Geothermal Energy Case Study Example | Topics and Well Written Essays - 500 words

Geothermal Energy - Case Study Example ates electrical power by utilizing the thermal energy from earth and converting it to the electrical energy by utilizing the methods utilized in a thermal power plant. To generate the power, long alloyed pipes that have higher resistivity against the corrosion and high temperatures and pressure are bored deep down into the earth’s crust to make the geothermal energy usable. When water is allowed to run into theses pipes, the geothermal energy makes the temperature of the water to shoot to a level where it converts into steam. Several geothermal power plants are working in the world to provide an uninterrupted power to different locations in the world. Geothermal grounds are parts where two tectonic plates meet. However, the energy can also be gathered without having the geothermal grounds by boring the pipes into the earth crust and marinating a heat exchange. Geothermal energy can be utilized for the majority of energy application like electricity generation, heating the water to be supplied to the homes and industry (DeGunther 2008). If considering the economic aspect of the energy source, it has enough potential to provide the energy to the world. It is type of green power and has a potential that cannot be counted but it has more than the potential to meet the all the energy requirements of the world (Mock, Tester & Wright 1997). In hotter regions it can also be utilized to maintain the temperature of home lower to certain degrees, as the temperature of the earth remains constant to 20-25o C. The operational cost associated to the geothermal power plants is comparatively low. While having so much advantages of the geothermal energy, there are some disadvantages of utilizing the geothermal energy. As the geothermal energy is made usable by digging deep down into the earth, the cost of the digging sometimes rises to an unmanageable way. Sometimes the expected amount of geothermal energy differs to the actual amount due to the lack of technology. Sometimes

Qualitative Research Problem and Design Essay Example | Topics and Well Written Essays - 1500 words

Qualitative Research Problem and Design - Essay Example The main methods for collecting qualitative data include individual interviews, focus groups, observations and action research. Many factors were considered in deciding the appropriate research methodology. A qualitative approach is effective in solving the problem in this case because it can create new theories. As the researcher attempts to understand the topic, he or she will have to interact with the participants. In addition, the researcher will have to study existing information about the topic. The practice may lead to the discovery of a new theory. Qualitative research is important when addressing a new phenomenon in the society or examining an important issue in the country (Jamshed, 2014). The possibility of discovering a new theory is important because it could result in a better understanding of student performance in mathematical subjects. In addition, qualitative analysis is likely to explain the relationship between things and demonstrate their effect in that situation. As a result, it contributes towards the development of a better understanding of the issue. Furthermore, the method is characterized by observation or reading information. The researcher is expected to respond to the insights learned from this approach through writing. Consequently, it contributes towards the growth of the existing body of knowledge about a topic. Qualitative research is based on a theoretical framework (Bendassoli, 2013). As a result, it shall be addressing an important issue in the society that is important for the well-being of the society. Addressing the high failure rates will enable the country to enhance its competitiveness. Furthermore, qualitative research is flexible. Instead of applying a rigidly defined framework, research method and data collection style, a flexible approach is important in developing a holistic understanding of an issue. The method involves the collection of data using observational
