Title: Solar Energy Definition Meta Tags: solar energy definition, solar panels definition, solar power definition, alternative energy, solar energy power Meta Description: Learn how solar panels harness the power of the sun to create a clean and renewable form of electricity that can save you money on energy costs. Simply stated, the definition of solar energy is energy that is created by the sun. In the context of modern usage, solar energy may refer to technology that converts radiation from the sun into usable energy sources, such as electricity. In essence, solar panels gather energy from the sun s rays and send the energy out through a process that results in electricity, that can be used to power homes, machinery and much more. Solar energy is a sought-after source of alternative energy because the sun offers a clean, renewable and cost-effective resource as long as it continues to burn and power life on Earth. Where It All Begins Solar energy from the sun begins with a fusion process called the PP, which is short for proton-proton, chain. The PP chain begins with gravity, as the core of the sun is extremely dense due to immense gravitational forces. The protons from hydrogen atoms in the core resist the force and create energy, which makes the temperature rise. The energized protons engage in violent collisions and eventually fuse to each other to create helium. Helium atoms begin to stabilize and release energy in the form of electromagnetic waves thatShow MoreRelatedEssay about Informative Speech Alternative Energy993 Words   |  4 PagesAlternative Energy Informative Speech Attention-Getter: Do you know what this is? This is worsening your asthma at the age of 10 and you developing lung cancer by the age of 30. According to the Centers for Disease Control there are 1 in 11 children with asthma (Centers, 2012a) and approximately 208,000 people diagnosed with lung cancer (Centers, 2012b). Fortunately, there is a better way. Credibility: I’m sure you’ve all heard about or seen windmills and solar panels. For those of you hereRead MoreThe Physics Of Solar Energy998 Words   |  4 PagesSolar energy dates back to 1839 with a French physicist by the name of Alexandre-Edmond Becquerel. His experiment of ‘illuminating two electrodes with different types of light† marked the birth of solar energy. Years later, William Grylls Adams, along with student assistant Richard Evans Day, discovered that converting solar energy into electrical energy is possible without the need of heat nor moving parts. Unfortunately, their panel couldn’t create enough power to run any electrical equipment.Read MoreA Report On A Hydro Electric Station936 Words   |  4 PagesIntroduction In recent days energy-sources are needed for electricity. An energy source is a structure which makes energy in a certain way, for instance a hydro-electric station. A hydro-electric station benefit the current of the river for the production of electricity. The importance of this report is that a better choice will be taken for a better electricity generation by a government agency. This report will compare between two electricity generation and they are Coal and Solar power which are bothRead MoreThe Basic Concepts Of Renewables2379 Words   |  10 PagesConcepts of Renewables Renewable energy’s definition is â€Å"Energy from a source that is not depleted when it is used† (â€Å"Renewable Energy – Definition†) and it is present throughout the world in a variety of countries. Given the variety of sources and the complexity of each, many other countries vie to stay with cheap, affordable, unhealthy non-renewable fuels such as natural gas, coal, and oil. This paper looks to review the production and consumption of energy – both renewable and non-renewable – overRead MoreAssess the Potential of Three Sources of Renewable Energy as Alternatives to Using Fossil Fuels in the Developing World1850 Words   |  8 Pagesthe main source of energy. However, faced with the notable increase demand for energy, fossil fuel, as a non-renewable resource becomes scarcer and more expensive nowadays. To solve this problem, the world needs to replace fossil fuels with other sources of energy which are relatively low-cost and more secu re. Renewable energy is such a potential energy. This essay will give an outline of three sources of renewable energy to be used in developing nations, which are solar energy, wind power and biomassRead MoreRenewable Energy : Fossil Fuels1808 Words   |  8 Pages Today, most of our energy comes from burning fossil-fuels such as coal and oil. There some inherent problems in basing the entire world s energy supply upon that kind of fuel, such as the fact that fossil-fuels are nonrenewable and will eventually run out. Burning fossil-fuels also produces copious amounts of pollution that is both harmful to the Earth and to humans. Although alternative forms of producing energy are not as efficient as nonrenewable methods, they are a lot more stable and reliableRead MoreAnalysis Of Renewables Or Bust And Its Effects On Our Health And Environment?1503 Words   |  7 PagesRenewables or Bust Many American cities have experienced the phenomenon of smog or haze at one point or another. This smog has led the general population, political leaders, and scientists to ask the question, â€Å"What produces this haze and what are the impacts on our health and environment?† (Fischetti). The average amount of energy consumed per person has dramatically increased over the past several hundred years (Christensen, 482). The prevalence of fossil fuel use in our world is a primaryRead MoreAlternative Energy : Renewable Energy966 Words   |  4 PagesAlternative Energy. What is it? Alternative energy: energy generated in ways that do not deplete natural resources or harm the environment, avoiding the use of fossil fuels and nuclear power (Google Definition). ALternative energy is the way to go: it is cleaner than Fossil Fuels and Nuclear Power, it works with the environment, and is benefitial to the community. First off, the majority of the world, 80% of the United States uses Nuclear power or Fossil Fuels as a source of energy and electricityRead MoreDuring the 21st century our country and our planet as a whole is in energy crisis.

Oil is limited and is at outrageous prices, this result is making our economy suffering. With fossil fuel and oil as the main source of energy the people of this planet need to start looking for an alternative energy source because our fossil fuel will not last forever and fossil fuel also polluted our planet. This is where a renewable energy comes in.
