Renewable energy

                   Define and provide a picture of each energy type.

1. Hydro Energy. Hydroelectric 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 of motion of energy

    2. Solar Energy. Energy derived from the sun's radiation. solar energy is used
          on  Earth in various ways. It is used as a passive source of energy, for                          example, in the form of sunlight that comes through a window and heats up a              room, or as an active source, as in the conversion of sunlight to electrical                    energy in solar cells.

    3. Wind Energy. Definition of wind energy. "The energy of wind converted                 into useful form (usually electric current) is called wind energy is                                   renewable energy source. Once used can be replaced. ... The rotational                         energy of the large wheel is also used in wind turbine which produced                           electrical energy.

     

      4.  Wave Energy wave energy (or wave power) is the transport and capture of               energy by ocean surface waves. The energy captured is then used for                           all different kinds of useful work, including electricity generation, water                         desalination, and pumping of water. 

1. Type: Hydro
2. Is it used in NZ? Yes
3. Other Countries that use it? Over more than 150 do.
   How is it used to 
   generate 
4. generate electricity? Hydropower 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.

1. Type: Solar
2. Is it used in NZ? Yes
3. Other Countries that use it? Other Countries that use it?Germany, Spain, Italy, Japan, the United States, and Czechia. 
4. How is it used to generate electricity? Solar-powered photovoltaic (PV) 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.

1. Type: Wind
2. Is it used in NZ? Yes
3. Other Countries that use it?  France, Canada, United Kingdom, Spain, Germany, The United States, and China.
4. How is it used to generate electricity? Wind power converts the kinetic energy in wind to generate electricity or mechanical power. ... As the wind passes the turbines it moves the blades, which spins the shaft.

1. Type: Wave 
2. Is it used in NZ? Yes
3. Other Countries that use it? Western coast of Scotland, northern Canada, southern Africa, Australia, and the Northwest Coast of the United States.
4. How is it used to generate electricity? Wave power converts the periodic up-and-down movement of the oceans waves into electricity by placing equipment on the surface of the oceans that captures the energy produced by the wave movement and converts this mechanical energy into electrical power.
