Definitions
The ability of someone or something to do work
What is the definition of energy?
The kind of energy we get from the food we eat
What is chemical energy?
Dead animals, plants, and other organisms that were buried under sediment without oxygen and under high pressure
What are fossil fuels?
Energy that can be used over and over and will not run out and does not cause pollution.
What is renewable energy?
A new method that has made it easier to extract natural gas trapped in rock layers
What is hydraulic fracturing, or fracking?
Making things move
What is the definition of work?
What we call the law that says no more energy can be used than was originally input
What is the law of the conservation of energy?
A non-renewable type of hardened, combustible carbon we burn for fuel
What is coal?
Renewable energy source that utilizes steam from the heat under the earth
What is Geothermal Energy?
This is how we get coal, which is destructive and dangerous for workers, causing coal to be a controversial energy source.
What is mining?
Energy of motion
What is Kinetic Energy?
What we say when one form of energy is turned into another form, like potential into kinetic
What is converted?
A fossil fuel in gas form that is trapped in rocks, usually near oil deposits
What is Natural Gas?
We cannot generate enough energy to fit the market, the availability is not constant and it is very expensive to set up.
What are some disadvantages of renewable energy?
What is drilling?
Energy of position
What is potential energy?
Exactly as much potential energy was stored up
How much kinetic energy can be used?
The use of a nuclear reaction due to fission to produce electricity
What is nuclear energy?
The true hope for energy production in the future
Hydrogen and Fusion
This is a renewable energy source that uses a fuel that burns cleanly
What is biomass or biofuel?
The two main kinds of energy
What are kinetic and potential energy?
Dams and wind turbines harness the motion of water and wind to turn this and create electricity
What is a generator?
Energy sources that, eventually, will run out and it will be impossible to make more
What is non-renewable energy?
This type of solar panel converts sunlight directly into electricity
What are solar cells?
The extraction process is much more regulated and harmful gas has been captured, replaced, or used elsewhere
What improvements have been made to extraction of fuels?
