Non-renewable energy comes from sources that will at some point run out, such as oil and coal.
You are watching: Which of the following best describes the long-term impact of using a renewable energy source?
Non-renewable energy originates from sources that will run out or will not be replenished in ours lifetimes—or even in many, many lifetimes.
Most non-renewable power sources room fossil fuels: coal, petroleum, and natural gas. Carbon is the main aspect in fossil fuels. Because that this reason, the time period that fossil fuels formed (about 360-300 million years ago) is dubbed the Carboniferous Period.
All fossil fuels created in a similar way. Numerous millions of years ago, even prior to the dinosaurs, planet had a various landscape. It was extended with wide, shallow seas and swampy forests.
Plants, algae, and also plankton flourished in these old wetlands. They absorbed sunlight and created energy through photosynthesis. As soon as they died, the biology drifted to the bottom that the sea or lake. There was energy stored in the plants and animals when they died.
Over time, the dead plants to be crushed under the seabed. Rocks and other sediment piled on height of them, producing high heat and pressure underground. In this environment, the plant and animal remains ultimately turned into fossil fuels (coal, natural gas, and petroleum). Today, there are huge underground pockets (called reservoirs) of this non-renewable resources of power all over the world.
Fossil fuels space a valuable resource of energy. Lock are relatively inexpensive to extract. Castle can also be stored, piped, or shipped all over in the world.
However, burn fossil fuels is harmful because that the environment. As soon as coal and oil are burned, they release particles that have the right to pollute the air, water, and also land. Few of these particles are recorded and collection aside, but many the them room released right into the air.
Burning fossil fuels additionally upsets Earth’s “carbon budget,” i beg your pardon balances the carbon in the ocean, earth, and also air. As soon as fossil fuels room combusted (heated), they relax carbon dioxide right into the atmosphere. Carbon dioxide is a gas that keeps warmth in Earth’s atmosphere, a procedure called the “greenhouse effect.” The greenhouse impact is necessary to life on Earth, however relies ~ above a balanced carbon budget.
The carbon in fossil fuels has been sequestered, or stored, underground for countless years. By removing this sequestered carbon indigenous the earth and releasing it right into the atmosphere, Earth’s carbon spending plan is out of balance. This contributes to temperatures rising much faster than organisms can adapt.
Coal is a black color or brownish rock. We burn coal to develop energy. Charcoal is ranked depending on how lot “carbonization” it has actually gone through. Carbonization is the process that old organisms experience to become coal. Around 3 meters (10 feet) of heavy vegetation crushed together right into .3 meter (1 foot) that coal!
Peat is the lowest rank of coal. It has gone with the least amount that carbonization. The is an essential fuel in areas of the people including Scotland, Ireland, and Finland.
Anthracite is the highest rank of coal. Anthracite develops in areas of the people where there have actually been large movements that the earth, such together the development of hill ranges. The Appalachian Mountains, in the eastern component of the unified States, are rich in anthracite.
We mine coal out of the ground therefore we have the right to burn it for energy. There room two ways that we deserve to mine coal: secret mining and also surface mining.
Underground mining is provided when the charcoal is located below the surface of the Earth, sometimes 300 meter (1,000 feet) deep—that’s depth than most of the great Lakes! Miners take an elevator down a mineshaft. Lock operate heavy machinery that cut the coal the end of the Earth and brings it over ground. This can be attention work since cutting coal have the right to release dangerous gases. The gases can reason explosions or do it hard for miners to breathe.
Surface mining is supplied when the coal is located really near the surface ar of the earth. To get to the coal, providers must an initial clear the area. They take far the trees and soil. The coal can then be cut out of the ground more easily. Whole habitats are ruined during this process.
About fifty percent the electrical energy in the unified States originates from coal. It offers power come our lights, refrigerators, dishwashers, and also most other things us plug in. Once coal is burned, it pipeline “byproducts” that are additionally valuable. We usage the byproducts to do cement, plastics, roads, and also many other things.
Coal is a reliable source of energy. We deserve to rely on that day and also night, summer and also winter, sunshine or rain, to administer fuel and electricity.
Using charcoal is additionally harmful. Mining is among the many dangerous work in the world. Coal miners are exposed to toxicity dust and face the dangers of cave-ins and explosions at work.
When coal is burned, the releases many toxic gases and pollutants into the atmosphere. Mining because that coal can also cause the floor to cavern in and create secret fires that burn for decades at a time.
Petroleum is trapped by underground absent formations. In part places, oil bubbles right out of the ground. At the LaBrea Tar Pits, in Los Angeles, California, huge pools of special oil balloon up through the ground. Remains of animals that got trapped there thousands of years back are still preserved in the tar!
Most the the world’s oil is still deep under the ground. Us drill with the planet to accessibility the oil. Some deposits are on land, and others room under the ocean floor.
Once oil companies start drilling through a “drill rig,” they deserve to extract petroleum 24 hours a day, seven days a week, 365 days a year. Plenty of successful oil sites create oil for around 30 years. Sometimes they can develop oil for much longer.
When oil is under the ocean floor, providers drill offshore. They must develop an oil platform. Oil communication are several of the biggest manmade structures in the world!
Once the oil has been drilled, it need to be refined. Oil includes many chemicals besides carbon, and also refining the oil takes few of these chemistry out.
We use oil for many things. About half of the world’s petroleum is converted into gasoline. The rest deserve to be processed and also used in liquid commodities such as nail polish and also rubbing alcohol, or solid products such as water pipes, shoes, crayons, roofing, vitamin capsules, and also thousands of various other items.
There are benefits to drilling because that oil. It is relatively inexpensive to extract. That is likewise a reliable and also dependable source of energy and money because that the regional community.
