Semantically fossil fuels are a renewable source of energy, however given that it takes millions of years for the organic materials to be broken down and converted, it is wholly unrealistic to consider them as renewable. As the demand for fossil fuels increases and source diminish faster than they are replentished, the United States must work towards a renewable energy independent state using truly renable sources, both technically and in practice. With changes in the home, as consumers in buying goods and with alternative fuel sources backed by public trust and governmental involvement, the United States could drastically lessen its dependence on fossil fuels, foreign and domestic. The greatest impact on reducing dependence on fossil fuels could begin at home. All around us are devices that consume energy even as we do nothing with them. Known colloquially as “vampire power”, these devices in standby power mode continue to consume energy as they are never actually “off”. Studies by Ross and Meier (2001) have shown that the average household can have up to 40 different devices consuming energy, from clocks to microwaves and DVD players to television, these devices add up to, between, 5% and 26% of the total electricity consumption in a household – energy likely produced at the cost of burning fossil fuels, both in production of the electricity and the transportation of the fuels themselves. For new or retrofit construction, every choice can lead to energy savings; energy that is derived primarily from fossil fuels. The typical household LED replacement for a 60w light lasts about 50,000 hours. Pretending that an incandescent could also last that long, it would consume about 3,000 kilowatt-hours (kWh) of energy whereas the LE... ... middle of paper ... ...rn, M., Ramroth, L., & Lovins, A.

The reliance on other countries for fossil fuels that produce energy have put the United States of America at risk of being pulled into unstable regions around the world jeopardizing international relationships and putting its own citizens in harm’s way. America needs to balance both the pursuit of alternative energy solutions and reduce energy usage. Our military runs on fossil fuels produced by other nations who do not have similar interests or values as the United States, ultimately adding unwanted risk that becomes difficult to manage. There are advantages to alternative energy solutions that could allow for America to become an independent energy nation that would eliminate the need to support and stabilize various regions around the world. The U.S. Military needs to reduce its overall energy usage by taking advantage of breakthrough technologies that could be integrated onto current systems.
Based on Laurel Nesbit, a program assistant in the Office of Sustainability here at UF, our campus manages to utilize 470,000 Megawatts of energy annually. This figure is generated from all the energy-consuming gadgets that operate on our campus on a daily bases. These gadgets include computers that are left turned on over the night even they are not in use, copiers, and the fume hoods in our laboratories. Admittedly, the success and the health of wellbeing of the students is contingent upon some of these equipment. For instance, the laboratories need the fume hoods in order to keep the experimenters safe. Instead of casting these necessities away, we can develop alternatives which will be capable of generating energy in order to compensate for the electricity that we endlessly
Why People still use inefficient incandescent light bulbs, Jolie Lee, December 27, 2013 retrieved from http://www.usatoday.com/story/news/nation-now/2013/12/27/incandescent-light-bulbs-phaseout-leds/4217009/
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. There are many alternatives to these all but outdated fuel sources.
This project investigates alternative fuel source cars, such as Biodiesel, Hydrogen Fuel Cell, Natural Gas, Ethanol (e85), and Hybrid. I choose this topic when I realized how much people are paying for a fuel (gasoline) that only gives you 30% efficiency per gallon. This means that for every $100.00 that you spend on gas, you are wasting $70.00.
With the advances in technology today, we are able to produce a variety of energy-efficient products, one of which is the compact fluorescent lamp (CFL). Having come a long way from the energy-absorbing incandescents, CFL is clearly the choice for the future. CFLs potentially could save nonrenewable energy resources and electricity expenses because they are so efficient. When we switch over to the CFL, we no longer have to constantly replace burnt out incandescents because a CFL will last “10 times [longer than] the average life of the longest-lived incandescents” (Petrowski, 1995). In addition, for only 13 to 15 watts of electricity, the CFL delivers the equivalent light of a 60 or 75 watt incandescent bulb, representing an energy savings of about 80% (Luoma, 1991). Therefore, we no longer have to drill more oil or mine more coal because if these energy efficient lights were installed in all U.S. homes over the next 20 years, “the savings in energy would equal the estimated energy content of Alaska’s entire North Slope oil fields” (Miller, 1997). Energy efficient lights could also save U.S. businesses $15-20 billion per year in electricity bills (Miller, 1997). It is evident that the potential benefit for the environment is enormous.
The United States currently relies heavily on coal, oil, and natural gas for its energy. While the price of natural gas per barrel continues to plummet, the United States is constantly seeking new sources of renewable energy. Renewable energy consists of any type of natural resource (solar power, ocean power, wind power, rain, snow, etc.). that naturally and automatically replenishes itself. Renewable energy is important because it is infinite and everlasting, meaning our children and our children’s children will be able to utilize these resources long after we are gone.
