1. Earth's Natural Energy Sources Essay
INTRODUCTION
Renewable energy is energy produced from natural resources such as, wind, sunlight, rain, tides and
geothermal heat which can be re–used or replenished. Natural energies (renewable energies) have its
advantages and disadvantages. The reliance on fossil fuel is reduced by the sources of renewable
energy. Though the use of natural sources has many advantages over the use of fossil fuels, the cost
of investment for it can be too high for some people.
In this project, I will be highlighting mainly on the sources of natural energy and its advantages and
disadvantages.
EXAMPLES OF NATURAL ENERGY SOURCES
WIND
It is said that anything that has movement has kinetic energy, in which case wind is definitely going
to be considered as...show more content...
Furthermore, wind turbines takes op less space than power stations.
DISADVANTAGES OF WIND ENERGY
If we need to produce large amount of electricity, we need to have loads of wind turbines. However,
some people reckon wind turbines to be something that spoil the countryside.
HYDROPOWER
The word, 'hydropower' itself describes that it's something to deal with water. The utilizing of
energy in water is known as hydropower (also sometimes called as hydraulic power). It is
conceivable to collect the energy in moving water and convert it to useful power. The fact that
water is 800 times denser than air enables to get a significant amount of energy harvest even from a
slow flowing stream of water, or moderate sea swell.
One of the oldest examples of the use hydropower is watermill.
ADVANTAGES AND DISADVANTAGES OF HYDROPOWER
Firstly, this is a cheaper way of generating electricity as water used is free. No green house gas is
being produced while the electricity is generated. However, the cost to build dams is high.
Moreover, by building a dam, the nearby area has to be flooded and this could affect nearby wildlife
and plants.
SOLAR ENERGY
Solar energy is the energy provided from the sun. Though the other forms of renewable energy,
such as, wind, hydropower or biomass is thought of as separate forms of energy, they can actually be
drawn back to solar energy. Solar energy can also be referred as thermal energy as it provides heat.
We can use solar

2. Green Energy Essay
With an abundance of government–funded tax breaks and subsidies available to encourage buildings
to go green, it is no wonder why so many companies are interested in converting their real estate into
energy efficient areas. The ability to win a multi–million dollar tax break is quite a motivator, but
just how much are these companies really doing to turn their properties green? It turns out that
many will do the bare minimum to win over this green certification, and most end up using just as
much energy as they previously did. This is why a recertification effort needs to be done conducted
to ensure that green buildings are truly energy efficient and are not just products of managers
looking to save a few dollars. Such a project can be...show more content...
This means that they can do very little to do so by only taking the smallest steps needed to get 40
total points. They can do this by creating pleasant and healthy office spaces, using common building
materials, providing parking for fuel–efficient vehicles, implementing bike racks and showers, and
posting educational displays (Schnaars and Morgan). None of these actions actually reduce
emissions or make a building greener, but if a company completes enough of them, they can win
over subsidies regardless of how little effort they have put in.
It is not just LEED that has been promoting this mindset of only carrying out a bare minimum effort.
Organizations in existence such as the U.S. Green Building Council were created to help guide
companies to achieve green certification through the cheapest means possible. It has advised
universities to achieve green points by offering courses on green building, told employers to give
workers a video game room and fitness center, and instructed builders to create fire–alarm systems
that minimize the stress on firefighters all with the intention to buy easy points (Schnaars and
Morgan). Considering that a building only needs 40 of these points to be considered green, it seems
much too easy for them to achieve green certification by doing things that barely make them green at
all. One way to make companies and buildings step

3. Green Architecture Essay
Green Architecture is a method to reduce the impact on our environment by using natural resources
like energy, water, and the materials that are used in the structure recycled materials or the fixtures
used in the home with energy saving features, as well as making a healthier environment. With
high–efficiency windows and high value insulation in the walls and floors you're your energy would
take less too cool or heat up that area.
Written by BOB BOB BOB May 2010 "The history of a green building goes back further than the
70's in the middle of the industrial revolution that Henri Becquerel first witnessed the transformation
of solar energy into electrical energy. Around this time, the late 1800's to early 1900's, a number of

The use of fans, vents and blowers are used to distribute the heat in the areas that are needed when
a roof and walls are built they are made to be well insulated with the windows letting in heat the
insulation in the ceiling and walls absorb it and slowly letting off the heat. If an area is a little
bigger than sky lights or more windows are used to bring in more heat.
With the landscape of the outside in mind as well if you have plants that require more attention
then that cost more energy to take care of them. Think of plants that use less water conserving
energy will take less to heat or cool your home if you were to have an asphalt drive then it will put
off more heat making your use of air conditioning higher to keep the home cool use a natural source
of rock to lessen the energy in the home.
If you were to do your laundry or the main energy usage on a sunny or windy day your going to
have more energy to complete your entire task then you wouldn't be using your back energy to
complete them that is going require the most of your energy sources.
Making a home with multi function energy sources gives a wide variety of endless energy with all
of them combined it can easily give energy to a home. There is going to be sunny days for your
solar energy windy and rainy days for your energy as well so having all sources will make an easier
life for your home and less hectic.

