Thomas Edison once said, “I have not failed 10,000 times. I have succeeded in proving that those 10,000 ways will not work,” he said of his method of experimentation. “When I have eliminated the ways that will not work, I will find the ways that will work.” Up until the late 1830’s electricity was derived from many non-renewable sources such as coal, oil, and natural gases. These are also known as fossil fuels. Fossil fuels are the major energy sources that are being used in the world today. The production of fossil fuels account for more than one-third of U.S global emissions, which trap heat, steadily drive up the plant’s temperature, and create harmful impacts on our health, our environment, and our climate. Their sources are limited and depleting at a faster
America should pursue alternative energy sources because “With only 5 percent of the worlds population, the United States consumes almost one-quarter (22.5%) of global energy”. (((Josef Bram, 15))) With such a small percentage of the world’s population and still one of the largest consumers of energy the U.S should be looking for new and better ways to generate energy. Currently The U.S’s energy is supplied using traditional sources. According to Canadian scientist and policy analyst Vaclav Smil “Todays energy 29% from coal, 33% from oil and gas, and 33% from soft-energy (alternative sources)” (((Smil, 47))) Most of the energy we use on a daily basis is not produced using clean methods. Some alternative energy sources that are already in place within the United Stats are wind, solar, and hydraulic.
In this paper, we focus on using fossil fuels causing climate change. Fossil fuels are fuels formed natural resources such as coal, petroleum and natural gas, which are the most widely used fuel and industrial chemicals in the world. Since industrial revolution, fossil fuels bring a very great quantity convenience and technological products. So we can use cars, planes and all modern products. But fossil fuels cause climate change at the same time. Greenhouse gas, nitrous oxides and a great deal of harmful gas which are from fossil fuels are causing serious environmental problems. Therefore we need to be concerned about the problems caused by fossil fuels and the solutions.
The Alternative energy industry in the United States has been at a steady rate of growth for the past decade, however there is still controversy over the use of renewable energies, their impact on the economy, and their impact on the environment. As controversial as the topic is, the argument boils down to a moral need to support environmental regulations, and an economical need to sustain domestic growth in the Energy industry of the United States. Mainly, the question is can alternative energy effective replace fossil fuels? There are of course arguments for both sides of this question.
For over forty years now, scientists and researchers have been tirelessly searching for an alternative to fossil fuels. Biofuels have become an interesting contender in the search for the replacement of the non-renewable energy source. Biofuels have been used throughout history for over thousands of years. There is a large debate over biofuels and its true impact on the environment. Those involved in the discussion debating whether biofuels have any real overwhelming benefits compared to fossil fuels could argue for its usage. According to recent research performed by the University of Michigan, biofuels may not be the best alternative for fossil fuels. Regardless of its impact on the environment, biofuels are becoming more popular particularly when the price of oil rises.
In this day and age, we have new energy sources that could be used to power our homes and transportation. Wind and solar power are used all over the world, but are still used far less than fossil fuels. Most would say it’s not reliable or it doesn’t make any profit. While both statements are true, it doesn’t mean we can’t make a better future using renewable energy. In fact, the only reason we don’t use renewables for everything is that we don’t want to change. The hard truth is we need to change. Fossil fuels are great right now, but if we run out, humanity must have another source of energy.
Abstract – The world can’t be imagined without IC Engines ,as their applications are wider in various fields. And mainly used input for this engines are fossil fuels. But the challenge in this is decreasing rate of resources. The fossil fuels may not be available after some years if they used in the same way .Not only the fossil but also the electric power is the non renewable energy, This paper concentrates to run the engine without fossil fuels or electricity.
