Wave Kinetics and Tidal Energy as an Alternative Research Paper

Wave Kinetics and Tidal Energy as an Alternative - Research Paper Example Wind has also energy stored in it, which can be transformed to a usable form by utilizing windmills or wind generators. Similarly sun provides us both light energy and thermal energy. Both of the solar energy types can be transformed to other energy forms to be utilized in a usable manner. Running water has also an energy stored in it, which is a hydrodynamic energy, which is due to the mass of the water and the gravitation of the earth. In the similar manner, biomass provides the biogas, which has a high concentration of methane in it which can be burnt to attain thermal energy. Energy can also be attained from high and low tides. The main concern of the modern world is the emissions of green house gasses that are the result to burning of the fossil fuels like coal, furnace oil, etc to attain the high amounts of thermal and kinetic energy. Fossil fuel is considered to be a conventional resource to attain energy and modern world is looking forward to utilize the alternative resources like wind, tidal, solar geothermal, hydro, etc. The utilization of these alternative resources ensures low or no carbon and green house gasses emissions and if the energy is utilized for the generation of power, low operational costs are also ensured. In this research, my major focus is to discuss the environmental and economic aspects of utilizing the wave kinetic and tidal energy for the generation of power (Pikeresearch 2011). The other matter that should be discussed is the potential of wave kinetic and tidal energy to meet the demand for the energy and is the resources have more or less potential or low capital costs than harvesting other alternative energy. The higher the capital cost (effective cost to establish an energy harvesting system), the higher will be the unit price of the power. Wave kinetic or a hydrokinetic energy is the energy that is attained by the force of waves that have a deep impact on the shores. This type of energy has the enough potential to generate po wer on the shores, near shores and off shores. Moving water has a crushing power that could be utilized to generate power. It will be a difficult task for a swimmer to swim opposing the waves. The power of moving water can be seen in a hydro power plant that is able to generate the power that could fulfill the requirements of more than one city. The wave kinetic energy is an alternate type of energy that has enough potential to generate power that could replace many coal fired power plants. Tidal energy can also be utilized as an alternate energy resource to generate power. Running water is utilized to produce tides that are essentially utilized to generate power. Water in the form of tides has a hydrodynamic energy. The tidal energy can be collected from rivers, where turbines that are able to transform the kinetic energy of the water into electrical energy. The tidal generator is similar to a wind turbine generator but the major difference is that the tidal energy generators are l ie under the surface of water to capture the hydrodynamic energy of water. Tidal energy can also be attained from oceans, as tides also influence the ocean water. The system utilizes a separation with an empty space at lower end to install a tidal generator, between the ocean and basin. At high tide the level of water at the ocean side rises and pressure of water rises towards the basin side. The pressure of water enables the tidal generator to generate several kilos to mega watts of energy.

The Review - Essay Example In 1970, it accounted for 6.4% of the US capital stock and in 1988, this figure stood at 19.8% (Roach, 1988). The increase has been more pronounced in the manufacturing sector. In this sector, it grew from 1.6% in 1970 to 10.6% in 1988 (Roach, 1988). Extensive computerization and use of information technologies initiates an interest in knoing why many organizations or institutions have adopted these technologies. Most organizations are profit oriented and this means they not only focus positive returns but also how to obtain good financial rewards. Having this focus, many organizations always seek ways of limiting their costs of production while increasing production at the same time. This paper gives a literature review on how computerization and the use of IT increase worker productivity and reduces costs of production for many organizations, the focus being the manufacturing sector. Computerization and the use of IT in the workplace The term information technology can be defined a s the acquisition, processing, storage and distribution of numerical, textual, vocal and pictorial information through a combination of computing and telecommunications (Allen and Morton 1994). It therefore encompasses computer software, computer hardware, information systems, processes, data constructs, programming languages. Machines under IT domain render any data or information in visual format via multimedia distribution. Computerisation or computing refers to the action of utilising and improving or advancing computer software and computer hardware according to Agrawal and Symes (1994). In simple terms, computerisation is any goal-oriented activity benefiting from computer hardware and software. In the case of manufacturing industry, machines are run by computers that manipulate data according to a set of programs or instructions. General examples of utilisation of computerisation and IT manufacturing industries include networking, data management, information databases, and m ost importantly automation of machines. Like in many organisations, labour productivity in manufacturing industries is calculated by dividing the level of output by the specific level of labour input. Worker productivity is one of the important elements in determining the efficiency of an industry. Impact of computers and ITs on worker productivity and costs of production For many manufacturing industries, information technologies have continuously influenced work and changed the way it is done. One of the main impact of computerization and the use of technologies is the automation of machines. This has allowed manufacturing industries to assign repetitive and non-core tasks to machines while allowing employees to specialize in performing non-repetitive, complex and core duties of the organization. In this case, employees are able to fully utilize their skills and talents in the tasks assigned to them. This means that they offer their best and can handle more work in the area assign ed to them. Before the introduction of computers and IT in the workplace, employees would carry out every type of production activity including the most tedious and repetitive tasks. Due to the distances between the physical places of production assigned to these tasks, workers wasted a lot of time moving from one part of the industry to the other. As stated above, automated machines have taken over some of the repetitive and tedious tasks and
