WHY DO WE NEED OIL AND GAS?

Oil and natural gas are an important part of your

everyday life. Not only do they give us mobility, theyheat

and cool our homes and provide electricity. Millions of

products are made from oil and gas, including plastics,

5 life-saving medications, clothing, cosmetics, and many

other items you may use daily.

In the United States, 97% of the energy that drives

the transportation sector (cars, buses, subways, railroads,

airplanes, etc.) comes from fuels made from oil. Auto

10 manufacturers are developing cars to run on alternate

fuels such as electricity, hydrogen and ethanol. However,

the electric batteries need to be charged and the fuel to

generate the electricity could be oil or gas. The hydrogen

needed for fuel cells may be generated from natural gas

15 or petroleum-based products. Even as alternative fuels

are developed, oil will be crucially important to assuring

that people can get where they need to be and want to

go for the foreseeable future. Unless there is an increase

in the penetration of new technologies, alternative fuels

20 are not expected to become competitive with oil for

transportation before 2025.

World population is currently around 6 billion people,

but is expected to grow to approximately 7.6 billion by

2020. That will mean a huge increase in the demand for

25 transportation fuels, electricity, and many other consumer

products made from oil and natural gas.

The world economy runs on these fuels. They

improve your quality of life by providing you with

transportation, warmth, light, and many everyday products.

30 They enable you to get where you need to go, they supply

products you need, and they create jobs. Without them,

quality of life would decline and people in developing

nations would not be able to improve their standard of

living.
