Renewable Energy


I am an environmentalist who is in favor of using renewable sources of
energy rather than non - renewable sources. There are several types of
renewable resources of energy.

1. Solar energy.

2. Wind energy.

3. Hydroelectric energy.

4. Geothermal energy.

5. Biomass energy.

It is better to use renewable resources of energy rather than non -
renewable sources in the long term. Eventually the limited supplies of
non renewable sources of energy will finish. You would then need to
find another mean. Why wait for the non renewable source of energy to
finish instead we can use renewable sources of energies. All renewable
source power stations do not produce emissions that pollute the
environment. The damage done to the environment is quite small
compared to that of non renewable powered stations. Using renewable
energy reduces pollution, conserve land, and to save money.

Renewable energy conserves natural resources by reducing the need for
non - renewable energy. Some natural resources are renewable, meaning
they can be replaced, and some are not. Paper, corrugated board, and
other paper products come from renewable timber sources. Trees
harvested to make those products can be replaced by growing more
trees. Iron and aluminum come from nonrenewable ore deposits. Once a
deposit is mined, it cannot be replaced. The natural resources such as
trees form biomass energy. This saves limited oil reserves.

Solar energy is very efficient compared to coal, oil and gas powered
stations. The efficiency of a solar powered station varies between 40%
and 80% but for an oil powered station it may range 30% to 40%. A
solar powered station is therefore more ideal than a coal powered
station since much of the energy is lost.

However users currently pay 6 to 7 cents per kilowatt-hour for
conventionally generated electricity. Eventually as renewable sources
of energy becomes more popular the price will drop as no fuel cost is
needed.

Using oil, coal and gas means that explorers and miners are in more

Renewable Energy: A Bright Future Essay

- In chapter thirteen of our book, Environment by Raven and Berg, it shows us just how important renewable energy sources are. Currently the United States of America thrives on the use of fossil fuels and nuclear power. The main problems with these types of fuel are that they are both limited and can be extremely harmful to our environment. They cause global warming, air pollution, acid rain, and oil spills (Environment), and not only that, but in the grand scheme of things, these sources really aren’t even that cheap of a fuel source....   [tags: Renewable Energy, ]

Energy Of Energy And Renewable Energy Essay

- Energy is used in various everyday situations and activities. The ability to perform work or do vigorous activity is defined as energy (The American Heritage® New Dictionary of Cultural Literacy, 2005). Energy has two extensive categories: kinetic energy and potential energy (Trefil & Hanzen, 2013). Kinetic energy is energy with motion inside an object or the motion of the object and potential energy is energy that is stored or saved for future use (Trefil & Hanzen, 2013). There are numerous energy sources; however, energy sources are categorized into two types: renewable and nonrenewable (Trefil & Hanzen, 2013)....   [tags: Energy, Wind power, Renewable energy]

Renewable And Renewable Energy Sources Essay examples

- Most of the energy sources used today are not renewable and are therefore not sustainable in the long term. Also, the method of burning fossil fuels is harmful to the environment due to the release of carbon emissions which leads to detrimental climate change. Finding an efficient and renewable source of energy to eventually replace fossil fuels is necessary in order to reduce the contribution to the buildup of carbon dioxide in the atmosphere, which has many implications on the biosphere. Some of the promising alternatives to non-renewable energy sources are biofuels....   [tags: Photosynthesis, Carbon dioxide, Renewable energy]

Renewable Energy : The Energy Essay

- Many energy company prefer to use renewable energy because it cause less pollution. The major renewable energy are wind energy, solar energy, and other clean energy from the nature. Wind energy uses the combined kinetic energy of all the air molecules, therefore, it is a free and renewable energy source. The wind energy is the kinetic energy formed by the large amount of flowing wind in our atmosphere. The power of the wind energy is determined by the speed of the wind. Wind power is approximately proportional to the cube of the wind’s speed....   [tags: Wind power, Renewable energy, Energy]

Essay about Alternative Sources of Renewable Energy

- With a growing population around the world, the need for energy is growing as well. We are accustomed to using fossil fuels as our central source of energy for everyday uses. Fossil fuels are a natural matter that is found in the ground of the Earth formed in a previous time period millions of years ago that are nonrenewable and are used for energy today. Fossil fuels have to be burned in order to produce energy. When nonrenewable resources have been used, they cannot restock themselves or ever be used again....   [tags: Renewable energy, environmentalism, environment]

Renewable Energy : Fossil Fuels Essay

- Renewable energy is the key to replacing the use of fossil fuels, by increasing the use of natural resources to power energy sources. By promoting the use of renewable energy it would result in a decrease in negative environmental impacts. Fossil fuels are the main contributor to global warming, air pollution, acid rain, and oil spills (Pacific Environment, 2014). The dependence upon fossil fuels for energy has created a major environmental catastrophe, resulting in the loss of many ecosystems. As stated in Ibraham Dincer’s review; if humanity expects to continuously depend upon energy systems the environmental impacts need to be contemplated rather than pushed aside (Dincer, 2000)....   [tags: Renewable energy, Wind power, Hydroelectricity]

risk. Accidents such as mine collapses cause a lot of loss in life or
a power station explodes. A renewable source of energy is safer to use
and handle than its counterparts. A nuclear powered station is also
radioactive and its waste is also harmful to the population. Using
renewable sources does not leave behind much harmful wastes.

The initial cost of adapting a renewable source of energy may be
costly this is the sort term effect. The long term the cost of the
renewable source of energy will decrease. This is because you would
not need to pay for the source of energy for the renewable type. E.g.
you would not need to pay for sunlight. Only the running cost would be
needed. If however you continue to use non-renewable sources of energy
you would need to pay for the fuel and running costs. E.g. If I build
a non - renewable source power station and pay $ 1000,000 to
construct, $500,000 for fuel and $100,000 to run I would only need
$1000, 000 (for hydro =electric power station) to construct a
renewable source power station and $50,000 to run. You would therefore
save approximately ½ a million in money and the use of limited
non-renewable resources.
