Wind energy is one of the most commercially reliable and cost-effective renewable energy (RE) resources available worldwide and its utilization in Australia is undoubtedly an advantageous prospect. Initially, the generation of wind energy is produced through the motion of air from high pressure to low pressure, as this progression is a direct consequence of the solar heating of various parts of the Earth's atmosphere and its planetary motion, thus resulting in the air being deflected to the right in the northern hemisphere and in the opposite direction in the southern hemisphere (Duffie and William, 2013). It is generally observed that wind power generation is the best suited source for Australia's future as it is clean, low-cost (in …show more content…
The final statistical results displayed that the maximum wind speeds were observed at Tasmania's Macquarie Island weather station (10.2 m/s) and its approximate electricity price ranged from AUD$0.25/kWh to AUD$0.4/kWh whilst, the energy production in Northern Territory proved to be of no possibility in both economics and environment as its energy production made no contribution at all (except for the grid) (GM Shafiullah et al, 2011). Therefore, as Tasmania ranked the highest in all relevant areas, it is concluded this state is the most suitable location for the construction of generation of wind energy (GM Shafiullah et al, 2011).
Just as there are positive benefits from utilizing this renewable source, there are also some key disadvantages associated with wind energy generation which should be considered. Firstly, the effect of visual impacts depends not only upon the outward appearance of the turbines, but also the individual's personal attitudes to their presence (G.M Shafiullah, 2012). Similarly, a study conducted by Gourlay (2008) showed that the majority of the UK population (approximately 70%) had displayed a positive outlook
In Australia, carbon emissions contribute to the problem of global warming and climate change worsening. Therefore, people want to move to a more sustainable energy future, because renewable energy is the only valid method to reduce emissions. But it is very difficult to widely use renewable energy since this transition have to face numerous barriers. This essay will argue that adopting renewable energy cannot be overcome due to lack of financial and political barriers.
If wind turbines are supposed to be good for the environment, what is to be said about their lethal effects on birds? How about the noise produced from the large turbines, whom many consider to be horrible eyesores that tarnish the countryside? Investing in these large, hideous structures is initially expensive, and while it may be true that there is an unlimited supply of wind, how is the resulting energy to be distributed? Undoubtedly, just as the advantages of wind power need to be taken into account, the disadvantages also need to be
In a growing world, electricity production is becoming a problem due to coal fired electrical plants releasing millions of gallons of greenhouse gases, ecological problems with pollution in water, and health risks concerning workers and people living nearby. But with new technology and advances in renewable energy sources, wind energy is becoming one of the most popular energy sources for many states.
3. Some people think wind power is good , as it’s clean energy. But some people think it can cause health problems.
One of the fastest growing energy sources in the world, wind power is a globally advantageous renewable resource.
With the increasing Australia’s population the demand for reliable energy to support our power needs now and into the future is escalating, with majority of the Australia’s energy depending solely on coal power with concerns arising on whether this is the best option for Australia’s future or focus more on harnessing green renewable energy. This essay will argue that green energy is the best option over coal power, for the world and Australia’s future, such as solar and wind. The biggest challenge though will be finding a way in being able to harness the resources nature provides to support the growing demand.
One of the great parts about wind energy is that it has a large amount of positives to the environment and hardly any negative effects. Because wind energy uses the wind for the energy there is no emissions generated from the energy produced. It is estimated that the use of one million kWh of wind power can save around 600 tons of carbon dioxide emissions (Saidur, Rahim, Islam, & Solangi, 2011). Therefore, it is easy to see that the widespread use of wind power can help mitigate climate change. This is critical to help stop climate change and the United States is uniquely positioned to be the leader in curbing climate. When the United States starts heavily investing in alternative energy sources other countries will likely follow suit, which will be key to reducing global emissions.
As a first world country, Australia is one of the main counties that use tons and tons of electricity. 73% of Australian community uses the electricity generated from Coal and 13% of the Australian community uses the electricity produced using natural gas and only the other 14% uses renewable energy sources such as wind energy, solar energy, geothermal energy etc. Therefore a majority of Australians use non-renewable energy sources. The total amount of energy used by the Australian community is around 226.9 billion kWh per year. Therefore, 195.134 billion kWH of energy is generated from non-renewable energy and only 31.766 billion kWH of energy is generated by renewable energy in Australia. To produce the total amount of energy
Nowadays, there are two fastest growing sources of renewable energy which are wind and solar that produce intermittent supplies of energy. People tend to demand from energy more than before. Renewable energy in Australia deals with efforts being made in Australia to quantify and expand renewable energy, which includes electricity, transport fuels and thermal energy. Total renewable energy consumption in Australia in 2015 was 346 Joules(PJ), representing 5.9% of Australia's total energy consumption.(2015 Australian Energy Statistics) This is an increase of 1.6% from 2011–12 levels (265 PJ), representing 4.3% of Australia's total energy consumption.(2013 Australian Energy Update) The energy consumption increases is not only due to the rate
The path to renewables in Australia in recent times has been met with a somewhat contentious debate. In a time where “No challenge poses a greater threat to our future than a changing climate.”(Barack Obama, August 3, 2015) the plight of Renewables is of more importance than ever in our history as a pillar on to which our highly carbon emitting society must rest, if we ever seek to reduce the impact on our climate both government and individuals must seek out and adhere to serious carbon abatement strategies. The idea of previous successful government involvement in the renewable energy industry through regulation and initiatives may elude the everyday modern Australian, marred with controversial schemes, which in hind sight were rolled out to fast without sufficient regulations has seen relatively recent schemes reduced or even thrown out. However, it is best to remind ourselves that some of Australia’s rite of passage as a nation were through Renewable energy projects. Examples of this such as the Snowy Hydro Scheme which at the time was named as one of the civil engineering wonders of the modern world and the White Cliff Solar Power Station which can be seen as a world first solar energy provider.
There are many opportunities for energy extraction in Australia, which may or may not be currently being benefited from. The issue of energy today is what the current situation of energy in Australia is and how it will improve or decline in the coming years. The subjects which are contributing factors are the current exploitation of non-renewable energy sources, how renewable sources are being used in Australia and what the Government’s energy policy is and also what the RET is.
“A wind turbine is a machine for converting the kinetic energy in wind into mechanical energy”. (1) The inventor of the first electric wind turbine was Clevelander Charles Brush, who ran his entire Euclid Avenue mansion off of one for 20 years, which later made the cover of Scientific American in 1888. (2) Although the use of alternate energy didn't rise a great deal afterward, this event did open the eyes for many environmentalists. Wind power is only one of our several “energy source[s] whose ‘fuel’ is free and will never be exhausted” (3) with the pros and cons not completely weighed out as to whether it will be truly beneficial or not. The two main issues regarding wind turbines are the environmental effects that they have and the
We are facing an energy crisis on Earth. Burning fossil fuels are harming the atmosphere; this global warming and affects produces chemicals that hurt our body. People are starting to think about using alternative energy. Wind power would be our first choice, because it’s clean, inexhaustible and renewable. Today, wind power is mainly used in Europe. We believed wind power would be the main source of alternative energy for world use.

Wind power is a clean and renewable energy that, while at times unreliable, has very low upkeep cost and is growing at a rapid rate. While there is currently enough wind power to provide many times our current energy need, it is unfeasible in reality. Wind power utilizes the kinetic energy of air and uses it to power a generator to produce electricity. Even though dependence on wind power is impossible, it still can provide a strong, clean, quantity of power to supplement current energy production.
