1. Alternative Energy
Are alternative energy sources the answer to ending human dependence on oil? September 24, 2012 Are alternative energy sources the answer to
ending human dependence on oil? Right now there is no one substitute for oil because we use it for a variety of things. We can use alternative
sources in areas to preserve or conserve our usage of oil. We use to use wood for fires and light. Then in the industrial revolution we began to use
coal. "Coal can provide much more energy over longer periods than wood or any other biomass product. Forests were also diminishing in many
regions because they were being consumed for fuel." (Eric McLamb). Edwin L. Drake drilled the world's first oil well in 1859 and launched the
petroleum industry. Bach then...show more content...
Maybe if they did a payment schedule on buying them rather than leasing it would attract even more people. Solar panels take up a lot of space
but they don't need to. You can put PV on your roof, the roof of your business, garages, covered bridges and tunnels. If you decided not to do any
of these the entire U.S. could be powered by using 4/10 of one percent of U.S. land (http://www.geokingsolar.com/faq_pv.html#Q50). This is
mainly because the technology has improved so much. There is still the issue of places that don't get a lot of sunlight, such as Alaska where it is
dark half of the year. I'm sure in the years to come we will find a way to either use our existing power lines or create new ones to allow us to power
areas that get less light with those that get more sunlight. Wind turbines require a lot of space and a lot of turbines to produce power but who says
they have to be on land. Horns Rev 1 located in Denmark is one of the world's largest off shore wind farms. "Biologists compared a recent survey of
fish at Horns Rev 1 with an 8–year–old study conducted prior to construction of the 160–megawatt installation, and found most to be thriving. Some
species actually increased in number." (Bob Petz). They have found that the turbines steadied by rocks create a reef like haven and have created a
more diverse biome. Wind turbines also require wind which some areas don't get a lot of. You need

2. Alternative Energy Essay
Every day, many fossil fuel consuming contraptions spew out gases that pollute the environment. However, when the fuel supplies for these devices
run out, they will grind to a halt. To prevent this, the United States needs to find an alternative to unstable and polluting energy sources before it's too
late (Rouge). It also needs to advance in technological status in order to stay above advancing third–world countries, and retain its current level of
hegemony (Glaser). Space Based Solar Power Satellites, which are satellites that collect the sun's energy and beam it down to the Earth, solve for all
these concerns (Rouge). Thus, the United States Federal Government should provide grants for research, development, and implementation of Space

In other words, even though other energy sources could solve the energy crisis, none boast the advantages and flexibility that Space Based Solar
Power can provide. For example, Solar Power Satellites are extremely useful to the military, as they are capable of beaming energy down to any
location on the world, and are able to support military operations all over the world. People may argue that the United States does not have the
technology to develop Space Based Solar Power, and that it will never get into space (Mankins). However, the technology required is already
available. According to Rouge, "Space Based Solar Power is a complex engineering challenge, but [it] requires no fundamental scientific
breakthroughs or new physics to become a reality (Rouge)." If the United States is to prepare for a future energy crisis, it must act now and begin
development on Space Based Solar Power.
The United States is currently the most powerful nation in the world due to its economy and technological dominance, but may not stay in that position
for much longer if the United States doesn't substantially increase the money being spent for research and development of new technologies. Every
year, more and more countries pour money into research, and they begin to develop technology that rivals that of the United States, which reduces the
United States' technological

3. Alternative Energy Resources Essays
The energy that is used today comes from fossil fuels, which is a nonrenewable limited resource that will eventually be used up. Alternative energy
sources such as solar, hydroelectric, geothermal and wind energies can be used, to conserve the planets limited natural resources. Alternative energy
is the use of another energy without the burning of fossil fuels and break up on atoms. Solar energy can be used to operate cars and provide
electricity for homes and businesses. Hydroelectric energy can be used to provide electric power to small towns and cities. Geothermal energy can be
used to heat buildings or water and to power turbines to make power. Wind energy can be used to pump water and generate electricity. Solar energy is of

