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. Therefore, higher speed winds generate more power. So, how do we convert the wind energy into electricity that can be used for our everyday lives? Wind turbines are being built in wide, open area so that when the wind blows, it will turn the blades of the wind turbines. This kinetic energy will then be converted into mechanical power that can be used. The generators will then convert the mechanical power into electricity to power our homes and etc. However, it is not easy to pick an area to build the wind turbine. Companies need to consider many...

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]

Adaptation of Renewable Energy Essay

- Renewable energy is generated from natural resources such as sunlight, wind, rain, tides, and geothermal heat. On October 5, 2010 the U.S. Department of the Interior (DOI) approved the first sizeable solar energy plants to be built in California which will be divided into two developments totaling 6,800 acres of public land. This project is estimated to last 30 years while generating almost 1,000 new jobs. The solar energy technology that will be used in California’s Imperial County is called the sterling energy systems SunCatcher technology....   [tags: 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]

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]

Energy Sources For Renewable Energy Essay

- Renewable energy sources have been found to cost more than the benefits that are received from the energy sources. There are many different resources that you can use including water, wind, solar, geothermal, and biomass. These energy sources can differ in cost depending on capital, fuel, and operations and maintenance. Some of these sources are not cheap to build but once they are up and running, they have no fuel cost. There are many reasons to determine when, where, or how an energy source is used....   [tags: Wind power, Renewable energy, Solar energy]

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]
