现在对可再生能源的短文

二月18,2012 | By | 2回复 更多

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 安全 从它的威胁来自油“(所罗门1)能源的依赖。 许多人批评是海湾战争和theIraq战争的结果,至少有一部分,我们对石油的依赖。 毫无疑问,许多恐怖组织都可以从那些谁是千亿伊斯兰国家的石油生产国的军事存在不满的同情和支持。 “石油出口国fromSaudi阿拉伯toRussia不仅充电燃料的纪录高油价的美国人,他们也将成为最大的债权国theU.S. 政府“(克鲁格1)。 这设置为其他国家起到了很强的作用,在确定我们的外交政策的阶段。 此外,“油消费者支付美元的4亿美元5,亿元以上的原油每天比他们五年前,抽水石油公司库房2万亿美元以上的石油生产国,仅今年”( mufson 1),这相当于在所有历史的最大的财富转移。 此外,这种财富的巨大转移到国外的美国,肯定是不会帮助我们与我们的严重的经济困境。

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.