The most common type of hydroelectric power comes from using a dam on a river or lake. Water is discharged from the reservoir, which spins the
turbine, which activates a generator to get electricity. Hydroelectric power does not require a large dam. Some hydroelectric power plants just use a
small canal to channel the river water through a turbine. (Union of Concerned Scientists) Third, geothermal energy is heat from the earth that is used
directly as hot water or steam, or used to produce electricity. Geothermal energy is contained in underground reservoirs of steam, hot water, hot dry
rocks and hot spots. Geothermal hot spots are volcanic features which are found all around the world. Basically a hotspot is an area of reduced
thickness in the mantle which transmits excess internal heat from the interior of the earth to the outer crust. These hot spots are well known for their
unique effects on the surface, such as the volcanic islands of Hawaii, the mineral deposits and geysers in Yellowstone National Park, or the hot springs
in Iceland. These geothermal hot spots can easily be used to generate electricity. (Alternative Energy Sources)
They are used at electric generating facilities, hot water or steam extracted from geothermal reservoirs in the Earth's crust is supplied to steam turbines
at electric utilities that drive generators to produce electricity. Moderate to low

4. Alternative Energy Essay
A topic that has been in discussion throughout the years was the use of alternative energy. Alternative Energy is being increasingly used due to "The
threat of global warming." (Tom Udall, "Clean Energy," par. 3). The result of the burning of fossil fuels and fossil fuels are soon depleting and
alternative energies will be the ways that people will be living in the near future. As the positives of alternative energy will provide a healthier and
cleaner future, cost is something people underestimate. The price of alternative energy will increase our national deficit as well as the people's taxes,
as manufacturing these products that will create alternative energy is expensive. As the economy of the United States continues to fall apart,...show

However, the American Petroleum Institute, and American Gas Association were against extreme spending and are worried about the unstable
economy, and would rather have the usage of fossil fuels and keep people in business than spend billions of dollars towards alternative energy that
will save money in the future, and therefore are against the bill. I believe that API will have the most influence on S. 3813, as each member of the
organization has a specific job to try and persuade Senate to reject the bill. "The American Wind Energy Association was created in 2007" (Archive,
About AWEA, par. 1) "AWEA promotes wind energy as a clean source of electricity for consumers around the world." (Par. 2). They were created
after global warming was starting to become a national problem. "AWEA is a national trade association representingwind power project developers,
equipment suppliers, services providers, parts manufacturers, utilities, researchers, and others involved in the wind industry. In addition, AWEA
represents hundreds of wind energy advocates from around the world." (Par. 4). "AWEA supports policies to boost wind energy and slow climate
change." (Par. 5). They are working day and night to make sure that S. 3813 is passed. Their goal is to "increase Wind Energy to 15% by 2021."
(AWEA, phone interview) With the Ambition that AWEA shows, it will make every attempt to pass S. 3813 its priority. "AWEA has over 1200

5. Alternative Energy Essay
Modern alternative energy generation methods are limited by several factors including efficiency, inability to respond to sudden changes in power
demand, and susceptibility to environmental events. In 2010 the leading renewable energy sources were hydro–electric, wind, bioenergy, geothermal,
and solar Photo Voltaic (PV)[1]. Of these, hydroelectric made up 82% of the renewable resourceenergy generation, while the other means all
contributed about equally. These relationships can be seen clearly in the table below. Although hydroelectric makes up a large portion of the electricity
produced, it is not appropriate to discount the other sources due to the frequency where hydroelectric power generation is unpractical. It is important to

The addition of the dam can also have negative effects downstream, where water flow will now be restricted. These drawbacks often make a
hydroelectric dam impractical, and as a result cannot be the only form of renewable energy that we consider bringing into a smart grid.
After hydroelectric, the next leading energy producer is the wind turbine. In 2015, wind turbines across the United States generated roughly 226 billion
kilowatt–hours of electricity[3]. Wind turbines raise many different concerns from hydroelectric power sources because of how differently these
sources create electricity. The wind turbine operates by transforming the kinetic energy of the wind into electricity using a generator turned by the
turbine blades. The most notable difference in performance between these sources is that, unlike hydroelectric dams, which can in impractical or
simply impossible in some places in the world, the wind turbine is acceptable anywhere that wind is present. Though wind can be found everywhere,
there is a significant issue that the wind does not blow to match the demand for electricity. This means there are three states that these systems can
operate in. Should the turbines be permitted to spin freely, they could produce more electricity than is needed, or if it were a calm day, electricity
demands could outweigh the amount of electricity produced. It's almost impossible for the
