What percentage of the world’s commercial energy is furnished by fossil fuel?
90% The Middle East has about 62 percent of the world's oil reserves. 90% of the world's commercial energy is furnished by fossil fuels.
Which of the following processes involves removing materials from the top of a vein of coal to get to the coal beneath?
Mountaintop removal mining (MTR) is a form of coal mining that mines coal seams beneath mountaintops by first removing the mountaintop overlying the coal seam.
Which one of the following is the most efficient method of using solar energy to produce electricity?
Currently, the most successful method of harnessing and using solar energy to produce electricity is the photovoltaic devices.
Is hydraulic fracturing and fracking the same thing?
Hydraulic fracturing, or fracking, is a drilling method used to extract petroleum (oil) or natural gas from deep in the Earth. In the fracking process, cracks in and below the Earth's surface are opened and widened by injecting water, chemicals, and sand at high pressure.
Which of the following is an environmental problem associated with hydroelectric power quizlet?
Environmental problems associated with large hydroelectric dams include? Loss of fertile farmland, destruction of aquatic communities and relocation of people.
When was fossil fuels first discovered?
Around 4,000 years ago, someone in northern China came across an odd black rock. It was one of many. Then this person discovered something. Somehow this person discovered that the rock could burn.
When was energy invented?
Thomas Young (1773 − 1829) first introduced the word “energy” to the field of physics in 1800, but the word did not gain popularity. Thomas Young later established the wave nature of light through interference experiments.
What is the process of coal mining?
Surface coal mining involves:
- removing parts or all of mountaintops to expose buried seams of coal, and.
- disposing in adjacent valleys the excess: "overburden" (rock above the coal seam), and. "interburden" (rock between coal seams).

What is the process of coal formation called?
The formation of coal occurs over millions of years via a process known as carbonation. In this process, dead vegetation is converted into carbon-rich coal under very high temperature and pressure.
What is the process of converting solar energy into electricity?
Solar technologies convert sunlight into electrical energy either through photovoltaic (PV) panels or through mirrors that concentrate solar radiation. This energy can be used to generate electricity or be stored in batteries or thermal storage.
What is the most efficient solar energy system?
Monocrystalline solar panels are often touted as the most efficient option and are therefore best when installed for larger energy systems in commercial and residential properties. However, panel sizes do vary; therefore, monocrystalline can be used in smaller installations as well.
What is the fracking process?
Hydraulic fracturing, or fracking, is a drilling method used to extract petroleum (oil) or natural gas from deep in the Earth. In the fracking process, cracks in and below the Earth's surface are opened and widened by injecting water, chemicals, and sand at high pressure.
What is hydrofracking a well?
Hydro-fracturing, commonly referred to as hydro-fracking, is a well development process that has been used commonly in the water well industry since the 1990s. Hydro-fracturing involves using direct displacement specialized high pressure pumps to inject water under high pressure into a bedrock formation via the well.
Which of the following is a major environmental problem with building hydroelectric dams?
Flooding land for a hydroelectric reservoir has an extreme environmental impact: it destroys forest, wildlife habitat, agricultural land, and scenic lands. In many instances, such as the Three Gorges Dam in China, entire communities have also had to be relocated to make way for reservoirs (3).
Which of the following environmental problems is most often linked with the combustion of fossil fuels?
Water pollution: From oil spills to fracking fluids, fossil fuels cause water pollution.
What is coal fossil fuel?
Coal is called a fossil fuel because it was made from plants that were once alive! Since coal comes from plants, and plants get their energy from the sun, the energy in coal also came from the sun. The coal we use today took millions of years to form.
Where does gas come from for cars?
U.S. petroleum refineries make gasoline and other petroleum products from crude oil and other liquids that are produced in the United States or imported from other countries. Nearly all of the gasoline sold in the United States is produced in the United States.
Who invented current?
Benjamin Franklin is given the credit for discovering electricity. In the year 1752, Benjamin Franklin conducted an experiment using a kite and key on a rainy day. He wanted to demonstrate the relationship between lightning and electricity. He flew the kite tied with a key during the thunderstorm.
Who created electric?

What are the steps of the mining process?
The mining industry operates through a sequence of stages: exploration, discovery, development, production and reclamation. All stages of this Mining Cycle provide direct economic stimulus.
What are the methods used in surface mining?
There are five recognized types of surface mining, each with specific variations depending on the minerals being extracted. These include strip mining, open-pit mining, mountaintop removal, dredging and highwall mining.
What is called carbonisation?
Carbonisation is the term used when complex carbonaceous substances such as wood or agricultural residues are broken down by heating into elemental carbon and chemical compounds which may also contain some carbon in their chemical structure.
What is coalification process?
Coalification is defined as the process of gradual change in the physical and chemical properties of coal as pressure and temperature increase during geological time.
What is a hydroelectric system?
Hydroelectric energy, also called hydroelectric power or hydroelectricity, is a form of energy that harnesses the power of water in motion—such as water flowing over a waterfall—to generate electricity. People have used this force for millennia.
What is photovoltaic technology?
