more probably around Asia, then other countries will follow, and so on.

Would this be worth after all if we used non-renewable energy to transform into a renewable energy-dependent world? coz I think for sure that's going to be our only one option to build it.


It is very ideal to utilize renewable energy because unlike non-renewable energy sources, they have little to no negative impact on our environment. Thus, they are sustainable sources of energy which means they last over time. But realistically speaking, it would be hard and challenging to transition from non-renewable energy to a 100% use of renewable energy because it requires a lot of time and money. Not only that, it would also require to have stringent planning because it does not just involve one sector, but all of us.

But again, this is a major change for us, and I think everyone will not approve because most of the industries are being run by non-renewable energy and it might affect them. So, I think in order for this to be feasible, the first step we must take is to educate people about the use of renewable energy sources and how it can benefit us and our environment.

Renewable energy development is capital intensive and demands groundbreaking effort to actualize it' and only well advanced nations are capable of achieving the feat and sustaining it . If we're looking at hydropower and geothermal energy only a very few countries can afford it's development.
In reality, this is still the case because of the many countries in the world, only a few countries are able to develop renewable energy, which is the newest model that has never been used by many less developed countries. However, as long as renewable energy can provide more positive things for the environment and the country, I think several countries that are not yet developed and are making themselves more developed should also study this so that in the future they can also use renewable energy for themselves.

Quote
Even as that those other sources of renewable energy preferably wind, solar that are regarded as the most cost-effective energy yet there are some countries that can't afford developing it, particularly those countries of the south pole that are battling to maintain non-renewable energy
Each country's ability to develop something like renewable energy is different because it not only concerns natural resources, but also involves human resources and certain tools needed. So when renewable energy already exists in several developed countries now, other countries also need to see it as a very important thing so that in the future they can also use it as used by these developed countries. Because developments in good things need to be considered so that countries that are not yet developed are not always left behind in terms of renewable energy.
Just as you've clearly said it is a new model, a model that even some of the advance countries have not been able to accomplish while some are in the process. And as for the government's developing countries AFAIK it's a matter of priority if this is something they give priority in their scale of preference that's when a study can be taken into action towards the future. Because there are other developmental needs of the people and the little available resources can only be directly to those that their priority lies on given their best ability based on what they can offer as developing nations.

Yes, it's technically "possible" to switch to renewables entirely. The pertinent question is how much GDP growth and how much wealth a country is willing to give up in order to take on the burden of switching to renewable energy. The cost analysis is rather clear that renewables will not generate a positive ROI, they will not pay for themselves. The countries that switched to renewables that you've laid out are either misleading on what percentage of their energy comes from renewables (meaning they still have carbon based energy sources that they rely on and therefore aren't entirely CO2 emissions free) or they don't have a large energy demand to begin with.

Carbon based energy sources are cheap and efficient. Having India, China, and the U.S. switching entirely to renewables within the next 20-30 years is economic suicide. The U.S. is on track to lower their emissions more than India and China, but even they would need something like 50+ years to go zero emissions.

And at which point, I've been informed by the climate alarmists, it'll be too late and we'll all die from climate change so what difference would it make.
I think considering the terrible economy we live in right now for the poor people, we could assume that world would be even more expensive if governments decided to spend more on it.

In a dreamy world, we would not have corruption, and that money would go to education, health, renewable energy and more stuff that are great for us like that, but it's not. That money goes to oil and gas subsidies where politicians get bribes from, and not secretly neither, a congressman could be getting "donation" from shell or bp, and then vote on something that will help them and this is perfectly legal. No idea how that's still perfectly legal, should be banned, but it is. Which is why we are not going to get any good renewable energy anytime soon.

Well, you're not entirely wrong, but you're not entirely right either. Your argument skims the renewable energy discussion without getting into economics. You say "long-term benefits" outweigh costs, but have you considered discounted cash flows or capital opportunity cost?

Remember that money runs the world. Who will pay for the massive upfront investments needed to switch from fossil fuels to renewables? Taxpayers? Large-scale economic transformations are typically difficult for governments. Manufacturing decline in the rust belt caused economic displacement.

Your third challenge about social and political acceptance is laughable. Public awareness campaigns? Please. More than pretty advertising and hashtags may change a global economy. Economic incentives speak louder than words. Market forces, not public opinion, will drive renewables. A harsh but simple fact.  Huh Huh

"The big question here is, can the world be 100% dependent on renewable energy sources? How can that be achieved and are they sustainable?"
It is possible and it is definitely sustainable, in more detail you can understand a little about renewable energy.

Quote
Renewable energy is an energy source that is available by nature and can be utilized continuously. This is in line with the statement from the International Energy Agency (IEA) which also states that renewable energy is energy that comes from natural processes that is continuously replenished.

The term "renewable energy" was born as a solution to the potential limitations of non-renewable energy sources that are widely used today.

