- 1Natural ResourceMaterials or substances such as minerals, forests, water, and fertile land that occur in nature and can be used for economic gain.
- 2Renewable ResourceA renewable resource is a resource which can be used repeatedly and replaced naturally. Renewable energy almost never runs out, for example: solar energy is powered by heat from the sun and never runs out.
- 3Non-renewable ResourcesA natural resource such as coal, gas, or oil that, once consumed, cannot be replaced. Most energy resources currently in use are non-renewable while the renewable ones (such as wind and solar power) are not well developed.
- 4Fossil FuelA fuel (such as coal, oil, or natural gas) formed in the earth from plant or animal remains.
- 5Material ResourceMaterial resources are materials found in the natural world that have practical use and value for humans. Material resources include wood, glass (which comes from sand), metals, edible plants, and plastics (which are made from natural chemicals).
- 6Energy ResourceAn energy resource is something that can produce heat, power life, move objects, or produce electricity. Matter that stores energy is called a fuel. Human energy consumption has grown steadily throughout human history.
- 7Nuclear EnergyNuclear energy uses uranium as a fuel. Uranium is a non-renewable environmental resource, so nuclear energy is a non-renewable resource, as well.
- 8FissionNuclear fission is the process in which a large nucleus splits into two smaller nuclei with the release of energy. In other words, fission the process in which a nucleus is divided into two or more fragments, and neutrons and energy are released.
- 9BiomassBiomass is a renewable energy source from living or recently living plant and animal materials which can be used as fuel. An example of biomass is plant material that produces electricity with steam.
- 10Geothermal EnergyGeothermal energy (from the Greek roots geo, meaning earth, and from thermos, meaning heat) is energy made by heat inside the Earth's crust. Although the Sun does heat the surface of the Earth, the heat from inside the Earth is not caused by the Sun.
- 11Wind EnergyWind energy is a form of solar energy. Wind energy (or wind power) describes the process by which wind is used to generate electricity. Wind turbines convert the kinetic energy in the wind into mechanical power.
- 12Hydroelectric EnergyHydroelectric energy is energy derived from the movement of water. Water has mass. It falls and flows downward due to gravity. When it moves, it has kinetic energy which can be harnessed.
- 13Solar Energy1. The energy produced or radiated by the sun. 2. ... Solar energy is used on Earth in various ways. It is used as a passive source of energy, for example, in the form of sunlight that comes through a window and heats up a room.
