Solar energy is the most ancient kind of energy found on earth, for it is as old as the sun. "Solar" means from the sun. The earth is only one of the many planets which is bathed in the sun's overflowing energy. Every second the world receives 95.8 trillion watts of power…just think about that for a minute. Think about how much power the earth just received in the time it took you to read this sentence? It is well beyond the amount of power used in one day. It has the potential to satisfy all our energy needs forever without ever having to use the pollutive fossil fuels ever again. "The problem however, does not lie in the limited source, as do fossil fuels, but in harnessing
On the other hand, the geomagnetic storms have been intensified and enhanced in their frequency as magnetic fields of coronal mass ejections indulges with that of the earth that causes change of direction and leave more radiation and magnetic energy into the environment of the planet earth. Solar Hemispheric Observatory and Solar
The foremost differentiation between solar flares and coronal mass ejections (CMEs) is the scale on which they transpire. Solar flares are rather little and local, occuring in the low solar atmosphere, near sunspots, where magnetic field lines are concentrated. CMEs on the other hand are huge. They can even be bigger than the sun itself!
The greatest energy that can be produced by the sun is electricity. Photovoltaics, or solar cells, capture the sun and convert it into electricity. Solar cells were discovered by the Europeans back in the 1870’s when they used selenium to develop the telegraph. They found that when light hits selenium it would produce and electrical current. Soon enough there were many scientists and engineers working on photovoltaic systems. Silicon and Selenium proved to be the two best elements to conduct electricity when light hits them. Photovoltaic systems (PV cell) work by converting the suns light into electricity. A semi conducting material absorbs the sunlight, that energy knocks electrons loose from their atoms, this allows the electrons to flow through the material to produce electricity. The further development of solar cells can be attributed to the satellite industry. Solar cells were expensive and there was no use for them until satellites came. Because it is impractical to tether satellites it became important to develop solar energy at any cost that would power these satellites. This created a sustainable market for solar power, the first of its kind.
This paper talks about the solar flares and how they go on to cause global warming. Global warming has been an ongoing phenomenon and there are many reasons it has occurred. Apart from the green house effect, global warming could have been due to the solar flares that have occurred. Different researches and theories regarding this matter are discussed in the paper.
Despite the amounts of incoming radiation, very little actually reaches the Earth’s surface. One layer of protection the Earth provides is in the form of a magnetic field that deflects charged particles from reaching the Earth’s surface. This magnetic field is generated by a combination of the liquids within the Earth’s core and the interplanetary magnetic field generated by the Sun. This field reaches out thousands of miles from Earth, so when solar wind travels through space and encounters Earth’s
The solar wind containing these hot gases races toward the edges of the solar system, and smash in to the magnetosphere. The magnetosphere protects the earth by deflecting most of the solar wind around the planet. Trillions of these charged particles mange to get through and project from the North and South poles. Energy released in this fashion excites atoms of nitrogen and oxygen, which in turn emit pulses of colored light. These formations are called an aurora. The aurora borealis, which are visible in Alaska, are a result of this sort of space storm.
I am certain that all have heard of the terms green house gases, fossil fuels, and global warming. Have you ever questioned what will happen if nothing is done about the environmental problems facing the world today? What if I answer you that, we can merely use the power from the sun to power up our entire planet without the use of harmful energy sources, which affect our atmosphere? The power from the sun is what we call solar power. Solar power is the energy that comes from the sun as light and heat energy, and then it is later converted into electrical energy through solar panels (Nelson, 2008). This kind of power is completely free, right? Why should we put a lot of expense on other sources of energy, when there is a complete free
In order for one to further understand the importance of solar energy, the problem of global warming must be explained. As defined by Webster’s Dictionary, “Global Warming” is an increase in the earth’s average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect. With an average increase in atmospheric temperatures, our planet is slowly deteriorating. In order to stall or halt this global destruction, countries must turn to solar energy as a cleaner alternative to the depletion of fossil fuels. Solar energy creates a homeostasis for the climate. Due to its ability to decrease global climate changes, solar power can address global warming in several ways.
Have you ever heard of a solar flare? A solar flare exists after a sunspot has existed for a long time and the magnetic lines of force usually become jumbled. As a result of this jumbling, magnetic energy is stored in the Corona (region of atmosphere above the chromosphere). The energy may be released in a spectacular discharge, which is a solar flare. A solar flare can be as wide as 367,000 miles and as high 500,000 miles out into space. A solar flare is nothing more than helium erupting from the sun like a volcano.
Solar energy and its use isn’t new to the world. It has been used by various societies beginning from 7thCentury B.C, when the sun’s heat was concentrated by glass and mirrors to light fires. Today, we have everything from solar-powered buildings to solar-powered vehicles. By and large solar technology has some environmental, economic, psychological and ethical implications for our society. Actions taken by companies and individuals to increase the use of solar technology will create good local jobs, improve our environment and reduce our dependence on foreign oil while doing what’s ethical and moral for our society.
Abstract: The current energy situation with fossil fuels as the main source of the world’s energy has two main flaws: fossil fuels contribute to global warming via the greenhouse effect and they are limited in the quantity that remains. Solar power solves both of these problems and can be captured by utilizing photovoltaic cells. However, photovoltaic cells have their own drawbacks due to their high costs of installation and maintenance.
