Could Cheaper Oil and Energy Be Dangerous?

In the article titled, “Preserving Ancient Art In Land Marked For Solar Energy Development” by Jeremy Miller, we get a look at the dangers that come along with the benefits of the new fracking industry that has boomed in the US. Cheaper oil and energy seems to be a good thing, but there are prices to pay, including increased carbon in the atmosphere, which only speeds up climate change.  In fact, Figure 1 shows a chart of all the amounts of carbon dioxide emissions by the United States alone. (2)  As you could have guessed from Figure 1, carbon dioxide is the most popular greenhouse gas being released into the atmosphere by humans, harming the environment.

Alternatives would give us a brighter future, but they also come with problems. One example is the BrightSource Ivanpah Solar Power Facility, almost operational on the southern border between California and Nevada. This will be one of the larges utility facilities in the United States, “supplying nearly 400 megawatts of electricity, enough to power 140,000 homes during peak sunlight hours.” (1) This means 400 million joules of electrical energy every second. Compared with fracking, and the damaging pollution that it brings, an array of solar panels seems like a great idea. However, a whole list of issues has come up in the recent months while the solar panels were being installed. For example, the air around an active solar panel becomes heated. A large array of panels can create a “solar flux” (1), which is a pocket of super heated air that could rise and kill birds. This utility is built in the remote Mojave Desert, and may be endangering a rare species of desert land tortoise. This article shows that there is no easy answer to our energy needs. Even though peak energy consumption dropped off slightly after the 2008 recession, our country still needs to find clean, new, and efficient sources of energy that will have minimal impact on the environment. 

I always assumed that solar energy was good, and I was surprised at how many problems were arising from one energy plant. Another one that really struck me was the cultural impact: the land contains some ancient rock art from early Aztec people. Now the archeology is endangered. The descendants of those first natives still live in the area, but their communities are cut across by the array, and some of their native languages, which are only spoken by a handful of people today, are also now endangered by the solar panels. The result is that any new source of energy comes with problems, and these problems and issues need to be weighed against each other.
