Non-renewable energy comes from sources the will eventually run out, such together oil and also coal.
You are watching: Which of the following best describes the long-term impact of using a renewable energy source?
Non-renewable energy comes from sources that will run the end or will not be replenished in ours lifetimes—or even in many, numerous lifetimes.
Most non-renewable power sources space fossil fuels: coal, petroleum, and natural gas. Carbon is the main aspect in fossil fuels. For this reason, the time period that fossil fuels developed (about 360-300 million years ago) is referred to as the Carboniferous Period.
All fossil fuels created in a similar way. Thousands of millions of years ago, even before the dinosaurs, planet had a different landscape. The was spanned with wide, shallow seas and also swampy forests.
Plants, algae, and plankton flourished in these ancient wetlands. They soaked up sunlight and also created energy through photosynthesis. Once they died, the biology drifted to the bottom of the sea or lake. Over there was energy stored in the plants and animals when they died.
Over time, the dead plants were crushed under the seabed. Rocks and other sediment piled on peak of them, creating high heat and also pressure underground. In this environment, the plant and animal remains at some point turned into fossil fuels (coal, organic gas, and petroleum). Today, over there are huge underground pockets (called reservoirs) of these non-renewable resources of power all end the world.
Fossil fuels room a valuable source of energy. Lock are relatively inexpensive to extract. They can likewise be stored, piped, or shipped everywhere in the world.
However, burn fossil fuels is harmful because that the environment. Once coal and also oil are burned, they release particles that have the right to pollute the air, water, and land. Several of these corpuscle are recorded and collection aside, but many that them are released into the air.
Burning fossil fuels likewise upsets Earth’s “carbon budget,” i m sorry balances the carbon in the ocean, earth, and also air. When fossil fuels space combusted (heated), they release carbon dioxide into the atmosphere. Carbon dioxide is a gas the keeps warm in Earth’s atmosphere, a process called the “greenhouse effect.” The greenhouse effect is vital to life on Earth, but relies ~ above a well balanced carbon budget.
The carbon in fossil fuels has actually 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 budget is the end of balance. This contributes to temperatures rising faster than organisms can adapt.
Coal is a black color or brownish rock. We burn charcoal to create energy. Coal is ranked depending on how lot “carbonization” it has actually gone through. Carbonization is the procedure that old organisms experience to end up being coal. Around 3 meter (10 feet) of solid vegetation crushed together right into .3 meter (1 foot) that coal!
Peat is the shortest rank that coal. It has gone through the least amount that carbonization. The is vital fuel in areas of the human being including Scotland, Ireland, and Finland.
Anthracite is the highest possible rank of coal. Anthracite develops in regions of the world where there have been gigantic movements the the earth, such together the development of hill ranges. The Appalachian Mountains, in the eastern part of the joined States, are rich in anthracite.
We mine coal out of the ground for this reason we deserve to burn it because that energy. There space two ways that we deserve to mine coal: underground mining and also surface mining.
Underground mining is provided when the coal is located below the surface of the Earth, occasionally 300 meters (1,000 feet) deep—that’s depths than most of the great Lakes! Miners take an elevator down a mineshaft. Lock operate hefty machinery that cut the coal out of the Earth and brings it over ground. This deserve to be attention work due to the fact that cutting coal have the right to release dangerous gases. The gases can reason explosions or do it tough for miners come breathe.
Surface mining is used when the coal is located an extremely near the surface ar of the earth. To obtain to the coal, service providers must very first clear the area. Lock take far the trees and soil. The coal have the right to then be reduced out that the ground more easily. Entire habitats are destroyed during this process.
About half the electrical energy in the joined States comes from coal. It provides power to our lights, refrigerators, dishwashers, and also most other things us plug in. As soon as coal is burned, it leaves “byproducts” that are also valuable. We usage the byproducts to do cement, plastics, roads, and many various other things.
Coal is a reliable source of energy. We have the right to rely on it day and also night, summer and winter, sunshine or rain, to provide fuel and electricity.
Using charcoal is likewise harmful. Mining is one of the many dangerous work in the world. Charcoal miners room exposed to toxicity dust and also face the risks of cave-ins and also explosions at work.
When charcoal is burned, that releases countless toxic gases and pollutants into the atmosphere. Mining because that coal can likewise cause the floor to cavern in and also create secret fires the burn for decades at a time.
Petroleum is trapped by underground absent formations. In part places, oil bubbles ideal out of the ground. In ~ the LaBrea Tar Pits, in Los Angeles, California, large pools of thick oil bubble up with the ground. Stays of animals that gained trapped there countless years earlier are still maintained in the tar!
Most that the world’s oil is quiet deep under the ground. Us drill v the planet to accessibility the oil. Part deposits space on land, and others room under the s floor.
Once oil companies start drilling through a “drill rig,” they have the right to extract petroleum 24 hrs a day, seven days a week, 365 work a year. Numerous successful oil sites develop oil for around 30 years. Occasionally they can develop oil for much longer.
When oil is under the ocean floor, carriers drill offshore. Lock must develop an oil platform. Oil platforms are few of the biggest manmade structures in the world!
Once the oil has been drilled, it must be refined. Oil contains many chemicals as well as carbon, and also refining the oil takes several of these chemicals out.
We usage oil for plenty of things. About fifty percent of the world’s petroleum is converted into gasoline. The rest deserve to be processed and also used in liquid commodities such as pond polish and also rubbing alcohol, or solid products such as water pipes, shoes, crayons, roofing, vitamin capsules, and also thousands of other items.
There are benefits to drilling for oil. That is relatively inexpensive to extract. The is likewise a reliable and dependable source of energy and money for the regional community.
