why do we need alternative sources of energy

The earth is a fragile planet, and the ways in which human beings use it directly affects its health. Harvesting fossil duels and then burning those fuels releases harmful chemicals into the earth s atmosphere and oceans. This is one of the major reasons why it is so important to find alternative sources of energy. People take for granted what their actions do to the environment. When people talk about alternative sources of energy the often refer to the. In this category we have:
One thing is certain, and that is the negative effects of the carbon oxide spewing energy industry are immense. The culprits that the humans of the world relies so much on for their daily energy needs are: Smog one of the awful effects of oil, gas and coal burning Green alternative sources of energy has the potential for reversing some of the damage human beings have brought upon the earth. However, it might be too late for some regions. Part of the problem lies in the fact that overpopulation makes the reduction of smog a difficult task. China has one of the fastest growing populations found anywhere in the world. Recent independent studies show that major metropolitan areas, such as xingtai and shijiazhuang, contain extremely unhealthy levels of air pollution. Smog is a mixture of naturally-occurring fog combined with pollution caused from cars and industrial factories. More recently, pressure placed on china by the international community has caused leaders within the country to create a spin cycle of misinformation.


Specifically the now notorious five surprising benefits of pollution. When people consider alternative sources of energy, they often think about how these sources save the air. In reality the worldвs oceans are in peril too. This was evident most recently during the gulf oils spill occurred. One of the worst oil spills in history occurred from a ship called the exxon valdez off of alaska in 1989. The gulf oil spill was the result if an explosion which happened on anoil rig many miles out to sea. Some of the workers lost their lives in that explosion, and oil began to spew from deep inside the earth out into the ocean. As a result, oil slicks and balls of jelly-like oil began to wash up on beaches along florida, mississippi, new orleans and other locations. These kinds of disasters can be averted if more proactive approaches to alternative sources of energy take place. Wildlife such as birds, fish, otters and other marine animals will not have to suffer at the hands of human beings. A not so well known but just as dangerous new energy extraction form is fracking for natural gas. Fracking is a controversial process in which drills mine deep into the earth to recover gas hidden behind shale rock. Once the drill has reached the desired depth, high pressure water and chemical mixture is blasted into the rock to release the gas inside, thus making it recoverable by drill teams. This practice has been met with skepticism and concern. Critics point to how the process could leave the ground unstable.


Pollution could result from the high pressure water and chemical mixture which is used as well. could reduce or eliminate the need for this dangerous practice. Utilizing the sunвs energy with solar power, harnessing tidal power or building wind power plants enables us to operate machinery and major production sites without harming the interior of the earth. Alternative sources of energy are critical to maintaining health both on the earthвs surface and under the ground. Sometimes small steps in energy usage go a long way in from the wounds we have inflicted. If we hope to provide a safe place for our kids and their kids, then we must all take a close look at ourselves. For example, you can obtain warm water by heating it with a, buy an electric car or you can drill a for all your needs. Even small steps like having a compost, recycling or making the conscious choice to buy ecological food helps. People who practice the use of green energy are in better health overall as well. Pollution, even microscopic amounts, can wreak havoc on the human lungs over time. Our bodies can handle only so much abuse. Take the steps necessary to ensure that our world is a safe place to live for many years to come. ( 4 votes, average: 4. 00 Loading. There is a current global need for clean and renewable energy sources. Fossil fuels are non-renewable and require finite resources, which are dwindling because of high cost and environmentally damaging retrieval techniques. So, the need for cheap and obtainable resources is greatly needed.


An efficient and more feasible alternative option is solar energy. Solar energy is a more practical type of energy due to its plentiful availability; it is derived directly from the sun. In 2010, renewable energy only provided 8 percent of the total energy consumption in the United States. Many people probably wonder: if renewable energy is so beneficial, why don t we consume more of it? The answer to the question is that many of the renewable energy sources are more expensive and more difficult to retrieve. Thus, because of these limitations, the consumption of fossil fuels has grown to an exorbitant rate. Although there has been an increased effort to incorporate solar power, these efforts have not alternated its use by a great amount; less than 1 percent of the electricity in the United States is supplied by solar power. In the United States, California utilizes the most solar power. After it was denied funding by the federal government, a solar company, received private funding from Bank of America Merrill Lynch. This project will ultimately provide solar electric panels on roofs for over 120,000 military housing units and spans over the next five years. The bank has agreed to lend up to $350 million for the implementation of the project. The new undertaking is a huge leap for the solar industry. Renewable energy sources, specifically solar power, can be extremely practical as alternatives to damaging carbon-intensive fuels. Original article by Jill Dolowich for MNN
