Fossil fuels are produced by the decomposition of dead organisms, buried for millions of years. They produce greenhouse gasses and other pollutants, and their continued use could leave mankind as extinct as those decayed fossils.
The earth does not hold an infinite amount of these fuels. Barring our extinction, the supply of fossil fuels will eventually run out, though demand for energy never will. An energy source is needed that is both eco-friendly and renewable, something as solar panels are. In other words, one that doesn't pollute, and will never run out. |

What Is "Electricity?" In the most general sense, there is no true definition for the term. The word electricity is impossible to define correctly because it has far too many meanings, each of which contradict one another. This is a confusion that few people are actually aware of. That includes highly technically minded people like scientists, teachers, engineering specialists, electricity suppliers, and even people working for your utility company.

More and more we see dire headlines in the news concerning global warming and the impact it will have on our planet. Our environment is changing, and we may not be prepared to offset all of the consequences. One of the biggest challenges that we face is the reality of "heat islands" created by the concrete and asphalt that make up the streets, parking lots and sidewalks of our major cities. The heating impact of cities is well documented, but what can be done to reduce it? |

The Industrial Revolution began in Britain in the 1700s, and spread to the rest of the world, beginning with the United States. The use of machinery and factories led to mass production, which in turn led to the development of numerous environmental hazards. The effects on the environment would only be seen clearly years later.
The use of factories and mass production has led to a depletion of certain natural resources, leaving the environment permanently damaged. One example of this depletion is deforestation, which is the clearing of forest trees for use in production. When the trees are cleared, the wildlife in the forest also becomes uprooted. |
