Earths Natural Energy Sources Essay - 1470 Words

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 solarShow MoreRelatedThe Hidden Treasure Of Wind Energy1453 Words   |  6 Pagesof Wind Energy During the course of history, this country has been seeking new forms of energy that will provide clean energy and also preserve Earth’s lifespan. The use of renewable and non-renewable resources has been a major controversy throughout history. Renewable energy such as wind power has been a main focus of this issue. Many believe wind energy is the best renewable power source over many others because it is the cleanest and most efficient, whereas, others view wind energy as a timeRead MoreClimate Change Is An Important Issue That Concerns Humanity999 Words   |  4 Pagestemperatures. Every day, the enhanced greenhouse effect continues to advance, which significantly influences Earth’s long-term climate. In addition, human activity is also contributing to the increase of global warming and is already leading to harmful consequences. Some people believe that global warming is not occurring and the heating of the globe, is just a part of the Earth’s natural cycle . Several consequences such as, ice caps melting, show us that global warming is in fact occurring. ThereforeRead MoreEssay on Global Warming and the Greenhouse Effect 1500 Words   |  6 PagesWarming is due to the greenhouse effect. The greenhouse effect is a naturally occurring process that aids in heating the Earths surface and atmosphere. It results from the fact that certain atmospheric gases, such as carbon dioxide, water vapor, and methane, are able to change the energy balance of the planet by being able to absorb longwave radiation from the Earths surface. Without the greenhouse effect, life on this planet would probably not exist as the average temperatureRead MoreDepletion of Non Renewable Resources of Energy1422 Words   |  6 PagesA  non-renewable resource  is a  natural resource  which cannot be produced, grown, generated, or used on a scale which can  sustain  its consumption rate, once depleted there is no more available for future needs. Also considered non-renewable are resources that are consumed much faster than nature can create them.  Fossil fuels  (such as  coal,  petroleum, and  natural gas), types of nuclear power (uranium) and certain  aquifers  are examples. Natural resources such as  coal,  petroleum,  oil  and  natural gas  take thousandsRead MoreWhat Factors Influence Earth s Climate?903 Words   |  4 PagesEmily What factors influence Earth’s climate? Earth’s climate, or the particular weather patterns over an extended period of time, has many contributing factors and has varied over the course of the planet. The planets’ global climate can also be broken down into regional climates based on the weather patterns of a specific area of land. These differing regional climates are averaged together and all contribute to the overall global climate of the planet. The Earth’s global climate effects factorsRead MoreEnergy Conservation Essay1345 Words   |  6 PagesThe topic of energy is one that is seen in the news more and more as each day passes. As most Americans can tell you these days, energy is essential for industrial and technological development in this or any other country. However, some believe that certain traditional methods of producing energy, such as burning fossil fuels, are depleting the earth’s limited supply of natural resources and may also be harmful to the environment. They encourage the use of renewable sources of power, such as windRead MoreThe Effects of Global Warming on the Earth990 Words   |  4 PagesGlobal Warming Earth’s temperature is a vital aspect to Earth and its surroundings. The atmospheric temperature along with natural gases is the significant reasons why Earth inhabits all of its life. When there are changes that alter the natural affects of Earth’s environment there are factors that places the environment at risk. Increase warming of global temperatures account as a major concern of Earth’s surroundings. Global warming is a prominent source to consider how and why the environmentRead MoreDifferent Types of Energy and Its Many Uses969 Words   |  4 PagesIn the world today there are five different forms of energy available to us to use: mechanical, chemical, radiant, electrical and nuclear. (Tillery, 2009 p. 62) Each of these forms of energy can be converted from one type of energy to another. An example of this would be electrical energy turning into mechanical energy every time you use your blender. The electrical energy flows through the mechanical devi ce providing it the power it needs to make the blade move in a circular motion and blendRead MoreGlobal Warming Is The Environmental And Social Changes Caused By Human Emissions1652 Words   |  7 Pagescontrast natural versus anthropogenic climate changes of global warming, mitigation strategies, mitigation effectiveness, policy implications, costs, and address some policy changes to help stabilize global climate and strict standards for business sectors or nations. Natural Climate change The Earth has been experiencing a considerable amount of climate change for the last several decades. Natural factors that contribute to the climate system consist of: volcano activity, solar, and earth’s orbitRead MoreGreenhouse Gas Emissions And Climate Change967 Words   |  4 Pagesresponsible for all of the energy that enters the Earth’s atmosphere. The Earth s energy is in balance when Earth emits the same amount of energy as it absorbs (Schneider, 1987). But today, the Earth is absorbing more energy than is what is being released due to increases in greenhouse gases in the Earth’s atmosphere (Herbert, 2007). Out of the total energy entering the Earth’s atmosphere, as seen in Figure 1, only 30% is being reflected back into space due the Earth’s albedo (Schneider, 1987). The
