Hurumanu renewable energy

Aim: To make a presentation that investigates different renewable energy's.  
                                HYDRO
Hydro power is a clean, renewable and reliable energy source which converts kinetic energy from falling water into electricity, without consuming more water than is produced by nature. Quite simply the oldest method by which renewable energy has been harnessed by the human race.
                                   SOLAR 
The primary source of all energy on planet Earth is from the sun. Solar power is power generated directly from sunlight. Solar power can be used for heat energy converted into electric energy. When we use solar power, we don't use any of the Earth's resources like coal or oil. 
                                        WIND
Wind energy is clean and renewable. Large groups of wind turbines are called wind farms. Around 80 different countries use wind power to generate electricity commercially (as of 2009). In 1997 wind power generated only 0.1% of the world's electricity, this increased to 1.5% in 2008 and 2.5% in 2010.
                                                                  WAVE
Wave energy is the energy from wave motion. Waves are caused by the force of the wind "pushing" on the water surface. The stronger the wind, the bigger the waves. In bodies of water, such as the ocean, there are frequent waves.

Section 2: Definitions

Define and provide a picture of each energy type.

1. Hydro Energy
2. Solar Energy
3. Wind Energy 
4. Wave Energy

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

1. Type: wave energy                                                                                                                                                 
2. Is it used in NZ ? no but used to 3 years ago.                                                                                                                                                                                            
3. Other Countries that use it?  yes western coasts of Scotland, northern Canada, southern Africa, Australia, and the northwestern coast of the United States, particularly Alaska.                                                     
4. How is it used to generate electricity? Wave energy is produced when electricity generators are placed on the surface of the ocean. The energy provided is most often used in desalination plants, power plants and water pumps. Energy output is determined by wave height, wave speed, wavelength, and water density.                                                                                                           
5. Draw and label a diagram of the main parts of the electricity

7. 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.

Name: Solar
Is it used in NZ? Solar power in New Zealand is on the rise, but operates in an entirely free market with no form of subsidies or intervention from the New Zealand Government. As of January 2019, New Zealand has 90.1 MW of installed photo voltaic  solar power, of which 19 MW were installed in the preceding 12 months.

Other countries that use it?

• Germany. Germany is, without a doubt, the leading country for using solar energy. 
• Spain. Although Spain hasn't converted to solar energy to the extent that Germany has, it has been making an effort to use renewable energy more and more for several years. 
• Italy. 
• Japan. 
• United States. 
• Czech Republic.

How is it used to generate electricity?Solar-powered photo voltaic panels convert the sun's rays into electricity by exciting electrons in silicon cells using the photons of light from the sun. This electricity can then be used to supply renewable energy to your home or business

Name: Wind
Is it used in NZ?New Zealand's windswept landscape gives us one of the best wind resources in the world. Wind turbines don't produce greenhouse gas emissions as they generate electricity and are easy to remove, making wind power one of the most environmentally friendly forms of electricity generation.

Name: Hydro
Is it used in NZ?Hydroelectric power in New Zealand has been a part of the country's energy system for over 100 years and continues to provide more than half of the country's electricity needs. ... In 2014, hydro generation produced 24,094 gigawatt-hours 86,740 TJ
of electricity, representing 57% of the total electricity generated.

Other countries that use it?Brazil, Canada, New Zealand, Norway, Paraguay, Austria, Switzerland, Venezuela, and several other countries have a majority of the internal electric energy production from hydroelectric power. Paraguay produces 100% of its electricity from hydroelectric dams and exports 90% of its production to Brazil and to Argentina.

How is it used to generate electricity?Hydro power plants capture the energy of falling water to generate electricity. A turbine converts the kinetic energy of falling water into mechanical energy. Then a generator converts the mechanical energy from the turbine into electrical energy.