Oil offers us with countless conveniences. In the type of gasoline, the is a portable resource of power that provides us the power to drive places. Petroleum is additionally an ingredient in many items the we count on.
However, burning petrol is harmful come the environment. It releases hazardous gases and also fumes right into the air that we breathe. Over there is additionally 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 right into the s or surrounding land. Oil pour out are ecological disasters, specifically offshore spills. Oil floats ~ above water, so it can look favor food to fish and ruin birds’ feathers.
Natural gas is one more fossil fuel the is trapped secret in reservoirs. It is mostly consisted of of methane. Friend may have smelled methane before. The decomposing material in landfills also release methane, i beg your pardon smells like rotten eggs.
There is so much herbal gas underground that it is measure in million, billion, or trillion cubic meters.
Natural gas is uncovered in deposits a couple of hundred meter underground. In stimulate to get natural gas out of the ground, providers drill directly down. However, organic gas does not type in large open pockets. Natural gas is trapped in absent formations that deserve to stretch for kilometers.
To reach organic gas, some companies use a process called “hydraulic fracturing,” or fracking. Hydraulic way they use water, and fracturing way to “split apart.” The process uses high-pressure water to separation apart the rocks underground. This releases the natural gas that is trapped in absent formations. If the absent is also hard, they have the right to send acid down the fine to dissolve the rock. Lock can also use tiny grains of glass or sand come prop open the rock and also let the gas escape.
We use organic gas because that heating and cooking. Natural gas can also be burned to generate electricity. We depend on herbal gas to give power to lights, televisions, air conditioners, and kitchen appliances in our homes.
Natural gas can likewise be turned right into a liquid form, dubbed liquid natural gas (LNG). LNG is lot cleaner than any kind of other fossil fuels.
Liquid natural gas bring away up lot less space than the gaseous form. The lot of organic gas that would certainly fit into a big beach round would fit right into a ping-pong round as a liquid! LNG deserve to be easily stored and also used for various purposes. LNG can also be a replacement because that gasoline.
Natural gas is reasonably inexpensive to extract, and is a “cleaner” fossil fuel 보다 oil or coal. When organic gas is burned, it only releases carbon dioxide and also water vapor (which room the exact same gases that we breathe out as soon as we exhale!) This is healthier 보다 burning coal.
However, extracting organic gas can cause environmental problems. Fracturing rocks can cause mini-earthquakes. The high-pressure water and chemicals that are compelled underground can also leak to other sources of water. The water sources, used for drink or bathing, can end up being contaminated and unsafe.
Fossil fuels space the top non-renewable power sources around the world. There are others, however.
Nuclear energy is generally considered one more non-renewable power source. Although nuclear power itself is a renewable power source, the material used in nuclear strength plants is not.
Nuclear energy harvests the an effective energy in the nucleus, or core, of an atom. Nuclear energy is released v nuclear fission, the process where the nucleus of an atom splits. Nuclear power plants are complicated machines the can regulate nuclear fission to produce electricity.
The material most frequently used in nuclear power plants is the element uranium. Although uranium is uncovered in rocks anywhere the world, nuclear power plants typically use a an extremely rare type of uranium, U-235. Uranium is a non-renewable resource.
Nuclear power is a popular means of generating electricity roughly the world. Nuclear power plants carry out not pollute the waiting or emit greenhouse gases. They have the right to be built in landscape or city areas, and also do not damage the environment about them.
However, nuclear power is an overwhelming to harvest. Nuclear power plants are very complicated to build and run. Many neighborhoods do not have actually the scientists and also engineers to construct a safe and reliable nuclear energy program.
Nuclear energy also produces radiation material. Radioactive waste deserve to be exceptionally toxic, causing burns and also increasing the hazard for cancers, blood diseases, and bone decay among people who are exposed to it.
Biomass energy, a renewable power source, can likewise be a non-renewable power source. Biomass energy uses the energy discovered in plants.
Biomass power relies ~ above biomass feedstocks—plants that are processed and burned to create electricity. Biomass feedstocks can include crops such together corn or soy, as well as wood. If world do no replant biomass feedstocks as fast as they use them, biomass energy becomes a non-renewable power source.
Fossilized EnergyAccording come the central Intelligence Agency, the human being generates an ext than 66% of its electrical power from fossil fuels, and also another 8% from nuclear energy.
most valuable kind of coal, include high carbon content. Additionally called tough coal, black color coal, and stone coal.
crop, residue, and other organic product that deserve to be provided to develop energy top top an industrial scale.
greenhouse gas developed by pets during respiration and used by plants throughout photosynthesis. Carbon dioxide is likewise the byproduct of burn fossil fuels.
process usually used to extract oil and natural gas in i m sorry fractures in the Earth"s surface space opened and widened through injecting water, chemicals, and also sand in ~ high pressure. Additionally called hydraulic fracturing.
phenomenon where gases enable sunlight to enter Earth"s atmosphere however make it challenging for warmth to escape.
gas in the atmosphere, such as carbon dioxide, methane, water vapor, and ozone, that absorbs solar warm reflected by the surface of the Earth, warming the atmosphere.
(liquified natural gas) organic gas that has been cooled and liquified because that ease in storage and also transportation.
energy resources that space exhaustible relative to the person life span, such as gas, coal, or petroleum.
large, elevated structure with framework to extract and process oil and natural gas from undersea locations.
layers of partially decayed organic material uncovered in part wetlands. Peat can be dried and burned together fuel.
process whereby plants rotate water, sunlight, and carbon dioxide into water, oxygen, and basic sugars.
byproduct of atom fission that emits a kind of heat, or radiation, that can damage the organization of life organisms.
