Hurumanu: Renewable Energy

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

1. Hydro Energy - The Energy is generated through hydropower depends on the water cycle which is operated by the sun, this makes it a renewable power source making it a more reliable source other than fossil fuels that are quickly being wasted.

2. Solar Energy - Solar Energy is luminous light and heat from the sun that is harnessed using a reach of technologies such as solar heating & Solar Panels. It is a renewable resource, 

it is obtained from the sun's rays. Solar energy is transformed immediately to electricity through a solar photovoltaic panel. Solar rays are collected off reflective surfaces and heats an object to process it that creates solar thermal energy.

3. Wind Energy - Wind Power or Wind Energy is operated by the wind to provide it to function and make power through wind turbines to turn electric generators, it can 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.

4. Wave Energy - Wave power is generated by the up and down motion of floating devices placed on the surface of the ocean, Let's say that wind produces waves and waves produce energy, it is also renewable energy. As the waves travel across the ocean, very high-tech devices capture the physical movements of the ocean currents and the flow to generate power. 

This energy can be used to run turbines and there are plenty of places where the winds are strong enough to produce continuous wave movements or motions.

1. Type: Hydro
2. Is it used in NZ? Big hydropower systems have been built in the Central Plateau area of the North Island and in the Mackenzie Basin in the South Island, as a range of power stations on the Waikato River. Early designs such as the Waipori project selected in 1903 and the Lake Coleridge power station approved in 1914 organised New Zealand's use of renewable hydro energy. 
3. Other Countries that use it? A lot of countries use hydropower energy and it is the officiant way to get energy, countries like Nepal, Zambia, Paraguay, Albania and etc are using hydroelectric power.
4. How is it used to generate electricity? Hydropower capture's the energy of falling water to generate electricity. A turbine transforms the active energy of falling water into manufacturing energy, then a generator converts the energy from the turbine that is constantly spinning and turning it into electrical energy.

1. Draw and label a diagram of the main parts of the electricity generator?

Section 4: Renewable Energy in the future.

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

By using more renewable energy instead of fossil fuels, we would remarkably decrease the current levels of greenhouse gas release and this would have a positive impact on our environment for our entire planet. Renewable energy is not only all about the environment but also give a strong boost to our earnings in order of new jobs. I was told to list it but it is better if it was explained more into details.
