Comparison and Evaluation Of Energy Sources

Introduction

Comparison and Evaluation Of Energy Sources Compare and contrast particular advantages and disadvantages of using different energy sources to generate electricity At this point in time there are four options being considered to produce power for us instead of the two standard methods. Firstly, however, lets look at those two conventional means of producing power: In the United Kingdom, the method used most widely is by burning fossil fuels. 70% of the electricity for the United Kingdom is produced by 70 coal fire power stations. The fossil fuel, coal, is burnt in a large furnace, and the boiling tube is placed above it. ...read more.

Middle

There are also great environmental costs that are paid as it releases poisonous gases: carbon dioxide and sulphur dioxide. For the same amount of energy released, coal produces more carbon dioxide than oil, which produces more carbon dioxide than natural gas. There is no realistic way of preventing the release of carbon dioxide into the Earth's atmosphere. The sulphur dioxide produced will also get into the atmosphere and cause acid rain, which can have very devastating effects. The sulphur can be removed from the fuels before it is burnt but that produces much more expensive electricity. ...read more.

Conclusion

Nuclear fuels do not produce gases which increase the greenhouse effect or which help to produce acid rain. When nuclear power stations are running well, very little radiation or radioactive material escapes into the surrounding area, but if there were an accident, however, large amounts of dangerous radioactive substances may be released over a wide area. Nuclear power stations also produce waste, some of which can, and will, stay dangerously radioactive for thousands and thousands of years and so it obviously has to be stored very safely and carefully. Yet for both energy sources, it takes 12 hours for the generators to reach full capacity, and the electricity can't be stored without another great loss, whilst more still is lost in pylons and the movement of electricity. ...read more.

This allows them to be more active, and show a variety of complex behavioural patterns based upon prevailing temperature conditions.
