Essays on Renewable Energy

The development of solar energy is based on a use of solar radiation for generation energy. Solar energy is the kinetic energy of the radiation (mainly light) formed by reactions in the solar interior. As its stocks are almost inexhaustible (astronomers counted that the Sun will “burn” some more millions of years), solar energy belongs to a renewable source of energy. In natural ecosystems, only a small part of the solar energy is absorbed by chlorophyll that contains in the leaves of plants and is used for photosynthesis, namely for the formation of organic matter from carbon dioxide and ...

Types of Centrifugal Pumps

Centrifugal pumps consist of impellers and volutes and turn electrical energy into mechanical energy.

Third Grade Students

For teaching third grade students, I would use games in order to introduce the concept of renewable energy. Teaching the concept of renewable energy to most people could be a hard task especially when individuals have little knowledge about its importance. For third grade students, they should have the idea about the sources of stored energy such as fuel, batteries and food (Aquarium of the Pacific 1). They also have the idea about the concept of converting energy into many forms. For example, energy from the sun or solar energy could be converted into stored energy using photosynthesis. The ...

1.0 Introduction The rate at which the availability of natural fuel resources are getting depleted is higher than the consumption (Huang, Krock and Oney 158). This calls for clean energy sources such as Ocean Thermal Energy Conversion (OTEC). Ocean Thermal Energy Conversion whose short form is abbreviated as OTEC is essentially based on the utilization of temperature differences (Plocek, Laboy and Marti 1). In particular, the difference of incumbent temperature between the deep and the shallow areas of water become the source of electrical energy. This electricity is produced when the temperature difference is used to run a heat ...

Introduction

One of the most important things, if not the most important one, that society needs today is energy. Energy comes in many form and moist literatures focusing on this topic would agree that among all the possible sources of energy, oil comes as the most heavily demanded, and hence the most important. In fact, one may argue that the geopolitical movements and decisions that have been made in the past half a century have been motivated by access to this important energy-related commodity. There are many possible sources of energy but even though oil just comes as one of ...

Solar power is a renewable source of energy, conversed of sunlight into electricity, directly using photovoltaics or indirectly using concentrated solar power. Photovoltaics were used to power small and medium applications, from watch and calculator to off-grid homes. This is an inexpensive source of electrical energy, and according to a new Fraunhofer report, solar power in sunny regions of the world is going to be cheaper from gas or coal. For several years worldwide growth of solar photovoltaics (further PV) raised in many countries and regions all over the world, including Australia, Canada, South Africa, and Thailand.

Reflective Statement

Taking the course has brought me to a deeper understanding and appreciation of what nature has given us freely and a realization of what contributions I make in the process of destroying her. It is fascinating to realize that everything we do has an effect on either its preservation or tearing down. This makes our attitude or actions towards her very important and critical because if she is destroyed, its inhabitants will also be destroyed along with her.

The last three months has been like going through an evolution. An evolution of knowing what my lifestyle is contributing to the ...

I. Introduction Human activities are causing the world to warm and the global average temperature is predicted to increase by 1.8-4.0C (3.2-7.2F) by the end of the century. (Griffin, 2009) These numbers might not seem that large but when you factor in the rate at which they are increasing, it almost becomes obvious that human contributed greenhouse gases are a huge contributing factor. Since the climate will continue to change for natural and humans activity reasons, it critical to understand the adaptations humans need to do as soon as possible. For certain, if oil production and oil consumption ...

Energy is essential in all processes that make life simple in the society. It is also important in movement, growth, and development in living things. Therefore, it is important that the society comes up with feasible and efficient ways of producing energy. Research on energy is based on ‘sound science’ which is a common phrase used by government agencies and corporations to mean scientific research aimed at proving a claim (Morrone & Lohner, 2002). Rathore & Panwar, (2007) also claim that sound science means insisting on higher evidences before an action to protect environment or public health is done.

Therefore, in considering ...

Electricity has been the most important part of mankind. Since the discovery of electromagnetic induction by Michael Faraday in 1831, it came a long way in helping every activity of man. And with this, demand for electricity has gone up in recent years. A need for larger plants to produce electricity is necessary to sustain this demand. However to obtain electricity, we must harvest this from energy sources. Currently, fossil fuels have been the primary source of energy, however these are considered non-renewable and fossil fuels are being consumed rapidly in recent years. With this scare resources depleting, different sources ...

There are literally a lot of elements that hold at least a certain level of relevance in the geochemical and bio-geochemical industry or cycling. One important thing to know about these elements is that most, if not all, of them are non-renewable. Most are stored in ores found underneath the earth’s surface. What makes the process of obtaining those elements more problematic is the fact that they need to be mined, extracted, and processed before they can be deemed usable for industrial and consumerism-related purposes. These ores are abundant and this is why at this point, they are practically inexhaustible. ...

