3 9.1 Main Energy Sources Non-renewable energy sources are those that are consumed faster than the resources can be replenished. Coal, oil and natural gas (providing about 80% of the world’s energy) renewable energy sources are either self-replenishing or are always present as part of the environment. Solar, geothermal, tidal, etc. Currently, about 12% of the energy used in the world is supplied, mainly from hydroelectric power plants and wood.

A resource is a natural substance for human use that may be extracted using current technology. A resource is a known deposit that can be economically mined using current technology under certain economic conditions. Reserves are less than resources. Inventory levels change due to technological advances, new discoveries, and varying economic conditions. If the cost of fuel removal and processing is higher than the fuel’s market value, no one will produce that fuel. If the amount of energy used to manufacture, refine, and transport the fuel is greater than the energy produced by burning the fuel, no fuel is produced.
Coal 300 million years ago, freshwater swamps covered much of the earth. These wetland conditions caused rapid plant growth, resulting in the accumulation of large amounts of plant material. it was done. As a result of geological changes, some of these deposits were covered by seas and covered with sediments. Over time, pressure and heat transformed organic matter into carbon. Depending on the time and organic material, several different types of coal are produced (peat, lignite, subbituminous, bituminous and anthracite).
Oil and natural gas probably come from microscopic marine organisms that accumulate on the seafloor and are covered by sediment. Decomposition of these organisms released oil droplets. The clayey rocks gradually formed oil-bearing shale (sedimentary rock). Geological conditions (folding or shifting of sedimentary rock formations) create conditions that allow water and gas pressure to push oil and gas out of the shale). If the heat generated on Earth reaches a sufficiently high temperature, natural gas can form along with or instead of oil. Natural gas often forms on the surface of oil.
Coal is the most common fossil fuel, but it provides less than 30% of the energy used. Mainly used for electricity production. There are four categories of coal: lignite, subbituminous, bituminous and anthracite. Lignite (soft, brownish-black coal with more advanced plant material changes than peat but less than bituminous coal). High moisture, low energy, friable and most undesirable form. Sub-bituminous coal (usually dark brown to black coal, rank intermediate between lignite and bituminous coal) Lower moisture and higher carbon content than lignite. It is used as fuel in power plants.

16 Coal Bitumen (black coal, relatively soft, containing a tar-like substance called bitumen) Low moisture, high carbon Used in power plants and other industries such as steelmaking. It is the most used because it is the easiest and most common to mine, covering 20% of the world’s energy consumption. Anthracite (hard) has the highest carbon content and is relatively rare. It is mainly used for heating buildings.
There are two methods of mining. strip mining. The process of removing material above the piston (topsoil) to reach the coal underneath (if the topsoil is less than 100 meters). It is effective but destructive. Underground mining minimizes surface disturbance, but is expensive and dangerous. Many miners suffer from black lung disease. It is a respiratory disease caused by the accumulation of fine particles of coal in the lungs of miners (more than 8% of miners who worked in mines for more than 25 years tested positive).
Mining causes dust pollution. Burning coal releases pollutants (carbon and sulfur). Millions of tons of material are released into the atmosphere each year. Sulfur leads to acid mine drainage and acid fallout. When coal burns, mercury is released into the air. An increase in atmospheric carbon dioxide contributes to global warming. Reduction: Leaves space after carbon is removed. Underground mines can collapse and the ground above them can sink.
22 Oil Oil is more concentrated than coal, burns cleanly and is easily transported by pipeline. These properties predetermine their use in automobiles. Hard to find. Less damaging to the environment than a coal mine.

Once a source of oil is found, it must be extracted and transported to the surface. Primary Extraction Methods If the water or gas pressure associated with the oil is high enough, the oil is forced to the surface during well drilling. If the water and gas pressure is low, the oil will be pumped to the surface. Depending on viscosity and geological properties, 5-30% oil is recovered.
Water or gas is pumped into the well, pushing the oil out of the pores of the rock. This technology allows extraction of up to 40% oil. Tertiary recovery steam is pumped into the well to reduce the viscosity of the oil. Aggressive pumping of gas or chemicals can be pumped into the well. These methods are expensive and are only used when oil prices are high.
Since oil comes from the earth, it is not in a usable form and must be refined. Several products can be made from one barrel of oil. Oil spills from oil spill incidents account for only about one-third of oil pollution from ships (Deepwater Horizon 2010). 60% is due to normal transportation operations.
30 Natural Gas Extracting natural gas is similar to extracting oil. It is difficult to transport and is burned in oil fields in many places, but new transport methods are being developed. Conversion (conversion to liquid) at -126o F (1/600 his volume of gas) Public concern about safety in loading and unloading equipment (potential explosions due to accidents). Therefore, they are located in the sea. It is a fossil fuel with the lowest environmental impact. Almost no air pollution (clean burning). It emits less CO2 than coal or oil.

Difference Between Renewable And Non Renewable Resources
Non-renewable and renewable resources. NON-RENEWABLE RESOURCES Non-renewable resources are natural resources that cannot be regenerated or grown on a large scale.
Chapter 17 Non-Renewable Energy. Part 1: Energy Resources and Fossil Fuels Fuels are mainly used for five purposes. 1. Transport (use of petroleum #1)
NON-RENEWABLE vs. RENEWABLE Sunlight, wind, rain,
Natural resources. Renewable resource: A resource that can be replaced in nature at a rate close to its utilization rate. Oxygen Wood Food Sunlight.
Non Renewable Energy: Coal
Disadvantages Many wind turbines are required to generate enough power. Turbines can only be installed in windy areas. It’s not always windy. Some people don’t.
Non-Renewable Energy: How the Dead Powers Our Lives? Life needs energy – it stores, moves and transforms. The Ultimate Energy Source of Life – The Sun For humans, our energy source is food Fuel – Any substance that can be used for energy Fuel is never 100% efficient – only 5-20% of what is actually consumed is consumed Some energy is lost – some is converted into heat, light and sound energy
ENERGY SOURCE EVALUATION The types of energy sources we use determine our quality of life and the amount of negative impact on the environment.
