Gas versus Wind as an Energy Source - Teika

  1. 1. VCE ENVIRONMENTAL SCIENCE UNIT 3: ENERGY AND GREENHOUSE GASES BY TEIKA Area of Study 1 SAC 1B: A comparison of a fossil fuel and a non-fossil energy source
  2. 2. FOSSIL FUEL VS. NON-FOSSIL ENERGY SOURCE Fossil Fuel Non-Fossil Energy What is Fossil Fuel? Fossil fuel are found deep under ground. There are many types of fossil fuels. Fossil fuels are a natural. Crude oil, natural gas and coal are fossil fuels. Fossil fuels are very precious resources because they are non-renewable object once you have used them they cant come back. Most fossil fuel are found underground which has been producing for quite a number or years. This is why there is a limited resource. What is it? Nuclear,Hydro,Wood, Bio waste, Ethanol, Geothermal, Solar, Wind. Are non-fossil energy. These can do more than one thing during the process they are used for as Non-fossil energy is much better for the environment and better in the long run when you have your children grow up in the some what future. Non-fossil energy Is made from everyday uses. Why let light and wind go to waste. Solar panels help produce heat and power making the climate a lot healthier and liveable. Fossil fuel advantages are often considered to include ease of production. These are more common but aren't reliable because there isn’t always wind and sun.
  3. 3. • MODIFICATION OF LAND USE Wind farm Mortlake gas plant Wind farm is much more renewable as they can still run as a normal farm with livestock or crops on the land still as the turbines don’t use that much space and allow no disterbences to the land onc constructured. Mortlake seems to use quite abit of land. 120 aches is used but only 20 aches
  4. 4. SOCIAL AND MEDIA IMPACT noise quality- During the production and still today both macarthur and mortlake make a fair amount of noise. This Is why they built and construction a fair way out of town so That there isnt much disturbance when running. air quality- is another reason as to why they put them out of town. environmental quality- also is a reason
  5. 5. NATIONAL STRATEGIES The national strategy were to limit greenhouse gas emissions, conserve and enhance greenhouse gas sinks, improve knowledge and understanding of the greenhouse effect and prepare for the potential impact of climate. They then replaced in late 1996 by. This is to help reduce the greenhouse effect admission. This is to help prevent pollution.
  6. 6. EXTRACTION Mortlake gas plant: the gas is more efficient, but unfortanally wont last forever. Gas produces more greenhouse effect admission. Gas is used in your house for heaters and cooking with a gas oven. However this is not a long term solution as gas will evently run out or become more expensive as they find it hard to find as it unfortanally takes a fair amount of years to produce. Macarthur wind farm: wind farm is efficient but not reliable because there isn’t wind around all the time. However this is more safer for the environment because it’s a non- fossil fuel. Wind is sometimes better than other days, just like heat from the sun. when using solar panels if you have a cold day without any sun then your water isn’t going to be hot, just when you want a hot shower after a long day at work.
  7. 7. TRANSPORT Mortlake: transportation for Mortlake when construction was carting all the products this made a disturbance in the road. Wind farm: when transport was made during the process of production. Traffic was stopped as having to get the huge pieces of the wind turbines to allow construction to happen. But once reached to the location of the Macarthur wind farm they then have done one bit of transport to make the machinery that will then make electricity. When all the trucks were going through it made it hard in which to travel along the road. This made more work for the workers as they had to re-build the road. If using simple things like – removing unnecessary products in your car or truck will lighten the load. This is why when construction was going on for both places it damaged the roads.
  8. 8. USE Mortlake: At 550 MW, the Mortlake Power Station is the largest gas-fired power station in the state. Macarthur: Proposed as the largest wind farm in the southern hemisphere, the farm will generate up to 420 Megawatts of electricity through 140 Vestas V112-3.0MW wind turbines – enough energy to power around 220,000 average Victorian homes each year This is used for houses and business’s around the community area-
  9. 9. ECONOMIC IMPACTS Macarthur and Mortlake- both had a big scale of business as having to employee people from across Australia and some from other states needed a place to stay. The Macarthur accommodation flats were booked out the whole entire time of production. This was a huge benefit for Macarthur. This would have been the same in Mortlake. Macarthur only has the one shop called Mooneys which is a milk bar. There business would have double if not tripled in their income during this time. Not just the milk bar benefitted but so did the pub. This was a positive thing for the milk bar and gave them a good profit. As they finished production in dropped of for the profit for Mortlake and Macarthur. As employing less and less people it then become more quite for the accommodation places and small business who extremely benefited, but unfortanally this wasn’t forever. When people hear about Macarthur or Mortlake they know about it having the wind farm of the gas plant. This is what the town is now known for.