4. Essay about Renewable and Clean Energy
As these days global warming, pollutions and fuel shortages are getting more and more serious
through time, renewable and clean energy is increasingly the ideal solution to energy related
problems we have to solve one way or another. Biofuel is currently one of the mainstream and
highly supported solutions, an idea to make renewable fuel by living organisms such as fiber, corn,
vegetable oil or sugarcane. Biofuels, unlike nonrenewable fossil fuels over extracted by people,
contains the potential to tackle most of the problems people encounter when using fossil fuels. This
makes renewable fuels making it a cleaner source of energy, and a better option than fossil fuels that
will ran out shortly sooner or later. The two main categories in...show more content...
The second part of the essay will discuss some of the weaknesses in applying the fuel into
practical usage. For example, corn ethanol is currently encountering technical limitations serving it
as a standalone fuel, meaning that corn ethanol can only function by combining it with a certain
amount of gasoline, while gasoline is a kind of fossil fuel. Finally, this essay will conduct a
comparison with other renewable resources in the world, including solar power, other biofuels, and
hydrogen fuel. The most noticeable advantage of corn fuel as an enhancement of fossil fuels is
also the biggest advantage of ethanol energy a renewable fuel. Gasoline as a fuel is extracted from
petroleum, and what makes petroleum an unreliable source of energy is that petroleum is
nonrenewable, meaning it would run out some day in the future. Contrary, corn ethanol is a
renewable source of energy, meaning if corns are replanted and remade into fuel, corn ethanol can
be a long–term, sustainable energy source (gracelinks.org). Corn ethanol has the potential to produce
a perfect solution of the energy crisis that will happen sooner or later, as experts predicted petroleum
will run out in around fifty years (Gupta,p15). Another main benefit of corn fuel as the future fuel is
that the

5. Green Energy
In the environment there are many concerns on how to make this a better place to live. One of the
biggest issues is our energy and power sources. Green energy is a term used for sources of power
and energy that are environmentally friendly. Basically this includes anything that is renewable
energy.Renewable energy is considered energy that is constantly being replaced such as wood,
vegetable matter, and trash. Green energy 's main focus is to use sources that can cut down on
pollution. Some of these sources of power and energy are Biomass energy, geothermal energy,
hydropower, nuclear energy,solar energy, wind energy and tidal energy. People hope that these will
help use more natural sources to produce energy. In several countries you...show more content...
Next time you get on your computer you can set up your computer to where the sleep mode is on
and also the hibernate comes on after thirty minutes. Another thing is taking control of the
temperature. During the winter you can set your thermostat at 68 degrees or less during the day
and 55 degrees at night before you go to sleep. During the summer you can set it at 78 degrees or
more. Also you can set your thermostat on your water heater between 120 and 130 degrees. The
only drawback with this one is you can take really long hot showers. So with all these information
you can decide if you are for or against green energy. I believe we should start doing something
about our environment before we are too late. I personally am for green energy. You don 't
necessarily have to go out get green energy as your electricity source but doing little can always
help our universe. The good green energy is that there are several sources of energy that we can
use and if using these types of energy help clean up our air pollution and atmosphere I 'm all for

6. The Power Of Green Power Essay
Green Power
Energy is everywhere it 's in your phone to your community's hospital. Many years ago humans
lived with no energy supply, now in 2016 it 's essential. As energy was discovered and objects
which consumed such energy the demand increased, as a result so did the search for sources to
obtain such power, people relied on coal, nuclear power, etc. all which contaminated the planet.
However, there are also alternative energy power produced by renewable resources such as, solar
with solar panels, river currents hydro power, or even wind with wind turbines. Wind turbines are
seen along the road, but what are they? Why should people keep pursuing this energy source? Wind
turbines work to produce energy, and are also essential, not only for people but for the planet.
What is a wind turbine? A wind turbine, is the process in which a turbine takes wind and produces
clean energy(electricity) free from harmful gasses, to power this turbine wind is needed but how
is wind obtained? What is wind? "Wind is a form of solar energy and is a result of the uneven
heating of the atmosphere by the sun, the irregularities of the earth 's surface, and the rotation of
the earth"(How Do Wind Turbines Work?). In other words wind is a renewable source such as solar
energy. It 's produced when warm air rises to the atmosphere and later on is cooled down making it
sink down, as warm air goes up cool air takes its place causing what we know as wind. Therefore the
way a wind turbine will perform
