100
The definition of a nonrenewable energy resource
energy source with a finite supply
100
A common source of Nuclear power
Uranium
100
The two types of solar energy
passive and active
100
Name ONE drawback of Geothermal energy
Not everywhere on earth has access to geothermal energy reaching close enough to surface to access it
- Cost of drilling that deep in the earth can be very high initially
- Hydrogen sulfide can be released, which is toxic and can be lethal to humans & animals
100
Wind turbines are most effective in this general location
out at sea and high in the air
200
Three fossil fuels
coal, oil, and natural gas
200
What is the process called where atoms of Uranium-235 (the most common type of uranium) are split after being struck by a neutron?
fission
200
This form of solar energy stores light from the sun as electrons in semiconductors
photovoltaic solar cells
200
geothermal energy power plant is similar to a coal power plant
water is heated to turn a turbine and spin a generator
200
disadvantage of wind energy
harming birds bats, noise, ruining aesthetics
300
SNOW STORM TRIPLE
Biomass fuel sources that are easily accessible (can be found and gathered by hand); often used in developing countries as a home heating or cooking fuel
Subsistence Fuels
300
What are is the benefit of Nuclear Energy
No air pollutants (PM, SOx/NOx) or CO2/CH4 released when electricity is generated
300
Two examples of biofuel
ethanol and biodiesel
300
waste product when using a hydrogen fuel cell
water
300
This form of energy is why wind power works
kinetic energy
400
The type of extraction used for natural gas
fracking
400
Besides the possibility of a meltdown & radioactive contamination, what are 2 major drawbacks of nuclear energy?
spent fuel rods, mine tailings, water use, thermal pollution
400
What are THREE ecological drawbacks of dams?
Reservoir floods habitats behind dam
Prevents upstream migration of fish like salmon, that need to swim up to spawning grounds to reproduce
Sedimentation changes upstream & downstream conditions
400
Sources of hydrogen for hydrogen fuel cell
methane, natural gas, water
400
Utility companies use this method to promote energy conservation
price structure based on peak demand
500
What are the main steps of electricity generation?
Heat →Water into Steam → Steam turns a turbine → Turbine powers generator → Generator produces electricity
500
Name the THREE nuclear disasters
Three-Mile-Island
Chernobyl
Fukushima
500
What is the difference between Modern Carbon and Fossil Carbon?
burning biomass: modern carbon (CO2 that was recently sequestered, or taken out of the atmosphere)
buring FF: fossil carbon that had been stored for millions of years
500
What is a ground source heat pump and geothermal heating?
Heat absorbing fluid is pumped through a pipe into the ground where it either takes on heat from the ground, or gives off heat to the ground
- Geothermal heating involves piping water deep into ground to be heated by magma & then transfering heat from water to the building
500
Name 3 SMALL Scale and 3 LARGE Scale Energy conservations
Small:Lowering thermostat to use less heat or use AC less often, Conserving water with native plants instead of grass, low flow shower heads, efficient toilets, dishwashers, dryers, Energy efficient appliances, better insulation to keep more heat in home
Large: Improving fuel efficiency (fuel economy) standards, tax credis, public transporation, sustainable building design, managing peak demand, smart grid
