Hurumanu - Renewable Energy | Solar powered oven





Aim: To make a solar-powered oven.

Materials: 
  1.   Sellotape
  2. Scissors
  3. Pizza box
  4. Straw
  5. Marshmallow
  6. Biscuit
  7. Glad wrap
  8. Tinfoil
  9. Black plastic
  10. Ruler
  11. Vivid marker
  12. Newspaper
Steps:
    1. Measure the box
    2. Cut the centre of the box
    3. Cover the bit you cut, with tin foil
    4. Put a piece of black plastic on the bottom of inside of the pizza on the bottom
    5. Make a paper square that fits inside the pizza box and lays around the edge
    6. Put a marshmallow on top of a chocolate biscuit, place  it on a plastic plate and put it in the solar oven
    7. Put it in the sun to cook

Conclusion





Aim: To make a presentation that investigates different renewable energy's.

Section 1: Title Page

Make a title page that incorporates all renewable energy 's Hydro, Solar, Wind and Wave.

Section 2: Definitions

Define and provide a picture of each energy type.
  1. Hydro EnergyHydroelectric energy is energy derived from the movement of water. Water has mass. It falls and flows downward due to gravity. When it moves, it has kinetic energy which can be harnessed. Kinetic energy is the energy of motion. Hydro or water energy is the conversion of hydropower into electricity. Hydropower refers to the force of water flow that turns turbines and powers generators, which then store the electricity into power grids for mass consumption. The hydropower process is a clean renewable energy resource because the water cycle occurs naturally. The movement of water throughout Earth’s systems is called the hydrologic cycle. This cycle is influenced by solar energy like other clean energy sources. This is because the amount of heat from the sun causes the water to change in the atmosphere, making it solid, liquid, or gas
  2. Solar Energy - Solar energy is created and used by harnessing the sun's heat and light. The sun is able to generate enough solar energy in one minute to supply Earth’s entire population with energy for a year. The energy is stored in what are called photovoltaic cells formed from semiconductor material. This type of mechanism is found in basic solar panels on people’s homes as well as on spacecraft and other machines in need of immediate energy. Photovoltaic cells produce energy when the Sun's heat hits the cells and cause electrons to be shaken free from their atoms. Another mechanism to harness solar energy is using the Sun's heat to boil water, which then generates electricity through steam-turning turbines.
  3. Wind Energy - Wind power or wind energy is the use of wind to provide the mechanical power through wind turbines to turn electric generators and traditionally to do other work, like milling or pumping. Wind power is sustainable and renewable energy and has a much smaller impact on the environment compared to burning fossil fuels. Electrical energy obtained from harnessing the wind with windmills or wind turbines.
  4. Wave Energy - Wave power is the capture of energy of wind waves to do useful work – for example, electricity generation, water desalination, or pumping water. A machine that exploits wave power is a wave energy converter(WEC).
    Wave power is distinct from tidal power, which captures the energy of the current caused by the gravitational pull of the Sun and Moon. Waves and tides are also distinct from ocean currents which are caused by other forces including breaking waves, wind, the Coriolis effect, cabbeling, and differences in temperature and salinity.

Section 3; Investigate each of the 4 Energy types.
( Hydro ,Solar ,Wind ,Wave ) 


  1. Type: Hydro 
  2. Is it used in NZ? Yes, New Zealand is using Hydro energy and New Zealand has been using it for over 100 years.
  3. Other Countries that use it? More than 150 countries produce some hydroelectricity, although around 50% of all hydro-power is produced by just four countries: China, Brazil, Canada and the United States.
  4. How is it used to generate electricity? 
  5. Draw and label a diagram of the main parts of the electricity generator? This can be done on paper and uploaded or on a drawing program on your device. I do not want any Internet images or pictures. They must be hand-drawn using a ruler and labelled.


Section 4: Renewable Energy in the future.

List 10 ways that renewable energy will be used in the future to replace our current activities.
