1. Fossil Fuels are natural fuels such as coal or gas that are formed in the geological past from the remains of living organisms. Fossil Fuels are formed from plant and animal decay that has been converted to crude oil, coal or natural gas.
2. Coal, oil and natural gas are all examples of fossil fuels that are used in Australia and all over the world. Coal is Australia’s primary fuel source for generating around 73 percent of Australia’s electricity. It is also used in cement manufacturing, food processing and paper manufacturing. Oil in Australia is mainly used for petrol, diesel and kerosene. It is also used in the production of plastics, synthetic fibres like vinyl, nylon, acrylic and polyesters. Natural gas in Australia is mainly used in power stations to produce electricity. It is also used to provide heat for comfort and hot water.

Peak oil is the hypothetical point in time when the global production of oil reaches its maximum rate, after which production will gradually decline. Three impacts that ‘peak oil’ will have on the society include the fact that humanity's way of life will be forced to change, products made by oil such as plastic will become rare and the fact that peak oil will have a great impact on food production. Three impacts that ‘peak oil’ will have on the environment include the fact that if oil runs out the world will need another source of energy so they have to dig more to find another source of energy, To extract oil from sandy tar deposits deposits, these places are usually strip-mined—which means the forests and wildlife on the surface are completely cleared away, In the refinement process a lot of fresh water in polluted, turning blue water to
Coal, crude oil, and natural gas are all considered fossil fuels because they were formed from the buried remains of plants and animals that lived millions of years ago.
The term “peak oil” refers to the point when oil production reaches its maximum rate and then its production gradually decreases. There is no doubt that having cities as peak oils will drastically affect many lives. But what exactly are the effects of peak oil? There are many effects that could possibly end the lives of many. One would be that peak oil will affect health services. The Gross Domestic Product or simply the GDP will decline as a result of peak oil. When the GDP declines, it will affect what communities can spend on health care and other social health activities and programs. Most models of health care provisions depend on cheap fossil fuels. Since peak oil will decrease the quantity of oil and as a result increase the prices,
Most people have a theory that the fossil fuels we have today are from the remains of dead dinosaurs. Which is in fact not true, but what is true is that these fossil fuels were at one time alive. They formed when prehistoric animals and plants died and were covered by rock and other plant growth (energy.gov 2014). Organic matter, along with varying temperatures and pressure worked together to produce the fossil fuels. Different types of fossil fuels were developed depending on how much pressure and what the temperature was involved at the time of the forming of these fossil fuels. (energy.gov 2014). These fossil fuels, what are today known mainly as coal, oil, and natural gas, were the different types of fossil fuels that were developed and which are the ones that are still being used today. According to the U.S. department of energy, oil and natural gas were formed from living things in the ocean, which were then buried under the ocean sediments. Later, the seas and oceans evaporated and they began to compress with heat and pressure under the silt, which is how oil was formed. With that, some of the oil continued to sink underground and kept compressing and causing pressure, which in turn produced natural gas. Coal formed from the dead remains of trees, ferns and other plants that lived 300 to 400 million years ago. In some areas, such as portions of what-is-now the eastern United States, coal was formed from swamps covered by sea water.
Fossil fuels are a fuel that was formed over millions of years from organic material from forms of life. There are different types of fossil fuels such as gas, oil, nuclear and the one mostly produced in Australia, coal. Australian government supplies energy from fossil fuels to the entire country as around 86% of electricity is generated from these fuels, with 73% from coal and 13% from natural gas with renewable energy sources making up 14% of Australia’s electricity (origin,2015). Fossil fuels have advantages such as the reliability and efficiency because they generate huge amount of energy which is more reliable (Rinkesh,2009). They are also safe with easy transportation on large trucks or pumped through large pipes. However, fossil fuels
What most people in our society lack to notice is how our country 's continuous use of fossil fuels is endangering to nature and the wildlife it inhabits as well as the environment that we live in. Our society seems to think that fossil fuels we use in excess today will last forever but actuality will one day be depleted to unrepairable measures, which is why we need a cleaner more environmentally friendly substitute. With that said my paper is going to underline how our society would be able to transfer from fossil fuels to cleaner energies which are beneficial to our earth and existence.
