100
This is stored in fuel rods and takes thousands of years to become non-reactive
What is U-235?
100
It is a solid fossil fuel that is formed in several stages as the buried remains of land plants that lived 300-400 million years ago were subjected to intense heat and pressure
What is coal?
100
used to seperate hydrogen from water
What is electrolysis?
100
decomposition of dead, decaying, animals
How is oil formed?
100
Sunlight collected and focused on oil filled pipes running through middle of large area of curved solar collectors
What is a solar thermal plant?
200
large fuel supply, low environmental impact (without accidents), emits 1/6 as much carbon dioxide as coal, moderate land disruption and water pollution (without accidents), moderate land use, and low risk of accidents
What are advantages of nuclear power?
200
Soft coal, most often used, high heat content, large supplies, and high sulfur content
What is bituminous coal?
200
has a small traditional gasoline powered motor and an electric motor used to provide the energy needed for acceleration and hill climbing
What is a hybrid car?
200
petrochemicals, paint medicines, plastics, and pesticides
What are oil products?
200
steady winds needed, back up system needed, high land use, visual pollution, noise when located near poplulated area, and may indanger migritory birds
What are the disadvantages of wind power?
300
cancer, miscarriages, and radiation poisoning
What are health effects of nuclear power?
300
Ample supplies, hight net energy yeild, low cost with subsidies, severe land disturbance, air pollution, and water pollution, high land use and severe threat to human health
What are advantages and disadvantages of coal?
300
sugarcane, corn, rice, and switchgrass
What are crops that can be converted to ethonal?
300
amply supply, high net energy yield, easily transported, low land use, efficient distrubution systems
What are the advantages of conventional oil?
300
stone floor and wall for heat storage, super window, windows facing south, heavy insulator, with deciduous trees
What is passive design of a home?
400
low net energy yield, cannot compete economically withou huge government subsidies, high environmental impact, and major acciendents like Chernobyl
What are disadvantages of nuclear power?
400
US, Russia, China
What are the countries with the most coal?
400
Hydrogen, air, biodiesel, solar, hybrid, and ethanol fueled
What are the types of energy efficient cars?
400
this bi-product of oil sand can omit sulfur dioxide causing acid rain
What is bitumen?
400
high efficiency, moderate net energy, low carbon dioxide emissions, low cost, low land use, and low land disturbance
What are the advantages of geothermal energy?
500
1.) Enriched uranium is formed and stored in rods 2.) Rods placed in pressure vessel which allows Uranium to melt 3.) Control rods raised and lowered to control rate of nucear reaction 4.) The bundle of Uranium is heat source which can produce steam to spin turbines and create power
What are steps to how a nuclear reactor works?
500
Generates 62% of worlds elctricity, but 66% of energy released by burning coal is lost
What is a coal burning power plant?
500
not found in nature, energy is needed to produce fuel, negative net energy, carbon dioxide emmisions if produced from carbon containing compounds, high cost, short driving range, and no fuel distrubtion system in place
What are the disadvanatges of hydrogen fuel?
500
based on their boiling points components are removed at various levels and the ones with the lowest boiling points are on top
What is the distillation column?
500
The largest dam that produces as much energy as 18 coal power plants
What is the Three Gorges Dam?
