The Best Type Of Energy - 1400 Words

Around the world, there are hundreds of different methods of how to use alternative energy in order to save the earth from burning fossil fuels. Burning these, causes major air pollution and can be detrimental towards the health of thousands of populations. The best type of energy is photovoltaic energy because it possesses many advantages and it outshines the other alternative sources. In one day, the amount of sunlight shining over the United States is over 2,500 times the entire country’s daily energy usage combined. Photovoltaic energy is used to power solar panels by having particles of light, photons, free electrons from their atoms, thus generating electricity. Solar panels are composed of photovoltaic cells; these cells turn sunlight into electricity. Each cell is made up of two pieces of semi-conducting material, typically silicon, which is used to establish an electric field. This field occurs when opposite charges are separated and this is done by giving each piece a positive or negative electrical charge. When the photon pushes an electron free, the electron field will thrust the electron out of the junction between the two charged layers of material. This basic physical process, ejecting electrons in response to light, is known as the photoelectric effect. When this happens, the energy from the photon is shifted towards an electron that is in a photovoltaic cell. Metal conductive plates can then use these electrons as usable energy by collecting andShow MoreRelatedSolar Energy Is The Best Type Of Energy1651 Words   |  7 PagesWhen you close your eyes and think of solar energy, what do you see? Your response is most likely something positive such as an innovative, efficient, and renewable step forward into the future. Solar is also thought of to be the best type of energy because the sun will never go away. Well, solar energy will have to battle it out with natural gas and oil in the near future. â€Å"As the price of oil and natural gas continues to drop, solar energy looks less desirable as other sources become more affordableRead MoreSustainability And Construction Practices : Department Of Civil Engineering1256 Words   |  6 Pagesof renewable energy 3 Types of renewable energy i.

About 12.5 million children and teens, and over one-third of adults in the US have an obesity problem. The obesity problem in children and teens has nearly tripled in the last 30 years. Eating healthy foods can benefit a person by giving a person more natural energy, helping one maintain a healthy weight, and helping one live longer.

This form of treatment has many components that contribute toward ensuring the malignant tissue within the body is being adequately treated. One of the major components in radiation therapy is the use of bolus. Bolus is a material placed on the skin to help bring the radiation dose higher to the skin surface within the patient (Khan 2012). Since there are no research studies in the radiation oncologyRead MoreSolar Energy : Solar Power Systems For Houses And How The Humans Benefited From It983 Words   |  4 Pagesdiscuss solar energy in three points which are what solar energy is, solar power systems for houses and how the humans benefited from it. Solar energy is the light and heat which are coming from the sun, and a human create them for his benefits since ancient time ago. Also, solar energy is the important kind of green energy. Moreover, humans have used them by using a range of modern technology that is constantly evolving. It includes harnessing solar energy technologies using thermal energy of the sunRead MoreMaterials Engineering Of Photovoltaic Cells1696 Words   |  7 Pages In today’s world when we think about energy sources, there are 2 classifications they can be split into: renewable and non-renewable sources of energy. Fossil fuels are the backbone for most of the energy we use today. We need this fuel for almost all of our daily routine, from lighting a fire to running heavy machinery, but with increase in population there has been an increasing demand of such energy. Fuels like these tend to give massive amount of energy but also affect the environment by producingRead MoreGreen Computing Essay1118 Words   |  5 PagesGreen Computing is basically trying to save energy by reducing electricity and environmental waste. I can apply this to how I use my computing practices by listing ways that I can lessen my power usage at home doing my schooling and for people at work. With this I will acknowledge how often I use a printer to print documents as such. I will also express whether or not these gadgets have power savers or have hibernating mode that it goes in to save energy.
