Topic: Our future with renewable energy. - page 3. (Read 921 times)

If you remember the UK, then among European countries, I think that Germany will be a leader in this direction. But this is a long process and it is not so easy to immediately abandon nuclear energy, especially when it has always been the main source for many countries of the world.

Recently, we have increasingly seen how different countries are trying to use renewable energy sources, but this so far provides only a small part of the required capacity. China is now the leader in the production of solar batteries and they also use them, look, the length is about 80 kilometers, this is impressive.

Renewable energy is of course the right solution to replace natural materials such as oil and gas which are increasingly difficult, maybe at the moment this seems strange but slowly technology will emerge that can use renewable energy so that it is no longer dependent on mining products such as oil, gas and others. .

As compared to the pros the number of cons are more with that of renewable energy as we cannot get it easily and we cannot get benefit from it 24 hours per day. If we take an example of solar system so it cannot persist in every weather and every hour of a day.

The performance of renewable energy is not as fast as we requires but one benefit is here that world will not be effected by the harmful effects of sun when we use it to as a source of renewable energy. We will also be profitable and our money will be saved if we use renewable energy as it is cost effective and do not require much money to cover its bills.

The world is already moving towards renewable energy sources and having a lot of success with it, however it's an expensive business so it is the richest countries in the world who are leading the way most of the time. Just look at the UK, it has vast wind farms which have enabled it to generate it's entire eletrical grid energy needs for days at a time, purely off renewables. One thing that is key to it however is diversification and nuclear power should still be considered as a backup or baseline load option, because it is much more reliable. Improvements to battery and long term energy storage will also be essential, because at the moment it is hard to store energy so it needs to be used around the time it is generated.

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.

The point is that there are many obstacles to achieving the equitable application of renewable energy. And this has become a very normal thing. Because to achieve a change for the better definitely requires more effort. Which of course takes time because the research is quite long. Various things must be considered carefully. And again, there will always be pros and cons in world governments regarding this matter.

And building renewable energy infrastructure also requires quite large costs. So everything can only be done slowly.

Fortunately, all changes and advances in technology today are actually increasingly leading to renewable technology. In fact, investment in research in this field continues to increase. The goal is so that everyone can enjoy renewable energy but still at an affordable cost. But I doubt that will happen any time soon. But I believe it will happen. Even large companies like Tesla continue to research and develop technology that uses renewable energy. Or another example is the SunPower company which is currently famous as a solar panel manufacturer. And I believe there will be more and more companies operating in this field.

Another issue is that those technologies use rare-earth metals and China basically has a monopoly on those, and with the current political and economic climate they are already using them against western nations, now the governments behind those nations are trying to find a substitute for those elements and they are obtaining decent results, but who knows when they will be able to get rid of the Chinese influence on that field, which could delay the adoption of those technologies even further.

Using renewable energy has its pros and cons. Renewable energy is difficult to obtain in unsuitable weather conditions or from unsuitable materials. There is also the issue of durability. Often what is considered ideal is most often not. Therefore, the process of switching to renewable energy sources will be very long

In theory it can indeed be done. But the transition period from fossil energy to renewable energy is actually a big obstacle.

Apart from the fact that it requires quite high costs in making facilities and such. In fact, the real obstacle is that we ourselves may already be dependent on the use of oil fuel energy.

But if awareness of environmental sustainability is increased, I believe that in the future renewable energy will really be used and become the majority of usage. But building everyone's awareness is the most difficult.

High infrastructure and capital can be overcome. But human awareness to love nature more, I think this is the real obstacle.

Transforming the whole world into renewable energy is very difficult to implement.  For this, there will be many changes in our social system and life system which may be difficult to adapt to.  There are also many countries whose main trade is fossil fuels, they may not take the matter well.  Moreover, it is very complicated to maintain renewable energy. The industry of many countries of the world is immobile without fossil fuels.  In renewable energy we will not get the benefits that we are getting now.  Converting to 100% renewable energy is time consuming and difficult.

It's very possible for the world to move over to renewable energy. But there is large Market for crude oil already that is controlled by the high and mighty in the society, it has a very enviable profit margin. I feel this high and mighty people will fight the emergency of renewable energy because their source of wealth will be touched.
Secondly, it's too expensive to successfully establish the new structure of renewable energy across board, it can actually be done gradually with time but it will take a lengthy duration.

For me, making renewable energy come into fruition globally, it's something that should be done, because the direct emission of carbon has really affected and caused the depletion of the ozone layer,  there has been incessant occurrence of  heatwave is increasing by day, disaster like flood and wide fire constantly occurring. But if we begin to make renewable energy come through, some of this disasters will be reduced drastically.

Renewable energy for the world is much more efficient Renewable energy is a way to generate energy from unlimited natural resources. Different sources of fossil fuels such as natural gas, coal, mineral oil etc. are easily depleted as they are used up. On the other hand, renewable energy sources such as solar energy, wind energy, hydropower etc. do not get depleted easily with use and are renewable. Hydropower is the largest renewable energy source in the United States, with the total capacity of the Alta wind power plant and electricity in the United States and China. Renewable energy sources currently meet 26% of the world's electricity demand.
