Ever since the Industrial Revolution, fossil fuels have been used to power the World’s economy. When the world first discovered oil as an energy source in 1859, it seemed like an ideal source of energy. Energy that had no limits and no negative effects. It is now clear that thinking of fossil fuels as a limitless supply of free energy without any negative effects is a very foolish mindset. However, this mindset was so prevalent throughout the entire twentieth century that America and many other nations around the world have become totally dependent on fossil fuels as their main source of energy. The problem with being so dependent on fossil fuels is that they are in limited supply in the world and they are non-renewable. In fact, the world …show more content…
Geothermal energy is found in the form of heat from magma and decaying radioactive materials deep beneath the Earth’s surface. It is completely renewable because energy is constantly being produced in the mantle. There is a huge amount of energy beneath our feet just waiting to be harnessed. There is more energy within 10,000 meters of the Earth’s surface than there is in the world’s entire supply of oil and natural gases combined (Union of Concerned Scientists 1). If only a small fraction of this energy were to be collected and used to power human necessities, dependence on fossil fuels and the pollution they cause could be significantly reduced. A study done in 2007 by the Massachusetts Institute of Technology concluded that, using current geothermal energy harnessing technologies, 6% of the United States energy needs could be provided by geothermal energy at a cost of just $40 million per year (Rich 1). Additionally, future research on geothermal energy could produce technologies capable of harnessing energy even more efficiently in the future. Geothermal energy is a powerful tool that could be used to decrease the use of fossil fuels and carbon-dioxide …show more content…
Wind is a completely renewable source of energy and converting it into usable electricity does not produce and harmful emissions. Using wind to produce energy is a science that is very successful and on the rise. The world’s capacity to generate energy from wind is growing by 29% each year, in comparison to a 1.7% growth rate for oil (Rich 1). With scientific advancements making wind energy more and more valuable each year, investing in windmills and other machines that harness wind energy should be a no-brainer. Many countries in Europe, in fact, have already put major funding into wind energy and are reaping the benefits of doing so. By 2020, it is expected that half of Europe’s energy needs will be met using wind power (Rich 1). Other nations can experience the same success many European nations have had if they stop using fossil fuels and start using wind energy. According to a study done by the Department of Energy, the United States receives enough wind in the states of Texas, North Dakota, and Kansas alone to power the entire nation (Rich 1). Harnessing this energy would reduce America’s dependency on fossil fuels drastically. Energy from wind is one of the most reliable and renewable energy sources in
Fossil fuels are an important part of life. When you turn on the lights, watch TV, or take a shower, the electricity that you are using is being generated by fossil fuels. The three types of fossil fuels are coal, crude oil, and natural gas. They all take millions of years to form, so they are considered to be “non-renewable”- eventually, the fossil fuels will all be used up. One dangerous biological effect of using fossil fuels is ocean acidification. Extracting and transporting fossil fuels can
around the world are using more and more fossil fuels every day. Many people think- fossil fuels can’t be that bad, we’ve used them for decades! Nevertheless, fossil fuels are much more harmful then they seem. This energy source can cause damage to human health, harm to the environment, and a downfall to the future of energy. However, there is another source of energy commonly overlooked. Starting off, these fossil fuels are affecting human health. With fossil fuels on the rise, the chances of cancer,
New Energy for the Future For years man has relied on energy in order to be successful in life. The industrial revolution relied on coal for the new inventions brought into the world. Life as has never been the same since then. However since that time, there has been little done to improve on energy efficiency and humans still primarily rely on fossil fuels for energy. For over a hundred years the Earth has become more polluted and dirtier than ever before. Now, with new, innovative technology there
world. In order to do this, fossil fuels have been the sole source for most of these mechanics-such as buildings, vehicles, electricity, etc. However, as mankind progresses in these advances, the demand of power sources increases with each given year, thus the world’s fossil fuel reserves are depleted at an alarming rate. In addition, the continuous use of these non-renewable resources results in deadly implications. Although fossil fuels are a suitable source of energy, renewable resources are essentially
