Un saggio breve su energie rinnovabili Ora

Energy has become an extremely hot topic for Americans over the last couple of years, with reasons for our energy concerns ranging from environmental to political to financial. Despite differing reasons, it is clear that the solution to our energy problems is to transition from traditional energy sources to renewable energy sources, thereby reducing greenhouse gas emissions, ending our dependence on foreign oil, and eliminating our world record transfer of wealth to oil producing nations.

Some scientists claim the global warming we are experiencing is not manmade. There are also critics who argue that renewable energy sources have severe drawbacks, such as having to use natural resources to produce a wind mill, or using large amounts of land to host massive quantities of solar panels. There are even those who believe that we are not in danger of depleting our traditional energy sources such as oil since although the cost of oil has increased, it is not severe enough to indicate there is a problem.

The necessity of reducing greenhouse gasses has been around for years. There are opponents of global warming who claim XCHARXthe global warming that we are experiencing is just the result of natural cyclesXCHARX (‘Is Global Warming a Myth?’ 1) which include periodic increasing and decreasing global temperatures that have occurred over the centuries and millenniums. However, XCHARXa group of 600 leading climate scientists from 40 nations, says it is ‘very likely’ (more than a 90 percent chance) that humans are causing a global temperature change that will reach between 3.2 and 7.2 degrees Fahrenheit by the end of this centuryXCHARX (1). With only a ten percent chance of error that global warming is not taking place, it is prudent we take action.

Our dependence on foreign oil has caused the United Statesmajor problems in the area of national security, and an enormous net transfer of wealth from the United Statesto other countries. According to Mr. Woolsey, former director of the Central Intelligence Agency, “the United Statesfaces a grave national sicurezza minaccia dalla sua dipendenza da energia derivata dal petrolio "(Solomon 1). Molti criticano la guerra del Golfo e theIraq guerra per essere il risultato, almeno in parte, della nostra dipendenza dal petrolio. Senza dubbio, molte organizzazioni terroristiche sono sempre simpatia e il sostegno di coloro che sono scontenti di Stati theUnited presenza militare in nazioni islamiche produttori di petrolio. "Nazioni fromSaudi Saudita toRussia non sono una carica soltanto americani registrare prezzi elevati per il carburante Petroleum esportatori, ma sono anche pronti a diventare il più grande creditore di theU.S. governo "(Kruger 1). Questo pone le basi per gli altri paesi di svolgere un ruolo molto forte nel determinare la nostra politica estera. Inoltre, "i consumatori di petrolio stanno pagando $ 4 miliardi a $ 5 miliardi in più per il petrolio greggio ogni giorno quello che ha fatto solo cinque anni fa, pompando più di $ 2 miliardi nelle casse delle compagnie petrolifere e delle nazioni produttrici di petrolio solo quest'anno" ( Mufson 1), il che equivale al più grande trasferimento di ricchezza in tutta la storia. Inoltre, questo enorme trasferimento di ricchezza fuori degli Stati Uniti in paesi stranieri non è certo intenzione di aiutarci con le nostre difficoltà economiche gravi.

Fortunately, there is a solution. The cost of renewable energy is decreasing. According to a solar energy specialist, XCHARXa big thumbs up for an industry that’s making huge advances in lowering costs and improving efficiency” (Kanter 1). Additionally, XCHARXXCHARX experts advising the United Nations said renewable sources could deliver nearly 80 percent of world’s total energy demand by the middle of the centuryXCHARX (1). Since the cost of oil and other nonrenewable energy sources is increasing, it is rapidly becoming more cost effective to use renewable sources. Although renewable energy technology is quickly advancing, renewable energy sources are not without potential environmental drawbacks such as the large amounts of land required to place solar panels, or the effect placing a dam on a river has on the surrounding area. However, according to President ObamaXCHARXs policy, environmental groups including the Natural Resources Defense Council, National Wildlife Federation, Wilderness Society and Sierra Club all will soon agree with the final plan. This is a strong indicator that plans for building and placement of renewable energy technology have been created with sensitivity towards potential negative environmental issues.

Within our free market American belief system is the fundamental idea that the free market will drive change. At this time, with the American market clamoring to go green, our military fighting terrorism on foreign soil, and the cost of energy being at record highs, the time is right for change. With the rate at which renewable energy technology is advancing and cost effective renewable energy is becoming available, the United States needs to accelerate the transition from traditional energy sources to renewable energy sources.
