Solar Energy
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 it." Every day solar energy is being used all around us. In fact, it is the indirect source of all energy and life on earth. Hopefully, with continued research, we will be in a place one day where we can directly rely on the sun for all our energy needs, and never have to use pollutive fossil fuels, or nuclear power ever again (Cross 124).
It is hard to say when solar energy was first used by humans to make life easier. As far as we know, people have always used the sun's visible range of light to see by, as well as to sit in the sun to keep warm. "Some of the first ancient cultures to use solar energy as heating were those from the deserts, and dry areas." In Egypt, Libya, and Algeria, where the sun is fiery hot in the day, but reaches freezing temperatures at night, builders discovered that thick walls of mud could solve this problem. During the day, they would absorb all the sun's energy and leave it cool as a cave inside, and at night, the walls would radiate their stored heat, and keep it fairly warm inside.
These ancient people also discovered how to use the sun's energy to preserve food by either drying fruits or meats in the sun, or baking them. They found techniques to bleach cloth and cure animal hides. Whether by accident, or deliberate experimentation, these ancient cultures discovered that the sun was an incredible source of power (Bower 36).
Throughout history people have experimented with the many uses of the sun's power. In the 17th century, scientists in Europe began rediscovering the sun. When a French scie...

...ar energy would be a more realistic option. Does every house need two computers, 3 TV's, a dishwasher, microwave, electric stove, video games, 3 stereos, nightlights in every hall, porch lights left on all night, lights on in every room in the house, blow dryers, toasters, electric heaters, air conditioners, electric gates and garage openers... the list goes on and on. One of the major problems that I see in our western culture is our obsession that we must each have our own. No one is willing to share anything, because it might be inconvenient. All we can think of is ourselves, no thought for future generations or the environment. We need to get a reality check. There is not enough materials or energy left in the world for this to continue to go on. Solar energy is a serious option that we should all be considering. We need to learn to act as a community, not only as individuals. I don't know what the future holds, but I can't see this working much longer. Change will have to occur soon, or we will exhaust all our resources and chances of life on earth.
the environment. Using Solar panels does not produce any carbon dioxide unlike fossil fuels that “produces huge volumes of carbon dioxide, which is a gas that influences the global climate” (“Solar Power Vs. Fossil Fuels”). Having the choice to get power in a new way that saves the environment, home owners should not have to think twice about trying solar. In fact if home owners collect some amount of watts per hour on Monday, that will not reduce the amount of solar energy a home owner can collect
History Of Solar Energy Table Of Contents: The Goal 2 Selection Of Sources 4 Application Of Information 5 Achieving The Goal 8 Reflection On Learning 9 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
that the energy demand will be increase another 50%. (Eco-Info) In 2009, it was estimated that within the next hundred years, all of the earth’s resources like coal, oil, and natural gas will be completely exhausted. (Eco-Info) Along with the depletion of these resources, many companies that harvest oil, natural gas, and coal are destroying the ecosystems and environments around them. People are slowly beginning to realize that there needs to be a change in the way we use and find energy. The solution:
Solar Energy is energy obtained by the sun. Solar Energy could be obtained by Solar Panels. Solar Energy would be most efficient here in El Paso because a lot of Solar Energy could be stored here since most of the time the sun is always here. Some of the most modern things in the market today are powered by Solar Energy. In El Paso Solar Energy would be best suited for the city. That way the people in El Paso know for a fact that the pollution in the country is not caused by the city. An advantage
Solar Energy ~Some history, types, and facts~ 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,
Solar energy is better for the environment than energy derived from other sources. Even though it is the most difficult source of energy to channel, solar energy can provide great amounts of resources for the environment as well as market venture, if proven effective. The fact that solar energy comes from the sun, makes it the most desired source of energy. Without solar energy, oxygen and food would be rare to find; mostly from the fact that the sun brings forth all life on planet Earth. The idea
environment. Solar energy is a suitable replacement of fossil fuel in term of green environment, recyclable, affordability and long lasting. Although, there are still many issues with solar energy which needs to be solved, but its availability far exceeds any conceivable future energy demands. A number of benefits could be gained from solar energy which includes dishes that concentrate the sun rays to heat fluid which drives engine and produce power. The installation of solar energy panel is very
Solar Energy Introduction: 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
Uses of Solar Energy Ever since the dawn of time, the sun has been a resource we cannot live or do without, so its not such a shock that man has come up with the idea of solar energy. Solar energy had many uses. Some can be dangerous and some, a very valuable asset to the modern world. Solar energy is energy derived from the sun in a form of ultra-violet rays. Its was first applied to use in 212 B.C., by the Greek genius Archimedes. Solar energy was used to defend the habor of Syracuse
Spend Less Dollars These days Using This Type Of Solar Power Suggestions There isn't any question that solar panel systems set up will help environmental surroundings. You should ascertain that solar technology is cost effective to suit your needs. When it suits you, the next report will allow you to see whether solar energy and. Your solar powered energy program will work appropriately in the event you preserve them. Doing the work oneself can save cash, even when you will save cash using this
Solar thermal energy is dead! A solar thermal heating system can cost upwards of $7,000 to install and it most likely won't even save you too much money. This is why many people debate over whether they should use a solar thermal water heating system, because they think they are saving money, or an inexpensive traditional water heating system. A traditional heating system is a system that is powered off of electricity, gas, oil or some other fuel. A solar thermal heating system uses the energy from
Solar Estimate Summary For the past few weeks, my classmates and I have been collecting data on the amount energy in kilowatts produced by solar panels on a given day. We have been guessing how many kilowatts of energy would be generated based on the forecast for each day, and then we were left with our estimates and the actual production of that day. In order to make this activity useful, we then took both numbers and found our percent error both weekly and daily. My best percent error days throughout
BrightSource Energy’s, a solar, green power producer located in California, has the capability to power over 140,000 homes (Wells, Chediak, and Goossens 1). Electricity is a huge part in today society; however, an increase in energy price has caused a spread of research for alternative methods to produce the necessity (Storey 47). Solar energy is one of the many safe, environment friendly alternatives to fossil fuels that are expanding today (Storey 48). Environmental safety is a key issue that needs
non renewable form energy is created by fossil fuels, such as coal, gas, and oil. The process begins at a power plant (primary energy source) where, heat exerted from burnin, are transformed into electrical energy. This creates high-pressured steam to form a turbine, which allows a rotor to power the generator. There an electrical current is created through the process of induction, by spinning an electrical current and conductor around each other. There the electrical energy or voltage is sent through
History of Solar Energy Even though most people think solar energy is a recent invention, it has been around for centuries, even in ancient times. Efforts to design and construct devices for supplying renewable energy began 100 years before the height of the Industrial Revolution. Engineers and scientists worried about what would happen to the world’s nations after using up the fuel supply. Most of the environmental visionaries realized that the potential rewards of solar power outweighed