Fossil fuel plays leading role in upsetting environmental and climatic protection. Our earth is at catastrophic risk by the exploitation of fossil fuels. Therefore, Pressure is on to find viable alternatives for energy to save bring a clean revolution. In that case, Bio-fuels make an attractive alternative for energy than fossil fuels. Various provocative questions need discussion that what are the attractive differences between both the fuels, why fossil fuel dependence are to be actually minimized
The use of Fossil fuels, such as coal and oil, belongs the past. Fossil fuels are natural fuels that are formed when remains of dead organisms pass through episodes of natural processes such as decomposition and disintegration; that exceeded millions of years. Fossil fuels include coal, oil and natural gas; they are categorized as fuels due to their ability to release energy when they undergo combustion. Meanwhile, they are the main source of producing the energy that is consumed by humanity
The need for nuclear energy is more widespread today than it has been for decades. Drastic climate change and the rising prices of fossil fuels such as oil have made many scientists seek an alternative energy source. Although nuclear energy has been around for decades, the use of it has always been approached by pessimism. Because, the misuse of nuclear energy could spell disaster for any country involved in the process. Events like Three Mile Island, Chernobyl, and Japan’s Fukushima accident are
addiction to using fossil fuels.” Reuben is suggesting that the addiction to burning fossil fuels abuses nature consistently and humans take our natural resources for granted. The world has a heavy dependency upon fossil fuels such as oil, methane, coal, gas and petroleum. As population and industry grows and reliance on these non-renewable energy sources multiplies, how are fossil fuels negatively impacting Earth? The adverse effects of fossil fuels is staggering. Fossil fuels are responsible for
Non renewable energy, such as fossil fuel, is used all over the world. Big part of the population assumes that fossil fuel is a reliable source of energy, easy to obtain, and is relatively cheap. On the other hand, fossil fuel is a non renewable energy, which means that we can use it only once. Also, this burning fossils are not good for the environment and are the main reason of the global warming. In this era a lot of new technologies have been invented. Although not every created invention has
There are three main fossil fuels; oil coal and natural gas were all formed hundreds of million years ago before the time of the dinosaurs (Energy Quest, 2012). The period of time that the fossil fuels were formed was the Carboniferous Period. It got the name from the word “carbon” which is the basic element in coal and other fossil fuels (Energy Quest). According to (Energy Quest, 2012) these fossil fuels were formed in prehistoric times from a material called peat which after enough pressure
The world is dependent on fossil fuels as the prime source of power to meet our energy demands. What are fossil fuels? “Fossil fuels come in three major forms-coal, oil, and natural gas. Because fossil fuels are a finite resource and cannot be replenished once they are extracted and burned, they are not considered renewable.” - (United States Environmental Protection Agency) When the supply of fossil fuels is completely exhausted, what will we rely on to meet our energy needs? An alternative option
Renewable energy is a very reliable source of energy in most parts of the world, but the question on most conservationists and scientists minds is if South Africa could use renewable energy efficiently and effectively. Renewable energy could be the solution to many of the country’s economic problems such as the supply and demand of electricity, the costs of electricity, and the need for jobs in South Africa. In this essay I will be explaining the expenses and down sides to renewable energy, and i
Energy is one of the most fundamental of human life, it is required for wide range of application and usage, the most common that can be point out is transportation, industrial application, and agriculture and food industry. Energy can be found any form and type like, heat, chemical, electrical and even nuclear. Before discovery of fossil fuels wood was the only source of energy, however it all changes by inventing internal combustion engine and also discovery of oil, since then human found themselves
Do you know what type of fuels your house is using right now? The answer is most likely fossil fuels. About 95.4% of fossil fuels are used for transportation and 66.4% are used for electric energy in the U.S alone. If you do not know what fossil fuels are things such as coal, crude oil (petroleum), and natural gases which are extracted from remains of prehistoric plants and animals. The uses of these fuels are proven to be detrimental to the environment and the human health. We are also quickly
Fossil fuels are natural fuels that are derived from the remains of living organisms and are a major energy source in the world. These fuels include coal, oil, and natural gas which are not renewable; they cannot be synthetically created or manufactured. Once they are used, it will be another million years to refill what the humans have used up. Although natural fuels are popular, they have many drawbacks. The consumption of fossil fuels have led to the greenhouse effect – the damage to the earth
