Energy and Its Sources Essay

… Even though there are several environmental problems associated with the increased use of fossil fuels, they continue to be popular. They are attractive because they are available and apparently inexpensive making them to be considered as marvelous energy sources. Moreover, fossil fuels are attractive because people have learnt to use them very effectively as they entail relatively simple technology. Actually, they are apparently easy to use because they only require a simple direct combustion in order to generate energy.

Alternatives to Fossil Fuels:

Overview of Renewable Energy Alternatives

A general definition of alternative energy provided by Kramarae and Spender (2000) states that this term includes systems such as hydroelectric power plants, wind generators, solar power, and biomass (in the form of wood fuel, crop, municipal and industrial waste, as well as animal manure). In many ways, these alternative energy sources are certainly not new, but have rather been used by…. [read more]

Why Clean Renewable Energy Is Imperative to Our Future Thesis

… Renewable Energy

The United States is facing a seminal moment in terms of energy policy. Since 1970, the percentage of our oil that has been imported has increased from 24% to 70% (Pickens, 2008). While some of this oil comes from close allies such as Canada, Mexico, and the United Kingdom the majority of it comes from producers with whom we have a more adversarial relationship such as Venezuela and the Middle East. This represents a serious national security issue because we have become dependent on countries that, if not our enemies, are certainly not our friends.

Compounding the problem of foreign oil dependence is the fact that oil is not a renewable resource. Some observers believe we reached peak oil in 2005 (Pickens, 2008).…. [read more]

Energy in the United States Term Paper

… It should be noted that if more is invested in the erection of a windmill or a generator and the interest rates that are being charged for the manufacturing equipment then the consumer of this energy will also have to bear a part of this cost. According to a study it was discovered that if the finance of the wind plants are made at the same level as that of gas plants, then the cost of these plants would decrease by almost 40%. Fortunately enough, the cost of wind energy is proportional to the facilities being built.

However, investments are being made to find out and exploit other sources of power and ways to make them viable. These sources include wave energy, geothermal and biomass.…. [read more]

Alternative Energy Sources Concerns Essay

… A dam that is constructed across the river acts as a reservoir where water is stored. This type of hydropower plant is known as Impoundment hydropower. Water that is released from the reservoir flows through a turbine that spins it. This spinning action activates a generator that produces electricity.

The major components of hydroelectric dam are the dam, penstock, turbine, generator, transformer, and transmission lines (Alternative Energy Resources, 2008). Penstock is just a pipeline that conveys water that is under pressure from the reservoir to the turbines. Turbines are normally turned on by the forces of the fast moving water that pushes against the blades. Turbines convert kinetic energy into mechanical energy. The transformer converts electricity from the generator to usable voltage levels. Transmission lines…. [read more]

However this technology sometimes does not work under specific circumstances. Norway, for example, ranked the sixth from the top hydroelectric generating countries in 1998. The country depends much on the hydroelectric stations that provide it economical source of electricity for its people. Once the government realized that they had trouble during the dry year, the electricity cost had increased to 400%. The prolonged dry season had left the dams empty that only limited sources of stored energy left, causing extreme hikes on electricity cost. It might cost 2-3 times…. [read more]

… Currently, the vast majority of wind turbine capacity is located in only a few countries, including Germany, Spain, Japan, Italy, and the United States.


Almost without exception, all living matter derives most of its energy from the sun and stores it through carbon fixation. Traditional methods of converting solar energy into a useable form include the burning of firewood, straw, and animal dung for cooking and warmth, which still represents a major energy sourced in undeveloped countries. In developed countries the sources of biomass include agricultural and forestry residues, and municipal waste. Although still an important source of energy in developed economies, biomass provides a much smaller share of the energy consumed when compared to third world economies. The global energy contribution of biomass…. [read more]

Renewable Energy Development Term Paper

… Biomass, which uses forest and agricultural residues, is used around the world, and the use geothermal energy is growing slowly. All of these forms of energy need to be fully explored to gain more usage and recognition.

Another viable renewable energy source is the fuel cell, which has been around since 1829, longer than the internal combustion engine (Flavin & Dunn, 1999, p. 167). Fuel cells combine hydrogen and oxygen to provide water vapor and electricity. They can be extremely efficient, and have been used in the space program since the 1960s. However, they still have not come into commercial use, mainly because of the difficulty of using the hydrogen, which is highly volatile and expensive. However, "Researchers are now testing various catalysts that, when…. [read more]

Physical Science: Energy Essay

… In hydroelectric power plants, a mass of water flows through hydraulic turbines, converting the water's potential energy into kinetic energy within the turbines and driving electric generators, thereby creating electrical energy that can be stored and used. Hydroelectric power is a more attractive than fossil fuels because it is renewable, non-polluting and highly efficient, as large turbines can capture up to 90% of the water stream's power. Hydroelectric power does have significant disadvantages because it can disrupt the environment's normal ecology by changing the water's natural flow and using a considerable amount of surrounding land.

