Energy And Its Types Flashcards
What is the basic need of living things?
Energy
Life cannot exist without…
Energy
It is produced by nature and inexhaustible (abundant)
Renewable energy
It moves highspeed, energies used are depleting. Example of this are wind mills.
Wind energy
The ability to work a technology, the movement of an object powered by energy resources.
Energy
An energy resource produced by the sun.
Solar energy
Low solar energy includes…
heating water, air for cooking, drying
High solar energy includes…
electricity used in communities
Solar panels are made of what?
Solar cells
A type of renewable energy resource that saves the fuel reserves and power generated from moving water like river. Usually restored in dams and water reservoir.
Hydro energy
A renewable energy resource produced beneath Earth’s surface.
Geothermal energy
High temperature underground heats water and creates steam, which run the turbines in converting electrical energy.
Geothermal energy process
Refers to the rise and fall of the water level of the ocean which is influenced by gravitational force of the moon.
Tidal energy
Produced when burning radioactive elements undergo nuclear fission.
Nuclear energy
Examples of nuclear energy includes…
fossil fuels, coal, natural gas, petroleum
Energy resources that can run out in the future and takes a long time to replace/can’t be replaced.
Non-renewable energy
Formed a long time ago due to degradation of animals and plants on the ground under high pressure and temperature, referred to as main source of fossil fuels.
Coal
Thick, black liquid that formed upon decomposition of liquid organic matter when organisms die and sink at the bottom of the ocean, decomposition of natural gas.
Petroleum/Crude
Came from fossils and often colorless. Main component is methane, used for cooking (LPG) and fuels automobiles.
Natural gas
Wind energy resources located on land, on top of hills and open fields, driven by the natural movement of the air.
Onshore wind energy
Wind energy resources located in shallow water and generates electricity from wind blowing across the sea
Offshore wind energy
