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 two major problems from burning fossil fuels are global warming and decreasing oil

The potential of solar energy is tremendous. We should take advantage of this opportunity and make solar energy usage more common!
Since solar radiation produces so much energy, why aren’t we using a lot more of it? Solar energy does have some disadvantages. One of the major problems with solar energy is the intermittent speed at which it arrives at the Earth’s surface. This causes problems with consistency when heating or lighting. Another drawback to solar energy is that it requires great space to be gathered in effective quantities. This makes it difficult to place the solar panels in areas where space is costly, valuable, or unavailable. A final reason why we are not using solar energy is because it is quite costly. According to JC Solar Homes, it would cost a homeowner roughly one hundred to two hundred thousand dollars to convert his or her home to solar energy. Obviously, this is not realistic or reasonable for most people; therefore, solar energy is often overlooked as a serious possibility for solving our approaching energy pandemic.
There are different types of commonly used solar energy conversions. Photovoltaic energy is commonly called solar cell energy. PV is a non-mechanical device that converts sunlight into electricity. Solar thermal heat is being used in swimming pools, space heating and to heat water for domesticated uses. Solar thermal power plants use sunlight to heat a liquid which turns into steam. The
Solar energy is a resource that is not only sustainable for energy , It’s is indefinitely renewable. Solar panels also require little maintenance. The primary disadvantages of solar power is that it obviously cannot be created during the night. The power generated is also reduced during times of cloud
Haper Lee uses characters in To Kill a Mockingbird to explain issues that were plaguing the state of Alabama in the 1930’s. The character of Dolphus Raymond is used to explain the racism of America. Aunt Alexandra and Scout Finch are show in conjunction to outline the gender stereotypes woned faced and the Cunninghams are used to delineate the effect the Great Depression had on the south. Lee uses the character of Dolphus Raymond to demonstrate and explain the racism and prejudice that was running through southern states, like Alabama, in the 1930’s.
Fetal circulation is the pathway of blood circulation in the fetus (Anderson, 2002). The placenta has an amniotic filled sac attached to it called the amniotic sac. The placenta starts growing in the third week that a woman is pregnant. It starts functioning at four weeks of pregnancy. The normal growth and development of the fetus is the responsibility of an organ of pregnancy called the placenta. The umbilical cord secures the fetus to the placenta. Two arteries and one vein make up the umbilical cord. The placenta links the fetus to the uterine wall of the mother so that the mother and fetus can exchange nutrition and oxygen, as well as eliminating carbon dioxide and other waste products.
During the period from starting of the Collaborative Learning Community till date, there has been considerable progress related to the assignment. The preliminary work was directed towards the completion of the agreement and individual task assignment, which was completed successfully with mutual understanding. The next important part was to select a vendor, which was completed with some research and from the member’s experience with particular product.
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.
Renewable energy sources like solar, wind and hydroelectric are available but are not used often. I want us to put a limit on countries on how much non-renewable energy sources they can use. Only if we work together, help the other countries can we accomplish this. In fact, just today(1/24) Scotland has set a goal for using 50% renewable energy by 2030. I think that Scotland has set a realistic goal and that other countries should follow their lead. Non-renewable energy sources are bound to run out and when they do, we can either be ready by using renewable energy or have a global crisis. One of the best renewable energy sources currently is solar energy. Solar panels cost very little to install and have little to no maintenance. The sun provides us with more energy than we need. In fact, in just over an hour, the sun provides enough energy to run the world for an entire year. Even with the current 20% efficient solar panels, we could easily solve our energy problem. Therefore, by beginning to transition to solar energy today, we will be preventing a catastrophe of
In this modern fast paced world that we live in, there are many issues that are looked over, energy is one of these. As a world, we are dependant on dwindling fossil fuel supplies and take for granted electricity, oil, and gas. There are four completely renewable sources of energy around us that should be used and developed, they are: wind, growing plants, flowing water, and the sun. These sources of energy are the ones we should be tapping, because they are reliable and renewable. Harnessing the suns energy is the most certain and ultimate energy source. Looking at a brief history and some facts about solar energy, a glimpse of the future can be seen, a future not dependant on
Solar power is nothing completely new; it has been used for years to power small devices from calculators to watches, but what is new is its improved efficiency. Solar panels can be used to collect energy from the sun and now are being used on a much larger scale. Homeowners and business can use energy generated from the panels to power their homes and offices and have it purchased by energy suppliers. Solar power is proving to be an economical energy source available to the public that is consumer friendly.
Solar power harness the sun 's energy to create electricity. Solar energy assets are enormous and boundless, and they can be tackled anyplace that gets sunlight. The measure of solar radiation, otherwise called insolation, coming to the earth 's surface consistently is more than all the energy at present devoured by every single human activity yearly [1]. Various variables, including geographic area, time of day, and current climate conditions, all influence the measure of energy that can engage in for electricity creation or heating purposes.
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
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.
The creation of solar energy requires little maintenance and solar electricity power plants produce zero emissions. Solar power plants use two different types of technologies: Concentrated solar power and Photovoltaic systems. Concentrated solar power plants, also known as “concentrated solar thermal”, uses solar thermal energy to make steam that is converted into electricity by a turbine. A photovoltaic system, also known as solar panels, generates electricity from sunlight. It is a device that converts light energy into electrical energy.
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.
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
Solar energy is the most plentiful and purist renewable energy source available. Because it is completely natural, it is considered to be a clean energy source. It does not disrupt the environment or threaten the Eco-systems the way oil and some other energy sources tend to. Nor does it cause greenhouse gases, air or water pollution. Solar energy is an immensely important aspect of life and has been since the beginning of time. Increasingly, we are learning how to harness this important resource and use it to replace traditional energy sources. Modern technology can utilize this energy in a variety of ways, such as; generating electricity, providing light or a comfortable interior environment, and heating water for domestic, industrial, or commercial use. One day solar energy may well become our primary form of energy. This would lead to a clean environment, less money spent on utilities, and a healthier world. It is highly important because it has the potential to allow technology and nature to co-exist peacefully.
