Introduction

Research on Energy Resources 3.5.4 Coal Fired Power Stations Coal-fired power stations are responsible for the diffusion of greenhouse gases such as carbon dioxide. The amount of carbon dioxide in the atmosphere must be carefully balanced to maintain the greenhouse effect, which is what keeps the surface of the earth warm enough to support life. Like all things in nature a change in one part of the environment can result in changes in another. The effect of increased greenhouse gases in the environment is that the temperature of the atmosphere is expected to increase. It is predicted by some scientists that this temperature increase could result in the following: * The destruction of ecosystems such as the Great Barrier Reef. * A change in the world's weather patterns, resulting in an increase in both intensity and frequency of storms, cyclones, floods and droughts. * The melting of glaciers and polar ice. * Rising sea levels resulting in the permanent flooding of vast areas. ...read more.

Farmers can produce electricity as a secondary source of income. * Visual Impact - The visual impact of wind farms is difficult to avoid. However, careful planning that takes into account such things as the placement of wind farms, ensuring that all the generators are the same and that the blades all rotate in the same direction, can help reduce their negative visual impact. It is worth noting that a coal-fired power station is also not visually pleasing. * Noise - Wind farms are usually located some distance from residential properties and therefore noise is not usually a problem. Tidal power Research into the environmental impacts of tidal power is limited. There is concern that the use of tidal power can result in the silting up of waterways and fish are killed as they swim through the turbine blades. 3.5.5 Coal-fired Power Stations Advantages * Coal is a relatively cheap source of energy. * Electricity supply is reliable. ...read more.

Conclusion

* Weather conditions affect the performance of solar collectors. Wind Power Advantages * Wind energy is an indirect form of solar energy and therefore is free. * It is a renewable energy resource. * There are no dangerous emissions. * Wind power can be used in remote areas. * Wind power can be used in conjunction with other renewable energy resources such as solar energy. Disadvantages * Wind turbines need to be built in areas where there is a reliable source of wind. * The wind speed can be too fast or slow which means that electricity is not produced. Also the wind does not blow all the time. * Wind farms can be a visual eyesore and may create excess noise. * Wind turbines can be expensive to maintain. . Tidal Power Advantages * Tidal power does not produce greenhouse gases. * Tidal power is a renewable energy resource. Disadvantages * Tidal power plants are expensive to construct. * Dams used in the production of tidal power can raise tide levels. * Raised tide levels can flood the shoreline affecting the marine population.