Polar bears are the most known animals for the impacts of climate change on species. Global warming has been most prominent in the Arctic, and this trend is expected to continue. Their dependence on sea ice makes them highly vulnerable to a changing climate. Polar bears greatly rely on the sea ice environment for traveling, hunting, mating, resting, and in some areas, maternal dens (WWF). Specifically, they depend heavily on sea ice-dependent prey such as seals. Additionally, their long generation time and low reproductive rate may limit their ability to adapt to changes in the environment. Every time people breathe or burn something, oxygen in the air is converted to carbon dioxide. The carbon dioxide is used by plants to breathe and is converted back to oxygen, creating a cycle. If there is an increase in oxygen burning, for example, burning a lot of coal or oil to generate electricity or run cars, and cut down trees, the amount of carbon dioxide in the air is increased. This makes the air thicker and warms up the earth. The amount of warming is only a few degrees but it is enough to disturb the fragile balance of nature, which in turn will melt the polar ice, raise sea levels, cause violent hurricanes and endanger species such as polar bears. The polar bears are just one example of endangered animals because of the high demand of human need for energy which is acquired by burning fossil fuels.
Since, fossil fuels have been a part of our environment for some time now, they have been the main resource we’ve needed and used to keep our country running. The truth of the matter is, since we obtain fossil fuels from plants and animals that lived millions of years ago they will soon be gone. As indicated by Eric McLamb, founder, chief executive officer, and president of the ecology communications group, “The problem is fossil fuels are nonrenewable. They are limited in supply and will one day be depleted.” People realize that the crisis of running out of fossil fuels is upon us; however, these same people are timid about moving on to renewable energy. One main reason is because individuals do not believe renewable energy is cost efficient. For instance, solar energy is known to be fairly expensive, particularly more expensive than the conventional energy used now, which makes people uncertain about changing to renewable energy.
The U.S. should replace fossil fuel with renewable energy. There are many reasons that the U.S. can use renewable energy to improve the economy. First of all, renewable energy can have a more stable price. Unlike fossil fuel, renewable energy is a continual source of energy that will not be as demanded, and will not cause inflation. Next, using renewable energy is a key to having a clean and green environment. It will not cause pollution to the environment and will keep cities clean. Finally, the United States can provide more efficient jobs for unemployed workers. People will have more opportunities for jobs like installing or building any source of renewable energy. Replacing fossil fuels with renewable energy can be more efficient because it will have a stable expense, it is a clean way to help the environment, and it can provide several jobs.
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 also be very dangerous. Environmentally damaging accidents such as groundwater contamination, land subsidence, and oil spills occur frequently. Global warming is another possible environmental effect. Fossil fuels have a crucial role in modern
As we all know the energy we use form fossil fuel is nonrenewable, and it damages our environment badly. The most energy is used in the industrials (31%), the second is used in transportation (28%), the third is used in residential (22%), and the last is used in commercial (19%). We also know that the more we use fossil fuel, the more greenhouse gas effect to our earth and killing our atmosphere by trap the gases and it make our earth getting warmer and warmer. In this paper will go deep more into the second big use energy which is transportation and how they are going to use the new energy to keep the environment cleaner. However, our world has created a lot of renewable energy such as energy from solar, wind, geothermal, hydroelectric, biomass, and nuclear. In fact, the new Bioenergy, which uses household garbage, including food waste, for its fuel could be a great idea to save our natural energies, also less emission on the greenhouse effect, save money instead of wasting it.
Fossil fuels are essential to life on earth as we know it today. Our world would certainly be much different if it weren’t for such seemingly simple things such as coal, oil, and natural gas. These basic elements of life on earth may not seem like a major concern to some people until we put into perspective how they have shaped our world today. Civilizations have been built, economies have risen and crumbled, and even wars have been fought over these precious fossil fuels. However, these fossil fuels serve us in ways we may never truly appreciate, as long as we use them as recklessly as we do now. The major entity about fossil fuels is concerning their longevity and permanence in our world, and we all know, they will be around forever.
Finding energy sources is an issue that polarizes scientists, politicians and citizens alike. The most critical points of this debate are at fossil fuels and renewable energy. Energy efficiency is arguably the most dire concern facing the planet, because it significantly impacts all areas of everyday life. Common ground can be found in this controversy because both parties do agree that humans have a responsibility to future generations. That responsibility is to preserve the resources of the Earth, while offering this generation energy that is affordable and accessible.
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 is an opportunity to change that and to rely on renewable, cleaner sources of energy. The main source of energy for the world should be alternative energy instead of energy from fossil fuels.
