Are fossil fuels being overused?

Extracts from this document...

Introduction

´┐ŻAre Fossil Fuels Being Over-used? In this case study I intend to answer the title question in full, using quotes explanations and visual evidence. Fossil fuels are used for creating energy to supply all homes with electricity, but also other places that need energy/electricity. These include; factories; football stadiums; theatres; office buildings. All of these places have a very high demand for energy. They need it for powering the lights, heating, machinery, photocopiers, fax machines, telephones, kitchens, sound equipment and other appliances. 3Coal, oil and gas are called 'fossil fuels' because they are formed from dead, prehistoric animals and plants. They are one of the main sources of energy used in life today, along with nuclear power, solar power, wind power; which most people think is recent although it has been around for about 4,000 years, as the Chinese and Babylonians used it for irrigating crops. Coal 1Coal provides around 33% of our energy needs and is used in fossil fuel power stations. First of all you burn the fuel (coal) to heat the water to make steam, then the steam turns the turbines and in turn the turbines turn the generators and then electrical power is sent around the country. As you can imagine, the coal needed to create enough heat and in turn, steam, to turn the turbines must be a hefty amount, which would result in an awful lot of sulphur dioxide in the atmosphere, as burning coal produces this gas. Sulphur dioxide* is a harmful gas that contributes to the formation of acid rain. Coal has got to be one of the most important items on the Earth, without it, we wouldn't have had much energy over the many years we have been using it. Although it could be debated that there could have been other sources of energy, such as the sun, although people only realised that this could be used for energy fairly recently. ...read more.

Oil Conclusion Now for the conclusion on oil and whether it is being overused, here it is. There weren't many facts that could tell us whether it was being overused, however from the small amount of facts that we did retrieve, we can assume that it is being overused. But this cannot be confirmed as, as I said before, we do not know how much oil there is left in the world, there could be quite a lot, then again there may not be a lot at all! Once we know how much oil there is left in the oceans, then we may be able to work out whether it is being overused, or whether it is just being used as much as it should be, but at the moment, I think it may possibly be being used a little too much. The only reason I am saying this is because lately on the news you hear that the prices of petrol are on the rise once again, meaning that it must be being used too much or else why would they raise the price per litre. You have to remember that price rations out scarcity, so if you raise the price, there may be people that are put off by the high price, however, petrol is a necessity if you have car, so instead of not re-fuelling, drivers may, instead, drive more economically and conserve their fuel. Natural Gas Now it is time to discuss the final type of fossil fuel, which is NATURAL GAS. Natural gas is discovered or collected in the same way as oil, as they are both stored as deposits deep, deep underneath the waters. 4Millions of years ago, the remains of plants and animals decayed and built up in thick layers. This decayed matter from plants and animals is called organic material -- it was once alive. Over time, the mud and soil changed to rock, covered the organic material and trapped it beneath the rock. ...read more.

Conclusion

To wrap up my conclusion, I am going to say that, YES, the fossil fuels are being overused, and as the word, fossil, says they can't just be reformed, they are fossils of dead plants and animals from millions of years ago, so if you were even going to begin thinking of when they may be back, you can forget your grandchildren's era, or their grandchildren, or their grandchildren, or theirs. I don't think they will ever be back, that is why they are non-renewable and will never be back! That is why I think we should slow down on their usage, especially if you want them to be here throughout your lifetime, because if we carry on using them at this rate, they could be gone in the next 50 years! Bibliography 1 BBC News stories I used this site for most of my information on the coal section of my case study. I think the info I got from here was quite extensive, and went into detail about what we use it for and how harmful it is to the environment. This site helped me come to my conclusion on coal. 2 Wikipedia I obtained this information on acid rain from the Wikipedia site, which has extensive knowledge on any subject you search for. I think you will struggle to find a definition that isn't on this huge internet encyclopaedia. 3 Energy Resources This website had little about what I needed but had the best about what was important, the definitions of scientific grammar. I just typed in what I needed and found this website and it was quite good. 4 Energy Kids Page This website was brilliant, and had loads of information, I loved it! It sorted the fossil fuels out into different sections and then sorted the information about the fossil fuel into sections, and was very neatly presented. ...read more.

    How are products from oil obtained and used?

    4 star(s)

    Substances with very high boiling points (e.g. bitumen and fuel oil) condense immediately and are tapped of at the bottom of the column. These fractions not only have the highest boiling point, but are more difficult to burn and have the smokiest flame; they also have the largest molecules meaning they have a higher viscosity.

  2. air pollution

    The Earth cannot retain this heat, so it eventually releases it. Much of the heat does not make its way back through the atmosphere, and becomes trapped due to greenhouse gases such as carbon dioxide. This results in the rise of the global temperature.

  1. Are humans to blame for Global warming or is it a natural phenomenon? ...

    This would result in certain parts of the earth receiving more solar radiation and getting warmer and could result in climate change and the change in global temperature. The sunspot theory A sunspot is spot or patch in the sun that occur from time to time on the surface of the sun.

  1. GM foods - Harmful or Helpful

    Some foods have been genetically modified to be herbicide tolerant as it is more cost effective for farmers than to spray different herbicides in large quantities which will only kill weeds. These new foods also protect the environment from dangers of agricultural waste and run-off.

  2. Should the UK government continue to invest in Nuclear power?

    To generate more power, the rods are raised and more neutrons can crash into uranium atoms.

  1. Are Electric Cars better for the Environment?

    However, even here the picture is mixed, and wholly dependent on how electricity is generated in the country the car is being driven in. It can even depend on what time of day the batteries are charged because night-time electricity is less dependent on coal.
