List the four nonrenewable sources of energy.
Nuclear, oil, coal, natural gas
What is the cheapest renewable energy source? (hint: popular in developing nations)
Biomass or passive solar
Double Points
How have subsides impacted renewable energy usage in recent years?
Increased it
Imagine a country uses 182,320 pounds of coal. In the past they used 235,678 pounds. What is the percent change?
-23%
Which fossil fuel is most commonly used for electricity generation (not transportation)?
Coal
Which renewable energy source uses technology with toxic metals which need to be mined?
Solar (PV cells)
steal 200 from one team
Which renewable energy source can increase erosion?
Hydroelectric
Explain the basics of how a coal powerplant works.
Burn coal, boil water, creates steam, turns turbine, goes to generator, creates electricity
Define cogeneration
One fuel source produces waste heat and electricity
Propose a solution for wind energy’s impact on birds and bats.
TURN OFF TURBINES/ MOVE THEM FROM MIGRATORY PATHS, EMIT HIGH FREQUENCY SOUNDS
How do offshore wind farms compare to those on land?
More energy production
steal 300 from one team
What type of environments produce coal? How about oil/ natural gas? (over millions of years)
Coal- swampy
Oil/ Natural Gas- marine
Double points
Which nonrenewable energy resource is associated with thermal pollution?
Nuclear
Double points
Which renewable energy source is associated most closely with deforestation?
Biomass
Generating hydroelectric power in the ocean is called...
tidal power
Each gallon of fuel releases approximately 20 pounds of CO2. One person drives 30,000 miles in a car that averages 32 mpg, and another drives 30,000 miles in a car that averages 24 mpg. How many more pounds of co2 are emitted by the car with 24 mpg?
6,250 pounds
List the conditions necessary for coal formation (at least 3; not location).
Anerobic, acidic, high pressure, time, etc.
Which energy source originates from Earth’s interior and not the sun?
Geothermal
No one else collects
Give an example of passive and an example of active solar energy.
Passive- windows, greenhouses
Active- PV cells (anything with technology)
There are 5 stages to coal production as time and pressure increase. List them in order
PEAT, LIGNITE, SUB-BITIMOUS, BITIMOUS, ANTHRACITE
