Topic: Our future with renewable energy. - page 4. (Read 728 times)

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.

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.

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

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.

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.

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.

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.

"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 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.

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.

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.

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
