Essays on Wind Power

The world is realizing the impacts of global warming and energy crisis and moving towards solutions that can help them to overcome these issues. The Pertamina Energy Tower is such a project that is in the construction process in Jakarta, Indonesia and the completion date of the project is in 2020. The renowned American architectural firm Skidmore, Owings, and Merril LLP (SOM) is involved in the project. The total area is 495,000 square meters with a site area of 57,512-meter square. The building will have 99 floors with the height of over 500 meters. The building will ...

On a daily basis, I use energy to watch television, listen to music, cook, take a hot shower, and warm the house. All these activities involve the use of energy, thereby making it a fundamental part of our daily lives. The sources of energy that I use include electricity, solar power, and natural gas. Renewable energy encompasses energy that is generated from resources that can be replenished naturally such as rain, sun, wind and geothermal heat (Hansen, 2014). Renewable energy sources provide energy that can be used in the generation of electricity, water and air cooling or heating, home ...

Executive Summary SunEdison is a renewable energy company. Its revenue comes from semiconductor wafer manufacturing, solar energy business and TerraForm Power (wind power and global business). The company has recently filed for bankruptcy due to poor operational performance and its inability to serve its $11 billion debt. Luckily for the company, first and second lien holders have provided the required capital to continue operation. Overall, the renewable energy market is growing at a very high rate. However, due ...

Executive Project Summary – Malawi Wind Farm

Market Summary Malawi has an electricity production of 2,180 MWh and a consumption of 2,027 MWh. The 95% of the electricity generation comes from hydroelectric sources giving to the high country risks of supply shortages in adverse weather conditions when the water level of the hydroelectric plants is below the technical specifications of the turbines. The country has no other important source of energy having the country the necessity to develop new energy sources different to the hydroelectricity. The surroundings of the Malawi Lake develop winds over the 10 m/s average per year, opening the opportunity to ...

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 ...

Briefing: Climate Change

Global warming is an environmental issue which effects every single one of us. The past 50 years has seen the fastest increase in global temperatures in recorded history; since the year 2000, 15 out of 16 of the hottest days since temperatures have been recorded happened ("Global Warming 101", n.p.). The scientific explanation for global warming is that carbon dioxide (CO2), as well as other pollutants, get into the atmosphere and trap sunlight and solar radiation, causing an increase in global temperatures ("Global Warming 101", n.p.). The two major sources of CO2 are coal-burning for energy and emissions from ...

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 ...

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 ...

In a nuclear power plant, fission produces energy in the Nuclear Steam Supply System that turns water into steam. The steam turns turbines connected to an electricity generator as shown in figure 1 in the index attached (Farris). Electricity produced in this form has both pros and cons

Advantages

Maehlum noted that although the initial cost of a nuclear plant is high, the source of energy to run it (fission of uranium) is low. The only significant cost is the maintenance of the facility, enriching the uranium, and disposing of the waste. Moreover, nuclear energy has little pollution effect on ...

Electricity still remains the most important energy source in the present world driven by information and communications. There are quite a number of energy sources but under two broad categories - renewable and non-renewable energy source. The non-renewable energy sources include coal, gas, crude oil etc. The renewable energy sources include solar energy, wind energy etc. Non-renewable energy sources are burnt and cannot be replenished but renewable sources are not diminished when they are used. One down side of non-renewable energy sources which have been widely used in the past centuries up till now is the air pollution they ...

Global warming is the rise in average global temperatures. The rise in global temperatures is occasioned by the emission of greenhouses gases such as carbon dioxide, carbon monoxide, methane, and nitrogen oxides. The gases are released from industrial process that combust fossil fuels such as diesel, coal, and petrol. Such processes include generation of electrical energy in thermal power stations, burning of coal in industrial boilers, and combustion of fossil fuels in internal combustion engines. When these greenhouse gases are emitted, they rise to upper levels of the atmosphere and form a layer that blankets the earth. This layer ...

Abstract

Montreal is concentrating on making the city appealing to the general public and by extension the entire globe. Considering the possibility of wider and heated sidewalks alongside fewer cars and more trees, Montreal has decided to launch the future of Saint Catherine Street. The street being the most important in the city requires innovation, flexibility and audacity in an effort to offer a description of the dynamic and greener look on the streets. The street is the largest and this means it requires more attention than any other street in the country. There is a dire need for infrastructure ...

Role of GIS in Promoting a More Sustainable Future in Energy: A case study of theStädteregion Aachen in Germany In the last decades, the world has experienced unprecedented population growth. Populations in the cities have doubled up with more than 74% of the country’s population live inside urban centres in developed countries. In developing countries, approximately 44% of the population are living in urban settings. With the influx of people in urban areas, there has been an increase in the consumption of energy. With increased use of fossil fuel, there has been constant pollution by gases like ...
