Fossil Alternative Energy Sources
"Shifting Power" Since the beginning of industry humans have been in search of fuel to power machines and generate energy. Fossil fuels, such as crude oil and coal, discovered beneath the Earth"s surface were found to be an excellent source of fuel. These fossil fuels are burnt in order to generate the energy required to complete various tasks. However, we are now realizing the problems that are created by using fossil fuels to generate energy. These problems are so great that they will fo ... When the worlds supply of fossil fuels runs out there is no way to replenish this non-renewable resource and the world will be forced to find an alternative energy source. ... There are a number of renewable energy sources available to replace the problematic fossil fuels. "Renewable energy is a term used to describe energy that comes from sources which can be regenerated, and are, therefore, virtually unlimited" (Information 136). Sun, wind, water, vegetation, and heat from the Earth are all sources of renewable energy that can be used to generate useable energy. ... Renewables ... Wordcount: 1009 Pages: 4
The Availability of Geothermal and Renewable Source of Energy
I. Overview of Geothermal Energy Geothermal energy (from the Greek words geo [earth] and therme [heat], thus 'earth heat' energy) is a domestic energy resource with cost, reliability, and environmental advantages over conventional energy sources. Energy from this source comes from the renewable source of heat from deep in the Earth (diagram: A). Heat is brought up to near the surface by thermal conduction (diagram: B) and magma. This heat heats ground water to form hydrothermal resources ( ...

Alternative Sources of Fossil Fuels
Debate Topic: Fossil Fuels and Alternative Sources Most people in this world but especially in the U.S. think that fossil fuels are never ending. However, they are wrong and completely take them for granted. Therefore, if they do not try to use and find other sources for energy soon then fossil fuels will become extent. So I have taken it upon myself to look into other sources of energy and give my viewpoint about them. I looked into a couple alternative sources. First, technology and manu ...

The Utilization of Natural Energy Power Sources
A major transition in the modern energy age began in the 1970s, when the big nation"s industry started to grow up rapidly. The use of oil was very important and overnight, oil prices shot through the roof, and the trend of ever-cheaper, ever-more-plentiful energy sources were in need. Another player on the modern energy stage is nuclear power. An industry that didn't exist 40 years ago is now at a huge amount of production, producing 20 percent of the nation's electricity. Ironically, the in ... Another player on the modern energy stage is nuclear power. ... All the non-renewable energy resources have positive and negative affects to the nature.

Advantages of Using Solar Energy in Our Daily Lives
Solar Energy Solar energy is a very useful resource. Today 80% of the energy we use comes from fossil fuels and about 1% comes from solar energy. Fossil fuels are nonrenewable, that means that they are used up faster than they could be replaced. Also fossil fuels limited and cause pollution. They are the primary cause for air pollution that causes acid rain and global warming. The good thing about solar energy is that it is renewable because it is always replaced.

The World Conservation Strategy
INTRODUCTION A major challenge for mankind is an informed respose to unprecedented urban growth and the intelligent mangement of urban settlements. The 20th century began with perhaps a dozen cities of 1 million resisdents; it will end with several hundred cities of that size, including about 30 urban areas with population exceeding an arbitrary threshold of 8 million. Most of today's cities provide neither equilibrium with the enviornment nor stability for its citizens. Ever since the the c ...

California's Energy Deregulation Plan
Deregulation is the elimination of regulated rate tariffs on energy that is supplied. Deregulation ultimately spreads the risk of an energy crisis amongst multiple companies in a specific region then on one monopoly company. What it boils down to is, big money. Whether it is a natural gas company or a supplier of energy, the main goal is to make profit. Over the past years in California, it can be seen that many energy suppliers have been working to bring down the cost of making and providi ...

The Production of Greenhouse Gases Results To Global Warming
The Resolution Because the U.S. leads the world in the production of greenhouse gases (in particular, CO2) that are released into the atmosphere and contribute to the present climate change known as global warming, a plan of action is needed. The continuing sharp rise in the temperature of the air and of the oceans is a phenomenon that is presently causing serious problems world wide. This warming trend may, according to empirical research, lead to catastrophic, unprecedented destruction. S ... So, the way to resolve this most challenging of all global environmental issues, is through the implementation of a very comprehensible and pragmatic four-fold plan of attack: a) begin a massive phase-in of an energy conservation program (insulating houses, teaching people to use less energy); b) launch a major federally-mandated private/public partnership push towards the installation of solar-powered technologies in homes and businesses; c) as new and renewable energy sources come online, and energy conservation reduced the need for additional energy sources, begin the inevitable phase out o...

Benefits on Using Wind Mill Electric Source
In 1987, Renner and Renner wrote, "One year after the dramatic collapse of world oil prices, any initial enthusiasm about it has yielded to a more sober assessment of the inter- national energy market. The predicted benefits of the oil price drop have turned out to be grossly overstated: cheap, abundant oil is clearly not the solution to the world economy's deep structural problems. Moreover, oil does not seem likely to remain cheap and abundant. Last year's turmoil is part of a larger boom-bust ...