Over the last two centuries, humanity has become increasingly reliant on fossil fuels. Over that time, the consequences of constantly burning fossil fuels have accumulated into a threat to industrialized cities. The burning of fossil fuels causes acid rain to shower on cities and ecosystems around the world, tormenting their inhabitants. The increasingly deadly pollution caused by the burning of fossil fuels has caused the deaths of many people around the world by causing respiratory problems. Not only has the pollution worsened, but the supply of fossil fuels is not limitless – as humanity’s reliance increases the supply decreases, and that is all the more reason to break humanity’s reliance on fossil fuels. Fossil fuels should be replaced with cleaner alternatives because fossil fuels cause environmental hazards, are non-renewable, and are detrimental to human health.

According to Professor Chris Rhodes and the latest B.P (British Petroleum) statistical review, the “majority of energy used by humans on Earth is crude oil, accounting for 33% of our total, closely followed by coal at 30%. Natural gas follows at a close third place at 24%; nuclear and hydroelectric at 5-6% each; and the tiny fraction of our overall energy that comes from “renewables”, is just 1.6%.” Based on his research, it can be concluded that we are reliant on fossil fuels for 87% of our total energy. A frightening percentage!
When picking an energy resource for the topic of this paper, I bounced around a lot of ideas. Then it occurred to me that I should write about what I will be living with in about a month. My mom just finished designing and building our earthbag, solar, off-grid house, a four-year endeavor. I will soon live in a place powered by one of the most common alternative energy resources, solar energy, so I should learn more about it. At our new house, we have two stand alone pedestals with six 170W panels on each pedestal, making for a 2040W or 2kW solar system.
The world that we live into today affords us the expectation that the flip a switch will turn the lights on. As populations increase and developing nations undergo dramatic economic growth, this energy demand will only continue to grow. The International Energy Agency (IEA) believes that “the world’s energy needs could be 50% higher in 2030 than they are today” (ElBaradei). Given this projected growth, it is necessary for world leaders must take action to secure the energy supply. Meaning that world leaders need to start seriously considering an alternative to non-renewable energy sources. “In 2012, the United States generated about 4,054 billion kilowatt-hours of electricity. About 68% of the electricity generated was from fossil fuel (coal, natural gas, and petroleum), with 37% attributed from coal” (U.S. Energy Information Administration). The fossil fuels that are used to supply over half of our country’s energy are in finite supply and are increasing in price to astronomical heights.
Fossil fuels are energy that is in the form of coal, oil, or natural gas that comes from organisms from millions of years ago. The cycle to create fossil fuels takes millions of years to form and is therefore considered a nonrenewable resource of energy. Fossil fuels have been the primary source of energy for man ever since the age of machines, but one of “the main problem[s] with fossil fuels is that there is a limited amount of them” (Problem with Fossil Fuel). As countries become more developed, like the United States, they too will become more thirsty and dependent for fossil fuels. “In 2004, America spent approximately $270 billion to fufill its oil need.” and “90% of all transportation is fueled by oil” (Nakaya 10). With the global rate of fossil fuels going up it is inevitable that they are going to run out, forcing countries to choose an alternative energy source. The other huge problem with dependence on fossil fuels is the effect that the emissions have on the climate. Fossil fuels are made of carbon chains and in order for the reaction...
Household energy conservation is a very practical and realistic approach to conserving energy within our society. US households consume a tremendous amount of natural gas as well as electric energy. It has been calculated that the amount of energy consumed within the US increased exponentially from about 1850 to 1975. If energy continued to increase at this rate, we would be experiencing severe energy shortages in our current society. Luckily, steps towards conservation, including various energy regulations, have curbed that growth somewhat, brining the predicted 160 Qbtu/yr for the year 2000 down to around 93.8 Qbtu/yr by the year 1996. However, household energy usage is still a major issue as households consume about 38% of the total consumed energy and contribute greatly to natural gas consumption and issues such as global warming. Therefore, it is important that people understand how we use energy in the household and what steps can be taken to conserve that energy.
Energy Efficiency refers to the use of energy on the same level, performance, comfort, suitability. As the world progress through technologies, more energy is required to power the world through various sources. Society has reached a point of our civilization when electricity is used for all purposes and therefore our presence will be impossible without it. However increasing amount of energy used will lead to numerous social and economic problems. Electricity demand is increasing twice as fast as overall energy use and is likely to rise by more than two-thirds 2011 to 2035. In 2012, 42% of primary energy used was converted into electricity. In the near future, cities will need to become increasingly energy efficient to deal with them. There are three strategies to attain energy efficiency which have their benefits.
