Renewable energy source derived from living or recently living organic materials. Examples: Wood, agricultural residues, and manure.

The variety and variability of life on Earth, considered as a resource for foods, medicines, and ecosystem services. Examples: Genetic diversity, species diversity, and ecosystem diversity.

Renewable energy from the sun, captured and converted into electricity or heat. Examples: Photovoltaic solar panels and solar thermal systems.

The layers of gases surrounding Earth, which can be considered a resource for activities like wind generation and aviation. Examples: Oxygen for breathing, wind for energy, and carbon dioxide for plant growth.

Extraterrestrial materials found on other planets, moons, and asteroids. Examples: Lunar regolith, helium-3, and water ice from Mars or the Moon.

A type of non-renewable resource formed from the remains of dead plants and animals over millions of years. Examples: Oil, coal, and natural gas.

Resources obtained from the sea and ocean ecosystems. Examples: Fish, crustaceans, seaweed, and coral reefs.

Minerals that can be smelted or treated to produce a useful metal. Examples: Iron ore, bauxite (for aluminum), copper, and gold.

A type of non-renewable resource used to produce nuclear energy via fission or fusion reactions. Examples: Uranium and thorium.

Renewable energy derived from the kinetic energy of wind converted into electricity. Examples: Wind turbines on wind farms or individual units.

The non-material benefits people obtain from ecosystems like recreation and aesthetic enjoyment. Examples: National parks, cultural heritage sites, and landscapes.

Benefits provided by ecosystems that contribute to making human life both possible and worth living. Examples: Pollination, water purification, and climate regulation.

Renewable energy generated by the gravitational force of falling or flowing water. Examples: Dams, water turbines, and hydro stations.

Renewable energy harnessed from the movement of ocean tides. Examples: Tidal barrages, tidal fences, and tidal turbines.

Resources that can be replenished naturally at a rate comparable to their rate of consumption. Examples: Solar energy, wind energy, and timber from forests.

An accumulation of partially decayed vegetation or organic matter that is unique to natural areas called peatlands. Examples: Fuel peat and horticultural peat.

Naturally occurring inorganic substances with a definite chemical composition. Examples: Gold, silver, copper, and diamonds.

The supply of water available from surface and underground sources for human use. Examples: Rivers, lakes, groundwater, and glaciers.

Renewable fuels made from living organisms or their byproducts. Examples: Ethanol from corn, biodiesel from vegetable oil, and biogas from animal waste.

A fossil fuel used as a source of energy for heating, cooking, and electricity generation. Examples: Methane and ethane.

The usable portion of the earth's surface for agriculture, urban development, and conservation. Examples: Farmland, urban areas, and natural parks.

Minerals not used for their metal content but for their physical and chemical properties. Examples: Sand, gravel, phosphates, and salts.

A combustible black or brownish-black sedimentary rock used primarily as an energy source. Examples: Anthracite, bituminous, and lignite coal.

Minerals that contain a significant amount of radioactive elements. Examples: Uraninite (uranium ore) and thorite (thorium ore).

Resources that exist in finite quantities and are not replenished on a human timescale. Examples: Fossil fuels (oil, natural gas, coal) and minerals.

The top layer of the earth's crust that supports plant life and various ecosystems. Examples: Topsoil, peat, and loamy soil.

The management, cultivation, and harvesting of trees and other vegetation in forested areas. Examples: Timber for construction, paper products, and natural resins.

A set of 17 chemical elements used in many high-tech devices. Examples: Neodymium (for magnets), lanthanum (in camera lenses), and cerium (in catalysts).

Renewable energy taken from the surface waves of the ocean and converted into electricity. Examples: Wave energy converters, oscillating water columns, and point absorbers.
