Types of Sustainable Energy

Types of Sustainable Energy Solar Energy Solar energy is consuming sunbeams it changed by using N-type and P-type semiconductor materials.   When the sunlight is captivated by these materials, the solar energy hits electrons loose from the atoms, allowing the electrons to flow into the material to produce electricity.   This method is called the photovoltaic effect.   Solar panels is the most popular way of converting light to energy with the use of ultraviolet and infrared light can be converted into reusable energy. There are a variety of technologies that have been developed to take advantage of solar energy, which include solar hot water heating hot water with solar energy, the use of solar to produce electricity and solar energy to heat and cool homes and office buildings. Geothermal Energy This energy is the warmth from the earth.   It has benefits as it is clean and sustainable.   Resources of geothermal energy range from the low ground to hot water and hot rocks found a few miles below the earths surface and down even deeper to the extremely high temperatures of molten rock called magma.   The shallow ground and or upper 10 feet of the earths surface maintain a nearly constant temp between 50 and 60 degrees F (10 to 16 centigrade).   Geothermal heat pumps can be tapped into to heat and cool buildings. Geothermal warmth pumps can tap into this resource to heat and cool buildings. A geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger-a system of pipes buried in the shallow ground near the building. In the winter, the heat pump removes heat from the heat exchanger and pumps it into the indoor air delivery system. In the summer, the process is reversed, and the heat pump moves heat from the indoor air into the heat exchanger. The heat removed from the indoor air during the summer can also be used to provide a free source of hot water. Hydroelectric Energy Flowing water creates energy that can be captured and turned into electricity. This is called hydroelectric power or hydropower. The most common type of hydroelectric power plant uses a dam on a river to store water in a reservoir. Water released from the reservoir flows through a turbine, spinning it, which in turn activates a generator to produce electricity. But hydroelectric power doesnt necessarily require a large dam. Some hydroelectric power plants just use a small canal to channel the river water through a turbine. Another type of hydroelectric power plant called a pumped storage plant can even store power. The power is sent from a power grid into the electric generators. The generators then spin the turbines backward, which causes the turbines to pump water from a river or lower reservoir to an upper reservoir, where the power is stored. To use the power, the water is released from the upper reservoir back down into the river or lower reservoir. This spins the turbines forward, activating the generators to produce electricity. A small or micro-hydroelectric power system can produce enough electricity for a home, farm, or ranch. Biomass Energy We have used biomass energy or bio energy, the energy from organic matter for thousands of years, ever since people started burning wood to cook food or to keep warm.   Today wood is still our largest biomass energy resource, but other types of resources can now be used this includes plants, residues from agriculture or forestry and the factors of industrial waste.   Even the fumes from landfills can be used as a biomass energy source. The use of this reusable energy can potentially reduce our greenhouse gas emissions and produces the same carbon monoxide as fossil fuels but every time a plant grows, carbon monoxide is removed from the atmosphere. Wind Energy Wind turbines, like windmills, are mounted on a tower to capture the most energy. At 100 feet (30 meters) or more aboveground, they can take advantage of the faster and less turbulent wind. Turbines catch the winds energy with their propeller-like blades. Usually, two or three blades are mounted on a shaft to form a rotor. A blade acts much like an airplane wing. When the wind blows, a pocket of low-pressure air forms on the downwind side of the blade. The low-pressure air pocket then pulls the blade toward it, causing the rotor to turn.   The force of the lift is much stronger than the winds force against the front side of the blade, which is called drag. The combination of lift and drag causes the rotor to spin like a propeller, and the turning shaft spins a generator to make electricity. Wind turbines can be used as stand-alone applications, or they can be connected to a utility power grid or even combined with a photovoltaic (solar cell) system. For utility-scale sources of wind energy, many wind turbines are usually built close together to form a wind plant. Several electricity providers today use wind plants to supply power to their customers.

