At this juncture, I will ask my readers to perform an exercise that I first saw described by Peak Oil advocate , which is to lay aside data and graphs and just think about how energy makes everything in our daily lives possible. Think about your food, water, mode of transportation, and materials that comprise your home and possessions, and think of the role that energy played in providing them. Think about the energy that you use each day in powering your home and in your transportation, even if it is just walking. Then imagine running out of energy. When you flipped on a light switch, nothing happened. When you turned on the tap, no water came out. Your refrigerator stopped working, food deliveries to your community ceased, and no electricity, oil, gas, coal, or even wind or water power was available. Everything in your life would come to a sudden halt. When people have tried to demote energy below spirituality, social relations, or even made it irrelevant to economics, my question is for them to see what they can forego the longest: prayer/meditation, social interaction, sex, or energy. The fossil fuels burned to power industrial civilization provide several hundred energy slaves for each American and no less than hundreds per person in every industrialized nation. All that those energy-leveraged humans do is direct the energy, like holding the reins of a gigantic beast that each person rides each day. Airline pilots half-joke that they begin their workday by strapping jet airliners to their waists. Without that energy to direct in the myriad ways that industrialized humans use it, modern civilization would come to an abrupt end.

When oil spills into the ocean, it is difficult to clean up. When you have 3.19 million barrels to clean up, it is even harder.

The most basic method of clean up is to control the spread of the oil using physical barriers. When oil spills in water, it tends to float to the surface and spread out, forming a thin slick just a few millimeters thick. (A very thin slick is called a sheen, which often looks like a rainbow and can be seen in parking lots after a rainstorm.) Cleanup workers first surround the slick with to harbors, beaches or biologically important areas like marshes. Then they can use different tools to remove the collected oil. Often they will drive skimmers, boats that skim spilled water from the water's surface, through the slick.

Dr. Chris Reddy, an environmental chemist from Woods Hole Oceanographic Institution, studies oil spills and their long-term impacts.

Part of the difficulty is that no two spills are alike. The amount and type of oil (whether crude or refined) affects how it spreads, and a spill in seawater spreads differently than freshwater. Local environmental conditions also play a huge role: currents, tides, weather, wind speed and direction, air temperature, water temperature and presence of ice all affect how the oil spreads and how well cleanup workers can access the spill area. This variability makes it difficult to plan for spills ahead of time.

The Deepwater Horizon Oil Spill | Accurate Essays

After most of the oil is removed by skimmers, workers use sorbents to mop up the trace amounts left behind. either absorb oil like a sponge or adsorb oil, which means that oil sticks to its surface. They come in three main types: natural organic materials like peat moss, straw, hay and sawdust; natural inorganic materials like clay, volcanic ash, sand, or vermiculite; and synthetic sorbents made of materials similar to plastic like polyurethane, polypropylene, and polyethylene. Which type is used will depend on the particular spill, as some types of sorbents work best on different types of oil and under different weather conditions.

Removing spilled oil from the environment is a difficult task. Because oil is hydrophobic (doesn't mix with water), it floats to the surface when it spills into the ocean and forms large slicks. These slicks can wreak havoc on coastal ecosystems and animals, so cleanup workers use —chemicals that break down the oil into smaller particles that mix with water more easily—to prevent them from forming. Evaporation and bacteria can then degrade these tiny droplets more quickly than if they were in a large slick, or waves can wash them away from the spill site.
