Future Of Renewable Energy In The World – Currently, our world gets most of its energy from coal, oil and gas. These fossil fuels are made from the remains of organisms over millions of years, and when they burn, they release heat energy that can be converted into electricity. However, they are dangerous for the environment, because the heat of the bones also releases a lot of carbon dioxide, which causes global warming.
When the sun’s energy hits the earth, about 70 percent of it is absorbed by the earth and oceans, and 30 percent is returned to space. However, 70 percent of what the Earth absorbs is returned to space in the form of infrared energy. Greenhouse gases then absorb this energy, but they also release heat in the process, which makes the world warmer and warmer. This process occurs naturally and is what keeps the Earth warm enough for life to survive.

However, the large increase in greenhouse gas emissions since the economic revolution has also led to an increase in the average global surface area. This also causes the world’s ice and ice shelves to melt faster, which causes sea levels to rise which causes flooding in small coastal areas. Global warming is causing more storms and hurricanes, and could lead to severe droughts in some parts of the world.
Scaling Renewables: The Converging World Of Oil & Gas And The Clean Energy Supermajors
Although fossil fuels are not this destructive, it will be important for us to find other sources of energy. Although fossil fuels are technically renewable, because they are produced by living things, the fact that we use them faster than they can produce them means that they will eventually run out.
Some renewable energy sources, such as solar, wind and electricity, are already in use, but these come with their own problems that prevent them from replacing fossil fuels. However, as we continue to find new ways to use unused energy, our world will soon become a green, self-driving machine.
Despite the limited availability of electricity from renewable sources, we are still dependent on fossil fuels. Unfortunately, there are still many hurdles to overcome before we can go all the way.
One of the main problems is the cost, as the necessary processes for most electronic products are expensive, especially compared to oil. Solar panels, wind turbines, hydroelectric dams, dams and nuclear fusion reactors are all expensive to build and store all the energy they produce.

Dependence on the weather can be another major problem for some types of renewable energy. For example, the wind is not the same, and in fact, the sun’s energy is collected mostly during the day. Therefore, fossil fuels are still needed to be stored when the weather is bad.
Currently, the technology used to collect renewable energy is not particularly efficient. Large areas of land or sea must be covered with solar panels or wind turbines to generate large amounts of electricity from non-renewable resources. This can lead to protests from local residents, as some believe that the wind has destroyed the countryside. Some renewable energy sources can have a negative impact on the local environment. For example, dams can disrupt water flows, disrupting wildlife and habitats, and dams can kill aquatic animals.
In fact, some fixed solutions are limited in some way. For example, geothermal energy is only produced near volcanoes, and geothermal energy requires a strong mountain.
Stars like our sun create a lot of energy using a process called fusion. When heat and pressure are encountered in the center of the star, hydrogen atoms are stripped from them to reveal their atoms. This soup of nuclei and electrons is called plasma, the fourth state of matter. When the plasma heats up, the hydrogen atoms move faster and collide, combining to form helium with more energy.

Because of the purity and efficiency of this process, scientists have now developed a way to change it around the world, with the hope that it will eventually eliminate the need for oil. In order to do this, they have built massive reactors, which use magnetic fields to generate temperatures of 150 million degrees Celsius (270 degrees Fahrenheit), which is ten times hotter than the sun. , and control the blood in the cylinder called. it’s a joke. The fuel used in the reactor is isotopes of hydrogen deuterium, which is produced from water and tritium, which is produced from lithium in the earth’s crust. The things we create now take billions of years, and just one kilogram (2.2 pounds) can provide the same energy as 10,000 tons of oil. In addition, the most important thing that creates fusion power is the small amount of helium, which does not cause bad weather.
Although the technology already exists to produce hybrid power, current hybrid controllers consume more energy than they produce. The challenge now is to build a reactor large enough to be a power plant, and the ITER project in France is the first step.
A Desalination plant uses energy and heat from the Sun to turn dirty or salty water into distilled water. It is self-sufficient and can provide a cheap, reliable and efficient source of water for cities and towns suffering from water shortages. Currently still in the development phase, the device can be used before the end of 2015.
Researchers at the University of Toronto have developed a new way to spray sunlight on a simple surface. Their SplayLD system uses colloidal quantum dots (CQD), nanometer-sized crystals that contain only a few thousand atoms, that capture sunlight and convert it into electricity. Then pour the liquid containing these CQD on a surface such as rubber, glass or food, in a single layer. After that, the chemical solution is sprayed on the surface, changing the CQDs from the electronic material to the electronic one, before the surface must be cleaned thoroughly. This process is repeated to create 65 to 85 rows.
Why Solar Is The Way Of The Future?
Until now, the only way to achieve this process is batch processing, requiring expensive and slow infrastructure. However, the SprayLD system currently in use is somewhat similar to newspaper printing. So while CQDs are half as efficient as conventional solar panels, they also cost less to make, meaning better value for money.
The ZEB Pilot House, designed by Norwegian architecture firm Snøhetta, uses sunlight and electricity to generate more energy than it needs. In fact, the excess energy it produces is enough to run an electric car all year round. The house, located in Larvik, Norway, is big enough to host a family.
The human body is a huge energy factory. Calories go in, like food, and then give energy to our body and muscles, causing more pain. The trip can generate 163 watts of electricity, but the biggest challenge is figuring out how to convert this into usable energy.
Scientists are exploring different ways to use human energy, and one way is piezoelectricity, which can be generated by the heart out of space through movement such as walking.

When the pressure is applied to substances that have atoms or molecules arranged in a good order, or crystal, the charge is discarded in proportion. The maximum gets a positive value when the others create a negative charge, and when the pressure reduces the flow of electricity between them, which can be stored and used as a source of electricity. Although this has been proven to work, it produces very little electricity, unfortunately not enough for most electric power.
Another way that has been explored to harness kinetic energy is through the use of magnetic materials. Researchers at the HSG-IMIT research center in Germany have developed a vacuum shock and rotating machine that can fit inside a shoe. When the heel hits the ground or the foot moves between the steps, the magnet in each hook moves the towel. This produces electricity, making the power as low as three to four. While it’s not enough to charge the phone, it can activate small sensors and transmitters that can track your movements, and the developers hope that it can be used to provide a device that is not used people
Anyone who has started exercising will know that exercise requires a lot of energy, but you may not know that it can give you strength. Some gyms, such as the Cadbury House Club in Bristol, UK, buy equipment that converts the user’s energy into electricity, using the machine itself and using too many seeds to open the gym. You can buy your own exercise equipment: PULSE jump rope
