Renewable Vs Nonrenewable Sources
This type of energy source has a finite supply and includes fossil fuels.
What is nonrenewable energy?
This is the most abundant and dirtiest fossil fuel.
What is Coal?
This is the CORRECT way of pronouncing Appalachia.
"Apple-atcha"
Say it wrong and I'll throw an "apple-atcha"
This process splits large atomic nuclei to release energy in nuclear reactors.
What is fission?
This unit, often seen on electric bills, represents the amount of energy used over a specific period.
What is a kilowatt-hour (kWh)?
This type of energy source can regenerate indefinitely if not overharvested.
What is potentially renewable energy?
This process uses pressure and "mini-earthquakes" to extract oil and gas from small spaces and cracks in bedrock.
What is hydraulic fracturing (fracking)?
This technique of surface mining removes the peaks of landscapes to access underlying coal deposits, and has been a source of controversy in West Virginia for decades.
What is mountaintop removal?
This theoretical power source involves forcing lighter nuclei together to produce heavier nuclei.
What is fusion?
A small fan draws 3.5 watts of power to operate and runs for 7,300 hours in a year. What is the energy usage of the fan, in kilowatt-hours (kWh) per year
25.6 kWh per year
3.5W × 7,300hours = 25,550Wh
25,550Wh = 25.55kWh
solar, wind, biomass, and geothermal.
All of these are considered nondepletable except for THIS fuel.
What is biomass?
This is known as the highest quality version of Coal.
What is Anthracite?
This mining method involves searching for precious metals or stones in river sediments.
What is placer mining?
This is nuclear fuel, commonly used in reactors.
(GIVE ITS COMPLETE NAME)
What is Uranium-235?
Baltimore has started using more renewable energy so the CO₂ emissions dropped from 2.5 million metric tons in 2014 to 1.8 million metric tons in 2024. What is the percent change in emissions?
The percent decrease in emissions is 28%.
Old Value - New Value / Old Value × 100
1.8 − 2.5 / 2.5 × 100 = -28%
This is a ratio that measures how much usable energy is produced by a system relative to the amount of energy used to create it.
What is EROEI or EROI?
Energy Return on Energy Invested
This process converts coal into synthetic oil.
What is CTL (Coal-to-Liquid)?
This term refers to the process of restoring disturbed land to a state similar to its original natural condition.
What is Reclamation?
The material in control rods, such as boron, absorbs these particles to control nuclear reactions.
What are neutrons?
If a washing machine uses 800 watts of energy per hour and energy costs $0.14 per kWh, how much would it cost to operate the washing machine continuously for 15 days?
$40.32
0.8kW × 24hours= 19.2kWh/day
19.2kWh/day × 15days= 288kWh
288kWh × $0.14/kWh= $40.32
Corn can be turned into THIS a type of Biofuel that can be used to power cars and lessen the U.S.'s dependency on foreign oil.
What is corn ethanol?
THIS is used for predicting the likely production rate of any finite resource over time. When plotted on a chart, the result resembles a symmetrical bell-shaped curve.
What is The Hubbert Curve?
This disease, often caused by prolonged exposure to coal dust in subsurface mining, severely impacts respiratory health.
This is a type of Nuclear Power reactor that generates steam indirectly by transferring heat away from the reactor core and pressurizing it in a separate system.
What is a Pressurized Water Reactor?
A technician is handling 500 grams of a radioactive isotope with a half-life of 200 years. How much of the mass will remain after 1,000 years?
15.625g
Number of half-lives = Total Time / Half-life
1000years / 200years = 5
After 1 half-life: 500 ÷ 2 = 250g
After 2 half-lives: 250 ÷ 2 = 125g
After 3 half-lives: 125 ÷ 2 = 62.5g
After 4 half-lives: 62.5 ÷ 2 = 31.25g
After 5 half-lives: 31.25 ÷ 2 = 15.625g
