Answer:
ADVANTAGES Coal · Most abundantly found fossil fuel · It is combustible as it is mainly composed of carbon DISADVANTAGES · It is a finite resource · Its use causes increase the level of greenhouse gases to global warming. NUCLER · Contributes less to the greenhouse ettect and acid rain than the conventional fuels. · The numerous safeguards make the risk of any accident minimal · There are potential health risks associated with proximity to nuclear stations. · An accident, if it occurs can kill and ruin an area for hundreds of years for example, Chernobyl. HYDEL · It is a renewable source of energy · It generates relatively cheap form of electricity · Dams are expensive to build · Electricity cannot be stored once it is produced WIND · It is non-polluting · After the initial expense of setting a wind farm, production of electricity is relatively cheap · Winds do not blow all the time and electricity generated cannot be stored. · The tall turbines spoil scenic beauty and are harmful to birds. GEOTHERMAL · This energy uses heat generated and stored beneath the surface of the earth · In certain places it is the main sources of generating heat and warming · The cost involved in producing geothermal energy is high. · It is limited to volcanic areas only. SOLAR · Solar energy is non- polluting. · It is an inexhaustible source of energy · The solar panels are expensive to put up. · If there are long periods of cloudy weather , it becomes a problem to produce energy