What Lay Behind the Horrors of the Slave Trade

What Lay Behind The Horrors Of The Slave Trade? In this essay I would be examining what lay behind the horrors of the slave trade. This essay will include the countries that were involved in the slave trade, how they benefited from it and the power they had over the enslaved Africans. The slave trade worked in a triangle, between four continents: Europe, Africa, South America and North America.Slave ships leave ports like London, Bristol and Liverpool for West Africa carrying manufactured goods like guns, alcohol, iron bars, which are traded for African men, women and children who had been captured by slave traders or bought from African chiefs on the West African coast. From Africa a ship full of slaves leaves to America and the West Indies, where they are sold to the highest bidder and that’s where families are separated. Once they have been bought, after that they belonged to the plantation owner.Some refused to be enslaved and took their live, others run away and pregnant woman preferred to have an abortion than to raise their children into slavery. With the money made from the sale of enslaved Africans, goods such as sugar, coffee and tobacco were bought and taken back to Britain for sale. The ships were loaded with produce from the plantations for the voyage back home. For over 300 years, European countries forced Africans onto slave ships and transported them over the Atlantic Ocean but how did the people back in Britain get involved in the slave trade?As the slave trade grew, numerous of people began to get involved or simply benefited from it. Banks and finance houses in Britain began to grow from the fees and the interest they earned from merchants who borrowed money for their voyages. Bristol and Liverpool became major ports for slave ships, handling cargoes they brought back and between 1700 and 1800, Liverpool’s population dramatically rose from 5,000 to 78,000. Others worked in factories that had been set up with the money from the s lave trade.The slave trade also provided various jobs back in Britain, many worked in factories which sold their goods to West Africa, and these goods will then be traded for slaves. Birmingham also included itself by having 4,000 gun makers with 100,000 guns a year People in Britain weren’t the only one who benefited from the slave trade, West African leaders involved in the trade also benefited by capturing and trading Africans to the Europeans because they are the one who got all the manufactured goods that were traded for slaves. The African chiefs were also benefited themselves with all the money that they got from trading Africans.My view is that because of the benefits they had, it means that they were also involved and I think without them the trade wouldn’t of happened because they are the one who captured slave for the Europeans, therefore they made a path for the slave trade to happen. Lastly, the West Indies and the Americans were obviously involved because they are the ones who bought and owned the slaves for their plantations. Plantation owners who used slave labour to grow their crops and the fact that they didn’t have to pay the slave made them vast profits.Often planters retired to Britain with the profits they made and had grand country houses already built for them. Some planter used their money wisely, to become MPs and others invested their profits in new factories and inventions wish helped to finance the Industrial Revolution. I would like to conclude that for me the biggest horrors that lay behind the slave trade is how other African traded their own kind for manufactured goods, how cruelly the Africans were treated on the slave ships and plantations and the power that the Europeans , the Americans, and some other Africans had over the slaves.I also think that the slave trade was unnecessary, but all those four continents that were involved benefited from it one way or another as they all played important roles beca use without one, let say the West Indies and Americans, who would of bought all those slave? Or which plantations would the slaves have worked on? And the slave trade wouldn’t have been so successful or benefiting without one side of the triangle. Or without the slave we wouldn’t have what we have today but I still think the way they treated black people was out of order and shouldn’t had to happen in order for the countries to have wealth.

Relief Brought to the American People by Roosevelts New...

Having gone through severe unemployment, food shortages, and a seemingly remiss President Hoover, the American people were beginning to lose hope. But sentiments began to turn as FDR stepped into office and implemented his New Deal programs. FDR and his administration responded to the crisis by executing policies that would successfully address reform, relief, and, unsuccessfully, recovery. Although WWII ultimately recovered America from its depression, it was FDR’s response with the New Deal programs that stopped America’s economic downfall, relieved hundreds of Americans, reformed many policies, and consequently expanded government power. One of FDR’s first orders of business was to respond to the need of reforming the banking system.†¦show more content†¦Yet, it implanted hope into millions of Americans for the well-being of their future and the capitalist system. The Social Security Act was also revolutionary in changing the government’s role by showing how a citizen’s welfare was now also part of the government’s responsibility. All these new programs and organizations created by the New Deal show how they greatly expanded the government’s power and influence, as shown in Document C. In Document C, the cartoon shows how FDR’s New Deal was a progression of small change that consequently led to an expansion of government power. The New Deal’s many reform programs provided a foundation for America to build off of. FDR’s New Deal also sought out to provide relief for Americans. Unemployment rates were high and poverty was widespread. To solve these problems, FDR created many programs and organizations, such as the Federal Emergency Relief Administration (FERA), the Civil Works Administration (CWA), the Civilian Conservation Corps (CCC), and the Works Progress Administration (WPA). Document A shows how poor women, and also men, were barely assisted by the government. Urban unemployment represented a big problem in the US.
