Wind energy (or wind power) refers to the process of creating electricity using the wind, or air flows that occur naturally in the earth's atmosphere. Modern wind turbines are used to capture kinetic energy from the wind and generate electricity.
-
Marine energy refers to seawater-based renewable energy, including tidal energy, wave energy, ocean current energy, and energy created from temperature and salinity differences. The energy density of various ocean energies is relatively low in general.
-
Biomass energy is energy generated or produced by living or once-living organisms. The most common biomass materials used for energy are plants, such as corn and soy, above. The energy from these organisms can be burned to create heat or converted into electricity.
-
