In 1971, a husband and wife, Aden and Marjorie Meinel, patented an idea to produce solar panels in the Mojave Desert. The solar panels they proposed were to stretch through the Mojave Desert for 5,000 miles and would collect 1,000,000 megawatts of electrical power. The electrical energy would then be stored in a manufacturing facility locally so that the solar energy could be converted and used by millions of people. The Meinel’s proposal was dismissed in the 1970’s, but recently, solar panel plants have begun to sprout in the Mojave Desert. There are currently fourteen pending solar projects that have been proposed to be built in the Mojave Desert. There are also currently already four solar plants built there.…
The ideal system for homeowner is the grid connected system in which excess power can be produced than be sold back to the industry and reduces the immediate debt of the system, making it extremely convenient and satisfying for homeowners that are skeptical of investing in any of these solar-capturing devices, because of the potential for these devices to be effective and justifiable over time, however arranging for grid interconnection can be tedious and difficult. On the other hand with standalone systems, they are proven to be more cost efficient than power lines. However, with standalone, surplus power gained would be wasted or be preserved in a battery that the system runs on, following this further, standalone systems are also dependent on a battery source to operate during the night, and in standalone systems like the Hybrid we see the need for other and more additional sources of energy like wind or diesel, that ultimately defeat the purpose to the development and use of these solar capturing devices.…
The local council of Greenville recently made a proposal for all houses and businesses to install solar hot-water systems by 2010. Houses and businesses that who have not installed solar hot-water systems by then would be charged a “greenhouse levy”. However some residents have expressed anger over the proposal. “Solar Sellout” published in a local newspaper, an opinion piece and its accompanying cartoon written Bob Walsh, contends that the proposal which aims to reduce greenhouse gas emissions is not appropriate for the small suburb of Greenville. Walsh uses a sarcastic and angry tone which is quite personal, and aims to clearly outline why the proposal by the government is a bad idea.…
However, the disadvantages of solar energy were neglected in the early phase of development. It isn’t always as reliable as other forms of power and tends to be expensive to install and maintain, because the devices rely on a steady supply of sunlight to generate power. The equipment is not that efficient, typically converting just 10% to 18% of the sun’s energy into electricity [3]. On top of the price of panels themselves, the cost of installing them varies greatly by location and climate. By most estimates, it takes at least six years for the initial costs to be repaid in saving from power generation under the best circumstances, and double that time under less ideal conditions [3]. Besides, the batteries and safety serve as potential problems. Since it is impossible to generate solar power 24 hours a day, batteries are needed for most systems to store excess power for use at night and rainy days. Unfortunately, these batteries can be expensive and have a shorter lifespan than solar…
Despite what any individual’s concerns are regarding energy, it has been generally accepted that the finite source generating the majority of our electricity is depleting at alarming rates. We need to find alternative sources for energy production. The most obvious and abundant source available is the sun. Advances in technology have enabled us to harvest the solar radiation which has been conducting the cycle of life for millions of years. There are two main categories when it comes to solar power, passive and active. The passive solar systems integrate the sun’s energy to heat living spaces and/or water in a building. These system are very simple consisting few moving parts, require negligible maintenance and no mechanical components (Passive Solar Design). Passive…
Today nearly half of the world’s energy is provided by petroleum. What began as a cheap and abundant way to provide energy, has become expensive, environmentally harmful, and finite. With population explosions and the demands of modern lifestyles, the world’s need for energy production has become far too much for fossil fuels to keep up with. Experts say that the Earth’s stores of petroleum will be depleted by 2050. The need to find a viable source of energy within this generation’s lifetime that can power cars and provide electricity to homes. Some of the alternative energy sources include: wind energy, nuclear energy, and solar energy. Of the three, only solar is capable of producing enough energy to power the world. Solar energy producers fall into two separate categories: thermal solar collectors and photovoltaic panels. Thermal solar energy collectors are “a source of hot water that can be used for heating or for making steam to generate electricity” (Nersesian 2007). They are the simpler of the two types and much more inexpensive. They have many practical applications such as pool warmers and water heaters. Photovoltaic panels convert solar energy directly into electricity. They are large and the technology is still fairly expensive. Solar energy is a viable option to replace fossil fuels because it is the most financially viable long term, is a renewable resource that will not harm the environment, and each system can operate independently.…
Furthermore, renewable energy is a very niche market. It makes up only 8% of the total energy industry. SolarWorld’s practice, active solar technology, occupies just 1% of the total renewable energy due to its high cost and capital investment. This leaves a big hole for threat of substitutes such as coal, nuclear or natural gas energy, which are mostly the primary choice before renewable energy.…
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.…
As the population grows, so does the output of pollution grow to meet demands. Today, hearing how polluted/contaminated lakes, rivers, and other water systems remains just a common occurrence in the minds of the majority individuals. Even though this water persists in its contamination, millions upon millions of people still consume this water for drinking every day. Such occurrences can be shown with the Great Lakes, since 35 million people rely on the water for fresh water even though there have been reports of high levels of mercury and PCB (polychlorinated biphenyls which are industrial chemicals). A product definitely needs to be created that would be able to clean water sources of waste for the sake of local communities and the ecosystem.…
The assignment is based on solar energy and the title is “Solar Energy: and infinite resource meeting our infinite demand.” Firstly, solar energy is then introduced where it states that the energy radiated from sun is the solar energy which is essential for Earth. The aspects to be covered and the motivation for choosing solar energy are then explained. Pictures of solar cells are provided to have a better view of how solar power is generated.

When thinking of starting a contracting business for solar panels, many economic issues and concerns play a factor in the decision making process. Having a concern for the environment and knowing that solar panels have a cost saving for both households and business seems to be reason enough to start a business. However, before making such a financial investment you should first take a look solar panels in the economy in terms of (i) GDP growth rate, (ii) interest rates, (iii) level of unemployment, (iv) business cycle, (v) fiscal policy, (vi) monetary policy, (vii) international trade, and (viii) demographic.…
Water is a vital to all human life, but people don’t know how they should limit their use of it, how their actions affect the purity of it, or how restricted water actually is. They do not know how to take care of water, or their environment. They need to realize that water should not be carelessly used for leisure. Also, recognize that they pollute their own water supply with chemicals and trash, and they do not seem to understand that there is a limited supply of water.…
