With all the hot debate and politics surrounding energy and energy resources, it is important to have a clear understanding of the basics. Once you have a firm foundation of the essentials you will better be able to make informed and educated choices concerning how you use energy. You also will be able to support or disagree with issues raised by political leaders that can affect the publics care of the environment.
In the United States as well as most countries world wide, fossil fuels are used to meet the majority of energy needs. So what are fossil fuels? Simply, coal, oil (or petroleum), and natural gas. These sources of energy are referred to as “fossil” fuels due to the fact that they were created over millions of years from the organic remains of prehistoric animals and plants. Before the age of the dinosaurs, the earth was covered with swampy lands filled with trees. As the trees died and fell into the swamps, they began to be covered with layers of sand and clay. This created sedimentary rock which increasingly layered over the decaying plant life. As it layered, the rock squeezed out the water from the decay, leaving what we consider fossil fuels.
Considering the creation process of these fossil fuels, it is understandable why they are considered “non-renewable” sources of energy. It would take longer than humanity has existed for these fuels to be created again. So unless, humanity wants to wait around for millions of years, for more coal, oil, or natural gas, we must address the problem of our energy resources.
It is reported that the world has doubled its use of fossil fuels every 20 years dating back to the first of the 20th century. This means that we are using up the reserves of fuels available at an increasing rate. It is necessary for the safety of the environment to start looking for other renewable sources of energy.