  10. 10. SOCIAL IMPACTS Macarthur wind farm: more hands on, more employees and employment opportunity. Mortlake: not as many jobs, when construction was done there was a lot of distraction for Mortlake but had a lot of job opportunity's for the district but then was only for a short amount of time then most of them were out of jobs because they put them of once contruction was made. This also was the same situation with macarthur wind farm. This left people angry as they were out of jobs .
  11. 11. ENVIRONMENTAL IMPACTS Wind farm: the surrounding farmers have complained majority of the noise and generally have a big concern for all the dead birds in which have been found on the ground near the turbines. The farmers have also complained about there dogs not liking it. The environmental impact is very low because farmers can still product there ‘summer crops’ or keep there stock there. This makes the land still the same as the wind turbines weren't even on the land. This is what negative they thought would happened during the planning stage, risk of the proposed wind turbines to threatened waterbird species, including the Pied Cormorant, Whiskered Tern, Sharp-Tailed Sandpiper, Brolga, Great Egret, Australasian Shoveler, Hardhead, Musk Duck and Latham’s Snipe; impact of the proposed wind farm on the values of the region’s volcanic landscape; risk to archaeological and related Aboriginal cultural heritage values of the proposed wind farm area; and potential implications for the amenity of surrounding residents. Mortlake: Mortlake land has 2/3 of the land just wasted as they have to have a curtain amount of spaces between crops and stock. They have 120 aches and only use 20 that is a big amount that is just wasted. Mortlake would take up more space and more resources compared to Macarthur. (The power station’s natural gas supply is piped via an 83 km dedicated underground natural gas transmission pipeline from the Port Campbell area.) this would have caused a lot of disturbants when construction as they would have had to go place the pipe’s down.
  12. 12. REGIONAL IMPACT The regional impact in Australian and new Zealand are: • By 2020, significant loss of biodiversity is projected to occur in some ecologically rich sites, including the Great Barrier reef and Queensland wet tropics. • By 2030, water security problems are projected to inensiry in southern and eastern Australia. • By 2050 ongoing coastal development and population growth in some areas of austraila and new Zealand are projected to exacerbate risks from seas levels rise and increase in the severity and frequency of storms and coastal flooding.
  13. 13. CONTRIBUTION TO GREENHOUSE EFFECT Macarthur: Mortlake would be more energy efficient. Macarthur wind farm isn’t hurting the environment as much as digging up coal and gas. There is only a certain supply of them. We want something that will last for generations to come. Mortlake:
  14. 14. INTERNATIONAL AGREEMENTS Kyoto protocol- is an international treaty that sets binding obligations on industrialized countries to reduce emissions of greenhouse gases. According to the UNFCC website, the Protocol "recognises that developed countries are principally responsible for the current high levels of Green house gas emissions in the atmosphere as a result of more than 150 years of industrial activity, and places a heavier burden on developed nations under the principle of 'common but differentiated responsibilities'
  15. 15. NATIONAL STRATEGIES  Australia will actively contribute to the global effort to stabilise greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous interference with the climate system and within a time frame sufficient to  •allow ecosystems to adapt naturally to climate change;  •ensure that food production is not threatened;  •enable economic development to proceed in a sustainable way  This is what they are aiming to do with the national strategies  1. To limit net greenhouse gas emissions, in particular, to meet our international commitments.  2. To foster knowledge and understanding of greenhouse issues.  3. To lay the foundations for adaptation to climate change.
  16. 16. STATE POLICIES The rules and regulation that they have to apply to is. Making sure that customers are satisfied and no complaints have been made. They also have to meet the OH&S. Workers must wear protective clothing on.
  17. 17. LOCAL STRATEGIES Macarthur: surrounding farmers weren't to happy about the suppose noise that they are meant to produce. The local strategies when planning was taken place as they need to keep in mind before production. This is what the Macarthur local strategies was: The municipal overview recognises the geographic location, physical characteristics, historic development, and population characteristics of the shire. This section recognises the area between Hawkesdale and Macarthur, as being located partly within the Stony Rises and partly within the Volcanic Plains. The overview discusses the indigenous and post-European settlement of the municipality. It also explains the importance of tourism along the coast and the focus of agriculture throughout Mortlake: Mortlake provides a way that they are going to try and help meet morlakes population satisfactory to provide the community, comfort. This is what they have on the moyne shire website: In an effort to ensure clear communication, Moyne Shire Council has established the Mortlake Power Station Community Engagement Committee, which includes community members, Councillors and Council staff, and the power station builders Origin Energy and Bilfinger Berger Services. The committee meets regularly and disseminates regular community update bulletins to Mortlake and district residents. This helps everybody in the district that is unhappy.
