Unit 6

A use of technology that captures and stores the energy of sunlight with electrical equipment and devices.

A diesel substitute produced by extracting and chemically altering oil from plants.

Old carbon contained in fossil fuels.

An energy source that cannot be used up.

A brown coal that is a soft sedimentary rock that sometimes shows traces of plant structure; it typically contains 60 to 70 percent carbon.

The chemical reaction between any fossil fuel and oxygen resulting in the production of carbon dioxide, water, and the release of energy.

The emission of ionizing radiation or particles caused by the spontaneous disintegration of atomic nuclei.

A colorless, odorless gas that is formed during incomplete combustion of most materials.

Short for hydraulic fracturing, a method of oil and gas extraction that uses high-pressure fluids to force open existing cracks in rocks deep underground.

Liquid fuel created from processed or refined biomass.

The maximum electrical output of something such as a power plant.

Electricity generated from the nuclear energy contained in nuclear fuel.

A measurement of the rate at which a sample of radioactive material decays; 1 Bq is equal to the decay of one atom per second.

The ease with which an energy source can be used to do work.

An ethanol derived from cellulose, the cell wall material in plants.

A by-product of all combustion, carbon dioxide from biofuels contains modern carbon from woody material, rather than fossil carbon from fossil fuels.

Contains greater than 90 percent carbon. It has the highest quantity of energy per volume of coal and the fewest impurities.

An energy source such as electricity that can move and deliver energy in a convenient, usable form to end users.

A use of energy from the sun that takes advantage of solar radiation without active technology.

A turbine that converts the kinetic energy of moving air into electricity.

A device that can be turned by water, steam, or wind to produce power such as electricity.

Nuclear fuel that can no longer produce enough heat to be useful in a power plant but continues to emit radioactivity.

A black or dark brown coal that contains bitumen. It typically contains up to 80 percent carbon.

Carbon in biomass that was recently in the atmosphere.
