Energy and Environmental Concepts

Front

Biofuel

Back

Fuel derived from organic matter (plants or animal waste) that can be replenished over time.

Front

Conservation

Back

The careful use of natural resources to prevent depletion and ensure sustainability.

Front

Emissions

Back

The release of gases, particularly greenhouse gases like carbon dioxide and methane, into the atmosphere from sources like vehicles, factories, and power plants.

Front

Fossil Fuel

Back

Natural fuels such as coal, oil, and natural gas formed from the remains of ancient plants and animals over millions of years.

Front

Geothermal

Back

Energy derived from the heat stored beneath the Earth's surface.

Front

Hydropower

Back

Energy generated by the movement of water, typically using dams to harness the flow of rivers.

Front

Microbe

Back

A microscopic organism; in energy contexts, microbes can be used to break down waste or create biofuels.

Front

(Non) Renewable Energy

Back

Renewable energy: Comes from sources that are naturally replenished (e.g., solar, wind, hydro). Non-renewable energy: Comes from finite sources that will eventually run out (e.g., coal, oil).

Front

Reserves

Back

Known quantities of natural resources (like oil or coal) that can be extracted for use.

Front

Reservoir

Back

A natural or artificial lake where water is stored for use in hydropower or irrigation.
