Gas versus Wind as an Energy Source - Jayden

  1. 1. J A Y D E N
  2. 2. Wind energy (Non fossil and renewable) Gas energy (Fossil fuel and Non renewable) What is it? • Wind energy is a non fossil fuel • It is created with the wind turbines which are basically really large fans • It is a clean energy source • Gas fuel is a fossil fuel • Once it is used it can not be salvage for reuse Where do you find this energy source? • All wind energy in the world comes from wind turbines, there are over 225,000 turbines that are operating wide spread over 75 countries. • Natural gas is extracted from two different locations, way under the sea bed and also deep underground. Mortlake power plant collects its gas from a dedicated 83Km wide spread underground gas transmission pipeline
  3. 3. Wind energy (Non fossil and renewable) Gas energy (Fossil fuel and Non renewable) How does it work? • Air and gas mix together causing a combustion within the turbine • The force of the combustion causes the rotors in the turbine to spin • The turbine is then coupled into a generator • The turbine is then coupled to a generator • As the turbine spins, the generator rotates and produces electricity • Electricity from the generator is passed through a transformer and uploaded to the grid • Wind causes the blades to spin • This causes a shaft to spin and connected to the shaft there are a set of magnets and copper wire • When they start spinning on the shaft this causes the generator to react in the same way and when it starts to spin it generates electricity
  4. 4. Wind energy (Non fossil and renewable) Gas energy (Fossil fuel and Non renewable) Transportation • Connected to the Mortlake gas plant there is a dedicated 83 Km Underground natural gas transmission pipeline, most gas plants use this method because it is an easy and effective way of transferring the point of origin to the location with the highest gas energy demands when ever it is needed. • Wind energy can not be transported • Although wind energy it self can not be transported the parts had to be transported to the wind farm area, parts came from places such a Denmark just to get all the way to Macarthur.
  5. 5. Usage
  6. 6. Worldwide installed wind capacity
  7. 7. Wind energy (Non fossil and renewable) Gas energy (Fossil fuel and Non renewable) Why the location and How is it been affecting the land? • The land of the Mortlake gas comes to a total of 100 Hectares which is owned by origins, there is 20 Hectares which is used by the actual gas plant that consists of the facilities, roads for people to navigate there way around the gas plant, security fences and the pipeline system. The other 80 Hectares are dedicated to farm life such as cattle and sheep for grazing. They will soon be constructing more facilities that push • The Macarthur wind farm is put across three different properties which were previously used for the grazing of sheep and cattle • The area across the 3 different properties comes to a total of 5,500 hectors • The wind farm is placed in an area of which there is a considerable amount of wind
  8. 8. Wind energy (Non fossil and renewable) Gas energy (Fossil fuel and Non renewable) What advantages or disadvantages are there for each energy source? Pros - Natural gas energy can be switched on and off whenever you want in the matter of 6 minutes - It is near instant energy source, it can be accessed and used in minimum 6 minutes Pros - It is highly renewable - Once it is up and running it uses no green house gases - Wind turbines are duel use Cons - CO2 is put into the Atmosphere causing greenhouse gas - It is highly explosive - Using gas energy can be quite expensive Cons - During construction There was a large amount of green house gases was released into the atmosphere - It is Unreliable due to the fact that you don’t know when it will be windy - People of the community often complain about the wind turbines and the “Harm” they are doing.
  9. 9. Wind energy (Non fossil and renewable) Gas energy (Fossil fuel and Non renewable) Green house gas effect • During the burning of gas there is quite a substantial amount of CO2 is released into the atmosphere • During construction there was a lot of green house gases released into the atmosphere but what damage they did to the earth and the Ozone layer they repaid after 6 months of clean energy once the wind farm was up and running
  10. 10. Kyoto Protocol • The Kyoto Protocol treaty was something that was created in December 1997 in a city in Japan called Kyoto and came into force February 16th, 2005. • The Kyoto Protocol is a legally binding agreement under which industrialized countries will reduce their collective emissions of greenhouse gases by 5.2% compared to the year 1990 (but note that, compared to the emissions levels that would be expected by 2010 without the Protocol, this target represents a 29% cut). The goal is to lower overall emissions from six greenhouse gases - carbon dioxide, methane, nitrous oxide, sulphur hexafluoride, HFCs, and PFCs - calculated as an average over the five-year period of 2008-12. National targets range from 8% reductions for the European Union and some others to 7% for the US, 6% for Japan, 0% for Russia, and permitted increases of 8% for Australia and 10% for Iceland.
  11. 11. Social/economical/Environmental Impact Competitors Points Wind Energy • Wind farms can cost billions of dollars, the Macarthur wind farm came to a total of $1,000,000,000 • During the construction there was a lot of green house gases emitted but what damage they had done during construction of the Macarthur wind farm they paid back in 6 months of energy saving wind power • During the construction of the Macarthur wind farm there was a large amount of damage done to the roads • Farmers with a turbine/s on there property receive $12,000 a year per turbine as compensation • Wind turbines do not have the best reputation in everyone's eyes, there are myths such as that they cause head aches, they can kill birds in the area, they affect farmers cattle and that having turbines on someone's property can affect there real estate value, but again they are still just rumours and myths • Wind turbines have been known to be noisy for people close to them • Wind farms are often involved in community funds Natural Gas energy • Origin gas is the only one who earns a profit from there line of work • The Mortlake Gas plant has a high reading of green house gas that it emits CO2 • During the construction of the Mortlake gas plant all the constructers and engineers stayed in local motels which means the community was earning a profit
  12. 12. And the winner is……..
  13. 13. Evaluation • In conclusion to my presentation and after we have studied all this facts and statistics it is hard to say the wind power isn’t the superior energy source. Not only is it a clean and renewable energy source but it is a lot better for planet earth and it is also a lot cheaper to run once constructed. AGL would also have the be the superior competitor in the energy company brawl due to the fact that they seem a lot more community friendly the way they get involved with local things such as schools and cricket clubs but they also make generous donation to local community groups.
