Solar Energy is energy that has come from the sun. It can create either heat or electricity. Solar Energy is separated into two different categories Passive and Active. Passive energy is energy that has been turned into heat and Active energy, is energy that has been turned into electricity. Solar Energy is called intermittent source because it is not always available due to the sun being unpredictable. Even though it comes from the sun, which will never run out, if it is a rainy or cloudy day, the sun is not available to provide light. There are systems that have been built, that are designed with an energy storage feature, which therefore allows the user to continue to operate even when the sun is not shinning. As shown in image one solar power is a very simple process. When there is sunlight on the Photovoltaic Panels of a solar PV system, the sunlight is captured and converted into direct electricity. The number of PV systems that have been installed has increased of the last number of years due to the fact that it is a non-polluting clean energy source. The energy that a user will receive depends on the day. Insolatio...
Solar Energy What do the bubonic plague in the 14th century, the influenza epidemic of the early 20th century and the spread of HIV/AIDS in the late 20th and early 21st centuries have in common? One answer, according to Joel B. Stronberg author of the American Solar Energy Society’s “Common Sense,” is that they have all been called pandemics. According to Merriam-Webster.com, a pandemic occurs over a wide geographic distribution and affects “an exceptionally high proportion of the population.” Joel B. Stronberg declares that we are currently facing another pandemic. This pandemic is the combination of the consequences of burning fossil fuels.
The use of solar power to generate any type of energy is referred to as solar energy. Solar energy is very beneficial to both nature and humans. The use of solar energy actually helps against global warming (Shahan). Global warming is a serious issue that is worsening day by day and is
This paper will explore the many aspects of solar energy. From how it was discovered to what it is used for, how it is used, and the many benefits of it. Solar energy is defined as, radiant energy emitted by the sun. Solar energy has been used for many years and also has been used to generate a number of things that we use today, from solar powered cars and cell phones; solar energy is a huge aspect of human life as we know it. If it weren’t for solar energy, many things may not be able to operate and many other things may not have been discovered because of it.
... and monthly water filling. Solar energy is the cleanest and purest form of energy, allowing for cleaner air overall in our environment. There is great hope for a lot more solar panels to be installed worldwide. Solar is a viable alternative energy with solar panels becoming more affordable and more efficiently designed.
Nearly all energy in one form or another can be traced back to solar energy, and it is harness in many different ways. Solar cells are the most direct way to convert incident solar radiation into electricity, this process is also known as photovoltaics. Solar cells produce no pollution, noise, and do not contain any moving parts, allowing them to be tough, reliable, and long lasting. The natural light that we enjoy from the sun and see every day is only a fraction of the total energy emitted by the sun incident on the earth. The visible portion of sunlight is from just a small portion of the electromagnetic spectrum. 
Someday, our energy sources are going to run out. What will we do? What can we do? Our major source of energy now is fossil fuel. If that were to run out, there must be an alternate way to get energy. Because of this problem, there has been a lot of research going on. Through that research, alternate ways to get energy have been developed. They include wind energy, solar energy, nuclear energy, tidal energy and many more. In this paper I will focus on the aspects of solar energy. I will look at the history of solar energy, cover the advantages and disadvantages of solar energy and then finally I will talk about the concept of solar energy (how it works) and ways that solar energy can be used in your everyday life.
And even when the sun is up, the sunlight will be interrupted by occasional cloud covers, rainfall, fog and even smog. “So in order to harness the sun’s energy we need equipment that can get as much solar power as possible at a given time and we need some way of storing that energy so we can use without any interruptions.” Critics are flawed because every moment, enough solar energy hits the Earth to meet the world’s needs 10,000 times over. The best thing about it is you don’t have to pay for it, it’s just there, and humanity will be able to tap it for about the next 5 billion years. Solar energy promises to convert that free fuel to energy. Even better, this energy source come at a cost in generation of greenhouse gases. A solar array on your home is like installing a generator for which you never have to pay for fuel. Because there is no combustion involved in generating solar energy, it’s operation produces no pollutants. Solar power systems also have very low maintenance requirements, and typical warranties will cover a system for 25 years. And sunlight is abundant and ubiquitous, especially in warmer climates. “Because solar energy systems only produce energy during sunlight hours, you have three options if you want to rely on solar energy.” http://science.opposingviews.com/case-against-solar-energy-19638.html First, change people’s habits so they reduce their energy usage during evening and
The sun has been a major aspect of life since the beginning of time. People used many other forms of energy before electricity was discovered. There has been a debate over energy resources for years. Many people are worried about what current energy resources may be doing to the environment. Oil spills and nuclear power plant mishaps have only been a few accidents that have had a big impact on the environment and the people who inhabit it. There are plenty of energy sources that do not harm the environment and are still able to get the job done. Solar energy is one energy alternative that will insure the betterment of the country and, at the same time, protect the natural environment.
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 and healthy power? It is evident that solar energy is a healthy source of energy, which will help stop global warming all together, but it is economically efficient to switch everything to solar energy. Solar energy is capable of becoming the world's future power supply because, it is renewable, eco-friendly, and extremely efficient when strategically placed.
