Introduction: Right from 1800’s, when steam engine was developed, Power industry went through many developments. Yet, power generation has social challenges and environmental problems.In this report, I shall cover the different types of Power Generation and also their relative advantages and disadvantages.Different Types of Power Generation:Non-Renewable resources:•Coal Power Generation•Nuclear Power Generation•Natural Gas Power GenerationRenewable resources:•Wind Power Generation•Geothermal Power Generation•Solar Power Generation•Biofuel Power Generation•Hydro Power GenerationNon- Renewable Resources:These constitute the power that is generated from sources limited in availability and which exhaust over a period of time upon continuous use Examples - Coal, firewood, fossil fuels and other minerals. Renewable Resources:These constitute the power that is generated from sources unlimited in supply and which won’t exhaust with continuous use . Examples - solar energy, wind energy, hydro energy, geothermal energy, etc.
Scenario in USA:Source: Wikipedia
Coal Based Power Generation:This is one of the ancient methods of power generation. Cost Factors:Fuel Cost:Coal is cheap compared to other fossil fuels such as Diesel and Natural Gas. Yet, the transportation cost of Coal to the power plant is high. Construction Costs:Construction cost if high because of the installation of equipment like boilers, cooling towers, steam and gas turbines.Environmental Issues:Air Emissions:They emit harmful greenhouse gases like Carbon Dioxide (CO2¿, Carbon Monoxide (CO) , Sulphur Dioxide (SO2¿and Nitrogen Dioxide (NO2¿which cause global warming and also increase the acidity of the atmosphere leading to Acid Rain.
Waste Generation:The combustion of coal produces ash which is a combination of metal oxides. This ash disposal process leads to solid waste generation. Overall Opinion:“Thermal power plants have been the most reliable source of power supply for the past hundred years. It will continue to do so in the future aswell, given the wide availability of coal and the simple technique involved in power generation. However, thermal power plants still require a number of developments and there is a huge scope for development especially in reducing the carbon dioxide emission and in solid waste management.”NATURAL GAS POWER GENERATIONAnother way by which power can be extracted from fossil fuels is through natural gas. These power plants are very similar to the coal power plants in operation. Natural Gas produces nearly 30% of the total energy produced in the United States.
Economic Factors:Fuel Cost - HighConstruction Cost – HighIndirect Costs – Too much involved.
