Energy One global issue is conserving energy. Energy is one of the primary things that people must have to go through their everyday lives. However, energy has its negative side. People should find a new source of energy since it is such a necessity in our everyday lives. One reason we shoul...
The Effect of Humans on The Environment AIR The Greenhouse Effect/Global Warming What is it? The greenhouse effect is the rise in temperature that Earth experiences. What causes it? Global warming is an increase in the earth¡s temperature due to the use of fossil fuels...
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...
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...
Physical & Biological Resources The oceans provide modern society with numerous resources. For centuries the ocean has provided humans with things such as food, clothing, shelter materials, and a way of transportation. In today's world more than half of the resources that humans use are deri...
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...
There are many ways to produce electricity but unfortunately not all of them are clean and safe. Luckily here in Canada we have clean and safe alternatives to things like the burning of fossil fuels. We are the largest producer of hydropower in the world. Hydro energy is electricity made using water...

Coal Power Currently America's main source of electric energy is coal, which accounts for 1.97 PW per year or 52% of America's electric energy. We are currently extremely dependent on it for a number of different reasons. Coal is a reliable source of energy. Which is very abundant in th...
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...
We get energy from sunlight, wind, nuclear plants, and damns... However, most of the points that we use come from fossil fuels. There are three primary fossil fuels: coal, oil, and natural gas. These are composed of carbon, hydrogen, nitrogen, oxygen, and sulfur. Carbon is the major element in fossi...
Arctic National Wildlife Refuge The Arctic National Wildlife Refuge was created in 1960 in northeastern Alaska to protect and maintain it's naturally functioning community of arctic and sub-arctic ecosystems. A variety of wildlife, including 36 fish species, 36 kinds of land mammals, over ...
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...
CRUDE OIL Crude oils are unprocessed oils mined straight from the oil source. Crude oils are such a useful starting point for so many different substances because they contain hydrocarbons. Crayons, plastics, heating oil, jet fuel, kerosene, synthetic fibres and tires are all originally made from...