Now you can find out the negative impacts caused by fossil energy throughout the world, such as: greenhouse gases which produce CO2, SO2 gas and NO2 and so on which can have a lasting impact on human life, whether economically, health and so on.

If renewable energy is used, it will certainly be beneficial for the continuity of human life, such as utilizing natural resources such as water, wind, sun, air and so on, all of which will have a positive and environmentally friendly impact, which have negative impacts caused by pollution and exploration, there are many benefits that arise from using renewable energy rather than non-renewable energy.

The use of renewable energy will have a positive impact on the economic session, by optimizing independent energy for the community, without having to depend and supply imported energy as now, This means that significantly, the presence of renewable energy will boost the economy of society as a whole due to its independence in using renewable energy without dependence on non-renewable energy.

I believe, at least in some places / countries can 100% depends on renewable energy. One of the biggest challenge is that renewable energy is very difficult to be distributed, compared to oil and coal which is very easy to be distributed. Sun can not be distributed, some places doesn't get enough sun at a certain time each year. Some places don't have enough geo thermal and water stream to depend on hydropower and both is very expensive on to be distributed.

Some countries and regions have already achieved or are close to achieving this goal, such as Iceland, Brazil, New Zealand’s South Island, Denmark’s Samsø island, and Germany’s Mecklenburg-Vorpommern and Schleswig-Holstein regions. These examples show that 100% renewable energy is not only feasible but also desirable for a sustainable future.

with the increasing effect of greenhouse gases in our atmosphere, making global warming increasingly uncontrollable, renewable energy is something that the earth really needs right now, but it is not easy to realize a world that uses 100% renewable energy, there are many factors that influence it; like politics, just imagine if the use of oil or coal is stopped then oil or coal entrepreneurs will no longer be able to make a profit, so they are as many as possible lobbying leaders in developing countries to continue to depend on oil and coal, Pollution in several big cities is also quite worrying. As recently happened in Jakarta, so far no one cares about the air in Jakarta, the residents are only busy with their own interests and the government doesn't care about that even though the carbon gas created by the daily activities of Jakarta residents is quite worrying.
You made a very strong point here when you mentioned about the politics that's involve when considering those countries hat economy depends on crude oil the "OPEC" countries the idea of renewable energy development despite how it sounds good for the climate against the effect of green house  gases on the global environment

to the oil producing countries it's a bad business for them and that's why the world at large will not be taken over by renewable energy even in the next 50 years because there's a strong politics underground from those OPEC countries.

As for atmospheric population generation from oil and coal I think same can be talked about with renewable energy like hydropower plants, where is the waste deposited and what are the health effect  is a question we have not asked ourselves.

here is the secret everyone in media does not say.

fossil fuel reserves will deplete before 2100 anyway.. in the 1980's the estimates were depletion by 2050..
this magic number is no coincidence.. the 1990's gulf war was waged due to the threat of fossil fuel reserve concerns.

we will have to transition to renewables even without a #climate tagline

the secret though is by making it a human survival threat it then makes people more empathetic that taxes should be used to fund private businesses transitions to renewables, whilst those same private companies can take profits from their charges they ask customers to pay.

so when you hear stories of "we need to stop using fossil fuel by 2050" its not to save the planet from smog. because we would naturally deplete fossil fuel by that same period anyway. instead its to reduce usage so that it can extend the longevity of fossil fuel reserves passed 2100, but at a usage rate of under 10% of the current usage to prolong the reserves.

im not saying fossil fuel does not cause climate change, but if we continue using fossil as we do now we will use it all up by 2050 anyway and the environment will heal itself afterwards all by itself

these funding programs for transitions to renewable is just to allow private businesses to continue making profit instead of using their income to self sustain their business by progressing themselves without tax grants

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

Yes it can take place but lengthy period of time is required for it and you also know that economic situations are not stable in any country therefore its not very easy to be depended completely on renewable energy.

In our country many people transformed from electricity towards solar energy because as compared to the electricity the solar system is quite lower in cost. Although plant requires huge money but after that there is no such amount needed to pay bills etc.

transformation of renewable energy can be possible but it will also harsh effects on humans as well as on climate of the world because if we are moving towards new technologies then there are some benefits at start but later we know that harmful effect of such technologies also there.

The biggest obstacle towards renewable energy is the Li-Ion batteries. They are used in both electric vehicles and in big batteries, which are used to store renewable energy when the solar panels and wind turbines are working at maximum capacity. Lithium is getting more and more expensive and Lithium mining extremely dirty(not to mention the protest of local people against the creation of new Lithium mines). This will create a Lithium shortage in the future and the price of Lithium will skyrocket. We need a cheaper replacement of Lithium for EV batteries and for big industrial batteries, which could store the electricity produced by solar and wind.
