Essays on Turbines

Abstract

The concentration of carbon dioxide has been abnormally increasing over the years. In the year 2016, its concentration exceeded the limitations, and has been considered as a dangerous situation. As a response to the increasing carbon dioxide content in the Earth’s atmosphere, different processes are being suggested in order to lower the concentration. Carbon Capture and Storage, or CCS, is one of these processes. Generally, there are three different phases of this process: the pre-combustion, the oxyfuel, and the post-combustion. These three phases have different processes in which the carbon dioxide content is being separated from the other ...

Introduction

The concept of sustainable development was first introduced in 1987 by the United Nations as part of the Report of the World Commission on Environment and Development, in which it was stated that sustainable development implies “meeting the needs of the present without compromising the ability of future generations to meet their own needs” (United Nations General Assembly, 1987). The World Conservation Strategy published in 1980 served as prelude to the conception of this notion, as the UN recognized the importance of minimizing the impact of human activity over the earth’s ecosystems and adopting models inclined towards sustainability ...

A Fossil fuel power station is a plant location where fossil fuels are burned producing electricity. Such fossil fuels include petroleum, natural gas, and coal. There are power plants which are designed for continuous operations for large scale purposes called central station fossil fuel power plants. Fossil fuel plants in many countries are used in the provision of electricity. They have machines for conversion of heat energy from combustion of fossil fuels into mechanical energy that operates an electrical generator producing electric currents (Camus et al. 154). The Samso Island is planning to exhaust the application of fossil fuels ...

Windmills have been widely used since thousands of years to pump water for agricultural purposes, propel ships and grind grains. As civilizations advanced, other convenient sources of energy replaced wind energy. Currently, fossil fuels that include coal, oil and natural gas fulfill the energy needs of nations across the world. These fuel sources are responsible for polluting the environment through the emission of hydrocarbons that cause global warming and various other environmental hazards. Also, these non-renewable energy sources are much limited and continue to deplete from the face of the earth. Therefore, wind energy that can be tapped conveniently ...

Since the industrial revolution – an era known for the peak of coal combustion to supply the energy requirements of mechanically evolving world – humankind has been relying on fossil fuels for the majority of energy. However, although the fossil fuel production is at the point of exhaustion, the world, in general, still is experiencing energy shortages, which is almost always associated with high energy prices (Pimentel 1). Furthermore, environmentalists advocate for cleaner energy source, such as the renewable energy sources, as an alternative to fossil fuel due to the fact that the fossil fuel itself, as well as the production ...

Wave and Wind Power Generation

Wind Physics Basics Wind is atmospheric air which is in motion Energy Source The earth surface absorbs solar radiation differently. Some parts absorb more radiation than other. This creates pressure zones. As a result of pressure, air moves from high-pressure zones to low-pressure zones. This causes atmospheric air motion known as wind. Wind is a renewable source of energy. It is constantly available free of charge (Bhattacharyya, 2011).

Spatial scales

Atmospheric air motion can be categorized depending in terms of spatial scale. Four spatial scales identified include planetary scale, synoptic scale, mesoscale, and microscale. There are various types of spatial scales ...

According to John Arend, Mike Benkert, Audrey deFilippis and Saretta Tillmaand, when the Commerzbank building opened its doors in 1997, the “53-story” edifice became the one of the “tallest” buildings located in Europe (1). Nevertheless, the edifice’s distinctiveness did not come from its height, but, rather, it came from the way in which it combined “form, inventiveness, and technical expertise” (Arend, Benkert, deFilippis, & Tillmaand 1). The design and construction of the Commerzbank saw the “[b]reaking away from the American model of deep-planned, air-conditioned structures” that have a “central service core” (Arend, Benkert, deFilippis, & ...

Introduction

Energy is a key driver of any nation’s economy. The extent to which it contributes to the performance of all activities surrounding the human life is beyond measure. This is because energy contributes almost fully to the economic development of the economy. In its physical form, energy is classified either as renewable or non-renewable. Renewable energy forms the green energy that can be reused again and is less toxic to the environment. On the other hand, non-renewable energy is exploited once it’s used and mostly pollutes the environment. All this energy forms can be either used directly ...

The standards of any factory setting need to maintain and comply with specific ethical standards according to the laws and regulations that are set for manufacturing. However, that is not always possible, especially if the factory is based in an area that does not require certain common health standards. Workplace ethics need to hold everyone accountable for the workers as well as the product. A factory should put the workers first and keep them in mind to set and maintain a standard that will keep everyone safe. End customer safety is a large concern for most manufacturing businesses. Basically, ...

Stand-alone Power Supply and Heating Systems

An individual’s carbon footprint is mainly decided by energy consumed to run various household appliances and energy used for home heating. Electric power supplied to grid-connected households is mostly derived from fossil fuels, and thus leads to greenhouse gas (GHG) emissions. However, homes in remote areas cannot afford grid power supply, and they use renewable natural sources available to them such as solar power, wind power, hydroelectric power or geothermal energy. Even, houses that can be connected to the power grid can opt for stand-alone power systems to reduce GHG emissions. Most common form of off-grid power system ...
