ENERGY RESOURCES Fossil Fuels At the end of this lesson, you should be able to: cite examples of fossil fuels; trace how fossil fuels are formed; compare and contrast coal and oil; and cite uses of fossil fuels and its environmental concerns. Our planet earth, aside from its distinctness from other planets due to inhabitation of human and other life forms, is blessed with the bounty of its natural resources. From its abiotic resources (water, air, soil, land, minerals, etc.) to its biotic resources (plants, animals, etc.), it can be said that living in this planet is a blessing. Earth provides vast amount of resources for human needs and consumption, for its survival and advancement. Try to look at your surrounding? Do you know what they are made of? Look at the things inside your home. Can you site the materials needed and where they came from? Everything comes from the resources that the earth possesses. You may notice that most of the materials used in your home came from abiotic resources, from your gadgets to your appliances. ENERGY RESOURCES Energy Resource refers to any material that can be used as a basis or source of energy. Examples: Nuclear energy, fossil energy -- like oil, coal and natural gas -- and renewable sources like wind, solar, geothermal and hydropower. FOSSIL FUELS Fossil fuels are source of energy derived from the fossilized remains of once living plants and animals million years ago. FOSSIL FUELS Those remains of dead plants and animals long time ago were buried and fossilized in the earth’s crust, thus this fuels are found beneath the earth’s surface. Since this fuel originated from the remains of once living organisms, fossil fuels composed mainly of high content of carbon and hydrogen, called hydrocarbons. FOSSIL FUELS Fossil fuels includes coal, oil (includes petroleum or crude oil) and natural gas. COAL Coal is a type of fossil fuel that is non-renewable source of energy. It is a solid rock form of fossil fuel that originated from the dead plant and animal matter that piled up in layers for over million years ago. Its material is highly composed of carbon content. COAL Coal can be extracted using two methods: surface mining and underground mining. Surface mining, also known as strip mining, involves the removal of the entire layer of rock and soil to access the coal deposit beneath the surface. Underground mining involves the usage of heavy machinery to cut coal from deep underground deposits. OIL Oil/Crude oil or also known as Petroleum is another type of fossil fuel that is non- renewable. It is a liquid type of fossil fuel composed mostly of hydrocarbons. Like coal, petroleum originates from the remains of living organisms. OIL Petroleum comes from ancient marine organisms like marine plants, algae and bacteria. This can be extracted by drilling on land or at sea. It can also be extracted through strip mining in the case of tar sands oil and oil shale. OIL Once extracted, this oil will be transported to refineries to transform oil into usable fuels like propane, kerosene, gasoline and other fuel products. Also it is used in making plastic and paint products. NATURAL GAS Natural gas is a type of fossil fuel that is odorless, colorless hydrocarbon gas. It made up of hydrocarbon that is mostly methane (CH4). Natural gas, like other types of fossil fuels, is originated from the remains of plants, animals, microorganisms that once lived millions of years ago. NATURAL GAS If a natural gas is found in porous and permeable rock beds or mixed into oil reservoirs which can be extracted through drilling, this is called conventional natural gas. On the other hand, unconventional natural gas are those that are too difficult or expensive to extract and require a special stimulation technique like fracking. Process of formation of the different types of fossil fuels is almost the same. They both originated from the remains of living organisms that lived millions of years ago. However, coal formed from vegetation while oil came from marine organisms. Over millions of years, the remains of these organisms were buried deeper beneath the earth’s surface as time passes by. As the remains buried deeper, it will experienced extreme heat and pressure beneath. Due to high pressure and temperature, this will result to the formation of fossil Nowadays, these fossil fuels are drilled and extracted for human used. Coals are fuelled in power plants to generate electricity. Oils are refined and transformed into usable fuel like gasoline that fuels your engine. Natural gas is now used for fuel and a source of energy for electricity. SUMMARY 1. Fossil fuels are source of energy derived from the fossilized remains of once living plants and animals million years ago. 2. Fossil Fuels are non- renewable type of energy resource. 3. Fossil fuels are composed of hydrocarbons. SUMMARY 4. There are three types of fossil fuels: coal, oil and natural gas. 5. Coal is a solid rock form of fossil fuel that originated from the dead plant and animal matter that piled up in layers for over million years ago. 6. Oil also known as petroleum, is a liquid type of fossil fuel composed mostly of SUMMARY 7. Natural gas is a type of fossil fuel that is odorless, colorless hydrocarbon gas. And is made mostly of methane (CH4). 8. Fossil fuels are commonly used as energy to power engines and other materials at home and industries for these to work. 9. Fossil fuels as non-renewable source of energy have disadvantages and could impact negatively to the environment especially during its combustion since it produces carbon dioxide and other greenhouse gases.
