...Sherrah Adderley Ms. Marjorie Downie Eng 300 October 16, 2012 Should the government invest in solar energy? The impact of high crude prices on the economy has always been negative, resulting in high energy cost. Many Bahamians continue to struggle to keep their lights on due to the constant increases in surcharge on electric bills by The Bahamas electricity Corporation (BEC) .To reduce this energy load, the government should invest in renewable energy such as solar energy. Solar power is one way we can explore renewable energy. Maybe Bahamians are reluctant to explore renewable energy because of perceived difficulty or cost. The government should invest in solar power because; it reduces cost, environmental safe and may create jobs.(smith) Solar energy reduces cost. Since solar energy is hundred percent free it means that it can reduce the energy loads such as lowering electricity bills by the use of solar panels, solar lights and other solar products. Solar panel is cost effective as it requires no maintenance. (Van) Once installed, there are no recurring costs involved and money can be saved in the long run. Solar lights are easy to install. This is because there are a few wiring issues and little need to ever dig supporting trenches. Many Bahamians argue that it is misleading to say that solar energy is free However, the price of solar energy is found in the expense of the technology and other factors involved in extracting it and transforming it into...

...Solar energy is simply the light and heat given off by the sun. most people actually want to know how we get power from solar energy. In other words, they really just want to know how we turn the sun’s heat and light energy into a usable power source. Both methods use solar panels to collect the solar energy but one process focuses on the sun’s heat and one process focuses on the sun’s light. The first process is called solar thermal which the energy works by harnessing the sun’s heat. The second process is the photovoltaic process Photovoltaic (PV) panels capture the light emitted by the sun and convert this energy into usable electricity. They do this by exciting the electrons in the solar energy which produces direct current (DC) electricity. DC electricity isn’t usable for most home needs. The DC electricity must go through a conversion process in a mechanical device known as an inverter. There many advantages of solar energy. The first one is Saving you money . After the initial investment has been recovered, the energy from the sun is practically FREE. It will save you money on your electricity bill if you have one at all. Solar energy does not require any fuel. The second one is Environmentally friendly. Solar Energy is clean, renewable (unlike gas, oil and coal) and sustainable, helping to protect our environment. It does not pollute our air by releasing carbon dioxide, nitrogen oxide, sulphur dioxide or mercury into the atmosphere like many traditional forms of electrical...

...ESL students. The science class was very enlightening and attention-grabbing to say the least because Mrs. Molosky had to differentiate instruction to meet the needs of the different levels. Every 2-3 weeks the teacher replaces one subject with the other depending on the depth of the information within the chapter and the rate at which the students grasp the material. At this time Mrs. Molosky was teaching a unit in Science called “The Solar System and Beyond”. During my observing of this unit of instruction, I was able to compile the information needed to respond to the questions within the module. The following is the information: Were other content areas such as reading, writing, math and technology integrated into the science lesson by the teacher? Yes, the teacher did integrate the content area of Reading by using compare and contrast, sequence, categorizing and classifying information, and drawing conclusions. The subject area of Math was applied through teaching how to calculate the distance in astronomical units in the Solar System. Astronomical units are the standard unit for distance...

...Rosario Carrillo HUM / 114 October 17, 2012 In Need of Alternative Sources of Energy There are many people that are debating how to best meet energy needs in the United States. The argument is that the country must decrease its dependence on oil and invest in alternative sources of energy. The United States uses oil daily witch tends to be very expensive. People believe that to best meet energy needs would be to find alternative sources, such as wind, and solar power. The truth is that alternative energy needs to become a major investment for everyone. The conservation of energy can result in the increased of financial capital, environmental quality, and comfort. The oil supply is decreasing daily and evenly that source will be extinct so why not start with alternative sources. Some argue that alternative sources are too expensive, but fail to realize that if he or she was to invest in an alternative source such as solar panels that they will acquire adequate lighting and a more healthful life. ”Solar incentives for homeowners reduce the energy cost by 30 to 50 percent” (Chiras, 2012, 5p. ). This is one of the reasons why it is important to invest in alternative sources of energy because the amounts of saving are so high. The price of electricity will increase witch will cause people to spend thousands of dollars on electricity because of the rising cost of oil. By encouraging more people to use alternative sources would help the United States to gradually clean...

...ADVANTEGES OF SOLAR ENERGY Solar energy is a renewable resource that is environmentally friendly. Unlike fossil fuels, solar energy is available just about everywhere on earth. And this source of energy is free, immune to rising energy prices. Solar energy can be used in many ways - to provide heat, lighting, mechanical power and electricity. Think about the money you’ll save once you are off the energy grid. SOLAR COLECTERS Active solar systems use solar collectors and additional electricity to power pumps or fans to distribute the sun's energy. The heart of a solar collector is a black absorber which converts the sun's energy into heat. The heat is then transferred to another location for immediate heating or for storage for use later. The heat is transferred by circulating water, antifreeze or sometimes air. Applications for active solar energy include heating swimming pools, domestic hot water use, ventilation and industrial process air and water for commercial facilities such as laundries, car washes and fitness centers. SOLAR ENERGY [pic] BY: CARSON COLE DOMESTIC HOT WATER Another common way to use the sun's heat is with the use of a solar domestic hot water system. Depending on how the system is used, a typical system will provide 50 to 75 per cent of a family's hot water needs. With water heating accounting for about 20 per cent of home energy use, a solar DHW system is an attractive method of reducing a home's fossil...

