Why Solar Energy is the most promising renewable energy and how it’s harnessed

Solar Energy is the most promising renewable energy

All life on earth is supported by sunlight. This fantastic renewable energy resource radiates power and supplies us both light and heat by fusing hydrogen into helium in its center. We call it solar energy.

Only about half of the solar energy makes it to the planet’s surface. The rest is either absorbed or reflected by clouds and the atmosphere. However, we receive enough power from sunlight to meet the power demands of all mankind — millions of times over. Solar energy–electricity from sunlight –is a vast, inexhaustible, and clean source.


What is solar energy?

The solar power is what comes from electromagnetic radiation from sunlight. It is a kind of renewable energy because the Sun has been emitting solar power for 5 billion decades, and it is estimated that it hasn’t reached 50 percent of its existence.

Solar energy Is Clean and Secure

Solar is a secure alternative that may replace current fossil fuels such as coal and gas for the generation of power that creates water, air, and soil pollution. The World Wildlife Fund (WWF) notes that power production from fossil fuels causes pollution of the atmosphere resulting in acid rain, damaged forest regions, and influenced agricultural production resulting in a reduction of billions of dollars globally.

Fracking from the U.S. uses tens of thousands of gallons of water mixed with compounds for extraction contaminating the water utilized, together with neighboring water bodies, and causes earthquakes. Atomic energy pollutes water and land, and it has triggered environmental catastrophes. The use of solar power AKA Most promising renewable energy will remove these dangerous, unclean effects from using standard fossil fuels.

Solar Energy is best form of Renewable Energy

Types of solar energy

There are two chief kinds of solar energy

  • Photovoltaic (PV)
  • Concentrating solar power (CSP).

Most individuals are knowledgeable about PV as they have come across solar panels installation that they see increasingly about the top of buildings or even ones put on the International Space Station. After the Sun shines among these solar panels, then photons in the Sun are absorbed by the cells at the panel, which generates an electrical field across the layers and causes electricity to flow. They could be mounted in a permanent orientation to maximize value and production, or they might be mounted onto trackers that follow sunlight throughout the sky.

The next type is focusing on solar energy (also called targeted solar thermal and CSP). It’s used primarily in rather big power plants and isn’t suitable for residential usage. This technology utilizes mirrors to reflect and focus sunlight onto recipients that collect solar energy and convert it into heat. The heat is used to drive heating, normally a steam turbine connected to an electric power generator that’s later utilized to create power.

Converting Solar Energy in Electric Energy

How is solar energy obtained?

The Sun provides energy in two different manners:

  • It offers heat tapped by mirrors that focus sunlight onto a receiver, which contains a fluid which reaches temperatures around 1,000 ° C. The warmth transforms the liquid in the steam that moves a toaster and finally produces power.
  • It offers a light that is converted to electricity through photovoltaic solar panels. Photovoltaic panels have been formed by groups of cells or solar cells that convert light (photons) into electrical energy (electrons).

Pros:

  • Advantages of specific solar energy that it does not demand fossil raw materials because of its production, which avoids the removal of pollutants;
  • the Sun is an inexhaustible source of renewable energy, always being at our disposal. Despite requiring a large investment for its production, its use is cheap and saves energy.
  • Solar energy don’t create any waste, are easy to dismantle, and can even be recycled (95%); its national usage requires very little space;
  • In some countries, there are subsidies to utilize solar power, as well as the sale of excess energy or its accumulation; and its technology continues to grow, just like the development of transparent solar panels, which are already being tested in Japan, along with other solar panels inspired by nature.

 Cons:

On the other hand, as downsides of solar energy,

  • it’s convenient to say that solar panels have a visual impact on the environment,
  • the installation of solar plants is more expensive and require a huge space,
  • their functionality is somewhat low (between 18% and 40% . Based upon the kind ),
  • solar power is not necessarily the same; it depends on other variables (climate, latitude, etc..)

Do solar panels work in the winter?

Winters are undoubtedly the toughest time for solar power systems, but: solar panels certainly work during wintertime. When you simply take the right precautions, you can be certain your solar energy system will function properly, even during the harshest winter days.

During winters, the days are shorter, restricting the amount of electricity produced; sunlight strikes the panel at a lower angle leading to an additional reduction of the amount of available sunlight. Very often, the power demand is the highest through winters. This calls for the real test on your solar power system, and you’ll figure out when you sized your system properly.

What are the uses and benefits of solar power?

When we take into Consideration, Greenpeace estimates that photovoltaic solar energy Will Have the Ability to supply electricity to two-thirds of the Populace in 2030. The World Energy Council believes that by 2100 70 percent of the energy consumed will be of solar origin. It is necessary to review some of the most profitable uses of this renewable energy source:

  • Inexhaustible
  • Non-polluting
  • Avoids global warming
  • Reduces the use of fossil fuels
  • Reduces energy imports
  • Generates local wealth and jobs
  • Contributes to sustainable development
  • It is modular and very versatile, adaptable to different situations
  • Can be applied alike for large-scale electricity generation and on a small scale in areas isolated from the network

Solar energy the fast-growing renewable power source:

More than 486GW of installed capacity makes solar the third biggest renewable power source globally, with photovoltaic (PV) technology being dominant. The use of concentrating solar power (CSP) technology is also on the rise, with global CSP installed capacity reaching 5.5GW by the end of Last year.

China, the US, Germany, Japan, Italy, and India possess the biggest solar PV capacity in the world, while Spain has 42% of the global CSP capacity.

The annual growth rate of cumulative solar energy capacity has averaged 25% during the last five years, which makes solar the fastest growing renewable power source.

The solar industry is pushing forward, but markets and regulations need to keep up to enable the transition to a clean energy future. And Emissions Free World is on Mission to make the self-sustainable future backed by Renewable energy.
