Vocabulary: Energy Resources

Front

Thermal energy from earth's interior

Back

Geothermal energy is the heat that comes from the sub-surface of the earth. It is contained in the rocks and fluids beneath the earth's crust and can be found as far down to the hot molten rock, magma.

Front

A process in which mined land must be recovered with soil and re-planted with vegetation

Back

Reclamation is the process of restoring land that has been disturbed by mining or other activities to a natural or economically usable state.

Front

A natural resource that can be replenished by natural processes, at least as quickly as it is being used

Back

Renewable energy resources are sources of energy that can be replenished naturally, such as solar, wind, and hydro energy.

Front

Energy from the sun

Back

Solar energy is the energy that comes from the sun's radiation. It can be converted into thermal or electrical energy.

Front

A natural resource that is being used up faster than it can be replaced by natural processes

Back

Non-renewable energy refers to resources like fossil fuels (coal, oil, natural gas) that cannot be replenished in a short time frame.

Front

Energy derived from organic materials

Back

Biomass energy is produced from organic materials, such as plants and animal waste, and can be used for heating, electricity, and transportation.

Front

Energy produced by the movement of air

Back

Wind energy is generated by converting the kinetic energy from wind into mechanical power or electricity using wind turbines.

Front

Energy produced from the heat generated by nuclear reactions

Back

Nuclear energy is the energy released during nuclear fission or fusion, especially when used to generate electricity.

Front

The process of converting sunlight into electricity

Back

Photovoltaics is the technology that converts solar energy directly into electricity using solar panels.

Front

A type of energy that is not renewable and can deplete over time

Back

Fossil fuels are non-renewable energy sources formed from the remains of ancient plants and animals, including coal, oil, and natural gas.
