INTRODUCTION ...a safe, environmentally sound, and an economically viable energy pathway that will sustain human progress into the distant future... Can this "energy pathway", as called for in the Brandtland Commission in 1987 (Mitchell, 1996: 149), be fulfilled by the current energy situation? ...

Emissions from the tailpipe of the car in front of you, smoke dispersing from a smokestack and forming a black haze around the horizon, or the strange black tint in the water left over from an oil spill years ago. These are all types of pollution and are all caused by one common entity: fossil f...

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 ...

Friends of the Earth say that "up to 24,000 people die every year as a result of air pollution." That is not much of a surprise when there are now around 500 million cars polluting the planet. The problem is that we can't live without cars, because they are part of our daily lives. But, from the ...

Alternate Sources of Electricity: Wind Power Wind is created from an unequal heating of the earths atmosphere therefore wind is an indirect form of solar energy. Convection currents, which occur due to the fact that warm air rises and cooler air drops, produces this cycle of air or wind. Some of th...

1. Population Now the population of the world has reached 6 billion in 2000. And it is estimated to have 10.5~11 billion of population until the population of the world will stabilize.
