Fossil Fuels and The Current Energy Crisis (3rd Grading-No.1)

Fossil fuels, coal, oil and natural gas, are a non-renewable source of energy. Formed from plants and animals that lived up to 300 million years ago, fossil fuels are found in deposits beneath the earth. The fuels are burned to release the chemical energy that is stored within this resource. Energy is essential to modern society as we know it. Over 85% of our energy demands are met by the combustion of fossil fuels.

Going back to the earlier days of Earth, the plants and animals that lived then eventually died and decomposed. The majority of these life forms were phytoplankton and zooplankton. When these ancient ocean dwellers died, they accumulated on the bottom of a seabed; this is how a good portion of our fossil fuel reserves began. The actual transformation process of these prehistoric creatures is not known, but scientists do know that the pressure, heat, and a great deal of time go into the making of fossil fuels.

Fossil fuels are excellent sources of energy for our transportation needs; however they are also the primary source of electrical energy in the world today. Coal power plants account for at least 52% of the world's demand. We, as a world, burn approximately 1.9 billion tons of coal a year to generate electricity.

We are currently in an energy crisis. Fossil fuels are the lifeblood of our society and for many others around the world. Our supply has a finite end. Fossil fuels will run out and the use of them will soon take the lives of many people. These are important reasons to find other means of getting the energy we need to continue our society as we know it.

So what are our options?
