For the first concept presented above, for conventional renewable energy sources, they are replenished by sunlight or radiation from Earth’s interior; one is fusion, and the other is fission. For so-called non-renewable energy sources, such as hydrocarbons and fissile materials, they are either renewed on timescales so vast that they are effectively non-renewable for humans (such as ), or are “renewed” by the (fissile materials), so could only be renewed with new planetary formation. In mainstream thought, the currently non-renewable energy resources are primarily hydrocarbons (petroleum, coal, and natural gas) and uranium. Much of the debate centers around the definition of oil. What has been called oil for the past 150 years is today called . It is the oil formed by the , and can be mined by drilling wells and extracting it with the conventional methods that have been used since the beginning, and new techniques are periodically invented to increase the rate and total extraction. For conventional oil, humanity has unearthed about 1.1 trillion barrels since 1859, and about as of 2014. Production of conventional oil peaked in 2006 at 25 billion barrels per year and has declined since then. At current production rates, conventional oil will be completely depleted in less than 50 years. About another five billion barrels per year are called unconventional oil, which is called heavy oil, extra heavy oil, and oil sands. Those unconventional oils comprise trillions more barrels, and total and arguably more. For fissile materials, primarily uranium, the peak may have already been reached by 2014, or it . For , in that the peak may have already been reached, or it is only a few decades into the future at most. For coal, may also be only a few decades into the future. Peak extraction usually occurs when about half of the recoverable energy resource has been mined. In summary, the energy resources that have powered the Industrial Revolution are all on their way to largely vanishing in this century. The only resources with seeming viability past this century are coal and unconventional oil, which brings us to the second concept: .
My Past Present and Future Life - Essay by Justblessd2
Economics is the study of humanity’s material well-being, but humans have rarely thought past their immediate economic self-interest, even when the long-term prospects were obviously suicidal, such as today’s global energy paradigm. Because environmental issues affect humanity’s material well-being, they are economic in nature. As can be seen so far in this essay, there was little awareness or seeming caring in early civilizations whether they were destroying the very foundations of their civilizations. Even if they did not care how much other life forms suffered, they did not seem to realize that it also meant that those oppressed and exterminated organisms and wrecked environments would not provide much benefit to humanity in the future, especially energy, whether it was food or wood.
Past, Present, Future - Term Paper
In the "after" that she is living in, Stella is successful enough to support herself and her Aunt Rosa. Even though Rosa believes that Stella "was cold" and "had no heart," she calls her "Dear One, lovely, beautiful; she called her Angel; she called her all these things for the sake of peace" (15). Stella has earned words of adoration, even if they are insincere, from Rosa because of her support. In addition to working to support herself, Stella "took psychology courses at the New School at night, looking for marriage among the flatulent bachelors in her class" (31). Even if her schooling is more of an attempt to meet a future husband than it is to broaden her own education, Stella is at least taking steps to improve her life. In short, Stella becomes "an ordinary American, indistinguishable" (33). Rosa calls her this as an insult, but it still displays the amount of success that Stella has had in moving on with her life. Rosa goes on to say, "No one could guess what hell she had crawled out of until she opened her mouth and up coiled the smoke of accent" (33). Stella has moved on from the Holocaust that people cannot even recognize her as one of its survivors. The only thing she has linking her to the past is her accent. Her Americanization even spreads to her handwriting. Rosa tells us that "Stella's handwriting, pretending to be American, leav[es] out the little stroke that goes across the 7" (39). This thorough Americanization, along with her success, are signs that Stella has moved on from the Holocaust and is able to live in the present.