...Stardust is the NASA spacecraft that took samples of the Wild 2 comet. This craft returned samples that showed sampled of glycine, an amino acid used to make proteins. The mission took place in January of 2004 and the data was sent back to Earth in January 2006. These results were the first to prove that there are life ingredients in space. This proof restarts the issue of whether our species was created by a meteor or comet that came to Earth and left these similar samples. It’s perfectly logical to think believe if this one comet had these particles that many more could too. That they could be remnants of other planets or celestial bodies even. Dr. Carl Pilcher, Director of the NASA Astrobiology Institute which co-funded the research said, “The discovery of glycine in a comet supports the idea that the fundamental building blocks of life are prevalent in space, and strengthens the argument that life in the universe may be common rather than rare.” This is simply a hint of possibilities for what could be out there. Through this two-year journey much was accomplished. These accomplishments give scientists and astronomers even more of a reason to look into space in search for many things from life to more life ingredients. If our science today can accomplish something like this then the limitations are endless for future scientists and what they can find. Professor Donald E. Brownlee said it best when he said, “The discovery of amino acids in the returned comet sample...

...depletion of natural resources, so is interest growing in environmentally friendly products and services. For example, the popularity of green cleaning products has increased in recent years. Nontoxic, biodegradable cleaning products are safer for use in the home meaning they are less likely to cause health problems. They also keep harmful chemicals out of the environment. Compact fluorescent light bulbs (CFLs) are another popular eco-friendly product; compared to traditional, incandescent light bulbs, CFLs use way less electricity. Here are a four of the many types of green technology used today; green energy, vehicles, building and appliances. Green energy as of today is produced by these forms of energy; solar, wind, and hydroelectric power. Solar power or solar energy is a technology that converts the power of the sun into usable energy. It is a resource that cannot be used up by us using it. Much of the world's...

Power Supply 5v Solar - Circuit 2 5. Solar Charger - Push Pull circuit Some products are not yet available for 12v operation but inverters are available from 100watts to 4kw. The aim of this project is to cater for the other end of the range. We are looking at charging a 12v battery, using the cheapest set of solar cells and the cheapest inverter. This also means the cheapest 12v battery - a 1amphr (1AHr) gell cell or 6v cells salvaged from old analogue mobiles! THE PROBLEM The problem with charging a battery from a solar panel is the SUN! It doesn't shine all the time and clouds get in the way! Our eyes adjust to the variations in the strength of the sun but a solar panel behaves differently. As soon as the sun loses its intensity, the output from a solar panel drops enormously. No only does the output current fall, but the output voltage also decreases. Many of the solar panels drop to below the 13.6v needed to charge a 12v battery and as soon as this occurs, the charging current drops to ZERO. This means they become useless as soon as the brightness of the sun goes away. Our project cannot work miracles but it will convert voltages as low as 3.5v into 13.6v and keep delivering a current to the battery. Obviously the current will be much lower than the maximum, when the sun...

...Go to hyperlink http://phet.colorado.edu/en/simulation/my-solar-system and click on Run Now. 1. After the simulation loads click Start. Describe what you see in this simple sun-planet system. Specifically, what happens to the central object (the Sun)? Can you explain why the central object moves? HINT: Is gravitational attraction only the sun pulling on the planet? Does the planet orbit in a perfect circle? Is the sun at the center? Solution: Running the simulation we get the paths of the two body system as shown in the above figure. The central Object (The Sun) also moves along a closed path resembling a small ellipse. The motion of the central object must be attributed to the gravitational force acting on it by the smaller object causing smaller centripetal acceleration. No, the planet doesn’t move in a perfect circle. No, the sun is not at the center of a circular path. 2. Click Stop and then select 3 bodies. Then Start. Sketch a complete cycle (orbit). Watch the ‘funny’ object closely. What is it doing? Describe and explain. Could this be the Earth/Moon/Sun system? (Try un-checking Show Traces.) Is there anything you are uncomfortable with in the simulation? Explain. Can you explain the difference in the moon’s path when it is on the right side of the Sun compared to on the left side?

...Why I am a radical non environmentalist In my opinion, global warming is greatly over-exaggerated political issue that does not deserve the media attention that it receives. A plan to reduce consumption in order to prevent the overuse of resources is only effective if the entire global population agrees to abide by this. Global warming and sustainable development are strictly First World Country issues and seeing as the majority of the earth’s population does not fall within this category, my efforts to contribute to the decrease in climate change is obsolete. It is evident that change can only be established if every citizen in the world is willing to make an effort, and since this is not the case, I do not feel the need to participate. Though some may believe that every bit makes a difference, I am not one of these people. Aside from this, the issue of pollution contributing to global warming and climate change is blown out of proportion. I believe that pollution by big corporations is necessary to maintain our current standards of living. Also, without the existence of negative externalities, governments would not receive the extra funds used to support our universal health care system and our Canadian tax rates would increase further. A study done back in 2008 shows that the average temperature 1000 years ago was higher than it is now. Much of the predictions to climate change are from global climate computer models where in many scientist’s eyes are too crude to predict...
