Renewable Energy Vocab Flashcards
Ore
A mineral or aggregate of minerals from which a valuable constituent,especially a metal, can be profitably mined or extracted
Mineral resource
Natural resources in the form of minerals
Surface mining
Method of mining used to extract minerals and metals which are near the surface of the earth
Spoils
To damage severely or harm (something) especially with reference to its excellence,value,usefulness,etc
Overburden
To load with too great a burden,overload
Open pit mining
A kind of surface mining. Mining companies choose this way to get rocks and minerals out of the ground because it is the easiest ad cheapest way to do it only if rocks and minerals we close to the surface of the land
Strip mining
A type of surface mining that involves excavating earth,rock,and other material to uncover a tabula,lens shaped,or layered mineral reserve.Mineral extracted usually coal or other rocks of sedimentary origin
Contour
An outline especially of a curving or irregular figure
Smelting
Process by which a metal is obtained,either as the element or as a simple compound from its ore by heating beyond the melting point,ordinarily in the presence of oxidizing agents, such as air,reducing agents such as coke
Depletion time
Similar to depreciation in that it is cost recovery system for accounting and tax reporting
Net energy
A concept used in energy economies that refers tothe difference between te energy expended to harvest an energy source and the amount of energy gained from the havest
Petroleum
Oil that is found underground,oil can be thick and black as far or thin as water.It has a lot of energy.We can turn it into different fuels like gasoline,kerosene, and heating oil
Crude oil
Fossil fuel that was naturally from decaying plants and animals living in ancient seas.Vary in color and in viscosity contain hydrocarbons
Peak production
A hypothetical date referring to the worlds peak crude oil production where by following this day production rates will begin to diminish
Petrochemicals
Are chemical products derived from petroleum
Oil reserves proven vs unproven
Answer
Tar sand
Loose sand or partially consolidated sandstone containing naturally occurring mixtures of sand,clay,and water saturated with viscous from of petroleum. (Bitumen)
Shale oil
Unconventional oil produced from oil shale by pyrolysis,hydro generation,or thermal dissolution
Natural gas
A fossil fuel formed when plants and animals are exposed to intense heat and pressure over thousands of years
Coal
A black or dark brown combustible mineral substance consisting of carbonized vegetable matter used as a fuel
Synthetic natural gas
Fuel gas that can be produced from fossil fuels such as Iignite coal or from biofuels when it is named BIO SNG or from renewable electrical energy
Nuclear fusion
Nuclear reaction in which two or more atomic nuclei collide at a very high speed and join to form a new type of atomic nucleus
Energy efficiency
Using less energy to provide the same service there are definitions,but this is a good operational one.
Cogeneration
A single fuel source,such as natural gas,is used to produce both electrical and thermal energy
