Match the renewable energy source with its definition.

• Geothermal

• the most abundant of all energy resources and can even be harnessed in cloudy weather.

• Bioenergy

• produced from a variety of organic materials, called biomass, such as wood, charcoal, dung and other manures for heat and power production, and agricultural crops for liquid biofuels

• Wind

• harnesses the energy of water moving from higher to lower elevations.

• Hydropower

• harnesses the kinetic energy of moving air by using large wind turbines located on land (onshore) or in sea- or freshwater (offshore)

• Solar

• utilizes the accessible thermal energy from the Earth’s interior.
