Energy Sources
This energy source requires damming which can change the wildlife habitats around it
What is hydroelectric power?
In the water analogy, the people walking in the circuit represented what?
What are electrons?
What are the 2 main parts of a speaker that are necessary to create sound?
What are a copper wire and magnet?
In terms of consumption, Oregon uses most of it's energy to provide what? (transportation fuel, direct use fuel, or electricity)
What is the energy source for solar power?
What is the sun (or photons from the sun)?
These photons hit solar panels (usually made from silicon) which releases electrons and produces an electric charge
This energy source is the most CO2 intensive fuel
What is coal?
Electrical energy
How is an electromagnet created?
What is when a current goes through the copper wire?
What year did the last coal plant shut down in Oregon?
What is the year 2020?
What is the energy source for hydropower?
What is flowing water? (or water that is channeled through a pipe that then pushes a turbine to power a generator)
This energy source requires a lot of land and is best in sunny areas
What is solar power?
In the water analogy, the yellow water in the volumetric flask represented what?
Why is there a net force to push the speaker coil away from the permanent magnet when an initial electromagnet is created?
What is because the same pole (north) of the electromagnet is facing the same pole (north) of the permanent magnet?
Name 1 energy source that Oregon imports.
What is natural gas, coal, or petroleum?
What is the energy source for nuclear power?
What is the splitting of uranium atoms via fission?
This energy source takes energy from the earth and turns it into mechanical energy
What is geothermal power?
In the water analogy, we did an exercise where electrons (people) moved quickly to dispense their electrical energy to the light bulb. This rate of electrons per second represents what about a circuit?
What is the current?
What does a motor do?
Name 1 energy source that Oregon produces.
What is hydro, wind, solar, geothermal, or nuclear?
What is the energy source for wind power?
What is the mechanical energy of wind? (which then pushes the wind turbine blades around a rotor that spins a generator to make electricity)
This energy source is cheap, but has high land use impact and still creates some greenhouse gasses
What is natural gas?
What is Power?
Why is it necessary for the speaker coil/speaker cone to move to create sound waves?
What is the push and pull of the speaker is what creates the high and low pressure of air particles that move as sound waves (to then push against your ear drum and have your brain perceive that motion as sound)?
Most of Oregon's electricity comes from what energy source?
What is hydro(electric) power?
What is the energy source for biomass?
What is the chemical energy stored in organic matter? (which was created from sun energy originally and then is often burned and used to heat up water which creates steam and that spins a turbine that powers a generator to create electricity)
