| main component of coal | carbon |
| How was coal formed | sedimentary rock so formed by dead pressurized organic matter |
| What are the three main types of coal | bituminous, lignite, anthracite |
| Strip mining | Surface mining:soil & rock stripped off to reach coal Most common method of extraction |
| Subsurface mining | 40% of U.S. mining Dangerous🡪accidents, black lung Labor intensive |
| coal mining environmental impact | Environmentally destructive, rain & spoil produces sulfuric acid🡪water pollution Acid drainage, land subsidence |
| health problems associated with coal mining | coal mine dust can also cause many illnesses such as pulmonary diseases and black lung |
| US Mining Law of 1872 | opening mining and purchasing on united states public federal land |
| What country has the largest coal reserves | united states |
| what country is the has the largest coal reserves and is largest importer/ exporter of coal | china |
| What is the main component of oil | hydrocarbons such as hydrogen, carbon ,sulfur ,nitrogen and oxygen |
| How is oil separated into its different products | fractional distillation which is when crude oil is heated to vapor then vapor is cooled to separate different components by their boiling points |
| members of OPEC | middle eastern countries such as venezuela, qatar, alegria, equatorial guinea, ecuador |
| main component of shale oil | kerogen |
| main component of tar sand | bitumen is the main component of tar sand. Tar sand is a mixture of sand,clay,water and bitumen |
| main component of natural gas | methane |
| Where is conventional natural gas found | conventional lies ontop of crude oil and unconventional found in rocks |
| process called when natural gas is removed from shale rock | hydraulic fracturing. which is when pressurized fluid is injected into rock formations to break them up and release natural gas |
| what is the cleanist nonrenewable energy | natural gas |
| What is used as the fuel source for nuclear power | uranium |
| Where have nuclear accidents occurred | nuclear accidents have occurred in chernobyl ukraine and fukushima japan |
| passive energy | passive energy works through structural designs that optimize the use of light and heat form direct sunlight. |
| active solar energy | active solar energy works with objects or devices that converts sunlight into electricity or heat using photovoltaic cells |
| main ingredient found in photovoltaic cells | silicon |
| first country to harness wind energy | denmark |
| fastest growing renewable energy | wind |
| u.s oil reserves will be depleted in how many years | 50 |
| what is the least energy efficient device | incandescent light |
| why is incandescent light the least energy efficient | produced more wasteful heat than light |
| when energy is transferred much is loss to lower quality energy usually heat | second law of thermodynamics |
| is florescent lights energy efficient | yes |
| advantages of hydro electrical power | control flooding, low operating cost, lower pollution |
| country that has made the largest commitment to renewable energy share | china |
| what parts slows down neutron to create fission | control rod |
| most times _________________ resources are known for using steam | nonrenewable |
| what is the most expensive method for generating electricity | photovoltaic cells |
| the greatest use of electrical power is during | the summer |
| when was chernobyl | 1986 |
