Power And Energy

  1. 1. Power And Energy By: Jenna, Cassandra And Denika
  2. 2. Wind Energy <ul><li>-Wind energy-Captures from wind turbines </li></ul><ul><li>Energy received from the movement of the wind across the earth. This energy is a result of the heating of our oceans, earth, and atmosphere by the sun. </li></ul><ul><li>Renewable </li></ul><ul><li>Stored: Wind turbines only produce electricity when the wind is blowing. So they are unsuitable to be the ONLY kind of electricity generation. They can store electricity in batteries while the wind is blowing, and this will be available in times of calm </li></ul>
  3. 3. Solar Energy <ul><li>-Solar energy-Capture by A Parabolic dish </li></ul><ul><li>Solar power is produced by collecting sunlight and converting it into electricity. This is done by using solar panels, which are large flat panels made up of many individual solar cells. It is most often used in remote locations, although it is becoming more popular in urban areas as well. </li></ul><ul><li>Renewable </li></ul><ul><li>Stored: If you’ve ever wondered how to store solar energy here are the basics. Solar energy is energy from the sun which is collected here on earth for heating, lighting and other human needs. Many of our basic energy needs can be addressed by using solar power. This can be done directly or indirectly but is not easy to do on a large scale. To store solar energy two components are required. </li></ul>
  4. 4. Fossil Fuels <ul><li>-Fossil Fuels- Capture By drilling </li></ul><ul><li>Fossil fuels are fuels containing carbon – coal, oil and gas – that were formed over millions of years through the decay, burial and compaction of rotting vegetation on land, and of marine organisms on the sea floor. </li></ul><ul><li>Non-Renewable </li></ul><ul><li>Stored: Put it in a gas container, coal in a metal can, oil in a oil container. </li></ul>
  5. 5. Hydroelectric Energy <ul><li>Hydroelectric-Capture by moving water </li></ul><ul><li>Generates electricity by converting the energy of moving water or relating to the electricity so produced </li></ul><ul><li>Dam: </li></ul><ul><li>A barrier constructed across a waterway to control the flow or raise the level of water </li></ul><ul><li>Renewable </li></ul><ul><li>Stored: 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. Hydroelectric power doesn't necessarily require a large dam. Some hydroelectric power plants just use a small canal to channel the river water through a turbine. </li></ul>
  6. 6. Biomass Energy <ul><li>Biomass-Capture by taking stored energy from plants and using it </li></ul><ul><li>Biomass is the common name for organic materials used as renewable energy sources such as; wood, crops, and waste. </li></ul><ul><li>Renewable </li></ul><ul><li>Store: you can store some biomass in your basement. Refrigerate </li></ul>
  7. 7. Geothermal Energy <ul><li>Geothermal-Capture by using energy from the earth </li></ul><ul><li>Pertaining to heat energy extracted from reservoirs in the earth's interior </li></ul><ul><li>Geothermal energy is power generated from natural steam, hot water, hot rocks, or lava in the Earth's crust. In general, geothermal power is produced by pumping water into cracks in the Earth's crust and then conveying the heated water or steam back to the surface so that its heat can be extracted through a heat exchanger, or its pressure can be used to drive turbines. </li></ul><ul><li>Non-Renewable </li></ul><ul><li>Stored: Geothermal Energy is stored inside the earth it will always be there and we can reach it there for later use. And that is how geothermal energy is stored and used for later use. </li></ul>
  8. 8. Nuclear Energy <ul><li>Nuclear energy is released by the splitting (fission) </li></ul><ul><li>Energy released by a nuclear reaction; either through nuclear fission or nuclear fusion such energy used as a power source </li></ul><ul><li>Fission: A cleaving, splitting, or breaking up into parts. </li></ul><ul><li>OR </li></ul><ul><li>merging together (fusion) </li></ul><ul><li>Fusion: The act or operation of melting or rendering fluid by heat; the act of melting together; as, the fusion of metals. </li></ul><ul><li>Non-Renewable </li></ul><ul><li>Stored: Nuclear energy appears as heat, and it is not practicable to store this heat, it has to be used to produce electricity. You could regard the new nuclear fuel as a store, the nuclear energy is there, just waiting to be released, and it would be practicable to stockpile fuel to be used if supplies of uranium were interrupted for some reason. I am not sure how much fuel is in fact stockpiled by the power companies that own power plants, but it would be possible for the federal government to pay to store more, if they wanted to. </li></ul>