Wind power, which is another form of solar power because wind is created by solar radiation, uses turbine-like wind generators: wind propels the generators, which convert the wind's kinetic energy…. [read more]

Solar Energy Essay

… Solar Energy

As typical hydrocarbon materials are significantly challenging and costly to draw out, energy businesses need to alter their approach in order to fulfil the needs of an expanding populace progressively depending on power. Renewable resource has actually become the focus for numerous energy businesses as they look to a 'greener' future. Whether this enhancing dedication has actually come from an authentic will to do much better or from the altering needs of stakeholders is one argument that continues still. That aside, the numbers promote themselves. Financial investment in renewable resource has actually enhanced five-fold from 1990. The solar market is a quickly expanding sector within renewables as technological advances recently have actually made solar cells more efficient and far less costly to produce…. [read more]

Sources of Community Energy Term Paper

… That can be an issue, but it is a small one when compared to other energy sources that require nearly complete destruction of the natural environment in order to be useful (Lovins, 2011; Makower, Pernick, & Wilder, 2009). Additionally, the sources of power that Willows is using will not be used up by their consumption, so there is no concern that the community will run out of power. It will not be possible to run out of sunshine or out of wind, and running out of water from major rivers in the area would be highly unlikely. If SRP did have to switch away from hydroelectric power at a later date, the community could transfer over to solar and wind only, by building more wind…. [read more]

Capturing and Storing Energy Research Proposal

… "Single small turbines, below 100 kilowatts, are used for homes, telecommunications dishes, or water pumping. Small turbines are sometimes used in connection with diesel generators, batteries, and photovoltaic systems. These systems are called hybrid wind systems and are typically used in remote, off-grid locations, where a connection to the utility grid is not available" (U.S. Department of Energy, 2014). The research questions associated with wind power focus largely on the fact that wind flow patterns and speeds vary tremendously across the globe. Is wind power a viable solution, or partial solution, in areas without traditional high winds? Do offshore and on land wind turbines produce similar results? Is there a practical way to store wind energy or does the energy need to be used once…. [read more]

Globalization and the Demand for Energy in the 21st Century Term Paper

… Globalization and Energy Demands in the 21st Century

According to a May 2004 report from Deloitte Research, supplying enough energy on a reliable basis at prices that will not cripple the global economic growth has become a challenge with consequences that are difficult to predict (Globalization pp). Although this will provide new opportunities for oil and gas companies, pipelines, generators, utilities and others in the energy business, it also carries serious risks (Globalization pp). The demand for energy is growing, not only in the developed economies of Europe, Japan and North American, but in developing countries as well (Globalization pp). In fact, the fastest demand growth is in China and other emerging markets, thus from one side of the globe to the other, societies are…. [read more]

Positive Effects of Green Energy Essay

… A home can use them and end up giving electricity back to the electric company in many cases, but putting up enough solar panels to power a standard-sized home can cost thousands or even tens of thousands of dollars. It is a long-term investment that does not always pay off, because it takes many years of reduced or eliminated electric bills for the solar panels to ever pay for themselves (Marion & Wilcox, 1995). For some people, that never happens. People who do not get their money back may not mind, because it might not be all about the money. They are living "off the grid" in some cases, and they are taking it easy on the planet. Those things may be far more important…. [read more]

Energy in China and the US Research Paper

… China's energy sources reflect their local resources and their economic status, with the country seeing significant changes over the past few years, with high levels of government support for renewable and green energy. In 2012 66% of all energy used, oil 20%, hydroelectric power 8%, natural gas 5%, nuclear power and other renewables at less than 1% (EIA, 2016b). This has resulted in recent shifts; in 2015 the country increased renewables, installing an additional capacity of 32.5 GW of wind power and 18.3 GW of solar power generation (Energy Post, 2016). Nuclear power generation and use also increased by 30%, gas has increased by 3.3% and coal consumption has fallen by 3.7% now accounting for approximately 64% of all energy consumed in China; all occurring….

Renewable Energy 2nd Generation Biofuels Essay

… Renewable Energy

Biofuels are becoming an important component of renewable energy initiatives. While first generation ethanol production, mainly from corn in the U.S., has created negative externalities by repurposing agricultural output for energy usage, second generation biofuels have the potential to achieve similar energy output levels without altering agricultural land use patterns. As with any new technology, there are a number of precursors for its success. This paper will analyze those precursors as part of making the case for developing second-generation biofuels. It is hypothesized that second generation biofuels represent a strong investment opportunity, but the timing of that opportunity is dependent on both fossil fuel prices and on the ability to develop these biofuels without creating negative externalities in food production.

Implementation of Solar Power Research Paper

… Government Policies and Solar Power Systems

Government regulations and policies affect renewable power generation a great deal, as is revealed through a brief review of the history of governmental policy in regards to power generation. Federal, state, and local governments support solar power creation, progress and improvement through a broad assortment of strategy and regulatory instruments. As the cost of solar power creation has fallen during administrative incentivization, the regulatory expenses have increased. Some modification is desirable in the permitting procedure for this innovative equipment. The prospect of government fiscal incentivization is reliant on both the financial system and the political state of affairs.

Any explanation of solar power in the current market must begin with an exploration of the traditional generation of electricity. Schmidt…. [read more]

Environmental Issues and Nuclear Power Essay

… Environmental Issues and Nuclear Power

The consensus among scientists is that there is an ongoing environmental crisis a large part of which is associated with Global Warming (Poiman & Poiman, 2007). Another very significant part of the environmental issues facing our descendants as well as many of us, particularly in the United States is the problem of dependence on fossil fuels, such as oil, other petroleum products, and coal for energy. Certainly, the continued burning of oil and coal contributes substantially to Global Warming, but its detrimental effects are much more complex then that. Ideological tension and conflict, mainly on the part of Muslim extremists in the Middle East and Africa, greatly magnify the real cost of continued Western dependence on OPEC oil (Larsen, 2007).….

Pros and Cons of Solar Power

The United States currently depends overwhelmingly on coal, oil, and natural gas -- fossil fuels -- to supply its energy needs, which are massive. All of these fuels are not found in quantities that allow them to continue forever. They are nonrenewable. When they are gone, they are gone. It would take thousands if not millions of years for nature to reproduce them.

And for man to re-invent them in some artificial form would be too costly or it would cause irreparable environmental damage. However, renewable energy -- wind, solar, the tides, geothermal -- are continuously available from mother nature and will not be depleted ever.
