Effect of Polluted Air in Our Lives. Air pollution is the most harmful substance to the atmosphere resulting in damage to the environment, human health, and quality of life. It is not only a personal or national problem, but it also has become a global problem. Air pollution mostly occurs from hum...
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? ...
Fuel of The Future Hydrogen, the simplest element, is composed of one proton and one electron. It makes up more than 90% of the composition of the universe. More than 30% of the mass of the sun is atomic hydrogen. It is the third most abundant element in the earth's surface, and is found most...
Modern civilization depends largely on energy. Without it, our lives would be reduced to the level of a caveman's. We would have nothing to power the equipment we rely on to get on with our daily lives. Life would in a way come to a standstill without energy. Without wood, we would not even be able...

When people think of hydrogen, outside the studying of a chemistry class or something to that effect, thinks immediately of the hydrogen bomb. This situation is obvious a big image problem. Thanks to new technology, hydrogen has escaped the imagine of the unbearable to other more economical thoug...
Global warming is one of the foremost problems facing our planet today. As pollution rises the ozone layer breaks down, and as the temperatures go on a constant rise glaciers and ice-caps melt. Many people have their doubts about the global warming "theory", however proof of this "t...

This article talks about how the hydrogen economy will be coming. There are a lot of obstacles that they must surpass to form a hydrogen economy. In the year 2003, President George W. Bush announced a 1.7 billion research program to develop a vehicle that would make the air cleaner and use less oil...
As the scientific world progresses and the over-consumption of fossil fuels continues, scientists, environmentalists, and businessmen alike seek alternate forms of energy production and usage. One such alternative is viable through fuel cells. Fuel cells can power cars, trucks, and buses without emi...
Introduction The environment of planet earth is heavily dependent on a stable climate. The stability of this climate has been continually compromised since the beginning of the industrial revolution. Poor pollution controls and the ever-increasing human industrial activity are causing...
With the earth's precious natural resources being used up and the pollution from our great use of fossil fuels, many nations and communities have turned to the use of an alternative energy sources. Among those alternative energy sources is the use of tidal waves and currents to generate electri...
Global warming is an increase in the earth's temperature due to fossil fuels, industry, and agricultural processes caused by human, natural, and other gas emissions. This results in an increased emission of greenhouse gases. Short-wave solar radiation sinks into the Earth's atmosphere and warms it...
