One of the earliest ways to harness power is to use the powerful flow of water. On September 30th, 1882, in Appleton, Wisconsin, the first ever dam was built. Since then, over 2,044 billion-kilowatt hours have been produced each day, worldwide. This source of energy is being used more and more ...

A Primitive Resource: Solar Energy and Its Many Uses Ever since the dawn of time, the sun has been a resource we cannot live or do without, so its not such a shock that man has come up with the idea of solar energy. Solar energy had many uses. Some can be dangerous and some, a very valu...

Global Warming Human kind has entered a brand new relationship with the earth. The constant and increasing pressures we are exerting threaten our planets ability to sustain life itself. Change-in the way we think , and in the way we live-is needed now. Global warming is the most urgent envi...

Sources of Energy Have you ever thought about how we get the energy to run the things we take for granite every single day. There are many sources of energy that that are used for transportation, heat, light, and the manufacturing of goods of all kinds. The development of scie...

The world's scientific experts agree that industrial and land use activities are having an adverse impact on our climate. Burning of fossil fuels such as coal, oil, and gasoline creates global warming pollution that acts as the glass in a greenhouse, reflecting heat back toward the Earth and warming...

Alternative Solution for Hawaii=s Future Source of Energy OTEC What would life in Hawaii be like without energy? We would have no lights, no refrigerators, no TVs, no VCRs, no gas. We would have to do without automobiles, airplanes, banks, movies or mail. Imagine Hawaii with no cooking, no ...

Since the discovery of petroleum in the 1860s, fossil fuels have become the foremost source of power in the world. For over a century after their inception, their availability was very seldom called into question. The oil crisis of 1973, however, brought this issue to the forefront. With the widespr...

BIOFUEL - TODAY'S NEED In today's world day in and day out we see fleets of cars, buses, two-wheelers and trucks on our streets. Poisonous fumes damaging our lungs, noise pollution deafening our ears and harried commuters fed up with their lot. Is this what mankind has come to? Imagine ...

Technology vs. Environment In today's world, humans are in a very relaxed cycle: they eat, they watch television, they sleep. What most people do not realize are the health risks they are taking every day when they do their daily tasks. Humans are becoming more and more reliant on machines ...

Hydrogen: The Energy Source of the Future There have been many stories in the newspapers, on TV and on the radio about the state that our planet is in, and most of the time they are not too positive. We hear about pollution, and global warming most frequently, which are both caused mainly by the...

According to the Solar Energy Industries Association reports there was a 67% increase in the solar industry from 2009 to 2010 in the United States. In addition to 67% sales increase, the U.S. solar equipment was installed in 2010 a total capacity of 956 megawatts, and the same year, a total generati...

In 1973 OPEC held the world hostage. They arbitrarily put the world in gasoline crisis causing everyone to come to a complete stand still. One of the outcomes of the oil crises of the seventies is that the United States decided that they could not put all of our "fuel" eggs into one &quo...

Energy is one of the most fundamental qualities in our lives. Almost everything in the world is run by energy. We need electricity to turn on the lights, gas to power our cars, and energy to give us heat to warm our homes. Today, we are totally dependent on an abundant and inexhaustible supply of...
