Answer:
oil is a expsense thing. meaning the more you have the richer you can become using it.Formed by heat and pressure over hundreds of thousands of years, oil is an energy-rich fossil fuel that impacts nearly every aspect of modern life. Crude oil can be refined into any number of plastics and petroleum products, or turned into liquid fuels like gasoline and diesel.

Fueling a Clean Transportation Future
Oil, electricity, and biofuels are all changing in dramatic ways. Whether they become cleaner or dirtier is up to us.
Extracting and refining oil requires substantial amounts of energy and can lead to profound land, air, and water impacts. When it's then used as a fuel and burnt, oil releases a number of airborne pollutants and toxins. These include smog-forming particles that cause asthma and other health problems, and carbon dioxide, a major heat-trapping gas. In the United States, oil used for transportation is directly responsible for around 30 percent of the nation's global warming pollution.
These and other impacts may worsen as easily-accessed sources of liquid oil dry up. So-called "new" sources of oil—such as tar sands and tight oil—come with new problems. Tar sands require significantly more energy to extract and refine, emitting up to three times more greenhouse gas emissions in the process. Tight oil production can involve extensive flaring, increasing its total pollution. These additional emissions mean that the dirtiest sources of oil can add as much as an extra ton of pollution per year for the average car.
Despite their impacts, unconventional oils account for a rapidly increasingly percentage of oil production. In the United States, tight oil alone increased from 23 percent of domestic production in 2011 to 45 percent in 2013.
But the status quo isn’t guaranteed. Widespread use of cleaner fuels like electricity and biofuels could save around three million barrels of oil per day by 2035: fuel efficiency could save over 5 million. Progress is already being made, with more electric vehicles hitting the roads than ever before, new biofuels facilities opening every year, and historic fuel efficiency standards coming into effect. And while drivers and policy makers support this transition to a cleaner transportation system, oil companies can take steps to ensure that the oil we do use doesn't get dirtier.
