The Goal
The topic of my personal project was the usefulness of solar energy over the period of humankind. I touched upon the basic uses of the Sun for our environment, and also the ways that us humans have been manipulating the Sun’s energy for reasons of luxury and survival. More specifically, how humans have taking advantage of and the Sun for heating, survival, and electrical use over the history of humankind.
I find that I am very attracted to the idea of renewable resources, and what us on Earth have been able to find out about the Sun over the course of history. Therefore, I determined that for my personal project, I would find a way to discuss and elaborate on not only how modern humans nowadays use the Sun for luxurious reasons, but also on a more simple scale, such as heating, survival, and the such. I also determined that the best way to show how far humankind has come with researching renewable resources was to go into history, and study how the history of the research have encouraged us to research further, leading to newer, more interesting discoveries throughout the years.
I decided to choose the Area Of Interaction of “Community & Service” for my Personal Project for many various reasons. Firstly, by choosing this Area Of Interaction, I believed that the best way to provide support to the community while giving them relevant information on my topic of solar energy was to make my own solar panel, record the steps I took to make the solar panel, and showcase it to the community...

...t I didn’t know about solar energy before this project, and that I knew only a sliver of what was out there to be learned before I made my pamphlet. I believe that this project has expanded my knowledge on not only solar energy, but also renewables as a whole.
I believe also that now, I can realize that our lack of non-renewable resources such as coal helped to also persuade me to want to go against non-renewables. I learned that by some statistics that the non-renewable resource that coal is will not exist on Earth / be able to be mined in less than a century; which was a surprising statistic that I put in my pamphlet in order to get the same reaction from the audience that I would be confronting.
From the research that I have done, I also realize that I’ve grown quite the interest into learning more about the other renewable resources out there like geothermal.

The Sun is one of the most valuable resources to us as human beings and we would not exist without it. It has provided the earth with energy since the beginning of the universe. One way that the power of the sun is utilized by us is through the use of fossil fuels. Fossil fuels are essentially energy stored by the sun from milllions of years ago. One of our most valuable fossil fuels is coal. We have been using it for decades, but are just now learning all of the negative drawbacks that come with burning coal. That is why many people are turning to Clean coal technology to continue to utilize coal for a power source.
Nowadays, over 5 million Americans are living with Alzheimer’s disease (Alzheimer’s Association, 2013). This statistic is staggering, and unless a prevention or cure is found, it’s predicted that 16 million of Americans will have Alzheimer’s disease by 2050 (Alzheimer’s Association, 2007). Alzheimer’s disease can be either sporadic or familial. Sporadic Alzheimer’s disease can affect adults at any age, but usually after age 65. Familial Alzheimer’s disease is a rare genetic condition where one of several genes is mutated and finally lead to Alzheimer’s disease, usually in their 40’s or 50’s. (Fight Alzheimer’s Save Australia, 2010) Alzheimer’s disease is the most common form of dementia. Alzheimer’s disease is an irreversible, (Sam Fazio, 2008), degenerative brain disease that slowly destroys brain cells, resulting in impairment of cognitive function and eventually even the ability to perform the simplest tasks of daily life.( Alzheimer’s Association, 2014) Unfortunately, Alzheimer’s disease has no current cure, but treatments for symptoms are available and research continues. For instance, Rivastigmine is a parasympathomimetic or cholinergic agent for the treatment of mild to moderate dementia of Alzheimer’s disease. The drug can be administered orally or via a transdermal patch and is normally sold under the trade name Exelon. (Wikipedia, 2014) ; (AMH,2013)
Preview: Today I will discuss the potential that solar power has to become this country’s main supply of energy and the latest research that can make solar power more efficient and cost effective. I will also present the environmental benefits that come with using solar power over other and more harmful forms of energy.
The lab activity that I will be writing an evaluation on is Solar Heating. There are several reasons that I chose this lab activity. First, I think students should understand that earth’s surface is unevenly heated by the sun. It is this uneven heating of the surface that creates wind, affects the weather, and makes the water cycle occur (Martin, Sexton, and Franklin, 2009). The materials that are needed are not excessive and are easily obtained. Finally, I think that this activity is simple to perform for younger middle schoolers. The directions are not too complex, so the students can focus more on their conclusions while not being overwhelmed with procedures.
