Can Renewable Energy Power The World – Posted on February 18, 2021 in the category: Can renewable energy power the world through renewable energy?
Renewable energy, also known as clean energy, comes from natural resources or processes that are constantly changing. Clean energy works by providing energy without having a negative impact on the environment, such as releasing greenhouse gases such as carbon dioxide. Renewable energy has long been used for transportation, heating, lighting and more.
If the world moves away from fossil fuels, will it be possible to generate enough energy to create a world with 100% renewable energy?
According to a report from LUT University in Finland, the answer is yes. The study concludes that the world is transitioning to 100% renewable energy by 2050 in all sectors. Research also emphasizes that renewable energy is better and more efficient than existing energy.
The world’s population is expected to increase to 9.7 billion in 2050, and total energy demand is projected to grow at around 2% per year to keep up with the high standard of living. To accommodate this growth, the study divided the world into nine major regions and 145 sub-regions. Energy consumption in these regions and regional areas is measured every hour in five years from 2015 to 2050.
Almost all electricity will be produced from a combination of existing and locally available renewable energy sources; The report says that decentralization of energy production will be essential for efficiency. In addition, the report stated that the transition of energy options to electricity and heat can be done by 2030, while the load will decrease by 2030 and 2050.
The report says that electricity supply in the renewable energy sector will be covered by the mix, with solar and wind power leading the way. Together they will make 88 percent of all electricity.
Clean energy is very important for the environment. Renewable resources conserve the world’s natural resources while reducing the risk of environmental damage, such as oil spills or problems related to carbon monoxide.

It is safe to say that we all know that we must find alternatives to fossil energy as soon as possible and that the best answer to the world’s energy needs is in sight for us every time we see it. The amount of solar energy that just 1 square mile of the earth in a year is equal to 4 million barrels of oil, and the energy that hits the earth in just 40 minutes can cover all the human energy needed for a year. Isn’t that amazing? Check out the infographic below to learn more about how solar is the way to go and how we can make it a reality around the world.

Today, it is very easy to get excited about solar energy. Panels are becoming cheaper as technology improves. Large-scale photovoltaic installations are popping up all over the world. Of course, solar power still only produces 1 percent of the world’s electricity, but it’s growing by double digits every year.
So with all this opportunity, you’d think the solar industry would sit back and celebrate, right? Rule is only a matter of time!
Two solar energy analysts, Varun Sivaram and Shayle Kann, say that solar energy still has economic problems to overcome before becoming the main source of energy and providing (say) a third of our potential. Meeting these challenges can mean the difference between solar becoming a technology and solar energy being used around the world.
Thanks to a little phenomenon called “depreciation,” the electricity produced by solar panels will decrease in value as more panels come online. The reason is that the number of solar panels must be increased very, very much, over time
How cheap is it? Sivaram and Kann say the industry should set a goal of pushing the cost of solar to $0.25 per watt by 2050 — down from about $3 per watt today. That’s a small number, and it may require thinking about solar invention in a whole new way. Current cost cutting will not necessarily get us there. We may need to try new technologies. Or new ways to integrate solar energy into our walls and windows. Or bot installers.
In an interview, the authors said that we are still several years away from deflation as a major problem. But that’s why it’s so scary to give up. If business doesn’t start creating long-term goals now, it can get stuck in “incremental [cost-cutting] strategies that lock us into the best solution,” said Sivaram, a Douglas Dillon fellow at the Council on Foreign Relations. .
So, let’s take a look at their arguments, which include different perspectives on the future of solar energy – some of them very exciting.
Sivaram and Kann’s review begins with the facts of solar panels: they generate electricity during the day, it rises at noon, when the sun is high in the sky.
This is now a feature, not a bug. Electricity consumption is usually higher in the evening, during the day, so installing more solar panels can help meet this demand. And because solar panels are inexpensive – once installed and paid for, they generate free energy – business owners use their electricity instead of “peaking” more expensive natural gas plants. It lost the overall price of electricity. Good news for customers!
The problem comes when you add more and more solar panels to a given grid. As it happens, the overall price of electricity falls when the sun shines. And every additional solar panel becomes less profitable in the market. 1
Technically, falling prices are a problem for all energy. If you add more gas plants to the network, the initial cost of each subsequent plant will decrease. But it’s a bigger problem for solar panels because they all generate electricity at the same time of day. Therefore, they eat their own business faster.
A 2015 MIT report, “The Future of Solar Power,” explains how these changes could play out in a competitive electricity market like Texas’s.2 As solar enters the grid, average payments decrease slightly (red line). But the income from solar power plants has decreased significantly (blue line):
This is “underpricing”, and it could be a big problem for solar energy as it becomes more important, potentially limiting access to it. Model studies in Texas and Germany show that when solar penetration goes from zero to 15 percent of the grid, the cost of solar energy drops by half. Research in California has shown a similar effect.
You can now use solar energy in this situation by providing additional subsidies or changing grid regulations to protect solar energy from falling wholesale prices. But that creates a new problem: price increases will make these policies more expensive over time. Dishes are not becoming more important because they are subsidized. (See here for more on this.) One way or another, price cuts must be addressed.
Note that many solar energy projects are not yet included in the overall competition. Most solar energy companies receive fixed income under long-term power purchase agreements (PPAs). And, according to metering laws, owners of rooftop solar panels often get a discount on the higher retail price for their electricity.
But in the long run, as solar power expands, these laws could change — many states already have metered laws — and solar owners will pay.
