The term automobile, which is also known as motorcar, is a broad word that refers to a variety of vehicles. It can be a car, truck, or van. These vehicles are designed for passenger transportation, and usually have an internal combustion engine.
Automobiles are important parts of society. In 1990, there were 630 million motor vehicles on the road worldwide. Approximately twenty million people rely on motorized vehicles for their livelihood.
The automotive industry has a significant impact on the environment. It uses gasoline, natural gas, coal, and steam, and it consumes a great deal of raw materials.
Automotive manufacturing has been one of the most influential engines driving the U.S. economy. It is the biggest purchaser of iron and steel, aluminum, and lead for batteries.
As the automobile industry has grown, so has its impact on the environment. Today, the automotive industry is one of the largest consumers of energy in the U.S. This is largely because of the large amount of energy it requires to extract raw materials from the earth.
The automotive industry also produces a lot of waste products. A study estimates that the fabrication of one car produced approximately 29 tons of waste.
One of the most common sources of emissions from vehicles is exhaust fumes. These pollutants cause eye irritation, reduce visibility, and are a source of secondary pollutants.
To address the problem, the automobile industry has spent considerable funds on research and development. It has developed emission control systems, and it has improved the drivetrains and safety systems of its vehicles.