Climate change is one of the biggest challenges facing humans. Individual’s lifestyles have developed to such an extent in developed countries that people continue to drain the earth of fossil fuels used to sustain humans. The result is that global warming is happening as a result of natural but predominantly human activities that release carbon emissions into the atmosphere. Measuring the best forms of energy to counteract this depends on a number of technological, economic and societal variables. It also requires the efforts of government to use command and control along with economic incentives to the highest potential for each ...

Abstract

The current and ongoing debate around renewable and alternative energy sources has led to the scientific examination of such energy sources. The result has been the continuous development of two energy sources, the wind and solar energy. The two have been subject to research into the ways through which they can be utilised to obtain the best results from them. Hence, the question of viability has arisen. Australia is one country where the impact of climate change is been felt. Thus, wind and solar energy could offer the best option for reduction of these effects. As a result, ...

Whether Renewable Energies Can Make a Major Contribution to the Global Energy Budget and Further Policies Needed To Achieve This.

The question of whether investment in renewable energy production will help reduce the global expenditure on energy production should be viewed on economic, social, and environmental perspective. Economically, expenditure on renewable energy production is currently higher than energy production from most non-renewable sources (Wengenmayr and Bührke, 2011). This explains why subsidies are often being offered to promote production from renewable sources. A study by the institute of physics at the University of Oldenburg found that the ...

In the United States, the forms of energy used have improved over time. It has been influenced by advances in technology, discoveries of energy resources, prices of energy, social demands and other aspects. The only thing that is constant is the increased of the amount of energy that is being used over time.

In the 1700's Americans used burned wood as a fuel. Wood was used for heating space and power generation since it was uncomplicated to get, portable and can be used as needed. In the early 1800's coal was used and it supplied more heat than wood. ...

In physics, energy is loosely defined as the ability to do work. This definition often takes into assumption that energy can’t be directly observed but only its effects can be observed. Therefore, energy can only be defined by what it does not what it is. From this definition, it is clear that energy is used to do some work. From the definition of work, it is also clear that energy is the ability to exert a certain force on a body or particle of mass. Sources of energy can be broadly divided into two categories. The major categories ...

Introduction

The concept of sustainable development within the industrialized nations and the increased worries caused by global warming, has led to a global interest in the need to come up with better ways in which building construction projects within the urban settings can be done in such a manner as to promote sustainability of our environment as opposed to the rather “business as usual” myopic concept in building projects. This will ensure that this generation meets its own needs without negatively interfering with the ability of the coming generation to meet their own needs. In most scenarios, most building projects can ...

United States of America has used oil as its main source of energy for a long time but, it can emulate the Simso community project. This because, however, they have ready access to oil in the state, the oil is a major source of global warming that leads to climate change. The Simso community initially used electricity that was coming mainly from the mainland that was passing through a cable and generation coming from coal. This affects the atmosphere as carbon dioxide is generated through the process in tones. For example, each sassing into the atmosphere generates almost eleven tones on an ...

The United States of America is said to be the largest dependent on fossil fuels by a research conducted by southeast Missouri state university’s Robert Polack. He found out that the US uses fossil fuels in almost each and every sector from food, consumer goods, transportation, energy procurement itself to heating. Basically, our economy runs on fossil fuels, but question is what if the world runs out of fossil fuels in the near future what are we going to do? The answer to this perplexing question is to venture into renewable sources of energy, which will relieve us the ...

Introduction

Saudi Arabia being the world’s largest oil producer has stipulated plans to switch by a 100 percent to renewable sources of energy as well as low carbon forms of energy. However, this process is likely to take decades as observers and critics are skeptical as to whether the whole process is anything more than a window dressing. The rate off energy consumption in Saudi Arabia has risen rapidly faster than any other Middle East country (Bahgat, p. 566). According to statistics, the total electricity consumption in the country exceeds over 200 billion-kilo watts every year and the amount is expected ...

Introduction

Currently, coal-fired power plants account for more than 80% of carbon dioxide emissions in the electric power industry of the United States and 33% of all the carbon dioxide emissions in the United States. Consequently, reducing carbon dioxide emissions that come from the coal plants is the focus of most proposals that intend to cut on the greenhouse gas emission. The options to do this include capturing and sequestering carbon dioxide that emitted by the coal power plants, replacing the coal power plants with the low or zero carbon dioxide sources of power like the nuclear and wind energy.