Our Sun continuously converts hydrogen into helium and with this process it provides the essentials for life processes. In doing this it controls “our climate, provides light, raises tides, and drives the food chain” (Schaefer 34). Our Sun also has influenced many beliefs now and in the past. History has documented Sun worshipping religions while many current societies use solar calendars (Schaefer 34).
In chapter thirteen of our book, Environment by Raven and Berg, it shows us just how important renewable energy sources are. Currently the United States of America thrives on the use of fossil fuels and nuclear power. The main problems with these types of fuel are that they are both limited and can be extremely harmful to our environment. They cause global warming, air pollution, acid rain, and oil spills (Environment), and not only that, but in the grand scheme of things, these sources really aren’t even that cheap of a fuel source. There are many alternatives to these all but outdated fuel sources.
Our sun is the central pivot point to which or entire planet and solar system is built around. With out it all life on our planet would cease to exist. Within this paper we will explore how our Sun and solar system formed and came to resemble what we see today.
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.
When picking an energy resource for the topic of this paper, I bounced around a lot of ideas. Then it occurred to me that I should write about what I will be living with in about a month. My mom just finished designing and building our earthbag, solar, off-grid house, a four-year endeavor. I will soon live in a place powered by one of the most common alternative energy resources, solar energy, so I should learn more about it. At our new house, we have two stand alone pedestals with six 170W panels on each pedestal, making for a 2040W or 2kW solar system.
The year is 2200. The world is going through a fossil fuel shortage. Oil reserves are almost completely consumed and it is becoming impossible to find new fossil fuel sources. Not prepared for this event to occur, The United States, has no alternative options. As a result of the oil shortage, the standard of living deteriorates. Heat in homes, supermarkets full of food, and transportation, all basic necessities taken for granted, will be depleted because fossil fuels are used to power almost everything. The key to the prevention of this future is renewable energy. Unfortunately the support for the use of renewable energy is weak and ineffective. Unless the US puts forth effort to research and promote the use of renewable energy to consumers, conversion from fossil fuels to renewable energy will no longer be an option.
One of the most compelling arguments for the use of renewable energy is how many forms exist of it. Nuclear power, solar power, wind power, tidal power, hydroelectric power, pumped storage, wave power, geothermal power, biomass, and biogas are the most widely known renewable energy sources (Darvill, 2013). This large selection of fuels supports the idea of renewable fuels one day powering the entire planet. All the sources of energy have different niches and benefits. Solar energy is extremely ef...
The world that we live into today affords us the expectation that the flip a switch will turn the lights on. As populations increase and developing nations undergo dramatic economic growth, this energy demand will only continue to grow. The International Energy Agency (IEA) believes that “the world’s energy needs could be 50% higher in 2030 than they are today” (ElBaradei). Given this projected growth, it is necessary for world leaders must take action to secure the energy supply. Meaning that world leaders need to start seriously considering an alternative to non-renewable energy sources. “In 2012, the United States generated about 4,054 billion kilowatt-hours of electricity. About 68% of the electricity generated was from fossil fuel (coal, natural gas, and petroleum), with 37% attributed from coal” (U.S. Energy Information Administration). The fossil fuels that are used to supply over half of our country’s energy are in finite supply and are increasing in price to astronomical heights.
The Earth captures around 342 W/m2 of energy from the sun. This energy is in the form of solar radiation, which the atmosphere reflects about 77 W/m2 and will absorb around 68 W/m2 of solar radiation annually. Therefore, the Earth’s surface is receiving, on average, about 197 W/m2 of solar radiation annually. This amount of energy received is roughly more than 10,000 times the amount of all energy humans consume per year. This energy can be used to produce electricity or heat. This energy source is not being used to it’s potential considering how much effort would come into effect to store and transport this energy.
Using fossil fuels such as coal and oil is inefficient, dangerous, and otherwise a process that is known to eventually fail as a long lasting energy source. Yet, there is hope for the future of energy, this new hope has many shapes and forms, but requires a chance to be fully implemented in our everyday life. Such energy sources like solar energy, wind energy, geothermal energy, and hydro power are the key to our future. These energy sources are proven to be long lasting, safe, more reliable, and the next innovation. In short, all Americans should switch to renewable energy, resulting in a safer and more efficient world.