Today, many rely on fossil fuels to help with daily necessities such as delivering electricity, powering vehicles, and heating their homes. Fossil fuels have been widely used since the Industrial Revolution. Since then, the use of fossil fuels has greatly grown. Fossil fuels are any naturally occurring carbon-containing material that, when burned with air produce heat or energy that can be converted into liquid fuels and other hydrocarbon (carbon bonded to hydrogen) products (Speight, James). There are three main types of fossil fuels which can all be used for energy delivery: coal, oil, and natural gas. In 2012, fossil fuels made up about 87% of the world’s primary energy consumption. The most consumed fossil fuel was oil. Oil was consumed
As known, fossil fuels are an organic material created from dead organisms and the remains of flora and fauna within the Earth’s crust. Coal was created from dead trees and other plant materials whereas crude oil and gas were created from dead marine organisms called plankton that were exposed to huge pressure and heat deep within the planet for over millions and millions of years. From about the year
“Peak oil” refers to when the rate of production of oil will reach its highest rate and decline gradually. If our production declines after the peak of oil and demand continues to increase, scientists say we will fall into an oil shortage. Many experts think we are about to pass the production peak for oil since Hubert’s peak was proved to be accurate, every since 1970, U.S oil production peaked and has continued to decline ever since. Factors of this problem were the discoveries of new oil fields that peaked 30 years ago, but we still continue extract and consume more oil than we have been finding. In addition depending on year to year use for production, would make us unable to realize that we have pasted the peak of oil production until four years after, so we wouldn’t even known if we passed the peak or not. For example many oil companies and government are untrustworthy about the amount of oil reserves there are, and the estimated difference on how much we can extract based on how much oil there is. Also, a U.S geological survey report shows that there are about 2 trillion barrels of oil left in the world and not 1 trillion. Developed countries such as the U.S continue to use this limited supply of oil because their demand is increasing rather than a developing country where they are beginning to industrialize. One thing is
A fossil-fuel power station is a type of power station that burns fossil fuels such as coal,natural gas or petroleum (oil) to produce electricity. Central station fossil-fuel power plants are designed on a large scale for continuous operation. In many countries, such plants provide most of the electrical energy used.
Fossil fuels were formed 300 millions of years ago before the time of dinosaurs (Energy Quest, 2012). Prehistoric plants and animals formed the fossil fuels millions of years ago (U.S. Department of Energy, 2013). There are three main fossil fuels that we use oil, coal, and natural gas (Energy Quest, 2012). Fossil fuels are non renewable because they take many millions of years to make (Energy Quest, 2012). Also, once the fossil fuels are made, they can never be made again. That is why many people try to save energy by conserving energy (Energy Quest).
According to Energy and the Environment, fuels refers to anything which are able to burn as a source of energy. Fossil fuels have discovered and used since early eighteenth. The main three fossil fuel are coal, gas, and oil. They have been formed from the remains of ancient prehistoric plants and animals more than 300 million years ago at beneath the land or the ocean floor. The energy had stored in fossil fuels are originally coming from
Fossil fuels are defined as hydrocarbons primarily coal, fuel oil or natural gas, which is formed from the remains of dead plants and animals. When these fuels are burnt, the energy released can be harnessed to produce electricity. Fossil fuels are the most popular form of energy as they have very low ignition temperature. All fossil fuels undergo through the process of combustion. Combustion necessarily requires oxygen. All the reactions are exothermic in nature which therefore means they give out heat and sometimes light. The constituent hydrogen and oxygen react with each other chemically and produce high amount of heat and energy. Different fossil fuels burn at different rates because the structures of the hydrocarbons are different in each of these compounds. However, one common by-product of each of these fossil fuel is carbon dioxide.
Peak oil is described as the point in time when the maximum rate of petroleum extraction is reached, and at this point we assist to a diminution of the resource. Oil is one of the world 's most vital resource, we use it in every aspect of our daily lives, we use it for electricity, gasoline and even drugs. The disappearance of this resource can lead to a major global disaster. In an attempt to identify the potential impact of such a disaster and find alternatives energetic resources, a cloud of researchers started to focus their research around this topic. While the first researches made on peak oil where mostly focused on its plausibility, nowadays researches concentrate on determining the exact period of occurrence, as well as the economic and political impact of this event.
"What we can be scientifically certain of is that our continued use of fossil fuels is pushing us to a point of no return," warns President Obama, “we are condemning future generations to global catastrophe.” The point of no return metaphorically represents the place in ones journey that must be continued with no alternative routes or ability to make change. In consort with President Obama, many scientists believe the point of no return could occur if significant efforts aren’t made soon. Anthropogenic (human influenced) activities in comparison to natural influences have more of an impact on the environment. Since the industrial era carbon concentrations in the atmosphere have increased by thirty percent. The burning of fossil fuels and deforestation are the two largest human caused contributors to high carbon concentration levels (NOAA). These harmful emissions causing an increase in the global average temperature and pace of glacial melt. The majority of environmental scientists believe that climate change is solely anthropogenic, yet some critics claim it is merely a natural occurrence that humans have no control over. The vast population growth has increased the demand for available natural resources. Although these resources are crucial to our everyday lives, sacrifices must be made to reduce harmful emissions. To ensure the safety of future generations, human activity must be recognized as the primary cause of climate change in order to take appropriate action to
The three type of major fossil fuels are coal, oil and natural gas. These fossil fuels are considered non-renewable energy because of the length of time it will take for the natural processes to create these resources. It will take millions of years for them to form. Most of our coal was formed about 300 million years ago, when a majority of the earth was covered by steamy swamps. As the plants and the trees died, the remaining of the plants and trees sank to the bottom of the swap which accumulated layers upon layers. These layers eventually formed a soggy, dense material called peat. Over the millions of years, the earth’s surface, seas, and great rivers changed and caused deposits of sand, clay and other sedimentary rocks were formed. The pressure caused the weight to squeeze water from the peat. The deeper burial and heat associated with it steadily changed the material to coal. Scientists have also estimated that 3 to 7 feet of compacted plant matter is required to form 1 foot of bituminous coal. (COAL: Ancient Gift Serving modern Man, 2005).
