Extracts from this document...

Introduction

What are the problems caused by fossil fuels and are the alternatives any better? Fossil fuels are fuels that were formed millions of years ago. The three fossil fuels known to man are coal, oil and natural gas (methane). Because these fuels were formed millions of years ago, many contain fossils, hence their name. Fossil fuels are also a non-renewable fuel; this means that they have a finite supply (one day they will run out). One of the fossil fuels, oil is the main energy supply of the world. This means that it is being consumed at an alarming rate. An alternative to fossil fuels is renewable sources of energy such as solar power and bio fuels. Renewable fuel is inexhaustible but cannot always keep up with supply and demand. ...read more.

Middle

When animals died, they sank to the seabed and were covered by sand and mud. As time passed, the remains of the creatures turned into oil and the sand and mud turned into rock, containing the oil within the rock. Oil has to be reached by drilling a well using a drilling rig. Because so much oil is used, scientists believe that within 50 years, the world's oil supply will have disappeared completely. The USA, which was once rich in oil, now has to buy oil from other countries, such as Saudi Arabia in the Middle East. Most of Britain's oilrigs are in the North Sea. Fossil fuels cause environmental problems with the Carbon Dioxide they release when burned. ...read more.

Conclusion

To be efficient at energy however, it needs continuous sunshine. Nuclear energy is renewable in a sorts, with reprocessing plants dealing with radioactive waste. Small amounts of nuclear fuel produces large amounts of energy. However, nuclear radioation is dangerous and high safety standards are needed. The waste materials from the power plants stay radioactive for thousands of years. A nuclear reactor speeds up natural nuclear reactions in radioactive materials. The heat generated by these reactions is used to produce electricity. All forms of energy production has its advantages and disadvantages. Fossil fuels and nuclear energy have the worst side effects and so, alternatives must be found. Other types of alternative energy sources have little or no effect on the environment. They may cost a lot, take up land and 'spoil' the scenery, but this is a small price to pay in order for our planet and way of life to survive. ...read more.

    Summer time atmospheric phenomena Before one can talk about the overall levels of air pollution associated with Moscow it is crucial to consider several atmospheric phenomena that contribute to the current pollution status. Moscow as a large city experiences the effect of the "heat island" where the annual temperatures

  2. Environmental Problems

    One is the idea of conservation, the idea that humans should put natural resources to use, but should manage them wisely. Another is the preservation theory, the concept that wilderness should not be altered by humans. Although these theories are ideal and favorable, it is based upon the idea of

  2. The World Demand for Power

    The entire Earth, land and sea, has been searched for oil 'reservoirs' and once found as much oil as possible is extracted. Oil Extraction As we have said 'the end of the tank' is approaching. One interesting application of Physics is now being used to defer this time.

  1. Discuss the Advantages and Disadvantages of being Ectothermic and Endothermic for Vertebrates.

    Terrestrial ectotherms have to contend with greater temperature fluctuations than those of the aquatic ectotherms, but they have the benefit of living at higher environmental temperatures. This allows them to be more active, and show a variety of complex behavioural patterns based upon prevailing temperature conditions.

  2. Discuss the Advantages and Disadvantages of being Ectothermic and Endothermic in the Vertebrates.

    This is practised by endotherms, but ectotherms have become very highly specialised at this form of internal regulation. The mechanisms are relatively simple: for example the movement of lizards forwards and backwards between sun and shade. The amount of heat radiation absorbed can be altered by changing colour (for example in chameleons)
