Hybrid Cars and Pollution

Hybrid Cars and Pollution

It may seem excessive to spend so much time and money developing more economical cars as an alternative to gasoline automobiles, especially since the general population seems to be perfectly happy with current automotive technology, but hybrid cars offer another great advantage; far lower emissions.

When emissions or tailpipe emissions are mentioned in a discussion about cars, the terms refer to the gases released by the burning of gasoline that pollute the atmosphere. These gases are Carbon Dioxide, Carbon Monoxide, Nitrogen Oxides, and Hydrocarbons. These gases, commonly referred to as greenhouse gases, are of particular concern, because of their effect on the earth's climate by trapping heat in the atmosphere that would normally be deflected back to space. The National Research Council performed a study in May 2001 on the effects of greenhouse gas.

“Greenhouse gases are accumulating in Earth’s atmosphere as a result of human activities, causing surface air temperatures and sub-surface ocean temperatures to rise. Temperatures are, in fact, rising. The changes observed over the last several decades are likely mostly due to human activities, but we cannot rule out that some significant part of these changes is also a reflection of natural variability.”

Hybrid cars have been accepted as an intermediary solution to the current emissions problems that we face, as they offer lower emissions than gasoline automobiles.