Oil provides us with thousands of conveniences. In the form of gasoline, the is a portable resource of power that gives us the power to journey places. Petroleum is also an ingredient in numerous items the we depend on.
However, burning gasoline is harmful come the environment. That releases hazardous gases and also fumes into the waiting that us breathe. There is likewise the possibility of an oil spill. If there is a difficulty with the drilling machinery, the oil deserve to explode the end of the well and also spill into the ocean or bordering land. Oil spills are eco-friendly disasters, particularly offshore spills. Oil floats on water, so it deserve to look prefer food to fish and ruin birds’ feathers.
Natural gas is one more fossil fuel the is trapped secret in reservoirs. The is mostly consisted of of methane. You may have actually smelled methane before. The decomposing material in landfills additionally release methane, which smells like rotten eggs.
There is therefore much organic gas underground that it is measured in million, billion, or trillion cubic meters.
Natural gas is discovered in deposits a few hundred meters underground. In order to gain natural gas out of the ground, companies drill right down. However, organic gas walk not kind in huge open pockets. Natural gas is trapped in rock formations that deserve to stretch for kilometers.
To reach natural gas, some service providers use a procedure called “hydraulic fracturing,” or fracking. Hydraulic way they usage water, and fracturing means to “split apart.” The procedure uses high-pressure water to break-up apart the rocks underground. This releases the herbal gas that is trapped in absent formations. If the absent is also hard, they have the right to send acid under the well to dissolve the rock. They can additionally use small grains that glass or sand to prop open up the rock and also let the gas escape.
We use natural gas because that heating and cooking. Natural gas can also be shed to generate electricity. We rely on organic gas to offer power to lights, televisions, wait conditioners, and also kitchen appliances in our homes.
Natural gas can also be turned into a fluid form, called liquid organic gas (LNG). LNG is lot cleaner than any type of other fossil fuels.
Liquid herbal gas take away up much less space than the gas form. The quantity of natural gas that would certainly fit into a huge beach ball would fit into a ping-pong round as a liquid! LNG have the right to be quickly stored and also used for various purposes. LNG can also be a replacement because that gasoline.
Natural gas is fairly inexpensive to extract, and also is a “cleaner” fossil fuel 보다 oil or coal. When organic gas is burned, it only releases carbon dioxide and water vapor (which space the specific same gases that we breathe out once we exhale!) This is healthier 보다 burning coal.
However, extracting natural gas can cause environmental problems. Fracturing rocks can reason mini-earthquakes. The high-pressure water and chemicals the are required underground can likewise leak to various other sources of water. The water sources, provided for drinking or bathing, can become contaminated and also unsafe.
Fossil fuels space the leading non-renewable energy sources about the world. There room others, however.
Nuclear energy is normally considered one more non-renewable energy source. Although nuclear power itself is a renewable power source, the material used in nuclear power plants is not.
Nuclear energy harvests the powerful energy in the nucleus, or core, of one atom. Nuclear energy is released through nuclear fission, the procedure where the cell nucleus of one atom splits. Nuclear strength plants are complicated machines the can control nuclear fission to develop electricity.
The product most often used in nuclear power plants is the facet uranium. Return uranium is discovered in rocks all over the world, nuclear power plants commonly use a very rare type of uranium, U-235. Uranium is a non-renewable resource.
Nuclear power is a popular method of generating electricity about the world. Nuclear power plants perform not pollute the wait or emit greenhouse gases. They can be built in countryside or urban areas, and do not ruin the environment approximately them.
However, nuclear power is an overwhelming to harvest. Nuclear power plants room very facility to build and run. Many communities do not have the scientists and also engineers to develop a safe and reliable nuclear energy program.
Nuclear energy likewise produces radiation material. Radiation waste can be incredibly toxic, resulting in burns and increasing the hazard for cancers, blood diseases, and also bone decay amongst people who are exposed to it.
Biomass energy, a renewable power source, can likewise be a non-renewable power source. Biomass power uses the energy found in plants.
Biomass power relies top top biomass feedstocks—plants that are processed and burned to produce electricity. Biomass feedstocks have the right to include plants such together corn or soy, as well as wood. If human being do no replant biomass feedstocks as fast as they usage them, biomass power becomes a non-renewable energy source.
Fossilized EnergyAccording to the main Intelligence Agency, the human being generates an ext than 66% that its electrical power from fossil fuels, and also another 8% from atom energy.
most valuable form of coal, comprise high carbon content. Likewise called tough coal, black coal, and rock coal.
crop, residue, and also other organic product that can be offered to create energy top top an industrial scale.
greenhouse gas developed by pets during respiration and also used by plants throughout photosynthesis. Carbon dioxide is also the byproduct of burning fossil fuels.
process usually offered to extract oil and natural gas in i beg your pardon fractures in the Earth"s surface room opened and also widened by injecting water, chemicals, and also sand in ~ high pressure. Also called hydraulic fracturing.
phenomenon wherein gases enable sunlight to get in Earth"s atmosphere yet make it daunting for warmth to escape.
gas in the atmosphere, such together carbon dioxide, methane, water vapor, and also ozone, that absorbs solar heat reflected through the surface ar of the Earth, warming the atmosphere.
(liquified organic gas) herbal gas that has actually been cooled and also liquified because that ease in storage and also transportation.
energy resources that are exhaustible family member to the human life span, such as gas, coal, or petroleum.
large, elevated framework with facilities to extract and process oil and also natural gas native undersea locations.
layers of partly decayed essential material uncovered in some wetlands. Peat deserve to be dried and burned together fuel.
process through which plants rotate water, sunlight, and also carbon dioxide right into water, oxygen, and straightforward sugars.
byproduct of nuclear fission the emits a form of heat, or radiation, the can damages the organization of life organisms.
