2: SOLAR ENERGY | Solar energy is the sun’s rays (solar radiation) that reach the Earth. This energy can be converted into other forms of energy, such as heat and electricity.
3: Pros: -renewable and a never-ending source of energy - solar energy is not location specific unlike certain other forms of energy; anywhere that the sun is out, solar energy is available. -There is no question of any harmful byproducts whatsoever in case of solar energy. -financially beneficial and results shown in energy savings. | Cons: -The main disadvantage is the initial cost, solar panels are quite expensive due to the material cost and the complexity design to them. -Cloudy weather, rainy conditions, ect. -The days that there is no sun effects amount of energy produced. | In one hour more sunlight falls on the earth than what is used by the entire population in one year.
4: Wind | Turbines that look like big wind mills are generated by the wind, they collect the winds kinetic energy in the blades. The turbines transfer this energy to the power plants and from the plant the energy goes out to houses, stores ect.
5: -Owners have to scout out areas and see how good the wind is in that area to place a power plant. -A good place for a plant to put its turbines is on smooth rounded hills, open fields, and mountain gaps. -The top five states for wind energy are: Texas Iowa California Minnesota Washington There are also wind turbines off shore. (Horizontal axis turbines)- look like windmills (vertical wind turbines) - look like egg beaters. | People have been getting wind energy since early in history. Wind energy boats were along the Nile River early as 5000 B.C. By 200 B.C. Windmills in China were pumping water; vertical-axis windmills with woven reed sails were grinding grain in Persia and are Middle East. | Advantages: -It's a clean energy source. -It doesn't release any or few pollutants. -It also can slow down usage of fossils fuels for electricity. Disadvantages: -The turbines are really big and people don’t like that they are a visual impact. -Some birds and animals get killed by them because of their large size.
6: Advantages: -Safe -Clean -Very cheap -Efficient -One power plant can produce a lot of steam by drilling more than one well. | Disadvantages: -May cause small after shock earthquakes. -Minor damage may take 1000 years to recover. | GEOTHERMAL geo (earth) therine (heat) | geothermal energy sometimes finds its way to the surface in the form of: -Volcanoes -fumaroles (holes where -volcanic gases are released) -Hot springs -Geysers
7: Geothermal Geothermal energy is a renewable energy source because the heat is continuously produced inside the Earth. we get this energy by digging deep wells and pumping the heated underground water or steam to the surface. | The United States leads the world in electricity generation with geothermal power. Seven States have geothermal power plants: -California has 34 geothermal power plants, which produce almost 90% of U.S. geothermal electricity. -Nevada has 16 geothermal power plants. -Hawaii, Idaho, Montana, and Utah each have one geothermal plant
8: NUCLEAR POWER | Nuclear energy- The energy released by a fission or fusion reaction; the binding energy of the atomic nucleus. | Nuclear fission- The process by which the nucleus of a heavy atom splits into two or more fragments; the process releases neutrons and energy.
9: -During nuclear fission, a small particle called a neutron hits the uranium atom and splits it, releasing a great amount of energy as heat and radiation. | Pros: -Nuclear power generation does emit relatively low amounts of carbon dioxide. -The emissions of green house gases and therefore the contribution of nuclear power plants to global warming is relatively little. Cons: -Waste that is produced that can last up to several thousand years later. -Uranium is a scarce resource that will last only 30-60 years depending on the actual demand. | *Uranium fuel is formed into ceramic pellets. The pellets are about the size of your fingertip, but each one produces roughly the same amount of energy as 150 gallons of oil.*
10: HYDRO-ELECTRIC | -Hydro-Electricity is a renewable resource that is only used for about 20% of the time, which is when energy is produced from mobbing water.
11: -There are countries that are leading the world into the usage of Hydro-Electricity. ~Canada ~The United States ~Brazil ~China ~Russia ~Norway | Advantages: -It's simpler and cheaper to maintain a hydroelectric power plant than a nuclear power plant. -Hydroelectric plants last long and since the power generation processes mostly automated, less labor is needed to operate. | Disadvantages: -Hydroelectric energy plants, at times, can alter the local environment of an area to great extent. -Silt is a problem that adversely affects quite a few reservoirs, and consequently, the respective hydroelectric power plants as well. | The first hydroelectric power stationed in history started producing electricity in 1882. It was located in the state of Wisconsin and used the Fox River for electrical generation.
12: BIOMASS | -plant material, manure, and or any other organic matter that is used as an energy source. | Biomass is considered to be one of the key renewable resources of the future at moth small and large scale levels.
13: Cons: -some of the gases like carbon dioxide, methane, and nitrous oxide are emitted into the atmosphere during biomass production which may damage the ozone layer. | Pros: -Biomass helps in solid waste management by keeping us pollutant free. -incineration of biological waste everyday, cuts down the levels of expulsion of carbon into the atmosphere. | -The accumulation, harvesting and storage of raw biomass materials is quite expensive compared to that of fossil fuels. -the set up of the power plants requires huge space and the recycling of wast requires a large amount of water. | Biomass already supplies 14% of the world's primary energy consumption.
14: HYDROGEN | - The physical and chemical properties of itself that are what make it an ideal candidate for an energy source because of its vast amount of energy made within its chemical bonds. | Interesting Facts: 1.Hydrogen was used in airing balloons from the year 1783 until around the year that WWII began. 2.Hydrogen reacts extremely violently with Fluorine. 3.Many people in the 16th century thought that Hydrogen was a flammable gas.
15: Disadvantages: -Hydrogen is not a natural gas on earth. -It is not an energy source. -It takes a lot of energy to extract Hydrogen from water. | There are two very common forms that hydrogen can be extracted: -steam reforming -water electrolysis (water splitting). In these two processes hydrogen atoms are extracted from the water, the biomasses, and other natural gas molecules. | Advantages: -Hydrogen can be transported easily it has an advantage over electricity, because electricity cannot be easily transported. -Hydrogen can be used in many areas where electricity can’t be used in. (example in water). -Hydrogen is extremely light with a low density. -Using Hydrogen reduces pollution. -Hydrogen can be produced from many different sources. | The future of the usage of Hydrogen is that they will be used in cars. In the United States there is already about two thousand cars that are being powered by Hydrogen. Hydrogen energy is the cleanest fuel in the world that we know of today.
